The​ Fed's $2.2 trillion fire hose The Fed threw a lot of money at the financial crisis in 2008 to unfreeze credit markets and encourage economic activity. As part of its effort to keep the interest rate​ low, the Fed purchased government bonds worth​ $300 billion between March and September 2009. By​ October, the Fed held​ $770 billion in government​ securities, nearly double its​ pre-crisis total. Before the​ crisis, the Fed held mainly government​ securities, which it used to control the quantity of money in the economy. Now government securities make up just​ 35% of the​ Fed's balance sheet. ​Source: CNN​ Money, October​ 9, 2009 If the Fed purchased the government securities on the open​ market, explain why the purchase of​ $300 billion of government securities would influence the interest rate.

If the Fed purchases the government securities on the open​ market, the quantity of money​ ______ because​ _______. increases; bank reserves increase The nominal interest rate​ _______. falls

What is the opportunity cost of holding money?

The opportunity cost of holding money is the nominal interest rate. The nominal interest rate equals the real interest rate plus the inflation rate. When the​ inflation-adjusted rate of interest on bonds is 0​ percent, the real interest rate on bonds is 0 percent and the opportunity cost of holding a bond is equal to the nominal interest rate. So the returns on bonds and money are equal. But when the inflation rate rises and the real interest rate on bonds is guaranteed to be 0.1​ percent, the nominal interest rate exceeds the real interest rate received on bonds. So the return on bonds is greater than the return on holding money.

In the long run with a constant velocity of​ circulation, the inflation rate​ _______.

equals the money growth rate minus the growth rate of real GDP Money growth​ + Velocity growth​ = Inflation rate​ + Real GDP growth Rearranging Inflation rate​ = Money growth​ + Velocity growth−Real GDP growth With a constant velocity of circulation Inflation rate​ = Money growth−Real GDP growth

Sara has ​$500 in currency and ​$4,000 in a bank account on which the bank pays no interest. The inflation rate is 4 percent a year. Calculate the amount of inflation tax that Sara pays in a year.

(4,500*(1 - inflation rate [4 %]) = 4320. 4500 - 4320 = 180$ of "inflation tax." Sara is holding ​$500 in currency and ​$4,000 in her bank​ account, and she receives no interest on either her currency holding or her bank account. At the end of the​ year, her purchasing power is 4 percent less than at the beginning of the year because of the effects of inflation. The inflation tax that she pays is equal to the decrease in her purchasing​ power, which is 4 percent of her currency holding plus 4 percent of her bank account. So Sara pays an inflation tax of ​$180.

Why does an increase in real GDP increase the demand for money and changes in financial technology can increase the demand for money or decrease the demand for money

An increase in real GDP increases the demand for money and financial technology can increase the demand for money or decrease the demand for money. For​ example, daily interest checking deposits and automatic transfers between checkable deposits and saving deposits lower the opportunity cost of holding money and increase the demand for money. Credit cards that have made it easier for people to buy goods and services on credit and pay for them later have decreased the demand for money.

In 2000​, the Canadian economy was at full employment. Real GDP was $940 billion. The nominal interest rate was 7.0 percent a​ year, the inflation rate was 4.0 percent a year, the price level was 1.10​, and the velocity of circulation was 11.00. What was the quantity of money in Canada​?

In 2000​, the quantity of money in Canada is $94.0 billion.

Choose the correct statement.

Inflation is a tax on holding money.

What are some costs of inflation?

The costs of inflation include the tax on money held by individuals and​ businesses, the increased opportunity cost of holding​ money, and the cost of running around to compare prices at different outlets.

Sally has a credit card balance of ​$2,000. The credit card company charges a nominal interest rate of 18 percent a year on unpaid balances. The inflation rate is 7 percent a year. Calculate the real interest rate that Sally pays the credit card company.

The real interest rate is equal to the nominal interest rate minus the inflation rate. The real interest rate is 18 percent a year minus 7 percent a​ year, which is 11 percent a year.

In 2007​, the United States was at full employment. The quantity of money was growing at 6.4 percent a​ year, the nominal interest rate was 4.4 percent a​ year, real GDP grew at 1.9 percent a​ year, and the inflation rate was 2.9 percent a year. Was the velocity of circulation​ constant? [Hint: Use the quantity theory of​ money.] If the velocity of circulation was not​ constant, how did it change and why might it have​ changed?

The velocity of circulation decreased and its change was −1.6 percent a year. The change in the velocity of circulation occurred because​ the_______. growth rate of the quantity of money was greater than the growth rate of nominal GDP

Explain​ why, other things remaining the​ same, interest rates will rise the economy recovers from recession.

When real GDP​ increases, expenditures and incomes increase. To make the increased expenditures and income​ payments, households and firms must hold larger average amounts of money. The demand for money increases. The demand for money curve shifts rightward and the interest rate rises. In the​ figure, the demand for curve for money shifts rightward from MD0 to MD1 and the equilibrium nominal interest rate rises from 5 percent a year to 6 percent a year

The costs of inflation do not include​ _______.

an increase in saving and investment

The Fed decreases the quantity of money. In the short​ run, the quantity of money demanded​ ______ and the nominal interest rate​ ______.

decreases​; rises

​Inflation-adjusted savings bonds purchased from May through October 2009 will earn​ 0% for the first six months. The fixed interest rate on these bonds is​ 0.1% and over the previous 6​ months, inflation fell at an annual rate of​ 5.56%. The minimum interest rate on savings bonds is set at​ 0%. ​Source: USA Today​, May​ 5, 2009 Are these savings bonds a better deal than cash under the​ mattress? At an interest rate of 0​ percent, the return on the bonds​ ______ the return on money. If inflation starts to​ rise, and bonds receive a fixed interest rate of 0.1​ percent, the return on the bonds​ ______ the return on money.

Explain why businesses paid workers twice a day during the hyperinflation in Germany after World War I and why workers spent their incomes as soon as they were paid. Choose the correct statement.

(The longest one) Businesses paid workers twice a day so that employees would not leave their jobs and search for employment elsewhere. Workers spent their incomes as soon as they were paid to minimize the loss in value of their income.

In 1999​, the United Kingdom economy was at full employment. Nominal GDP was ​£770 ​billion, the real interest rate was 4 percent per​ year, the inflation rate was 3 percent a​ year, and the price level was 110. Calculate the nominal interest rate.

The nominal interest rate is 7 percent a year. (Nominal equals real interest rate + inflation rate) In the long​ run, if the real interest rate remains the same but the inflation rate increases to 4 percent a​ year, then the nominal interest rate increases to 8 percent a year.

Sally has a credit card balance of ​$5,000. The credit card company charges a nominal interest rate of 19 percent a year on unpaid balances. The inflation rate is 10 percent a year. Calculate the real interest rate that Sally pays the credit card company.

The real interest rate is equal to the nominal interest rate minus the inflation rate. The real interest rate is 19 percent a year minus 10 percent a​ year, which is 9 percent a year.

Sally has a credit card balance of ​$10,000. The credit card company charges a nominal interest rate of 17 percent a year on unpaid balances. The inflation rate is 9 percent a year. Calculate the real interest rate that Sally pays the credit card company.

The real interest rate that Sally pays the credit card company is 8 percent a year.
