The Dynamics of the Racial Wealth Gap
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 attributes the slow convergence of the racial wealth gap primarily to earnings, with much smaller roles for bequests or returns to savings. Cross-sectional regressions of wealth on earnings using simulated data produce the same racial gap documented in the literature. One-time wealth transfers have only ...

Benchmarking Global Optimizers
We benchmark six global optimization algorithms by comparing their performance on challenging multidimensional test functions as well as on a method of simulated moments estimation of a panel data model of earnings dynamics. Five of the algorithms are from the popular NLopt open-source library: (i) Controlled Random Search with local mutation (CRS), (ii) Improved Stochastic Ranking Evolution Strategy (ISRES), (iii) Multi-Level Single-Linkage (MLSL), (iv) Stochastic Global Optimization (StoGo), and (v) Evolutionary Strategy with Cauchy distribution (ESCH). The sixth algorithm is TikTak, which ...

Financial development and long-run volatility trends
Countries with more developed financial markets tend to have significantly lower aggregate volatility. This relationship is also highly non-linear starting from a low level of financial development the reduction in aggregate volatility is far more significant with respect to financial deepening than when the financial market is more developed. We build a fully-edged heterogeneous-agent model with an endogenous financial market of private credit and debt to rationalize these stylized facts. We show how financial development that promotes better credit allocations under more relaxed borrowing ...

Consumption in the Great Recession: The Financial Distress Channel
During the Great Recession, the collapse of consumption across the US varied greatly but systematically with house-price declines. Our message is that household financial health matters for understanding this relationship. Two facts are essential for our finding: (1) the decline in house prices led to an increase in household financial distress (FD) prior to the decline in income during the recession, and (2) at the zip-code level, the prevalence of FD prior to the recession was positively correlated with house-price declines at the onset of the recession. We measure the power of the ...

The Effects of Macroeconomic Shocks: Household Financial Distress Matters
This paper investigates how, and how much, household financial distress (FD), arising from allowing debts to go unpaid, matters for the aggregate and cross-sectional consumption responses to macroeconomic risk. Through a battery of structural models, we show that FD can affect consumption responses through three channels: (1) as another margin of adjustment to shocks (direct channel); (2) because its persistence implies a significant degree of preference heterogeneity (indirect channel); and (3) because it can exacerbate macroeconomic risks whenever it is more severe in the hardest-hit ...

Preferences over the Racial Composition of Neighborhoods: Estimates and Implications
We estimate the parameters of a dynamic, forward-looking neighborhood choice model in 197 metro areas where households have preferences over the racial composition of neighborhoods. Our inclusion of multiple metro areas in the estimation sample enables us to develop a new, shift-share IV strategy to estimate the impact of the racial composition of neighborhoods on location choice that relies only on across-metro comparisons of similarly situated neighborhoods. For the “shift,” we use national data to determine the probabilities different types of households live in different neighborhoods ...

Household Financial Distress and the Burden of “Aggregate” Shocks
The goal of this paper is to show that household-level financial distress (FD) varies greatly, meaning there is unequal exposure to macroeconomic risk, and that FD can increase macroeconomic vulnerability. To do this, we first establish three facts: (i) regions in the U.S. vary significantly in their "FD-intensity," measured either by how much additional credit households therein can access, or in how delinquent they typically are on debts, (ii) shocks that are typically viewed as "aggregate" in nature hit geographic areas quite differently, and (iii) FD is an economic "preexisting ...

The Effects of Macroeconomic Shocks: Household Financial Distress Matters
When a macroeconomic shock arrives, variation in household balance-sheet health (captured by the presence of financial distress "FD"), leads to differential access to credit, and hence a distribution of consumption responses. As we document, though, over the past two recessions, households in prior FD also experienced macroeconomic shocks more intensely than others, leading to a distribution of shock severity. Thus, quantifying the importance of both dimensions of heterogeneity (FD or shock-severity) for consumption requires a structural model. We find that heterogeneity in FD matters more ...
