Chapter 14: Stabilization Policy Policy Activism Economy is not self-correcting We need to implement stabilization policy to correct business cycles Use fiscal and monetary policy to prevent recession and control inflation Example of active monetary policy: M2 Growth = 3% + (u – 6%) whenever correction is required Policy Passivism Government budgetary actions and stabilization attempts are the source of economic instability Government can make matters worse as it did in the Great Depression by implementing concretionary policies of tax and interest rate increases! Example of passive monetary policy: M2 Growth = 3% annually Policy Lags Inside lags: time between a shock to the economy and policy action responding to that shock Outside lags: time between implementation of a policy action and its effect on the economy Policy Lags: Inside Lags Recognition lag: The time it takes for policy makers to recognize the existence of a boom or slump Formulation lag: The time it takes to design policy measures to correct a boom or slump Policy Limitations: Outside Lags Implementation lag: The time it takes to put the desired policy measures into effect in correcting a boom or slump Response lag: The time it takes for the economy to adjust to new conditions after policy measures are implemented Duration of Lags Monetary policy requires shorter formulation and implementation lags as the FED decides how to correct a boom or slump Fiscal policy requires longer formulation and implementation lags as a tax or spending policy must be approved by the Congress and implemented by federal agencies Automatic Stabilization Boom: greater employment, inflation, and nominal wage will move workers into higher tax brackets Paying more taxes reduce disposable income and consumption spending, slowing the economy Slump: greater unemployment and lower inflation and nominal wage will move workers into lower tax brackets Paying less taxes increases disposable income and consumption spending, stimulating the economy Forecasting: Leading Indicators 10 11 Manufacturing production workweek Weekly unemployment claims New orders for consumer goods and materials Vendor performance Orders for plants and equipment Change in manufactures’ unfilled orders New building permits issued Change in sensitive materials prices Index of stock prices Real money supply (M2) Index of consumer expectations Macroeconomic Forecasting Economists apply empirical models to macro data to forecast conditions While minimizing the forecast error, there still are discrepancies between actual and predicted values because, despite sophistication, models can’t account for all possible effects Forecasting Errors Forecasting Errors Generating 6-months forecasts, economists could not correctly predict the rapid – Rise in unemployment rate from 1981.2 to 1982.4 – Fall in unemployment rate from 1982.4 to 1984.4 Formation of Expectations Adaptive expectations: expectations are formed using past information on the indicator being considered Rational expectations: expectations are formed using past and present information on all possible variables that affect the indicator being considered Robert Lucas’ Critique Policy makers must take into account how people’s expectations respond to policy changes Traditional methods of policy evaluation not adequately take into account the policy effects on people’s expectations Sacrifice Ratio & Expectations Sacrifice Ratio: the percentage of real GDP that must be given up to lower inflation by percent Policy makers prefer to live with inflation since they find the Sacrifice Ratio to be too high for the public Rational-expectations advocates assert that Sacrifice Ratio estimation is subject to Lucas critique; it assumes expectations are formed adaptively rather than rationally Distrust of Policy Makers Policy can be implemented to manipulate the economy for political purposes (e.g., the short-run Phillips Curve) Time inconsistency of discretionary policy: promise one policy, but implement another policy; e.g., promise an investment tax credit, but after factories are built increase corporate income tax rate Political Business Cycle Business cycle induced by policy makers: – slow the economy in the first two years of a political administration – stimulate the economy in the last two years to cause a boom just in time for the next election Data partly supports this idea for the Republican presidents Economic Growth and Politics Rules of Monetary Policy Respond to policy shocks (e.g., energy crisis) Target GDP growth to achieve natural unemployment rate Target inflation to keep it low Inflation & Central Bank Rules of Fiscal Policy Budgetary balance or surplus Deficit spending to cause growth to shift the burden to the next generation through debt Tax smoothing to reduce distortions by keeping rates relatively stable
