5 Dollars Saved or Invested Interest Rate Investment Savings All Other Goods Real GDP Good X Price Level LRAS Natural GDP SRAS AD Institutional PPF Physical PPF SRAS low oil prices 1.Lower oil prices reduces the cost of production shifting the SRAS to the left. This increases real GDP and lowers prices. 2.The increase in real GDP will cause a rightward shift in the savings curve. The shift will be larger if the drop in oil prices is temporary and smaller if the drop in prices is considered permanent. This will cause a decrease in interest rates and an increase in investment. 3.If the decrease in oil prices is permanent, the LRAS will shift to the right. 4.Welfare reform forces people off of government assistance and into the civilian labor force. This increases the supply of labor, lowers wage rates, and further shifts the SRAS to the right, increasing real GDP, and lowering prices. 5.Because the changes in welfare are permanent, the LRAS will shift to the right and shifting the institutional PPF outward.

For instance the 2010 price level using 2006 as the base year is computed with: Nominal income is converted to real income by taking nominal income in a given year and dividing by the price index for that year and the chosen base year. For instance, converting nominal 2012 income to 2010 prices would be done with the formula. Real Income Base Year Income $ 6,600 $ 5,532 $ 4, $ 6,815 $ 5,700 $ 4, $ 6,511 $ 5,427 $ 4,380 Price Index Base Year Price Index
