According to the Keynesian model of a depression, a. an increase in investment was the primary cause of the 1929-1933 Depression O b. a decrease in investment provided the best hope of recovery from the 1929-1933 Depression O c. an increase in government expenditures provided the best hope of recovery from the 1929-1933 Depression O d. an increase in investment provided the best hope of recovery from the 1929-1933 Depression e. large government budget deficits were the cause of the 1929-1933 depression When the velocity of money is constant, the quantity theory predicts that a. The inflation rate is constant O b. Inflation rate = Growth rate of money supply - growth rate of real GDP c. The growth rate of real GDP = Growth rate of money supply + Inflation rate d. The inflation is greater than zero when the growth rate of money supply = growth rate of real GDP e. The inflation rate is positive when the growth rate of money supply is less than the growth rate of real GDP At every inflation rate and for a fixed expected inflation rate, when the money supply growth rate decreases, the money supply decreases after a while and a. Aggregate Quantity Demanded AQD decreases because real interest rates increase and investment decreases O b. Aggregate Quantity Demanded AQD increases because exports decrease O c. Aggregate Quantity Supplied AQS increases because real wages increase d. Aggregate Quantity Demanded AQD decreases because nominal wages increase e. Aggregate Quantity Demanded AQD falls because consumption increases
