The following table shows data for the economy before the decrease in saving. Suppose that the decrease in saving causes consumption to rise from $280 million to $320 million. Assume Say's law holds in this economy. Fill in the data for the economy after the decrease in saving. Consumption (C) Investment (I) Government Purchases (G) Exports (EX) Imports (IM) Before Saving Decrease $280 million $200 million $250 million $500 million $300 million As a result of the decrease in saving, total expenditures will After Saving Decrease $320 million $ $ million million $500 million $300 million

Assume an economy has a consumption function of C = 0.87 (Yd) + $270.18. Additionally, this economy has investment spending = $878.78, government purchases $299.38, taxes = $111.59, exports = $209.28, and imports $289.40. What is the equilibrium level of GDP based on this information? Round your answer to two digits after the decimal. =

Use the diagram to the right to answer the following: a. The equilibrium value of real GDP is $ trillion. (Enter your response as a whole number.) b. The MPC is equal to (Enter your response rounded to two decimal places.) c. The multiplier is equal to (Enter your response rounded to one decimal place.) d. What is the value of unplanned changes in inventories when real GDP has each of the following values? (Enter your responses rounded to one decimal place and include a minus sign if necessary.) GDP $10 trillion $12 trillion $14 trillion Unplanned Inventories trillion trillion trillion C Aggregate Expenditure, AE ($, trillions) 24.0- 22.0 ≈ ≈ ¦ CO 20.0- 18.0- 16.0- 14.0- 12.0+ 10.0- 8.0- 6.0- 4.0- 2.0- 0.0- O. 13.6 12.0 10.4 0 45° -~ 2 4 AE 10:12:14 10 12 14 16 18 20 22 24 6 8 Real GDP, Y ($, trillions) G

3. Consumption function and non-income determinants The following graphs show an economy's initial position at point A along its consumption function (C). Suppose there is a decrease in the interest rate households pay for items bought on credit, such as cars or housing. On the graph, shift either the consumption curve or the initial point on the consumption function to show the impact of a decrease in the interest rate. (Note: In the scenario where the curve shifts, only shift the curve and do not adjust the position of the point.) RE AL CONSUMPTION (Billions of dollars) C REAL DISPOSABLE INCOME (Billions of dollars) Now suppose that disposable income increases. A On the following graph, shift either the consumption curve or the initial point on the consumption function to show the impact of an increase in disposable income. (Note: In the scenario where the curve shifts, only shift the curve and do not adjust the position of the point.)
