- If the government increases its purchases of goods and services by $20 billion and finances this increase by raising lump-sum taxes by $20 billion, what is the most likely short-run effect on aggregate output?
Answer: Output will increase because the government spending directly adds to aggregate demand, while the tax increase reduces it by a smaller amount.
This scenario describes the balanced budget multiplier concept. The $20 billion in government spending (G) is a direct, dollar-for-dollar injection into aggregate demand. The $20 billion tax increase reduces disposable income by that amount. However, households would not have spent the entire $20 billion; they would have saved a portion of it. Therefore, consumption (C) falls by less than $20 billion (specifically, by $20B * MPC). Since the increase in G is larger than the decrease in C, the net effect is an increase in aggregate demand and output.
- The economy enters a sudden and severe recession. Policymakers take twelve months to debate, pass, and implement a fiscal stimulus package. By the time the government spending begins to circulate, the economy is already in a strong recovery phase. This scenario illustrates how fiscal policy can inadvertently be pro-cyclical due to:
Answer: recognition, legislative, and implementation lags.
This scenario is a classic example of the time lags inherent in discretionary fiscal policy. The 'recognition lag' is the time it takes to realize a recession has started, the 'legislative lag' is the time for policymakers to agree on and pass a law, and the 'implementation lag' is the time it takes for the spending to actually occur. When these lags are significant, a policy intended to be counter-cyclical (fighting a recession) can end up being pro-cyclical (overheating an already recovering economy).
- A key argument for using government spending instead of tax cuts to stimulate an economy out of a severe recession is that:
Answer: fearful households and firms might save tax cuts rather than spend or invest them.
During a severe recession characterized by low confidence (sometimes called a liquidity trap), households and firms may have a high propensity to save any extra income. If a tax cut is enacted, a large portion might be saved or used to pay down debt rather than being spent on consumption or investment. In contrast, government spending is a direct injection of demand into the economy that does not depend on the confidence or spending decisions of the private sector.
- Even when economists agree that contractionary fiscal policy is needed to combat severe inflation, it is often difficult to implement. The most significant reason for this difficulty is that:
Answer: the tools of contractionary policy, raising taxes and cutting spending, are generally politically unpopular.
This question addresses the political economy of fiscal policy. The tools of contractionary policy involve inflicting direct financial pain on constituents, either by increasing their tax burden or by cutting government programs and services they value. Elected officials are often reluctant to take such actions for fear of losing public support and being voted out of office, even if the policy is economically prudent.
- Two economies, Richland and Poorland, are in a recession. Each government provides a $1,000 payment to every citizen. In Richland, a wealthy country, most citizens save the money. In Poorland, most citizens immediately spend the money on necessities. The short-run effect of this policy on output and employment will likely be:
Answer: larger in Poorland because its citizens have a higher marginal propensity to consume.
The effectiveness of a fiscal stimulus like a cash payment depends on the marginal propensity to consume (MPC)—the fraction of extra income that households spend. Lower-income individuals (as in Poorland) tend to have a higher MPC because they need to spend additional income on necessities. Higher-income individuals (as in Richland) are more likely to save it. A higher MPC leads to a larger spending multiplier, meaning the initial government payment will circulate more through the economy, resulting in a larger overall impact on output and employment.
- Which of the following fiscal policy actions is primarily intended to increase potential output in the long run rather than manage short-run aggregate demand?
Answer: Increased government funding for universities and basic scientific research.
Potential output is determined by an economy's factors of production, such as capital, labor, and technology. Government funding for education and research aims to improve human capital and foster technological advancements. These changes increase the economy's productive capacity, shifting the long-run aggregate supply curve. The other options are examples of demand-side fiscal policy intended to address short-run fluctuations (recession or inflation).
- An economy is experiencing an inflationary gap where aggregate demand exceeds the long-run potential output. Which discretionary fiscal policy would be most appropriate to restore long-run equilibrium?
Answer: Postponing planned infrastructure projects and increasing income tax rates.
