Shocks and rigidities as determinants of CEE labour markets’ performance

In this article, the impact of real wage, productivity, labour demand and supply shocks on eight Central and Eastern European (CEE) economies from 1996–2007 is analysed with a panel structural vector error correction model. A set of long‐run restrictions derived from the dynamic stochastic general equilibrium (DSGE) model is used to identify structural shocks, and fluctuations in foreign demand are controlled for. We find that the propagation of shocks on CEE labour markets resembles that found for OECD countries. Labour demand shocks emerge as the main determinant of employment and unemployment variability in the short‐to‐medium run, but wage rigidities were equally important for observed labour market performance, especially in Poland, Czech Republic and Lithuania. We associate these rigidities with collective bargaining, minimum wage, active labour market policies and employment protection legislation.     

HYSTERESIS HYPOTHESIS IN UNEMPLOYMENT AND LABOUR FORCE PARTICIPATION RATES: EVIDENCE FROM AUSTRALIAN STATES AND TERRITORIES *

This article simultaneously investigates the hysteresis hypothesis of unemployment and labour force participation using regional level data in Australia. The conventional univariate and panel unit root tests indicate that the hysteresis hypothesis cannot be rejected for most of the regions in Australia. To further confirm if the hysteresis finding in unemployment and labour force participation results from not considering structural breaks. We employ a panel stationarity test recently developed by Carrion‐i‐Silvestre et al. (2005 ), which considers multiple structural breaks and cross‐sectional dependence. The test results lend support for unemployment hysteresis and participation regime‐wise stationarity. Accordingly, the findings imply that a temporary shock may have permanent effects on the unemployment rate but not on labour force participation in Australia and thus call for policies aimed at improving the adjustment mechanism in unemployment.     

News shocks and labour market dynamics in matching models

We enrich a baseline real business cycle (RBC) model with search and matching frictions on the labour market and real frictions that are helpful in accounting for the response of macroeconomic aggregates to shocks. The analysis allows shocks to have an unanticipated and a news (i.e., anticipated) component. The Bayesian estimation of the model reveals that the model that includes news shocks on macroeconomic aggregates produces a remarkable fit of the data. News shocks in stationary and non‐stationary TFP, investment‐specific productivity and preference shocks significantly affect labour market variables and explain a sizeable fraction of macroeconomic fluctuations at medium‐ and long‐run horizons. Historically, news shocks have played a relevant role for output, but they have had a limited influence on unemployment.     

The European Commission’s new NAIRU: Does it deliver?

The non-accelerating inflation rate of unemployment (NAIRU) is a key component of potential output and as such critically affects output gap estimates. In May 2014, the European Commission changed its specification of the NAIRU for several countries and lowered its NAIRU estimates – in the case of Spain from 26.6% to 20.7% for 2015. To test the dependence of the new NAIRU on unemployment versus structural factors, we run counterfactual simulations applying 1SD shocks to actual unemployment and to the structural variable – real unit labour costs. We find that the NAIRU in its new specification is still largely determined by actual unemployment. This calls in question both the interpretation of potential output estimates as barriers to more vigorous inflation-stable economic activity and the accuracy of structural deficit figures.     

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.     

Cointegration and common trends on the West German labour market

In this paper we analyze the West German labour market by means of a cointegrated structural VAR model. We find sensible stable long-run relationships that are interpreted as a labour demand, a wage setting and a goods market equilibrium. In order to study the dynamic behaviour of the model we identify two common trends that push unemployment. We find that goods market shocks have only transitory impacts on unemployment. In the long run, it is almost equally determined by technology and labour supply factors. However, transitory shocks have major importance in the shorter run since adjustment processes are rather sluggish. First version received: Sept. 1998/Final version accepted: Feb. 2000     

The effects of shocks on the Austrian unemployment rate – a structural VAR approach

Assuming full hysteresis in the Austrian labour market, a simple macroeconomic framework is used to model the effect of four structural shocks, i.e. shocks to productivity, demand, wages and labour supply. By using SVAR analysis, we derive impulse-response functions that show the effects of these shocks on unemployment. What constitutes a distinctive feature of our study is the deliberate use of overidentifying restrictions, allowing for a likelihood ratio test. The objection to SVAR methodology, that it relies on arbitrary assumptions, can thus be overcome, as invalid sets of identifying restrictions are rejected.

