2) Consider a location model of differentiated products where the set of possible products is the...
1. Two firms compete in a linear city of length 1 unit. Consumers are uniformly located along the city. Consumer i's utility derived from buying firm j's product is given by jj-(-x)2-Pj where j 1,2 indicate the two firms, t is the per unit cost of travelling along the city, is the location of consumer i, x is the location of firm j, and pj is the price of product j. Product one contains some intrinsically superior features and 22,...
Consider a consumer with income M who can buy two products, good 1 and good 2 for prices p1 and p2. If the consumer has Cobb-Douglas utility, show that her preferences are homothetic.

1. Consider the market for dried beans in a small town of 9,000 consumers. Let each consumer's preferences over beans (B, in pounds) and other goods (G) be given by U(B,G) = 120 +G For the rest of this question, fix the price of other goods at PG = 1 and let each consumer have a total weekly budget of I = 100. (a) Write the budget...
5. (30 points) Consider a Hotelling line city model, where two firms are located at the two extreme points. The length of the city is 1, and the consumers are evenly distributed over the line. Transportation cost per unit is t. The utility of the good for each consumper is 2 and each consumer only consumes one unit of good. Consumer's utility is zero without purchase. Suppose price charged by fir i 1; 2) is pi a). (10 points) Determine...
2. Consider a version of the Hotelling model in which prices are endogenously determined. Two firms sell horizontally differentiated products located at opposite ends of the one-dimensional product space. Firm O is located at 0. Firm 1 is located at 1. M consumers are uniformly distributed between 0 and 1, with each consumer's location giving his most preferred type of product. Each consumer places value v on one unit of his most preferred product, but incurs a transportation cost. AD...
1) Decreasing returns to scale may occur as increasing the amount of inputs used A) increases specialization B) may cause coordination difficulties. C) always increases the amount of output produced D) increases efficiency. 2) Which of the following statements is NOT true? A) AFC = AC - AVC C) AVC = wage/MPL B) AC = AFC + AVC D) C=F-VC 3) The more elastic the demand curve, a monopoly A) will have a larger Lemer Index. will face a lower...
Consider a market in which consumer type x is uniformly distributed on the unit interval. Consumers demand 0 or 1 unit (they buy at most one unit overall in the market). Firm A is located at 0 and firm B at 1. Firms incur constant marginal costs of production c = 1/2. There is mass 1 of consumers. A consumer located at x ∈ [0;1] obtains utility ux = r−x−pA if she buys from firm A; ux = r−(1−x)−pB if...
Consumers live uniformly in a "linear-1-mile city". There are two firms, located at r-0 and r - 1, which each produce the same physical good at marginal cost of c > 0. Consumers have transportation cost t per unit of distance. Firms are competing for customers by selecting their prices pı 2 0 and p2 2 0. It is assumed that each consumer will buy exactly one unit of the product. Firm 1 Consumer at r Firm 2 cost of...
25. A consumer is currently at point A, as shown in the figure below. With the given budget line and indifference curve to maximize utility she should: 29, A monopolist faces a downward sloping demand curve, P-4610-13. 5.Q. The maximum total revenue lbe. A) $3935.57 B) $461.0 C) $6915 D) $922.0 30. If the price in a competitive market is S30, and the demand curve is given by the equation P = 90-3Q, then the consumer surplus will be A)...

2. Consider a pure exchange economy with two goods, wine (x) and cheese (y) and two con- sumers, A and B. Let cheese be the numeraire good with price of $1. Consumer A's utility function is UA(x, y) = 2.c + y and B's utility function is UB(x, y) = xy. A's initial allocation is 10 units of c and 0 units of y. B's initial allocation is 0...
