nature of the Nash equilibrium without considering existence. We recognize that jurisdictions wish to choose efficient policy … packages (Non-malevolence Theorem) and this allows us to examine the existence of equilibrium when there are multiple policy … instruments. Sufficient conditions for existence are established followed by three examples. In the first, the sufficient …

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 …

In this paper we have analyzed existence, uniqueness and stability of a steady-state equilibrium in an overlapping …
