Abstract
The early stages of transformation of centrally planned economies into market economies are examined. In the transitional phase when an economy is no longer centrally planned, but not yet market based—when it is a “previously centrally planned economy”—expectations play a key role. A model is developed to analyze the consequences of expected price liberalization, and the benefits from early development of financial markets and speedy implementation of price reform are demonstrated. Ways to reduce liquidity overhang are examined, the consequences of privatization are analyzed, and the benefits of an effective tax system are highlighted.
This paper deals with key issues arising during the early stages of transformation of centrally planned economies (CPEs) into functioning market economies (MEs). The analysis is motivated by the recent experience with economic transformation and restructuring in Eastern Europe and the U.S.S.R. The economic system in CPEs launching such a transformation is highly distorted. Prices do not represent real social costs, incentives systems are absent, losses of unprofitable state-owned enterprises are automatically financed, legislation vital for the functioning of markets is not in place, private ownership and property rights are underdeveloped, markets are missing, shortages prevail and, occasionally, inflation is high.
In analyzing this transformation, it is relatively simple to characterize the initial conditions of CPEs, as well as to specify the features of MEs. It is more difficult to provide an analytical framework that highlights the process of transition. During the transition period the old central planning system is dismantled (or is collapsing), while the new market system (and its associated institutions and policies) is still not in place. This transition period, during which the economy is no longer centrally planned, but has not yet achieved the status of a market economy, may be quite long. The economy during that period is referred to as a “previously centrally planned economy” (PCPE). On its way to reform, a centrally planned economy is likely to spend a significant period as a PCPE before becoming an ME.
There are many ways to transform a CPE into an ME. Since neither history nor economic theory provides a clear guide to the optimal pace and sequence of reform measures, it is unlikely that a “master blueprint” for economic transformation could be found. Rather, the solution for the optimal pace and sequence of reform measures is likely to depend on the special circumstances prevailing in each of these economies.1
The process of economic transformation and restructuring is bound to be long and complex. Typically, there is also a lengthy delay between the time of the political decision to launch a transformation program and the time of its actual implementation. During this transitional pre-reform period, economic policies are negotiated and designed, political consensus is cemented, and key features of the institutional infrastructure are developed. In the pre-reform period actual policy reform measures are not yet implemented, and many of the basic features of the economic system are still of the centrally planned variety. However, the private sector, being clearly aware that fundamental changes are planned, begins to modify its patterns of consumption and asset holdings. Such anticipatory behavioral changes are reflected in prices, exchange rates, and rates of interest, among other important economic variables.
The purpose of this paper is to highlight some of the main forces set into motion during the pre-reform period. During that period—as illustrated by the recent experience in Czechoslovakia and, to some extent, in the U.S.S.R.—economic actions on the part of the private sector are governed by expectations of the reform rather than by the policy measures themselves. To examine this feature of the transformation process, we analyze in some detail the implications of an anticipated price reform.
Most economic reform programs designed to transform CPEs into MEs place great emphasis on the removal of subsidies that distort the prevailing price structure. It is reasonable to assume, therefore, that the private sector in anticipating the removal of subsidies expects a rise in the price level—the experience in Poland in early 1990 is a case in point. There are various reasons for such expectations. First, with lower subsidies, retail prices—typically set according to markup pricing rules—will rise so as to reflect the higher cost. Second, even with a more competitive determination of prices, it is likely that prices are somewhat less flexible downwards than upwards. Therefore, the changes in relative prices consequent on the removal of subsidies will result in a higher price level. Third, policymakers might be expected to react to the unemployment associated with the reallocation of resources by adopting expansionary measures, thereby fueling inflation.
In Section I we develop a simple model of the CPE designed to clarify the key mechanisms and effects of anticipatory behavior induced by expected price reform. This model is used in Section II to illustrate the dynamic behavior of the economy during the pre-reform period. Many of the changes occurring on the way to reform may have disruptive effects and, unless fully understood, may provide confusing signals to both the private sector and to policymakers. Our analysis identifies the key forces set in motion and thereby sheds light on the evolution of the economy on the road to reform.
Armed with this information, the model is then used to analyze the effects of expected price reform. We study in detail the anticipatory responses taking place during the pre-reform period and focus on the evolution of exchange rates, asset holdings, and aggregate demand. In this context, we pay special attention to the consequences of wage indexation, an issue that has figured prominently in recent reform programs. It is shown that a high degree of wage indexation carries with it the danger of transforming microeconomic distortions into macroeconomic difficulties. This consideration must be taken into account in the design of domestic safety nets supporting the transformation efforts.
One of the central pillars of economic policy during the process of transformation is credit policy. Section III contains an analysis of the implications of credit policies in CPEs, in which, typically, credit and financial markets are poorly developed. We highlight the various channels through which such policies exert their influence, and identify key factors responsible for the vulnerability of these economies to excessively tight credit policies.
In Section IV we examine alternative policies designed to offset some of the disruptive effects of anticipatory behavior. Special attention is given to reactive wage and interest rate policies. We show that such reactive policies require a high degree of fine-tuning, and may themselves by extremely disruptive.
In Section V we study the relation between excess liquidity (“liquidity overhang”) and the budget. The analysis, which is motivated by the recent experience in the U.S.S.R. and, to some extent, in Romania and Bulgaria, examines alternative means to eliminate excess liquidity and argues that all means involve a tax policy of one form or another. In this regard, the choice of policies depends on the “incidence of the tax,” and on efficiency considerations. We pay special attention to the interdependence between privatization, tax policies, and credibility. Section VI contains concluding remarks.
I. A Simple Model of the CPE
In this section we develop a simple model embodying pertinent features of the CPE, especially those related to imperfections in domestic financial markets. The formal model, which is designed to highlight key mechanisms of anticipatory dynamics, abstracts from many potentially important factors. Therefore, it is not intended to be fully applicable to concrete cases without some modifications. Its main conclusions, however, are likely to prevail in more realistic formulations. The model consists of two basic building blocks: the assets market and the goods market. In what follows we discuss the characteristics of these markets.2
Assets Market
In the absence of well-functioning capital markets and a fully developed system of property rights and private ownership, asset holders are assumed to hold liquid assets. These assets can be denominated in domestic currency (for example, saving accounts or cash), or in foreign currency. The latter may consist of foreign exchange or other liquid assets whose value depends directly on the exchange rate (for example, foreign cigarettes). The desired composition of this somewhat restricted portfolio of liquid assets is governed by the difference between the rates of return on these assets. Specifically, the desired ratio of domestic- to foreign-currency-denominated assets is assumed to depend on the difference between the domestic rate of interest and the expected percentage change in the nominal exchange rate. Formally, equilibrium in the asset market is represented by equation (1):
where E denotes the nominal exchange rate, defined as the price of foreign exchange in terms of domestic currency; M denotes assets denominated in domestic currency; F denotes assets denominated in foreign currency (which, in what follows, are occasionally referred to as foreign exchange); ∈ denotes the expected percentage change in the exchange rate; and im denotes the rate of interest earned by holders of domestic currency deposits. A rise in e reduces the desired ratio of domestic- to foreign-currency-denominated assets, while a rise in im raises that ratio. Assuming equality between expected and actual exchange rate changes, equation (1) can be rewritten as
where the function l depends negatively on the ratio M/EF. As indicated by equation (2), asset holders are willing to absorb a higher ratio of domestic- to foreign-currency-denominated assets only if the rate of return on domestic saving accounts, im, rises, or if the expected (equal to actual) rate of depreciation, Ė/E, falls.
