Reverse Capital Deepening and the Numeraire: a note

The orthodox theory of precautionary saving fails to distinguish risk from uncertainty, and thus assumes the existence of a probability distribution governing an individual's future income prospects. The individual is assumed to be motivated to save by the dispersion in the distribution of future income, and researchers have therefore attempted to correlate saving with income variance. However, the empirical evidence tends to refute any such correlation. This paper proposes a concept of futility to describe actions that cannot affect the external environment, and demonstrates that precautionary saving in the orthodox sense is futile inasmuch as saving cannot alter the dispersion of resources around an expected future value. Despite the inadequacy of orthodox theory, the theory is perpetuated because even futile behaviour is consistent with the neoclassical notion of rationality. The retention of an invalid theory of precaution provides a faulty basis for both empirical research and policy analysis; thus, the present paper suggests an alternative approach to precaution based on the work of Knight and Shackle, in which decisions are made under conditions of uncertainty rather than risk.     

The surprisingly low importance of income uncertainty for precaution

While it is common to use income uncertainty to explain household saving decisions, there is much disagreement about the importance of precautionary saving. This paper suggests that income uncertainty is not an important motive for saving, although households do have other precautionary reasons to save. Using a question from the Survey of Consumer Finances that asks how much households want for precautionary purposes, this paper shows that expressed household preferences, and liquid savings, are much lower than predicted by standard modeling assumptions. Households rarely list unemployment as a reason to save. Perceived income uncertainty does not affect liquid savings or precautionary preferences. Neither does being in an occupation with higher income volatility. Instead, households seem very concerned with expenditure shocks.     

The effect of precautionary saving on consumption in Sweden

Uncertainty concerning future income lowers consumption. This is often called the precautionary demand for savings. In this paper the existence of precautionary savings. In this paper the existence of precautionary saving is investigated using Swedish data for the years 1973–1992. As there are no variables for consumers' uncertainty a proxy is used. Assuming an underlying distribution of attitudinal data, a variance series is derived. Including the proxy in different specifications of the consumption function, indication of precautionary saving can be found. As a result, no uncertainty would raise consumption by 4.9%.     

Family Altruism and Incentives

This paper characterizes the pattern of intergenerational transfers that emerges in an altruistic model of the family when children's effort is explicitly made endogenous and parents have imperfect information on the stochastic income realizations of their children. It is shown that, if parents can credibly commit to a pattern of transfers, they will choose not to compensate children in bad outcomes as much as predicted by the standard (no uncertainty, no asymmetric information) dynastic model of the family. In this context, Ricardian equivalence holds whenever non‐negativity constraints are not binding.     

Raising productivity with pension premium

We argue that parents underinvest in growing their own children's capability in the absence of property rights over their future income, and that causes economic waste. No amount of collaborative choice among contemporary adults for public education could eliminate it because they face a resource constraint set by their predecessors. Such intergenerational dependence requires an intergenerational contract instead. It involves rewarding parents with a pension premium tied to their own children's taxable income paired with a matching subsidy to parental expenditure. We show how it fully internalizes the intergenerational externality, related to parenting, to eliminate economic waste and, thereby, to raise labor productivity and economic welfare. Our quantitative analysis of a baseline economy reveals significant welfare gains in economies with population ageing coupled with a low degree of parental care for children's future welfare and high returns to parental expenditure on children.     

Uncertain Pension Income and Household Saving

This paper investigates the relationship between household saving and pensions, and estimates both the displacement effect of pensions on private saving and the precautionary saving effect due to uncertainty in pension income. I estimate the savings equation implied by a simple life‐cycle model featuring income uncertainty using survey data for Dutch households, with subjective expectations on pension benefits and uncertainty. Exploiting exogenous variation due to pension fund performance, I find that households save significantly more due to uncertainty in pension income. Not controlling for uncertainty biases the estimated displacement effect of pensions on private savings towards zero.     

A new interpretation for the precautionary saving motive: a note

This paper proposes a new interpretation for the precautionary saving motive: when future income is uncertain, agents increase saving in order to cause a reduction in the disutility due to uncertainty. Furthermore, the paper shows that the usual necessary and sufficient condition for precautionary saving is the condition ensuring this effect to occur and gives new insights into the relationship between risk aversion indexes and precautionary saving.      

Precautionary saving in the presence of labor income and interest rate risks

This paper deals with the classic issue of precautionary saving in a standard two-period setting. The literature has identified conditions on the individual??s utility function under which either labor income uncertainty or interest-rate uncertainty can lead to positive precautionary saving. We allow for both sources of uncertainty simultaneously. We extend the Jensen inequality from one risk to two positively quadrant dependent risks. The main result of the paper is that ??positive quadrant dependent?? uncertainty raises saving if and only if ??partial relative prudence?? is larger than 2. We characterize the condition that ??partial relative prudence?? exceeds 2 via preferences over simple binary lotteries, in the style of Eeckhoudt and Schlesinger (Am Econ Rev 96:280?C289, 2006).     