An inflationary gap requires contractionary fiscal policy to reduce aggregate demand and curb inflation. Postponing infrastructure projects is a decrease in government spending (G), and increasing income tax rates is a decrease in disposable income, which reduces consumption (C). Both actions shift the aggregate demand curve to the left. Choices A and B are examples of expansionary fiscal policy, which would worsen the inflation. Choice D is a supply-side policy aimed at long-run growth, not at managing short-run aggregate demand.
- If an economy is at full employment and the government increases spending on national defense without raising taxes, the most likely outcome in the short run is:
Answer: an increase in the price level with little or no increase in real output.
When an economy is already at full employment (operating at its potential output), there are few idle resources. An increase in government spending will shift the aggregate demand curve to the right. Because the economy is already at its productive capacity (a vertical long-run aggregate supply curve), firms cannot significantly increase real output. Instead, the excess demand will bid up wages and prices, leading primarily to inflation rather than an increase in real production.
- Assume the marginal propensity to consume (MPC) is 0.75. Which of the following fiscal policies would have the largest total impact on aggregate demand after all multiplier effects?
Answer: A $100 billion increase in government purchases of goods and services.
The government spending multiplier is 1/(1−MPC)=1/0.25=4. The tax/transfer multiplier is MPC/(1−MPC)=0.75/0.25=3.
A) Total impact = $100B∗4=$400B.
B) Total impact = $120B∗3=$360B.
C) Total impact = $120B∗3=$360B.
D) Total impact = $50B∗4)+($50B∗3)=$200B+$150B=$350B.
Therefore, the $100 billion increase in government purchases has the largest total impact. - The government announces a temporary, one-year reduction in income taxes. The resulting increase in employment and output is significantly smaller than economists had predicted. Which of the following best explains this outcome?
Answer: Consumers, anticipating that taxes will return to their normal level, saved most of the tax cut instead of spending it.
This question relates to the permanent income hypothesis or rational expectations. If people believe a tax cut is only temporary, they are unlikely to change their long-term consumption habits. Instead of increasing spending significantly, they may choose to save the extra income to pay the higher taxes they expect in the future. This leads to a much smaller impact on aggregate demand and employment than a permanent tax cut would have.
- The size of the government spending multiplier is likely to be smaller if:
Answer: a large portion of the increased income is used to purchase imported goods.
The multiplier effect relies on the initial spending becoming someone else's income, which is then re-spent within the domestic economy. If a large portion of the new income is spent on imports, that money 'leaks' out of the domestic circular flow and becomes income for foreign producers. This leakage reduces the amount of subsequent rounds of domestic spending, thereby making the overall multiplier effect smaller.
- Suppose the government increases spending by $100 billion without raising taxes. If the central bank fears this will cause inflation and acts to keep aggregate demand stable, what monetary policy action would it most likely take?
Answer: It would sell government bonds on the open market to raise interest rates.
The increase in government spending is expansionary fiscal policy, which increases aggregate demand. To counteract this and prevent inflation, the central bank would need to implement contractionary monetary policy. Selling government bonds on the open market reduces the money supply, which increases interest rates. Higher interest rates discourage investment and consumption, thus decreasing aggregate demand and offsetting the fiscal stimulus. Choices B and C are expansionary monetary policies.
- A government engages in significant deficit spending to stimulate a recessed economy. Which of the following describes the 'crowding-out' effect that could partially offset the policy's effectiveness?
Answer: Government borrowing increases the demand for loanable funds, raising interest rates and reducing private investment.
The crowding-out effect specifically refers to the mechanism where increased government borrowing to finance deficits raises the demand for loanable funds. This leads to higher real interest rates, which in turn makes it more expensive for private firms to borrow for investment projects. This reduction in private investment spending partially counteracts the increase in aggregate demand from the government's expansionary fiscal policy.
- During a national recession, the federal government passes a large stimulus package. However, many state governments, which are required by their constitutions to balance their budgets, are forced to cut spending and raise taxes. This fiscal response by state governments will:
Answer: partially counteract the federal stimulus because their actions are pro-cyclical.
