Short Answer 10 points each #1: How is the Quantity Theory of Money related to the Natural Rate Hypothesis? You are given the following information about an economy: 1) at full employment, the unemployment rate is 5% and real output is $500 billion; and 2) the following table applies: Inflation rate: 5% 2.5% 1.5% Unemployment rate: 4% 5% 6% Real output: $550 billion $500 billion $450 billion Assuming the price level in Period 0 was 100, graphically show the economy s long-run and short-run Phillips Curve and corresponding long-run and short-run aggregate supply curves in Period 1. Use the AS-AD Model to graphically display a recession and show how an increase in government expenditures is one way to return the economy to a full-employment equilibrium. Page 5 of 5
