This paper compares the steady state outcomes of revenue-neutral changes to the progressivity of the tax schedule. Our economy features heterogeneous households who differ in their preferences and permanent labor productivities, but it does not have idiosyncratic risk. We find that increases in...

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...

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...

How does wealth inequality affect economic growth? Byoungchan Lee answers this question by developing a heterogeneous-agent model and augmenting it with endogenous firm innovation. The novel channel is that rising wealth concentration reduces aggregate demand, which gives firms a disincentive to...

We assess the empirical relevance of different macroeconomic modeling approaches to wealth concentration, using the joint distribution of earnings, capital income and net worth in combination with an OLG model of household heterogeneity. We find large earnings disparities to be the primary...

What drives the dynamics of the racial wealth gap? We answer this question using a dynamic stochastic general equilibrium heterogeneous-agents model. Our calibrated model endogenously produces a racial wealth gap matching that observed in recent decades along with key features of the current...

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...

What are the distributional consequences of tariffs? We build a trade model with incomplete asset markets and households that are heterogeneous in their income, wealth, and labor skill. We increase US tariffs by 5 percentage points and examine several budget-neutral fiscal policies for...

We document asymmetric responses of consumer spending to energy price shocks: Using a multiple-regime threshold vector autoregressive model estimated with Bayesian methods on US data, we find that positive energy price shocks have a larger negative effect on consumption compared with the...
