I. Generational Accounting for France1

A. Introduction

1. This paper presents a set of generational accounts to contribute to the assessment of France’s long-term fiscal position. Understanding the sustainability of fiscal policy in France from a generational perspective is important in many respects. France has one of the most extensive social security and welfare system among the large industrialized countries; public expenditure on health as a share of GDP is the highest in Europe; and compared to other OECD countries, its pension outlays are also relatively large (Table I-1). Not only are benefits high, but so is the level of taxation: taxes needed to finance social security funds have risen from less than 15 percent of wage income in 1950 to almost 50 percent in 1996. In recent years, there have been mounting concerns regarding the continuing viability of such an extensive social security system in general, and its unfunded pay-as-you-go pension schemes and universal health care in particular. Slower rates of economic growth and the prospective aging of the population have led to further concerns that the implied tax burden on younger (working) generations in the future will be too high, assuming the continuation of the general thrust of current policy settings. Projected trends of changes in the age structure reveal that an increasing number of retirees must be supported by a declining number of workers, with the old-age dependency ratio likely to rise from 0.35 in 1995 to 0.60 by 2030 (Tables I-2 and I-3).

2. Behind concerns about the sustainability of the welfare system and the current real level of public consumption expenditures looms the fundamental question of how fiscal policy affects the distribution of income between generations. In general, fiscal settings which imply markedly increased burdens on some generations relative to other generations, constitute a cause for concern. As pointed out by Kotlikoff (1992), the standard measure of the budget deficit cannot appropriately address this question. In contrast, generational accounting provides a tool for the investigation of the intergenerational distributional effects of fiscal policy. The purpose of this paper is thus to use this technique to determine whether current fiscal policies in France can be sustained without requiring future generations to pay higher net taxes over their lifetimes than current generations pay.

3. Our calculations indicate that France’s generational policy is imbalanced against future generations. In spite of the substantial fiscal consolidation projected to take place in the next five years in order to align the fiscal stance in France with the pattern envisaged by the “Stability and Growth Pact,” social benefits (in particular pensions) imply a projected net tax burden on future French citizens, adjusted for income growth that is about one and a half times as large as that facing current young generations. While the precise size of this generational imbalance depends on a number of assumptions, including rates of discount and productivity growth, the direction of the imbalance is unmistakable, as it holds under alternative assumptions about these parameters. These projections do not build in feedback effects from policies that may be necessary to ensure the “balancing” in the future of the government’s intertemporal budget constraint, such as increases in taxation, which could significantly weaken the underlying growth of income, thereby amplifying the imbalance. Compared with the situation in other countries for which generational accounts have been computed (OECD, 1995), the size of the generational imbalance reported here for France is larger than that of Germany and Sweden, while smaller than that reported for Italy—before the 1995 reform—and the United States.

4. This paper departs from the standard presentation of generational accounting—which is based only on remaining future net tax payments—in that it provides also an indication of the size of generational imbalance existing between currently living generations (old versus younger ones) taking into account the net tax paid by current adults in the past. On this basis, the calculations show that protecting the “Babyboom” generations from any change in fiscal policy (thus leaving to young and future generations the full responsibility to redress any fiscal imbalance) would imply a projected net tax burden on those now aged less than 25 that is quite more than one and a half times as large as that facing those born around 1950.

5. The paper is organized as follows. The generational accounting framework is outlined, followed by a discussion of its major limitations in Section B. The specific case of France, including the construction of the accounts, a discussion of key parameters used, and the main findings is presented in Section C. The next section (Section D) places France’s generational policy in an international perspective. In Section E, the lifetime net tax payments of current adults are calculated and compared with those of younger living generations. Alternative scenarios on policies aimed at redressing the generational imbalance are discussed in Section F. The final section summarizes these findings and concludes. Appendices provide details on the calculation of the accounts, including the data used, and sensitivity analysis with respect to key parameters.

B. The Generational Accounting Framework

6. Government deficits, taxes, transfer payments, and other expenditures affect the distribution of income and wealth among members of both the same generation and different generations. Conventional deficit accounting provides little information regarding either distribution. Take for example the case of a change in an unfunded pay-as-you-go social security system which lowers the net taxes of the old while increasing those of the young by an equal amount, but avoids the need for government borrowing at any date. Despite the complete absence of any change in government deficit, the introduction of this social security scheme has generational effects, in that the generational account of the current old falls, while that of every younger generation rises. Standard generational accounts provide estimates of the remaining lifetime net taxes of persons born at different times under certain economic and demographic assumptions. Therefore, they not only provide a new perspective for the study of the distributional effects of fiscal policy, which has traditionally been focused on intragenerational aspects,2 but they can be a useful tool in assessing the sustainability of government accounts. In recent years, generational accounts have been computed for more than a dozen countries, including Germany, Italy, Norway, Sweden, and the United States.

The methodology

7. Generational accounting is a new technique developed by Auerbach, Gokhale, and Kotlikoff (1991), and Kotlikoff (1992) that can be used to study the effects on different generations of the government’s fiscal policy. In this framework, the explicit analysis of the impact of fiscal policy on the welfare of different generations starts out by computing generational accounts, which simply show the present value of the expected net tax payments of a representative individual of a given generation, where “net taxes” refers to taxes paid less transfers received and a “generation” is defined as a cohort of individuals of the same age and sex.

