IV. The 1995 Pension Reform 1/

1. Introduction

Pension systems in many industrial countries need to be restructured. The case for reform documented in numerous studies rests upon two pillars: (i) the generosity of a pension system, financed, at least in part, through high payroll contributions that place a distortionary burden on labor markets, and (ii) the prospect of a deterioration in key demographic ratios, which would put additional strain on pension system finances. On both counts Italy had long been singled out as country whose pension system was in dire need of reform.

At the time of the 1994 Article IV consultation, the staff discussed the need for pension reform and evaluated the impact of alternative reform proposals (SM/95/48, Supp. 1). A fundamental reform of the system was introduced in mid-1995 and a new pension law (Law No. 335) was passed by Parliament. The law modifies substantially the mechanism for computing retirement benefits; merges the old-age and seniority pension schemes into a single one that still allows, but also penalizes, early retirement; and introduces measures aimed at closing loopholes that had effectively narrowed the base on which contributions were computed. This chapter summarizes the main features of the new system and evaluates to what extent the reform addresses the two problems mentioned above.

The chapter argues that the reform has put in place a system with much improved long-run properties: actuarial soundness; an incentive, albeit modest, to postpone retirement; a closer link between contributions and benefits; and a less heterogeneous treatment of different categories of workers. These properties, together with tighter eligibility criteria for survivors’ pensions, will eventually lower the ratio of pensions to GDP. The new law also improves on the previous system by making it more transparent and casting it in terms of a clear set of parameters which can be modified without need for a full-fledged reform. Nevertheless, the law leaves in place a comparatively generous system of benefits financed by high contribution rates for dependent workers and does not address the problem posed by the demographic transition in prospect during the first half of the next century.

The chapter is organized as follows: section 2 discusses briefly the need to amend the pension system in Italy prior to the 1995 reform; section 3 describes the main features of the new system; section 4 examines its long-run properties; section 5 discusses the medium-term effects of the reform; and section 6 puts forward some conclusions. Three appendices contain some supporting technical material.

2. The case for reform

As has been widely documented, almost all industrial countries are likely to experience a relatively rapid deterioration in elderly dependency ratios in the first half of the next century, with complex social and economic consequences. To the extent that public pension systems in most of these countries operate on a pay-as-you-go basis, the evolution of the dependency ratio will imply a similar profile for pension outlays as a percentage of GDP. The result will be an increased strain on the public finances of these countries. Most studies of the effects of the demographic transition on industrial countries’ fiscal accounts tend to coincide in their recommendations: benefits must be reduced and eligibility criteria tightened. The magnitude and scope of the adjustment needed, however, will depend on country-specific existing arrangements and financial pressures. 1/

The case for reform has long been apparent in Italy. 2/ On the one hand, the Italian pensions system is particularly onerous and has been posing a heavy burden on one of the most strained public finances among industrial countries (Table 1 and Chart 1). On the other hand, Italy’s elderly dependency ratio is expected to increase faster, or reach a higher peak, than in most industrial countries during the first half of the next century--Chart 2. 3/ The previous reform of the pension system by the Amato government in 1992 introduced important measures aimed at preventing an explosion in pension-related outlays, but did not fully address these problems: 4/ contribution rates remained high and, given the vulnerability of the existing system (henceforth referred to as the Amato system) to demographic dynamics, its finances would have not been able to cope with the expected deterioration in key demographic ratios. A study by Antichi (1995) shows that as a result of the substantial increase expected in the elderly dependency ratio in Italy by the years 2030-50, equilibrium contribution rates would have risen to economically unfeasible levels had the Amato system been operational.

Despite its large scale, the demographic aspect of Italy’s pension problem (and of most industrial countries) is a temporary one, albeit lasting for a protracted period, since dependency ratios are expected to reach a peak in the year 2050 and decline relatively rapidly thereafter. The most desirable strategy to deal with such a temporary demographic bulge would be to spread its cost across a large number of generations. In practice this would entail setting contributions and benefits to secure a modest but decreasing surplus over the next three to four decades to finance part of the transition and leaving the remainder to be financed by subsequent generations.

3. The 1995 reform

a. The new system

The 1995 reform law replaces an income-based system with a contribution-based system that will nonetheless continue to operate on a pay-as-you-go basis. The two main changes introduced by the reform in the area of retirement benefits are: (i) the introduction of a link between benefits and lifetime contributions, and (ii) the abolition of the system of seniority pensions that allowed early retirement without penalties. Under the new system, early retirement will still be possible, but under more stringent conditions and with penalties. The principal elements of the new law are:

• To qualify for retirement, a worker will have to meet one of the following criteria: (i) 57 years of age and at least five years of contributions, or (ii) 40 years of contributions. In both cases, a minimum amount of lifetime contributions is also needed.

