Migration plays a key role in city finances with every new entrant reducing debt per person and every exit increasing it. We study the interactions between regional borrowing, migration, and default from empirical, theoretical, and quantitative perspectives. Empirically, we document that...

Taste shocks result in nondegenerate choice probabilities, smooth policy functions, continuous demand correspondences, and reduced computational errors. They also cause significant computational cost when the number of choices is large. However, I show that, in many economic models, a...

We study the implications of incarceration for the earnings and employment of different groups, characterized by their race, gender, and education. Our hidden Markov model distinguishes between first-time and repeat incarceration, along with other persistent and transitory nonemployment and...

The authors forecast the effects of the COVID-19 pandemic on loan delinquency rates under three scenarios for unemployment and house price movements. In the baseline scenario, their model predicts that loan delinquency rises from 2.3 percent in 2019 to a peak of 3.9 percent in 2025 with a total...

The standard approach to discretizing VARs uses tensor grids. However, when the VAR components exhibit significant unconditional correlations or when there are more than a few variables, this approach creates large inefficiencies because some discretized states will be visited with only...

ow do credit default swaps (CDS) affect sovereign debt markets? The answer depends crucially on trading frictions, risk-sharing, arbitrage violations, and spillovers from secondary to primary markets. We propose a sovereign default model where investors trade bonds and CDS over the counter via...
