答案和详解如下: 36 Correct answer is B “Fiscal Policy,” Michael Parkin 2008 Modular Level I, Vol. 2, pp. 441-443 Study Session 6-27-b discuss the sources of investment finance and the influence of fiscal policy on capital markets, including the crowding-out effect The quantity of investment that firms plan to undertake depends only on how productive capital is and what it costs - its real interest rate. Therefore, a tax on interest income has no effect on investment demand. On the other hand, a tax on interest income weakens the incentive to save as savers look at the after-tax real interest rate they receive. The interest rates would rise as a result of the decrease in saving supply.
37 Correct answer is C “Demand and Supply in Factor Markets,” Michael Parkin 2008 Modular Level I, Vol. 2, pp. 271-274 Study Session 5-21-g differentiate between renewable and non-renewable natural resources and describe the supply curve for each The quantity of land and other renewable natural resources is fixed and their supply is perfectly inelastic. On the other hand, the flow supply of a nonrenewable natural resource (e.g., oil) is perfectly elastic.
38 Correct answer is C “Demand and Supply in Factor Markets,” Michael Parkin 2008 Modular Level I, Vol. 2, pp. 275-277 Study Session 5-21-h differentiate between economic rent and opportunity costs When the supply of the factor is perfectly elastic (horizontal supply curve), the factor’s entire income comprises opportunity cost. When the supply of the factor is perfectly inelastic (vertical supply curve), the factor’s entire income comprises economic rent.
39 Correct answer is B “Inflation,” Michael Parkin 2008 Modular Level I, Vol. 2, pp. 414-418 Study Session 6-26-e explain the impact of inflation on unemployment, and describe the short-run and long-run Phillips curve, including the effect of changes in the natural rate of unemployment A change in the natural rate of unemployment shifts both short-run and long-run Phillips curves. Suppose the natural rate of unemployment increases from 6 to 9%, but the inflation remains constant at 10%. As a result, both short-run and long-run Phillips curves move outward adjusting to the new, higher level of natural unemployment rate. The new point of intersection between the two lines would be at 9% unemployment rate and 10% inflation rate (Figure 11, p. 418)
40 Correct answer is B “Monetary Policy,” Michael Parkin 2008 Modular Level I, Vol. 2, pp. 473-475 Study Session 6-28-c discuss the fixed-rule and feedback-rule policies to stabilize aggregate supply in response to a productivity shock and a cost-push inflation shock According to the feedback rule, when the price level rises the Fed decreases the quantity of money in order to reduce aggregate demand. As a result, the price level as well as the real GDP would remain constant.