• A retiree’s first year pension will be computed by multiplying (i) the value of accrued lifetime contributions capitalized at a rate equal to the 5-year moving average of nominal GDP growth (the pensioner’s “capital”) by (ii) a “transformation coefficient” stipulated in the law, which will depend on the age of retirement. 1/ A peculiarity of the system, however, is that the pensioner’s “capital” is computed using contribution rates that are higher than those actually paid: for dependent workers the system recognizes a rate of contribution of 33 percent, although total contributions (employer and employee) amount to 32 percent; self-employed workers are recognized a contribution rate of 20 percent, but actually pay 15 percent. Pensions will be indexed only to inflation.

• Rules governing invalidity and survivors’ pensions have been tightened. Benefits will now be linked to the level of income of the invalid and/or survivor. As a result, recipients of these pensions may see their benefits reduced by up to 50 percent. 2/

In addition, the law contains various other measures aimed at correcting existing distortions and closing tax loopholes, effectively broadening the base of contributions. These include:

• Some categories of self-employed workers exempt from social security contributions until recently will now be required to make contributions on the basis of their work-related income. 3/

• Contributions of civil servants, until now calculated only on a fraction of their income, will now be based on their total remuneration.

• An income-based contribution to a fund for public housing (contributo GESCAL) scheduled to expire at end-1995 has been made permanent and the proceeds have been earmarked to finance pensions.

The reform also relabels as pension contributions part of the contributions to other welfare funds. Thus, although the overall contribution rate will remain unchanged, the contributions earmarked to finance pension funds will increase from 27 to 32 percent. In addition, the law stipulates that if the estimated savings through 1998 do not materialize, key parameters of the system could be revised.

b. Transitional arrangements

The new system will be immediately in force for all individuals who begin to work on or after January 1, 1996, but will not at all affect workers with more than 18 years of contributions as at December 31, 1995. 1/ Workers with at least one year but no more than 18 years of contributions as at December 31, 1995 will have their pensions computed as a weighted average of the benefits generated by the old and new formulae, with weights given by the number of years of contribution before and after 1995 respectively. They will also, however, have the option of shifting entirely to the new system. As a result, new retirees will have their pensions computed partially on the basis of the new system only beginning in 2013; only from 2036 onwards will all new pensions be calculated entirely on the basis of the new system; and pensions computed under the new rules will not reach an important share of total pensions before the second half of the next century.

For those not affected by the new system, early retirement with a full pension will still be feasible, although under conditions that will become increasingly stringent over the next decade; these conditions will be tightened faster for self-employed than for dependent workers (Table 2). In addition, civil servants will be eligible for early retirement with less than a full pension if they meet softer eligibility criteria in terms of minimum age or a minimum number of years of contribution; these criteria will also be tightened gradually.

The penalties range from 1 percent for those retiring with 34 years of contribution to 35 percent for those retiring with 20 years of contribution.

The pension is reduced proportionately to the number of years needed to reach 35 years of contribution.

4. The new system in the long run

This section examines the long-run properties of the new system and compares them with those of the Amato system. 2/ Under the Amato system, pensions were computed as a fixed percentage (2 percent) of lifetime average earnings, adjusted by the number of years of contribution. Real past earnings were revalued at the rate of 1 percent annually. Thus, the pension of an individual retiring in year T with n years of contributions (at least 35) would have been given by:


As explained earlier, under the new system pensions are given by the product of a transformation coefficient β which depends on age at retirement (e), and the accrued value of lifetime contributions:


where τ is the contribution rate stipulated for the computations and γ is an accrual fator. 1/ Both formulas can be re-written as the product of two factors: (i) a coefficient denoting the yield per year of contribution; and (ii) a measure of the accrued value of lifetime earnings, computed using arbitrary accrual rates:


In the new system, the first factor, or “yield” coefficient, is the product of the contribution rate and the transformation coefficients stipulated by the law; under the Amato regime the yield coefficient was 2 percent irrespective of age. As for the second term, the main difference is that while under the Amato regime the accrual rate was 1 percent, under the new system it is a moving average of rates of growth of GDP.

a. Generosity

A comparison of equations (3) and (4) reveals that, given an individual’s history of lifetime earnings, the two systems could generate different levels of pensions as a result of two factors: different yield coefficients and different accrual rates. The table below compares the yields per year of contribution implied by the Amato and Dini systems, taking into account differences in age and contribution rates.

article image

Clearly, from the point of view of the yield coefficients, the Dini system is less generous than the Amato system for all dependent workers retiring before the age of 65. Moreover, whereas under the Amato system a self-employed and a dependent worker with the same lifetime income profile would have received identical pensions, under the Dini system the pension of the self-employed would be 40 percent lower, reflecting the fact that contribution rates of the self-employed are less than half of those of dependent workers. Thus, the Dini system introduces an important change in the structure of pension benefits in Italy.

