We consider the effect of an increase in the risk from pollution. We show that in the case of a flow pollution, when the number of players is sufficiently large, the result of Bramoulle and Treich, showing that a marginal increase of risk in the neighborhood of a risk-free world is...

We consider a two-player advertising race subject to momentum. Momentum is modelled as a complementarity between current and past campaign spending in a way that is reminiscent of models of addiction and habit formation: the more effective a player's past spending has been, the more effective...

We obtain optimal emission levels and abatement expenditures in a finite-horizon transboundary pollution game with emission trading between two regions.We show that emission trading has significant impact on the optimal strategies and profits of the two regions. We find that cooperation between...

In this paper, we investigate the profitability of horizontal mergers of firms with price adjustments. We take a differential game approach and both the open-loop as well as the closed-loop equlibria are considered. We show that the merger incentive is determined by how fast the price adapts to...

Financial markets and macroeconomic environments are often characterized by positive externalities. In these environments, transparency may reduce expected welfare from an ex-ante point of view: public announcements serve as a focal point for higher-order beliefs and affect agents' behaviour...

This paper presents a strategic model of risk-taking behavior in the framework of a continuous time contest. Formally, we analyze a dynamic game in which each player decides when to stop a privately observed Brownian Motion with drift. Only the player who stops his process at the highest value...

This paper studies information acquisition and use in network games. The network structure incorporates both strategic complements (positive links) and substitutes (negative links). An information-use game played on a correlation-adjusted network is derived. Equilibrium inefficiencies in both...

Der vorliegende Diskussionsbeitrag entstand im Rahmen eines Forschungsprojektes über die monetäre Integration von fünf mittel- und osteuropäischen EU-Beitrittskandidaten (Polen, Tschechische Republik, Ungarn, Slowenien und Estland). Das hier vorgestellte Kapitel geht auf die...
