Supply side policies can be shown by attributing periods of stagflation (high prices and low level of output) to upward shifts of aggregate supply. The recommended policy would then not be an increased aggregate demand which adds to inflation, but instead a shift in aggregate supply downward by cutting costs of production.
During the 1980's, the American administration has attempted to control the economy by paying more attention to the supply side of the economy. Specifically, costs of production are affected by regulations, restrictions and subsidies enacted by government bodies. |
