This article focuses on the estimation of the importance of the precautionary motive in the wealth accumulation decision. We use the micro data set of the De Nederlandsche Bank (DNB) Household Survey (DHS) (CentERdata, Tilburg University), a Dutch household survey containing information on wealth, a subjective measure of income uncertainty and subjective qualitative measures of risk aversion. We find that only a small share of wealth is accumulated for the precautionary motive by the Dutch households. This share of wealth is constant across assets with different degrees of liquidity. The economic downturn of the period 2008 to 2010 seems to affect risk attitudes and precautionary saving. Our findings also suggest that the more risk-averse individuals are those who hold less savings. 相似文献

Precautionary savings models suggest that wealth should rise with income risk. Risk is reduced by means-tested transfers, however, which implies that transfer programs should discourage private wealth accumulation. We offer a comprehensive empirical assessment based on variation across states in the generosity of a number of programs, specifically unemployment insurance and means-tested transfers (Aid to Families with Dependent Children and Food Stamps). We use monthly data on married couples from the Survey of Income and Program Participation (SIPP) to regress wealth on income, income risk, and various measures of transfer generosity. The results support the precaution-ary savings model and reveal moderate negative wealth effects of both unemployment insurance and means-tested transfers, with an elasticity of about −0.18. 相似文献

THE SIZE DISTRIBUTION OF PERSONAL WEALTH IN FRANCE (1977): A FIRST ATTEMPT AT THE ESTATE DUTY METHOD
This paper reports upon the first official application of the estate multiplier method of estimating the wealth distribution to French data. It is based upon a sample of estate duty returns filed during the period September-December 1977. The sampling rate was 5 percent for estates under one million francs, and 100 percent for estates over this level, giving a total of 5031 records. The data available did not permit a breakdown by type of asset. It did, however, permit classification of estates by age, sex, and occupation of decedent. Experiments were conducted using five different sets of mortality multipliers. The set of mortality multipliers judged most appropriate leads to an estimate of aggregate net wealth that is 77 percent of that given in the national balance sheet of the national accounts. Comparison of the distributions of wealth derived in these estimates suggest that the figures are consistent with those found in other countries. 相似文献

In this paper we analyse the saving behaviour of French households by cohort and by age. We exploit two data sets: the Household Budget Surveys (HBS) allow us to define saving as residual of income minus consumption, while the Financial Assets Surveys (FAS) give us saving as changes in wealth. We make use of both financial assets surveys, gross them up using national accounts, and distinguish between “active” and “passive” saving.In France, tax policies appear to be one of the main factors that explain the recent evolution of household saving rates. The complex tax treatment of savings and capital income as well as the way in which households perceive the future of the French retirement pension system (5) also help to explain the composition of active and passive saving. 相似文献

We explore the link between wealth inequality and stability in a two-sector neoclassical growth model with heterogeneous agents. We show that when the inverse of absolute risk aversion (or risk tolerance) is a strictly convex function, wealth inequality is a factor that favors instability. In the opposite case, inequality favors stability. Our characterization also shows that whenever absolute risk tolerance is linear, as when preferences exhibit hyperbolic absolute risk aversion (HARA), wealth heterogeneity is neutral. 相似文献

A mean‐variance framework is applied to Australian household financial portfolios in order to provide estimates of relative risk aversion in the economy. Controlling for various socio‐economic characteristics, we explore whether risk aversion heterogeneity is a function of wealth heterogeneity. In contrast to most studies, we find evidence of very high risk aversion amongst the majority of households of poor households but vastly lower risk aversion amongst the high percentiles in the wealth distribution. Applying a first differences model across three survey waves spanning 2002 to 2010, we find that risk tolerance increases significantly with wealth. Risk tolerance is positively associated with mortgage payments, but rental payments have no relationship. In addition, we found no evidence that holding a university education has any discernible impact on risk aversion. Lastly, we present some preliminary findings as to the impact of financial advice on observed risk aversion. Financial advice is found to accentuating risk aversion, particularly amongst the wealthiest households. The findings have potential implications for the distribution of wealth in Australia that has received renewed interest recently. 相似文献