While the yield coefficients are in general lower under the Dini system, GDP growth rates above 1 percent would tend to render the Dini system more generous than the Amato system. The net result of combining these effects under the assumption of real GDP and earnings growth rates of 1.5 percent (the scenario underlying the parameters stipulated by law) is shown in Chart 3. The Chart plots the ratio of Dini to Amato pensions, for different combinations of age and seniority at retirement.

Chart 3

ITALY Ratio of Dini to Amato Pensions

Citation: IMF Staff Country Reports 1996, 035; 10.5089/9781451819694.002.A004

For dependent workers, the new system generates higher pensions (ratios higher than one) only for individuals retiring at 63 with at least 39 years of contributions, or for individuals retiring at higher ages. On average, individuals retiring at age 65 would get a pension about 6 percent higher than under the Amato system. At the other end, individuals retiring at age 57 would get a pension about 15 percent lower under the Dini system. For self-employed workers, who account for about 10 percent of the pensions paid by the social security institute (INPS), pensions are one-half to one-third lower than under the Amato system, depending on retirement age. The reduction in benefits of the self-employed represents a substantial cutback but not a complete elimination of the implicit subsidy provided under the Amato system.

The estimated savings generated by the reform in the case illustrated in Chart 3 (i.e., based on the assumption of GDP and earnings growth of 1.5 percent) is of the order of 9 percent of the level of pension outlays under the Amato system. 1/ If growth of 1 percent were assumed, the Dini system would generate lower pensions in almost all cases (with the exception of dependent workers retiring at age 65). If GDP growth of 2 percent is assumed, benefits under the Dini system become relatively more generous for dependent individuals retiring at ages 61 or above. Still, the estimated savings for all workers (dependent and self-employed) under the assumptions of (i) a uniform distribution of retirees by age and seniority and (ii) 2 percent growth, would be of the order of 3 percent.

Savings are likely to be even larger if the reduction in survivors’ pensions envisaged in the law is taken into account. The new system reduces the average fraction of a deceased retiree’s pension that a surviving spouse and/or children receive, by linking it to the survivor’s income. As shown in Appendix I, the resulting long-run savings could be of the order of 1 percentage point of GDP.

b. Solvency

Whereas faster growth tends to increase the average pension generated by the Dini system relative to the Amato system, this would not compromise the new system’s solvency. In fact, in the Dini system, economic growth above 1.5 percent generates pensions that are less than actuarially fair for the pensioner. Weaker growth generates a lower level of pensions because contributions accrue at a lower rate and, thus, generate a lower pensioner’s capital. However, for a given capital, slower growth renders the coefficient of transformation, the rate at which this “capital” is eroded after retirement, too high. 1/

To illustrate this point, it may be useful to liken the new system to a simple annuity system: for the present value of the stream of pension benefits to equal the pensioner’s capital at the time of retirement, the coefficient of transformation must be a function of the relevant interest rate (in this case the rate of growth of the base of contributions, or earnings) and the number of payments to be made (which depends on the individual’s residual life expectancy at the time of retirement). The coefficients given by the law have been derived on the basis of an “interest rate” of 1.5 percent and the existing information on life expectancy. Thus, if earnings grow more slowly or if retirees live longer than expected, the present value of benefits will exceed the pensioner’s capital.

c. Retirement incentives

Another important change introduced by the new system relates to the incentives to delay retirement. As noted in subsection a. under the Amato system the yield per year of contribution was fixed at 2 percent, independently of age at retirement or seniority. Under the new system, the yield per year of contribution rises with retirement age, reflecting the decline in residual life expectancy arising from postponing retirement. This introduces an incentive to postpone retirement.

