We develop an equilibrium model of industrial structure in which the organization of firms is endogenous. Differentiated consumer products can be produced either by vertically integrated firms or by pairs of specialized companies. Production of each variety of consumer good requires a unique,...

This paper develops a model with multiple market locations in which the quality of intangible assets of firms, provided by management, determines the firms. performance. Despite an ex ante symmetry of potential entrants, the equilibrium assignment of heterogeneous managerial skills to firms...

We assess the consequences for market quality and welfare of different entry regimes and exchange pricing policies in a context of limited market participation. To this end we integrate a two-period market microstructure model with an exchange competition model with entry in which exchanges...

Using data from the US automobile market, we empirically examine the link between competition and innovation. Consistent with a large literature, we use patent counts as a measure of innovation. The combination of the US market's economic importance, market dynamics, and the significant...

This paper addresses the issue of how regulatory constraints affect firm s investment choices when the firm has an option to delay investment. The RPI-x rule is compared to a profit sharing rule, which increases the x factor in case profits go beyond a given level. It is shown that a pure price...

In this article we analyse the effects of different regulatory schemes (price cap and profit sharing) on a firm s investment of endogenous size. Using a real option approach in continuous time, we show that profit sharing does not affect a firm s start-up decision relative to a pure price cap...

Regulators have long been aware of the social aspects of communication. In the past, regulated monopolists have provided Universal Service Obligations, typically funded via a system of cross-subsidies. In this paper, we first review the rationale for imposing Universal Service Obligations, based...
