How are the gains and losses from trade distributed across individuals within a country? First, we document that tradable goods and services constitute a larger fraction of expenditures for low-wealth and low-income households. Second, we build a trade model with nonhomothetic preferences—to...

We study long-run correlations between safe real interest rates in the U.S. and over 20 variables that have been hypothesized to influence real rates. The list of variables is motivated by the familiar intertermporal IS equation, by models of aggregate savings and investment, and by reduced form...

In the aftermath of consumer debt-induced recession, policymakers have questioned whether fiscal stimulus is effective during the periods of high consumer indebtedness. This study empirically investigates this question. Using detailed data on Department of Defense spending for the 2006-2009...

U.S. consumption has gone through steep ups and downs since 2000. We quantify the statistical impact of income, unemployment, house prices, credit scores, debt, financial assets, expectations, foreclosures, and inequality on county-level consumption growth for four subperiods: the "dot-com...

This paper studies short-run wealth mobility in a heterogeneous agents, incomplete-markets model. Wealth mobility has a “hump-shaped” relationship with the persistence of the stochastic process governing labor income: low when shocks are close to i.i.d. or close to a random walk, and higher...

We reconcile the large and persistent racial wealth gap with the smaller racial earnings gap, using a general equilibrium heterogeneous-agents model that matches racial differences in earnings, wealth, bequests, and returns to savings. Given initial racial wealth inequality in 1962, our model...

We study the effects on inequality of a “Piketty transition” to zero growth. In a model with a worker-capitalist dichotomy, we show first that the relationship between inequality (measured as a ratio of incomes for the two types) and growth is complicated; zero growth can raise or lower...

How can we measure the welfare benefit of ongoing stabilization policies? We develop a methodology to calculate the welfare cost of business cycles taking into account that observed consumption is partially smoothed. We propose a decomposition that disentangles consumption in a mix of...

What are the consequences of a nationwide reform of a transfer system based on means-testing toward one of unconditional transfers? I answer this question with a quantitative model to assess the general equilibrium, inequality, and welfare effects of substituting the current US income security...

This paper studies sunspot fluctuations in a model with heterogeneous households. We find that wealth inequality reduces the degree of increasing returns needed to produce indeterminacy, while wage inequality increases it. When the model is calibrated to match the joint distribution of hours,...
