Unemployment insurance in a sticky-price model with worker moral hazard

This paper studies the role of unemployment insurance in a sticky-price model that features an efficiency-wage view of the labor market based on unobservable effort. The risk-sharing mechanism central to the model permits, but does not force, agents to be fully insured. Structural parameters are estimated using a maximum-likelihood procedure on US data. Formal hypothesis tests reveal that the data favor a model in which agents only partially insure each other against employment risk. The results also show that limited risk sharing helps the model capture many salient properties of the business cycle that a restricted version with full insurance fails to explain.     

A monetary business cycle model with unemployment

To reproduce key features of the post-war U.S. data, most monetary business cycle models must assume there are high price markups and that agents have high labour supply elasticities despite the existence of contradictory microeconomic evidence. This paper eliminates the need for these assumptions by introducing imperfectly observed effort into a limited participation model. The estimated model is better able to capture the sluggish price response to a monetary policy shock than the standard model, and is consistent with evidence regarding the qualitative responses of the U.S. economy to technology shocks, fiscal policy shocks and monetary policy shocks.     

Employment relations and labour market indicators in ten industrialized market economies: Comparative statistics

The acceleration of the internationalisation of business and the division of labour has been led by improvements in technologies and communications, decreased barriers to trade, increased competition and the growth of multinational enterprises (MNEs). Employers, government organizations and unions, practitioners and academics are increasingly concerned with locating comparable statistics. This article reviews employment relations and labour market data for ten major industrialized market economies (IMEs) and discusses some of the challenges in the measurement and interpretation of such data. For a fuller discussion of such data, and of the ten IME, see Greg J. Bamber and Russell D. Lansbury (eds) International and Comparative Employment Relations 3rd edn, to be published by Sage, London, and Allen & Unwin, Sydney, in mid-1998.     

Should I stay or should I go? The effect of gender,education and unemployment on labour market transitions

This paper re-examines the turnover behaviour of men and women using panel data from six European countries. It makes a distinction between job-to-job (JJ) and job-to-non-employment (JNE) transitions, and explores the role that education and unemployment play in gender differences regarding these mobility patterns. Low educated women have lower JJ transition probabilities but are more likely to exit to non-employment compared to the other groups, high-educated women and men of all educational levels. Furthermore, unemployment reduces the JJ turnover of male and female workers of all educational levels. There is a pro-cyclical response in the JNE transitions of the less-educated males and a counter-cyclical response in the JNE transitions of the less-educated females. Finally, there are remarkable similarities in labour market mobility across countries, although there are various institutional and other labour market differences.     

Are unemployment rates in OECD countries stationary? Evidence from univariate and panel unit root tests

This paper revisits the dynamics of unemployment rate for 29 OECD countries over the period of 1980–2013. Numerous empirical studies of the dynamics of unemployment rate are carried out within a linear framework. However, unemployment rate can show nonlinear behaviour as a result of business cycles or some idiosyncratic factors specific to labour market (Cancelo, 2007). Thus, as a testing strategy, we first perform Harvey, Leybourne, and Xiao (2008) linearity unit root test and then apply the newly ESTAR nonlinear unit root test suggested by Kruse (2011). This test has higher power than conventional unit root tests when time series exhibits nonlinear behaviour. Our empirical findings provide significant evidence in favour of unemployment rate stationarity for 25 countries. For robustness purpose, we have also used panel unit root tests without and with structural breaks. The empirical results show that unemployment hysteresis hypothesis is strongly rejected, when taking into account the cross-sectional and structural break assumptions. Thus, unemployment rate is expected to return back to their natural levels without executing any costly macroeconomic labour market policies by the OECD’s governments.     

The joint impact of labour policies and the “Great Recession” on unemployment in Europe

The paper consists of an empirical analysis of the separate as well as joint impacts on total and youth unemployment of indicators of labour market policies on the one hand, and the financial crisis associated with the “Great Recession” on the other. In particular, we investigate labour market data in the past two decades for the Enlarged Europe and adopt a variable accounting for the idiosyncratic severity shock of the crisis. This time-varying and country-specific crisis variable enables us to test empirically and in a novel way the joint impact of labour market policies and the economic crisis on labour market dynamics even when accounting for common macro shocks.

Does pay affect productivity or react to it?: Examination of U.S. manufacturing

There may be a bi-directional relationship between wages and labor productivity. According to conventional theory, employers reward improvements in productivity by raising pay. It also has been argued that wage increases can provide an incentive to improve productivity. This study applies a technique by Geweke to identify the feedback between pay and productivity in U.S. manufacturing. For the 1949–1998 period, measures of directional feedback indicate that both “pay as reward” and “pay as incentive” behaviors have occurred, but the results vary across manufacturing subsectors.     

Sticky prices, fair wages, and the co-movements of unemployment and labor productivity growth

This paper studies the co-movements of unemployment and labor productivity growth for the U.S. economy. Measures of co-movements in the frequency domain indicate that co-movements between variables differ strongly according to the frequency. First, long-term and business cycle co-movements are larger than short-term co-movements. Second, co-movements are negative in the short and long run, but positive over the business cycle. A New Keynesian model that combines nominal rigidity on the goods market (sticky prices) and real rigidity on the labor market (fair wages) is shown to be quantitatively consistent with the observed co-movements both in the long term and over the business cycle. However, the model fails to explain the short-term co-movements.     