Goods Market
The second key building block of the model is the goods market. The economy is assumed to produce internationally tradable goods as well as nontradable goods. We consider, first, the market for tradable goods. To set the stage for the subsequent analysis in which credit market conditions play a central role, we postulate that the level of production of tradable goods depends positively (at least for some range) on the availability of official credit. This is because credit enables firms to acquire working capital that facilitates supply, while the dependence of supply on official credit reflects the segmentation of the underdeveloped domestic credit market. Accordingly, we denote the supply of tradable goods by θyT, where yT denotes the supply of tradable goods obtained under conditions of full availability of credit, and θ denotes a coefficient, whose value ranges between zero and unity, indicating the degree of tightness in the credit market. Accordingly, a tighter control over credit policy lowers the coefficient θ, reflecting the limited ability of firms to offset the reduction in official credit through a greater reliance on alternative sources of finance. This inability, in turn, stems from the segmentation of credit markets and from the reluctance of lenders to extend credit to economic entities information about whose creditworthiness is limited. The lack of information may be particularly acute in situations where the government, prior to assuming a tighter control of credit policy, permitted enterprises to enjoy “soft budget constraints” by providing unprofitable enterprises with automatic access to credit. Where enterprise losses are automatically financed, the government is viewed as the lender of last resort and as the provider of implicit credit insurance without charging competitive risk premia; in such circumstances, information about creditworthiness is unlikely to be available, since with “free” government insurance the private sector has no incentive to collect such information.
The demand for tradable goods is assumed to depend negatively on their relative price—that is, the real exchange rate—and positively on real wages. The specification of the demand function as depending on real wages rather than on total income (including profits) reflects another key structural feature of the CPE; that is, the behavior of state enterprises as demanders is largely unrelated to profits and economic performance. Furthermore, the absence of private ownership and the lack of a developed stock market imply that the economic performance of state enterprises, as measured by profits, is not fully capitalized into private sector wealth and therefore does not exert a direct impact on demand. Reflecting these considerations, the demand for tradable goods can be written as DT(E/P, W/P), where W denotes the nominal wage; P denotes the price of the domestic (nontradable) good; and, hence, with the price of the tradable good in terms of foreign currency defined to be identically equal to unity, E/P is the real exchange rate, and W/P is the real wage (in terms of domestic goods).3
The excess supply of tradable goods represents the accumulation of foreign exchange by the private sector and the government. To simplify, we abstract from official holdings of foreign exchange and focus on the behavior of the private sector. In doing so, we assume that currency transactions are carried out at the free (or black market) exchange rate. Formally, the rate of accumulation of foreign exchange (foreign-currency-denominated assets), F, is specified by equation (3):
Thus far, we have examined the equilibrium condition in the market for internationally tradable goods, which governs the dynamics of foreign currency holdings. We consider next the market for nontradable goods and assume that the demand, DN, depends positively on the real exchange rate and on the real wage. Formally, let the demand function be DN(E/P, W/P).
The conditions governing the supply of nontradable goods depend on more detailed specific circumstances. In some cases, where productive resources are underutilized, supply adjusts to meet demand. In these “Keynesian” circumstances, demand fluctuations induced by changes in the real exchange rate and real wages result in corresponding supply responses, and are reflected in the degree of capacity utilization and unemployment. In other cases, where capacity is fully utilized, but inventories are ample, demand fluctuations are reflected in accumulation or decumulation of inventories. In yet other cases, where capacity is fully utilized and inventories do not adjust, demand fluctuations are reflected in shorter or longer delivery lags and queues.4
Which of these three patterns of adjustment in the market for nontradable goods prevails depends on structural considerations, as well as the policy stance. Relevant factors include the degree of flexibility of labor markets, labor hoarding practices, credit policies governing the holding cost of inventories of intermediate and final goods, credit availability, and the like. In practice—as demonstrated by experience in Poland during 1990—the three patterns can coexist. Accordingly, a rise in demand consequent on a rise of the real exchange rate or of the real wage results in lower unemployment and inventories, and possibly, in longer delivery lags and queues.
II. Dynamics and Expected Price Reform
In this section we analyze the dynamics of the model. Our focus on dynamics aims at illuminating economic processes set in motion during the early phases of the economic transformation program by the expectations of future policy actions. We start with a diagrammatic exposition of the model that serves to highlight its dynamic characteristics, and then examine in detail the dynamic consequences of expected price reform.
Dynamics of the Model
In analyzing the dynamics of the model, we recall that during the pre-reform phase, prices and wages are determined administratively, while official currency convertibility is absent. We assume that during that phase the rate of return on savings accounts, nominal wages, the price of domestic goods, and the money supply are determined by the central authorities. Thus, in equations (2) and (3)—which constitute the dynamic building blocks of the model—we treat im, W, P, and M as exogenously given.
As indicated by equations (2) and (3), the dynamics of the model are governed by the evolution of the nominal exchange rate, E, and the stock of foreign exchange rate, F. Figure 1 is used to describe the model. The Ė = 0 schedule shows combinations of exchange rates and foreign exchange holdings that are consistent with portfolio equilibrium as specified in equation (2). Along that schedule the rate of change of the nominal exchange rate is expected to be zero, and the prevailing ratio of domestic-to foreign-currency-denominated assets, M/EF, is willingly held. Since the nominal money supply, M, and the rate of interest paid on domestic deposits, im, are constant, the domestic currency value of foreign exchange, EF, is also constant along the Ė = 0 schedule. This schedule is negatively sloped, with an elasticity of unity, since a rise in F must be offset by an equiproportional fall in E in order to hold EF constant. A rise in foreign currency assets will be willingly held only if asset holders expect a depreciation of the domestic currency in terms of foreign exchange. Thus, as indicated by the vertical arrows in Figure 1, all points to the right of the Ė = 0 locus correspond to situations in which Ė > 0, and vice versa.
The Ḟ = 0 schedule shows the unique value of the nominal exchange rate that is consistent with no accumulation or decumulation of foreign exchange holdings by the private sector, as specified by equation (3). Since the price of domestic goods and the nominal wage rate are assumed to be given, changes in the nominal exchange rate result in equivalent changes in the real exchange rate, while the real wage (in terms of domestic goods) is unchanged. In such circumstances, there is a unique value of the nominal exchange rate that generates a demand for tradable goods that equals the domestic supply, θyT. The latter is also assumed to be given, since, for the time being, the domestic credit conditions governed by θ are unchanged. A rise in the nominal exchange rate lowers the demand for tradable goods and results in an accumulation of foreign exchange. Thus, as indicated by the horizontal arrows in Figure 1, all points above the Ḟ = 0 schedule correspond to situations in which Ḟ > 0, and vice versa.
