A quantitative theory of unsecured consumer credit with risk of default
The authors study, theoretically and quantitatively, the general equilibrium of an economy in which households smooth consumption by means of both a riskless asset and unsecured loans with the option to default. The default option resembles a bankruptcy filing under Chapter 7 of the U.S. Bankruptcy Code. Competitive financial intermediaries offer a menu of loan sizes and interest rates wherein each loan makes zero profits. They prove the existence of a steady-state equilibrium and characterize the circumstances under which a household defaults on its loans. They show that their model accounts ...

Optimal Age-Based Vaccination and Economic Mitigation Policies for the Second Phase of the COVID-19 Pandemic
In this paper we ask how to best allocate a given time-varying supply of vaccines during the second phase of the Covid-19 pandemic across individuals of different ages. Building on the heterogeneous household model of optimal economic mitigation and redistribution developed by Glover et al. (2021), we contrast the actual vaccine deployment path that prioritized older individuals with one that first vaccinates younger workers. Vaccinating older adults first saves more lives but slows the economic recovery relative to inoculating younger adults first. Vaccines carry large welfare benefits in ...

Credit, bankruptcy, and aggregate fluctuations
We ask two questions related to how access to credit affects the nature of business cycles. First, does the standard theory of unsecured credit account for the high volatility and procyclicality of credit and the high volatility and countercyclicality of bankruptcy filings found in U.S. data? Yes, it does, but only if we explicitly model recessions as displaying countercyclical earnings risk (i.e., rather than having all households fare slightly worse than normal during recessions, we ensure that more households than normal fare very poorly). Second, does access to credit smooth aggregate ...

2013 Update on the U.S. Earnings, Income, and Wealth Distributional Facts: A View from Macroeconomics
This article is largely a description of the earnings, income, and wealth distributions in the United States in 2013 as measured by the Survey of Consumer Finances (SCF). We describe facts that lie at the joint distribution of the three variables. We look at inequality in relation to age, education, employer status, and marital status. We discuss the evolution of our results over the past 25 years (1989 - 2013), emphasizing the role played by the Great Recession. We pay special attention to the degree of income and wealth concentration at the top and discuss what the use of the SCF data can ...

A finite-life private-information theory of unsecured consumer debt
The authors present a theory of unsecured consumer debt that does not rely on utility costs of default or on enforcement mechanisms that arise in repeated-interaction settings. The theory is based on private information about a person's type and on a person's incentive to signal his type to entities other than creditors. Specifically, debtors signal their low-risk status to insurers by avoiding default in credit markets. The signal is credible because in equilibrium people who repay are more likely to be the low-risk type and so receive better insurance terms. The authors explore two ...

Intergenerational Redistribution in the Great Recession
We construct a stochastic overlapping-generations general equilibrium model in which households are subject to aggregate shocks that affect both wages and asset prices. We use a calibrated version of the model to quantify how the welfare costs of big recessions are distributed across different household age groups. The model predicts that younger cohorts fare better than older cohorts when the equilibrium decline in asset prices is large relative to the decline in wages. Asset price declines hurt the old, who rely on asset sales to finance consumption, but benefit the young, who purchase ...

Methods versus substance: measuring the effects of technology shocks on hours
In this paper, we employ both calibration and modern (Bayesian) estimation methods to assess the role of neutral and investment-specific technology shocks in generating fluctuations in hours. Using a neoclassical stochastic growth model, we show how answers are shaped by the identification strategies and not by the statistical approaches. The crucial parameter is the labor supply elasticity. Both a calibration procedure that uses modern assessments of the Frisch elasticity and the estimation procedures result in technology shocks accounting for 2% to 9% of the variation in hours worked in the ...

Intergenerational redistribution in the Great Recession
In this paper we construct a stochastic overlapping-generations general equilibrium model in which households are subject to aggregate shocks that affect both wages and asset prices. We use a calibrated version of the model to quantify how the welfare costs of severe recessions are distributed across different household age groups. The model predicts that younger cohorts fare better than older cohorts when the equilibrium decline in asset prices is large relative to the decline in wages, as observed in the data. Asset price declines hurt the old, who rely on asset sales to finance ...

Health versus Wealth: On the Distributional Effects of Controlling a Pandemic
To slow the spread of COVID-19, many countries are shutting down non-essential sectors of the economy. Older individuals have the most to gain from slowing virus diffusion. Younger workers in sectors that are shuttered have the most to lose. In this paper, we build a model in which economic activity and disease progression are jointly determined. Individuals differ by age (young and retired), by sector (basic and luxury), and by health status. Disease transmission occurs in the workplace, in consumption activities, at home, and in hospitals. We study the optimal economic mitigation policy of ...
