Refer to Figure 3. As we move from one point to another along the money-demand curve MD1,What shifts MD: money demand curve? Two factor shift money demand MD: P and Y. If P or Y goes up, MD increases and shifts to the right, and vice versa. If we are moving along MD1, P and Y have to stay fixed because if they don't, we would move to a different MD curve. a. the price level is held fixed at P1.->correct b. the interest rate is held fixed at r1.->incorrect because the interest rate changes if we move along the money demand MD curve. For example, if we move down along MD1, the interest would fall from r1 to another interest rate. c. the money supply is changing so as to keep the money market in equilibrium.->incorrect d. the expected inflation rate is changing so as to keep the real interest rate constant.->incorrect

a. the price level is held fixed at P1.->correct

Refer to Figure 2 8. Which of the following is correct? a. A wave of optimism could move the economy from point a to point b.-> moving from a to b implies that AD shifts left and total spending is decreasing. But optimism causes AD to shift to the right, so the statement is incorrect. b. If aggregate demand moves from AD1 to AD2, the economy will stay at point b in both the short run and long run.->The statement is incorrect because the economy will only stay at b in the SHORTRUN.
