Suppose that a frost in florida reduces the size of the orange crop, which causes the supply curve to shift to the left (from supply 1 to supply 2). as a result, consumer surplus a. decreases by areas b, c, d, and g. b. decreases by areas b, c, and d. c. decreases by areas b and c and increases by area g. d. decreases by areas b and c. e. none of the above. producer surplus a. increases by areas b, c, and d. b. decreases by area g. c. increases by area b and decreases by areas f and g. d. increases by areas b and c. e. none of the above.

Suppose that two firms produce differentiated products and compete in prices. as in class, the two firms are located at two ends of a line one mile apart. consumers are evenly distributed along the line. the firms have identical marginal cost, $60. firm b produces a product with value $110 to consumers. firm a (located at 0 on the unit line) produces a higher quality product with value $120 to consumers. the cost of travel are directly related to the distance a consumer travels to purchase a good. if a consumerhas to travel a mile to purchase a good, the incur a cost of $20. if they have to travel x fraction of a mile, they incur a cost of $20x. (a) write down the expressions for how much a consumer at location d would value the products sold by firms a and b, if they set prices p_{a} and p_{b} ? (b) based on your expressions in (a), how much will be demanded from each firm if prices p_{a} and p_{b} are set? (c) what are the nash equilibrium prices?
