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.     

Persistence of Employment Fluctuations: A Model of Recurring Job Loss

Standard models of employment fluctuations cannot reconcile the unemployment rate's remarkable persistence with the high job-finding rates found in worker flows data. A matching model emphasizing high hazard rates among newly formed firm–worker matches can resolve this shortcoming. In the model, matches are experience goods; consequently, newly employed workers face higher hazard rates. Following a job loss, workers may experience several short-lived jobs before finding stable employment. At an aggregate level, an initial burst of job loss precipitates a steady flow of recurring job loss. A simulation shows that this recurring job loss can account for the fact that the unemployment rate remains elevated for as much as 4 or 5 years following an initial jump.     

A better job thanks to personal networks? An evaluation for migrants who arrived in France before age 18

It is more difficult for migrants than natives to find a job in their host country, so many of them have to accept, at least temporarily, a job that is below their level of qualification. This represents a waste of human capital for society and can undermine social cohesion. Relying on social relationships might help them to bypass some of the obstacles that prevent them from finding a job that matches their skillset. We focus on migrants who arrived in France before the age of 18 years, who were educated entirely or partially in France. We use the rich French Trajectories and Origins dataset for 2009 to study the impact of personal contacts on the quality of the current employment. We measure the job quality using an indicator based on the educational requirement for a given occupation. To address the endogeneity between our dependent variable (holding a suitable job or not) and the variable of interest (employment found through a personal contact or not), we use the variable ‘sibling(s) in France’ as an instrument: this variable influences an individual’s probability of finding a job through contacts but does not influence directly the quality of the employment. Our results indicate that for these migrants, finding a job through personal contacts strongly and positively impacts the occupational status attained: it raises both women’s and men’s probability of holding a suitable job by more than 0.40 points.     

Sensitivity of Job Destruction to Vintage and Tenure Effects

Matching models with endogenous job destruction typically deliver excessively volatile job destruction and moderate volatility of vacancies. In our model, vintage and tenure effects promote the creation of new matches that are temporarily more productive, while reducing the survival of temporarily less productive matches. This cleansing effect produces a counter‐cyclical inflow into unemployment, removes the strong response of job destruction to productivity shocks, and generates a downward‐sloping Beveridge curve, as in the data. The model also generates more volatility in vacancies, the job‐finding rate, and labor‐market tightness.     

Duration of disability,job mismatch and employment outcomes

Workers with disabilities have functional limitations that affect their productivity in some, but not necessarily all, jobs. Workers who find a job that is a good match for their functional limitations (i.e. a job where their limitations have little or no impact on important job functions) should expect better employment outcomes (e.g. higher wages, longer job tenure) than workers with similar disabilities who are mismatched in their jobs. Merging data from the Survey of Income and Program Participation with O*Net data on job demands, we construct two continuous measures of job mismatch for workers with physical disabilities. We then extend the literature on disability and employment by exploring relationships between duration of disability, job mismatch, wages and hours worked. The results indicate that workers with long durations of disability are employed in jobs that are a better match to their physical limitations than are similar workers with shorter durations of disability. And, workers who are mismatched earn lower wages and work fewer hours than their counterparts whose jobs are a better match. Overall, the findings suggest that disability employment policies should include systematic efforts to help workers with disabilities find good job matches.     

The extensive margin,sectoral shares,and international business cycles

Abstract This paper documents some previously neglected features of sectoral shares at business cycle frequencies in OECD economies. We find that the non‐traded output share is as volatile as aggregate GDP and for most countries is countercyclical. While the standard international real business cycle model has difficulty in accounting for these properties of the data, an extended model that allows for sectoral adjustment along both the intensive and the extensive margins does a much better job of replicating these statistics. The model also matches better the correlation between relative consumption growth and real exchange rate changes, a key measure of international risk‐sharing.     

