question
If velocity and aggregate output are reasonably constant, what happens to the price level when the money supply increases from $1 trillion to $4 trillion?
answer
o The price level quadruples.
question
According to the quantity theory, changes in the:
answer
o Quantity of money lead to proportional changes in the price level.
question
Why would a central bank be concerned about persistent, long-term budget deficits?
answer
It may increase inflation expectations, making it harder to keep inflation anchored at a low, stable level.
question
If the government deficit is not financed by increased bond holdings by the public:

The monetary base and the money supply will increase.
question
What three motives for holding money did Keynes consider in his liquidity preference theory of the demand for real money balances?
answer
o Speculation motive o Precautionary motive o Transactions motive
question
In Keynes's analysis of the precautionary demand for money, what will happen to money demand if people's incomes increase?
answer
The demand for money will increase because Keynes believed that people would require more money for more transactions in the future.

question
What are the four components of planned expenditure?
answer
• Consumption expenditure, planned investment spending, government purchases, and net exports
question
How and why do changes in the real interest rate affect planned investment spending?
answer
• When the real interest rate is very low, the cost of funds is very low and the return on many of the firm's planned investments will exceed it. As the real interest rate rises, the return on fewer and fewer planned invesments will exceed the cost of funds. Thus, planned investment spending falls, as the real interest rate rises
question
If firms suddenly become more optimistic about the profitability of investment and planned investment spending rises by $100 billion, while consumers become more pessimistic and autonomous consumer spending falls by $100 billion, what happens to aggregate output?
answer
• Aggregate output remains unchanged
question
Will aggregate output rise or fall if an increase in autonomous consumer expenditure is matched by an equal increase in taxes?
answer
• Aggregate output will rise.
question
If the marginal propensity to consume is 0.8 how much would government spending have to rise to increase output by $2,000 billion?
answer
• Change in gov spending ? $400 billion
question
How much will taxes need to decrease to increase output by $2,000 billion?
answer
• Change in taxes ? $500 billion
question
If both taxes and government spending decrease by the same amount, explain whether the IS curve shifts
answer
• The IS curve shifts to the left.
question
Describe how (if at all) the IS curve, MP curve, and AD curve are affected in the following situation: There is an increase in the current inflation rate.
answer
• There is a movement along the MP curve, which increases the real interest rate, a movement along the IS curve to lower output, and a movement along the AD curve, reducing output.
question
" If f increases, then the Fed can keep output constant by reducing the real interest rate by the same amount as the increase in financial frictions." T/F
answer
• False. The Fed would need to reduce the real interest rate by a little bit less than the change in f to keep output constant.
question
Which of the following factors will affect the slope of the aggregate demand curve?
answer
• d
question
The difference between gross private domestic investment and fixed private investment represents
answer
• Inventory investment
question
The aggregate demand curve slopes downward because a rise in inflation leads:
answer
• The monetary policy authorities to raise real interest rates
question
The short-run aggregate supply curve slopes upward because an increase in output relative to potential output:
answer
• Creates tight labor and product markets that cause inflation to rise.
question
What relationship does the aggregate supply curve describe?
answer
• It describes the relationship between the total quantity of output supplied and the inflation rate.
question
The long-run aggregate supply curve is:
answer
• Vertical because changes in labor, capital ,and technology (not the inflation rate) change the output an economy can produce over the long run.
question
Which of the following would cause the long-run aggregate supply curve to shift rightward?
answer
• An increase in available technology
question
In what ways was the Volcker disinflation considered a success? What are the negative aspects of it?
answer
• The Volcker disinflation was successful in bringing inflation down with contractionary policies; however, these policies resulted in two recessions and a significant increase in unemployment.
question
What factors lead to a decrease in both the unemployment rate and the inflation rate in the 1990s?
answer
• Improved demographic factors, such as an increase in the average age of the workforce. • An increased proliferation of computer technology.
question
Which of the following best explains real business cycle theory?
answer
• The potential level of output changes due to the technology and other shocks, creating business cycles even though the economy is still producing at potential output.
question
What basic relationship does the short-run Phillips curve describe?
answer
• It describes the negative relationship between unemployment and inflation.
question
What trade-offs does this relationship seem to offer policymakers?
answer
• Policymakers can increase inflation to decrease unemployment.
question
Okun's law describes the
answer
• Negative relationship between the unemployment gap and the output gap.
question
Combining Okun's law with the Phillips curve helps derive the short-run aggregate supply curve in that:
answer
• The Phillips curve describes the short-run negative relationship between the unemployment rate and the inflation rate, while the short-run aggregate supply curve describes the positive relationship between output and inflation.
question
A "conservative" central banker:
answer
• Has a strong aversion to inflation.
question
"A decrease in short-term nominal interest rates necessarily implies a stance of monetary easing." T/F
answer
• False. Monetary policy easing should be associated with changes in real interest rates and not nominal rates.
question
If nominal interest rates are high, the exchange rate is low, and asset prices are high. Then monetary policy is best described as:
answer
• Easy.
question
Expansionary monetary policy increases stock prices and thus the net worth of firms. As net worth rises, adverse selection and moral hazard problems are reduced, and thus bank lending increases, which increases investment. This statement describes which of the following monetary transmission channels?
answer
• Balance sheet channel.
