Salop’s circular city model is a variant of the Hotelling’s linear city model.Developed by Steven C. Salop in his article “Monopolistic Competition with Outside Goods”, 1979, this locational model is similar to its predecessor´s, but introduces two main differences: firms are located in a circle instead of a line and consumers are allowed to choose a second commodity. 1.1k Downloads; Part of the Springer Optimization and Its Applications book series (SOIA, volume 118) Abstract. Item A is … The classical model of spatial competition (Hotelling, 1929) predicts that, when two firms (or two political parties) compete for customers (voters) by choosing locations on a linear market (policy space), the only stable outcome is for both firms to locate at the center of the market.

Abstract: This article reexamines sequential entry of firms in a Hotelling model of spatial product differentiation as analyzed by Neven (1987). Early models often assumed costless relocation, so two candidates would be expected to eventually converge to the median voter regardless of their initial positions (Hotelling, 1929; Downs, 1957; Eaton and Lipsey, 1975). This is also referred to as the principle of minimum differentiation as well as Hotelling's linear city model. Crossref.

The easiest way to view Hotelling's model as a game, is to strictly divide his model into two parts, and make a game for each: a pricing game and a location game. Not affiliated %%EOF

Econometrica. and Thisse (1991) examined a mixed market using a Hotelling-type location-then-price model with quadratic transportation costs. After the first step, in which the classical duopoly game is played, we suppose that in a second step a third firm enters the market and that the incumbents are allowed to react to this entry. In this paper we consider a Hotelling model on the linear city, where the location is not a free good. Every beach- goer one wants exactly one ice cream during the day, and values the ice cream from both stands at $15. Loertscher, S., Muehlheusser, G.: Sequential location games.
