This paper proposes an analytic representation of perturbations in heterogeneous agent economies with aggregate shocks. Treating the underlying distribution as an explicit state variable, a single value function defined on an infinite-dimensional state space provides a fully recursive...

We propose a general simulation-based procedure for estimating quality of approximate policies in heterogeneous-agent equilibrium models, which allows to verify that such approximate solutions describe a near-rational equilibrium. Our procedure endows agents with superior knowledge of the future...

The incorporation of increasing returns and imperfect competition into applied general-equilibrium (AGE) models, beginning with Harris (1984), led to much larger welfare effects from changes such as trade liberalization. But the imperfect competition side of these IO developments has often...

We analyze the value of insurance when individuals have access to credit markets. Loans allow consumers to smooth financial shocks over time, decreasing the value of consumption smoothing from insurance. We derive formulas for the value of insurance that can be taken to data, and show how that...

Almost 50 million Americans are burdened by the need to repay almost $2 trillion in student loan debt, while at the same time having to save for retirement. This article analyzes the potential impact of the 2022 SECURE 2.0 Act reform which permits employers to match contributions for student...

The failure of the Freedman's Savings Bank (FSB), one of the only Black-serving banks in the early post-bellum South, was an economic catastrophe and one of the great episodes of racial exploitation in post-Emancipation history. It was also most Black Americans' first experience of banking. Can...

We develop a new dataset to study homeowners insurance. Our data on over 47 million observations of households' property insurance expenditures from 2014-2023 are inferred from mortgage escrow payments. First, we find a sharp 33% increase in average premiums from 2020 to 2023 (13% in real terms)...

A rent guarantee insurance (RGI) policy makes a limited number of rent payments to the landlord on behalf of an insured tenant unable to pay rent due to a negative income or health expenditure shock. We introduce RGI in a rich quantitative equilibrium model of housing insecurity and show it...

Health insurance is increasingly provided through managed competition, in which subsidies for consumers and risk adjustment for insurers are key market design instruments. We illustrate that subsidies offer two advantages over risk adjustment in markets with adverse selection. They provide...

Despite its promise to help low-wealth households manage climate risk, index insurance remains hampered by downside basis risk, meaning that an insured party suffers a loss, but receives no payment because the insurance index fails to register a loss. While efforts to reduce basis risk focus on...
