In monetary models in which agents are subject to trading shocks there is typically an ex-post inefficiency in that some agents are holding idle balances while others are cash constrained. This inefficiency creates a role for financial intermediaries, such as banks, who accept nominal deposits...

The paper presents a model of a software monopolist who benefits from a lagged network externality arising from consumers' feedback through the so-called bug-fixing effect. That is, the software producer is able to correct errors in the software code detected by previous users, improving her...

In a standard general equilibrium model it is assumed that there are no price restictionsand that prices adjust infinitely fast to their equilibrium values. In this paper the set ofadmissible prices is allowed to be an arbitrary convex set. For such an arbitrary set it cannotbe guaranteed that...

Diese Arbeit beschäftigt sich mit der Integration unfreiwilliger Arbeitslosigkeit in allgemeine Gleichgewichtsmodelle offener Volkswirtschaften. Das Walras oder Arrow-Debreu allgemeine Gleichgewichtskonzept wird im Licht unfreiwilliger Arbeitslosigkeit neu bewertet, und mit dem allgemeinen...
