The U.S. mortgage crisis that began in 2007 generated questions about the role played by Fannie Mae and Freddie Mac, the Government-Sponsored Enterprises (GSEs), in its causes. Some have claimed that the Affordable Housing Goals (AHGs), introduced by Congress through the GSE Act of 1992, and the...

We study short-term and medium-term changes in bank risk-taking as a result of supervision, and the associated real effects. For identification, we exploit the European Central Bank's asset-quality review (AQR) in conjunction with security and credit registers. After the AQR announcement,...

We study the pricing of deposit accounts following a regulation that capped debit card interchange fees in the United States and provide the first empirical investigation of the link between interchange fees and granular deposit account prices. This link is broadly predicted by the theoretical...

We study the unintended consequences of consumer financial regulations, focusing on the CARD Act, which restricts consumer credit card issuers' ability to raise interest rates. We estimate the competitive responsiveness-the degree to which a credit card issuer changes offered interest rates in...

The Durbin Amendment to the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 alters the competitive structure of the debit card payment processing industry and caps debit card interchange fees for banks with over $10 billion in assets. Market participants predicted that debit...

We show that as nonbanks' market share increases in a local residential mortgage market, the quality of mortgage services in the market improves. Two instrumental variable analyses exploiting (1) stress tests conducted by the Federal Reserve, and (2) mortgage industry surety bonds required by...

The U.S. federal government enacted fuel efficiency standards for medium and heavy trucks for the first time in September 2011. Rationales for using this policy tool typically depend upon frictions existing in the marketplace or consumers being myopic, such that vehicle purchasers undervalue the...

Price-setting models with monopolistic competition and costs of changing prices exhibit coordination failure: in response to a monetary policy shock, individual agents lack incentives to change prices even when it would be Pareto-improving if all agents did so. The potential welfare gains are in...

We study the welfare impacts of mergers in markets where some firms are already vertically integrated. Our model features logit Bertrand competition downstream and Nash Bargaining upstream. We numerically simulate four merger types: vertical mergers between an unintegrated retailer and an...