8. Generational accounts are based on the premise that all government purchases must be paid for, i.e., for a given path of government spending, a reduction in one generation’s account can only be achieved through expanding other generations’ accounts in a way that respects the government’s intertemporal budget constraint. The budget constraint implies that the government’s current net wealth plus all future taxes paid to the government minus all transfers paid by the government (future net taxes) must cover all future government spending on goods and services. In order to compare the intergenerational burden, the sum of future net taxes is split into an amount paid by all existing generations from the base year onwards to the end of their lives, and the remaining amount which has to be paid by all future generations during their lives. Hence, more formally, the government’s intertemporal budget constraint can be written as:


9. The first term on the left hand side of this equation adds together the present value of the net payments of existing generations. The expression Nt, k {k=t, t-D} stands for the present value of net remaining lifetime payments to the government of the generation born in year k discounted to year t. The index of this summation runs from age 0 to age D, the maximum length of life. Hence, the first element of this summation (s=0) is Nt, t, which is the present value of net payments of the generation born in year t; the last term (s=D) is Nt,t-D, the present value of remaining net payments of the oldest generation alive in year t, namely those born in year t-D. The second term on the left hand side of the equation adds together the present value of remaining net payments of future generations. The third term on the left hand side Wt denotes the government’s net wealth in year t. The right hand side expresses the present value of government consumption. In the latter expression, G8 stands for government consumption expenditure in year s. All future flows are discounted to year t at the pretax rate of return rj.

10. The term Ntk is defined more explicitly as follows:


In this expression Ts, k stands for the projected average net payment to the government made in year s by a member of the generation born in year k. The term Ps, k stands for the number of surviving members of the cohort in year s who were born in year k. For generations who are born in year k, where k>t, the summation begins in year k.

11. Generational accounts are defined simply as a set of values of Nt, k, one for each existing and future generation, with the property that the combined total value adds up to the right hand side of the intertemporal equation. This formulation makes clear the implications of the government budget constraint; holding the right hand side of the equation fixed, increased (decreased) government payments to (receipts from) existing generations mean a decrease in the first term on the left hand side of the equation and requires an offsetting increase in the second term on the left hand side; i.e., this requires reduced payments to, or increased payments from, future generations.

12. This framework can be used easily to make two types of comparison. First, through the use of lifetime net tax rates, it can be used to compare the lifetime net taxes of future generations, of the generation of people just born, and of different generations born in the past, i.e., it can be used to determine how much future generations are likely to pay in net taxes as compared to generations alive today. Second, generational accounting can be used to compare the effects of actual or proposed policy changes on the remaining lifetime net tax payments of generations currently alive and on future generations.

Limitations of generational accounting

13. Advocates of generational accounting argue that conventional fiscal deficits are essentially meaningless, as gauges either of macroeconomic policy or of intergenerational fairness of government policy, and should be replaced by generational accounts.3 Although these claims have some merits, they have met with a number of criticisms recently (Muellbauer (1992), Haveman (1994), and Buiter (1996)). On the one hand, given the importance of old-age entitlement programs in the industrial world, it is certainly true that conventional deficit measures miss a major part of the action in fiscal policy in the long run, by just providing a snapshot of the present situation without clarifying future trends. On the other hand, there are some practical obstacles to making a wholesale switch to a newer, untested measure of fiscal policy. As with most tools of policy analysis, generational accounting offers a useful perspective, but serves as an imperfect indicator. The accounts often suggest a rough magnitude and general pattern of results, which may be ambiguous and subject to uncertainty as regards future demographic changes and future growth. Apart from the heavy data requirement, the implementation of generational accounting requires specific assumptions on a number of difficult conceptual and theoretical issues, which often raise questions about their ultimate usefulness. Indeed, generational accounts as usually constructed suffer from a number of limitations.

14. First, generational accounts say nothing about the intergenerational distribution of public consumption. They do not impute to any particular generation the value of the government purchases of goods and services. Therefore, they do not show the full net burden that any generation receives from government fiscal policy as a whole. This reflects mostly difficulties in empirical implementation. There is no clear method of allocating the benefits of government purchases such as defense, highways, research, across generations. The reason is that most government purchases are made to provide public services that are used collectively rather than individually.

15. Second, generational accounts do not allow for the general equilibrium repercussions of alternative budgetary policies. In addition, generational accounts ignore all changes in before-tax income and relative prices caused by alternative budget programs. As demonstrated by Buiter (1996), these general equilibrium responses of pre-tax, pre-transfer, and pre-subsidy factor incomes and rate of return may reverse, counteract, or reinforce the impact of budgetary policy changes. For example, policies that decrease the net tax payment by existing generations and increase the net tax payment by future generations are likely to stimulate more current consumption and thereby reduce the saving available to finance investment. This, in turn, will lower productivity and real wage growth and raise real interest rates, which on balance can harm future generations.4

16. Third, generational accounts do not incorporate intergenerational transfers taking place outside the public sector: altruism and bequest motives may raise the possibility of private intergenerational transfers offsetting government transfers. Indeed, the usefulness of generational accounts is closely tied to the strict life-cycle model of household consumption (Buiter, 1996). In addition, for generational accounting to provide useful additional information (relative to standard budget accounting), consumers are required to be forward-looking with perfect foresight, and not subject to liquidity constraints.