The steady state of the model is shown by point A, at which both the nominal exchange rate and the stock of foreign assets remain constant. Any other combination of E and F would trigger dynamic changes in the directions indicated by the arrows in Figure 1. As is evident from the figure, there exists a unique path that yields a motion of these variables converging to the steady state of the system. Given the parameters of the model, any combination of E and F other than those along the boldface schedule will set in motion dynamic forces that move the economy away from the steady state. For example, if the economy were at point B, then the dynamic forces set in motion would call for a depreciation of the currency and a further accumulation of foreign exchange. The path would never converge to the steady state and would not be governed by the “fundamentals” of the model. The only path that is not explosive is the one that leads toward the steady state of the system. This path is consistent with the fundamentals: since the latter are assumed to be stationary over time, the former should not be explosive. This path is represented by the boldface schedule in Figure 1. To ensure that the economy does not follow an ever-diverging path, given its foreign currency holdings corresponding to point B, the exchange rate E will need to fall instantaneously to point C along the converging path. We restrict our analysis to such paths.
In order to gain insight into the working of the model and lay the foundations for the subsequent analysis, we consider an initial equilibrium at point A, and suppose that both nominal wages and prices rise by the same proportion. Since these changes do not affect the portfolio of assets, they do not alter the position of the Ė = 0 schedule. The rise in P, however, lowers the real exchange rate, E/P, and raises the demand for tradable goods. As a result, the private sector decumulates foreign exchange. To maintain equilibrium in the tradable goods market with constant holdings of foreign exchange, the nominal exchange rate must rise in the same proportion as the price level so as to restore the initial value of the real exchange rate. It follows that the Ḟ = 0 schedule shifts upwards to the position indicated by the Ḟ′ = 0 schedule in Figure 2. The new steady-state equilibrium is obtained at point C, and the instantaneous equilibrium is shown by point B along the boldface locus.
Dynamics of the Model Under an Exogenous Increase in Wages and Prices

The percentage depreciation of the domestic currency required by the satisfaction of initial conditions along the converging path is smaller than the percentage rise in wages and prices. The resultant decline in the real exchange rate stimulates demand for tradable goods and induces a decumulation of foreign exchange. At the same time, the initial depreciation of the currency raises the domestic currency value of foreign exchange holdings and alters portfolio composition. The new ratio of assets is willingly held only if it is accompanied by a further expected depreciation of the currency. Accordingly, along the path toward the new steady-state equilibrium, Ḟ < 0 and Ė > 0. Along the path, the percentage depreciation of the currency is smaller than the percentage decumulation of foreign exchange, and thus the domestic currency value of foreign exchange, EF, falls. It follows that in order to maintain portfolio equilibrium along the path, the expected percentage depreciation of the currency declines, and reaches zero as the economy reaches the new steady-state equilibrium at point C. In the new steady-state equilibrium the real exchange rate and the ratio M/EF return to their initial values, while the holdings of foreign exchange fall by the same proportion as the initial rise in wages and prices.
The preceding analysis illustrates the working of the model by considering the dynamic consequences of an exogenous rise in wages and prices. We build on this analysis below.
Expected Price Reform
One important feature of the transformation from a CPE to an ME is the replacement of the centrally administered prices, which are governed by large subsidies, with market-determined prices, which reflect the true production cost. The removal of subsidies is likely to result in a significant rise in the nominal prices of the subsidized goods. In what follows, we analyze the implications of an expected rise in the price level consequent on the removal of the subsidies. As noted earlier, during the first phase of the transformation process the economic actions of the private sector are governed by the expectations of such price changes, since the actual changes in prices take place only later when the price liberalization plan is implemented.
To capture key elements of the economic response to the expected price reform, we can use the simple model developed above. As an expository benchmark we assume that wage earners expect to be compensated fully for the rise in domestic prices; this assumption serves to highlight the role of wage indexation in the analysis. Accordingly, we examine the effects of an expected future rise in domestic prices accompanied by an equiproportional rise in wages.
In Figure 3 the initial pre-reform steady-state equilibrium is shown by point A, indicated by the intersection of the Ė = 0 and the Ḟ = 0 schedules. As indicated in the previous analysis, once prices and wages have risen equiproportionally, the new steady-state equilibrium is shown by point C, indicated by the intersection of the (unchanged) Ė = 0 and the Ḟ′ = 0 schedules. The converging path associated with the new equilibrium is indicated by the boldface schedule. Of course, as long as prices and wages have not changed, the dynamic forces governing the economic system are those prevailing in the pre-reform period, indicated by the arrows in Figure 3.
Effects of Expected Price Reform

In determining the economic response to the anticipated price liberalization, we first note that any abrupt change in the exchange rate results in correspondingly abrupt capital gains or losses. Consequently, asset holders attempting to benefit (or mitigate the losses) from expected sharp exchange rate changes will attempt to modify in advance the composition of their portfolios. It follows that expected abrupt changes in the exchange rate cannot occur along an equilibrium path. If on the basis of new information asset holders conclude that at some future date abrupt exchange rate changes will be necessary, then the anticipatory response of asset holders will result in an immediate change in the exchange rate. The immediate change will be of a magnitude that precludes any further expected abrupt change.
Applying this principle to the analysis in Figure 3, we note that upon receipt of the information that the price reform is expected, the domestic currency depreciates immediately, as the exchange rate jumps from point A to point B. At point B the domestic currency value of foreign exchange, EF, has risen, as has the real exchange rate, E/P. The new portfolio composition is willingly held only if the currency is expected to depreciate further, as implied by the arbitrage condition in equation (2). Likewise, the reduced demand for tradable goods consequent on the rise in the real exchange rate implies an accumulation of foreign exchange, as implied by equation (3). Accordingly, the dynamic forces operating on the economic system move the equilibrium toward point B′; the precise configuration of the dynamic path is determined by the arrows that are governed by the pre-reform situation. As is evident, in the transition between the equilibria indicated by points B and B′ the holdings of foreign exchange, as well as the nominal and real exchange rates, rise. Throughout that period the expected percentage depreciation of the currency also rises. These are the general characteristics of the period up to the actual implementation of the price reform program. Once the reform is implemented, the economic system is governed by the dynamic forces corresponding to the new situation (not drawn), and the equilibrium path becomes the boldface schedule passing through point C in Figure 3. The previous argument implies that when the price reform is implemented as expected, further abrupt changes in the nominal exchange rate are ruled out. It follows that the economy reaches point B′ precisely at the time of the rise in prices. This consideration determines the magnitude of the initial jump in the exchange rate, and is reflected in the precise position of point B.
Once the economy reaches the equilibrium at point B′, domestic prices and the wage rate rise abruptly, thereby resulting in a sharp fall in the real exchange rate. The rise in the demand for tradable goods induces a decumulation of foreign exchange. Furthermore, since at point B′ the domestic currency value of foreign exchange exceeds its corresponding steady-state equilibrium level (at points A and C), it follows that the currency is expected to depreciate further. The resulting path of foreign currency holdings and the exchange rate is portrayed by the boldface schedule. Along this path the real exchange rate rises, foreign currency holdings fall, and the domestic currency value thereof also declines. This dynamic process ends once the economy arrives at its new steady-state equilibrium. In that equilibrium, the real exchange rate, the composition of assets, and the domestic currency value of foreign exchange are the same as in the pre-reform steady-state equilibrium (point A). However, foreign currency holdings have fallen while the domestic currency has depreciated. The proportional change in both equals (in absolute value) the proportional rise in prices and wages.
