"Der Beitrag stellt das numerische allgemeine Gleichgewichtsmodell PACE-L (Policy Analysis based on Computable Equilibrium, Labour market module) in kompakter Form vor. Dieses quantitative gesamtwirtschaftliche Modell wird am IAB zur Beurteilung von beschäftigungsrelevanten Reformvorschlägen,...

We define an algebro-topological concept of essential map and we use it to prove several results in the theory of general equilibrium and nash equilibrium refinement.

In this paper, we study a two-stage location-then-price game where consumers are distributed piecewise uniformly, each piece being referred to as an interval.Although the firms face a coordination problem, it is obvious that, for any given locations and prices, there is a unique indifferent...

In this paper, we analyze a variant of the standard Hotelling model of spatial competition where firms first choose locations along the line and then, given these locations, compete in prices.Consumers have a finite reservation price and incur a quadratic transportation cost.We show that there...

In this paper the structure of the set of equilibria for two person multicriteria games is analysed. It turns out that the classical result for the set of equilibria for bimatrix games, that it is a finite union of polytopes, is only valid for multicriteria games if one of the players only has...