17. Fourth, the computation of generational accounts is highly sensitive to assumptions on the future growth of productivity and population, which are subject to considerable uncertainty. Moreover, the choice of discount rate needed to carry out net present value calculations is also difficult: while the absence of liquidity constraint implies that all generations are supposed to have a similar cost of waiting regardless of their age, the riskless setting in which generational accounts are computed implies that the correct discount rate cannot be easily derived from observed long-term interest rates.5

18. Finally, generational accounts as usually presented include only future net tax payments and exclude past net payments. Therefore, they cannot be used to address the politically relevant question of how current younger generations fare compared to their elders based on relative lifetime net tax burdens under current policies.

19. Some of these problems can be minimized, and the use of sensitivity analysis provides some help in forming judgments. For instance, increasing the share of government expenditure that is assigned to individual cohorts will reduce the arbitrariness of the distribution of the fiscal burden, because a smaller part of total taxes becomes diverted toward undifferentiated “government consumption.” Estimation of private intergenerational transfers can also shed some light on the generational stance of fiscal policy, and retrospective calculations can widen the scope of the policy implications (see Kotlikoff, 1994). In this paper these problems are in part dealt with by a careful assignment of government expenditures based on well established concepts of national accounts, as well as by the computation of retrospective generational accounts that permit to compare the lifetime net tax burden of some adult cohorts with that of younger and future generations.

C. The Construction of Generational Accounts for France

Generational profiles and benchmarking aggregates

20. The construction of generational accounts necessitates first projecting each currently living generation’s average taxes less transfers for each future year during which at least some members of the generation will be alive, and then converting these projected net tax payments by individuals into an aggregate present value. This requires projections of population by age and sex, as well as a discount rate to convert flows of net taxes into present values. In the case of France, projections of average future taxes and transfers by age and sex start with the 1995 aggregate taxes and transfers, as well as medium-term projections of transfers and taxes for all levels of government. These aggregate taxes and transfers are distributed across the population by age and sex in each year according to the age and sex pattern observed in 1990 from official survey data. The primary sources for these distributions are the “1990 enquête sur les revenus fiscaux des ménages” the “1991-92 enquête sur les actifs financiers” and the “1990 enquête sur les budgets des families” A detailed account of the construction of these profiles can be found in Appendix I.

21. The resulting age and sex profiles (i.e., the relative tax weight of different living cohorts) are assumed constant through time, except for adjustments reflecting projected changes in the participation rate of women.6 The actual value of individuals’ taxes and payments in the medium term are found by scaling individuals’ payments to achieve aggregate values consistent with taxes in 1995 and the medium-term fiscal projections, which assume inter alia that the economy returns to its “potential” level by the year 2002. For years beyond 2002, it is assumed that all taxes and transfers increase at the same rate as productivity growth.7 Five categories of taxes are distinguished: income tax, property tax, value-added tax, social security contributions, and taxes based on individual wealth (including corporate income taxes, the incidence of which was shifted to asset holders). Transfer payments are categorized into pensions, health, education, and unemployment benefits. For each of these items, the aggregate amounts are allocated according to the existing profiles; all other categories of transfers were included in government consumption. Charts I-1 and I-2 present the distribution of taxes and benefits in the base year 1995.

22. The next step in the construction of France’s generational accounts involves an estimation of the initial stock of government net wealth and projections of future government consumption. Government consumption is determined by a projection over the medium term (see Appendix I), then by a rule that assumes that spending grows over time from its 2002 level to keep pace with population and productivity growth.8 This amounts to assuming that per capita consumption rises at the productivity growth rate. Our estimate of spending includes both government spending on goods and services (excluding health and education spending) as well as public investment, netted by those taxes and receipts not included in the five categories described above. For government net wealth, estimates computed by INSEE (1993) are used. In 1995, the consolidated net wealth of the general government is estimated to be F 800 billion (about 10 percent of GDP), reflecting the 1993 estimate, adjusted for the growth in government debt and the sale of government assets through privatization in the intervening period. The net financial wealth, which is used for the baseline calculation was negative, with net liabilities amounting to F 2,800 billion, obtained by netting off from the general government debt (estimated at F 4,059 billion in 1995), the financial assets of the general government.

23. Using the government intertemporal budget constraint given above, the average present value lifetime net tax payment of each member of each future generation was then determined as a residual under the assumption that the average lifetime tax payment of successive generations rises at the economy’s rate of productivity growth.

24. The procedure followed in this study was aimed at minimizing the arbitrariness in the labeling of taxes and transfers, by making sure that all flows are fully taken into account on a national accounts basis, e.g., by recovering the government deficit figure after all flows are considered (Table I-4). The age and gender distribution of the net tax burden was allocated as large a fraction as possible to individual cohorts, so as to minimize the problem that the generational accounts do not recognize the intergenerational distributional implications of the government consumption program (see Buiter (1995), and Section B above).