Conventional one-period utility functions in Economics assume that initial wealth only enters preferences through the definition of final wealth. Consequently, those utility functions most utilized (i.e., exponential and quadratic) have implausible risk characteristics. The authors characterize a new class of utility function whose risk parameters depend upon initial wealth and obtain several desirable results. In particular, investors with quadratic and exponential utility functions can have decreasing risk aversion, and risky assets in a quadratic utility multi-asset environment do not have to be inferior as implied by the traditional framework. 相似文献

This paper examines the optimal trade and hedging decisions of a competitive exporting firm which faces concurrently hedgeable exchange rate risk and non‐hedgeable inflation risk. The macroeconomic interaction between exchange rate and domestic inflation rate risk is described by a state variable. The (strong) correlation is pivotal in determining the optimal risk management. It is shown how optimal hedging strategies are affected by state‐dependent preferences of the firm. The optimal hedge policy is to minimize the variation of marginal utility of final wealth across states of nature instead of minimizing the variance of final wealth. 相似文献

Wealth Inequality and Asset Pricing 总被引:2,自引:0,他引:2
Christian Gollier 《The Review of economic studies》2001,68(1):181-203
In an Arrow–Debreu exchange economy with identical agents except for their initial endowment, we examine how wealth inequality affects the equilibrium level of the equity premium and the risk-free rate. We first show that wealth inequality raises the equity premium if and only if the inverse of absolute risk aversion is concave in wealth. We then show that the equilibrium risk-free rate is reduced by wealth inequality if the inverse of the coefficient of absolute prudence is concave. We also prove that the combination of a small uninsurable background risk with wealth inequality biases asset pricing towards a larger equity premium and a smaller risk-free rate. 相似文献

This article examines the relationship between wealth accumulation and job search dynamics. It proposes a model in which risk‐averse individuals search for jobs, save, and borrow to smooth their consumption. One motivation for accumulating wealth is to finance voluntary quits in order to search for better jobs. Using data on men from the National Longitudinal Survey (1979 cohort), I estimate the individual's dynamic decision problem. The results show that borrowing constraints are tight and reinforce the influence of wealth on job acceptance decisions, namely that more initial wealth and access to larger amounts of credit increase wages and unemployment duration. 相似文献

This article presents the results of the first French efforts to assemble information on the assets and liabilities of the different economic agents. The estimates cover the five-year period 1972–76, with complete balance sheets for the end of 1971, 1972, and 1976. The experimental efforts showed that estimation was feasible. It was possible to bring together the varied, often dispersed, and rarely consistent existing information into an integrated body of aggregates adapted to macroeconomic analysis. The report stresses the importance of articulating the wealth accounts logically with the flow accounts, into a complete, closed, and consistent whole in which the theoretical objectives are well specified. It also points out the limitations of the approach, stemming primarily from the state of the basic statistics relating to wealth. 相似文献

Right-skewed and thick-tailed wealth distributions have been documented as an empirical regularity across space and time. A key mechanism for explaining these distributional features is proportional random growth. We investigate the comparative statics of a well-defined class of random growth models when allowing for stochastically ordered shifts in the wealth return process. An order-contingent monotone comparative statics property is identified, according to which pure increases in risk (e.g. higher volatility of capital returns) foster top wealth concentration whereas first-order stochastically dominated shifts in the return process (induced by e.g. proportional capital income taxation) rather lower inequality at the upper end of the distribution. Our analysis points to the potentially ambiguous effects on top wealth inequality of introducing or modifying capital income tax treatments in the presence of stochastic returns. 相似文献

This paper introduces new techniques to obtain a closed-form rank-by-rank characterization of the equilibrium distribution of wealth in a model in which finitely lived households face uninsurable idiosyncratic investment risk. A central result is that the extent of inequality is determined entirely by two factors. The first factor, household exposure to idiosyncratic investment risk, increases inequality. The second factor, cross-sectional mean reversion of household wealth, decreases inequality. We show that economic mobility is decreasing in inequality and increasing in mean reversion, a result that is consistent with recent empirical observations about the geographic variation in mobility that exists both domestically and internationally. Our approach allows us to examine the implications of increased market completeness in the form of a risk-sharing subgroup of households. We show that a risk-sharing subgroup rises or falls in the equilibrium wealth distribution depending on the level of inequality, and that its presence raises welfare and the rate of wealth accumulation for all households in the economy. 相似文献