Job creation and job types – New evidence from Danish entrepreneurs

We extend earlier analyses of the job creation of start-ups versus established firms by considering the educational content of the jobs created and destroyed. We define education-specific measures of job creation and job destruction at the firm level, and we use these measures to construct a measure of “surplus job creation”, defined as jobs created on top of any simultaneous destruction of similar jobs in incumbent firms in the same region and industry. Using Danish employer-employee data from 2002–2007 that identify the start-ups and that cover almost the entire private sector, these measures allow us to provide a more nuanced assessment of the role of entrepreneurial firms in the job-creation process than in previous studies. Our findings show that although start-ups are responsible for the entire overall net job creation, incumbents account for more than one-third of net job creation within high-skilled jobs. Moreover, start-ups “only” create approximately half of the surplus jobs and even less of the high-skilled surplus jobs. Finally, our approach allows us to characterise and identify differences across industries, educational groups and regions.     

Wage Bargaining Versus Efficiency Wages: A Synthesis

We construct a model integrating the efficiency wage model of Shapiro–Stiglitz (1984) (SS), with an individual wage bargaining model in the Diamond–Mortensen–Pissarides (DMP) tradition where firms and workers form pairwise matches. We show that when workers may threaten to shirk on the job and there is individual wage bargaining, the wage is always higher and employment lower than in either the SS model, or the (appropriately modified) DMP model. When firms determine workers' efforts unilaterally, efforts are set inefficiently low in the SS model. In the bargaining model, effort is higher, and is first best when the worker non–shirking constraint does not bind. The overall equilibrium allocation may then be more or less efficient than in the SS model, but is always less efficient than in a pure bargaining model with no moral hazard.     

Job matching when employment contracts suffer from moral hazard

We consider a job matching model where the relationships between firms and wealth-constrained workers suffer from moral hazard. Specifically, effort on the job is non-contractible so that parties that are matched negotiate a bonus contract. Higher unemployment benefits affect the workers' outside option. The latter is improved for low-skilled workers. Hence they receive a larger share of the surplus, which strengthens their effort incentives and increases productivity. Effects are reversed for high-skilled workers. Moreover, raising benefit payments affects the proportion of successful matches, which induces some firms to exit the economy and causes unemployment to increase.     

Semi-Parametric Comparison of Stochastic Volatility Models using Realized Measures

This paper proposes a procedure to test for the correct specification of the functional form of the volatility process within the class of eigenfunction stochastic volatility models. The procedure is based on the comparison of the moments of realized volatility measures with the corresponding ones of integrated volatility implied by the model under the null hypothesis.
We first provide primitive conditions on the measurement error associated with the realized measure, which allow to construct asymptotically valid specification tests.
Then we establish regularity conditions under which the considered realized measures, namely, realized volatility, bipower variation, and modified subsampled realized volatility, satisfy the given primitive assumptions.
Finally, we provide an empirical illustration based on three stocks from the Dow Jones Industrial Average.     

Graduate overeducation as a sheepskin effect: evidence from Northern Ireland

This article examines the nature of graduate overeducation amongst a group of applicants to a graduate conversion programme. It was found that while a substantial proportion of earnings differentials were associated with a mismatch between individual skill levels and job requirements, wage gaps were still likely to occur should such mismatches be eliminated. The evidence suggests that graduate wage levels are heavily related to sheepskin effects associated with the attainment of jobs with graduate level entry requirements. These sheepskin effects suggest that the process of job categorization is arbitrary in nature, with stated job requirements somewhat independent of actual skill requirements. The analysis suggests that graduate overeduction is better understood within the context of both skill and categorization mismatches as opposed to skill matches alone.     

Admission standards,student effort,and the creation of skilled jobs

We consider the implications of expanding enrollment through lower standards in a model with human capital externalities and a market failure. Workers and firms make uncoordinated investment choices prior to random matching. Investment choices depend on the expected productivity of the counterpart in production. The setting generates a potential human capital externality as a more skilled labor force induces more skilled job openings. Exploiting the externality is complicated by a market failure which may cause some workers to earn a degree but not put forth the effort required to become highly skilled. We show that beyond a threshold, increased enrollment through low standards can be poor policy. Policies which increase returns to agents and firms in best matches can improve outcomes.     