Chart 4 illustrates the effect of delaying retirement on the level of the pension under the Dini and Amato systems, for an individual eligible for retirement at the age of 57 under either system. 2/ In order to focus exclusively on the effect of postponing retirement, the pension that the individual would have obtained under each system if retiring at 57 has been normalized to 100. Given the fixed yield coefficient, the positive slope of the curve under the Amato system reflects exclusively the increase in accrued lifetime income as a result of remaining one extra year in the labor force. The Dini system, which adjusts the transformation coefficients for retirement age, provides almost twice as large an incentive to postpone retirement.

Italy Incentives to Postpone Retirement

The higher incentive to postpone retirement provided by the new system would further improve the finances of the social security institute. For example, with steady state population growth of 0.5 percent a year, a one-year increase in the average retirement age from 56 to 57 1/ could reduce the ratio of pensions to GDP by almost 1 percentage point. 2/

d. The contribution-benefit link

As discussed earlier, Italy’s new pensions formula establishes, at least nominally, a one-to-one link between contributions and benefits. The possibility of establishing a close link between contributions and benefits in a pay-as-you-go system has often been questioned, because in such a system there is no assurance that every year the flow of contributions would suffice to pay actuarially fair benefits to all retirees. As a result, there is always the possibility that changes in fiscal policy variables may be necessary. Nevertheless, as Auerbach and Kotlikoff (1987, p. 155) explain, individuals making consumption and labor supply decisions have no reason to take account of the fact that their benefits are being financed by members of the next generation.

In any case, even considering the possibility that the actual amount of benefits may not be identical to the accrued value of lifetime contributions due to changes in the state of the economy or in policy variables, it could be argued that the new regime establishes a substantial marginal link between contributions and benefits. This implies that, to some extent, social security contributions are not perceived as a tax but as defferal of ernings: contributions paid now are in part offset by future benefits. As a result, the distortionary effect of labor income taxation is effectively reduced. 3/ As shown by Auerbach and Kotlikoff (1985), the efficiency gains from such a link can be substantial: using a model calibrated for the U.S. economy, they find that switching from a no-link situation to one characterized by a one-to-one marginal link (although still in a pay-as-you-go system) could lead to efficiency gains equivalent to a permanent increase of 1 percent in the level of GNP. Thus, while there are at present no estimates of the likely efficiency gains from linking benefits to contributions for Italy, estimates for the U.S. would suggest that this issue should not be overlooked.

e. Robustness of the long-run equilibrium

Although the new system links benefits to contributions, aiming at providing actuarially fair pensions, the fact that retirees’ benefits will continue to be paid by younger generations implies that the solvency of the system will depend on the combined behavior of GDP, labor force, and population growth rates. Appendix II shows two key results regarding the finances of the social security institute under the new system:

(1) since the rate of capitalization of contributions equals the rate of growth of GDP in the new system, the cash flow of the social security institute will be zero in steady state only if the share of labor income in GDP remains constant. The logic behind this condition is that, while pension liabilities will grow with GDP, contributions will grow in line with the product of (i) average earnings and (ii) employment. Balanced growth between contributions and outlays thus requires that total labor earnings and GDP grow at the same rate;

(2) even in the case where each individual is getting an actuarially fair pension, it is possible that the cash flow of the social security institute could temporarily be in deficit. This can happen if birth rates fall: growth in the labor force would then decelerate before growth in the elderly population, implying a delayed temporary increase in elderly dependency ratios before the age structure of the population fully adjusts to the new birth rate. The effect of this “demographic transition,” which in practice could take decades, is a direct hit at the finances of the social security system, which would face a slower growth in revenues than in pens ion-related outlays.

Thus, whereas an actuarially fair pay-as-you-go system would exhibit a balanced cash-flow in steady state with a constant population growth rate, it would still run deficits during a demographic transition. Therefore, the Dini system is not explicitly equipped to deal with one of the most pressing issues of Italy’s public finances over the next four or five decades: although the new law allows for adjustments in the transformation coefficients every 10 years in line with prevailing life expectancy, such adjustments would only ensure actuarial fairness.

