We characterize optimal strategies in a simple herding model where observations have a small cost. We assume that there are two states and two possible signals that each agent may get. The prior distribution is biased towards adopting behavior. That is, ex-ante, adopting gives a higher expected...

We apply the von Neumann-Morgenstern stable set to the n-player cake division problem. Only time-preferences á la Rubinstein (1982) are assumed. The stable set is defined with respect to the following dominance relation: x dominates y if there is a player who prefers x over y even with one...

I determine the steady state equilibrium in a random matching model with a finite number of buyers and sellers. Two trading mechanisms, namely, auctions and posted prices are compared. Auctions depict a situation where the sellers are unable to commit to a reserve price, whereas posted prices...

This paper studies how comparing can be used to provide information in financial markets in the presence of a hidden characteristics problem. Although an investor cannot precisely estimate the future returns of an entrepreneur’s projects, the investor can mitigate the asymmetric information...

Constitution is a pair of rules  <formula format="inline"> <simplemath>(s, S) </simplemath> </formula> that are used in a voting situation. The rule s is used to vote about the existing alternatives and the rule S is used to vote about changing the rule s to some other rule  <formula format="inline"> <simplemath>s′ </simplemath> </formula>. We consider what kind of constitutions are likely...

In this paper we study the number of pure strategy Nash equilibria in large finite n-player games. A distinguishing feature of our study is that we allow general - potentially multivalued - best reply correspondences. Given the number K of pure strategies to each player, we assign to each player...

We consider a large market with frictions. We are in a directed search type setting, sellers are capacity constrained, post prices, and buyers contact sellers taking into account price and probability of service. We aim to endogenize the sellers' capacities. To this end we formulate a three...
