Testing for hysteresis in unemployment an unobserved components approach

We suggest a new test for hysteresis in unemployment based on an unobserved components model. Observed unemployment rates are decomposed into a natural rate component and a cyclical component. The impact of lagged cyclical shocks on the current natural component is the measure of hysteresis. To identify the two components of unemployment, we assume that the cyclical compoentn is correlated with capacity utilization. The model is applied to U.S. and German data. We find no evidence of hysteresis in U.S. data. German unemployment rates exhibit substantial hysteresis. A shock of 1.0 percent to the current cyclical component permanently increases future German natural rates by about 0.5 percent. For both countries, natural rate shocks turn out to be an important impulse mechanism to explain movements in observed unemployment rates.     

The Beveridge curve in Europe: new evidence using national and regional data

The Beveridge curve depicts the empirical negative relationship between job vacancy rate and unemployment rate, and reflects the efficiency of the job matching process. Movements along a fixed downward sloping Beveridge curve are associated with cyclical shocks, while shifts of the curve arise from structural factors that alter the matching efficiency between job vacancies and unemployed workers. National and regional data on job vacancies and unemployment are combined to estimate the Beveridge curves of five European countries and their regions, focusing on the period 1975 to 2004. I also analyse whether shifts in European Beveridge curves are due to changes in the composition of the unemployed pool, labour market rigidities or cyclical and structural shocks. The empirical evidence suggests that changes in labour market rigidities, long term unemployment, as well as cyclical shocks are responsible for outward shifts in European Beveridge curves. I also find evidence of nonlinearities in the relation between unemployment and labour market institutions.     

Keynes,investment, unemployment and expectations

In Keynes’ General Theory, investment determines effective demand, which determines unemployment and the labour market plays a negligible role. In New Keynesian models, labour market institutions determine the natural rate of unemployment and the speed at which unemployment adjusts to it. Investment is mostly ignored as a key variable behind the problem of high unemployment, despite a strong empirical association between investment and unemployment. We discuss the evolution of the ‘Keynesian’ model, and how in the process of domesticating the General Theory, the central relationship between unemployment and investment and the role of the state of confidence was bred out of the model. We then present some evidence of the centrality of investment and expectations to the long‐term evolution of unemployment in OECD countries. We also argue that recent results in finance, which find that individuals do not behave rationally and, moreover, that there may be no basis for rational calculation, provides support for Keynes’s notion that animal spirits play a central role in investment.     

Pigou on business cycles and unemployment: an anti-gold-standard view

Abstract

This note examines A. C. Pigou's views on the practical issue of high unemployment in the 1920s. In his Industrial Fluctuations, Pigou emphasized that the monetary aspect of business cycles was much more important to fluctuations in unemployment than wage adjustment. In a journal article, however, he stated that major part of the high unemployment should be attributed to the failure of money wage adjustment. I argue that, on balance, Pigou attached greater importance to monetary problems than to the wage rigidity.     

Deriving natural rates of unemployment for sub-national regions: the case of Canadian provinces

In order to pursue informed stabilization policies, it is vital for policy-markers to have estimates of how much of the total unemployment rate can be classified as cyclical rather than natural unemployment. This paper describes a method for generating regional natural-rate estimates and applies this method to the case of Canadian provinces. Results indicate that unemployment insurance generosity and relative minimum wages play an important role in determining natural unemployment rates in Canadian provinces. One of the enduring characteristics of the Canadian labour market has been substantial and peresistent unemployment rate disparities across provinces. The results of this study indicate that these disparities are primarily explained by differences in provincial values of structural variables such as unemployment generosity and by differences in provincial sensitivities to these structural variables. A furher result is that variation in cyclical unemployment rates is substantially less in the traditionally high unemployment region of Atlantic Canada than it is in the traditionally low unemployment province of Ontario. This result implies that the most appropriate policies to reduce unemployment in Atlantic Canada are not regionally-applied expenditure policies but rather policies designed to reduce structural distortions in the provincial labour markets.     

Image and Reality in Economic Development

Since the financial meltdown of 2007, unemployment has consistently been above 6.0 percent. On one level, long-term unemployment can be accounted for by structural changes. But, on another level, the problem of long-term unemployment is really no more complicated than the absence of effective demand. This study looks at the demographics of the long-term unemployed for the years 2007-2010, and compares them to the years 1991-1994 to see what changes have occurred specifically among the long-term unemployed. The data shows that, in terms of structural changes, the 1991-1994 and 2007-2010 periods were not much different. Rather, the nature of this recession resulted in an altered composition of the long-term unemployed. Because long-term unemployment in this recession is a function of a particularly deep recession, a new approach is needed. Based on the data, this study argues for a wage policy that would allow for people to increase their effective demand for goods and services.

Upper Secondary School Completion and the Business Cycle

Previous evidence suggests that enrollment in post‐compulsory education increases (decreases) in cyclical downturns (upturns). However, little evidence exists on whether enrollment is successfully transformed into completed education. This paper adds to the literature by analyzing the relationship between completion of upper secondary education and regional unemployment using Norwegian regional panel data on students graduating from compulsory school between 1981 and 2004. We find robust evidence that completion rates are countercyclical. Our results suggest that poor labor‐market conditions when starting upper secondary education have a lasting effect and motivate students to stay in school and graduate.     

