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. Regarding the statements made by Necco and Packard: Necco Packard（）①A. Correct Correct ②B. Correct Incorrect ③C. Incorrect Incorrect
A. ①
B. ②
C. ③
参考答案：B
解析：
Necco is correct because the multiplier effect is stronger for government expenditures versus government taxes. M1 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.
