Question 15 Not yet answered Points out of 1.00 Flag question Put Call Parity implies that puts and calls written at the forward rate will have different values because, if the foreign interest rate exceeds the domestic rate, the forward rate is at a discount; therefore the exchange rate is expected to depreciate, making the put more valuable. Select one: O True O False Question 16 Not yet answered Points out of 1.00 Flag question A put offers the holder of an asset protection from drops in the underlying asset's value, while a call provides protection from an increase in the underlying asset's price.

Suppose that Ms. Spencer is presently spending all her budget purchasing 10 units of A and 8 units of B at prices of $2 and $4 respectively. The marginal utility of the last units of A and B are 16 and 24 respectively. These data suggest that Ms. Spencer: a) has preferences that are at odds with the principle (or law) of the diminishing marginal utility b) considers A and B to be complementary c) should buy less A and B d) should buy less B and more A 2) Marginal Utility: a) is equal to the total utility divided by the number of units consumed b) is equal to the total utility if the demand curve is linear c) increases as more of a product is consumed d) diminishes as more of a product is consumed 3) The law of diminishing returns results in: a) an eventually rising marginal product b) a total output curve that eventually increases at a decreasing rate c) an eventually falling marginal cost curve d) a total output curve that eventually rises indefinitely 4) All other things being equal, if the fixed cost of a firm increases, which of the following will happen? a) Marginal cost and average variable cost will both rise b) Average fixed cost and average variable cost will rise c) Average fixed cost and average total cost will rise d) Average fixed cost will rise, but marginal cost will fall
