Given the clear development of the educational mismatch phenomenon in our advanced economies, it seems interesting to investigate the effects of such phenomenon on the labour market. Based on available databases, this thesis gets into the research area of new working organizations and their effects on firm performance in a broader sense, by relying on a double stance. From the firm’s point of view, it analyses how educational mismatch impacts firm productivity (Chapter 2) and profitability (Chapter 3), according to different working environments. Chapter 2 provides first evidence on whether the direct relationship between educational mismatch and firm productivity varies across working environments, materialized as a socially responsible environment and a challenging environment. The results show that corporate social responsibility creates a working environment that fosters the positive impact of over-education on productivity, suggesting that socially responsible firms are more able than others to take advantage of the surplus knowledge of their over-educated workers. When investigating the role of a challenging environment, our results show that over-educated workers are more productive in firms that (i) require higher skills, (ii) rely on high-technological/knowledge processes, and (iii) operate in a more uncertain economic context, these three environments materializing a challenging situation. Chapter 3 reveals a profit-ability profile in the form of an inverted L with, at firm level, under-education being associated with a negative impact on profits, whereas higher levels of normal and over-education are associated with positive returns for firms. It also underlines caveats of relying on human capital hypothesis since increasing educational norms is associated with productivity gains that outpace hikes in labour costs, with the returns, in the case of Belgium, being captures by firms in the form of higher profits. Finally, it shows that in the particular context of high-tech industries, over-education could be a profitable strategy because hiring above educational norms leads to higher levels of profitability.From the workers’ point of view, this thesis analyses the wages impacts of educational mismatch by deepening and expanding the educational mismatch phenomenon to the skills mismatch phenomenon. Chapter 4 investigates the impact of educational and skills mismatches on workers’ wages by relying on three mismatch situations: (i) the apparent matching, where a worker is found to be properly educated but over-skilled; (ii) the apparent over-education, where a worker is found to be over-educated but properly skilled; and (iii) the genuine over-education, where a worker is found to be over-educated and over-skilled. Beside these considerations, this chapter also analyses whether the origin of the worker may influence the wage response to educational and skills mismatches. The results show that all specifications of over-education and over-skilling impact wages negatively, with the highest penalties for genuine over-education. When investigating differences between native and immigrant workers, the results suggest that immigrants suffer from a slightly higher pay penalty than natives. European immigrant and native workers thus do not seem to be that differently impacted by mismatches in terms of education and/or skills. / Doctorat en Sciences économiques et de gestion / info:eu-repo/semantics/nonPublished

This dissertation consists of three chapters, which focus jointly on the effects of education policy on the functioning of labor markets.De-industrialization and technological progress have changed job markets fundamentally. The most fundamental change is that the concept of a worker as a unit of production relatively insensitive to inherent characteristics has been overthrown. Service sectors that have taken over from manufacturing as the engines of economic activity rely primarily on human capital for autonomous production. This is especially true for internationally tradable services. Their stark development was rendered possible by the informationcommunication revolution. Skills and talent, as well as their allocation to suitable tasks matter for production, now more than ever. We argue in this dissertation that the ability of education policy to facilitate optimal task allocation plays a role in maximizing aggregate production and in influencing education earnings premia, as well as employment volumes in various sectors of activity. / Doctorat en Sciences économiques et de gestion / info:eu-repo/semantics/nonPublished

