We examine the effect of railway travel on urban spatial structure in a polycentric urban land use model. We focus on the role of access to the railway network. We find that if the number of train stations is limited, the degree of urbanization is higher around train stations, but the effect of...

This paper analyzes the impact of corporate taxes on structural unemployment, using an applied general equilibrium model for the European Union. We find that the unemployment and welfare effects of corporate taxes differ considerably among European countries. The magnitude of these effects rise...

The paper presents a polycentric general equilibrium model with congestion externalities and distortionary labor taxation calibrated to fit the key empirical regularities of the regional economy and transport system of Randstad conglomeration. In line with more stylized models, marginal external...

This contribution deals with the fundamental critique in Dinar et al. (1992, Theory and Decision 32) on the use of Game theory in water management: People are reluctant to monetary transfers unrelated to water prices and game theoretic solutions impose a computational burden. For the bilateral...

We study the existence problem of a zero point of a function defined on a finite set of elements of the integer lattice of the n-dimensional Euclidean space. It is assumed that the set is integrally convex, which implies that the convex hull of the set can be subdivided in simplices such that...

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...

This paper examines how a radical technological innovation affects alliance formation of firms and subsequent network structures. We use longitudinal data of interfirm R&D collaborations in the biopharmaceutical industry in which a new technological regime is established. Our findings suggest...

One of the most powerful internet communication channels is email. As employees and their clients communicate primarily via email, much crucial business data is conveyed via email content. Where businesses are understandably concerned, they need a sophisticated workflow management system to...

This paper studies mergers in markets where firms invest in a portfolio of research projects of different profitability and social value. The portfolio nature of the investment problem brings about novel insights on the external effects of firms' investments. The investment of a firm in one...

Are differences in inventor productivity due to differences in inventors’ skills or differences in the capabilities of the firms they work for? We analyze a 37-year panel that tracks the patenting of U.S. inventors and find strong evidence for serial correlation in inventors’ productivity....
