Workplace Heterogeneity and the Returns to Versatility
2021
Abstract In the canonical random on-the-job search model with continuous firm heterogeneity, I show that a mean-preserving spread of the firm-productivity distribution raises the returns to mobility, i.e., the inter-firm mobility of workers as measured by the number of outside contacts per employment spell. Both sorting and rent-share mechanisms play a role. In a further contribution, I distinguish frictional and structural impediments to mobility in order to establish a link between mobility and skills via the concept of versatility. Versatility enhances a person’s mobility since a mismatch between job requirements and the person’s skill set is less likely to occur. I provide some statisti…
Back to School : Labor-Market Returns to Higher Vocational Schooling
2019
This paper examines the labor-market returns to a new form of postsecondary vocational education: vocational master's degrees. We use individual fixed effects models on a matched sample of students and non-students from Finland to capture any time-invariant differences across individuals. We find that attendance in vocational master's programs leads to an earnings increase of more than seven percent five years after entry. The estimated effect remains positive even if selection on unobservables is twice as strong as selection on observables. Earnings gains are similar by gender and age, but they are marginally higher for those in the health sector than for those in the business or technolog…
Who turns to entrepreneurship later in life? - Push and pull in Finnish rural and urban areas
2014
Age is an important factor in entrepreneurship. The paths into entrepreneurship at a later age may be varied. Self-employment in later life may be either a form of partial retirement or a career option. Older individuals may also be pushed into self-employment. The focus of this paper is on the career choices of older individuals and their background motivations in Finland. The purpose is to analyse the factors and motives in terms of the push and pull dichotomy that lead individuals to enter self-employment at older ages in different types of labour markets in Finland, viz., rural and urban areas. Although some studies have focused on transitions to self-employment among older workers, que…
Labor market participation, employability and and basic skills: the French case
2013
En ligne sur http://cemapre.iseg.utl.pt/educonf/2e3/files/submissions_to_web/Branche-Seigeot%20Aline.doc; The development of Information and Communication Technologies (ICT) and the important technological but also organizational innovations during the last decades have transformed the labor market and the jobs nature. One major consequence of this on employment has been the gradual rise in qualifications' structure sought and demanded by employers. However, the expansion of higher education contributed to depreciate diplomas proportionately more widespread in the labor market due to a greater skills' heterogeneity of their owners. Since high basic skills levels protect against unemployment…
Les motivations des administrateurs des coopératives : une question de gouvernance revisitée par les approches de la proximité
2016
National audience; Comprendre les motivations des acteurs de gouvernance peut contribuer à favoriser la réussite et la pérennité de l’entreprise. L’article s’intéresse aux motivations des administrateurs pour mieux appréhender ce qui les incite à exercer pleinement leur rôle et à s’impliquer pour contribuer à l’atteinte des objectifs de la société. L’étude porte sur un type spécifique d’organisation, les coopératives, dont l’engagement des membres est souvent cité comme particulièrement fort. Les approches de la proximité sont mobilisées pour analyser les quatre principales motivations identifiées chez les administrateurs des coopératives : l’envie d’accroître leurs compétences, celle de dé…
The paradoxical management of service skills
2015
This paper focuses on service skills which are mobilized by front office agents when they are involved with customers. These skills are most of the time tacit. We consider that the way in which firms recognize these skills and contribute to their development is an important management issue. It is all the more important that a lot of jobs combine poor levels of qualification and highly situated skills.
Unemployment Transitions to Stable and Unstable Jobs Before and During the Crisis
2014
Using administrative records data from Spanish Social Security, we analyse the pattern and the determinants of individual unemployment benefit spell durations. We compare a period of expansion (2005-2007) and the recent recession (2009-2011), allowing us to determine the impact of the current crisis. In line with the duality that characterizes the Spanish labour market, we distinguish between exits to a stable job and exits to an unstable job. We estimate a Multivariate Mixed Proportional Hazard Model for each time period. We find similar effects of the crisis for stable and unstable jobs, which are particularly strong in the first year of the spell. Moreover, slight negative duration depen…
Returns to Schooling in Spain. How Reliable Are IV Estimates?
2001
This paper studies the Ordinary Least-Squared (OLS) and Instrumental Variables (IV) estimates of the returns to schooling for male workers in Spain. OLS estimates are often biased due to the endogeneity of schooling, measurement errors or omitted variables. Proper IV estimates correct this bias. The reliability of family background, natural experiments (based on changes in the education system and season of birth) and the availability of a college in the province is checked using Spanish data. The results suggest that background and college availability are valid instruments and that the IV estimates of the returns to schooling are higher than OLS estimates. These results are in line with t…
Matching inefficiencies, regional disparities and unemployment
2009
. In this paper we apply a stochastic frontier approach to examine how matching inefficiencies and regional disparities in structural factors contribute to regional and aggregate unemployment. Our results suggest that there would be a substantial decline in aggregate unemployment if (i) all local labour offices operated with full efficiency or (ii) they shared the same structure of job seekers and vacant jobs as the most favourable office. In the former case an increase in hirings would lower the average unemployment rate by 2.4 percentage points. In the latter case the decrease would be 1.4 percentage points. Further, we find that fixed effects are positively correlated with both a more f…
Vibrations of free and embedded anisotropic elastic spheres:Application to low-frequency Raman scattering of silicon nanoparticles in silica
2004
Vibrational mode frequencies and damping are calculated for an elastic sphere embedded in an infinite, homogeneous, isotropic elastic medium. Anisotropic elasticity of the sphere significantly shifts the frequencies in comparison to simplified calculations that assume isotropy. New low-frequency Raman light scattering data are presented for silicon spheres grown in a ${\mathrm{SiO}}_{2}$ glass matrix. Principal features of the Raman spectrum are not correctly described by a simple model of the nanoparticle as a free, isotropic sphere, but require both matrix effects and the anisotropy of the silicon to be taken into account. Libration, not vibration, is the dominant mechanism.