5. The gradual phasing-in of the new system

While it is appropriate to compare the new system with the Amato system when assessing the long-run effects of the reform, medium-term analyses of the likely evolution of pension outlays from their current levels should be based on the comparisons between the new system and the one prevailing prior to the 1992 reform. This is particularly relevant if these comparisons are to be used to infer whether it would be desirable to accelerate or delay the phasing-in of the new system. Thus, the policies and estimates discussed in this section are based on the premise of a gradual 15-year transition from the system prevailing in 1995 (that is, before the Amato system could be phased in) to the Dini system, as stipulated by the 1995 reform law.

a. Budgetary effects of the reform in the medium term

The 1995 reform law was accompanied by an estimate of its likely budgetary effect over the next 10 years. Table 3 provides a summary of the official estimates. Overall, the reform is expected to yield annual savings of the order of 0.4-0.5 percent of GDP in the period 1995-05, with slightly more than half of those savings stemming from lower expenditures. Most of the reduction in expenditures is explained by the effects of the gradual tightening of eligibility requirements for early retirement, while the savings generated by the revisions to the survival and invalidity systems tend to be offset by the incentives to be provided for the creation of private retirement funds. Savings coming from higher revenues are explained mainly by the contributions of some self-employed workers until now exempted from social security contributions and the extension and relabelling of the contribution for public housing.

Table 3.

Official Estimates of the Savings Generated by the 1995 Pension Reform

(In percent of GDP)

The official estimates of savings should be interpreted with caution, as the underlying assumptions are not uncontroversial. In a recent study of the likely effects of the reform, Peracchi and Rossi (1995) argue that the official estimates overstate the savings derived from the tighter conditions for early retirement, because they are based on an overly-optimistic assumption regarding the contraction in the flow of workers opting for early retirement that would be induced by the reform.

Another area where the official estimates may be unreliable is the revenue to be obtained from professionals previously exempted (which account for about one quarter of the total savings), which, as noted, has run into legal difficulties and where enforcing compliance will be difficult. Moreover, it should be kept in mind that these payments only provide temporary cash-flow relief since, by contributing, these professionals are also accruing rights to future pensions.

b. Accelerating the phasing-in

The 1995 reform has been criticized for prescribing an extremely slow phasing-in of the new system, a defect it shares with the Amato reform. However, an acceleration of the phasing-in may not generate substantial additional savings for two reasons. First, if the new formula were used retroactively for all retirees beginning immediately, this would entail capitalizing their contributions at the GDP growth rates of the past 35-40 years or so, which have been rather high on average; 1/ this would generate relatively high pensions. Second, while the eligibility criteria for early retirement with a full pension are to be tightened gradually over a decade for dependent workers, they are to be tightened over a 2-year period for the self-employed (where projected savings are sizeable), leaving little room for further improvements.

Table 4 shows the likely yield of selected measures aimed at accelerating the phasing in of the new system:

• dropping the grandfather rule applied to those with at least 18 years of contributions as at December 31, 1995, and computing their retirement benefits in a pro-rated manner, just as in the case of workers with 1-18 years of contribution at end-1995. The savings generated by this measure would be minimal, in part due to the effect of high growth rates in the 1960s noted above, and in part due to the low relative weight that the new formula would have on the pensions of those retiring over the next decade;

• increasing the contribution rate of the self-employed with at least 18 years of contributions to 32 percent. The rationale for this measure is that since these individuals will eventually receive the same benefits as dependent workers, they should pay the same contribution rate over their remaining years of employment. The measure would initially yield savings of the order of ½ percent of GDP, but these would decline to about 0.2 percent by 2005 as the number of contributors from this pool decreases over time;

• immediately increasing the minimum age (57) and seniority (40 years of contribution) required for early retirement without a penalty. Except for the first two years, this measure would generate savings of 0.1 to 0.2 percent of GDP. A softer version, accelerating the envisaged increase in the minimum age to 57 by the year 2001 while leaving the minimum seniority requirement unchanged, would generate minimal savings. On the other hand, accelerating the envisaged increase in the minimum seniority requirement to 40 years of contribution by the year 2001, while leaving the minimum age requirement unchanged, would generate small savings, albeit larger than those generated by the faster increase in the minimum age;

• accelerating the increase in both minimum age and seniority by the year 2000 would generate savings of the order of 0.1 percent of GDP or less.

Thus, none of these measures, except for an increase in the contribution rate of the self-employed (a politically difficult move), generates substantial savings. Other measures involving increases in contribution rates could generate immediate savings but are not economically attractive for two reasons: (i) higher contributions by those affected by the reform would eventually imply higher pensions; and (ii) contribution rates are already high. Thus, it would appear that the most effective way of generating savings in the near future would entail an across-the-board reduction of benefits for all age groups, presented either as a modification to the new system and an immediate implementation of it; or a reduction in benefits for those affected by the reform (say, through lower transformation coefficients) and equivalent taxation of the benefits of those whose pensions will be calculated according to the old formula.

