I If a person walks half a mile to buy an ice-cream, and then pays price p for the ice-cream when she gets there, the total cost to the individual is 1 2 t +p I The point is, the total price a person pays to consume a product is equal to the price of the product plus some amount reﬂecting how close the product is to their ideal product. Let x < 1/n be the deviation position. This question asks you to analyze an entry-deterring strategy involving product proliferation. The flavor is called "Collin Kaepernick's Change the Whirled," a vegan non-dairy frozen dessert, which will launch in 2021. Second, consider a deviation to a position beyond one of the more extreme locations—i.e., less than 1/n or greater than (n-1)/n. 0 1 Models of Monopolistic Competition The Hotelling Model • Bathers scattered along the beach. The model is usually based on two ice-cream salesmen, A and B, on a mile of beach. Finally, consider a deviation to a position between two locations already being occupied.

This article reconsiders the Hotelling duopoly model of 1929, but under elastic demand, more precisely a linear demand function. End As we go through this lecture and the next, pay attention to how these models differ from those of Cournot and Bertrand. Customers are uniformly distributed along that interval. Formally, we can describe this as any position between (m+1)/n and (m+3)/n, for any even integer m. For example, that could be any spot between 1/n and 3/n, 3/n and 5/n, and so forth.

None are profitable, and thus this is a Nash equilibrium. Consider the following hastily made but nonetheless helpful figure: Because customers go to the closest location, the deviator takes all the customers between 0 and x as well as all customers to the left of the midpoint between x and 1/n, which is (x + 1/n)/2. Through popular information technologies (e.g., call centers, web portal, ecommerce and social media, etc. I will assume that most readers are familiar with Hotelling’s game/the median voter theorem game.

Trained in mathematics, he participated in the early twentieth century movement to mathematize economics. The vendors simultaneously select a position. And even then, as n increases, the percentage of total players occupying the median goes to 0. (This is the median voter theorem.) Yet, he’s perhaps best known for some simple yet profound observations, one of which is now known as Hotelling’s Law. Suppose that two owners of refreshment stands, George and Henry, are trying to decide where to locate along a stretch of beach. On Thursday, Ben & Jerry's announced a new ice cream flavor named after the former San Francisco 49ers quarterback.

For n = 4, two players occupy 1/4 and two players occupy 3/4. • Two ice cream vendors, charging the same price for the same product. As two competitive cousins vie for ice-cream-selling domination on one small beach, discover how game theory and the Nash Equilibrium inform these retail hot-spots. American economist Harold Hotelling is credited with the next three models, all of which deal with the spatial dimension of imperfect competition.
