答案和详解如下： Q1. Robert Necco and Nelson Packard are economists at Economic Research Associates. ERA asks Necco and Packard for their opinions about the effects of fiscal policy on real GDP for an economy currently experiencing a recession. Necco states that real GDP is likely to increase if both government spending and taxes are increased by the same amount. Packard states that if both government spending and taxes are increased by the same amount, there is no expected net effect on real GDP. Are the statements made by Necco and Packard CORRECT? Necco Packard
A) Incorrect Correct B) Incorrect Incorrect C) Correct Incorrect Correct answer is C) Necco is correct because the multiplier effect is stronger for government expenditures versus government taxes. All of the increase in government spending enters the economy as increased expenditure, whereas only a portion of the tax increase results in lessened expenditure (determined by the marginal propensity to consume), because part of the tax increase will come from the savings of the taxpayer (determined by the marginal propensity to save). Packard is incorrect; the effect on real GDP of an increase in government spending combined with equal increase in taxes will be positive because the multiplier effect is stronger for government spending versus the tax increase. Q2. Assuming the federal government maintains a balanced budget, the most likely effects of a tax increase on government expenditures and real GDP are: Government Expenditures Real GDP
A) Decrease Decrease B) Increase Increase C) Increase Decrease Correct answer is B) The amount of the spending program exactly offsets the amount of the tax increase, leaving the budget unaffected (balanced budget). The multiplier effect is stronger for government spending versus the tax increase. Therefore, the balanced budget multiplier will be positive. All of the government spending enters the economy as increased expenditure, whereas only a portion of the tax increase results in lessened expenditure (determined by the marginal propensity to consume), because part of the tax increase will come from the savings of the taxpayer (determined by the marginal propensity to save). Q3. Assuming the economy currently is experiencing high inflation, an example of appropriate discretionary fiscal policy is: A) reduce government expenditures on major government construction projects. B) reduce the money supply. C) increase the federal funds target rate. Correct answer is A) Discretionary fiscal policy refers to the federal government’s decisions regarding government spending and taxing. A reduction in government spending on major government construction projects is likely to lead to a reduction in aggregate demand and less pressure on prices, reducing inflation. |
