Pay-as-you-go Social Security and the Distribution of Altruistic Transfers

This paper studies the impact of an unfunded social security system on the distribution of altruistic transfers in a framework where savings are due to both life cycle and random altruistic motivations. We show that the effect of social security on the distribution of these transfers depends crucially on the strength of the bequest motive in explaining savings behaviour. We measure this strength by the expected weight that individuals attach to the utility of future generations. On the one hand, if the bequest motive is strong, then an increase in the social security tax raises the bequests left by altruistic parents. On the other hand, when the importance of altruism in motivating savings is sufficiently low, the increase in the social security tax could result in a reduction of the bequests left by altruistic parents under some conditions on the attitude of individuals toward risk and on the relative returns associated with private saving and social security. Some implications concerning the transitional effects of introducing an unfunded social security scheme are also discussed.     

Tax avoidance and intra-family transfers

We study how taxes on intra-family transfers (bequests and gifts) affect parents' transfers to their children. Our focus is on the incentives for tax avoidance. These issues are important for families and their welfare, as well as for governments and their possibilities of raising revenue from transfer taxes. Using a theoretical model, we show how altruistic parents avoid taxes by changing the timing of transfers when inter vivos gifts are taxed separately from bequests (which is the case in many developed countries). The excess burden per tax dollar of the transfer taxes is sometimes infinitely large because of tax avoidance. All tax avoidance is eliminated if bequests and gifts from the same donor are jointly taxed.     

Bequests,gifts, and education: links between intergenerational transfers

We study the channels parents use to make transfers to their children. First, we focus on the relationship between investments in education and property transfers. Second, we turn to how property transfers are divided between inter vivos gifts and bequests. We use a Swedish dataset that is superior to previously used data as it contains information on both gifts and inheritances received from parents. We estimate models for the probabilities of having university education, receiving gifts, and receiving inheritances. In addition, we estimate models for gift and inheritance amounts. We find that the more resources parents have, the higher the likelihood of transfers, and that the correlation between receiving inter vivos gifts and inheritances is very high. Finally, women are more likely to have university education and to receive gifts, and daughters receive gifts of larger amounts than sons, although there are no differences in terms of inheritance.     

Do estate and gift taxes affect the timing of private transfers?

Proposals to alter the estate tax are contentious and have been considered largely in an empirical vacuum. This paper examines time series and cross-sectional variation to identify the effects of estate and gift taxation on the timing of private transfers. The analysis is based on data from the 1989, 1992, 1995, 1998, and 2001 Surveys of Consumer Finances. Legislative activity during this period reduced the tax disadvantage of bequests relative to gifts. Moreover, the magnitude of this reduction differed systematically across identifiable household categories. We find that households experiencing larger declines in the expected tax disadvantages of bequests reduced inter vivos transfers relative to households experiencing small declines in the tax disadvantages of bequests. This finding is consistent with the hypothesis that the timing of transfers is responsive to applicable gift and estate tax rates. The results also provide evidence of a systematic bequest motive for high-wealth households.     

Public pensions and growth

This paper investigates the relationship between the size of an unfunded public pension system and economic growth in an overlapping generation economy, in which altruistic parents finance the education of their children and leave bequests. Unlike the existing literature, we model intergenerational altruism by assuming that children's income during adulthood is an argument of parental utility. Unfunded public pensions can promote growth when families face liquidity constraints preventing them from investing optimally in the education of their children. We consider two alternative ways of financing a public pension system, either by levying social contributions in a lump-sum manner or in proportion to labour income. We find that there is no case for unfunded public pensions in economies where bequests are operative. By contrast, there exists a growth-maximising size of the public pension system in economies where bequests are not operative and individuals are sufficiently patient.     

Economic growth and endogenous intergenerational altruism

The recent literature on the endogenous formation of preferences has emphasized that while some preferences are more conducive to growth than others, economic growth also contributes to the formation of particular tastes [Becker, Gary S. (1996): Accounting for Tastes, Cambridge, Ma.: Harvard University Press]. In this paper, we construct a neoclassical growth model where intergenerational altruism can be endogenously reinforced and entails costly sacrifices on the part of parents to acquire such trait. While the incentives to acquire altruistic traits depend on the economic conditions, in turn altruism determines the level of intergenerational bequests and ultimately the pace of capital accumulation and economic growth. It is shown that intergenerational transfers are driven by a natural degree of altruism at earlier stages of economic growth. Once individuals have satisfied their own physiological constraint in the course of economic development, they devote resources to shaping their altruistic preferences, increasing their social degree of altruism above its natural level. This in turn increases the share of intergenerational transfers and speeds up economic growth.     

