Given a production economy, we define union games by considering strategic behavior of the suppliers of factors. We refer to the Nash equilibria of this game as union equilibria. We analyze situations where the unemployment of factors is supported as a union equilibrium. The degree of...

We associate to any pure exchange economy a game with only two players, regardless of the number of consumers. In this two-player game, each player represents a different role of the society, formed by all the individuals in the economy. Player 1 selects feasible allocations trying to make...

We consider a set of asymmetrically informed agents, where the information of each trader is susceptible of being altered when she becomes a member of a coalition. For this, we consider a general rule that depending on the coalition, a signal (or an information partition) is assigned to each...

In this paper, we consider a pure exchange economy with a finite number of agents who behave strategically on endowments. A notion of strategic equilibrium with partial disposability is defined and it is shown the existence of mixed strategies equilibria. Purification results on the strategic...

We characterize the core and the competitive allocations of a continuum economy as strong Nash equilibria of an associated game with only two players.
