An empirical approach on labour segmentation. Applications with individual duration data

This article proposes empirical tools to account for the role of heterogeneities in the labour matching process, and shows an application to the Andalusian labour market which relies on individual data. The central idea of the paper is that the labour market is segmented, and this segmentation can be treated empirically by grouping workers, jobs and matches into labour groups according to their characteristics. In a segmented labour market the probability that a match occurs in a particular job group affects the probability that a match occurs in a particular worker group or vice versa. We propose two empirical measures related to this idea: propensity to match, and segmentation in worker and job groups. The usefulness of this empirical framework is shown by its application to different labour market analyses. Firstly, we use a clustering methodology, based on a similarity measure, to obtain a better overview of the structure of the labour market. Secondly, we propose a measure of mobility based on our similarity measure, and estimate a regression model that relates mobility to worker and job characteristics and to the economic cycle. Finally, these tools are included in an unemployment duration model. The proposed methodology may be useful in labour intermediation by helping seekers to follow a ‘roadmap’ of successful paths.     

APPRENTICES AND YOUNG WORKERS: A STUDY OF THE NORWEGIAN YOUTH LABOUR MARKET

Apprenticeship programmes are in many countries important stepping stones into the labour market. However, recruitment of apprentices seems to follow the business cycle. This pattern may be caused by firms' contemporaneous demand for labour, but may also be consistent with an investment hypothesis. A model, in which the tightness in the labour market is taken into account, is tested on a sample of Norwegian quarterly firm‐specific data. The empirical findings give moderate support to an investment hypothesis. The apprentices substitute to some degree for skilled labour but are recruited primarily based on the labour market situation. The wage level plays a minor role for recruitment of apprentices.     

关于劳动力市场分割动因的三种解释——评述与拓展

20世纪80年代中期以来,新古典经济学凭借对内部劳动力市场理论的深入拓展,在SLM理论的研究中日益占据主导地位,然而均衡分析的思路却打破了资本主义生产关系制造分割的劳动力市场这一根本性的矛盾。以激进政治经济学派为代表的西方马克思主义经济学研究,通过对资本主义劳动过程和积累的社会结构的分析,在生产关系的层面对劳动力市场分割的形成和延续提供了进一步解释。而剑桥学派秉持的社会经济因素作用于劳动力市场结构形成的思路,无疑有助于解释劳动力供给和需求的结构如何"天然地"制造分割,将更广泛的社会经济因素引入了讨论。在全球化生产的背景下对上述理论进行评析、互动与拓展,可以为解释中国的劳动力市场分割提供一个更有益的方法论参考。     

The minimum wage and the Lithuanian labour market

This paper presents a comprehensive and non‐standard labour market analysis based on univariate and multivariate models for wages. The novelty of this paper lies in the use of non‐normalized cointegrating vectors for labour market analysis. Wages are the basis of labour market models, as well as the key factor for employees and employers; therefore, the central analytical axis is a classical wage bargaining process, where one side requires and the other side proposes a certain level of wages. Analysis is divided into two parts: foremost, a careful analysis of Lithuanian wages is conducted and a univariate model for the investigation of interactions between the minimum wage and the rest of the wages is proposed; only after the minimum wage model is drafted can the multivarate model for the whole economy be built up. Briefly, the methodology used in this article can be annotated as a synthesis of sequential theoretical and empirical considerations that combine the results of theoretical macroeconomics with data‐generating patterns and stylized facts. The model is considered as the final one only if macro‐theory preconditions, statistical prerequisites, and stylized real‐world requirements are met and fulfilled. In addition, this article gives an example and a quantitatively, as well as qualitatively, motivated suggestion as to how to incorporate minimum wages into econometric models and puts forward an explanation for why it is necessary to include minimum wage dynamics into labour market analysis. The article is nothing but an empirical case study that demonstrates how many minor details have to be taken into account until a realistic labour market model is built up. Although the paper deals with the labour market, the suitable application of time series methods is the main subject of the analysis.     

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.     

The Youth Labour Market in Australia*

This paper uses unit record data from the 1985 Australian Longitudinal Survey to review the major features of the youth labour market. It is shown that education plays an important role in determining the incidence of unemployment, wages, hours of work and access to training opportunities. Analyses of labour market dynamics indicates that the probability of leaving unemployment falls off substantially as the duration of the unemployment spell increases. A major conclusion of the paper is that the longer term unemployed appear to be segmented from other labour market participants. An implication of this finding is that there b very little which the longer term unemployed can do at the margin to influence their success other than adopt the most productive method of job search.     