This paper studies the risk‐free rate in an overlapping generations economy with bequests. It is shown that the risk‐free rate depends on risk aversion, the elasticity of intertemporal substitution, the share of wealth invested in human wealth, life expectancy, and the preference for bequests. In a standard life‐cycle context, mortality increases the subjective time rate of discount, and thus increases the compensation required to postpone consumption. This latter effect is offset in a bequest‐driven model of the type considered here, leading to much more powerful income effects. In this sense, the model provides a bequest‐motive explanation for the risk‐free rate puzzle put forward by Weil in 1989. 相似文献

The article studies stochastic optimization of an intertemporal consumption model to allocate financial assets between risky and risk-free assets. We use a stochastic optimization technique, in which utility is maximized subject to a self-financing portfolio constraint. The papers in literature have estimated the errors of Euler equations using data from financial markets. It has been shown that it is sufficient to test the first order Euler equation implied by the model. However, they all assume a constant consumption–wealth ratio that constrains the boundary conditions, hence influencing the coefficient of the risk premium. The main contribution of our article is that we drop the assumption of a constant consumption–wealth ratio. We have an analytical solution using a utility maximization model with a stochastic self-financing portfolio. We introduce a terminal condition of wealth with and without bequests. We also simulate the stochastic optimization with a self-financing portfolio, distinguishing risk neutral investors (γ-low) from high risk averse investors (γ-high). We show that the model with bequest has a higher level of wealth and a smoother decline of consumption over time than the model with no bequest at the end of the period. The model with no bequest has the same level of consumption and a sharp fall at the end of the period. Risk averse agents with high return assets have a higher amount of wealth than risk-neutral agents with lower return assets. 相似文献

We create a dynamic theory of endogenous risk sharing groups, with good internal information, and their coexistence with relative performance, individualistic regimes, which are informationally more opaque. Inequality and organizational form are determined simultaneously. Numerical techniques and succinct reformulations of mechanism design problems with suitable choice of promised utilities allow the computation of a stochastic steady state and its transitions. Regions of low inequality and moderate to high wealth (utility promises) produce the relative performance regime, while regions of high inequality and low wealth produce the risk sharing group regime. If there is a cost to prevent coalitions, risk sharing groups emerge at high wealth levels also. Transitions from the relative performance regime to the group regime tend to occur when rewards to observed outputs exacerbate inequality, while transitions from the group regime to the relative performance regime tend to come with a decrease in utility promises. Some regions of inequality and wealth deliver long term persistence of organization form and inequality, while other regions deliver high levels of volatility. 相似文献

Studies on structural education choice models are often inconsistent in choosing whether and how to include a disutility of education, especially in an environment with risk and wealth inequality. We show that adding a disutility term to the education decision, a human capital investment option, is equivalent to assuming a relationship between wealth, risk, and education. Utility gain from education is increasing in the riskiness of future consumption. A riskier environment further propels an agent to choose the human capital investment option that maximizes future income. If the degree of risk increases heterogeneously across multiple human capital investment options, risk aversion and the precautionary savings motive can compound or negate each other depending on which option has a greater increase in risk. 相似文献

This study examines the extent to which heterogeneity of expectations affects wealth distribution, through the use of a standard heterogeneous agent model with uninsured idiosyncratic risk and aggregate uncertainty. A simple stylized model of heterogeneous expectations is considered to demonstrate that the impact of expectations’ heterogeneity on wealth inequality depends nonlinearly on the level and persistence of expectations’ dispersion. It is also shown that the heterogeneity of expectations generated by the empirically validated learning-from-experience model (Malmendier, Nagel, Q J Econ 2016) has a moderate but ambiguous impact on the distribution of wealth. The effect is sensitive to the calibration of the macroeconomic and learning parts of the model. 相似文献