So far, we have assumed that nominal wages, W, are fully indexed to the domestic price, P. Consequently, the demand for tradable goods (and thereby changes in the holdings of foreign exchange) was influenced only by changes in the real exchange rate. To examine the sensitivity of the analysis to the degree of wage indexation, it is useful to explore the implication of the opposite extreme case in which nominal wages are completely unindexed. Our interest in wage indexation stems from the fact that recent economic reform programs have paid much attention to the appropriate degree of wage indexation, reflecting interest in the macroeconomic and income distribution consequences of the price reform.
Under circumstances in which nominal wages are fixed (and, hence, unindexed), the expected rise in domestic prices lowers post-reform expected real wages. This, in turn, lowers the post-reform demand for tradable goods, DT. To stimulate the demand for tradable goods to the level prevailing before the fall in real wages, the real exchange rate would need to fall. It follows that the displaced Ḟ = 0 schedule in Figure 3 must lie below the Ḟ′ = 0 schedule (along which the real exchange rate equals its pre-reform level). However, since the post-reform Ḟ = 0 schedule is displaced upward, the qualitative characteristics of the previous analysis remain intact.5
As is evident, the dynamics of the system depend critically on the degree of wage indexation. In particular, the evolution of the nominal exchange rate during the transition period may have profound implications for the inflationary consequences of the price reform. The higher the degree of wage indexation, the larger the depreciation of the currency, and the greater are the inflationary pressures. As argued in subsequent sections, these pressures may result in a credit crunch, reducing working capital and negatively affecting the supply of output. It follows that a high degree of wage indexation carries with it the danger of transforming a microeconomic problem (associated with the subsidized prices) into a macroeconomic problem (associated with a flare-up of inflation). Thus, the more effective is the domestic safety net designed to protect wage earners, the more likely it is that macroeconomic problems will ensue. There is, therefore, a trade-off between the degree of domestic political support for the economic transformation program (a support that is enhanced by high wage indexation) and the degree of price and output stability during the transition period.
Our analysis of the effects of an expected price reform can now be extended to examine the effects on the market for nontradable goods. We first recall from the analysis in Figure 3 that with wages fully indexed to domestic prices, the real exchange rate rises throughout the period of transition toward price reform. It then drops sharply once the reform is implemented, and subsequently it rises back toward its initial pre-reform level. These changes in the real exchange rate result in an initial rise in the demand for nontradable goods, followed by a sharp decline occurring at the time the price reform is implemented. During the subsequent period the demand recovers gradually until it reaches its pre-reform level. Depending on the pattern of adjustment in the market for nontradable goods, these demand changes induce corresponding fluctuations in employment, capacity utilization, and so on. To simplify matters, consider the situation in which the supply of nontradable goods (and thereby the level of employment and capacity utilization) adjusts to satisfy the demand. Under these circumstances, employment rises during the initial phase; it then suffers a sharp decline once the price reform is implemented. Subsequently, employment recovers gradually until it returns to its initial pre-reform level.
If the degree of wage indexation is less than complete, then it can be verified that the initial rise in the real exchange rate and the increase in the level of employment are less pronounced, their subsequent fall upon implementation of the price reform is more pronounced, and their recovery during the subsequent period is incomplete. It follows that the levels of employment and capacity utilization obtained with a low degree of wage indexation are lower than the corresponding levels obtained with a high degree of wage indexation. A parallel analysis applies to the evolution of inventories and queues if, in the face of fluctuating demand, these are the dominant forms of adjustment in the market for nontradable goods.
The foregoing analysis of price reform presumed that the rise in prices consequent on the removal of subsidies is determined by the free operation of market forces. In practice, as illustrated by experience in Poland and Romania, especially in the area of energy pricing, governments have attempted to avoid an excessively large price shock by adopting a strategy of administered pricing. This strategy permits the spreading of what otherwise would have been a once-and-for-all price rise over a lengthy period of time. However, our previous analysis of anticipatory behavior suggests that some of the benefits from administratively spreading the price rise over time may be illusory. The private sector, being familiar with the administered pricing strategy, is likely to modify its behavior in anticipation of future price rises. The resulting pattern of adjustment may be much less smooth than the one envisaged by the designers of the strategy. The possible disruptions stemming from such anticipatory behavior point to the benefits of an early replacement of administered pricing by market-determined pricing. Such a replacement, which could be followed by an eventual dismantling of the administered-pricing apparatus, would provide a useful signal of the commitment of the government to the program of economic transformation and restructuring.6
III. Credit Policy
The analysis in the previous section focused on the implications of an anticipated future price reform. To simplify matters, we examined the “pure” case in which prices are expected to rise, owing, for example, to a removal of subsidies. We have not incorporated into the analysis anticipatory responses to other policy measures that are likely to be an integral part of the policy reform package. Specifically, the restoration of credit control is viewed as one of the central pillars of economic policy programs aimed at transforming CPEs into PCPEs. Indeed, tight credit control is seen as one of the most important measures necessary to combat inflation and establish credibility. Therefore, in anticipating future price reform, the private sector is likely to assume that the removal of subsidies is accompanied by a tight credit policy. In this section we analyze the mechanisms through which credit policy influences the economy.7 To gain insight, we first examine another pure case in which credit policy is taken in isolation, rather than in conjunction with the expected removal of subsidies.
The main rationale behind the use of restrictive credit policy to combat inflation is well known; it is grounded in theory and is substantiated by experience. The conventional channel through which credit contraction influences the economic system is its restraining effect on aggregate demand. However, as was indicated in Section I, in economies that are not yet fully developed MEs, official credit may have strong effects on aggregate supply.
Consider the effect of a contractionary credit policy. This policy influences the economy through three channels: the supply of output, the demand for output, and portfolio choice. Starting with the supply side, we note that the credit crunch reduces working capital and provokes a decline in output. The reduced supply of tradable goods results in a depreciation of the currency, upward pressures on the prices of tradable goods and, thereby, on the general price level.8 These pressures are more pronounced the higher the degree of wage indexation. Moreover, higher wages and prices increase the need for working capital and aggravate the credit crunch. It follows that the severity of the credit crunch increases with the degree of wage indexation. In this example, credit contraction (in particular, under conditions of wage indexation) results in stagflation: it reduces output and exerts inflationary pressures.
The negative supply-side effects may be of special relevance for PCPEs. As emphasized earlier, with segmented and underdeveloped financial markets, the reduction in working capital induced by an official credit contraction has adverse implications for the enterprise sector. Firms whose access to other sources of finance is limited will attempt to mitigate the shortage of working capital by relying on interenterprise credit. An expansion of the interenterprise credit network may reduce the severity of the credit crunch on output in the short run, but is unlikely to offset it completely. Furthermore, as discussed below, an excessive reliance on an interenterprise credit network has profound macroeconomic consequences for both the effectiveness of monetary policy and the efficiency of resource allocation.
