Inventories typically increase starting at the beginningof recessions, and begin to decline near the end ofrecessions. What does this say about the relationshipbetween planned spending and aggregate output overthe business cycle?
The Life-Cycle/Permanent Income Model of Consumption makes a different prediction from the Keynesian Model, about how Consumption reacts to an increase in current income. Which of the following is the best description of the difference? O In the Keynesian Model, consumers will increasktheir spending by the mpc times the increase in income. In the Life-Cycle/Permanent Income Model, consumers will not increase their spending by much unless they believe that the increase in their income is permanent. O In the Life-Cycle/Permanent Income Model, consumers will increase their spending by the mpc times the increase in income. In the Keynesian Model, consumers will only increase their spending if they believe that the increase in their income is temporary.

Help The aggregate demand curve can be derived from the aggregate expenditures model as indicated by the fact that Multiple Choice an increase in the price level shifts the aggregate expenditures schedule upward and increases real GDP a decrease in the price level shifts the aggregote expenditures schedule downward and decreases real GDP a decreose in the price level shifts the aggregate expenditures scheduie upiward and decreases real GDP an increase in the price level shifts the eggregate expenditures schedule downverd and decreases real GDP
Consider a keynesian macromodel Y=(C0+G+I) / (1-c) where C0 is autonomus consumption, G is government consumption expenditure, I is investment expenditure, c is the marginal propensity to consume. In this model, if lthere is an increse in both labor productivity and the marginal propensity to consume while autonomus expenditures remain unchanged, what will happen to the level of employment? a. can't say for sure b. decreses c. stays the same d. increases
Which of the following will NOT shift the ADT curve? O a. A rise in government spending O b. A rise in exports Ос. A rise in interest rates O d. A rise in consumer confidence
