The Federal Reserve was created
in 1913 by Congress
In the open-economy macroeconomic model, the supply of loanable funds comes from
national saving
As the price level rises
people are more willing to lend, so interest rates rise
Investment in
physical capital, like investment in human capital, has an opportunity cost.
In the open economy macroeconomic model, the price that balances supply and demand in the market for foreign-currency exchange model is the
real exchange rate
Other things the same, the aggregate quantity of goods demanded in the U.S. increases if
real wealth rises.
An increase in the budget deficit
reduces investment because the interest rate rises
Suppose that the MPC is 0.7, there is no investment accelerator, and there are no crowding-out effects. If government expenditures increase by $30 billion, then aggregate demand
shifts rightward by $100 billion.
Suppose the U.S. offered a tax credit for firms that built new factories in the U.S. Then
the demand for loanable funds would shift rightward, initially creating a shortage of loanable funds at the original interest rate.
During periods of expansion, automatic stabilizers cause government expenditures
to fall and taxes to rise
When a country experiences capital flight, its net capital outflow,
which is part of the demand for loanable funds, increases
Factors that shift the demand curve
1. income 2. price of related goods 3. expectations of future prices 4. number of buyers 5. tastes and preferences
In the graph of the money market, the money supply curve is
vertical. It shifts rightward if the Fed buys bonds.
If output is above its natural rate, then according to sticky-wage theory
workers and firms will strike bargains for higher wages. This increase in wages shifts the short-run aggregate supply curve left.
The Federal Open Market Committee is
the group at the Federal Reserve that sets monetary policy
If the reserve ratio is 5 percent, then $600 of additional reserves can create up to
$12,000 of new money
If the interest rate is 7.5 percent, then what is the present value of $4,000 to be received in 6 years?
$2,591.85
If M = 9,000, P = 6, and Y = 1,500, what is velocity?
1
If velocity = 5, the price level = 2, and the real value of output is 2,500, then the quantity of money is
1,000
Suppose that in a closed economy GDP is 11,000, consumption is 7,500, and taxes are 500. What value of government purchases would make national savings equal to 2,000 and at that value would the government have a deficit or surplus?
1,500 deficit
Factors that shift the supply curve
1. input/resource prices 2. technology 3. taxes 4. expectations of future prices 5. number of sellers
The nominal exchange rate is 2 Barbados dollars per U.S. dollar. If the price of a good in Barbados is 3 Barbados dollars and the price in the U.S. is 2 U.S. dollars, what is the real exchange rate to the nearest 100th?
1.33 Barbados goods per U.S. good
Two of the economy's most important financial intermediaries are
Banks and mutual funds
Part of the explanation for why the aggregate-demand curve slopes downward is that a decrease in the price level
Decreases the interest rate
The interest rate that the Fed charges banks that borrow reserves from it is the
Discount rate
The interest rate that the Federal Reserve pays banks on the reserves they hold is called the
Excess reserves
The banking system currently has $200 billion of reserves, none of which are excess. People hold only deposits and no currency, and the reserve requirement is 4 percent. If the Fed raises the reserve requirement to 10 percent and at the same time buys $50 billion worth of bonds, then by how much does the money supply change?
Falls by $2,500 billion
If Japan has an absolute advantage in the production of an item, it must also have a comparative advantage in the production of that item.
False
In the open-economy macroeconomic model, other things the same, an increase in the exchange rate raises the quantity of dollars supplied in the market for foreign-currency exchange.
False
The claim that increases in the growth rate of the money supply increase nominal interest rates but not real interest rates is known as the
Fisher effect
What would happen in the market for loanable funds if the government were to decrease the tax rate on interest income?
There would be an increase in the amount of loanable funds borrowed.
A country with a larger GDP per person generally has a greater standard of living or quality of life than a country with a smaller GDP per person.
True
Absolute advantage is a comparison among producers based on productivity.
True
An increase in the price of imported cameras is captured by the CPI but not by the GDP deflator.
True
Comparative advantage is a comparison among producers based on opportunity cost.
True
For an economy as a whole, income equals expenditure because the income of the seller must be equal to the expenditure of the buyer.
True
If U.S. GDP exceeds U.S. GNP, then foreigners produce more in the United States than U.S. citizens produce in the rest of the world.
True
If U.S. residents purchase $450 billion of foreign assets and foreigners purchase $575 billion of U.S. assets, then the U.S. has net capital outflows of -$125 billion and a trade deficit of $125 billion.

