Given input prices, what is the cheapest way to attain a certain output? Hotelling’s linear city model was developed by Harold Hotelling in his article “Stability in Competition”, in 1929.

As a result, we fo-cus on the case of a sequential play with Firm 2 being the second mover and we assume Firm 1’s location is ex-ogenous. There must be some cost to traveling because customers prefer the closest vendor. In this paper we consider a Hotelling model on the linear city, where the location is not a free good. Problem 1. In these notes we address the flrm’s problem. He used a simple model in which consumers are evenly dispersed along a line and buy from the nearest firm. Firms have an option to advertise, which is costly. (12 points) Consider a variation of the linear city model of Hotelling. Buyers are uniformly distributed in a line of length one, where L is the left end and R the right end.

It is shown that two different types of equilibria emerge: centrally agglomerated equilibria… I analyze oligopolistic competition among three or more firms located on Hotelling's (1929) Main Srreet and show that in contrast with Hotelling's duopoly, the symmetric locational structure supports a noncooperative equilibrium in prices. Firms sell a homogeneous product at a fixed price, customers distributed along the interval buy one unit each from the firm nearest to them and firms aim to maximize the number of Considering locational equilibria we show that neither holds the Principle of Maximum Di¤erentiation as in the duopoly model nor does the Principle of Minimum Di¤erentiation as in the multiple ...rms game with linear transport cost.