Optimal Taxation of Bequests in a Model with Initial Wealth*

We formulate an optimal‐taxation model where parents leave bequests to their descendants for altruistic reasons. In contrast to the standard model, individuals differ not only in earning abilities, but also in initial (inherited) wealth. In this model, a redistributive motive for an inheritance tax – which is equivalent to a uniform tax on all expenditures – arises, given that initial wealth increases with earning abilities. The introduction of the inheritance tax either increases intertemporal social welfare or has an ambiguous effect, depending on whether the external effect related to altruism is accounted for in the social objective.     

Family Transfers Involving Three Generations

Most models of family transfers consider only two generations and focus on two motives: altruism and exchange. They also assume perfect substitution between inter-vivos downward transfers and bequests. Based on French evidence, we show that parent-to-child transfers belong to three distinct categories (investment in child's education, financial assistance, wealth transmission), and advocate a three -generation framework. Thus, transfer behavior of parents toward their children is strongly influenced by the behavior of their own parents. There is also some evidence of the Cox and Stark demonstration effect: parents help their own parents, expecting to receive comparable support from their children. Such behavior can be regarded as indirect reciprocity : the beneficiary does not give back to the initial giver but to a third person of another generation.

私人代际转移动机研究*——基于CHARLS的实证分析

经济学家对代际的物质和时间转移的兴趣引发了人们对转移动机的研究与思考。传统的解释有两种：利他主义与交换互惠。本文利用CHARLS数据，对中国的代际转移动机进行实证研究，发现受传统文化的影响，中国的代际转移更多地表现出利他主义倾向，同时示范效应也有所体现，即个体在照顾父母的同时也在教育自己的孩子赡养父母，以期退休后得到子女的照顾。相对西方国家来说，我国养老金体系的压力较小。但随着老龄化的加剧和生育率的下降，为了缓解未来独生子女赡养双方父母的压力，应当在减少挤出私人代际转移的基础上完善社会保障体系，提高我国老年人口的生活质量。     

The old-age security hypothesis revisited

"Children's altruism toward parents is allowed in a two-overlapping-generations model with endogenous fertility. Parents raise children because, when retired, they expect gifts from their children who are essentially a capital good. Individuals' behavior between generations is examined by analyzing a Nash equilibrium, which is then compared with a social planner's optimal allocation. The pay-as-you-go public pension program is viewed as the optimal gifts from the optimal allocation when the latter is implemented. The effect on fertility of the introduction of a capital market is also analyzed. The validity of the old-age security hypothesis is shown to depend on the parameters of utility and cost functions."     

TRANSFERS FROM MIGRANTS TO THEIR CHILDREN: EVIDENCE THAT ALTRUISM AND CULTURAL FACTORS MATTER

This paper focuses on the determinants of financial inter vivos transfers by migrants living in France in 2003 to their adult children. From a theoretical viewpoint, such transfers may be explained either by altruism or by exchange. While parents would direct their assistance to their less well off children under altruism, support should be channeled to children who live nearby their parents under the exchange motive. We assess the relevance of these two motives using the French PRI survey. Unequal sharing is frequently observed and children are more likely to receive financial transfers when they are in poor circumstance, but not necessarily when living in proximity to parents. We also emphasize the role of cultural factors as determinants of the parental allocation among children. Muslim parents, in particular, are more likely to make transfers to sons than to daughters.     

Bequests, Inter Vivos Transfers, and Wealth Distribution

This paper constructs a heterogeneous agent overlapping generations model with bequests and inter vivos transfers. In the model, households in the same family line behave strategically to determine their consumption, working hours, gifts, and savings. Calibrating the model to the U.S. economy, the paper measures time preference and parental altruism consistent with the economy's capital-output ratio and the size of intergenerational transfers. The model with intergenerational transfers better explains, although not fully, the wealth distribution of the United States. The paper also analyzes the effects of government policy changes on wealth accumulation, distribution, and social welfare.

Choosing between gifts and bequests: How taxes affect the timing of wealth transfers

A number of theories have been advanced to explain the size and timing of intergenerational transfers. One factor only recently explored is the effects of taxes, and in particular the estate tax, on such transfers. This paper represents the first attempt to explore how capital gains and gift taxes, in addition to the estate tax, interact to influence incentives in the timing of transfers. Using estate tax data and exploiting variations in state inheritance, gift, and capital gains tax rates, this paper finds taxes to be an important consideration in the choice between gifts and bequests. In particular, each of capital gains and gift taxes are found to be important determinants of the timing of transfers. These findings are robust to a number of specifications that control for borrowing, charitable bequests, marital status, and the portfolio composition of wealth transfers.     

