Econ Exam 3
The Jones family has a disposable income of $60,000 annually. Currently, the Jones family spends 80% of new disposable income on consumption. Assume that their marginal propensity to consume is 0.8 and that their autonomous consumption spending is equal to $10,000. What is the amount of the Jones family's annual consumer spending?

Suppose that the federal administration plans to fight a deep, ongoing recession with a nationwide plan of increasing infrastructure. Congress approves it and adjusts the budget accordingly to put the plan in motion immediately. Aggregate demand spending components include consumption (C), investment (I), government (G), and exports (X) minus imports (M). Analyze what the aggregate demand and aggregate supply model predicts about the infrastructure plan to answer three questions. Does the level of G increase (+), decrease (-), or stay constant (0)? What likely happens to the aggregate demand (AD) curve? What likely happens to the level of unemployment?
+ The curve shifts to the right (an increase in AD). unemployment decreases

It increases the government purchases multiplier.
Classify each factor according to whether it is associated with a movement along the aggregate demand curve or a shift of the aggregate demand curve.
Movement along the aggregate demand curve the wealth effect the international trade effect inflation the interest rate effect deflation Shift of the aggregate demand curve a fall in government purchases a fall in taxes a fall in household expectations a fall in business expectations a fall in the growth rate of domestic GDP relative to foreign GDP a fall in the value of the domestic currency relative to foreign currencies

Household behavior with respect to changes in income can be described by the marginal propensity to consume (MPC) and the marginal propensity to save (MPS). These variables can be used to predict the eventual changes in equilibrium output after the change in income has occurred.
The greater the MPC, the larger the resulting change in output for a given change in expenditure.

Identify all of the statements that are examples of fiscal policy.
There is an increase in income tax rates. The estate tax is repealed. Government increases military spending. Public money is used to build a high-speed train that connects Los Angeles and Las Vegas.
Identify the statements about macroeconomic equilibrium as either true or false.
True When aggregate expenditure is less than GDP, inventories rise. If aggregate expenditure equals GDP, then inventories do not change. If economy‑wide spending increases, firms may increase production by hiring new workers to meet this increase in sales. False Macroeconomic equilibrium occurs when consumer spending is equal to consumer saving. Falling inventories signal that GDP is greater than aggregate expenditure.

Seven quarters ago, in time period 1 on the graph, Ruritania's economy emerged from a recession and experienced a period of growth. The economy is now heading back into recession. The Ministry of Economics is debating various fiscal policy measures, each of which has an expected lag time before becoming effective. If no action is taken, the business cycle would follow the path illustrated by the individual points on the graph. Identify which of the policies are more likely to make Ruritania's economic situation better or and which would make it worse.
Better A lengthy process of spending reforms designed to evaluate all areas of government is expected to take a year to complete. The Parliament will need another six months to approve the plan, which will result in spending cuts. A tax cut that requires three months to be approved by the Ruritanian Parliament and thereafter six months to be implemented and take effect. Worse An increase in government spending that requires nine months to be approved by the Ruritanian Parliament and thereafter one year to be implemented and take effect. A decrease in government spending coupled with an increase in taxes that require three months to be approved by the Ruritanian Parliament and thereafter three months to be implemented and take effect.
Income and Expenditure — End of Chapter Problem How will planned investment spending change as the following events occur? The interest rate falls as a result of Federal Reserve policy. The U.S. Environmental Protection Agency (EPA) decrees that corporations must upgrade or replace their machinery in order to reduce their emissions of sulfur dioxide. Baby boomers begin to retire in large numbers and reduce their savings, resulting in higher interest rates. Match each event to its effect on planned investment spending.
Increase planned investment spending Federal Reserve policy lowers interest rates. The EPA requires sulfur dioxide emissions reductions. Decrease planned investment spending Baby boomers' retirement increases interest rates.
Fiscal Policy — End of Chapter Problem The CARES Act was the largest in both nominal and real measures of fiscal relief/stimulus passed in U.S. history. The package will cost more than $2 trillion as it stabilizes consumer spending during a period of unprecedented unemployment. Simultaneously, the global pandemic caused a supply-side shock as supply chains experienced delays as households stocked up on basic necessities. In terms of AD/AS, explain if the CARES Act would cause a significant rise in the price level?
It is unlikely that there will be a significant increase in the price level, even though the SRAS curve has shifted to the left. The shift of AD to the right was small as the payments to households were used for precautionary savings.

Fabriland is currently in the midst of a deep economic recession. The country is dependent on the local textile industry, which has suffered in recent years from increased foreign competition and a mysterious livestock epidemic that wiped out 95% of Fabriland's sheep and cow population.

Answer the question. Which of the choices is the most basic rationale for the development of a government stabilization policy? Complete the sentences that address the issue of government intervention in the market to address demand shocks and supply shocks.
to reduce the severity of recessions and inflation After a demand shock, governments can use fiscal policy to return the market to its previous equilibrium. Compromise policy is often used to address supply shocks because supply shocks present conflicting difficulties: government policy makers can address either inflation or unemployment because addressing one will exacerbate the other.
