- We found that for every $1 increase in G there is a multiplied impact on output with, in the most 1 basic model, a multiplier of A study by economists at the New York Fed conducted 1- MPC during the COVID-19 recession found that "as of the end of June 2020, a relatively small share of stimulus payments-ljust] 29 percent-was used for consumption." What is the G multiplier based on that estimated MPC and the formula from the basic model?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. O In the Keynesian Model, consumers will increase their spending by the mpc times the increase in income. In the Life-Cycle/Permanent Income Model, consumers will only increase their spending if they believe that the increase in their income…Suppose that due ot a fiscal stimulus, there is an increase in disposable incomes of $100 billion in the first round. Then, $33 billion was spent in consumption from this initial change of the disposable incomes. Following the same marginal propensity to consume, how much is the change in consumption spending in the next round from the $33 billion?
- Consider an economy that is operating atthe full-employment level of real GDP.Assuming the MPC is 0.90, predict the effect onthe economy of a $50 billion increase in governmentspending balanced by a $50 billionincrease in taxes.Use the Keynesian cross to predict the impacton equilibrium GDP of the following. In eachcase, state the direction of the change and give aformula for the size of the impact.a. An increase in government purchasesb. An increase in taxesc. Equal-sized increases in both governmentpurchases and taxesHelp 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
- A fall in mps raises the GDP multiplier. O True O Falsen the Keynesian cross, assume that the consumption function is given byC = 200 + 0.75 (Y - T).Planned investment is 100; government purchasesand taxes are both 100.a. Graph planned expenditure as a function ofincome.b. What is the equilibrium level of income?c. If government purchases increase to 125, whatis the new equilibrium income?d. What level of government purchases is neededto achieve an income of 1,600?The marginal propensity to consume (MPC) for this econamy is . and the spending multiplier for this economy is Suppose the govemment in this economy decides to decrease govemment purchases by $250 bilion. The decrease in government purchases will lead to a decrease in income, generating an initial change in consumption equal to second change in consumption equal to This decreases income yet again, causing a The total change in demand resulting from the initial change in government spending is The following graph shows the aggregate demand curve (AD ) for this economy before the change in govemment spending. Use the green line (trangie symbol) to plot the new aggregate demand curve (AD:) after the multiplier effect takes place. For simplioity, assume that there is no "crowding out." Hint: Be sure that the new aggregate demand curve (AD) is paralel to the initial aggregate demand curve (AD). You can see the slope of AD by selecting t on the graph. 540 AD.

(b) Compute the marginal propensity to consume. (c) Compute the government expenditures multipler. (d) Suppose net export increases by $400 (Assuming MPC, Gevernment Purchases, and Planned Investment are the same). What will be the new equilibrium level of GDP? Consumption?Which of the following statements is true according to Keynesian economic theory? O If the government increases spending by $10 million, the aggregate demand will eventually increase by $10 million. O If the government increases spending by $10 million, the aggregate demand will eventually decrease by $10 million. O If the government increases spending by $10 million, the aggregate demand will eventually decrease by more than $10 million. If the government increases spending by $10 million, the aggregate demand will eventually increase by more than $10 million.
