In the text-book model of dynamic Bertrand competition, competing firms meet the same demand function every period. This is not a satisfactory model of the demand side if consumers can make intertemporal substitution between periods. Each period then leaves some residual demand to future...

This paper studies whether a sequence of myopic blockings leads to a stable matching in the roommate problem. We prove that if a stable matching exists and preferences are strict, then for any unstable matching, there exists a finite sequence of successive myopic blockings leading to a stable...

We consider an extension of Tullock's (1980) N-player contest under which prize valuations may vary across players. We show that the pure-strategy equilibrium of this contest is unique. We also establish the following results: rent dissipation increases, individual winning probabilities...

We investigate an economy in which firms have different risks to go bankrupt. We observe two things: first, workers in firms with higher bankruptcy risk (bad firms) always work less than workers in good firms. Second, the CEOs of bad firms may nonetheless receive larger wages. Copyright...

We consider a multi-period auction with a seller who has a single object for sale, a large population of potential buyers, and a mediator of the trade. The seller and every buyer have independent private values of the object. The mediator designs an auction mechanism which maximizes her revenue...

An auction house runs a second-price auction with a possibility of resale through re-auctions. It collects listing and closing fees from the seller. We find the fees which maximize the revenue of the auction house. In particular, we show that the optimal listing fee is zero. Our findings are...
