Which of the following is NOT one of the possible causes of price changes, as revealed through the quantity theory of money?
A change in interest rates
The consumer price index (CPI) measures the average price that a typical _____ faces for a basket of goods and services.
American consumer
Changes to both the money supply and the velocity of money induce changes in aggregate demand. However, the long-run impacts of changes in these variables are different. How are the effects of an increase in the velocity of money and the effects of an increase in the money supply different?
Changes in the money supply can lead to permanent changes in aggregate demand, but changes in the velocity of money tend to have temporary changes in aggregate demand.
Which situation is NOT a consequence of price signals being difficult to interpret because of inflation?
Consumers respond to real prices instead of to nominal prices. -leads to money illusion
Which growth rate is NOT necessarily the same as the others?
Correct-the real growth rate(GDP) the potential growth rate the long-run trend growth rate the Solow growth rate
Which of the following factors impacts the velocity of money in the economy?
How long it takes for a check to clear
Which country had the largest episode of hyperinflation on record?
Hungary
True statement pt8
If the rate of spending growth is 10% and the Solow growth rate is 4%, then the rate of inflation must be 6%. This is correct: 10% = 4% + 6%.
What impact does an increase in the expected inflation rate have on the SRAS curve?
It shifts the SRAS curve up and to the left.
What feature of the economy's output does gross domestic product measure?
Its market value
From the equation of exchange, 𝑀𝑉=𝑃𝑌MV=PY, we know that spending growth (𝑀−→+𝑣→)(M→+v→) equals inflation 𝜋+π+ Real growth. Recall from the chapter that in the long run (1) the inflation rate is found where the AD curve intersects the LRAS curve (reading off the vertical axis) and (2) the expected inflation rate is found where the short-run aggregate supply curve intersects the LRAS curve. With these things in mind, assume that the Solow growth rate is 3%. If spending growth equals 10%, what will 𝜋π equal in the long run? What will 𝐸𝜋Eπ equal?
M + V = 𝜋 + Real Growth Rate 10% = 3 10-3= 𝜋=7 𝐸𝜋=7
Equation of Exchange
M × v = P × YR M=money supply v= velocity of money p=price level
When the government is spending more than it collects in tax revenue, it goes into debt to finance the spending. If the government then pays off its debt by printing money, this is referred to as:
Monetizing the debt
If M × v = P × YR, then it must also be true that M+V =P +Yr
Money , velocity, percentage, and something else.
Is the value of the production of intermediate goods missing from GDP?
No, because the value of these goods is part of the value of some other finished goods.
Which rewritten version of the quantity theory of money does Professor Tabarrok use to discuss the causes of inflation?
P = Mv ÷ Y
Correct statement
Prices are signals, and inflation makes price signals harder to interpret.
True statement pt4
The Solow growth curve is vertical, because the potential growth rate does not depend on the rate of inflation.
Which of the following factors decreases aggregate demand?
decreased export growth
A negative AD shock:
decreases the real growth rate at first, but in the long run decreases only the rate of inflation.
Assume the average price level was 104 in 2016 and 101 in 2017. If the inflation rate was 3.96% in 2016, then the __________ rate in 2017 is _____________.
deflation; −2.88%
The velocity of money:
does not change enough to explain large, sustained changes in prices.
Producer price indexes (PPIs) measure the average price:
received by producers.
Suppose that for an imaginary economy, the velocity of money is equal to 6 and the money supply is $1.5 billion. If the price level in this economy is equal to 2, the real GDP in this economy is equal to:
($1.5 billion × 6) ÷ 2.00 = $9 billion ÷ 2.00 = $4.5 billion.
Positive Shocks (Increase AD) (= Higher Growth Rate of Spending)
-A faster money growth -Confidence -Increased wealth -Lower taxes Greater growth of government spending -Increased export growth -Decreased import growth
Negative Shocks (Decrease AD) (= Lower Growth Rate of Spending)
-A slower money growth -Fear -reduced wealth -Higher taxes -Lower growth of government spending -Decreased export growth -Increased import growth
Which of the following statements is TRUE?
-If the price level is 105 in 2016 and is 107 in 2017, then the inflation rate is 7%. -The GDP deflator is calculated as the ratio of real to nominal GDP multiplied by 100. -Real prices(nominal prices=CA) are not adjusted for inflation. -##The development of new goods and better-quality goods has led some economists to suggest that the CPI may actually overstate inflation.
Which condition is mentioned in the textbook as a real shock that contributed to the Great Depression?
-economic policy mistakes A tariff, for example, pushes capital and labor into lower-productivity sectors, thereby reducing total output.
Unexpected inflation always:
...turns into expected inflation.
If for a certain economy the growth rate of the money supply is 5%, the growth rate of the velocity of money is _____, the rate of inflation is 3%, and the real growth rate is 2%, then the quantity theory of money holds.
0%
If for a certain economy the growth rate of the money supply is 4%, the growth rate of the velocity of money is 0%, the rate of inflation is 3.2%, and the real growth rate is ______, then the quantity theory of money holds.
0.8% This is because 4 + 0 = 3.2 + 0.8.
Suppose that for an imaginary economy, the velocity of money is equal to 6 and the money supply is $1.8 billion. The nominal GDP of this economy is:
10.8 million Nominal GDP is $1.8 billion × 6 = $10.8 billion. Real GDP is nominal GDP divided by the price level.
According to the AD curve, if M is 4%, V is 2%, and the real growth rate is 3%, what must be the rate of inflation?
3% 4+2=3+?
From the equation of exchange, 𝑀𝑉=𝑃𝑌MV=PY, we know that spending growth (𝑀−→+𝑣→)(M→+v→) equals inflation 𝜋+π+ Real growth. Recall from the chapter that in the long run (1) the inflation rate is found where the AD curve intersects the LRAS curve (reading off the vertical axis) and (2) the expected inflation rate is found where the short-run aggregate supply curve intersects the LRAS curve. With these things in mind, assume that the Solow growth rate is 3%. If spending growth equals 4%, what will 𝜋π equal in the long run? What will 𝐸𝜋Eπ equal?
4-3 𝜋=1 𝐸𝜋=1
According to the AD curve, if V is 0, the rate of inflation is 2%, and the rate of real growth is 3%, then what M must be?

