Final answer:
The Taylor Rule predicts the target interest rate for central banks based on inflation and unemployment rates. The formula for the Taylor Rule is target interest rate = equilibrium interest rate + 0.5 * (actual inflation rate - target inflation rate) + 0.5 * (actual unemployment rate - full-employment unemployment rate). Plugging in the given values, the Taylor Rule predicts that the Fed's target interest rate in 1980 would be the equilibrium interest rate plus 6.2%.
Step-by-step explanation:
The Taylor Rule is a monetary policy guideline that provides a suggested target interest rate for central banks based on inflation and unemployment rates. It is named after economist John Taylor.
The formula for the Taylor Rule is: target interest rate = equilibrium interest rate + 0.5 * (actual inflation rate - target inflation rate) + 0.5 * (actual unemployment rate - full-employment unemployment rate)
Using the given information, the target inflation rate is 2.5% and the full-employment unemployment rate is 5%. The actual inflation rate in 1980 was 12.5% and the actual unemployment rate was 7.4%.
Plugging these values into the Taylor Rule formula, we get: target interest rate = equilibrium interest rate + 0.5 * (12.5% - 2.5%) + 0.5 * (7.4% - 5%) = equilibrium interest rate + 5% + 1.2%
Therefore, the Taylor Rule predicts that the Fed's target interest rate in 1980 would be the equilibrium interest rate plus 6.2%.
