At least three types of precautionary motives are directly relevant to an agent's demand for assets. (I.) The precautionary saving motive, or prudence, can cause an agent to respond to a risk by accumulating more wealth. (II.) The desire to moderate total exposure to risk, or temperance, can...

Multi-sector sticky price models have surprising implications when durable goods have flexible prices. While in actual data the production of virtually all durables exhibits strong negative responses to monetary contractions, in dynamic general equilibrium models a monetary contraction causes...

In this paper, we derive and estimate relationships governing variable utilization of capital and labor for a firm solving a dynamic cost-minimization problem. Our method allows for (i) imperfect competition, (ii) increasing returns to scale, (iii) unobserved changes in utilization, (iv)...

Efficiency wage models of the effort elicitation type have important implications for labor market dynamics. These models have a wide array of discontinuous sunspot equilibria driven by extraneous variables, in addition to well-behaved equilibria characterized by continuous, slowly adjusting...

Individuals' preferences underlying most economic behavior are likely to display substantial heterogeneity. This paper reports on direct measures of preference parameters relating to risk tolerance, time preference, and intertemporal substitution. These experimental measures are based on survey...

Economic theory assigns a central role to risk preferences. This paper develops a measure of relative risk tolerance using responses to hypothetical income gambles in the Health and Retirement Study. In contrast to most survey measures that produce an ordinal metric, this paper shows how to...

This paper analyzes the effects of government debt and income taxes on consumption and saving in a world of infinitely-lived households having uncertain and heterogeneous incomes. The special structure of the model allows exact aggregation across households despite incomplete markets. The...

The effect of uninsured labor income risk on the joint saving/portfolio composition decision is analyzed using new techniques from the theory of multiple risk-bearing. Applying this analysis, the effect of labor income taxes on the demand for risky securities is considered. It is well known that...

This paper examines how aversion to risk and aversion to intertemporal substitution determine the strength of the precautionary saving motive in a two-period model with Selden/Kreps-Porteus preferences. For small risks, we derive a measure of the strength of the precautionary saving motive which...

The theory of precautionary saving is shown in this paper to be isomorphic to the Arrow-Pratt theory of risk aversion, making possible the application of a large body of knowledge about risk aversion to precautionary saving, and more generally, to the theory of optimal choice under risk. In...
