Step 2: The Effect of Saving on Total Expenditures 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. Before Saving Decrease $280 million $200 million $250 million $500 million $300 million Consumption (C) Investment (I) Government Purchases (G) Exports (EX) Imports (IM) As a result of the decrease in saving, total expenditures will After Saving Decrease $320 million million million $500 million $300 million
