How do movements in the distribution of income and wealth affect the macroeconomy? We analyze this question using a calibrated version of the stochastic growth model with partially uninsurable idiosyncratic risk and movements in aggregate productivity. Our main finding is that, in the stationary stochastic equilibrium, the behavior of the macroeconomic aggregates can be almost perfectly described using only the mean of the wealth distribution. This result is robust to substantial changes in…

When Does Heterogeneity Matter

How do movements in the distribution of income affect the macroeconomy? Krusell and Smith (1998) analyzed this question in a neoclassical growth model, and their results show that the

Information and Wealth Heterogeneity in the Macroeconomy

We document systematic differences in macroeconomic expectations across U.S. households and rationalize our findings with a theory of information choice. We embed this theory into an

Heterogeneous expectations and the distribution of wealth

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

A Comprehensive Quantitative Theory of the U . S . Wealth Distribution

This paper employs a benchmark heterogeneous-agent macroeconomic model to examine a number of plausible drivers of the rise in wealth inequality in the U.S. over the last forty years. We find that

INCOME AND WEALTH HETEROGENEITY, PORTFOLIO CHOICE, AND EQUILIBRIUM ASSET RETURNS

We derive asset-pricing and portfolio-choice implications of a dynamic incomplete-markets model in which consumers are heterogeneous in several respects: labor income, asset wealth, and preferences.

EQUILIBRIUM ASSET PRICES AND SAVINGS OF HETEROGENEOUS AGENTS IN THE PRESENCE OF INCOMPLETE MARKETS AND PORTFOLIO CONSTRAINTS

We study the quantitative properties of a dynamic general equilibrium model. Agents face both idiosyncratic and aggregate income risk, state-dependent borrowing constraints that bind occasionally,

Borrowing Constraints and Aggregate Economic Activity

A model of aggregate economic activity is formulated which enmphasizes the effects of borrowing constraints in the presence of uninsurable risk. An important determinant of current income level is

Precautionary Saving and Social Insurance

Micro data studies of household saving often find a significant group in the population with virtually no wealth, raising concerns about heterogeneity in motives for saving. In particular, this

Evaluating the Effects of Incomplete Markets on Risk Sharing and Asset Pricing

We examine an economy in which agents cannot write contracts contingent on future labor income. The agents face aggregate uncertainty in the form of dividend and systematic labor income risk, and

This paper examines entrepreneurship in order to analyze, first, the degree to which the opportunity to start or own a business affects the household's saving behavior and the implication of this

Do the implications for business cycle issues change when we switch from studying innnitely lived, representative-agent models to more sophisticated demographic structures with nitely lived agents?