Key assumptions and other technical aspects

25. A key ingredient in the calculation of generational accounts is the economic and demographic assumptions needed in order to extend and discount the components of the zero-sum equation. They are the rate of productivity growth, the discount rate, and the rate of population growth. For present purposes, the average annual growth of productivity is assumed to be constant at 1.0 percent per year over the long run (baseline case). A discount rate of 3 percent is assumed; this is midway between the average yield on government bonds and the real rate of return to private sector capital, and thus provides a reasonable indicator of society’s trade-off between present and future consumption. Alternative values of 4 percent and 5 percent are also used to gauge the sensitivity of the results to this particular parameter. The projection of population by age and sex for 1995-2050 provided by INSEE corresponds to the high growth case (i.e., a fertility rate of 2.1 percent and no immigration) found in Dinh (1995). This trend is extrapolated through 2200 by assuming that the birth rate stabilizes after 2050.

26. Other technical assumptions made in this paper concern participation rates, the growth rate of medical expenditure, and pension indexation. As regards the rate of participation, a number of studies point to past and projected increases in the participation of women in the labor force.9 This trend is captured in the implementation presented here by incorporating the observation that this increase has taken place through two mechanisms. First, women who have entered the labor force when young have, in their majority, remained active until retirement. Therefore, the future participation rate of cohorts aged 50-60 is likely to approach that of cohorts aged 40-50 (adjusted for some early retirement). Second, there has been a gradual, albeit small, rise in the participation rate of women in their 20s, which is expected to continue (at a decreasing pace) until about 2020.10

27. The current profile of pension payments reflects several influences, among which the growth of real wages in the past and the indexation of benefits. This profile, however, is bound to change over time. Since 1993, and following the proposals in the “Livre blanc sur les retraites” pension benefits (in the regime general) have been adjusted in line with the CPI, instead of according to wages. Accordingly, baseline projections assume that pensions will continue to be indexed to the CPI (although the 1993 Pension Reform leaves the door open for a change in this rule) and that wages will rise in line with productivity growth.

28. In the medium term, aggregate health care expenditure as a proportion of GDP is assumed to fall marginally, while beyond the year 2002, individual health care spending is assumed to rise in line with productivity. This assumption contrasts markedly with the experience of the 1980s and early 1990s, when per capita real public health expenditures after adjustment for demographic changes rose faster than labor productivity. However, to the extent that the reform of public health care announced in 1995 will take its full effect in the coming years, it may not appear implausible.11

Main results

29. The baseline case compares the generational accounts of males and females born in 1995 with the average of those born after 1995 (Table I-5). The projections reflect policies that were in place or had been announced as of 1995; therefore, it takes into account the medium-term fiscal plans contained in the convergence program presented by the previous government. In the baseline scenario (and except where indicated otherwise), the participation rate of women is projected to rise, while that of men is projected to remain constant, and a zero-indexation rule is assumed for pension expenditures, reflecting the fact that accounts are computed in constant prices.

30. The baseline generational accounts for male and female cohorts for the base year 1995 are presented in Table I-6 under the assumptions of a 1 percent productivity growth and discount rates of 3, 4, and 5 percent. A negative value means that the generation is projected to receive more in transfers than it will pay in taxes over its remaining lifetime. Not surprisingly, a life-cycle pattern emerges (see Charts 3 and 4) with working-age generations having the higher tax burden and older generations being net recipients (working-age generations face many years of paying taxes before starting to receive pensions, while some of the benefits they receive indirectly, such as free education for their children, are rather assigned to younger generations).

31. For males in the baseline case (with a 3 percent discount rate), the generational account (i.e., the remaining net tax payments) is about US$145,000 for newborns in 1995,12 rising to a peak of US$330,000 for those who turned 25 in 1995 (who have thus completed their education and have to wait yet some 35 years before retiring). Thereafter, the account falls, becoming negative for those aged 50 in 1995, individuals approaching retirement, and thus a reduced level of income taxes and the receipt of public pension benefits. For females, the lifetime pattern is similar but the accounts at each age are generally much lower than for males. For example, newborn females in 1995 face a net lifetime fiscal burden of some US$115,000, which peaks at US$273,000 at age 25. The fact that accounts for females are lower than males, reflects first, the lower female participation rate and lower pay scale, so that their lifetime gross taxes (mainly labor income and social security taxes) are lower; and second, greater longevity, which tends to increase the present value of their pension receipts.

32. In the baseline scenario, the average net payment burden of future generations is somewhat over one and a half times higher than that faced by the youngest generation alive in 1995 (represented by the 0-4 year old cohort of 1995). If all generations born before 1995 are protected from any change in their lifetime net-tax profile, future generations will have to pay on average about 63 percent more than the youngest “protected” generations, in order to guarantee the ultimate solvency of the government. Assuming that the tax burden of future generations13 will be shared by men and women proportionally to the net-tax burden faced by men and women belonging to the 1995 newborn generation, the lifetime net tax paid by males in future generations would amount to US$235,000, while women would pay US$180,000 over their lifetime.14

33. Generational imbalances are, however, sensitive to the discount and productivity growth rates assumed, as well as to the accounting conventions adopted. Appendix II shows the impact of varying these parameters in the range of 3 percent and 5 percent, and 0.75 percent and 1.5 percent, respectively. Increasing the discount rate to 5 percent, for instance, would reduce the imbalance by 20 percent, while raising productivity by 0.5 percentage points would cut the imbalance by some 10 percent. Although the net present value of all net taxes decreases monotonically with higher interest rates, the change in the imbalance needs not, owing to the uneven distribution of taxes over the lifetimes of current generations (e.g., the impact of a higher discount rate is more marked for women than for men). By contrast, for parameters in the range chosen, the imbalance always decreases when productivity growth increases (mainly because pensions are indexed to CPI and not to wages).15 Changes in the rules regarding the accounting of government wealth or the incidence of corporate income taxes, can also lead to changes in the imbalance of the order of 15–50 percentage points (see Appendix II). Although these figures illustrate the magnitude of the uncertainty associated with any computation of generational accounts, they all point to a worsening of the net tax burden on future generations in France.

