A multiperiod exchange economy with gold used both as money and as jewelry is examined in this paper. The existence of Nash equilibria is proved for the market games with finitely many traders as well as the games with a continuum of traders. For market games with a continuum of traders at...

Several models of exchange are presented here to illustrate various conceptual problems in the microeconomic model of the velocity of money and the meaning of and cost of liquidity in an exchange economy without exogenous uncertainty.

In particular in some structures a role for government or an outside bank may be called for to support an equilibrium. An example of an OLG model with production...

We propose a game-theoretic model to study various effects of scale in an insurance market. After reviewing a simple static model, we present a one-period game in which both the buyers and sellers of insurance make strategic bids, and show that, under reasonably broad conditions, market...

The role of long lived assets is considered in serving as hostages to extend the domain of trustless trade in an exchange economy. Assuming that individuals have life cycle preferences, we consider the most general set of utility functions consistent with these preferences and a stationary...