Social norms and gift behavior: Theory and evidence from Romania

In many developing and transitional countries with limited public income redistribution, inter-household transfers in general, and gifts in particular, are sizable and very important. We use unique Romanian survey data that enables us to isolate pure gifts from other private transfers. We explicitly focus on the importance of community-wide social norms, and find that they indeed play a major role for both the occurrence and the values of gifts. More exactly, our results suggest that the overall predominant gift motive among Romanian households is a norm of reciprocity. Moreover, this norm seems to be dominating for gifts to middle- and high-income households. Even though poor households receive to the same extent, norms of both impure altruism and reciprocity tend to be important. Hence, although the poor may not reciprocate gifts to the same extent as the rich, they still receive, since there is a social norm to give, especially to the poor.     

Fertility,Intra‐Generational Redistribution,and Social Security Sustainability

Incorporating heterogeneity in preference to having children into an overlapping generations model of a small open economy, we examine the effects of changes in the size of pay‐as‐you‐go (PAYG) social security on fertility choices of individuals and population growth of the economy. It is shown that PAYG social security will raise population growth by increasing the number of individuals who have children and the number of children parents have if the system involves redistribution between retirees with different contributions, whereas, if it has no redistribution, PAYG social security does not affect the fertility decisions of individuals.     

Wealth Inequality and Intergenerational Links

Previous work has had difficulty generating household saving behaviour that makes the distribution of wealth much more concentrated than that of labour earnings, and that makes the richest households hold onto large amounts of wealth, even during very old age. I construct a quantitative, general equilibrium, overlapping-generations model in which parents and children are linked by accidental and voluntary bequests and by earnings ability. I show that voluntary bequests can explain the emergence of large estates, while accidental bequests alone cannot, and that adding earnings persistence within families increases wealth concentration even more. I also show that the introduction of a bequest motive generates lifetime savings profiles more consistent with the data.     

Quasi-hyperbolic discounting and social security systems

Hyperbolic discounting has become a common assumption for modeling bounded rationality with respect to individual savings decisions. We examine the effects of hyperbolic discounting on the comparison of alternative social security systems. We show that this form of bounded rationality breaks the equivalence between funded and pay-as-you-go (PAYG) systems established in Sheshinski and Weiss [Sheshinski, E., Weiss, Y., 1981. Uncertainty and optimal social security. Quarterly Journal of Economics 95, 189-206]. Intergenerational transfers within a PAYG economy are usually secured by the social security system and independent of longevity, whereas this is not the case for the funded economy. The savings level under hyperbolic discounting is lower than under exponential discounting [Laibson et al., 1998], but the ratio between the savings level under hyperbolic discounting within a funded economy and a PAYG economy depends on the effectiveness of the commitment devices. It is shown that if individuals are hyperbolic discounters, then in a PAYG economy any change in the mandated level of intergenerational transfers is neutralized by individuals’ voluntary bequests. This does not apply to a funded system.     

should Transfers To Poor Families Be Conditional On School Attendance? A Household Bargaining Perspective*

This article considers the welfare implications of transfers to poor families that are conditional on school attendance and other forms of investment in children's human capital. Family decisions are assumed to be the result of (generalized) Nash bargaining between the two parents. We show that, as long as bequests are zero, conditional transfers are better for children than unconditional transfers. The mother's welfare may also be improved by conditional transfers. Thus, conditioning transfers to bequest‐constrained families have potentially desirable intergenerational and intragenerational welfare effects. Conditioning transfers to unconstrained families make every family member worse off.     

Funded social security and economic growth

This paper investigates the relationship between economic growth and a fully funded social security system in an overlapping generations model with family altruism. It is shown that funded social security may harm growth if there are operative bequests within the family.     

Bequests as signals: Implications for fiscal policy

This paper explores how bequests affect redistributive fiscal policies. The main premise underlying our approach is that bequests act as a signal of parental affection. It is shown that private transfers in the form of bequests may not offset public transfers to a significant extent, even though such private transfers are altruistically motivated and are strictly positive for all but a negligible set of households. This is notable since these conditions are normally believed to yield a fully offsetting response (Ricardian equivalence). We explicitly identify circumstances under which the departure from Ricardian equivalence is large. Notably, the departure may be quite large even when our model is observationally very close to one in which Ricardian equivalence is known to hold (in the sense that children care very little about parental affection).
