This paper analyzes the role of different contract types and access regulation on innovation and competition in telecommunications in the context of Next Generation Access Networks. Within a standard duopoly model, it is shown that ex-post access contracts lead less often to the duplication of...

If ownership and control are separated, leaving the manager with discretion may be of value. This paper discusses the extent to which a firm's ownership structure may serve as a commitment for shareholders not to interfere with the manager's project decisions, thereby reducing the agency cost of...

This paper introduces a model of third-degree price discrimination where a seller's pricing power is constrained by buyers' outside options. Price uniformity performs more efficiently than discriminatory pricing, as uniform pricing allows weaker buyers to exploit the more attractive outside...

We present a model of takeover where the target optimally sets its reserve price. Under relatively standard symmetry restrictions, we obtain a unique equilibrium. The probability of takeover is only a function of the number of .rms and of the insiders. share of total industry gains due to the...

This paper argues that - in contrast to an often expressed view - the formation of larger and more powerful buyers need not reduce welfare by stifling suppliers' incentives. If contracts are determined in bilateral negotiations, the presence of larger buyers may both increase suppliers'...

We provide a formal analysis of the notion that conglomerates are more ‘entrenched’ as they have ‘deeper pockets’. Using the financial contracting model of Bolton and Scharfstein (1990), we can isolate two effects that confirm this conjecture: the pooling of cash flows, which allows to...

Hat die heutige Finanzmarktkrise instabile Marktmechanismen oder mangelnde Regulierung als Ursache? Christoph Kaserer, Technische Universität München, sieht in einer Kombination aus einem Regulierungsversagen und einem ungelösten Moral-Hazard-Konflikt bei Finanzinstitutionen den Grund für...

This paper analyzes the implications of the inherent conflict between two tasks performed by direct marketing agents: prospecting for customers and advising on the product's "suitability" for the specific needs of customers. When structuring salesforce compensation, firms trade off the expected...

We characterize a monopolist's optimal offer of service plans when only informed customers know already at the contracting stage whether their demand is high or low, while uninformed customers may learn their demand only after incurring some costs, if at all. While informed customers purchase...

We challenge the view that the presence of powerful buyers stiffles suppliers' incentives to innovate. Following Katz (1987), we model buyer power as buyers' ability to substitute away from a given supplier and isolate several effects that support the opposite view, namely that the presence of...
