This note analyzes mortgage stress tests, a macroprudential tool. We find that when mortgage stress tests are applied to all mortgage purchase originations, they improve credit quality and reduce credit and house price growth. They also improve the resilience of borrowers to financial shocks, such as the large increase in interest rates during 2022–23.

We analyze the transmission of monetary policy during different phases of a sectoral demand reallocation episode when there are frictions to increasing production in a sector. Monetary policy is more effective in reducing inflation when a larger proportion of sectors are expanding or expect to expand in the near future.

The arrival of immigrants increases demand for housing and puts upward pressure on shelter prices. Using instrumental variables based on the ancestry composition of residents in US counties, we estimate the causal impact of immigration on local shelter prices.

We study the distribution of political speech across U.S. firms. We develop a measure of political engagement based on firms’ communications (earning calls, regulatory filings, and social media) by training a large language model to identify statements that contain political opinions. Using these data, we document five facts about firms’ political engagement.

In many countries, the cost of housing has greatly outpaced income growth, leading to a housing affordability crisis. Leveraging Canadian loan-level data and quasi-experimental variation in payment-to-income constraints, we document an increasing reliance of first-time homebuyers on financial help from their parents, through mortgage co-signing. We show that parental support can effectively relax borrowing constraints—potentially to riskier borrowers.

We study a government policy that restricts repayment choices with the aim of reducing credit card debt and estimate its effects by applying a difference-in-differences methodology to comprehensive credit-reporting data about Canadian consumers. We find the policy has trade-offs: reducing revolving debt comes at a cost of reducing credit access, and potentially increasing delinquency.

I analyze the relationship between carrying a credit card balance and future financial stress. I find that carrying a balance significantly increases the likelihood that credit card holders miss future debt payments. This likelihood tends to rise as credit card balances grow and are held for long periods.

This paper describes the ecology of automated market makers, which are the most popular decentralized exchange model for the pricing and trading of crypto assets within decentralized finance.

We assess how much the recent rate-hike cycle has and will affect mortgage borrowers' consumption through its impacts on mortgage payments. Our analysis provides insights into the effects of changes in monetary policy on the consumption of mortgage borrowers.

We estimate a model of households in Norway with bequest motives, health-dependent utility, and uncertain longevity and health. Our estimates imply strong bequest motives for households both with and without offspring. We interpret this as suggestive evidence that utility from residual wealth represents forces beyond an altruistic bequest motive.
