Ce travail constitué de trois chapitres cherche à analyser l’impact du salaire minimum sur l’économie des départements français d’Amérique en se limitant aux effets sur la distribution des revenus et la croissance économique.Dans le premier chapitre, l’accent est mis sur les inégalités salariales telles qu’elles existent aux Antilles-Guyane, en comparaison avec la situation en France métropolitaine. Les inégalités de revenus restent fortes entre les catégories socioprofessionnelles dans les DFA. Le salaire moyen de l’ensemble des salariés de France métropolitaine est supérieur à celui des DFA.Le second chapitre présente tout d’abord les aspects historiques et réglementaires qui caractérisent le salaire minimum français et celui d’autres pays d’Europe. Le SMIC se classe en quatrième position parmi les salaires minimum les plus élevés d’Europe, et la France, le pays développé comptant la plus forte proportion de salariés au SMIC. Dans les Départements Français d’Amérique, les salariés payés au SMIC, bien plus nombreux en proportion qu’au niveau national, sont le plus souvent des femmes, des jeunes, des personnes peu qualifiées occupant un emploi à temps partiel dans les secteurs des services et du commerce. Il met également en évidence les effets du salaire minimum et de ses revalorisations sur la formation des salaires et le coût du travail. Les effets de diffusion du SMIC sont faibles et temporaires, variant de 0,1 à 0,2% tant en approche macroéconomique que microéconomique. Les hausses du SMIC entraînent une augmentation du coût du travail pour partie compensée par les allègements de charges octroyés aux entreprises.Le troisième chapitre contribue à la mise en lumière des interactions entre le salaire minimum, la croissance économique et la pauvreté dans la société Antillo-guyanaise. Il s’avère que le dynamisme de l’économie insulaire est loin d’avoir gommé tous les écarts de niveau de vie entre les DFA et la France métropolitaine, malgré l’alignement du salaire minimum et des prestations diverses. La simulation sur les données de l’enquête Budget de famille 2006 montre que la proportion de salariés au SMIC est faible dans le bas de l’échelle des revenus. Ces salariés sont répartis sur l’ensemble de l’échelle des niveaux de vie. Le SMIC occupe une place relativement importante dans le revenu disponible des ménages, y compris dans le haut de l’échelle des revenus.En conclusion, le niveau élevé du salaire minimum dans les départements français d’Amérique conduit au maintien d’un grand nombre de salariés payés au voisinage du SMIC. En dépit des allègements de cotisations sociales abaissant le coût du SMIC, les départements d’outre-mer demeurent des régions fortement touchées par le chômage et la pauvreté. De plus, les inégalités salariales se sont accrues entre les individus les plus modestes et les plus aisés de ces régions. La montée du chômage est un facteur aggravant de cet accroissement des inégalités. Si en effet, les résultats de notre étude permettent d’affirmer que le SMIC n’est pas le meilleur instrument pour lutter contre les inégalités salariales et la pauvreté, ils soulèvent en même temps la question d’un SMIC DOM en lien avec les conditions et capacités réelles des économies ultramarines. / This work consists of three parts seeking to analyze the impact of minimum wages on the French departments of America's economy by limiting the effects on the distribution of incomes and economic growth.In the first chapter, the focus is an overview of income inequality as they exist in the Antilles and Guiana, in comparison with the situation in France. Income inequalities remain high between occupational groups in the DFA. The average salary of all employees in mainland France is higher than the DFAThe second chapter first presents the historical and regulatory aspects that characterize the French minimum wage and that of other European countries. SMIC is the fourth highest minimum wage in Europe, and France developed country with the highest proportion of employees the minimum wage. In the French Departments of America, employees paid the minimum wage, many more in proportion than at national level, are most often women, youth, low-skilled people employed part-time in the service sectors and trade. It also highlights the impact of the minimum wage and its revaluation on the formation of wages and labor costs. SMIC diffusion effects are small and temporary, varying from 0.1 to 0.2% in both macroeconomic and microeconomic approach. The increases in the minimum wage lead to higher labor costs partly offset by expense reductions granted to companies. The third chapter contributes to highlighting the interaction between the minimum wage, economic growth and poverty in the Antillean-Guyanese society. It turns out that the dynamism of the island economy has all but erased all living differentials between overseas departments and metropolitan France, despite the alignment of the minimum wage and various benefits. The simulation on data from the 2006 survey of “Budget of families” shows that the proportion of employees with the minimum wage is low in the bottom of the income scale. These employees are spread over the entire scale of living. SMIC has an important place in household disposable income, including the top of the income scale.In conclusion, the high level of the minimum wage in the French departments of America led to the maintenance of a large number of employees paid near the minimum wage. Despite cuts in social security contributions lowering the cost of SMIC, departments remain areas with high unemployment and poverty. Moreover, wage inequality increased between the poorest and the wealthiest individuals in these areas. Rising unemployment is an aggravating factor of the increase in inequality. Since the results of our study make it possible to affirm SMIC is not the best tool to fight again wage inequalities and poverty, they also raise the question of a SMIC DOM linked with the real conditions and capacities of the overseas economies.

