2.- Assume that consumers are uniformly distributed along a one-mile stretch of a beach. N ice cream vendors are pondering where to position their carts. The price that they are allowed to charge is fixed by the EACAC (Equal Access to Coolness for All Coalition). (Also, each consumer will buy exactly one ice cream.) Consumers incur some transportation cost of t dollars per mile when they move along the beach. (a) Show that there is no equilibrium (in locations) if N=3. That each, for each triple of positions, show that at least one firm will prefer moving to a different location. (b) Suppose N=5 and vendors position their cart each at one of the (mile) points � 1 /6 , 2/ 6 , 3 /6 , 4 /6 , 5/ 6 �. Is that an equilibrium?

In a 1000 feet length of the beach, there are 1,000 consumers uniformly distributed. Two ice-cream shops want to enter this beach and sell ice-cream with a price p =100. All consumers demand one ice-cream at the nearest shop, and a consumer who is located t feet away from the shop obtains utility u = 1100 - p - t. Assume that ice-cream shops can produce and sell without any cost. a. Suppose two ice-cream shops can choose their locations...

Two independent ice cream vendors own stands at either end of a 2 mile long beach. Everyday there are 200 beach-goers who come to the beach and distribute themselves uniformly along the water. Every beach-goer one wants exactly one ice cream during the day, and values the ice cream from both stands at $5. All of the beach-goers would rather be sunbathing or in the water, so they have a disutility to walking on the beach of $1 per mile....

Assume that voters are uniformly distributed along a straight line from “far right” to “far left” (however you want to describe each). We have seen that Hoteling’s model predicts that candidates in a two-party system will be positioned in the center. Moreover this would imply policies coming out of a two-party system will be somewhere in the middle. What happens if a viable third party / third candidate is inserted into the mix? What is the equilibrium then? (Assume that...

Along a stretch of beach are 500 children of 100 each (Labeled in clusters A,B,C,D,E, in that order.) Two ice-cream vendors are deciding simultaneously where to locate. They must choose the exact location of one of the clusters. If there is a vendor in a cluster, all 100 children will buy an ice-cream. For clusters without a vendor, 50 out of the 100 children are willing to walk to a vendor one cluster away, only 20 are willing to walk...

Assume that the speeds of cars travelling on a stretch of highway are normally distributed. A sample of 25 cars on this highway found a mean speed of 70 mph with a standard deviation of 6 mph. Construct a 95% confidence interval for the true mean speed of all cars travelling on this stretch of highway. (need check the assumptions) What is the margin of error in (1). Interpret the 95% confidence interval in the context of the problem.

Consider a continuum of consumers distributed along a line of length 100. Each consumer buys one unit of the good. There are two firms, one located at each end of the line. For simplicity, assume that firm A is located at 0 while firm B is located at 100. Firm A’s mill price is pA and firm B’s mill price is pB. A consumer located at x buying from firm A pays a full price of: pA +  . A consumer...
