Consider the multiplier model. Compare two economies, which differ only in the share of credit-constrained households, but are otherwise identical. In which economy is the multiplier larger? Use a diagram to explain your answer. ii. Based on the previous reasoning, would you expect the size of the multiplier to be larger in expansions or recessions? Why?

Multiplier Effect Question, Initial investment of 2 billion and getting 9 billion in total revenue after reinvestment

Which of the following correctly describes how a decrease in the price level affects consumption spending? Select one: a. A decrease in the price level raises real wealth, which causes consumption to increase. b. A decrease in the price level decreases the amount of money a household needs to buy goods and so raises the interest rate, which causes consumption to increase. c. A decrease in the price level increases the amount of money a household needs to buy goods and so raises the interest rate, which causes consumption to increase. d. A decrease in the price level lowers real wealth, which causes consumption to decrease.

1. Graphing the consumption function from the MPC Consider a hypothetical economy in which the marginal propensity to consume (MPC) is 0.50. That is, if disposable income increases by $1, consumption increases by 50¢. Suppose further that last year disposable income in the economy was $450 billion and consumption was $350 billion. On the following graph, use the blue line (circle symbol) to plot this economy's consumption function based on these data. CONSUMPTION (Billions of dollars) 700 600 500 400 300 200 100 0 -100 0 100 200 300 400 500 600 DISPOSABLE INCOME (Billions of dollars) 700 800 (?) From the preceding data, you know that the level of saving in the economy last year was $ economy is billion and the marginal propensity to save in this Suppose that this year, disposable income is projected to be $550 billion. Based on your analysis, you would expect consumption to be S billion and saving to be $ billion.

Spending Round by Round Complete the following questions. 1. Assume the MPC is 0.75. What is the value of the multiplier? What is the MPS? What would need to happen to make the multiplier larger? 2. Assume investment spending increases by $20 billion and the MPC is 0.75. Calculate the first through the fourth rounds of spending in the economy. 3. Assume investment spending increases by $20 billion and the MPC is 0.75. Calculate the total change in GDP arising from this increase in investment spending.

Which best describes why the multiplier exists? When people spend money, that money ends up in the pockets or bank accounts of other people or organizations, who then use that money in some way. The multiplier exists because money spent today is always more valuable than money spent in the future, due to inflation and interest rates. When people see other people spending money, they know that the economy is about to improve, leading them to spend more money. When people see the government spending more money, they realize that the government thinks that prices are low; thus, they believe it is a good time to buy things.
