5 SRASlow oil prices SRASWelfare Reform
Lower oil prices reduces the cost of production shifting the SRAS to the left. This increases real GDP and lowers prices. 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. If the decrease in oil prices is permanent, the LRAS will shift to the right. 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. Because the changes in welfare are permanent, the LRAS will shift to the right and shifting the institutional PPF outward.

For instance, converting nominal 2012 income to 2010 prices would be done with the formula. The price index using 2010 as the base year is computed by taking the basket of goods actually consumed in 2010 and computing what that exact basket of goods would cost if purchased at 2006 and 2012 prices. For instance the 2010 price level using 2006 as the base year is computed with:
