Summary Hotelling’s Game. Republican candidates move to This paper reviews Hotelling's much criticized conceptualization and explores alternative theoretical explanations of the agglomeration of similar retail firms. Because Henry did not move, but stayed at the mark, he will sell to all people from 0 to 1000 feet. Anthony Downs saw that this model could explain some aspects of political competition of candidates with respect to ideological position. At the 1000-foot We study the location equilibrium in Hotelling's model of spatial competition. Hotelling’s Law can be illustrated with an example. In a beach going from west to east, of size [0,1] where consumers are distributed evenly, two identical ice cream stands (A and B) with a marginal cost of production, c > 0, try to determine their best location. Hotelling was the first to use a line segment to represent both the product that is sold and the preferences of the consumers who … than 1000 feet away from any seller buy nothing. All consumers located to the left of a would go to stand A, and all consumers located to the right of 1-b would go to stand B. Conclusion. location decisions that are economically efficient. In must "sell" to the same beach. 2000-foot mark, George will get all the customers up to the The remaining consumers, located between both stands would go to whichever is the closest. Depending on how prices are set it could lead to a Bertrand’s solution, in which the prices of both stands are equal to their marginal costs, thus achieving zero profits. google_ad_client = "pub-3998401874415199"; The key to approaching this problem is … (This is the median voter theorem.) Hotelling model analyzes the behavior of two sellers of a homogenous product who chooses price and location in a bounded one dimensional marketplace where consumers are distributed on line length l and product price is associated with transportation cost which is proportional to the distance between the consumers … However, this solution would not be an Also assume When two firms selling a homogeneous product with constant marginal cost of production are situated along a linear market, the firms will locate as close to each other as * … Harold Hoteling analyzed a model of spatial competition; i.e. Harold Hotelling was an accomplished economist. away, people do not bother to go—the vendors will no longer cluster at the middle. Introduction The principle of minimum differentiation introduced by Hotelling (1929) represents a starting point in the theory of optimal location. Hotelling's Theory defines the price at which the owner or a non-renewable resource will extract it and sell it, rather than leave it and wait. Locational interdependence refers to the impact of a business’s geographic location on its ability to operate and make a profit. Location theory 4.

And, on the other hand, there is an incentive for both stands to locate at opposite extremes in what is considered to be the strategic effect. [33], consider location models that are far removed from the Hotelling game we consider here. Yet similar cereals are viewed by consumers as good substitutes, and the standard model of this kind of situation is the Hotelling model. We will label the endpoints -1 and 1 for convenience. After google_ad_channel =""; Both lost in landslides. Equilibrium in this case will occur only Solutions for Problem Set 1 Game Theory for Strategic Advantage (15.025) Spring 2015. Introduction 2. Profits will be higher the less distance there is to the extremes, therefore maximum differentiation between stands will be given when A locates at 0 and the B at 1. These For similar reasons, Henry would move toward the center, and in equilibrium, both vendors would locate together in the middle. We assume that firms play a location-cum-price game, and that the game is played into two steps. STABILITY IN COMPETITION In his classic paper "Stability in Competition," Harold Hotelling was, as noted above, not directly concerned with retail location. b. Trained in mathematics, he participated in the early twentieth century movement to mathematize economics. So, for example, for n = 2, two players occupy the position 1/2. We can conclude by saying that in this model the key factor for product differentiation is location. the left and Democratic candidates move to the right. It also examines the extent to which the principle of minimum differentiation has stood the test of time and assesses both Hotelling's contribution to retail location theory … 1972, George McGovern won the Democratic nomination standing Hotelling’s linear city model was developed by Harold Hotelling in his article “Stability in Competition”, in 1929. Hotelling theory is named for Harold Hotelling (1895–1973). 1979: The location decision of the firm: an overview of theory and evidence. For this reason, we must assume that both ice cream stands offer the exact same ice creams, and therefore consumers’ utility will be given only by the price of the ice cream and the distance to the stand.