We consider next the mechanisms through which the credit crunch affects demand. First, firms whose access to the credit market is limited attempt to build up working capital both by running down inventories of inputs and final goods and by reducing demand for the products of other firms. Second, to the extent that the credit crunch raises interest rates, it contributes further to the reduction in demand.
The combined effect of the changes in supply and demand depends on their relative magnitudes. If the net effect of the credit crunch is dominated by the fall in supply, then the qualitative results of our earlier analysis of the negative supply-side effects hold. If, however, the reduction in demand more than offsets the fall in supply (with proper allowance given to inventory change), then the contraction in official credit induces an instantaneous appreciation of the currency.9
The analysis, thus far, has focused on the effects of credit policy on the market for internationally tradable goods. As a result, the economic consequences of that policy depended entirely on whether it generated excess demand or supply. Parallel to its effect on the market for internationally tradable goods, the credit crunch also influences the market for nontradable goods through its effect on the demand and supply of these goods. As in the previous analysis, the supply effects may be distributed among changes in output and capacity utilization, changes in inventories, and changes in queues.
The third mechanism through which credit policy affects the economy is through its effect on portfolio choice, especially if the credit contraction is associated with a rise in the deposit interest rate. It can be verified that, in and of itself, this factor provokes an instantaneous appreciation of the domestic currency.10
The foregoing discussion highlighted the three main factors that need to be taken into account in the analysis of the economic consequences of credit policy: the supply effects, the demand effects, and the portfolio effects. Which of the three effects dominates depends, of course, on the specific circumstances. Furthermore, the relative importance of these three effects will vary over time. Specifically, effects associated with changes in inventory holdings are by their nature more pronounced in the short run; they play, therefore, a more important role immediately after the implementation of the credit crunch. Other effects, such as those associated with changes in financial portfolios, may prevail for a longer period. Since the effects of credit policy on the economy may change significantly over time, close attention should be given to its dynamic consequences.
From the discussion of the evolution of the economy following the credit squeeze, it should be evident that a similar analysis applies to the effects of an expected future credit crunch. In that case, market participants will respond immediately to the anticipated future change in credit policy. As a result, the exchange rate, foreign currency holdings, and other key economic variables will change, even though no policy action has yet taken place. The model can be readily used to illustrate the dynamics induced by these anticipatory phenomena. Such dynamic considerations are of special relevance for PCPEs, in which the depth and breadth of financial markets, as well as the volume and nature of interenterprise credit, change over time.
A credit crunch resulting in a sharp rise in both deposit and loan rates of interest may be especially damaging under the institutional environment prevailing in PCPEs. In such an environment, the increased fragility of the banking system (induced by the rise in deposit rates) superimposed on the financial vulnerability of enterprises (induced by the rise in loan rates) puts significant strains on the economic system. These strains may be especially severe in these economies due to the elaborate network of interfirm credit and the underdeveloped financial system. In such circumstances, financial difficulties of one firm may spread to other firms through the credit network.
This interdependence of firms linked through the network of interfirm credit impedes the effectiveness of the signals provided by the price system for an efficient allocation of resources. In MEs with well-functioning markets, the price mechanism helps to distinguish between firms that should go out of business and those that should survive. This important allocative function of the price mechanism is impaired in PCPEs, since interdependence among enterprises makes it difficult to distinguish between “good” and “bad” firms. Thus, a credit crunch designed to reduce macroeconomic distortions may give rise to further microeconomic distortions.11
IV. The Dangers of Fine-Tuning
The previous sections examined the implications of anticipatory reactions to price reform and the implications of credit policies. The two analyses have been conducted separately so as to highlight the dynamic processes set in motion in each of the pure cases. In practice, the expected rise in prices consequent on the removal of subsidies—designed to reduce microeconomic distortions—is likely to be accompanied by current or expected future credit policies—designed to prevent a flare-up of macroeconomic distortions. The two pure cases provide the ingredients relevant for the analysis of the more complex case in which both phenomena appear simultaneously.
Rather than going through the tedious procedure of combining the two pure cases, we turn next to an examination of some specific policy responses that can be used to mitigate, or even offset, some of the undesirable dynamic consequences that were illustrated by the pure cases. In this context, we focus on wage and interest rate policies. The results of this examination demonstrate the difficulties associated with fine-tuning.
Consider, for example, the effect of a rise in the price of nontradable goods. As shown in the previous analysis, such a price rise induces an immediate depreciation of the domestic currency, followed by a transition period during which the currency continues to depreciate, while foreign currency holdings decline (see Figure 2). Is there a wage policy that would prevent this adjustment while keeping the system at the initial equilibrium? In principle, the rise in demand for tradable goods induced by the real appreciation of the currency can be offset by an appropriate fall in the real wage. Thus, if the real wage were to fall in this fashion, the system would remain at its initial equilibrium, and the cost of adjustment could be avoided.12 However, such a decline in the real wage aggravates the reduction in demand for nontradable goods induced by the real appreciation of the currency. As a result, the output of nontradable goods falls, inventories of unsold goods accumulate, and a recession ensues.
The same principles apply with greater force to the case in which the rise in prices has not yet taken place but is expected to occur in the future (see Figure 3). In that case, the real wage policy necessary to maintain external balance will need to change continuously so as to offset the dynamics of the system. However, as with the previous analysis, the maintenance of external balances induces a recession in the market for nontradable goods.
The complexity of the policy attempting to offset the dynamic evolution of the system—and the extraordinary degree of fine-tuning that such a policy necessitates—is not specific to the above example in which the burden of adjustment falls on real wages. Rather, it is a general characteristic of policy responses designed to offset anticipatory dynamics. For example, the monetary authorities may attempt to offset the effects of the anticipated price rise by altering the interest rate paid on deposits and, thereby, affecting portfolio balance. As in the previous analysis, it can be verified that, to be successful in offsetting the undesirable consequences of anticipatory dynamics, the monetary authorities need to adopt an extremely complex fine-tuning interest rate strategy.13
Using an interest rate policy to offset the dynamics of anticipatory adjustment may be especially tempting, since, in principle, the rate of interest can be modified in short intervals. It can be shown, however, that such a policy cannot be sustainable and, in fact, is likely to be explosive. The maintenance of initial equilibrium requires ever-rising deposit rates, which ultimately will put the viability of the banking system in question. In addition, the rise in deposit rates may exert upward pressures on loan rates and thereby put the viability of enterprises in question. Both of these developments may undermine the credibility of policymakers as market participants lose confidence in the viability of the entire policy strategy. Indeed, one of the main difficulties faced by policymakers in PCPEs is the possible lack of credibility of announced policy intentions. In such circumstances, a policy strategy that relies on continuously changing policy actions and, as in this particular example, on continuously tightening credit, is unlikely to contribute to the buildup of credibility.