c. The demographic transition

As mentioned earlier, the new system will continue to operate on a pay-as-you-go basis and, therefore, will be vulnerable to a deterioration in dependency ratios. Antichi (1995) projects that the system’s equilibrium contribution rate for dependent workers will increase rapidly in the first part of the next century, from about 32 percent (the statutory contribution rate) to a peak of near 40 percent around 2035. 1/ This increase is driven almost entirely by adverse demographics, as the increase in the ratio of pensioners to contributors more than offsets the gradual decrease in the average pension. 2/

Antichi also shows that, despite its inability to absorb the effects of the demographic transition, the new system would still generate some savings in relation to the expenditures that the Amato system would have implied. These savings are proxied by the difference between the equilibrium rates generated in the old and new systems. He finds that beyond 2015, when most of the medium-term savings described in the previous sub-section will have disappeared (and the equilibrium contribution rate risen to above the statutory 32 percent), the new system generates relatively lower equilibrium contribution rates only if the transformation coefficients are adjusted as life expectancy increases. 1/ In this case, the gains can be considerable in the long run, with the equilibrium rate under the new system about 5 percentage points below that generated by the Amato system.

6. Conclusions

The reform has put in place a system with better steady-state economic properties than the Amato system: actuarial soundness, a modest incentive to postpone retirement, a closer link between contributions and benefits, and a less heterogeneous treatment of different categories of workers. Also, the law has redefined the system in terms of a clear set of parameters that could be adjusted without requiring a new reform.

The new system is likely to produce a lower ratio of pensions to GDP in the long run relative to the one that would have resulted from the system introduced by the 1992 reform. Savings will come from various fronts: a moderate reduction in benefits of dependent workers, a substantial reduction in benefits of self-employed workers, a reduction in survivors’ benefits, and a reduction in the ratio of pensioners to contributors as a result of increased incentives to postpone retirement. In addition, the new system, by linking contributions to benefits, is likely to produce efficiency gains stemming from a dampening of the distortionary effects of labor income taxation. These gains have been found to be substantial in a study for the U.S. economy and, because of its higher marginal income tax rates, could be even higher in Italy.

On the other hand, the new system leaves in place high contribution rates and remains vulnerable to demographic changes. The provision allowing for 10-year adjustments of the transformation coefficients for changes in life expectancy is an important feature, necessary to limit to the growth of pensions to what is sustainable from a steady-state point of view; but these adjustments will not prevent a deterioration of the finances of the social security institute in the face of a demographic transition. In addition, the law does not provide for an automatic adjustment of the parameters, but instead calls upon the social partners to meet every 10 years to negotiate the necessary adjustments.

Fully addressing the problems of high rates and the approaching demographic transition would require an across-the-board reduction in the level of benefits and contributions. Moreover, it may be necessary to adjust the system promptly so that an important part of the negative effect of the surge in retirements expected by the year 2040-50 is borne by current generations. This will require running moderate surpluses over the next four to five decades. Two measures that could be implemented in order to achieve this objective are: (i) a reduction in the transformation coefficients and a steepening of their age profile; this would generate savings that would exceed the proportional reduction in the average coefficients, as the steeper profile would induce delayed retirement; and (ii) computing the present value of lifetime contributions on the basis of the contribution rates actually paid and not the notional rates.

APPENDIX I Pension Benefits In the old and New systems

This Appendix provides a detailed comparison of retirement and survivor benefits under the new and old systems.

Retirement pensions

Under the Amato regime, pension benefits of an individual retiring in year T with n years of contributions (n ≥ 35) would have been given by:


where w represents the average pensionable income, defined as the average wage over the contribution period, with real wages revalued by at an annual rate of 1 percent:


Under the new system, pensions are given by:


where βe is a coefficient that depends on the age of retirement, and M is the present value, as at the time of retirement, of lifetime contributions:


γ is a cumulative accrual factor given by:


and μt is the a 5-year moving average (ending in t) of the annual rates of growth of real GOP.

After substituting (2) in (1), and (4) and (5) in (3), the ratio of new to old pensions can be written as:

PDPA =[βeτ][Σt=TnT1wtγt][0.02][Σt=TnT1wt(1.01)Tt](6)

Survivors’ benefits

Survivors’ benefits can be thought of as a premium received by the pensioner over his retirement years. Consider the case of an individual that retires at t=T with a pension P, lives until year T*, and is survived by a spouse who receives a fraction δ of his pension until year T**. The present value (PV) of the retirement and survivors’ pensions is:


The value of a (higher) pension P’ received only during retirement (i.e. not transferable), that would generate the same PV of benefits as (7) would be given by:


Equation (8) shows that survivor’s benefits are equivalent to a premium over the retirement pension that depends positively on the fraction 6 and the number of years that the spouse survives the pensioner (T**-T*) and inversely on the retiree’s residual life expectancy at retirement (T*-T).

