International Workshop
General Equilibrium and Strategic Interactions:
Theories and Applications

Recent developments in general equilibrium theory focus on strategic interactions. Several models offer strategic foundations for the theory of perfect competition. Others analyze the functioning of markets and the working of market power in economies where competition takes place on multiple markets among many agents. This workshop is devoted to recent developments in the field.