Intergenerational transmission of education in China: New evidence from the Chinese Cultural Revolution

This paper estimates the effect of parental education on children's education by using instruments generated by the Chinese Cultural Revolution, and further explores the mechanisms of this causal relationship. Several important findings stand out from our empirical analyses. We find a larger intergenerational persistence in education for higher level in urban areas but for a lower level of education in rural areas. The main results from instrumental variable estimation show that the nurture effect is larger and more significant for fathers than for mothers. A deeper investigation of the mechanism behind this nurture effect informs us that a father's education passes on to his children's education partly through the income channel. Another notable finding is that even after controlling for fathers’ income, parental education still has a significantly positive effect on children's education through the nurture effect. This indicates that beyond the income channel, there may exist other channels such as better home environment, which deserve to be explored in future research.     

双重不确定性下的流动劳动力储蓄行为--对“中国储蓄之谜”的另一种解读

基于2012年广东省调查数据,从收入不确定性和支出不确定性两个方面研究预防性储蓄对流动劳动力储蓄行为的影响,发现：（1）流动劳动力储蓄行为与收入水平显著相关,高储蓄率是通过“节衣缩食”、维持基本生存消费来实现;（2）流动劳动力储蓄行为与收入不确定性相关,技能程度、签订劳动合同、劳动合同期限年限对流动劳动力储蓄率有显著影响;（3）流动劳动力储蓄行为与支出不确定性相关,在流入地购买社保、户口性质等对流动劳动力储蓄率有显著影响。研究结果拓展了“中国储蓄之谜”的研究领域,为加快实现流动人口城镇化、推动流动劳动力市民化融入提供了初步的经验证据。     

Precautionary wealth accumulation: evidence from Canadian microdata

Abstract .  This paper estimates the effect of labour income uncertainty on wealth accumulation using two data sources. Wealth information is obtained from the master files of the new Canadian Survey of Financial Security 1999 (SFS). Labour income risk proxies are constucted by industry using the Canadian Survey of Labour and Income Dynamics (SLID) between 1996 and 2001. The empirical results suggest the presence of a strong precautionary saving motive among Canadian households for broad definitions of wealth. Furthermore, consistent with the buffer-stock-saving model, the level of precautionary funds significantly increases when households face liquidity constraints.     

Wage arrears uncertainty and precautionary saving in Russia1

Wage arrears are widespread in Russia, and are one of the main causes of uncertainty in the labour market. In this paper, we use the Russian Longitudinal Monitoring Survey over the period 1994–98 to construct a new and improved measure of household income risk, based on the uncertainty due to wage arrears. We then use this measure of uncertainty to test the precautionary saving hypothesis, according to which households save to self‐insure against risk. We find significant evidence of additional saving by those households whose head is more likely to suffer from wage arrears one year hence. This suggests the existence of a strong precautionary saving motive.     

Prudent consumers: New evidence from the Consumer Expenditure Survey

Using Consumer Expenditure Survey data from 1986 to recent years, this study examines whether or not the precautionary saving motive is an important force governing consumer behavior. A time series model is obtained by aggregating a log-linearized Euler equation across households, in which the cross-sectional variance of consumption growth represents income uncertainty. The test uses an alternative measure of consumption that excludes some problematic expenditure items from the conventional measure and finds strong evidence for the presence of the precautionary motive. This result is in sharp contrast with the findings of previous cross-sectional estimations using the same data set. It is argued that cross-sectional estimations may be seriously affected by measurement errors whereas the current estimation is not.     

Intergenerational transfer,human capital and long-term growth in China under the one child policy

We suggest that the demographic changes caused by the one child policy (OCP) may not harm China's long-term growth. This is because of the higher human capital accumulation induced by the intergenerational transfer arrangements under China's poor-functioning formal social security system. Parents raise their children and depend on them for support when they reach an advanced age. A decrease in the number of children prompted by the OCP results in parents investing more in their children's education to ensure retirement consumption. In addition, decreased childcare costs strengthen educational investment through an income effect. Using a calibrated model, a benchmark with the OCP is compared to three counterfactual experiments without the OCP. Output in 2025 without OCP decreases about 4% under moderate estimates. The output gain comes from a greatly increased educational investment driven by fewer children (11.4 years of schooling rather than 8.1). Our model sheds new light on the prospects of China's long-term growth by emphasizing the OCP's growth enhancing role through human capital formation under intergenerational transfer arrangements.     