Why do diplomas pay? An expanded Mincerian framework applied to Mexico

We compare four explanations for the value of diplomas, each of which has implications for unemployment and wage variation amongst graduates, most of which have not previously been tested for when seeking to explain the effects of diplomas. We test for these implications using a refined econometric framework, exploiting idiosyncrasies in Mexican labour market and educational institutions. Premiums in Mexico appear to result from diplomas tied to jobs with downwards rigid wages?–?an uncommon but simple explanation. The standard explanations, including screening, are not suggested by Mexican data. Our results illuminate how labour markets segmented by diplomas clear. This depends upon the nature of the labour market rigidities exactly as predicted by neoclassical theory.     

An evolutionary game theory approach to the dynamics of the labour market: A formal and informal perspective

A stylized fact of the labour market in developing countries is that it is highly segmented in informality. One of the main factors that induce workers and firms into informality is an excessive regulatory system that makes formal economy little attractive. This study aims to analyze the dynamics of workers and firms’ entrance and withdrawal of the formal and informal economy, assessing the impact of taxes by using an evolutionary game theory approach in which economic agents decide for one these markets according to the expected pay-off. Moreover, the optimal relation between regulatory and enforcement action by the government is evaluated.     

International outsourcing and the demand for skills

This paper explores the impact of international outsourcing on the demand for skills in three small and open EU economies. A model of variable costs and factor demand functions for different skill levels and imported as well as domestic materials are constructed. International outsourcing is treated directly as a substitution process between labour of different skills and imported inputs. The direct consequence of international outsourcing for labour is measured by the cross price elasticities. These cross price elasticities indicate a negative outsourcing impact on low- and medium-skilled labour in the three countries and on high-skilled labour in two out of the three countries. This outsourcing effect on labour is compared with the direct effect of embodied technical change and of the technical change bias. International outsourcing has a more unambigous and significant negative impact on labour than technical change. Technical change is either labour using (embodied technical change) or only slightly biased in favour of high-skilled labour. When the cost savings effect of international outsourcing is taken into account, an indirect positive stimulus for all skill categories arises from a greater demand for goods. It can be shown, that this indirect positive effect can compensate for a large part of the negative substitution impact of international outsourcing on labour.     

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.     

Labour mobility during transitionEvidence from Georgia1

This article deals with labour mobility in Georgia during economic transition. We use quarterly 1998–99 panel data to examine mobility across six labour market statuses (inactivity, unemployment, formal wage employment, informal wage employment, self‐employment and farming). Our findings are consistent with the hypothesis of labour market segmentation. Formal employment is preferred to informal employment. Unemployment is largely a queuing device for individuals with higher education waiting for formal jobs. Some self‐employment is subsistence activities and consistent with a segmented labour market, while other is high risk and potentially high return activities. Age, gender and education are significant determinants of labour mobility. Finally, informal employment serves as a buffer in times of recession – with farming and informal wage employment absorbing labour shed by other statuses during the Russian financial crisis.     

Market Structure and Fiscal Policy Effectiveness

In a monopolistic competition macromodel with endogenous market structure, the fiscal multiplier is shown to consist of two components. The first depicts the response of output to a fiscal expansion through the conventional channels that disregard the role of market imperfections. The second component captures the effects of firms' market power as well as the policy-induced change in market structure. The latter effect—which has not been taken into account in existing studies—is shown to be quite significant in raising the fiscal multiplier (even above unity) and in improving consumers' welfare when the labour market is competitive.     

Gender wage gap across the wage distribution in different segments of the Indian labour market, 1983–2012: exploring the glass ceiling or sticky floor phenomenon

Women’s participation in the Indian labour market is not only low but they are also engaged in low-productivity and low-paying jobs. Further, the labour market is segmented by gender, type of employment, sector and location of residence. This study makes an important contribution by examining gender wage gap in India across different segments of the labour market over the wage distribution using national-level representative data spanning the period 1983 to 2012. The empirical results suggest that (i) the male–female raw wage gap has declined over time across the wage distribution, (ii) the gender wage gap attributable to differing returns to characteristics has increased over time and there is evidence of convergence of productive characteristics of men and women, (iii) sticky floor rather than glass ceiling phenomenon is observed in all segments of the labour market and (iv) the adjusted wage gap suggests that women at the bottom of the distribution face higher discrimination than those at the top and this has increased over the years.     

Labour market segmentation and union wage gaps

Abstract

There has been a great deal of research regard the effects of unions on union – non-union wage gap. Most of the studies regarding the impact of unions on wages have assumed that apart from the division between union and non-union workers, the labour market is relatively homogeneous. A number of economists, however, have argued that the labour market is segmented, implying that there are distinct labour markets and that some workers employment opportunities are concentrated in “bad jobs” while other workers employment opportunities are concentrated in “good jobs” which are rationed.

