Locate a news article that describes an event that would cause a shift in the Aggregate Demand (Aggregate Expenditure). Describe if the event would cause an “upward” or “downward” shift in the Aggregate Demand curve and why. Briefly explain how this then fits within the Consumption Function.
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.

QUESTION 4
The figure below shows the planned Aggregate Expenditure function for a hypothetical economy
(AEp = 1,000 + 0.5 * Y). In this economy, taxes and transfers are equal to zero, so YD =Y. What
is the value of unplanned investment expenditure (Iµ) when GDP = 3,000? Suppose that, next
period, autonomous consumption increased by 100 and every thing else remained the same.
Under these new circumstances, what would the value of unplanned investment be when GDP =
3,000?
