Equilibrium Unemployment And Optimal Monetary Policy

I introduce unemployment into the New Keynesian model by assuming search and matching frictions in the labor market, and analyze the implications for optimal monetary policy. In this framework, firms can adjust both their number of workers and hours per worker. Social efficiency requires eliminating inflation, closing the output gap (equivalently, setting hours at their efficient level), as well as preventing deviations of employment from its efficient path. I show that, provided the economy's steady state is efficient, if wages follow the Nash bargaining rule the central bank can achieve the efficient allocation. If wages are rigid, then the central bank faces a trade-off among its stabilization objectives. Following e.g. a negative productivity shock, the central bank must temporarily concede an increase in inflation, a drop in the output gap and a fall in employment below its efficient path.

Recent theoretical and empirical work has cast doubt on the hypotheses of a linear Phillips curve and a symmetric quadratic loss function underlying traditional thinking on monetary policy. This paper analyzes the Barro-Gordon optimal monetary policy problem under alternative loss functions—including an asymmetric loss function corresponding to the “opportunistic approach” to disinflation—when the Phillips curve is convex. Numerical simulations are used to compare the implications of the alternative loss functions for equilibrium levels of inflation and unemployment. For parameter estimates relevant to the United States, the symmetric loss function dominates the asymmetric alternative.

This book pulls together papers presented at a conference in honour of the 1981 Nobel Prize Winner for Economic Science, the late James Tobin. Among the contributors are Olivier Blanchard, Edmund Phelps, Charles Goodhart and Marco Buti. One of the main aims of the conference was to discuss what potential role monetary policy has on economic activity and unemployment reduction in three key currency zones - the United States, European Union and Japan.

Dissatisfied with the explanations of the business cycle provided by the Keynesian, monetarist, New Keynesian, and real business cycle schools, Edmund Phelps has developed from various existing strands-some modern and some classical--a radically different theory to account for the long periods of unemployment that have dogged the economies of the United States and Western Europe since the early 1970s. Phelps sees secular shifts and long swings of the unemployment rate as structural in nature. That is, they are typically the result of movements in the natural rate of unemployment (to which the equilibrium path is always tending) rather than of long-persisting deviations around a natural rate itself impervious to changing structure. What has been lacking is a "structuralist" theory of how the natural rate is disturbed by real demand and supply shocks, foreign and domestic, and the adjustments they set in motion. To study the determination of the natural rate path, Phelps constructs three stylized general equilibrium models, each one built around a distinct kind of asset in which firms invest and which is important for the hiring decision. An element of these models is the modern economics of the labor market whereby firms, in seeking to dampen their employees' propensities to quit and shirk, drive wages above market-clearing levels-the phenomenon of the "incentive wage"--and so generate involuntary unemployment in labor-market equilibrium. Another element is the capital market, where interest rates are disturbed by demand and supply shocks such as shifts in profitability, thrift, productivity, and the rate of technical progress and population increase. A general-equilibrium analysis shows how various real shocks, operating through interest rates upon the demand for employees and through the propensity to quit and shirk upon the incentive wage, act upon the natural rate (and thus equilibrium path). In an econometric and historical section, the new theory of economic activity is submitted to certain empirical tests against global postwar data. In the final section the author draws from the theory some suggestions for government policy measures that would best serve to combat structural slumps.

The recent global financial crisis illustrates that financial frictions are a significant source of volatility in the economy. This paper investigates monetary policy stabilization in an environment where financial frictions are a relevant source of macroeconomic fluctuation. We derive a measure of output gap that accounts for frictions in financial market. Furthermore we illustrate that, in the presence of financial frictions, a benevolent central bank faces a substantial trade-off between nominal and real stabilization; optimal monetary policy significantly reduces fluctuations in price and wage inflations but fails to alleviate the output gap volatility. This suggests a role for macroprudential policies.

Expectations, Employment and Prices brings Keynesian economics into the 21st century by providing a new paradigm that explains how high unemployment could potentially persist forever without a little help from the government. The book fills in logical gaps that were missing from Keynes' General Theory of Employment Interest and Money by reconciling some of its key ideas with modern economic theory. Central bankers throughout the world are talking now about developing a second instrument of monetary policy in addition to controlling the interest rate. Roger Farmer directly addresses this issue and offers new creative monetary policy proposals and suggestions for the design of new financial institutions for the 21st century.

The classic introduction to the New Keynesian economic model This revised second edition of Monetary Policy, Inflation, and the Business Cycle provides a rigorous graduate-level introduction to the New Keynesian framework and its applications to monetary policy. The New Keynesian framework is the workhorse for the analysis of monetary policy and its implications for inflation, economic fluctuations, and welfare. A backbone of the new generation of medium-scale models under development at major central banks and international policy institutions, the framework provides the theoretical underpinnings for the price stability–oriented strategies adopted by most central banks in the industrialized world. Using a canonical version of the New Keynesian model as a reference, Jordi Galí explores various issues pertaining to monetary policy's design, including optimal monetary policy and the desirability of simple policy rules. He analyzes several extensions of the baseline model, allowing for cost-push shocks, nominal wage rigidities, and open economy factors. In each case, the effects on monetary policy are addressed, with emphasis on the desirability of inflation-targeting policies. New material includes the zero lower bound on nominal interest rates and an analysis of unemployment’s significance for monetary policy.
