Agricultural economists have a long history of emphasizing and analyzing the spatial dimension of agricultural and food markets. Despite a rich body of literature and important contributions to agricultural and spatial economics, one aspect is frequently disregarded: the oligopsonistic nature of...

To reduce the competition from farmers who self-produce seed, an inbred line seed producercan switch to nondurable hybrid seed. In a two-period model we investigate the impactof crop durability on self-production, pricing and switching decisions, and we examine theimpact of license fees paid by...

In a model of horizontal product differentiation, we show that local monopolied may exist under free entry when capital is perfectly mobile. In contrast both with the situation of restricted entry and with the zero-profit approach to free entry outcomens of Salop 91979), the unit profit rate of...

This Paper examines the importance of the distribution of consumers in Hotelling's circle on the comparison between the optimal and the market equilibrium levels of diversity. It finds that when most consumers are located very close to the firms, the result of Salop that the equilibrium number...

In a model of horizontal product differentiation, we show that local monopolies may exist under free entry when capital is perfectly mobile. In contrast both with the situation of restricted entry and with the zero-profit approach to free entry outcomes of Salop (1979), the unit profit rate of...

Transport costs in address models of differentiation are usually modeled as separable of the consumption commodity and with a parametric price. However, there are many sectors in an economy where such modeling is not satisfactory either because transportation is supplied under oligopolistic...

We characterize mixed-strategy equilibria when capacity constrained suppliers can charge location-based prices to different customers. We establish an equilibrium with prices that weakly increase in the costs of supplying a customer. Despite prices above costs and excess capacities, each...
