Assume that the investment function is given by I = 1,000 - 30r, where r is the real rate of interest (in percent). Assume further that the nominal rate of interest is 10 percent and the inflation rate is 2 percent. According to the investment function, investment will be:
760

unit of account
In the United States, bank reserves consist of:
vault cash and deposits at the Federal Reserve
The nominal interest rate is the:
rate of interest that investors pay to borrow money.
The supply and demand for loanable funds determines the:
real interest rate
The one-to-one relation between the inflation rate and the nominal interest rate, the Fisher effect, assumes that the:
real interest rate is constant
If there is no currency and the proceeds of all loans are deposited somewhere in the banking system and if rr denotes the reserve-deposit ratio, then the total money supply is:
reserves divided by rr
When the demand for money parameter, k, is large, the velocity of money is ______ and money is changing hands ______
small;infrequently
In the classical model with fixed income, if households want to save more than firms want to invest, then:
the interest rate falls
If the ratio of reserves to deposits (rr) increases, while the ratio of currency to deposits (cr) is constant and the monetary base (B) is constant, then:
the money supply decreases
The rate of inflation is the:
percentage change in the level of prices
If disposable income is 4,000, consumption is 3,500, government spending is 1,000, and taxes minus transfers are 800, national saving is equal to:
300
Assume that the consumption function is given by C = 150 + 0.85(Y - T), the tax function is given by T = t0 + t1Y, and Y is 5,000. If t1 decreases from 0.3 to 0.2, then consumption increases by:
425
If income is 4,800, consumption is 3,500, government spending is 1,000, and taxes minus transfers are 800, private saving is:
500
The nominal interest rate is 1 percent and the inflation rate is 5 percent, the real interest rate is:
-4 percent
Assume that the consumption function is given by C = 200 + 0.7(Y - T), the tax function is given by T = 100 + t1Y, and Y = 50K0.5L0.5, where K = 100 and L = 100. If t1 increases from 0.2 to 0.25, then consumption decreases by:
175
