Assume that the money demand function is (M / P)d = 2,200 - 200r, where r is the interest rate in percent. If the price level is fixed at P=2, and the Fed wants to fix the interest rate at 7 percent, it should set the money supply at: 2,000. 1,800. 1,600. 1,400.

If the IS curve is given by Y = 1,700 - 100r, the money demand function is given by (M/P)d = Y - 100r, the money supply is 1,000, and the price level is 2, then if the money supply is raised to 1,200, equilibrium income rises by: 200 and the interest rate falls by 2 percent. 100 and the interest rate falls by 1 percent. 50 and the interest rate falls by 0.5 percent. 200 and the interest rate remains unchanged.

The economic response to the overnight reduction in the French money supply by 20 percent in 1724: 1. confirmed the neutrality of money because no real variables were affected by this nominal change. 2. confirmed the quantity theory by leading to an immediate 20 percent reduction in the price level. 3. confirmed that money is not neutral in the short run because both output and prices dropped. 4. contradicted Okun's law because decreases in output were not associated with increases in unemployment.

confirmed that money is not neutral in the short run because both output and prices dropped.

The reason that the income response to a fiscal expansion is generally less in the IS-LM model than it is in the Keynesian-cross model is that the Keynesian-cross model assumes that: 1. investment is not affected by the interest rate, whereas in the IS-LM model fiscal expansion raises the interest rate and crowds out investment. 2. investment is not affected by the interest rate, whereas in the IS-LM model fiscal expansion lowers the interest rate and crowds out investment. 3. investment is autonomous, whereas in the IS-LM model fiscal expansion encourages higher investment, which raises the interest rate. 4. the price level is fixed, whereas in the IS-LM model it is allowed to vary.

investment is not affected by the interest rate, whereas in the IS-LM model fiscal expansion raises the interest rate and crowds out investment.
