We consider a dynamic (differential) game with three players competing against each other. Each period each player can allocate his resources so as to direct his competition towards particular rivals -- we call such competition selective. The setting can be applied to a wide variety of cases:...

I study a model of oligopolistic competition in which consumers search for prices, but have no idea about the underlying price distribution. Consumers' behaviour satisfies four consistency requirements such that beliefs about the underlying distribution maximize Shannon entropy. I derive the...

In this paper we analyse a model of oligopolistic competition in which consumers search without priors. Consumers do not have prior beliefs about the distribution of prices charged by firms and thus try to use a robust search procedure: they minimise the loss relative to the searcher, who knows...
