An Anatomy of Firms’ Political Speech
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. -
Consumer Credit Regulation and Lender Market Power
We investigate the welfare consequences of consumer credit regulation in a dynamic, heterogeneous-agent model with endogenous lender market power. Lenders post credit offers and borrowers—some informed and others uninformed—apply for credit. We calibrate the model to match characteristics of the unsecured consumer credit market and use the calibrated model to evaluate interest rate ceilings. -
Housing Affordability and Parental Income Support
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.