D. International Comparisons

34. An interesting question is how France compares with other countries for which there have been standard generational accounting studies. Table I-7 from the OECD (1995) presents comparative generational accounts for other industrial countries: Germany (Raffelheuschen and Walliser, 1995), Italy before the 1995 reform (Franco et al., 1994), Sweden (Hageman and Christoph, 1995), and the United States (Auerbach, Gokhale, and Kotlikoff, 1993). International comparisons of generational accounts require a great deal of caution because the technical and policy assumptions are different across studies (e.g., while figures provided in Table I-7 were based on similar discount and productivity growth rates, accounting conventions including the classification of tax incidence were by no means homogenous). Nonetheless, some interesting patterns emerge. Measured in absolute 1995 U.S. dollars, newborn males in France appear to be facing a lower net tax burden than their counterparts in the United States, Germany, Sweden, and Norway, and a higher one than that facing Italian newborn males before the implementation of the 1995 pension reform; newborn women, by contrast, appear to bear a heavier burden in France than in the United States, Norway, and Italy, while bearing an approximate equivalent burden than their counterparts in Germany and Sweden. For the United States, the higher average net tax burden of newborn generations can in part be attributed to the smaller proportion of public spending directed to social transfers vis-à-vis France. While in France the overall level of taxation, including social contributions, is considerably higher than in the United States, this difference tends to be offset in the calculation of the net tax burden for France by the counterpart of those contributions (i.e., large social transfers)16 and a relatively large outlay related to public hospitals and higher education.

35. In all four countries, there is a generational imbalance against future generations implied by prevailing fiscal policies. The imbalance (measured in percentage differences) appears to be much lower in France than in Italy (326 percent difference before the 1995 pension reform) and the United States (100 percent), but somewhat larger than in Sweden (23 percent) and Germany (25 percent). As noted above, differences in methodology and assumptions could partly explain these differences. Nevertheless, the relatively smaller generational imbalance compared to Italy can be attributed somewhat to, among other factors, a higher debt to GDP ratio in Italy and a more marked demographic change (which prompted a deepening of the reform of the pension system in 1995).17 The relative smaller imbalance visa-vis the United States stems largely from less optimistic assumptions on the projected growth of public expenditure in health care.18 The imbalance vis-à-vis Sweden (a country with a larger welfare system) can be traced to several sources. On the one hand, since 1994 the Swedish economy has undergone a substantial fiscal adjustment aimed at moving the fiscal accounts into surplus by year 2000, and retirement age at 65 years is higher than in France. On the other hand, discrepancies in the recording of social benefits (in good measure recorded as government consumption instead of social transfers) appear to have tilted the imbalance against current generations (whose burden is higher than in France).

E. Generational Accounts of Baby boomers

36. The standard practice of generational accounting includes only future net tax payments, and does not incorporate past net payments of currently living generations. Therefore, the only meaningful comparison of generational accounts is between those of newlyborn generations in the base year and those of future generations, for which lifetime net tax payments are available. Although this way of presenting generational accounts yields insightful results regarding intergenerational imbalances, its interpretation may have a lesser policy relevance than measures aimed at comparing the accounts of those presently living. Indeed, by comparing only the tax burden of unborn generations with that of current children, standard generational accounts fail to address the real political dilemma, which involves a trade-off among living generations. To address this kind of question, it is rather more interesting to compare the net tax burden of, say, current adults (e.g., some cohort of babyboomers), with that of young generations (e.g., those under age 25, who have not fully entered the labor force yet) under the assumption that young generations will bear the same tax burden as all future generations (the standard assumption that all generations alive in 1995 will be “protected” for their whole lifetime is somewhat implausible, given that owing to demographic changes evident already in the early decades of the next century, the heavier burden on future generations will start to be apparent at a relatively early date, and will imply heavy pressures for policy changes).

37. As a yardstick, the generation born in 1950-55 was chosen to represent adult living generations in the computation of the imbalance between “protected” adult generations and young and future generations.19 For this purpose, not only future net transfers were projected (as it is done in the standard exercise), but a retrospective account of past net transfers of selected adult generations was computed.20

38. The calculations reported in Table I-8 indicate that under the present system of taxes and benefits, the projected net tax burden on generations currently aged less than 25 is on average close to two times as large as that faced by those born around 1950, Results vary somewhat, depending on the rate of productivity growth used for comparing the burden on current adult generations and the discount rate, but except for the largest discount rate, the imbalance is significant. If generations are put on equal footing by assuming a 1 percent productivity growth rate, the imbalance is of the order of 90 percent. However, as in many other industrialized countries, productivity growth in France was much higher in 1950-70 than in recent years. Thus, an “historical” measure should weigh early benefits differently from later tax payments, and net taxes instead of being measured in constant francs and later adjusted by a constant rate of growth of productivity, should reflect the size of the economy at different times (i.e., past net taxes should be adjusted for GDP growth over the period). Computing the generational imbalance in this way confirms that future generations would bear a larger burden than current adult generations.

