Due to an increase in consumer wealth, there is a $40 billion autonomous increase in consumer spending in the economies of Westlandia and Eastlandia. Assuming that the aggregate price level is constant, the interest rate is fixed in both countries, and there are no taxes and no foreign trade, complete the accompanying tables to show the various rounds of increased spending that will occur in both economies if the marginal propensity to consume is 0.5 in Westlandia and 0.75 in Eastlandia. What do your results indicate about the relationship between the size of the marginal propensity to consume and the multiplier?
If you make $800 from a lucrative side business selling snack food in dorms, how much would you save if your marginal propensity to consume is 0.75? (do not include the dollar sign in your answer).

People spend 11% of every dollar on imports. What is the marginal propensity to consume in this economy? Write your answer as a number, between 0 and 1. If you think the answer is 0, write 0.00, not 0. Answer: Study the graph below. When will the multiplier be biggest? Select one: The multiplier will be the same size no matter what Aggregate Demand is b. The multiplier will be one no matter what aggregate demand is When aggregate demand is at AD1 d. When aggregate demand is at AD3 e When aggregate demand is at AD2 Price Level AD₁ AS e All of these are true AD₂ AD₁ GDP Why is potential output called potential, when it is not actually the most the economy can produce?

The marginal propensity to consume (MPC) for this economy is Suppose the government in this economy decides to decrease government purchases by $400 billion. The decrease in government spending will lead to a decrease in income, creating an initial change in consumption equal to This decreases income yet again, leading to a second change in consumption equal to The total change in demand resulting from the initial change in government spending is The following graph shows the aggregate demand curve (AD₁) for this economy before the change in government spending. Use the green line (triangle symbol) to plot the new aggregate demand curve (AD₂) after the multiplier effect takes place. For simplicity, assume that there is no "crowding out." Hint: Be sure that the new aggregate demand curve (AD2) is parallel to the initial aggregate demand…arrow_forward
