We show how non-price-taking behavior by agents in partial equilibrium can be analyzed using strategic versions of Marshallian supply and demand curves. There is a Nash equilibrium of a two-good, strategic market game at a given price if and only if the strategic supply and demand curves...

We show in the context of a bilateral oligopoly where all agents are allowed to behave strategically the unexpected result that when the number of buyers becomes large the outcomes in a strategic market game do not converge to those at the Cournot equilibrium. However, convergence to Cournot...

We prove existence and uniqueness of non-autarkic equilibria in bilateral oligopoly assuming only that preferences are binormal and satisfy a weakened version of gross substitutes. We permit complete heterogeneity of preferences and our analysis exploits the fact that payoffs depend only on own...

This paper analyses strategic trade within pure exchange economies. In the tradition of the ‘Shapley-Shubik’ case, the signals agents send to the markets are aggregated into market prices, proceeding which net trades are determined via a distribution mechanism dependent on both individual...

We exploit the aggregative structure of the public good model to provide a simple analysis of the voluntary contribution game. In contrast to the best response function approach, ours avoids the proliferation of dimensions as the number of players is increased, and can readily analyse games...