F. Redressing the Generational Imbalance

39. Undoubtedly, the pending demographic transition, with the projected increase in the dependency ratio, is the root cause of most of the intergenerational imbalance. Were the demographic structure to remain unchanged, a significant imbalance would not emerge (Table I-9). In face of the demographic changes, however, delaying changes in the status quo (e.g., regarding that of current adult generations, and in particular concerning pensions) would only increase the cost of adjustment borne out by subsequent generations.21 The recognition of the need for an early adjustment motivated the pension reforms in France designed in the early 1990s and partially implemented in 1993 (mainly affecting the “régime général) and 1996 (with respect to supplementary mandatory pension schemes)—most notably the indexation of pensions to the CPI instead of wages. Table I-10 shows that, were pensions still indexed to wages, e.g., increasing at real rates of 1-1.5 percent a year, the intergenerational imbalance would be almost twice as large, raising to more than 100 percent. This illustration underscores the intergenerational redistribution of resources implied by major pension reforms. Together with that in Table I-9, it suggests that creating incentives so that projected increases in life expectancy are accompanied by longer working lives and contribution periods for a full pension could eliminate most of the problem that is manifest in current projections.

40. Increasing the participation rate (through tightening eligibility requirements for benefits and increasing the taxation of replacement income, including from early retirement) would thus appear to be a policy that could contribute to improving the generational stance of fiscal policy: a higher participation rate not only widens the tax base by raising labor income and GDP, but also reduces pension expenditure as a percent of GDP. A characteristic of the French labor market since the mid-1980s is the relatively low level of labor force participation, particularly for people aged 55–65, while life expectancy continued to increase. As the participation rate of this group of people declined from 31.5 to 16.5 percent, despite a significant increase in the participation rate of women, its share in the active population fell from 18.7 percent in the 1960s to 9.4 percent in 1995 (Dares, 1997). Between 1968 and 1995, participation rates for males aged 60–65 dropped from 68 percent to about 15 percent with only a small change for those aged 55–59. For females aged 60–65, there was a decline from 35 percent to about 13 percent, whereas those in the age group of 55-59 experienced an increase in participation rates from 42-55 percent during the same period. Table I-11 shows that by inducing a gradual rise in the participation rate of those aged 60-65 in 2005-2015 to 40 percent, the imbalance between newborn and future generations is reduced dramatically (vanishing for a discount rate of 4 percent).

Table I-11.

The participation rate of men aged 60-65 gradually increases from 15 percent to 40 percent in 2005-2015; that of women ages 60-65 raises from 13 percent to 40 percent.

41. Although representing an improvement, the lower imbalance reflected in this scenario is achieved mainly by increasing the burden on current young generations. This points to the need for an early increase in the participation rate for people aged 55-65. Table I-12 shows that bringing forward the process, and allowing for a small increase in the participation rate of males aged 55-60, would lead to a greater reduction of the imbalance, with a decline in the burden on future, as well as current young generations. Indeed, Table I-13 shows that such an early action would also cut the imbalance between “babyboomers” and young generations by half.

The participation rate of men aged 60-65 gradually increases from 15 percent to 40 percent starting in year 2000; that of women aged 60-65 raises from 13 percent to 40 percent; a 3-5 percentage increase in the participation rate of men aged 55-60 is also allowed.

42. An increase to 40 percent in the participation rate of those aged 60-65 is consistent with both a three-year increase in the effective retirement age, and a five-year increase in the effective retirement age with fewer working hours in later years—thus leaving ample room for a variety of policy alternatives.22 However, a key measure to achieve this objective would be to consider increasing the number of years required for retiring with a full pension to 45 (adjusting at the same time the formula for computing benefits and the minimum contributive pension). While the 1993 reform included a gradual increase in the number of years from 37 to 40, it fell short of the increase to 42 proposed in the Livre blanc. Its potential effect is thus projected to be quite limited, because more than one half of workers already retire with 40 years of contributions, while the effective pension for those with less than 32.5 years of contributions is determined by the relatively high level of the minimum pension (Briet, et. al, 1995). The increase in the number of years of contributions (if accompanied by an adjustment of the minimum contributive pension) would not require the abolition of the right to retire at 60, but it would create incentives for longer careers and enhance economic activity.23 From a fiscal point of view, the increase in the number of years should be accompanied by a change in the formula for computing benefits (i.e., the number of years of contributions used in the denominator of the formula should increase accordingly).

G. Conclusions

43. This paper attempts to contribute to ongoing discussions about the long-run sustainability of fiscal policy in the face of an aging population in France using a framework designed to capture the intergenerational aspect of the problem. It presents for the first time a set of generational accounts for France with a view to assessing the implications for future generations, given current fiscal rules, of the growth in government spending and debt when the effects of demographic projections and other factors such as the anticipated change in labor force participation rates are taken into account. The calculations reported in this study indicate that the present system of benefits and taxes, if continuously maintained for current adults, is out of balance in the long run from a generational perspective.