The market for labour in Israel

Using annual observations for 1960–89, a complete economic model of the Israel labour market is estimated in which the demand for labour varies inversely with real wages, participation varies directly with the real wages and real wages are explained by a phillips curve in which the natural rate of unemployment is a variable. The model suggests that while wages are far from flexible, unemployment shocks die away fairly rapidly. we were unable to model the behaviour of public sector pay and employment.     

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.     

Uncertainty and employment dynamics in the euro area and the US

In this paper we investigate the local and foreign effects of uncertainty shocks on unemployment in two large economic regions, the United States (US) and the euro area (EA). We deploy a Bayesian Markov-switching structural vector autoregressive model identified via heteroscedasticity. Two alternative specifications are considered with the shocks of interest being labelled as “US (or EA) demand uncertainty” and “US (or EA) financial market uncertainty”. We reach similar conclusions using both specifications: (i) US shocks have an effect on both the local and foreign labour markets while euro area shocks are much less influential; (ii) the US labour market tends to react and absorb shocks more quickly than the labour market in the euro area does. As economic theory predicts, the reaction to uncertainty shocks points to possible market imperfections that are region specific.     

Unemployment dynamics with international capital mobility

We study the response of domestic unemployment rates to shocks in total factor productivity for economies with high capital mobility and low labour mobility. We show that high capital mobility amplifies the impact on the domestic unemployment rate of domestic fluctuations in total factor productivity, shortens the lag of the response to shocks and raises the variability of unemployment. But average unemployment is unaffected. Capital flows increase the riskiness of labour income and reduce the riskiness of capital income but do not reduce mean welfare.     

Growth,unemployment and labour market institutions: evidence from a cross-section of EU regions

The responsiveness of unemployment to growth is an issue of ongoing political and academic interest. Economic growth is supposed to be the key to increase labour demand and reduce unemployment. Departing from Okun's law, most research on the unemployment intensity of growth has focused on national disparities and the role of labour market institutions. Empirical evidence at the regional level is scarce. We investigate differences in regional labour market responsiveness and their potential determinants for a cross section of European regions. The data set covers the NUTS 2 regions in the EU15 for the period 1980 to 2002. Following a spatial modelling approach interaction among neighbouring labour markets is taken into account. Our findings point to substantial differences in labour market effects of output growth among European countries and regions. Both national labour market institutions and regional characteristics, such as structural change explain a significant part of these disparities.     

The Beveridge curve and labour market dynamics in Turkey

This article investigates the dynamics of unemployment and vacancy rates in Turkey during the period 1951 to 2008 by means of a Beveridge Curve (BC). The time-series analysis of unemployment and vacancies as well as two other relevant labour market variables, real wages and real labour productivity, strongly suggests inefficiency in the Turkish labour market. A stable long-run relationship between unemployment rate and vacancy rate is found for Turkey, that is, the existence of a negatively sloped BC is verified. The estimated Turkish BC reflects the structural problems and lack of flexibility in the labour market. The modified BC with real wages and labour productivity reveals that labour productivity has no significant effect on unemployment rate whereas wages have positive and significant effects on the same variable.     

Hysteresis versus natural rate in Taiwan's unemployment: Evidence from the educational attainment categories

This study examines the hysteresis hypothesis in unemployment for Taiwan's educational attainment categories. Both nonlinear dynamics and structural breaks in unemployment are applied in our examinations. The empirical results without structural changes show that the unemployment hysteresis hypothesis cannot be rejected in all educational attainment categories. After simultaneously incorporating nonlinear processes and smooth structural changes, we find that only the unemployment rate of junior college graduates reveals a mean reverting to the natural rate in the long-run, whereas all other series still support the hysteresis hypothesis. The results indicate that: i) the shocks have only temporary effects on the unemployment rate of the junior college graduates; ii) the labor or macroeconomic stabilization policies could have long lasting effects on unemployment rates of the other educational attainment categories; iii) the unemployment rates of low-skill labor are susceptible to the changes of economic or fiscal policies; and iv) practical and occupational training mechanisms should be implemented and strengthened in the higher education system to alleviate the increasingly serious problem of unemployment.     

