Obstfeld and Rogoff (2000) have reinvigorated an old literature on the link between home bias in the goods markets and home bias in the asset market by arguing that trade costs in the goods market can account for the observed portfolio home bias. The key link between home bias in the two markets...

In a two-cone Heckscher-Ohlin model with CES preferences and a continuum of goods, adding new goods to the North's technology necessarily increases the Northern skill premium if the new goods are skilled-labor intensive, but may even increase the premium if they are unskilled-labor intensive....

Firms in socialist and transitional economies are often obliged to provide social goods at the same time that they are competing with private firms. This paper analyzes the impact of such bundling on the provision of private and social goods focussing on the inability of politicians to commit...

Arrow's "impossibility" and similar classical theorems are usually proved for an unrestricted domain of preference profiles. Recent work extends Arrow's theorem to various restricted but "saturating" domains of privately oriented, continuous, (strictly) convex, and (strictly) monotone "economic...

We study manipulability of multi-valued solutions in fair allocation of homogeneous indivisible objects with monetary transfers. We show that the no-envy solution satisfies some extension of strategy-proofness to multi-valued solutions. Since no-envy implies Pareto efficiency in this literature,...

The Make-Use Model serves as a basis for most national accounting systems as the System of National Accounts (SNA) and is acknowledged as the most suitable model for interregional analysis. Two hypotheses are traditionally made featuring either industry-based technologies (IBT) or...

This article reports results from an experiment that examines whether an intrinsically worthless, "token" object serves as a medium of exchange in a laboratory implementation of Kiyotaki and Wright's search model of money. The theory admits Nash equilibria in which the token object is or is not...

This article studies the problem of composite commodity in two different frameworks. In one case, aggregation across goods is analyzed for elementary goods that satisfy an optimality condition. The unrestricted case is also examined. The notion of an approximate aggregate representation is...

Armin Günther identifiziert und positioniert das sogenannte Complementor Relationship Management (CoRM) als eigenständige Sparte des Business Relationship Managements (BRM). CoRM ist das Geschäftsbeziehungsmanagement zu Anbietern ergänzender Lei­stungen wie Zubehör,...

We model firms as competing for socially responsible consumers by linking the provision of a public good (environmentally friendly or socially responsible activities) to sales of their private goods. In many cases, too little of the public good is provided, but under certain conditions,...