44. The size of the standard generational imbalance implies that a lack of fiscal policy adjustment will leave future generations of French citizens facing a lifetime net tax burden that is more than one and a half times as large as those confronting current adult generations based on existing policies. Fortunately, policies can be specified that would help alleviate such an imbalance, in particular those aimed at fostering higher employment and later retirement among the cohorts aged 55-65. This paper has presented such a policy scenario, indicating that an early, but gradual, increase to 40 percent in the participation rate of people aged 60-65—combined with longer pension contribution periods—would sharply reduce the generational imbalance between young and future generations, as well as the imbalance between current adult and young generations, with a decrease in the absolute net tax burden on future generations.

45. A number of caveats call for a careful interpretation of the results presented here. First, the accounts do not reflect private intergenerational transfers, which could contribute to lowering the size of the imbalance. Second, as this is a pure accounting model, no behavioral responses on the part of economic agents are built into the present framework. Finally, the results are sensitive to the long-term economic and demographic assumptions underlying this kind of study. Nonetheless, if interpreted with care, the generational accounts for France as presented in this paper can be used to gauge the extent of direct intergenerational redistribution implied by changing fiscal policies, and thereby assist public decision-making in this area.

APPENDIX I Sources and Data Construction

46. As explained above, average net tax payments for each generation were calculated by distributing aggregate taxes and transfers across population of cohorts according to the age/sex profiles of payments and benefits observed. This required first an estimation of a generational profile (i.e., by individual cohorts of age and gender) of different taxes and benefits in some base year. This was done principally using the 1990 data from surveys conducted by the tax administration department of the Ministry of Finances and INSEE. In a second step, the aggregate weight of each tax or benefit was computed using information in the annual national accounts published by INSEE.

Computation of profiles

47. Chart I-1 presents the age/sex profiles for the five categories of tax considered (personal income tax, property tax, wealth tax, social security tax, and consumption tax). The profiles corresponding to personal income taxes, property taxes, and consumption taxes were based primarily on data from a tax survey conducted by the Ministry of Finance {Enquete sur les revenus fiscaux des menages, 1990). INSEE provided a break down of the results of the 1990 tax survey on these taxes according to the age of the head of households surveyed, but a disaggregation by gender was necessary for the study at hand and was thus inferred from additional sources. This disaggregation is not trivial because the differences in income between men and women vary over the life cycle according to marital status, childbearing, etc. Therefore, in order to take these factors into account, a more detailed disaggregation of the 1984 and 1990 tax surveys (Canceill, 1989, and Campagne, et. al, 1996) and data on the number of individuals at each age living in different types of households (from the 1990 population census) were also used. Canceill (1989) provides several tables showing the average income and personal income tax payments of different types of households (e.g., persons living alone, couples without children, couples with one, two, or three children, households headed by single parents, etc.). Crossing this information with census data on the population living in different types of households (individus selon le sexet Vdge et le mode de vie; INSEE, 1990), permitted to disaggregate by gender the figures by household in the original survey.24 The disaggregation of VAT, and other indirect taxes, was computed by assuming similar consumption profiles for men and women (i.e., assuming that for each age cohort, individuals of both genders pay the same amount of consumption-based taxes).

48. The profiles corresponding to social security contributions were based primarily on the distribution of wages and employment. They were estimated using the age profiles of wages computed by INSEE (Colin, 1995 and Perotin, 1989), and the average proportion between the wages received by men and women found in Bayet (1996).25 The average individual contribution to the social security system was then computed by adjusting the average contribution paid by employed persons to the employment rate of different age and gender cohorts estimated using data in DARES (1997).26

49. The profile corresponding to corporate income taxes and wealth taxes was based on the distribution of financial assets across ages (Enquete sur le patrimoine des families). This, along with the profile of other taxes related to wealth and income (autres impots sur le revenue et le patrimoine) were computed using the age distribution of net wealth found in Lolliviet and Verger (1996), adjusted for the distribution among genders based on figures in Sturrock (1995) and Franco et al. (1993). Following the tack taken in the U.S. Congressional Budget Office study (Sturrock, 1995), incidence of corporate income tax was assumed to be related to net wealth of individuals.

50. The profiles of individualized transfers comprising pensions, health benefits, public expenditure on education, and unemployment benefits (in addition to minimum income benefits, typically the RMI) are shown in Chart I-2. The profiles for expenditure on education were based on the average cost per student (in 1988) for different school ages (Ministere de l’Education Nationale, 1990), attendance rates, and the assumption that these costs were the same for students of both genders. The profiles for expenditure on health care were computed using the chart found in Caussat and Glaude (1993), and data in Mizrahi and Mizrahi (1995). The profile of expenditure on pensions and unemployment benefits was based on figures provided by INSEE (Accardo, 1996).27 The age and gender distribution of pension expenditure found there was smoothed, permitting the elimination of some outliers, especially for old and young ages. Expenditure on minimum support income and other specific social transfers was distributed according to the profile of unemployment benefits.28

