We investigate firms’ incentives to locate in the same region to gain access to a large pool of skilled labor. Firms engage in risky R&D activities and thus create stochastic product and implied labor demand. Agglomeration in a cluster is more likely in situations where the innovation step is...

This paper reconsiders a dynamic model of the telephone system developed by Artle and Averous, which for the first time introduces public goods in a dynamic framework. With a more restrictive set of assumptions, their proposition showing self-sustaining growth in the demand for telephones is...

Lecture on the first SFB/TR 15 meeting, Gummersbach, July, 18 - 20, 2004We develop a general theoretical framework of trade on a platform on which buyers and sellers interact. The platform may be owned by a single large, or many small independent or vertically integrated intermediaries. We...

We investigate the interplay between firms' R&D decisions and local labor market competition and how this influences equilibrium location choices and welfare. Firms engage in risky R&D activities that generate stochastic product and derived labor demand. We show that firms located in a cluster...

We develop a general theoretical framework of trade on a platform on which buyers and sellers interact. The platform may be owned by a single large, or many small independent or vertically integrated intermediaries. We provide a positive and normative analysis of the impact of platform ownership...

A model of consumer behavior is developed in which, owing to a nonconvexity in the transportation cost of obtaining the desired commodity bundle, consumers are attracted to marketplaces offering a larger variety of commodities. Impacts on marketeers' equilibrium locations and pricing strategies...

We develop a model of search among substitutes for the best combination of commodity variant and price, in which the structure of search costs can be manipulated by the suppliers of these variants, e.g. by joining an existing market or opening a new one. We analyse the subgame perfect equilibria...

In this paper we discuss determinants of firm survival and growth in Germany within its pre-1989 boundaries. We argue that the legal form adopted by a firm is an important indicator of the riskiness of projects undertaken, and that firms under limited liability should be characterized by higher...

We develop a model of search among substitutes for the best combination of commodity variant and price, in which the structure of search costs is manipulable by the suppliers of these variants, e.g., by joining an existing market or opening a new one. We analyze the subgame-perfect equilibria...