The table below shows the savings that can be derived from reductions in the coefficient δ from its pre-reform value of 0.6 to 0.50, 0.40, and 0.30. As explained in the text, the reform law has linked the value of δ to the survivor’s overall level of income, effectively creating four categories with values of δ ranging from 0.3 to 0.6. Since in Italy female residual life expectancy is about 5 years longer than that of the male at the age of 60, the table shows the results for three different scenarios: (i) same ages for husband and wife, (ii) wife three years younger, and (iii) wife 5 years younger.

The table shows that the tightening of the conditions for survivor’s benefits stipulated in the reform law may lead to an appreciable reduction in pension outlays: a 6 percent reduction in the average pension could reduce the ratio of pensions to GDP from 15 to 14 percent, assuming that all other variables remain constant.

APPENDIX II Economic Consequences of Linking Contributions and Benefits

In this Appendix, a simple analytical model is used to illustrate the effects of the introduction of a link between contribution and benefits.

A simple overlapping generations model

The model assumes no population growth; thus in every period there is only a single young and a single old individual. Lifetime preferences are assumed to be given by:


where U is a well-behaved utility function, and cy and co represent consumption in the first and second years of life respectively. The individual is endowed with L units of time in each period but works only in the first period. Thus, the utility function (1) includes only leisure in the first period of life. During his first year the individual pays an income tax (τ) and, in the second year, he gets a pension with a present value of P. Therefore, the lifetime budget constraint faced by this individual is:


No contribution-benefits link

If the individual perceives no link between contributions and benefits, he will maximize (1) subject to (2) taking P as a lump-sum transfer. The first order conditions for the solution of the problem would be:


Equation (3) illustrates the source of the welfare cost of wage-based contributions: a wedge introduced on the relative prices of consumption and leisure. Equation (4) is the standard Euler equation for consumption. The final demand functions would be given by:


Thus, at the margin, a higher wage tax leads to substitution away from consumption toward leisure. Even if the higher tax leads eventually to a higher pension--but the individual fails to see the connection-- the individual would be worse-off.

Linking contributions to benefits

Italy’s new pensions formula establishes a close link between contributions and benefits. However, since in a pay-as-you-go system there is no assurance that every year the flow of contributions would suffice to pay actuarially fair benefits to all retirees, there is always the possibility that changes in other fiscal variables may be necessary. Thus a realistic way of characterizing the perceived link between contributions and benefits established by the new regime could be:


where, as before, P represents the present value of pension benefits received in the second period. Equation (8) shows that the pension can be thought of as the sum of two components: (i) a lump-sum payment, and (ii) an amount proportional to contributions, with θ representing the marginal link. The first order conditions for an individual maximizing his utility function (1) subject to the budget constraint given by (2) but perceiving a link between contributions and benefits as given by (8) are:


A stronger marginal contribution-benefits link (a higher θ) dampens the negative effect of the wage tax on the individual’s optimal decisions. In the case where θ=1, the individual would face the same first order conditions that would prevail under a funded social security system. This, however, is an efficiency issue, as the general equilibrium properties of a system characterized by θ=1 would likely be different from those prevailing under a funded system. In particular, capital formation would be higher in the funded system, where the pensions system entails actual saving by workers, whereas in the pay-as-you-go system with θ=1 pensions would entail intergenerational transfers.

APPENDIX III Robustness of the Long-Run Equilibrium

This Appendix illustrates the effects of a demographic transition on the cash flow of an actuarially-fair pay-as-you-go system. The discussion is based on a simple overlapping generations model With 2-period-lived individuals.

Demographic dynamics

The total population (N) is comprised of two groups: the young generation currently employed (L) and the elderly, all of whom are retired (R). Denoting the (gross) rate of growth of the labor force by λ, this 2-period model implies the following identities:


The first identity simply relates current and last-period labor forces through the rate of growth λ; the second identity shows that the dynamics of the elderly population react to changes in λ with a lag; and the third identity shows that total population growth would equal λ only if the latter were constant. An acceleration in λ leads initially to a less-than-proportional increase in the rate of population growth,.

