We propose both a well-mixed and spatially-structured evolutionary game to analyze the competitive behavior of retail firms in duopolistic markets. Firms from two different populations (high/low efficiency) compete and the available strategies are (i) Profit or (ii) Revenue maximization. Under...

Higher-dimensional symmetric games become of more and more importance for applied micro- and macroeconomic research. Standard approaches to uniqueness of equilibria have the drawback that they are restrictive or not easy to evaluate analytically. In this paper I provide some general but...

Several relaxations of Nash equilibrium are shown to exist in strategic games with discontinuous payoff functions. Those relaxations are used to extend and unify several recent results and link Reny's better-reply security condition [Reny, P.J. (1999). On the existence of Pure and Mixed Strategy...
