答案和详解如下：
Question 36 The correct answer was C) An increase in nominal GDP will cause a shift in the money demand curve to the right. This is a result of inflation
and/or increased output. This question tested from Session 6, Reading 25, LOS a, (Part 1)
Question 37 The correct answer was A) a decrease in aggregate demand because the government purchases multiplier is greater than the tax multiplier. Since the government purchases multiplier is greater than the tax multiplier, a decrease in government spending will decrease aggregate demand more than an equal-sized tax reduction will increase aggregate demand. This question tested from Session 6, Reading 27, LOS d
Question 38 The correct answer was C) The extra revenue that product innovation produces must be weighted against its costs. A firm is considered to be spending the optimal amount on innovation when the marginal cost of additional innovation just equals the marginal revenue from additional innovation. This question tested from Session 5, Reading 20, LOS c
Question 39 The correct answer was C)
The percentage change in quantity demanded is (20 – 15) / [(20 + 15) / 2] = 28.57% and the percentage change in price is (2.46 - 2.90) / [(2.90 + 2.46) / 2] = -16.42%. Thus, price elasticity = 28.57% / -16.42% = -1.74. This question tested from Session 4, Reading 13, LOS a, (Part 1)
Question 40 The correct answer was C) If a monopolist produces the quantity of output for which marginal cost equals marginal revenue, it will earn an economic profit. Monopolists expand output until marginal revenue equals marginal cost. However, to realize an economic profit, the demand curve must lie above the firm’s average total cost curve at that quantity. This question tested from Session 5, Reading 19, LOS b