Taxpayers, retirees and the public finances

In any given period, each young individual pays social security contributions at a rate τ of his wage (w), and each retired person obtains a pension equivalent to the product of a transformation coefficient (β) and a pensionable capital (M). This capital is the value of the pensioner’s earlier contributions capitalized at the (gross) rate γ. Thus, in period t, the cash flow of the social security institute is:


where Mt equals γτwt-1. Assuming that real wages grow at the (gross) rate θ, the cash flow of the social security authority (SS) can be written as:


Therefore, with β and γ given by law, the existence of a deficit or surplus in the finances of the SS depends on the rate of growth of the labor force and the rate of growth of earnings: starting from a balanced position, a reduction in either of those two variables would generate a deficit.

Actuarially fair pensions

In order to provide an actuarially fair pension, β must be chosen in a way that ensures that the present value of the pension received during retirement equals the contribution made by the individual during his working time (first period in this model):


Clearly, if the rate at which contributions capitalize according to the law (γ) equals the real interest rate (ρ), then β*=1. The cash flow implications of selecting an actuarially fair β can be obtained by combining equations (5) and (6):


This is simply the condition for the yield of a pay-as-you-go system to dominate that of a funded system as demonstrated by Samuelson (1958) and Aaron (1966). As described above, it implies that if the government were to pay actuarially fair pensions to all individuals, it would run a permanent surplus whenever the product of the rate of growth of the labor force times the rate of growth of earnings exceeds the real interest rate.

In the Italian case, the steady-state rate of capitalization of contributions is equal to the rate of growth of GDP (Ψ). Equation (7) suggests that in the simple case in which Ψ equals ρ, a balanced cash flow require:


that is, a constant share of labor income in value added. If either earnings growth or labor force growth were to decelerate (i.e., if the share of labor income in value added were to fall) the social security system would run a deficit, even though each individual is set to receive an actuarially fair pension.

Numerous studies have made this case; see, for example, Canziani and Demekas (1995) and Van den Noord (1993).


See also chapter 3 of OECD (1988).


The December 1992 reform increased the minimum retirement age for old-age pensions, lengthened the reference period for calculating pensionable earnings, increased the minimum number of years of contributions required for seniority pensions, replaced wage indexation of pensions by price indexation, and began a gradual elimination of special rules for public sector employees.


The coefficients increase from 4.7 percent at age 57 to 6.1 percent at age 65; the increasing profile of these coefficients is intended to adjust for residual life expectancy. The law also stipulates that these coefficients will be adjusted every ten years in line with prevailing life expectancy. Appendix I contains a detailed description of the formulae used by the present and previous systems.


In particular, survivors’ benefits have been reduced by rates of 25, 40 and 50 percent, depending on the survivor’s overall level of income.


This group, known as lavoro para-subordinate, includes free-lancers and other semi-autonomous workers. This measure has been recently challenged in court, and compliance may be difficult to enforce.


This group was also grandfathered by the 1992 Amato reform and will have its pensions computed on the basis of their income during the last 10 years of contribution.


Although the Amato system was never fully in place, it would have been phased in over the same period as the Dini system. Thus, for the purpose of long-run comparisons, the Amato system constitutes the relevant benchmark.


See Appendix I for the detailed derivations.


This is under the conservative assumption of a uniform distribution of retirees by age and seniority.


An increase in life expectancy would have the same effect.


The simulations are based on the case of an individual reaching the age of 57 with 35 years of contributions. Real GDP and earnings growth of 1.5 percent underlie the calculations.


The average age of male pensioners (old age and seniority pensions) active as of December 1991 was 57.5. At the same time, more than 80 percent of women receiving an old-age pension had retired at 55.


This assumes unchanged labor participation and unemployment rates, and takes account of the fact that pensions are currently about 15 percent of GDP.


This point is illustrated in detail in Appendix II.


GDP growth averaged 5.8 percent in the 1960s, 3.8 percent in the 1970s, 2.2 percent in the 1980s, and 1.3 percent in 1990-95.


The peak level of the equilibrium contribution rate depends (inversely) on the assumed long-run rate of GDP growth.


This result is independent of whether or not the transformation coefficients are adjusted every 10 years for changes in life expectancy.


The different assessments of the new system put forth by the Ministry of the Treasury and the Bank of Italy are mostly due to their assumptions regarding the adjustment to the transformation coefficients: the Bank of Italy assumes no adjustments while the Ministry assumes 10-year adjustments in line with changes in life expectancy.


The estimates in the table assume that the male worker retires at 60 with residual life expecttancy of 18 and that the wife’ life expectancy is 83.
