Classical Macroeconomics
Money and the Price Level
Classical macroeconomics asserted that monetary policy affected only the aggregate price level, not aggregate output, and that the short run was unimportant.
By the 1930s, measurement of business cycles was a well established subject, but there was no widely accepted theory of business cycles.

Inflation and the Natural Rate of UnemploymentThe natural rate of unemployment is also the non-accelerating-inflation rate of unemployment, or NAIRU.
inflation eventually gets built into expectations, so any attempt to keep the unemployment rate below the natural rat will lead to an ever-rising inflation rate.

Rational Expectations, Real Business Cycles, andNew Classical MacroeconomicsNew classical macroeconomics is an approach to the business cycle that returns to the classical view that shifts in the aggregate demand curve affect only the aggregate price level, not aggregate output.
Rational expectations is the view that individuals and firms make decisions optimally, using all available information.