Unemployment and the business cycle in a small open economy: G.M.M. estimation and testing with French data

What is a relevant model for the European business cycle? In this paper, the empirical performances of three models are compared: a canonical Walrasian R.B.C. framework, its extension to the case of a small open economy, and a version of this model with search and wage bargaining on the labor market. Structural parameters of the models are estimated using G.M.M. and their abilities to reproduce the French business cycle, taken as representative of the European business cycle, are tested. Only the small open economy with unemployment is able to generate theoretical moments that match their empirical counterparts.     

Efficiency wages,wage comparison,and public sector budgeting

We develop a government decision model where efficiency wage mechanisms affect the allocation of resources between different public services. We show how the introduction of interdepartment wage relativities modifies the standard Solow wage setting conditions. We compare the outcome under centralised and decentralised wage setting, and show that a decentralised wage setting system creates a distortion. Finally, we discuss the possibility of elimination this distortion using alternative financing systems.Final version: 08 April 2003JEL Classification: H23, J45We are grateful to Jan E.

Strategic militancy and the probability of strikes in union-firm bargaining

The paper provides a model that explains the probability of strikes by the union's use of militancy as a strategic tool in bargaining. Militants are useful because they provide a credible threat, hence enhancing the union's bargaining position. Using a multi-stage bargaining game, we show that, in general, militants will be used by the union as a strategic tool. The strategic benefit of militancy is reflected by the fact that the wage and employment level will be higher in a union that uses militants, compared to a union that does not. We use the model to show that the level of militancy and the probability of a strike decrease with the union's power. This suggests that policies that increase the strength of the union will have, at least, a partial positive effect on social welfare. We also show that the model can be viewed as providing an equilibrium of a repeated game, an interpretation that can explain the probability of strikes even in the absence of militants.     

Collective Household Models: Principles and Main Results

In the traditional approach to consumer behaviour it is assumed that households behave as if they were single decision‐making units. This approach has methodological, empirical and welfare economic deficiencies. A valuable alternative to the traditional model is the collective approach to household behaviour. The collective approach explicitly takes account of the fact that multi‐person households consist of several members which may have different preferences. Among these household members, an intrahousehold bargaining process is assumed to take place. In addition to providing an introduction to the collective approach, this survey intends to show how different collective household models, each with their own aims and assumptions, are connected.     

MIND THE GAP: UNEMPLOYMENT IN THE NEW EU REGIONS

Abstract.  The paper surveys the theoretical and empirical literature on regional unemployment during transition in Central and Eastern Europe. The focus is on optimal speed of transition (OST) models and on comparison of them with the neo-classical tradition. In the typical neo-classical models, spatial differences essentially arise as a consequence of supply side constraints and institutional rigidities. Slow-growth, high-unemployment regions are those with backward economic structures and constraints on factors mobility contribute to making differences persistent. However, such explanations leave the question unanswered of how unemployment differences arise in the first place. Economic transition provides an excellent testing ground to answer this question. Pre-figuring an empirical law, the OST literature finds that the high degree of labour turnover of high unemployment regions is associated with a high rate of industrial restructuring and, consequently, that low unemployment may be achieved by implementing transition more gradually. Moreover, international trade, foreign direct investment and various agglomeration factors help explain the success of capital cities compared to peripheral towns and rural areas in achieving low unemployment. The evidence of the empirical literature on supply side factors suggests that wage flexibility in Central and Eastern Europe is not lower than in other EU countries, while labour mobility seems to reinforce rather than change the spatial pattern of unemployment.     

效率工资的必要条件与经济效应

索洛模型和萨默斯模型存在局限性,在建立效率工资一般模型时,应当同时考虑到绝对工资水平、相对工资高低和失业率对工人劳动效率的影响。效率工资机制依赖于两个必要条件：间接计量的工资形式和竞争关系的存在。当效率工资的条件成立时,工资调整将存在粘性,均衡工资高于劳动力市场出清工资,且存在均衡失业。     

The Living Wage and the Effects of Real Minimum Wages on Part-Time and Teen Employment

In many parts of the country, campaigns are being carried out and laws are being passed whose aim is to establish, among other things, standards for contracting out public services and setting acceptable living wages that will provide employees decent living standards. Living wages have economic consequences on employment of different groups of workers such as part-time, teenagers, and women and detailed data are needed to measure those effects. In the absence of such data and because of the strong link between living and minimum wages, this study tests the potential impact of living wages by using the model of minimum wages. The study documents a negative and significant relationship between real minimum wages and the employment levels of the various groups. The study also recommends better training and education, free competition in the labor market, and fair compensation based on the workers productivity as justifiable means to achieve a sustainable level of living wages without causing an unemployment repercussion.     

Benefit shifting: The case of sickness insurance for the unemployed

This study describes the probability of transition from unemployment with unemployment insurance (UI) to sickness insurance (SI), using a proportional hazard duration model and a large register-based dataset. The combination of limited UI duration and the fact that SI rights do not depend on remaining UI, creates an incentive to use SI to effectively extend UI. The separate effects of elapsed unemployment duration and of UI duration on hazard rates are identified through a reform of the UI system. The estimated hazard rate for transition from unemployment to SI increases sharply the last months before UI exhaustion. The spikes are larger for diagnosis for mental illness, and vary across individuals, but are present for all groups and all diagnoses.