Wage,productivity and unemployment: microeconomics theory and macroeconomics data

We confront microeconomics theory with macroeconomics data. Unemployment results from two main micro-level decisions of workers and firms. Most of the efficiency wage and bargaining theories predict that over the business cycle, unemployment falls below its natural rate when the worker’s real wage exceeds the reservation wage. However, these theories have weak empirical support. Firm’s decision predicts that when the worker’s real wage exceeds the marginal product of labour (MPL), unemployment increases above its natural rate. Accounting for this microeconomic decision helps explain almost all the fluctuations of US unemployment.     

Vicious and virtuous circles — The political economy of unemployment in interwar UK and USA

This paper develops a political economy model of multiple unemployment equilibria to provide a theory of an endogenous natural rate of unemployment for the UK and the US interwar period. The theory here sees the natural rate and the associated path of unemployment as a reaction to mainly demand shocks and the institutional structure of the economy. The channel through which these two forces feed on each other is a political economy process whereby voters with limited information on the natural rate react to shocks by demanding more or less social protection. The reduced form results confirm a pattern of unemployment behaviour in which unemployment moves between high and low equilibria in response to shocks.     

Estimating Europe’s natural rates

This article estimates potential output, the natural rate of unemployment, and the core inflation rate using aggregated euro area data. The empirical model consists of a Phillips curve linking inflation to unemployment. An Okun-type relationship is used to link the output gap to cyclical unemployment. The model further accounts for new developments in unobserved component models by allowing (i) for correlation between shocks to the natural rates and the corresponding gaps and (ii) structural breaks in the drift of potential output and the natural rate of unemployment.     

Layoffs,recalls and unemployment duration: evidence from Sweden

The question addressed in this paper is whether the possibility of exit from unemployment to the previous employer affects the duration of unemployment spells in Sweden. The empirical analysis is performed using an employee–employer dataset that includes a number of enterprise characteristics and provides information on individual tenure. The econometric approach employs estimation of a competing risk duration model to distinguish between exits to the previous employer and exits to a new job. The findings suggest that greater tenure raises the risk of transition to the previous employer, while high education levels increase the risk of obtaining a new job. Moreover, the impact of benefit exhaustion is observed only for transitions to new employment.

Earnings inequality and unemployment in South Africa

Unemployment and earnings inequality have moved together remarkably closely in South Africa in recent years. This article explores the relationship between unemployment and earnings inequality in South Africa, investigating the extent to which changes in unemployment can account for changes in earnings inequality. Static and dynamic decompositions of earnings inequality by employment status reveal the centrality of unemployment in accounting for the both level and trend of earnings inequality. The distribution of employment in the formal and informal sectors is found to be of lesser importance in explaining earnings inequality, as is wage dispersion within each of these categories. The findings point to the central importance of reducing unemployment in South Africa if the extremely high levels of inequality are to be reduced.     

Do Government Purchases Affect Unemployment?

We estimate the effect of government purchases on unemployment in 20 OECD countries, for the period 1980–2007. An increase in government purchases, equal to 1 percent of GDP, is found to reduce unemployment by about 0.3 percentage points in the same year. The effect is greater and more persistent under less “employment‐friendly” labour‐market institutions, and it is greater and more persistent under a fixed exchange rate regime than under a floating regime. The effect is also greater in downturns than in booms. The effect on unemployment reflects a corresponding positive effect of increased government purchases on the employment‐to‐population rate.     

Women's unemployment during transition Evidence from Czech and Slovak micro-data

We analyse women’s weekly probabilities of leaving unemployment in the Czech and Slovak Republics (CR and SR) in order to investigate three questions: 1) Why are unemployment rates much lower in the CR than the SR?; 2) Does the unemployment compensation scheme (UCS) substantially lengthen unemploy-mentspells?; and 3) Why are women’s unemployment rates higher than men’s? We find that differences in the behaviour of the individuals, employers and institutions in the SR and CR (as measured by differences in coefficients) play a larger role in determining the CR’s shorter female unemployment spells than do differences in measured demand and demographic variables. The UCS has only a moderate effect on duration and its impact is greater in the CR. The differences between men’s and women’s spells (in each republic) are explained more by differences in coefficients than by differences in observed characteristics.

Potential duration of unemployment benefits and labor market outcomes for older workers with health impairments in Germany

This research note estimates the causal effects of a cut in the potential duration of regular unemployment benefits for older workers in Germany on the labor market outcomes of individuals with health impairments. The analyzed reform is a natural experiment that allows a difference-in-differences strategy with treatment intensity. The results provide evidence for a significant decrease in the number of days in regular unemployment benefits and an increase in the number of days in employment. However, the results also suggest a significant increase in the number of days in unemployment (social) assistance, which are granted upon exhaustion of regular unemployment benefits.     

On Keynes on inflation and unemployment

Keynes tends to be represented as someone who thought that alleviating unemployment was more important than any other consideration. Interestingly it seems that this was not always the case; he did not recommend employment creation under all conditions of excess labour supply. The great inflation of World War I and its aftermath left an indelible impression on him, and this mitigated his position on the importance of high levels of employment. In 1920 he recommended that inflation in the UK be controlled even if some unemployment would result, and there is at least some hint in his work that the relative importance to him of inflation and unemployment did not vary much over the remainder of his life.
