A Parsimonious Macroeconomic Model for Asset Pricing

ECONOMETRICA, Issue 6 2009
Fatih Guvenen
I study asset prices in a two-agent macroeconomic model with two key features: limited stock market participation and heterogeneity in the elasticity of intertemporal substitution in consumption (EIS). The model is consistent with some prominent features of asset prices, such as a high equity premium, relatively smooth interest rates, procyclical stock prices, and countercyclical variation in the equity premium, its volatility, and in the Sharpe ratio. In this model, the risk-free asset market plays a central role by allowing non-stockholders (with low EIS) to smooth the fluctuations in their labor income. This process concentrates non-stockholders' labor income risk among a small group of stockholders, who then demand a high premium for bearing the aggregate equity risk. Furthermore, this mechanism is consistent with the very small share of aggregate wealth held by non-stockholders in the U.S. data, which has proved problematic for previous models with limited participation. I show that this large wealth inequality is also important for the model's ability to generate a countercyclical equity premium. When it comes to business cycle performance, the model's progress has been more limited: consumption is still too volatile compared to the data, whereas investment is still too smooth. These are important areas for potential improvement in this framework. [source]


Social Desirability of Earnings Tests

GERMAN ECONOMIC REVIEW, Issue 2 2008
Helmuth Cremer
Earnings tests; social security; age-related taxation; retirement age Abstract. In many countries, pension systems involve some form of earnings test; i.e. an individual's benefits are reduced if he has labor income. This paper examines whether or not such earnings tests emerge when pension system and income tax are optimally designed. We use a simple model with individuals differing both in productivity and in their health status. The working life of an individual has two ,endings': an official retirement age at which he starts drawing pension benefits (while possibly supplementing them with some labor income) and an effective age of retirement at which professional activity is completely given up. Weekly work time is endogenous, but constant in the period before official retirement and again constant (but possibly at a different level), after official retirement. Earnings tests mean that earnings are subject to a higher tax after official retirement than before. We show under which conditions earnings tests emerge both under a linear and under a non-linear tax scheme. In particular, we show that earnings tests will occur if heterogeneities in health or productivity are more significant after official retirement than before. [source]


Does nonagricultural labor relax farmers' credit constraints?

AGRICULTURAL ECONOMICS, Issue 2 2009
Evidence from longitudinal data for Vietnam
Rural labor markets; Linkages; Credit constraints; Vietnam Abstract We examine the relationship between participation in nonagricultural labor activities and farming production decisions, focusing on the use of inputs. Using longitudinal data for Vietnam from 1993 to 1998, we find that households engaged in nonagricultural labor spend significantly more on seeds, services, hired labor, and livestock inputs. This is consistent with the hypothesis that nonagricultural labor income relaxes credit constraints to farming. [source]


Intergenerational Allocation of Government Expenditures: Externalities and Optimal Taxation

JOURNAL OF PUBLIC ECONOMIC THEORY, Issue 1 2008
KAZI IQBAL
This paper studies optimal capital and labor income taxes when the benefits of public goods are age-dependent. Provided the government can impose a consumption tax, it can attain the first-best resource allocation. This involves the uniform taxation of the cohorts' labor income and a zero capital income tax. With no consumption tax and optimally chosen government spending, labor income should be taxed nonuniformly across cohorts and the capital income tax should be nonzero. Deviations of the public goods from their respective optima create distortions. These affect the labor supply decisions of both cohorts and capital accumulation, providing a further reason to tax (or subsidize) capital income. [source]


Optimal Monetary Policy, Taxes, and Public Debt in an Intertemporal Equilibrium

JOURNAL OF PUBLIC ECONOMIC THEORY, Issue 3 2002
Bertrand Crettez
This article is devoted to a study of the optimal monetary and fiscal policies within the framework of an overlapping generations model with cash-in-advance constraints. We first characterize the intertemporal equilibrium. Then we show how to decentralize the optimal growth path using available policy instruments (i.e., labor income and capital taxes, public debt, money supply). Between the four instruments: wages and capital taxes, debt and monetary policy, one is redundant among the three last which implies that the Friedman Rule is only a special case. [source]


Portfolio Choice and Life Insurance: The CRRA Case

JOURNAL OF RISK AND INSURANCE, Issue 4 2008
Huaxiong Huang
We solve a portfolio choice problem that includes life insurance and labor income under constant relative risk aversion (CRRA) preferences. We focus on the correlation between the dynamics of human capital and financial capital and model the utility of the family as opposed to separating consumption and bequest. We simplify the underlying Hamilton,Jacobi,Bellman equation using a similarity reduction technique that leads to an efficient numerical solution. Households for whom shocks to human capital are negatively correlated with shocks to financial capital should own more life insurance with greater equity/stock exposure. Life insurance hedges human capital and is insensitive to the family's risk aversion, consistent with practitioner guidance. [source]


Consumption, Aggregate Wealth, and Expected Stock Returns

THE JOURNAL OF FINANCE, Issue 3 2001
Martin Lettau
This paper studies the role of fluctuations in the aggregate consumption,wealth ratio for predicting stock returns. Using U.S. quarterly stock market data, we find that these fluctuations in the consumption,wealth ratio are strong predictors of both real stock returns and excess returns over a Treasury bill rate. We also find that this variable is a better forecaster of future returns at short and intermediate horizons than is the dividend yield, the dividend payout ratio, and several other popular forecasting variables. Why should the consumption,wealth ratio forecast asset returns? We show that a wide class of optimal models of consumer behavior imply that the log consumption,aggregate wealth (human capital plus asset holdings) ratio summarizes expected returns on aggregate wealth, or the market portfolio. Although this ratio is not observable, we provide assumptions under which its important predictive components for future asset returns may be xpressed in terms of observable variables, namely in terms of consumption, asset holdings and labor income. The framework implies that these variables are cointegrated, and that deviations from this shared trend summarize agents' expectations of future returns on the market portfolio. [source]


Structure of the optimal income tax in the quasi-linear model

INTERNATIONAL JOURNAL OF ECONOMIC THEORY, Issue 1 2007
Nigar Hashimzade
H21; H24 Existing numerical characterizations of the optimal income tax have been based on a limited number of model specifications. As a result, they do not reveal which properties are general. We determine the optimal tax in the quasi-linear model under weaker assumptions than have previously been used; in particular, we remove the assumption of a lower bound on the utility of zero consumption and the need to permit negative labor incomes. A Monte Carlo analysis is then conducted in which economies are selected at random and the optimal tax function constructed. The results show that in a significant proportion of economies the marginal tax rate rises at low skills and falls at high. The average tax rate is equally likely to rise or fall with skill at low skill levels, rises in the majority of cases in the centre of the skill range, and falls at high skills. These results are consistent across all the specifications we test. We then extend the analysis to show that these results also hold for Cobb-Douglas utility. [source]
