This paper studies a symmetric Bertrand duopoly with imperfect mon- itoring where rms receive noisy public signals about the state of demand. These signals have two opposite eects on the incentive to collude: avoid- ing punishment after a low-demand period increases collusive prots, mak- ing...

Dynamic competitive models of industry evolution predict higher variability of firm value over time and lower variability of firm activity over time in industries where sunk entry costs are higher. These predictions have done well empirically. Here we extend the theory to allow an additional...

In Rome, if you start digging, chances are you will nd things. We consider a famous complaint that justies the underdeveloped Roman metro system: \if we tried to build a new metro line, it would probably be stopped by archeological nds that are too valuable to destroy, so we would have wasted...

We introduce tests for finite sample multivariate linear regressions with heteroskedastic errors that have mean zero. We assume bounds on endoge- nous variables but do not make additional assumptions on errors. The tests are exact, i.e., they have guaranteed type I error probabilities. We...

Systemic risk and the scale of systemic breakdown in the banking system are the key concern for central banks charged with safeguarding overall financial stability. This paper focuses on the risk and potential impact of system-wide defaults in the frequently observed ”tiered” banking system,...

We look at a simple market with two-sided heterogeneity and pairwise meetings. On the supply side are two landlord types who differ in the quality of their apartments. On the demand side is a continuum of tentant types who differ in their valuations for apartment types and their patience. For...

Sanctions are a means to provide incentives towards more pro-social behavior. Yet their implementation can be a signal that past behavior was undesirable. We investigate experimentally the importance of the informational content of the choice to sanction. We place this in a context of a...

A distinguishing feature among households is whether adult members work or not, since the occupational status of adults affects their available time for home activities. Using a survey method in two countries, Belgium and Germany, we provide household incomes that retain the level of well-being...
