Consumer Credit Regulation and Lender Market Power Staff Working Paper 2024-36 Zachary Bethune, Joaquín Saldain, Eric R. Young 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.