La réduction de l’usage des dispositifs de sortie anticipée et l’augmentation de la durée de vie à l’emploi se sont imposées comme de réels objectifs. Plusieurs réformes – implémentés, notamment, de façon non coercitive au niveau Européen – sont venues quantifier de tels objectifs. L’augmentation du taux d’emploi des travailleurs âgés de plus de 55 ans et l’augmentation de l’âge effectif moyen de la retraite sont tant d’outils quantitatifs qui servent une même finalité :l’augmentation de la participation au marché du travail des travailleurs âgés. L’une des résultantes de ces réformes est le développement, notamment en Belgique, de mécanismes de sortie partielle de l’activitié. En conséquence, les fins d’activité professionnelles prennent désormais des formes plus complexes, faites d’imbrications de différents statuts dans et en dehors du marché du travail. La thèse – qui croise une analyse des évolutions sociales de l’emploi des travailleurs âgés et une analyse longitudinale des parcours professionnels – est divisée en trois chapitres qui ont trait successivement aux indicateurs utilisés pour quantifier la sortie anticipée de l’emploi, au développement des instruments de réduction du temps de travail en fin de carrière et à l’impact des réductions du temps de travail en fin de carrière sur l’emploi des jeunes. Le premier chapitre prend appui sur une analyse macrosociologique des dynamiques du marché du travail. En mettant l’accent sur la sortie anticipée de l’activité professionnelle en tant que problème social, nous interrogeons, d’une part, l’écart temporel qui existe entre l’âge de la sortie de l’activité professionnelle et l’âge de la retraite et, d’autre part, les différents mécanismes qui sont utilisés en Europe pour sortir prématurément du marché du travail. La première partie repose principalement sur une analyse détaillée de l’indicateur « âge effectif moyen de la retraite » fourni par l’OCDE. Une analyse longitudinale (report de statut d’une année à l’autre) est également réalisée. La seconde partie, quant à elle, utilise une classification hiérarchique et évalue l’évolution des résultats des politiques publiques en matière d’usage de statuts entre 2000 et 2010. Le second chapitre analyse les politiques de réduction du temps de travail destinées aux travailleurs âgés. Plusieurs aspects sont étudiés. La première partie prolonge l’analyse comparative qui a été développée dans le premier chapitre en comparant l’évolution des politiques publiques en matière de transitions des individus d’un statut vers un autre (emploi, chômage et inactivité). La seconde partie met l’accent sur le développement récent de « statuts composites » – terme que nous utilisons ici pour décrire la combinaison d’une position sur le marché de l’emploi et de prestations sociales. Enfin, les troisième et quatrième parties s’intéressent à l’évolution législative et empirique de deux dispositifs :le crédit-temps (en Belgique) et le cumul emploi-retraite (en France et en Belgique). Enfin, le troisième chapitre propose une analyse de la notion de partage d’emploi entre générations. Une première partie étudie l’impact des variations économiques sur l’emploi des jeunes générations et des travailleurs âgés dans les pays européens. L’analyse, descriptive, prend appui sur trois notions (synchronie, hystérèse et dyschronie) qui décrivent les impacts différenciés des variations économiques sur les transitions professionnelles. La seconde partie analyse, pour le cas de la Belgique, le phénomène de partage d’emploi entre générations et la notion de « lump of labour fallacy ». Sur base des données issues du Datawarehouse Marché du Travail et Protection Sociale, deux régressions logistiques sont réalisées afin d’évaluer l’impact de l’usage des différents statuts composites utilisés par les travailleurs âgés sur l’emploi des jeunes. / The reduction in the use of early retirement schemes, and, consequently, the increase in the duration of the working life have emerged as real targets. Several non-coercive measuring instruments have been implemented by European public policy for quantifying these targets. For instance, the increase in the employment rate of workers aged over 55 years old and the increase of the average effective age of retirement are quantitative tools used of achieving the same purpose: increasing the participation in the labour market of the older workers. One of the effects of these reforms has been the development of part-time early retirement arrangements, particularly in Belgium. Consequently, ends of professional careers take more complex forms characterized by interconnections of different statuses within and outside the labour market. The thesis – crossing an analysis of the evolution of the employment participation of older workers and a longitudinal analysis of professional careers – is divided into three chapters relating successively to indicators used for quantifying early withdrawals, the development of instruments aiming at reducing working time at the end of the career and the impact of working time arrangements at the end of the career on youth employment. The first chapter is based on a macro-sociological analysis of the dynamics of the labour market. First, by focusing on the early withdrawal of the older workers as a social problem, the thesis analyses the time gap between the withdrawal age and the compulsory retirement age. Second, the large set of arrangement used in Europe for leaving prematurely the labour market is examined. The first part is mainly based on a detailed analysis of the "average effective retirement age" indicator provided by the OECD. A longitudinal analysis (report of statuses from one year to the next) is also performed. The second part uses a hierarchical