This document discusses inflation, unemployment, and the Phillips curve relationship between the two. It defines inflation as a rise in the general price level and identifies different types of inflation including demand-pull, cost-push, and stagflation. Causes of inflation like increases in costs, money supply, and aggregate demand are explained. Methods for controlling inflation including monetary, fiscal, and other supply-side policies are outlined. The Phillips curve relationship is introduced as showing an inverse relationship between inflation and unemployment, though this broke down in the 1970s. Factors like inflation expectations, supply capacity and the non-accelerating inflation rate of unemployment (NAIRU) are discussed in relation to the Phillips curve.
