This paper discusses a capacity-based redispatch mechanism in which awarded market participants are compensated for their availability for redispatch, rather than activation. The rationale is to develop a market design that prevents so-called 'inc-dec gaming' when including flexible consumers...

The spectrum for third generation (3G) mobile communications for the German market was alloted to operators by means of an auction. This resulted in a highly competitive outcome: six operators were given rights to provide 3G services. Government revenues from this auction were a staggering EUR...

We study strategic investment in continuous time with positive externalities of changing magnitude. Our model particularly allows for two correlated risk factors. Constructing subgame-perfect equilibria with pure and mixed strategies, we observe the novel effect that it is important for the...

We investigate the impact of an environmental award in a Bertrand duopoly with green consumers considering a three-stage game. First, the regulator designs the environmental contest. Second, firms choose their green investments, and the winner of the contest is awarded. Third, firms compete in...

We demonstrate how suppliers can take strategic speculative positions in derivatives markets to soften competition in the spot market. In our game, suppliers first choose a portfolio of call options and then compete with supply functions. In equilibrium firms sell forward contracts and buy call...

Anderson, Goeree and Ramer (1997) observe that although the Uniform consumer density is almost universally assumed in Hotelling style location games, it is more realistic to assume non-uniform distributions. Using Anderson et al.'s (1997) sufficient conditions for the existence of a unique pure...

We present a model where firms engage in imperfect price competition, firms cannot sell to all consumers. A bipartite network structure models the local interaction of firms and consumers. We solve for the unique equilibrium of duopolistic price competition and study the implications of network...

This paper examines the importance of geographical differentiation in store location decisions of firms in the retail discount industry. Using a novel data set that includes the store locations and accompanying market conditions for all stores belonging to the Wal-Mart, Kmart, and Target chains,...

To analyze welfare effects of input markets changes, economists studied the relationship between the surplus measured in the input markets and the surplus in the output markets. The latest results hinge on simplifying assumptions, which are relaxed here by linking the input markets surplus...
