We use a model with agency frictions to analyze the structure of a dealer market that faces competition from a crossing network. Traders are privately informed about their types (e.g. their portfolios), which is something the dealer must take into account when engaging his counterparties....

Internationally, there is no consensus concerning the legal and moral judgment of prostitution. Nevertheless, there is an overwhelming agreement on the need to fight sexual slavery. We analyze how a law - introduced to punish clients of commercial sex services - affects market outcomes. More...

We examine the design of nonlinear prices by a multiproduct monopolist who serves customers with multidimensional but correlated types. We show that the monopoly can exploit the correlations between consumers' types to design pricing mechanisms that fully extract the surplus from each consumer....

We study a dynamic model of monopolistic provision of commitment devices to sophisticated, Strotzian decision makers. We allow for unobservable heterogeneity at the contracting stage in the agents' preferences for commitment vs. flexibility. The first-best contracts under complete information...

We analyze vertical structures where a regulated network operator serves n network users, and the network users compete in quantities for customers. We distinguish two cases: (i) none of the network users are related to the network operator (ownership unbundling), (ii) one of the network users...

We introduce pollution, as a by-product of production, into a non-tournament model of R&Dwith spillovers. Technology policy takes the form of either R&D subsidisation or pre-competitiveR&D cooperation. We show that, when the emissions tax is exogenous, the optimal R&Dsubsidy can be negative,...

We analyze social learning and innovation in an overlapping generations model in which available technologies have correlated payoffs. Each generation experiments within a set of policies whose payoffs are initially unknown and drawn from the path of a Brownian motion with drift. Marginal...

Die Frage nach der Kausalität fällt in die Methodologie. Methodologie ist in denWirtschaftswissenschaften ein Bereich, der sowohl bei Ökonomen als auch bei Philosophenkaum Beachtung findet. ....

This paper contributes to the literature by introducing the nexus between financial constraints and thecapital-labour uptake and by considering the capital-labour ratio to overcome the problems that haveplagued investment literature -regarding the investment-cash flow sensitivity of constrained...

This paper investigates the influence of a firm's financial status on the within-firm allocation of funds, reected in its plant-level investment and exit decisions.