HOW CERTAIN ARE DUTCH HOUSEHOLDS ABOUT FUTURE INCOME? AN EMPIRICAL ANALYSIS

The precautionary saving literature shows that income uncertainty increases savings and wealth. To estimate the magnitude of this effect, we need a measure of income uncertainty. This paper empirically analyzes subjective income uncertainty in The Netherlands. Data come from a large Dutch household survey. We measure income uncertainty by asking questions on expected household income in the next twelve months. First, we describe the data and investigate the relationship between the measure of income uncertainty and a number of household characteristics. Controlling for information on expected income changes, we find strong relationships between labor-market characteristics and the subjective income uncertainty as reported by the heads of the households. Second, we compare income uncertainty in The Netherlands with income uncertainty in the U.S. and Italy. It becomes evident that perceived income uncertainty is smaller in The Netherlands than it is in the U.S.     

Aggregate savings when individual income varies

This paper examines aggregate savings in a general equilibrium model where infinitely lived households face volatile (and possibly uncertain) income paths, hold a risk-free asset, and face a borrowing constraint. I first show that the equilibrium capital stock in an economy without uncertainty, but where individual income varies, can be larger than in an economy where each household's income is constant. When individual income is stochastic and uninsurable, the equilibrium capital stock is always larger than when income is constant. This additional capital accumulation has sometimes been interpreted as precautionary savings, but I argue that much of the additional savings are generated by permanent-income motives in combination with strict borrowing constraints.     

Health insurance and precautionary saving: A structural analysis

Starr-McCluer (1996) documented an empirical finding showing that US households covered by health insurance saved more than those without coverage, which is inconsistent with the standard consumption–saving theory. This study conducts a structural analysis and suggests that institutional factors, particularly, a social insurance or safety net system and an employment-based health insurance system, can account for this puzzling finding. A dynamic equilibrium model is built that combines these two institutions with heterogeneous agents making endogenous decisions regarding saving, the labor supply and health insurance when they are young. The model, in which agents save in a precautionary manner, can generate Starr-McCluer?s empirical finding. The result implies that Starr-McCluer?s results are not inconsistent with the standard theory of saving under uncertainty, but it does indicate that the standard saving regression model is unable to reveal the precautionary saving motive. Counterfactual experiments are performed to provide implications for empirical analyses.     

Precautionary saving under liquidity constraints: evidence from Italy

I empirically investigate precautionary savings under liquidity constraints in Italy using a unique indicator of subjective variance of income growth to measure the strength of the precautionary motive for saving, and a variety of survey-based indicators of liquidity constraints. The main contribution of the paper is twofold. First of all, I attempt to differentiate between the standard precautionary saving caused by uncertainty from the one due to liquidity constraints using an endogenous switching regression approach, which allows me to cope with endogeneity issues associated with sample splitting techniques. Second, I move one step further with respect to previous studies on consumption behaviour by taking explicitly expected liquidity constraints into account. I eventually found the precautionary motive for savings to be stronger for those households who face binding constraints, or expect constraints to be binding in the future. Indeed, a complementarity relation exists between precautionary savings and liquidity constraints.     

Intergenerational Correlations of Extreme Right‐Wing Party Preferences and Attitudes toward Immigration

In this paper, we analyze the importance of parental socialization on the development of children's far right‐wing preferences and attitudes toward immigration. Using longitudinal data from Germany, our intergenerational estimates suggest that the strongest and most important predictor for young people's right‐wing extremism are their parents' right‐wing extremist attitudes. While intergenerational associations in attitudes toward immigration are equally high for sons and daughters, we find a positive intergenerational transmission of right‐wing extremist party affinity for sons, but not for daughters. Compared to the intergenerational correlation of other party affinities, the high association between fathers' and sons' right‐wing extremist attitudes is particularly striking.     

Precautionary retirement and precautionary saving

The paper analyzes the lifetime utility maximization problem of an agent who chooses her saving and timing of retirement in the presence of labor income risk in a simple setting where a pure redistributive pension scheme is in place. In this context, a precautionary motive for retirement, which pushes old workers to replace an uncertain labor income with certain pension payments, and to retire early is identified. The conditions for precautionary retirement and saving to arise are then characterized and interpreted in two settings. In the first setting, utility only depends on income, and a sufficiently low level of absolute prudence is necessary for precautionary retirement. A sufficiently high level is necessary however for precautionary saving, which can coexist with precautionary retirement only for intermediate values of absolute prudence. In the second setting, agent utility also depends on leisure, and three conditions allow the precautionary motive for retirement and saving to jointly operate: prudence, an index of absolute prudence sufficiently low and cross-prudence in leisure.
