c) Để sản lượng cân bằng của nền kinh tế quay về mức ban đầu là 200.000 tỷ đồng chính phủ phải tăng hay giảm thuế, mức tăng ( hay giảm) thuế là bao nhiêu ?

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?

Suppose a mutual fund qualifies as having moderate risk if the standard deviation of its monthly rate of return is less than 3%. a mutual-fund rating agency randomly selects 27 months and determines the rate of return for a certain fund. the standard deviation of the rate of return is computed to be 2.19%. is there sufficient evidence to conclude that the fund has moderate risk at the alpha equals 0.05 level of significance? a normal probability plot indicates that the monthly rates of return are normally distributed.
