Spatial Price Equilibrium

Equilibrium Number of Firms and Economic Welfare in a Spatial Price Discrimination Model

We examine the relationship between the equilibrium number of the firms entering the market and socially efficient one. Salop (1979) investigates a mill pricing model and shows that the former is larger than the latter (excess entry theorem). We find that, in contrast to Salop (1979), the equilibrium number of the firms can be either larger or smaller than the efficient one. If the entry cost i...

Price and quantity regulation in general equilibrium

We consider a general equilibrium model with a production externality (e.g. pollution), where the regulator does not observe firm productivity shocks. We examine quantity (permit) regulation and price (tax) regulation. The quantity of permits issued by the regulator are independent of the productivity shock, since shocks are unobserved. Price regulation implies use of the regulated input is an ...

Spatial Price Discrimination with Heterogeneous Firms*

In this paper we aim to explain intuitively heterogeneous firms’ optimal location decisions in a simple spatial market. To do so, we present and solve a four-stage game of entry, location, pricing and consumption in a spatial price discrimination framework with arbitrarily many heterogeneous firms. We provide a unique equilibrium outcome without imposing restrictions on the distribution of marg...