Computation of the relative tax weights

51. The assignment of the actual weight of individual taxes and benefits was based on national accounts figures (INSEE, 1996) and followed closely the taxonomy perfected by the French statisticians, which guarantees the internal consistency of fiscal magnitudes. General government resources and uses (see Table I-4) were taken from the national accounts year book “Comptes et Indicateurs Economiques” (Tableau 10.17, Administrations publiques, S60). They were classified as much as possible according to the groups of taxes and transfers listed above, with those items which could not be assigned to any group being lumped into the general government net consumption (see Hagemann and John, 1995 for a rationale behind this choice of aggregation). Government expenditures on services for which beneficiaries could be identified, but which are usually included in government consumption in the sense of the national accounts (e.g., payment of hospital personnel and teachers) were lumped with transfers. This breakdown of government consumption29 and investment was computed based on figures in tables 10.07 and 10.08 of the national accounts yearbook (ventilation fonctionelle de la consommation et de la formation brute de capital fixe des administration publiques). Finally, payments of pensions to government employees were lumped with the pensions to private sector workers, although the contributions which fund them were left at the charge of the government and not shifted to government employees (in the case of the private sector both employers’ and employees’ contributions are shifted to employees).30

52. The taxes and transfers identified in Table I-4 were grouped together in Table I-A1 to show the weight of individual taxes and transfers and of government consumption as percent of GDP for the period 1995-2002. The aggregates’ taxes and transfers for 1996-2002 reflect inter alia the changes in taxation occurred since 1995, and the government goals for 1997-2002. In particular, it assumes a fiscal rule consistent with the government’s convergence targets of a general government deficit below 3 percent after 1997. This fiscal consolidation was assumed to be achieved chiefly through a compression in net government consumption, together with a curbing in health expenditure and unemployment benefits, and a constant tax pressure, except for the gradual reduction in personal income tax included in the 1997 budget (which envisaged a reduction in income taxes totaling 0.8 percent of GDP by the year 2001).

53. The actual average tax payment and transfer receipts of individuals in each age cohort can then easily be computed by scaling the age and gender profiles of individual taxes and transfers such that the respective figures aggregated by cohorts are made consistent with the aggregate weight of the corresponding tax or transfer for a given year.

Computation of generational profiles for the 1950-55 cohorts

54. To compute the past net tax burden of the 1950-55 cohorts, national account flows covering the resources and uses of the public administration in the 1970-95 period were distributed over individual net payment profiles based on the profiles derived for 1995. Health expenditure on health and education in 1950-70 were also estimated from available sources. Unfortunately, while some work on per capita expenditure on health is available, less is available on total expenditure in education (data for the 1950s and 1960s comprise mainly the budget of I’Education Nationale, not covering education spending). The main adjustments on these profiles comprised changes in the age distribution of health expenditure, VAT, and social security taxes (based on Mizhari and Mizhari (1994), and INSEE sources).31 To compare the net payment of the 1950 and 1995 generations, the present value of net taxes paid by the 1950 generation was computed as of 1950 (i.e., flows in 1990 francs were discounted back to 1950), and then adjusted for productivity growth (essentially, adjusting by how far productivity deviated from the period average). Adjusted flows using a L0 percent productivity growth rate (and varying growth rate reflecting historical values) were also computed (see Table I-8).

APPENDIX II Sensitivity Analysis

55. The calculation of the generational accounts is quite sensitive to the assumptions made about economic and demographic projections. Tables I-A2 and I-A3 report the estimated accounts for males and females under alternative assumptions about the parameter values. For a given productivity growth, a higher discount rate tends to lower the generational imbalance as measured by the percentage difference in the present value of taxes paid by future generations and newly born, since it gives a lower weight to future payments.32 On the other hand, the effect of rising productivity is ambiguous, lowering the relative burden of future generations for sufficiently high discount rates, and increasing it for low discount rates. (Indeed, when the generational imbalance is expressed as a ratio of the present value of lifetime incomes, the effect of change in productivity can be reversed.) The intuition for this result is that higher productivity increases the present values of both taxes and transfers. However, because of the life-cycle pattern of consumption and the discounting factor, when the discount rate is sufficiently high, the increase in the present value of taxes (which are paid much earlier in life), outweighs the increase in the present value of benefits. For low enough discount rates, the increase in benefits (which come later in life), together with higher government consumption (which also grows at the productivity rate forever), implies a higher burden on future generations (even after adjusting for “effective” labor).

56. Although one of the main objectives of generational accounting is to free the analysis of public finances from labels that can be misleading, some conceptual problems remain when accounts are actually implemented. The same way standard “deficit” account can be highly misleading when not done according to the principles of national accounts, alternative assumptions regarding inter alia tax incidence can changes results quite substantially. Because generational accounts deal with net flows, differences on how some taxes or benefits are classified do have an impact on the results. These problems are illustrated by adopting alternative assumptions about incidence of particular taxes, as well as regarding the treatment of selected sources of government income associated to its net wealth. To shed some light on the first problem, generational accounts were recalculated under the assumption that corporate income taxes are netted off government consumption (as was done in Hageman and John, 1995) instead of being lumped with other capital income taxes, which incidence was assumed to be proportional to the net wealth of individuals (corporate income tax amount to about 2 percent of GDP). Under this alternative hypothesis, the relative additional burden on future generations vis-à-vis the newly born for the 3 percent discount rate increases from 56 percent to 73 percent (Table I-A4).
