In the Hotelling model, customers' preferences are located by points on the same line segment. (1979) showed that, because a key calculation in Hotelling’s model is incorrect, the minimum differentiation equilibrium does not exist. Put every voter on a line, from right to left; candidates move towards the center. I will not give you more practice problems later on. Hotelling (1929) claimed that competition in differentiated products results in minimal differenti- ation. D’Aspremont et al. Our model thus features more than two oligopolistic competitors on the Hotelling line. Their location on this interval is their taste x. First, businesses tend to locate near rivals, despite price pressures. Lane's model represents brands in two-dimensional Topic: Hotelling’s model and product differentiation VERY IMPORTANT : do not look at the answers until you have made a VERY serious effort to solve the problem. Second, because of product differentiation, price changes do not necessarily cause a dramatic movement of consumers from one firm to another. If you turn to the answers to get clues or help, you are wasting a chance to test how well you are prepared for the exams. The same line is used to represent products. Linear and quadratic forms of transportation cost have been widely used in spatial competition models [1,2]. yxop Hotelling was the first to use a line segment to represent both the product that is sold and the preferences of the consumers who are buying the products. Keywords: Hotelling’s Model; Transportation Cost; Product Differentiation . Minimum differentiation is obtained when the transportation cost is linear in travel distance. Horizontal Di erentiation: Hotelling model Each version of the good attached to an "address" in space of pos-sible con gurations. (Harold Hotelling’s simple model of product differentiation dates to 1929. Introduction . Firm 1 and Firm 2 (price setters firms) located at 0 and kilometre 10 respectively. The politics version is the median voter theory.) With a little bit of detail added, this model, due to Hotelling, helps clarify the strategic nature of our electoral game. Choosing two firms, as most of the theoretical literature which models differentiation à la Hotelling, has substantial analytical advantages due to the implied complete symmetry of the firms. Like Hotelling's model, each consumer has an ideal product in this dimension at constant prices. 1. Consumers (each with unit demand) are distributed uniformly along a straight line from 0 mile and end at 10 mile. Horizontal Product Differentiation: Hotelling Model. Hotelling’s linear city not well tted to analyze this question because of boundary e ects. Each consumer’s utility depends on quantity ... many products in equilibrium ?

The product equilibrium consists of min- imum differentiation at equal prices and maximal differentiation when both prices and product positions are considered. This paper applies an unconstrained Hotelling linear city model to study the effects of managerial delegation on the firms’ location/product differentiation level in a duopoly industry. Product similarity (e.g., the degree to which Burger King and McDonald‘s menus are similar) Political ideology (e.g., the tendency for Republicans and Democrats to move towards the political centre) 29/10/2018 Hotelling's Model 13 Consider a spatial (Hotelling) model of product differentiation. A customer with taste x who pays p for the product from the firm located at y gets a utility of 40 2|x y] p, and there is always an option of not buying a product at all, which gives a utility of O. Proposing a similar utility function Despite shortcomings of the original model, Hotelling’s key insights endure. There is a customer at each point of the segment on the interval [0,20].