Assessing the economic impact of entrepreneurship on a regional economy using social accounting matrices: the case of Andalusia

This article analyses the impact that entrepreneurial activity has, from the economic point of view, on a regional economy (Andalusia), based on a Social Accounting Matrix linear model. Moreover, to measure entrepreneurship at regional level, it is defined what can be considered an entrepreneurial initiative company from a quantitative point of view. The results obtained, in terms of Production, GDP and job creation, show how entrepreneurship, in the case of Andalusia, contributes to the sustainability of the economy, its growth and, above all, the reduction of unemployment in the short term.     

Learning to update your reservation wage while looking for a new job

We combine post-displacement survey data with information from personnel files of a displacing firm in order to reveal sources of worker heterogeneity in search time and wage losses. The Fokker Personnel Files and Survey are described in detail. We develop a dynamic reservation wage with updating. The method of updating is based on the simple idea that job seekers are informed about successful matches of their former colleagues similar to them. The data offer empirical support for the updating model.     

中国城市的职业流动:水平与差异

社会学家传统上使用流动表考察职业流动状况。运用人口学方法提出一种新的职业流动水平的测量指标,即总和流动率。利用2003年全国综合社会调查数据,通过总和流动率的计算,近40年来我国城市的职业流动率出现了大幅度增长。按照2002年的职业流动率水平,我国城市地区人们一生将从事三份工作或职业。同时,职业流动率的社会经济差异非常明显,较高的职业流动率发生在男性、未婚、少数民族、初中受教育程度、党员和流动人口群体中。对职业流动率测量作了新探索,提出的总和流动率概念简洁、计算方便,并具有标准化指标性质,故有一定的学术和应用价值。     

Choice and success of job search methods

Job seekers influence the arrival rate of job offers by the choice of search effort and the search methods they use. In this paper we empirically investigate the effect of different search methods on search outcomes. We use unique data on the search behavior of job seekers in Austria, which matches survey information with administrative records. We analyze the quality of job matches in terms of wages and job durations for employed and unemployed workers. We find that the public employment office specializes in the support of low quality workers. For them it is equally efficient as other search channels.     

Does population density matter in the process of matching heterogeneous job seekers and vacancies?

This paper studies the matching of job seekers and vacant jobs using data on local labour markets. We estimate differences in the ability of the local markets to form new matches and trace whether these differences can be explained by the differing population densities across markets or by the heterogeneity of job seekers measured by the distribution of their education level. We find that high-density areas are more efficient in forming matches than other areas despite frictions caused by the wider heterogeneity of job seekers in those areas than elsewhere.

A DYNAMIC ANALYSIS OF EDUCATIONAL ATTAINMENT,OCCUPATIONAL CHOICES,AND JOB SEARCH*

This article examines career choices using a dynamic structural model that nests a job search model within a human capital model of occupational and educational choices. Wage growth occurs in the model because workers move between firms and occupations as they search for suitable job matches and because workers endogenously accumulate firm and occupation specific human capital. Simulations performed using the estimated model reveal that both self‐selection in occupational choices and mobility between firms account for a much larger share of total earnings and utility than the combined effects of firm and occupation specific human capital.     

Changes in Occupational Tasks and Their Association with Individual Wages and Occupational Mobility

This study provides novel evidence on the relevance of task content changes between and within occupations to wage dynamics of occupational changers and stayers. I use individual‐level, cross‐sectional data featuring tasks performed on the job to compute a measure of proximity of job contents. Then, I merge this measure to a large‐scale panel survey to show that occupational changers experience a wage growth that is declining when the accompanying alterations in task contents are big. For occupational stayers, alterations in task contents generate a positive wage component, beyond tenure effect. However, the results are not robust with respect to the choice of proximity measure and over time.     

Returns to job satisfaction in the presence of horizontal mismatch

ABSTRACT

In this paper, we study the relationship among horizontal mismatch, job satisfaction and wages using data from the 2013 Scientists and Engineers Statistical Data System (SESTAT). Estimates from 2SLS indicate that 1) field-occupation match in the highest degree has a positive effect on job satisfaction and wages; and 2) controlling for field-occupation matches, job satisfaction has a positive but diminishing effect on wages with a large heterogeneity across different age groups. In addition, we also distinguish between job satisfaction arising from benefits and job satisfaction that is productivity enhancing and find both to have a positive but nonlinear effect on wages.
