Hysteresis and Business Cycles


Book Description

Traditionally, economic growth and business cycles have been treated independently. However, the dependence of GDP levels on its history of shocks, what economists refer to as “hysteresis,” argues for unifying the analysis of growth and cycles. In this paper, we review the recent empirical and theoretical literature that motivate this paradigm shift. The renewed interest in hysteresis has been sparked by the persistence of the Global Financial Crisis and fears of a slow recovery from the Covid-19 crisis. The findings of the recent literature have far-reaching conceptual and policy implications. In recessions, monetary and fiscal policies need to be more active to avoid the permanent scars of a downturn. And in good times, running a high-pressure economy could have permanent positive effects.




The Natural Rate of Unemployment


Book Description

For 25 years, theory about the causes of, and possible solutions to, the problem of unemployment has been dominated by Phelps' and Friedman's natural rate of unemployment hypothesis. This postulates that the equilibrium rate of unemployment consistent with steady inflation is determined by structural variables: sustainable reductions in unemployment can be achieved only by measures to change underlying microeconomic structures, such as benefit and pay bargaining systems. Belief in the hypothesis has faltered since the 1980s, the hypothesis being unable to explain the dramatic upward shifts in European unemployment rates. These essays reflect upon the fundamental structures underlying the hypothesis, assess the related evidence, and look forwards, suggesting possible modifications. In contrast to the single rate postulated by the natural rate hypothesis, several of the contributors propose that there are ranges of unemployment rates consistent with steady inflation.










A History of Macroeconomics from Keynes to Lucas and Beyond


Book Description

This book retraces the history of macroeconomics from Keynes's General Theory to the present. Central to it is the contrast between a Keynesian era and a Lucasian - or dynamic stochastic general equilibrium (DSGE) - era, each ruled by distinct methodological standards. In the Keynesian era, the book studies the following theories: Keynesian macroeconomics, monetarism, disequilibrium macro (Patinkin, Leijongufvud, and Clower) non-Walrasian equilibrium models, and first-generation new Keynesian models. Three stages are identified in the DSGE era: new classical macro (Lucas), RBC modelling, and second-generation new Keynesian modeling. The book also examines a few selected works aimed at presenting alternatives to Lucasian macro. While not eschewing analytical content, Michel De Vroey focuses on substantive assessments, and the models studied are presented in a pedagogical and vivid yet critical way.

Unemployment in Latin America and the Caribbean


Book Description

JEL Cl This study constructs a new data set on unemployment rates in Latin America and the Caribbean and then explores the determinants of unemployment. We compare different countries, finding that unemployment is influenced by the size of the rural population and that the effects of government regulations are generally weak. We also examine large, persistent increases in unemployment over time, finding that they are caused by contractions in aggregate demand. These demand contractions result from either disinflationary monetary policy or the defense of an exchange - rate peg in the face of capital flight. Our evidence supports hysteresis theories in which short - run changes in unemployment influence the natural rate.




Explaining Unemployment in Spain


Book Description

Spain has the most serious and persistent unemployment problem in Europe, with an unemployment rate that reached 24.6 percent in early 1994. This paper explores the characteristics of this unemployment problem, its causes, and provides a brief discussion of recent labor market reform measures and their likely Impact. A demographic shift in recent years has produced a large rise in female labor force participation and a decrease in agricultural jobs to which the economy has been unable to adjust. The effects of generous unemployment benefits and the large underground economy may explain 6–12 percentage points of the resulting unemployment, but the remainder must be explained by failures and rigidities in the labor market. The paper presents econometric evidence that unemployment displays hysteresis, and that wages are not responsive to changes in the unemployment rate. This evidence supports the claim that insider-outsider factors and rigidities in the legal structure of the labor market are responsible for much of the high unemployment rate. Recent reforms have improved the functioning of the labor market, but they are unlikely to be sufficient to reduce unemployment to single digit rates without further action.




Rapid Growth and Relative Decline


Book Description

Do high rates of economic growth create conditions favourable to their own maintenance? Or can a period of high growth 'sow the seeds of its own destruction'? This book addresses these questions by conceiving growth and structural change as path dependent processes. Methodological, theoretical and empirical insights are combined in an extended model of cumulative causation, which shows how endogenously induced technological and institutional changes may cause the dynamics of a period of high growth to break down. This casts new light on the debate over Britain's economic decline.
