Which of the following represents a movement along a given AD curve? A. Inflation increases, the real interest rate increases, and aggregate output increases. B. Inflation increases, the real interest rate decreases, and aggregate output increases. C. Inflation decreases, the real interest rate decreases, and aggregate output decreases. .D. Inflation decreases, the real interest rate decreases, and aggregate output increases.
D
What is the aggregate demand curve?
It is the relationship between the inflation rate and aggregate output when the goods market is in equilibrium.
Which of the following causes the MP curve to shift down?
an autonomous easing of monetary policy
If the Fed continued a movement up along the MP curve as inflation rose, its actions would be described as ________
automatic
If lambdaλ = 0, what does that imply about the relationship between the nominal interest rate and the inflation rate? When lambdaλ = 0, this means that as inflation increases, the nominal interest rate will _______ by _______ the inflation rate, so that the real interest rate _______
increase, exactly the same as, stays constant
mp curve
r+lamda(pie)
Why does the aggregate demand curve slope downward?
A rise in inflation works through the increase in real interest rates to reduce the equilibrium quantity of aggregate output.
Why is it necessary for the MP curve to have an upward slope?
An upward-sloping MP curve keeps inflation from spinning out of control.
What is the key assumption underlying the Fed's ability to control the real interest rate?
Because inflation is relatively sticky in the short run, when the Federal Reserve changes the federal funds rate, it implies similar changes in real interest rates.
Given that a steep downturn ensued following the financial crisis despite the Fed's autonomous easing, it may be concluded that the A. Fed acted too late to stem the downturn. B. negative shock to the economy was overwhelmingly severe. C. Fed was insufficiently aggressive. D. all of the above are plausible conclusions.
D
When r overbarr decreasesdecreases, this causes a movement along the________ curve, and shifts the _________ curve.
IS;AD
Why can the Fed control the real interest rate in the short run but not in the long run?
It adjusts for inflation, and prices are sticky in the short run. Hence, when a change in the Fed's monetary policy causes the nominal interest rate to change, the real interest rate also changes in the same direction. In the long run, actual and expected inflation change in response to changes in monetary policy, leaving the real interest rate unaffected.
What is the monetary policy curve?
It indicates the relationship between the inflation rate and the real interest rate.
Why does the monetary policy curve slope upward?
Monetary policymakers will follow the Taylor principle and respond aggressively to an increase in the inflation rate by raising nominal interest rates by an even greater amount so that the real interest rate also rises. When inflation increases, the supply of real money balances declines. This increases the equilibrium nominal interest rate in the money market, which also increases the real interest rate in the short run
Would aa decreasedecrease in net exports affect the monetary policy curve?
No, the monetary policy curve does not shift.
Allowing the real interest rate to rise as inflation rises is said to be driven by the
Taylor principal
Describe how (if at all) the IS curve, MP curve, and AD curve are affected in the following situation: There is an increase in taxes comma and an autonomous easing of monetary policy.There is an increase in taxes, and an autonomous easing of monetary policy.
The IS curve shifts to the left and the economy moves along the IS curve, the MP curve shifts down, and the net effect on the AD curve cannot be definitely determined.effect on the AD curve cannot be definitely determined.
Suppose that taxes are decreased and the central bank conducts an autonomous easing of monetary policy. What will be the result?
The IS curve shifts right, the MP curve shifts down, and the AD curve shifts right.
Suppose that a new Fed chair is appointed, and his or her approach to monetary policy can be summarized by the following statement: "I care only about increasing employment; inflation has been at very low levels for quite some time; my priority is to ease monetary policy to promote employment." How would you expect the monetary policy curve to be affected, if at all? What would be the effect on the aggregate demand curve?
The MP curve will shift downward because decreasing unemployment results in a loosening of monetary policy. The AD curve will shift to the right.
What would be the effect of a decrease in U.S. net exports on the aggregate demand curve?
The aggregate demand curve shifts to the left
How do changes in planned expenditures affect the aggregate demand curve?
The aggregate demand curve shifts to the right if autonomous consumption, autonomous investment, autonomous net exports, or government purchases increase, or if taxes decrease.
How does an autonomous tightening or easing of monetary policy by the Fed affect the MP curve?
When the Fed decides to raise the real interest rate at any given inflation rate, the MP curve shifts upward. Monetary policy easing, a decision to lower the real interest rate at any given inflation rate, shifts the MP curve downward.
How is an autonomous tightening or easing of monetary policy different than a change in the real interest rate due to a change in the current inflation rate?
With a tightening or easing of monetary policy, some projected changes in monetary policy independent of the current inflation rate may occur.
The Fed's decision to shift the MP curve downward came from its belief that the financial crisis had the potential to drive the economy into a ________
deep recession
If net exports were not sensitive to changes in the real interest rate, would monetary policy be more or less effective in changing output? Monetary policy would be____ effective in changing output because net exports: A. are usually insensitive to changes in the real interest rate. B. represent an additional channel through which interest rate changes can affect output. C. are negatively correlated with the real interest rate and output. D. do not have any significant impact on output.
less; B
Taylor Principle
the principle that the monetary authorities should raise nominal interest rates by more than the increase in the inflation rate holds when λ>0.
The MP curve is ____ sloping due to the Taylor principle.
upward
Any factor that shifts the __________ curve shifts the __________ curve in the __________ direction.
IS; AD; same