This last conclusion is of special relevance, since it limits somewhat the force of the argument that a tight credit policy contributes to the buildup of credibility through demonstrating the resolve of policymakers. While, as a general guide, especially when implemented in the context of a comprehensive economic program, this argument makes a lot of sense, the drawbacks associated with an excessive reliance on tight credit may, in fact, erode credibility. The negative supply-side effects of a credit crunch in PCPEs reflect the infancy of credit markets in such economies. A key implication is that to restore the conventional potency of credit policy, efforts should be directed at financial market reform, aimed at the development of domestic credit markets, coupled with the development of appropriate regulatory and supervisory systems.
V. Liquidity Overhang and the Budget
Our analysis of the process of transformation from CPE to PCPE focused on the early phases of the transition during which the expected removal of subsidies to consumer and intermediate goods entails expectations of future price rises. These expectations may arise from the observation that the removal of subsidies often results in sizable price jumps, as illustrated by recent experience in Poland. They may also be grounded in the belief that the economy has a liquidity overhang. For our purposes, a liquidity overhang can be defined as a situation in which price liberalization and the removal of subsidies bring about a rise in the measured average price level. In addition to the direct effects of the removal of subsidies, the measured price level rises because elements of cost (reflected in queues and delivery lags), which were not included in measured prices before the reform, become explicit afterwards.
There are essentially three mechanisms to reduce a liquidity overhang: first, by increasing the attractiveness of domestic liquid assets through a rise in the rate of interest paid on domestic currency deposits; second, through a rise in prices associated with the price liberalization; and, third, through a reduction in liquidity. The first mechanism raises the demand for real liquid assets, while the second and third both lower the real supply of such assets. These three mechanisms have been emphasized, in varying degrees, in connection with the debate on the various means of reducing the liquidity overhang in the U.S.S.R., and, to some extent, in Romania and Bulgaria.
In analyzing the first of these three mechanisms, we note that a rise in the deposit rate, especially in circumstances prevailing in PCPEs, may have adverse implications for the government budget. In such economies the banking system is “owned” to a large extent by the government. Therefore, a rise in the rate of interest paid by banks is a drain on the budget. In fact, in many respects, bank deposits may be regarded as public debt, and interest on deposits may be viewed as public debt service. From this perspective, credit and budget policies are closely linked to each other, and the rise in the deposit rate will need to be financed through new taxes. The budgetary drain induced by the higher deposit rate will be greater, the lower is the interest elasticity of the demand for real liquid assets. The effectiveness of this mechanism of alleviating the liquidity overhang will depend on the capacity of the tax system to generate the necessary tax revenue, and on the distributive and efficiency implications of the associated “incidence of the tax.” Furthermore, an assessment of the desirability of this mechanism will need to take into account the effects of the deteriorated budget on credibility.
The second mechanism for eliminating the liquidity overhang—through a rise in the measured price level—was analyzed implicitly in previous sections. There, the anticipatory behavior of the private sector was based on the assumption that the price reform results in a price rise. For concreteness, in terms of our notation, we identify the measured price level with P. Although we will not elaborate further on this mechanism, it is worth noting that the price rise is a tax on the real value of domestic liquid assets. Therefore, an evaluation of this mechanism also depends on the specific incidence of the tax and on its effects on political support, on the efficiency of resource allocation, and on policy credibility. These effects depend, in turn, on the capacity of the government to avoid the transformation of what in principle should be a once-and-for-all price rise into an inflation spiral.
Consider next the third possible mechanism for the elimination of the liquidity overhang—a reduction in liquidity. In principle, the excess liquidity could be reduced either through direct confiscation (a monetary reform), or through open market sales of assets. The adoption of a monetary reform may be highly effective in bringing about a rapid elimination of the overhang. Indeed, there have been several historical episodes in which monetary reforms were implemented successfully, especially in the context of a comprehensive program dealing with hyperinflation. Since, however, the incidence of the tax associated with a monetary reform is not distributed evenly across the population, it may erode the political support necessary for a successful implementation, and may require appropriate incomes policies designed to provide social safety nets and to secure political support. Furthermore, the direction of the effects of this confiscatory policy (along with the accompanying incomes policies) on economic efficiency and on credibility is not unambiguous.
The elimination of liquidity overhang through open market sales is also subject to some limitations. In PCPEs the possibility of conducting open market sales is limited by the absence of conventional financial instruments and by the underdevelopment of capital markets. However, in such economies, the government owns a large portion of existing assets and, in many cases, wishes to undertake a privatization program. In such circumstances, the excess liquidity can be absorbed through open market sales of the housing sector and of state enterprises. In addition, the increased size of the market economy resulting from the privatization process may increase the demand for liquidity and reduce the size of the overhang as transactions shift from the barter to the monetized sector.
The difficulties in designing an effective privatization program are well known.14 They include the problems of establishing a fair market price for an enterprise without the help of a well-functioning marketplace, developing the legal infrastructure necessary for the effective use of entrepreneurial drive, developing domestic credit and financial markets necessary for intermediation, and establishing mechanisms dealing with the redistribution of rents and the potential for corruption. In addition to these and other difficulties associated with the incidence of the tax, privatization has profound implications for the budget. On the one hand, sales of state enterprises generate (nonrecurring) revenue (which, however, cannot be spent, because, otherwise, a new liquidity overhang would result); on the other hand, the transfer of income-producing assets to the private sector results in a (recurring) loss of future revenue. To make up for this lost revenue, the government needs to find a new source of recurring income.15
In searching for a new source of recurring income, the government will be tempted to levy new (previously unannounced) taxes on the enterprises just sold to the private sector. Such a strategy would, however, be counterproductive. In setting their bids for state enterprises, potential buyers will take into account the possibility that the government will be tempted to raise taxes. Such anticipations tend to lower the market price of state enterprises, reduce the proceeds from privatization, and leave the liquidity overhang problem unsolved. To prevent the erosion of privatization proceeds, the government must provide reliable and believable signals that such “surprise” taxes will not be levied. To produce such credible signals, the government must demonstrate its capacity and unequivocal commitment to tap new sources of tax revenue. These new sources of tax revenue must cover the entire loss of recurrent revenue resulting from the privatization program. Thus, for a privatization program to be implemented effectively, the government must levy new taxes on entities other than the newly privatized enterprises.
The foregoing analysis of the various means to eliminate liquidity overhang through a reduction in real liquidity reveals that in all cases the private sector ends up being taxed by the full amount of the overhang. In deciding on the policy response for the liquidity overhang, the government must recognize that the various solutions differ in the incidence of the taxes that they entail.16
Additional important factors that should be taken into account in choosing among the various solutions to the liquidity overhang problem include their differential effects on the efficiency of resource allocation and on the reputation and credibility of the government. The beneficial effects of privatization on the efficiency of resource allocation can be significant if the privatization of state enterprises and the housing sector provides incentives for higher productivity and better maintenance of the capital stock. Such benefits are especially pronounced in circumstances where domestic capital markets are in their infancy. Indeed, in most CPEs and PCPEs these markets are underdeveloped, segmented, and lack the know-how necessary for their effectiveness. In this regard, the opening of the economy to foreign investment can be highly beneficial. In addition to providing financial and managerial capital, privatization programs that encourage direct foreign participation can be useful in providing access to international capital markets. Foreign investors bring with them know-how, contacts, and information. Their presence and active participation yield the added benefit of improving the functioning of domestic capital markets.
