According to the aggregate demand and aggregate supply

Question

Question 1: Historical evidence for the U.S. economy indicates that

• recessions have occurred roughly once every six years since the 1960s.
• the unemployment rate usually decreases during a recession and increases shortly after the recession ends.
• real GDP usually remains roughly constant during a recession and decreases shortly after the recession ends.
• changes in real GDP over the business cycle are largely attributable to changes in investment over the business cycle.

Question 2: Which of the following is most commonly used to monitor short-run changes in economic activity?

• the inflation rate
• real GDP
• aggregate demand
• aggregate supply

Question 3: During recessions investment

• falls by a larger percentage than GDP.
• falls by about the same percentage as GDP.
• falls by a smaller percentage than GDP.
• falls but the percentage change is sometimes much larger and sometimes much smaller

Question 4: The classical model is appropriate for analysis of the economy in the

• long run, since evidence indicates that money is not neutral in the long run.
• long run, since real and nominal variables are essentially determined separately in the long run.
• short run, provided money is not neutral.
• short run, provided real and nominal variables are highly intertwined.

Question 5: Real and nominal variables are highly intertwined, and changes in the money supply change real GDP. Most economists would agree that this statement accurately describes

• both the short run and the long run.
• the short run, but not the long run.
• the long run, but not the short run.
• neither the long run nor the short run

Question 6: Aggregate demand includes

• the quantity of goods and services both the government and customers abroad want to buy.
• the quantity of goods and services neither the government nor customers abroad want to buy.
• the quantity of goods and service the government wants to buy, but not the quantity of goods and services customers abroad want to buy.
• the quantity of goods and services customers abroad want to buy, but not the quantity of goods and services the government wants to buy.

Question 7: The model of aggregate demand and aggregate supply

• is different from the model of supply and demand for a particular market, in that we cannot focus on the substitution of resources between markets to explain aggregate relationships.
• is different from the model of supply and demand for a particular market, in that we have to separate real and nominal variables in the aggregate model.
• is a straightforward extension of the model of supply and demand for a particular market, in which substitution of resources between markets is highlighted.
• is a straightforward extension of the model of supply and demand for a particular market, in which the interaction between real and nominal variables is highlighted.

Question 8: When the price level falls the quantity of

• consumption goods demanded rises, while the quantity of net exports demanded falls
• consumption goods demanded and the quantity of net exports demanded both rise.
• consumption goods demanded and the quantity of net exports demanded both fall.
• consumption goods demanded falls, while the quantity of net exports demand rises.

Question 9: When the price level changes, which of the following variables will change and thereby cause a change in the aggregate quantity of goods and services demanded?

Question 10: Other things the same, a decrease in the price level makes the dollars people hold worth

• more, so they can buy more.
• more, so they can buy less.
• less, so they can buy more.

Question 11: When the price level falls

• households want to lend more, so the interest rate rises making the quantity of goods and services demanded rise.
• households want to lend more, so the interest rate falls, making the quantity of goods and services demanded rise.
• households want to lend more, so the interest rate rises, making the quantity of goods and services demanded fall.
• None of the above are correct.

Question 12: Other things the same, if the U.S. price level falls, then

• the supply of dollars in the market for foreign-currency exchange increases, so the exchange rate rises.
• the supply of dollars in the market for foreign-currency exchange increases, so the exchange rate falls.
• the supply of dollars in the market for foreign-currency exchange decreases, so the exchange rate rises.
• the supply of dollars in the market for foreign-currency exchange decreases, so the exchange rate falls.

Question 13: As the price level rises,

• the exchange rate falls, so net exports fall.
• the exchange rate falls, so net exports rise.
• the exchange rate rises, so net exports fall.

• the supply of money in a country is determined by the overall wealth of the citizens of that country.
• the interest rate adjusts to balance the supply of, and demand for, money.
• the interest rate adjusts to balance the supply of, and demand for, goods and services.

Question 34: While a television news reporter might state that "Today the Fed lowered the federal funds rate from 5.5 percent to 5.25 percent," a more precise account of the Fed's action would be as follows:

• "Today the Fed told its bond traders to conduct open-market operations in such a way that the equilibrium federal funds rate would decrease to 5.25 percent."
• "Today the Fed lowered the discount rate by a quarter of a percentage point, and this action will force the federal funds rate to drop by the same amount."
• "Today the Fed took steps to decrease the money supply by an amount that is sufficient to decrease the federal funds rate to 5.25 percent."
• "Today the Fed took a step toward contracting aggregate demand, and this was done by lowering the federal funds rate to 5.25 percent."

Question 35: People choose to hold a smaller quantity of money if

• the interest rate rises, which causes the opportunity cost of holding money to rise.
• the interest rate falls, which causes the opportunity cost of holding money to rise.