This paper will explore whether the relative wage differential between union and non-union workers differs between the independent primary, subordinate primary and secondary labour markets. Labour market segments are defined using “job zones”. “Job zones” are distinct groups defined by the level of specific vocational preparation necessary for a particular occupation, allowing for the comparison of skill levels and training for each occupation. The data on “job zones” comes from the Occupational Information Network database (O?Net). We estimate separate equations for union and non-union workers in each segment using data from the Current Population Survey and calculate union non-union differentials for each labour market segment. The findings of this paper suggest that the greatest differentials are in secondary labour markets followed by differentials in the subordinate primary labour market and that the smallest wage differentials are in the independent primary labour market.     

Segmented labour markets and the estimation of wage functions

This paper uses a stratified random sample of private sector employees to estimate wage equations for both the male labour market as a whole and six ‘segments’ of the labour market, segement which are defined with respect to the industry and size characteristics of the employing establishmen. Highly conventional results are obtained when wage equations are estimated for the male labour market as a whole, or within two segements, comprising almost half the survey population. However, one can reject conclusively the hypothesis that the same estimating equation is appropriate for modelling wage determination in all segments and if a ‘human capital’ (HK) model is, within segements, tested against more appropriate alternative hypotheses for wage determination using the Davidson and Mackinnon (1981) methodology for the testing of non-nested hypotheses, the conclusion is that one should reject the HK specification and not reject the alternative.

It is therefore argued that the disaggregation of labour market data reveals differences in the wage determination process that are not consistent with the view that labour markets are ‘dualistic’ but are consistent with the view that are segmented.     

Bounded rationality,expectations, and child labour

This paper develops a model with overlapping generations, where the household's optimal fertility, child labour, and education decisions depend on the parents’ expectations or beliefs about the return to education. It is shown that there exists a range of parental income where the fertility rate is high and children participate in the labour market and receive an incomplete education if a parent believes the return to education is low. The act of participating in the labour market reduces the child's ability to accumulate human capital; thus, the action of sending a child into the labour market is sufficient to ensure that the parents’ initially pessimistic expectations are fulfilled. It is then shown that a one‐time policy intervention, such as banning child labour and mandatory education, can be enough to move a country from the positive child labour equilibrium to an equilibrium with no child labour.     

An Index of Segmentation in Local Labour Markets

This study tests for the existence of labour market segmentation by exploiting the variation in industrial structure across 59 labour market areas, as defined by MSAs. By creating an index of the relative explanatory power of standard and segmented earnings function models for each area, empirical evidence supports the hypothesis that segmentation exists and that the index reflects the degree of segmentation in local labour market areas.     

The impact of taxes on female labour supply

There is little agreement in economics on the factors influencing labour supply and hence on the impact of taxes. Within the marginal model, real wages and incomes are directing people's labour market behaviour independent of time and space, whereas the human resources approach takes account of the social environment and past behaviour. Even if strong assumptions are made, the neoclassical theory cannot predict the outcome of a wage increase. The labour supply response depends on the relative strengths of the substitution and the income effect. Since nonparticipation in the labour market is explained by a reservation wage being higher than the market wage, this is the only situation in which neoclassical theory would predict a rise in labour force participation with a wage increase. This case occured in a ‘natural experiment’ in Sweden. The Swedish tax system changed in 1971 from joint to separate taxation of spouses resulting in a substantial increase in the net wage of married women. This article investigates the impact of the change in the Swedish tax system on female labour force participation, concluding that it cannot explain the substantial rise in the participation rates of Swedish women. This is a significant result, questioning standard neoclassical theory and supporting the more institutional views of human labour market behaviour. That is that time and space as well as the social environment are important when analyzing labour supply. This will have consequences for international comparisons. Only factors which explain developments within one country might be relevant for explaining international differences, e.g. in labour force participation.     

Earnings functions: Testing for the demand side

To analyze labor market phenomena, one may simultaneously grade workers (by education) and jobs (by level of difficulty and complexity). Human capital theory predicts earnings based on only worker quality. Thurow's version of a segmented labor market theory predicts that only the job level is relevant, and the assignment theory predicts that both variables are relevant. Using three different data sets for The Netherlands, testing demonstrates convincingly the superiority of the assignment theory.     

Marx Inside the Circuit: Discipline device,wage bargaining and unemployment in a sequential monetary economy

The aim of this paper is to show that Marxian labour theory of value can be consistently interpreted in terms of the monetary circuit model, where firms need initial finance to start production and where the money supply is endogenous. In contrast to the recently revived Marxian monetary models, in particular the New Interpretation, it is argued here that although the money wage is bargained for on the labour market, the real wage is determined by firms' choices, since firms autonomously determine the structure of production and hence real consumption for the working class as a whole. This does not mean that firms are able to set the real wage without economic and social constraints. Starting from our circuitist reading of the labour theory of value and distribution, a model is developed in order to determine the level of employment and income distribution, on the assumptions that (i) the industrial reserve army affects wage bargaining and labour effort and that (ii) workers react to the failure of their expectations on the real wage by reducing their work intensity. In this context, it is shown that firms may increase their share of profits over time only be means of innovations.
