This note presents a simple algorithm for characterizing the set of pure strategy Nash equilibria in a broad class of entry games. The algorithm alleviates much of the computational burden associated with recently developed econometric techniques for estimating payoff functions inferred from...

We analyze the effects of market structure on the branching decisions of three types of depository institution: multimarket banks, single-market banks, and thrift institutions. We argue that additional branches increase quality for an institution's consumers, and examine the interaction between...