The preceding discussion suggests that the government could announce its intention to accompany the price reform with one of the three types of mechanisms discussed above. If fully credible, the announcement of such a policy package would eliminate the anticipatory dynamics and make it unnecessary to resort to costly policies of fine-tuning during the transition period. Full credibility is the sine qua non for the success of this strategy. It must be recognized, however, that as a general rule governments finding themselves on the road from CPE to PCPE do not possess the full details of their future economic programs. Furthermore, the private sector will lack experience with the operation of markets in transition. In addition, policymakers and the private sector alike will be keenly aware that other experiences of economic transformation (especially during the early phases) have occasionally been associated with a rise in prices and departures from previously planned policies. Against this background, it is very likely that government pronouncements are not fully credible. Thus, it is improbable that the government can prevent the anticipatory dynamics during the transition period unless it resorts to costly fine-tuning. Furthermore, to achieve credibility, the government may need to adopt front-loaded measures. Therefore, in practice, the government may not be able to delay adoption of the accompanying measures until the date of the price liberalization. These considerations suggest that the transitional pre-reform period characterizing the early stages of the transformation from CPE to PCPE should be as short as possible.
VI. Concluding Remarks
The transformation of CPEs into MEs is a long and complex process. Invariably, the early phases of the transformation involve a great degree of uncertainty and vulnerability. During the early phases, the old system has collapsed, but the new system is not yet in place. The “rules of the game” are still vague, and the detailed policy course unknown. While the policy strategy is debated, the economic behavior of households and investors is governed by expectations. This paper deals with issues arising during the early stages of the transformation of CPEs, and identifies key factors governing its evolution.
An important theme in the analysis is that observed patterns of exchange rates, asset holdings, and economic activity in general reflect both economic policies already in place and policy measures that are expected to be implemented in the future. The anticipatory character of economic behavior is of special relevance in the early stages of the transformation process. During these stages there are expectations of comprehensive future policy actions, while policy measures actually taken are few and limited in scope. To highlight this anticipatory feature, we developed a simple model in which the behavior of asset holders plays a critical role. The model was used to analyze the consequences of expected price liberalization. We demonstrated how the expectations of future price reform induce a depreciation of the currency, sharp changes in the current account of the balance of payments (driven by defensive actions on the part of asset holders), and corresponding changes in economic activity. In this context, we paid special attention to the role of wage indexation and showed that a high degree of wage indexation carries with it the danger of transforming a microeconomic problem (associated with subsidized prices) into a macroeconomic problem (associated with a flare-up of inflation).
A major focus of our analysis was the role of credit markets and the effects of credit policies. In this regard, we noted that the special circumstances prevailing in these economies include lack of depth and breadth of financial markets and a complex network of interenterprise debt. The critical dependence of firms on working capital and the lack of an information system necessary to assess risk and creditworthiness and, more generally, to distinguish between good and bad firms complicate the conduct and effectiveness of credit policy. The analysis illustrated the pitfalls of transplanting policies appropriate for market economies into an environment lacking the basic institutional infrastructure—including regulatory and supervisory systems—necessary for the operation of credit and financial markets. This consideration underscores the benefits of an early development of domestic credit and financial markets, as well as the desirability of finding ways to “clean” the balance sheets of enterprises and banks by expunging bad debts.
The benefits from trade liberalization also depend on the quality of capital markets. Trade liberalization provides the economy with the right price signals. Exposure to world prices helps to demonopolize the economy, enhance competition, and improve the allocation of resources. However, in adjusting to the removal of protection, even good and economically viable firms may require credit. The adoption of hard budget constraints eliminates the automatic financing of enterprises’ deficits by the government. Without sufficient access to capital markets such good firms may be forced out of business, thereby reducing the benefits from trade liberalization. Moreover, in attempting to protect themselves, the good but endangered enterprises may be tempted to join the bad and economically nonviable enterprises in lobbying against trade liberalization, thereby reducing the likelihood that liberalization will be adopted. These considerations imply that the benefits from, and support for, trade liberalization can be significantly enhanced by an early development of domestic capital markets.
The dynamic evolution of the economy during the early stages of transformation is complicated, costly, and disruptive. The profound changes in the rules of the game and in the policy regime may result in fundamental changes in the behavioral patterns of market participants. Policymakers may be tempted to use an arsenal of policy instruments in attempts to offset disruptive changes in key economic variables. To examine the consequences of such efforts, we analyzed the implications of wage policies as well as interest rate policies designed to offset the anticipatory changes. We showed that, to be successful, the authorities must adopt an extremely complex fine-tuning strategy of policy response. The lack of full credibility of announced policies, superimposed on infant credit markets, increases the likelihood and costs of policy mistakes. We therefore rejected the fine-tuning strategy and emphasized the desirability of a quick implementation of price reform.
In circumstances of a liquidity overhang, the removal of subsidies associated with price reform induces a significant jump in the price level. We examined alternative means by which such a liquidity overhang can be alleviated. In addition to a rise in prices, such means include a rise in interest rates and a fall in the nominal money stock. We showed that all of these measures involve taxation of one form or another. The choice among the various alternatives depends on (1) the capacity of the tax system to generate revenue, (2) the distributive and efficiency implications of the incidence of the tax, (3) its effects on political support, and (4) policy credibility. In this context, our analysis examined the consequences of privatization as a means to absorb excess liquidity. Aside, of course, from the obvious efficiency benefits that private ownership entails, we showed that to be fully effective privatization must be accompanied by increased taxes in the amount of the liquidity overhang. In the absence of such increased tax revenue, privatization results in medium-term budget deficits and a rise in public debt. This consideration underscores the benefits from an early development of an effective tax system.
Our analysis illustrated the interdependence among price reform, trade liberalization, reform of financial and capital markets, economic stabilization, and budget and tax reform. Obviously, the adoption of a comprehensive reform program encompassing the entire economic system is desirable. Indeed, macroeconomic and structural reform measures introduced simultaneously are likely to reinforce each other, provide confidence and momentum, and reduce the risk that the process be reversed. The enhanced confidence would lengthen the planning horizon of savers, investors, and enterprises, stimulate domestic and foreign investment, and contribute to the credibility of the transformation process.
In practice, however, it is unlikely that the prevailing socioeconomic conditions can always generate the political support necessary for the adoption of a rapid, comprehensive, and all-inclusive reform. Frequently, choices need to be made as to the appropriate pace and sequence of reform measures. In this regard, there is no blueprint. Indeed, as indicated at the beginning of this paper, the optimal pace and sequence of reform measures depend on circumstances that differ across countries. These circumstances reflect diversities of historical backgrounds, economic, legal, and political institutions, entrepreneurial traditions, as well as attitudes toward the role of markets and incentives. Such disparate circumstances imply that the economic reform programs of different countries may differ in their areas of vulnerability. For example, one society may be highly sensitive to the effects of reform on the level of employment, while another may be especially susceptible to the prices of foodstuffs. Likewise, one society may be highly sensitive to the effects of a reform of income distribution, while another may wish to protect the real value of private sector savings. Such differences in sensitivities may be reflected in the choice of the sequencing of reform measures, as well as in the characteristics of safety nets.