Cette thèse étudie les déterminants de la localisation des emplois, des travailleurs et des entreprises en France. Le chapitre 1 évalue l’effet des Zones Franches Urbaines sur leurs habitants. Il montre d’une part que cette politique a réduit de manière significative le chômage des résidents, du fait notamment de la présence d’une clause d’embauche locale et, d’autre part, qu’elle a occasionné à long terme des effets de recomposition sociale des quartiers ciblés, dont elle a accru la part de travailleurs qualifiés. Le chapitre 2 mesure l’impact sur le management des entreprises du temps de trajet entre les filiales et leur siège social. Il montre que les filiales que le TGV a permis de relier plus rapidement à leur siège social ont réduit la proportion de managers dans leur main d’œuvre et se sont concentrées sur leurs activités de production. Le chapitre 3 décrit la baisse du salaire relatif des travailleurs qualifiés et l’augmentation parallèle de l’offre relative de travail qualifié qui s’est produite en France pour les hommes de 15 à 65 ans entre 1967 et 2009. Il montre que l’augmentation du niveau d’éducation a masqué une réorientation de la demande de travail vers les plus qualifiés d’une ampleur égale au moins à la moitié ce qui a été observé aux États-Unis. Une analyse complémentaire est ensuite conduite au niveau des marchés locaux du travail, afin de décrire les dynamiques spatiales de l’offre de travail et des inégalités de salaires par niveau d’éducation en France sur la période 1982-2011. Elle montre que les travailleurs les plus diplômés se sont concentrés géographiquement et que la demande de travailleurs qualifiés a évolué différemment suivant les territoires. Le chapitre 4 s’appuie sur les dynamiques spatiales des salaires et de l’offre et la demande de travail pour tester l’hypothèse selon laquelle le progrès technique et l’informatisation biaiserait la demande de travail vers les qualifiés. Plus précisément, il montre que les emplois routiniers ont plus décru dans les marchés du travail où leur part était initialement élevée, mais que les emplois abstraits n’y ont pas augmenté comme c’est le cas aux États-Unis. Il montre ensuite que l’effet des nouvelles technologies sur les emplois routiniers et abstraits varie avec le type de fonction occupée : support ou de production. / This thesis investigates the determinants of jobs’, workers’ and firms’ location decisions in France. The first chapter evaluates the impact of French enterprise zones on their residents. It shows that this program reduced significantly the unemployment rate of residents due, in part, to the fact that firms’ payroll exemptions were made conditional on local hiring. It also shows that social composition effects occurred in the long run, and that the program increased the share of high-skilled workers in enterprise zones. The second chapter documents the impact of rail travel time on the management of French multi-plant businesses. It shows that affiliates which benefited from new High Speed Rail lines to relate faster to their headquarters reorganized and decreased the share of managers in the workforce, while refocusing on their production activity. The third chapter documents a strong decrease in the high-skilled/low-skilled relative wage that occurred concomitantly with a strong increase in the relative labor supply for male aged 15-65 in France in the last 40 years. It shows that the increase in educational attainment has hidden the effects of a skill-biased demand shift, which are found to be of at least half of those found in the U.S. An additional analysis is conducted at the level of local labor markets. It investigates the spatial trends of education supply and wage inequalities by education levels and shows that a spatial concentration of educated workers and a skill-biased spatial shift in demand occurred in France between 1982 and 2011. The fourth chapter uses the spatial dynamics of wage, labor supply and labor demand to test the “computerization” hypothesis for France on the period 1990-2011. It shows that jobs with codifiable or routine tasks declined more on the labor markets where their share in employment was initially higher, but that abstract jobs did not increase in the same places, like in the US. It then shows that skill-biased technical change affects the spatial distribution of routine and abstract jobs according to the function performed: support or production.

