Purchasing Power Parity Is An Essay

The policy prescription for the classical economist will not be to adjust inflation in order to deal with unemployment. In the short run, the classical economist may view that the Phillips Curve holds, but only until the point where workers become informed, at which point they would demand an increase in real wages.

Keynesians believe that the Phillips Curve does hold and therefore government can trade inflation for unemployment. Setting interest rates low for high inflation will create economic expansion which in turn will reduce unemployment. The Keynesian...
