Current English health policy is focused on strengthening the ‘demand-side' of the health care system. Recent reforms are designed to significantly enhance the capability and status of the organisations responsible for commissioning health care services and, in so doing, to address some of the...

We consider a model with two firms operating their individual networks. Each firm can choose its price as well as its investment to build up its network. Assuming a skewed distribution of consumers, our model leads to an asymmetric market structure with one firm choosing higher investments....

Trotz schrittweiser Erfolge bei der Liberalisierung der europäischen Elektrizitätsmärkte lässt die Wettbewerbsintensität auf den Großhandelsmärkten in vielen Ländern noch zu wünschen übrig. Dementsprechend sind die Preise im Verhältnis zum wettbewerblichen Referenzmaßstab zu hoch....

Has the antitrust arsenal run out of novel theories or weapons? Think again. Recent scholarship has come to challenge conventional wisdom with the latest target of antitrust imagination being institutional investors, including diversified index funds. New economic research suggests that common...

Equilibria and optima generally differ in imperfectly competitive markets. While this is well understood theoretically, it is unclear how large the welfare distortions are in the aggregate economy. Do they matter quantitatively? To answer this question, we develop a multi-sector monopolistic...

We characterize the equilibrium and optimal resource allocations in a general equilibrium model of monopolistic competition with multiple asymmetric sectors and heterogeneous firms. We first derive general results for additively separable preferences and general productivity distributions, and...

This study provides a powerful demonstration of the real world impact of increased competition. By presenting six market case studies drawn from a variety of sectors it gives evidence of the type and magnitude of the benefits following market interventions to develop competition and free up the...
