When the asset market is incomplete, there typically exist taxes on trades in assets and a redistribution of revenue in the asset market that are Pareto improving. The policy is anonymous, it economizes on complexity, and it results in ex post Pareto optimal allocations; it is publicly announced...

The introduction of banks that issue money and supply balances and pay out their profits as dividends is the natural modification of the model of general competitive equilibrium that encompasses monetary economies. Competitive equilibria exist. Nevertheless, eventhough there is a well defined...

At a Nash - Walras equilibrium, individuals exchange commodities competitively, and, simultaneously, they interact strategically. Under standard assumptions, NashWalras equilibria exist, equilibrium profiles of actions are, typically, determinate but Pareto suboptimal, though not constrained...

The competitive equilibrium correspondence, which associates equilibrium prices of commodities and assets with allocations of endowments, identifies the preferences and beliefs of individuals under uncertainty; this is the case even if the asset market is incomplete.

Individuals exchange contracts for the deliveryof commodities in competitive markets and, simultaneously, act strategically; actions affect utilities across individuals directlyor through the payoffs of contracts. This encompasses economies with asymmetric information. Nash-Walras equilibria...

The introduction of banks that issue money and supply balances and pay out their profis as dividends is the natural modification of the model of general competitive equilibrium that encompasses monetary economies with an operative transactions technology. Monetary policy sets nominal rates of...

Money provides liquidity services through a cash-in-advance constraint. The exchange of commodities and assets extends over an infinite horizon under uncertainty and complete asset market. Monetary policy sets the path of rates of interest and accommodates the demand for balances. Competitive...

The fundamentals of an exchange economy, the preferences of individuals, can be identified from the competitive equilibrium correspondence, which associates equilibrium prices of commodities to allocations of endowments; the argument extends to production economies. The essential step is the...