Federal fiscal policy can be counter-cyclical (spending more during a recession). However, state and local governments often have balanced-budget amendments that force them to cut spending or raise taxes when their tax revenues fall during a recession. These actions are pro-cyclical—they are contractionary during a downturn—and they work against the expansionary policy of the federal government, thus partially offsetting the intended stimulus.
- During a period of rapid economic growth, national income rises. Without any new action from the legislature, government tax revenues increase and government spending on programs like unemployment insurance decreases. This situation is an example of:
Answer: automatic stabilizers working to apply a contractionary effect on the economy.
Automatic stabilizers are features of the tax and transfer system that work to temper economic fluctuations without direct legislative action. During an expansion, a progressive tax system automatically collects more revenue as incomes rise, and fewer people qualify for unemployment benefits. These two effects reduce disposable income and government outlays, respectively, which dampens aggregate demand and acts as a natural brake on the economy, thus having a contractionary effect.
- A government decides to increase spending on infrastructure by $50 billion. In a separate legislative action, it also enacts a $50 billion tax cut for households. Assuming all other factors are constant, which statement best compares the short-run impact of these two policies on aggregate demand?
Answer: The spending increase will have a larger impact because the entire amount is injected into the economy, while part of the tax cut will be saved.
An increase in government purchases (G) directly increases aggregate demand by the full amount of the spending. A tax cut, however, increases disposable income, but households will typically save a portion of this additional income (based on their marginal propensity to save). Therefore, only the portion that is spent (determined by the marginal propensity to consume) initially adds to aggregate demand. This makes the initial impact of the government spending larger than that of the tax cut of the same size.
- A government enacts a new policy providing significant tax credits to corporations for spending on research and development (R&D). The primary goal of this fiscal policy is to influence output and employment by:
Answer: shifting the long-run aggregate supply curve to the right.
This is an example of supply-side fiscal policy. By incentivizing R&D, the government aims to foster technological innovation and improve productivity. These factors increase the economy's potential output, which is represented by a rightward shift of the long-run aggregate supply (LRAS) curve. While it might have some short-run demand effects, its primary and intended purpose is to boost long-term growth capacity.
- Expansionary fiscal policy financed by government borrowing is intended to increase output and employment. However, in an open economy with flexible exchange rates, this effect can be dampened because the policy often leads to:
Answer: an increase in the domestic interest rate and an appreciation of the currency.
The multi-step reasoning is as follows: 1) Expansionary fiscal policy (deficit spending) increases the demand for loanable funds, raising domestic interest rates. 2) Higher interest rates attract foreign financial investment, increasing the demand for the country's currency. 3) This increased demand causes the currency to appreciate. 4) A stronger currency makes exports more expensive and imports cheaper, leading to a decrease in net exports, which partially counteracts the initial stimulus to aggregate demand.
- Which statement accurately distinguishes between the short-run and intended long-run effects of a fiscal policy that reduces the tax rate on capital gains?
Answer: In the short run it increases aggregate demand, and in the long run it is intended to increase aggregate supply.
In the short run, reducing the tax on capital gains increases the disposable income of those with investments, which can lead to higher consumption and investment, shifting the aggregate demand curve to the right. The intended long-run effect, however, is a supply-side goal: to incentivize saving and investment in capital, which increases the economy's productive capacity and shifts the long-run aggregate supply curve to the right.
- Suppose a country's national debt is already very high. The government now wishes to use deficit spending to combat a recession. This fiscal policy action may be less effective at increasing employment because:
Answer: households and firms may fear future tax hikes or spending cuts, leading to more saving.
This concept is related to Ricardian equivalence. When the national debt is already high, further deficit spending can increase concerns among the public and in financial markets about future fiscal solvency. Households might anticipate that large future tax increases or spending cuts will be necessary to pay off the debt. In response, they may increase their precautionary savings and reduce current consumption, which dampens or even negates the intended stimulative effect of the deficit spending.
