we are able to obtain a necessary and sufficient condition for existence that requires an equilibrium price vector to … satisfy finitely many inequalities. A necessary and sufficient condition for the existence of market equilibrium when the …

This paper establishes the existence of a stationary equilibrium and a procedure to compute solutions to a class of …

large class of private value auctions, ties never occur in the equilibrium of the augmented game. This establishes existence …

We show existence of equilibria in istributional strategies for a wide class of private value auctions, including the … first general existence result for double auctions. The set of quilibria is invariant to the tie-breaking rule. The model … involves a positive volume of trade. The existence proof establishes new connections among existence techniques for …

the existence of optimal contracts. We also show that the first-order approach is valid in generalized agency problems if …

for the existence of market equilibrium. We assume that the production functions of the profit maximizing agents are …

In the standard CAPM with a riskless asset we prove existence of equilibria without assuming concavity of the investor …

existence of the short-run equilibrium and the long-run equilibrium in a two-sector growth model with an intermediate product …

This paper proposes conditions for the existence and uniqueness of solutions to systems of linear differential or …
