A flatter aggregate consumption function, if plotted on a graph with output on the horizontal axis and aggregate consumption on the vertical axis, would indicate which of the following: Select one: a. A smaller marginal propensity to consume and a larger multiplier. b. A larger marginal propensity to consume and a larger multiplier. c. A smaller marginal propensity to consume and a smaller multiplier. d. A smaller marginal propensity to save (MPS = 1 - MPC) and a smaller multiplier.

In an economy with no government and no foreign sectors, autonomous consumer spending is $250 billion, planned investment spending is $350 billion. Suppose that in general, consumers save a third of any additional disposable income they have. Plot the aggregate consumption function and planned aggregate spending.
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.
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 $400 billion and consumption was $300 billion. On the following graph, use the blue line (circle symbol) to plot this economy's consumption function based on these data.
(Multipliers) Suppose investment, in addition to having an autonomous component, also has a component that varies directly with the level of real GDP. How would this affect the size of the spending multiplier?
According to the multiplier concept when there is a change in any one of the components of total expenditures (C, I, G, or X-IM), a multiple impact upon: a) the rate of unemployment will occur. b) saving in the economy will occur. c) household expenditures will occur. d) income will occur.
