We reveal bargaining power between upstream manufacturers and downstream supermarkets using proprietary data on product-specific wholesale and retail prices of the two largest supermarket chains in Chile. We study two dimensions of players’ bargaining power: the share of total profits each earns,...

This paper presents a model in which anonymous charitable donations are rationalized by two human tendencies drawn from the psychology literature. The first is people’s disproportionate disposition to help those they agree with while the second is the dependence of peoples’ self-esteem on the...

We propose a stylised dynamic model to understand the role of social networks in the phenomenon we call \globalization." This term refers to the process by which even agents who are geographically far apart come to interact, thus overcoming what would otherwise be a fast saturation of local...

Tracing back from Charnes, Cooper and Rhodes (1978) many approaches have been proposed to extend the DEA production model to non-convex technologies. The FDH method were introduced by Deprins, Simar and Tulkens (1984) and it only assumes a free disposal assumption of the technology. This paper...

We present a dynamic model of free riding in which n infinitely lived agents choose between private consumption and contributions to a durable public good g. We characterize the set of continuous Markov equilibria in economies with reversibility, where investments can be positive or negative; and...