This thesis consists of three self-contained essays about immigrants’ experiences in Sweden. They all focus on the interaction between institutional settings and effects on immigrants’ economic conditions. Essay I examines the effects of changed eligibility rules for disability pension in the 1979 Swedish pension reform on immigrant retirement behavior. The reform made disability pension in the form of basic pension available to a wider group of immigrants. Before the pension reform, the eligibility for a basic pension for foreign citizens living in Sweden was dependent on bilateral and multilateral agreements on social security between Sweden and other countries. Thus, immigrants who were not covered by any of these agreements had no access to a basic pension before the reform. Through the reform, all foreign citizens residing in Sweden were made eligible for a basic pension after a short qualification period. The results indicate a substantial impact on the retirement rate with disability pension on the immigrant group that was made eligible for a basic pension by the reform. These findings confirm previous research showing that the size of the benefit levels in the pension system affects early retirement behavior. Essay II analyzes the impact of the Swedish taxi and bus deregulations on the differences in labor earnings between Swedish born and foreign born workers in these sectors. The changes in the gap in labor earnings that are due to the deregulation are estimated. The results show that there was no significant decrease in the differences in labor earnings between Swedish born and foreign born workers in the bus sector as a result of the 1989 deregulation. As regards the taxi sector, the results show that, before the deregulation, there were only small differences in labor earnings between Swedish born and foreign born workers. After the deregulation, the real labor earnings of foreign born workers decreased substantially more than those of Swedish born workers. However, there was a larger increase in the inflow of foreign born workers than of Swedish born workers into the taxi sector after the deregulation, which may have changed the composition of immigrant workers in this sector. Essay III investigates the impact of becoming a Swedish citizen on annual labor earnings. The study finds a positive impact of naturalization on labor earnings, in particular for immigrants originating from Africa and Asia, an effect than cannot only be attributed to selection into citizenship. A clear trend of increasing labor earnings during the years before becoming a Swedish citizen is found. This trend also continued during the years after citizenship acquisition. The study also suggests that the effects of naturalization on labor earnings are larger for men than for women, and larger for individuals with very low income.

The theme of this thesis is "Distributional and redistributional processes in the Czech Republic". The aim of this thesis is to analyze incomes of Czech households in relation to flows related to the services of factors of production, and consequently, in response to the inequality, to examine redistributional processes that shape the final income of these households. The thesis is divided into three parts. The first part is devoted to literature search. There are explained basic concepts related to incomes of households, inequalities in income distribution and distributional and redistributional processes. There is also described the principle of social insurance, state social support and social assistance. The second part contains a description of the aim and methodology of this thesis. The third part of this thesis is the practical part. There is described structure and development of incomes of Czech households, state expenses on welfare benefits and there are evaluated income inequality and redistributional processes in the Czech Republic. On the basis of evaluated data, it is confirmed that among Czech households there is a specific degree of income inequality, but in comparison to other EU countries is this inequality one of the lowest. Income inequality is caused mainly wage inequalities. The aim of the state in the redistributional processes and the provision of welfare benefits is in particular to direct welfare benefits to people who need them the most and thus reduce income inequalities in society. On the basis of evaluated data and performed analysis in this thesis, it was found out that this assumption is fulfilled in the Czech Republic.
