We analyse the impact of market structure on the probability of banking failure when banks’ loan portfolios are subject to aggregate uncertainty. In our model borrowers are subject to a moral hazard problem, which induces banks to choose between two second-best alternative devices: costly...

Why do some workers sign contracts with high quitting penalties? Are these restrictions on the workers' mobility perverse for efficiency or workers' welfare? We postulate an answer that hinges on the degree of observability of the worker's performance by alternative employers. When performance...

We study how market power affects investment and welfare when banks choose between restricting loan sizes and monitoring, in order to alleviate an underlying moral hazard problem. The impact of market power on aggregate welfare is the result of two countervailing effects. An increase in banks'...

We develop a model of banking competition which allows us to disentangle the roles that limited liability, deposit insurance (both with flat and risk-based premia), and rivalry for deposits play in determining risk-taking incentives both in the asset and the liability side of the balance sheet....

Many economists and policy analysts seem to believe that loyalty-rewarding pricing schemes, like frequent flyer programs, tend to reinforce firms' market power and hence are detrimental to consumer welfare. The existing academic literature has supported this view to some extent. In contrast, we...