In choosing among alternative safety nets, one should be aware that there is no way to protect all segments of society. A comprehensive reform program must involve sacrifices by a substantial share of the population. Furthermore, in designing the mechanism through which the safety net is effected, one should avoid as much as possible the introduction of new distortions. In this regard, the safety nets should not interfere with the incentives to work, save, and invest, nor should they tamper with monetary and exchange rate policies. Rather, they should be allowed for in the budget and effected through income transfers.
Although different countries may wish to choose different sequences of reform measures, in many cases such a choice may not be available if policy options are overtaken by events. In view of the fast-changing circumstances in these economies, it may well be preferable to adopt a timely, albeit somewhat imperfect, comprehensive reform program than to search for the perfect program, encompassing a fine-tuned sequence of policy measures. The danger of a lengthy probe for the perfect sequence under conditions of fast-changing circumstances is that, once implemented, the program may turn out to be outdated and irrelevant.
Whatever the choice of sequence, the early steps must reflect the notion that a necessary condition for a successful transformation is its credibility. A well-designed economic program will not be effective if it is not credible. In this regard, a crucial early step must be a fundamental change in the mentality and attitude of the policymaker. The policymaker should recognize the limitations of discretionary policies, the virtues of transparent and simple rules that encourage entrepreneurial pursuits, and, above all, should be cognizant of the fact that policy actions (and inaction) convey powerful signals to the marketplace. In this regard, the early steps must be meaningful and bold. They must convey the credible message that the government’s support for the economic reform process is absolute, that the government is aware that some setbacks along the path are inevitable, but, at the same time, that postponements and reversals of policy commitments would entail a very high political cost. Such a message is likely to reduce the degree of uncertainty, increase the confidence of consumers, lengthen the time horizon over which economic plans are made, stimulate domestic and foreign investment, and contribute to the success of the economic transformation process.

Recently, there has been a flurry of interest in issues related to the transformation of centrally planned economies. Examples of recent, relevant literature are Calvo (1990), Dornbusch (1990), Fischer and Gelb (1990), Klaus (1991), Kornai (1990), Lipton and Sachs (1990a), Marer (1990), McKinnon (1991), Portes (1990), and Wolf (1990).
The structure of the model is related to the one developed in Calvo and Rodriguez (1977) and Frenkel and Rodriguez (1982).
It would be more appropriate to specify the demand function as depending on the wage bill rather than the wage rate. The latter is used for the sake of simplicity. For the present purposes, however, this simplification does not alter the main thrust of the analysis. Similar reasoning applies to the exclusion of other relevant variables like interest rates, real balances, and other assets.
The difference between the patterns of adjustment in the markets for tradable and nontradable goods is introduced to highlight the diversity of adjustment mechanisms that are called for in the absence of full price flexibility. In our specification the flexibility of the (black) market exchange rate captures the anticipatory feature of the pre-reform period. Thereby, this flexibility introduces a mechanism of adjustment in the market for tradable goods that is absent in the domestic goods market, and underlies the assumption that output in the tradable goods sector is not governed by domestic demand.
To verify this result, we note that, using the homogeneity postulate, the demand for tradable goods (see equation (3)) can equivalently be specified as a function of P/W and E/W. Without wage indexation, the excess demand for tradable goods induced by the expected rise in the domestic price can be eliminated by an appropriate rise in E. Thus, in that case, once the domestic price rises, the Ḟ = 0 schedule is displaced upwards. This upward displacement reflects the implicit gross substitution assumption. A similar analysis applies for partial wage indexation. The higher the degree of wage indexation, the larger the upward displacement of the Ḟ = 0 schedule.
In addition to these considerations, it is noteworthy that administered price changes are unlikely to deal effectively with the huge distortions in relative prices that are so prevalent in CPEs and PCPEs. Identification and correction of such relative price distortions will need to rely on market forces.
For a related discussion on the role of credit policy, see Calvo (1990). For a broader analysis on the role that credit markets play in the economic transformation process, see Calvo and Frenkel (1991).
In terms of the model, the credit contraction reduces the credit coefficient, θ, and results in lower output of tradable goods. The reduced supply of tradable goods, in and of itself, results in an upward displacement of the Ḟ = 0 schedule in Figure 2 to the position indicated by the Ḟ′ = 0 schedule. Consequently, the domestic currency depreciates instantaneously, and the initial equilibrium shifts from point A to point B in Figure 2. Thereafter, the nominal exchange rate and the holdings of foreign exchange move along the boldface schedule toward point C. During the transition, the currency continues to depreciate in nominal and real terms, while the private holdings of foreign exchange decline, in terms of both foreign and domestic currency.
In terms of the model, if the fall in supply dominates the reduced demand, then the Ḟ = 0 schedule shifts upwards, and the dynamic analysis follows along the lines indicated in the previous footnote. If, however, the fall in demand exceeds the reduction in supply, then the Ḟ = 0 schedule shifts downwards, and the currency appreciates instantaneously. This is followed by a transition period during which the currency continues to appreciate, thereby exerting downward pressures on prices. Throughout, the holdings of foreign exchange (whether measured in terms of domestic or foreign currency) rise.
In terms of the model, a rise in im raises the desired ratio of domestic to foreign currency in private sector portfolios and induces a downward displacement of the Ė = 0 schedule. It can be verified that the instantaneous appreciation of the domestic currency is followed by a transition during which the currency depreciates to its original level, while foreign currency holdings decline.
For a detailed analysis of the role that credit markets play in distinguishing between “good” and “bad” firms in the context of economic transformation, see Calvo and Frenkel (1991).
In terms of the analysis in Figure 2, a fall in the real wage, W/P, compensating for the real appreciation of the currency (that is, the fall in E/P), keeps the Ḟ = 0 schedule in Figure 2 intact. Hence, the initial values of the nominal exchange rate and of foreign currency holdings do not change, and the initial equilibrium prevails.
In terms of our model, the fine-tuning policy of a rise in the deposit rate, im, induces a downward displacement of the Ė = 0 schedule in Figure 3, and sets in motion a new equilibrium path. The complexity of a fine-tuning policy would be enhanced once one allows for the possibility that the sharp change in the economic regime associated with the economic transformation process induces changes in the behavioral patterns of economic agents.
Examples of recent analysis of issues arising in privatization efforts in PCPEs are Frydman and Rapaczynski (1990) and Lipton and Sachs (1990b). For an examination of these and other privatization schemes, see Borensztein and Kumar (1991; this issue).
In calculating the full budgetary implications of absorbing liquidity through asset sales, allowance should also be made for the saving on the interest payments on the savings accounts in which the liquid assets were held.
Similar considerations apply to proposals to absorb the liquidity overhang by sales of housing. Unless the government reduces significantly the rent control provisions (representing thereby a specific incidence of the tax), there will not be much incentive for tenants who pay ridiculously low rents to purchase high-price housing.