HYSTERESIS IN UNEMPLOYMENT REVISITED: EVIDENCE FROM PANEL LM UNIT ROOT TESTS WITH HETEROGENEOUS STRUCTURAL BREAKS

This paper applies the panel LM unit root tests with heterogeneous structural breaks in level by Im  et al. ( Oxford Bulletin of Economics and Statistics , 67 (2005), pp. 393–419) to re-examine the validity of hysteresis in the unemployment rates of 19 OECD countries. Our empirical findings are favourable to the stationarity of the unemployment rates, i.e., the unemployment hysteresis hypothesis is strongly rejected. Our results suggest that shocks to unemployment rates are temporary and soon converge when we control for breaks. A major policy implication of the study is that a fiscal or monetary stabilization policy would not have permanent effects on the unemployment rates of the 19 OECD countries.     

Labour market reform and the macroeconomic efficiency of the labour market in Australia

This paper assesses the effects of a decade and a half of labourmarket reform in Australia on labour market flexibility at themacroeconomic level. Increased labour market flexibility isinterpreted as reduced structural unemployment and enhancedefficiency of matching. We use shifts in the Beveridge Curveas a measure of changes in labour market efficiency (followingSolow, R., What is labour-market flexibility? What is it goodfor?, Keynes Lecture, British Academy, London, December, 1997).Time series analysis of unemployment, vacancies and other relevantvariables strongly suggests that changes in the efficiency oflabour market matching over the period reflect the cyclicaleffects of hysteresis rather than the effects of labour marketreform.     

The Unemployment-Vacancy Relationship in Australia

One of the most important features of the Australian economy in the past two decades has been the structural deterioration of labour market performance, reflected in both an increase in the average rate of unemployment and an outward shift in the Beveridge Curve, which depicts the relationship between unemployment and vacancies. This article attempts to uncover some of the causes for this structural deterioration, in terms of the factors affecting the UVrelationship. We find that the Beveridge Curve shifted out around 1974, consistent with an increase in the equilibrium rate of unemployment which is generally agreed to have occurred around that time. Using gross labour market flow data, we also investigate the determinants of the equilibrium Beveridge Curve in the 1980s. We find that the Beveridge Curve shifted further outwards in the 1980s. The most important determinant of this shift was the decline in the search effectiveness of the unemployed, reflected in the increasing incidence of long-term unemployment. Partially offsetting this influence during this time were the declining labour force participation of men, and the very large increases in female employment.     

Hysteresis and sluggishness in Portuguese unemployment, 1977–88

The phenomenon of unemployment persistence led to the development of alternative theories of unemployment. Among these the ‘hysteresis’ concept by Blanchard and Summers (1987) received a wide interest. Based on this notion we developed a generalized model that nests Blanchards and Summers' theory. Using this framework we conducted an empirical investigation for the Portuguese labour market (1977–88). The results obtained point towards the existence of labour demand sluggishness, wage inertia and unemployment hysteresis. The model also suggests the existence of a rather inelastic labour demand curve.     

Looking for the workforce: the elderly,discouraged workers,minorities, and students in the Baltic labour markets

This paper looks at the evolution of the labour markets in Estonia, Latvia, and Lithuania since the beginning of transition until 2003, with a particular focus on labour force participation. How did labour supply in the Baltic countries respond to changes in minimum wages, unemployment benefits and retirement regulation? Do the marked differences in labour market policies between the countries result in different patterns of participation? What are the obstacles to and driving forces of participation? We find that relative contribution of participation and demographic trends to the dynamics of the labour force varied substantially both over the years and across the three countries. Participation, in turn, has been shaped by sometimes complicated interactions between schooling decisions of the youth, retirement, policy changes, and external shocks. Resulting differences in trends and patterns are quite substantial, indicating that there is a room for increasing participation in each of the countries. Panel data analysis of determinants of participation and discouragement based on labour force survey data suggests that increasing after-tax real minimum wage has significant positive effects on participation and reduces discouragement in Lithuania. In Estonia, by contrast, a positive effect of minimum wage on participation is found only for teenagers of both genders and for young males. We do not find any evidence that partner’s wage has a negative effect on participation. Ethnic minorities, especially females, in all three Baltic countries are less likely to be in the labour force, other things equal.