both the one in Ohio and the one in Italy
Higher inflation
causes firms to change prices more frequently and makes relative prices more variable.
comparative advantage
comparative advantage compares opportunity costs of production for each producer. The producer with the lower opportunity cost of production is said to have a comparative advantage
M1 includes
currency, demand deposits, travelers checks
Which list ranks assets from most to least liquid?
currency, stocks, fine art
If expected inflation is constant and the nominal interest rate decreases by 2 percentage points, then the real interest rate
decreases by 2 percentage points
Diversifying
decreases the standard deviation of the value of a portfolio indicating its risk has decreased.
Discounting refers directly to
finding the present value of a future sum of money.
Productivity is defined as the quantity of
goods and services produced from each unit of labor input
According to liquidity preference theory, the money-supply curve would shift rightward
if the Federal Reserve chose to increase the money supply
Suppose that in a country people gain more confidence in the banking system and so hold relatively less currency and more deposits. As a result, bank reserves will
increase and the money supply will eventually increase.
Unemployment insurance tends to
increase frictional unemployment
Suppose that roofers are not unionized. If roofers unionize, then the supply of labor in other sectors of the economy will
increase, reducing wages in industries that are not unionized.
If a country went from a government budget deficit to a surplus, national saving would
increase, shifting the supply of loanable funds right.
Suppose monetary neutrality holds and velocity is constant. A 4 percent increase in the money supply
increases price level by 4%
Aggregate demand shifts right when the Federal Reserve
increases the money supply
If U.S. citizens decide to purchase more foreign assets at each interest rate, the U.S. real interest rate
increases, the real exchange rate of the dollar depreciates, and U.S. net capital outflow increases.
If the U.S. price level is increasing by 3 percent annually and the Japanese price level is increasing by 1 percent annually, then according to purchasing-power parity, by about what percent would the nominal exchange rate be changing?
increasing by 2 percent
If a country exports more than it imports, then it has
positive net exports and positive net capital outflows
Velocity is computed as the
price level times real GDP divided by the money supply
A nation's standard of living is determined by
productivity of its workers
In 2002 it looked like the Argentinean government might default on its debt (which eventually it did). The open-economy macroeconomic model predicts that this should have
raised Argentinean interest rates and caused the Argentinean currency to depreciate.
The investment component of GDP measures spending on
residential construction, business equipment, business structures, and changes in inventory. During recessions it declines by a relatively large amount.
Other things the same, an increase in taxes with no change in government purchases makes national saving
rise. The supply of loanable funds shifts right
When inflation rises, the nominal interest rate
rises, and people desire to hold less money
If the interest rate is below the Fed's target, the Fed would
sell bonds to decrease the money supply.
If the federal funds rate were below the level the Federal Reserve had targeted, the Fed could move the rate back towards its target by
selling bonds. This selling would reduce the money supply
People hold money primarily because it
serves as a medium of exchange
Liquidity preference theory is most relevant to the
short run and supposes that the interest rate adjusts to bring money supply and money demand into balance.
Menu costs help explain
sticky-price theory
If the Federal Reserve increases the money supply, then initially there is a
surplus in the money market, so people will want to buy bonds.
Which of the following would both shift aggregate demand right?
taxes decrease and government expenditures increase.
Other things the same, the aggregate quantity of goods demanded in the U.S. increases if
the dollar depreciates
Other things the same, the aggregate quantity of goods demanded in the U.S. increases if
the dollar depreciates.
Liquidity refers to
the ease with which an asset is converted into a medium of exchange.
Using the liquidity-preference model, when the Federal Reserve decreases the money supply,
the equilibrium interest rate increases.
Suppose government expenditures on goods and services increase, transfers are unchanged, and taxes rise by less than the increase in expenditures. These changes in the government's budget cause
the equilibrium interest rate to rise and the equilibrium quantity of loanable funds to fall
Other things the same, if foreign residents desired to purchase more U.S. wheat
the exchange rate would rise and net exports would be unchanged

the value of foreign assets purchased by domestic residents - the value of domestic assets purchased by foreigners
An increase in the budget deficit causes domestic interest rates
to rise and investment to fall.
An decrease in taxes shifts aggregate demand
to the right. The larger the multiplier is, the farther it shifts.

Price takers
If a market is perfectly competitive, both buyers and sellers are said to be price takers because they cannot influence the price.
ambiguous
If both supply and demand shift at the same time and we do not know the magnitude of each shift, then the change in either the price or the quantity must be ambiguous
Surplus in market
If the price is above the equilibrium price, the quantity supplied exceeds the quantity demanded, and there is a surplus, or an excess supply, of the good. A surplus causes the price to fall until it reaches equilibrium
Shortage in market
If the price is below the equilibrium price, the quantity demanded exceeds the quantity supplied, and there is a shortage, or an excess demand for the good. A shortage causes the price to rise until it reaches equilibrium.
Complements- demand curve
If two goods are used together, they are known as complements. When two goods are complements, an increase in the price of one good leads to a decrease in the demand for the other good.
substitutes- demand curve
If two goods can be used in place of one another, they are known as substitutes. When two goods are substitutes, an increase in the price of one good leads to an increase in the demand for the other good.
Marcus is of the opinion that the theory of liquidity preference explains the determination of the interest rate very well. Most economists would say that Marcus's opinion is
