This paper revisits the excess entry theorem in spatial models à la Vickrey (1964) and Salop (1979) while relaxing the assumption of inelastic demand. Using a demand function with a constant demand elasticity, we show that the number of firms that enter a market decreases with the degree of...

This paper explores the implications of price-dependent demand in spatial models of product differentiation. We introduce consumers with a quasi-linear utility function in the framework of the Salop (1979) model. We show that the so-called excess entry theorem relies critically on the assumption...

This paper introduces price-dependent individual demand into the circular city model of product differentiation. We show that for any finite number of firms, a unique symmetric price equilibrium exists provided that demand functions are not too convex. As in the case of unit demand, the number...

I analyze the welfare implications of protecting intellectual property rights (IPR) in developing countries through its impact on innovation, market structure, and technology transfer. FDI, tariffs, and joint ventures (JV) are introduced to the strategic IPR literature. In a North-South trade...

We analyze a drastic price increase in the German auction market for reserve power, which did not appear to be driven by increased costs. Studying the market structure and individual bidding strategies, we find evidence for collusive behavior in an environment with repeated auctions, pivotal...

The question this paper addresses is how the market structure evolves due to innovative activities when firms' level of technological competence is valuable for more than one project. The focus of the work is the analysis of the effect of learning- by-doing and organizational forgetting in R&D...
