This paper studies the impact of buyer power on dynamic efficiency. We consider a bargaining model in which buyer power arises endogenously from size and may impact on a supplier's incentives to invest in lower marginal cost. We challenge the view frequently expressed in policy circles that the...

Our paper evaluates recent regulatory proposals mandating the deferral of bonus payments and claw-back clauses in the financial sector. We study a broadly applicable principal agent setting, in which the agent exerts effort for an immediately observable task (acquisition) and a task for which...

This paper provides a complete characterization of optimal contracts in principal-agent settings where the agent's action has persistent effects. We model general information environments via the stochastic process of the likelihood-ratio. The martingale property of this performance metric...

Der angekündigte mehrheitliche Verkauf des Discounters "Plus" würde der Konzentration im deutschen Einzelhandel einen neuen Schub verleihen. Die oft vorgebrachte These, dass ein Ausscheiden kleinerer Wettbewerber langfristig auch den Konsumenten schadet, ist allerdings rein spekulativ. Dieser...

This paper investigates how the formation of larger buyers affects a supplier's profits and, by doing so, his incentives to undertake non-contractible activities. We first identify two chan-nels of buyer power, which allows larger buyers to obtain discounts. We subsequently exam-ine the effects...