The dynamic aggregate demand (AD) curve is modeled as a downward-sloping line. Which of the statements is the best explanation for why the dynamic AD has this shape?
A proportional increase in inflation for every decrease in the growth rate is required to keep the growth in spending constant.
What is a real price?
A real price refers to a price that has been adjusted to account for inflation.
Dynamic aggregate demand (AD) can be derived using the quantity theory of money. Suppose that the velocity of money is stable, 4% real economic growth is occurring, the rate of inflation is 4%, unemployment is 5.3%, and the marginal propensity to save is 3%. By how much is the money supply growing? Enter your answer as a percentage.
Equation: Growth in the money supply + growth in velocity = inflation + real economic growth 3%=4%+4% 8%

The velocity of money will decrease.
What impact will an increase in the money supply have on the AD curve?
There is not enough information to determine the impact on aggregate demand. (An increase in the growth of the money supply will increase aggregate demand, but no information about the growth rate has been given; this question says only that the variable itself (not its growth rate) increases.)
What impact will a reduction in wealth have on the AD curve?
There will be a decrease in aggregate demand.
What impact will a slower money growth rate have on the AD curve?
There will be a decrease in aggregate demand.
What impact will an increase in export growth have on the AD curve?
There will be an increase in aggregate demand.
A decrease in velocity, ceteris paribus, will shift the AD curve down and to the left.
True statement
Which of the following statements is TRUE? pt7
True- In the short run, an increase in spending growth is split between increases in inflation and increases in real growth. When unexpected inflation becomes expected inflation, it causes no change in the SRAS curve. A spending increase creates a permanent increase in growth. Prices move instantly to their new long-run equilibrium, thus preventing any increase in growth brought about by a spending increase.
True statement pt2
When unexpected inflation becomes expected inflation, it causes the SRAS curve to shift.
Which of the following statements is FALSE?
X-If the money supply is $4,000, velocity is stable at 12, and the average price level is 80, then real GDP is $600. C-Nominal GDP in the long run is determined by capital, labor, and technology, none of which is affected by the price level. X-If velocity is stable at 9 and nominal GDP is $18,000, then the money supply must equal $2,000. X-If the money supply is $6,000, the average price level is 90, and real GDP is $900, then velocity is 13.5.
Which of the following statements is TRUE? pT2
X-The investment rate is the percentage change in the average level of prices, as measured by a price index, over a specific period. X-Inventory is an increase in the average level of prices. X-The producer price index measures the average price of a basket of goods and services bought by a typical American consumer. C-A real price has been corrected for inflation.

an increase in the money supply, since real GDP and the velocity of money are relatively stable.
What is inflation?
an increase in the overall price level
Economies:
are continually hit by many small shocks. In a typical year, the good shocks outweigh the bad shocks, and the economy grows.

real shock
Assume the average price level was 101 in 2016 and 105 in 2017. The __________ rate is _____________.
inflation; 3.96% The inflation rate is [(105 − 101) ÷ 101] ×100 = 3.96%.
If the federal government decides to increase spending to stimulate the economy, then the growth rate of government spending will:
initially rise and then return to its normal growth rate. (If the growth rate of government spending were permanently increased, government spending would eventually be greater than GDP, which is not possible.)
Suppose that for an imaginary economy, the velocity of money is equal to 8 and the money supply is $1.2 billion. The real GDP of this economy is:
less than $9.6 billion if the price level is greater than 1. Nominal GDP is $1.2 billion × 8 = $9.6 billion. Real GDP is nominal GDP divided by the price level.
One of the reasons that the government is not likely to resort to monetizing its debt is that:
many bondholders are also voters, who would be angry if high inflation reduced the rate of return on their bonds.
The producer price index
measures the average price received by producers.

A price that has been corrected for inflation is referred to as a:
real price
When inflation occurs, it is usually the case that in the short run:
some prices have gone up and others have fallen. At any one point in time, some prices are going up and some are going down.
The "inflation rate" is:
the percentage change in the average level of prices over a specific period. The formula for the inflation rate is (P2 − P1) ÷ P1.