classification (clustering) and evaluates the evolution of the public policies effects between 2000 and 2010.The second chapter focuses on the working time reduction policies dedicated to older workers. Several aspects are reviewed. The first part extends the analysis developed in the first chapter by comparing the evolution of public policies on individual’s transitions from one status to another. The second part focuses on the recent development of "composite statutes" – a notion used to describe the combination of a position on the labour market and social benefits. Finally, the third and fourth parts focus on the legislative and the empirical evolution of two specific arrangements: the time credit (Belgium) and the combination of work and employment (France and Belgium).The third chapter provides an analysis of social rapports between generations on the labour market. The first part examines the impact of economic changes on the employment of younger generations and older workers in European countries. The analysis is based on three economic concepts – synchrony, hysteresis and dyschrony – describing the differentiated impact of economic changes on employment transitions. The second part, focusing on Belgium, examines the phenomenon of job sharing between generations and the concept of "lump of labour fallacy". Based on data derived from the Datawarehouse Labour Market and Social Protection, two logistic regressions are performed in order to evaluate the impact of the different composite statutes dedicated to older workers on the youth employment rate. / Doctorat en Sciences politiques et sociales / info:eu-repo/semantics/nonPublished

This thesis explores the entire cycle of education, from initial access to schooling, over degree completion, to returns to education. Despite recent gains in increasing access, an tens of millions of children worldwide are still out of school. Abolishing school fees has increased enrollment rates in several countries where enrollments were low and fees were high. However, such policies may be less effective, or even have negative consequences, when supply-side responses are weak. The first part of the thesis evaluates the impacts of a tuition waiver program in Haiti, which provided public financing to nonpublic schools conditional on not charging tuition. The chapter concludes that school's participation in the program results in more students enrolled, more staff, and slightly higher student-teacher ratios. The program also reduces grade repetition and the share of overage students. While the increase in students does not directly equate to a reduction in the number of children out of school, it does demonstrate strong demand from families for the program and a correspondingly strong supply response from the nonpublic sector.Pertaining degree completion, it is well established that natural disasters can have a negative effect on human capital accumulation. However, a comparison of the differential impacts of distinct disaster classes is missing. Using census data and information from DesInventar and EMDAT, two large disaster databases, the second part of the thesis assesses how geological disasters and climatic shocks affect the upper secondary degree attainment of adolescents. The chapter focuses on Mexico, given its diverse disaster landscape and lack of obligatory upper secondary education over the observed time period. While all disaster types are found to impede attainment, climatic disasters that are not infrastructure-destructive (e.g. droughts) have the strongest negative effect, decreasing educational expansion by over 40%. The effects seem largely driven by demand-side changes such as increases in school dropouts and fertility, especially for young women. The results may also be influenced by deteriorated parental labor market outcomes. Supply-side effects appear to be solely driven by infrastructure-destructive climatic shocks (e.g. floods). These findings thus call for differential public measures according to specific disaster types and an enhanced attention to climatic events given their potentially stronger impact on younger generations.It is also widely appreciated that natural disasters can have negative impacts on local labor market outcomes. However, the study of differential types of negative capital shocks, the underlying labor market mechanisms, and the context of the poorest countries have been neglected. Following testable predictions of economic theory, the third part of the thesis exploits the exogenous variation of destruction of human and physical capital caused by the 2010 Haiti earthquake to disentangle the differential impact on local individual monetary returns to education. Employing individual-level survey data from before and after the earthquake the chapter finds that the returns decreased on average by 37%, especially in equipment-capital intensive industry. Higher educated individuals adjust into low-paying self-employment or agriculture. The returns are particularly shock-sensitive for urban residents, migrants, males, and people over age 25. / Doctorat en Sciences économiques et de gestion / info:eu-repo/semantics/nonPublished
