L’essence de la théorie du capital humain (Becker, 1964) prédit que l’investissement dans les activités visant à renforcer le potentiel productif des individus se traduit par une augmentation de leurs revenus tout au long de leur carrière (Benjamin, Gunderson et Riddell, 2002 : 245). Pour le groupe occupationnel constitué par les artistes, la littérature s’accorde pourtant pour dire que l’investissement en capital humain demeure rentable financièrement, mais à un niveau sensiblement moindre que pour les autres professions (Snooks, 1983; Filer, 1990; Rengers, 2002; Alper et Wassall, 2006). Nous exposons les théories du capital humain, des différences de salaire compensatoires (Smith, 1776) ainsi que la théorie hédonique des salaires (Rosen, 1974; Rosen et Thaler, 1975) afin d’atteindre deux objectifs. Premièrement, nous cherchons à vérifier empiriquement l’impact de l’acquisition de capital humain sur le revenu d’emploi autonome des artistes canadiens . Dans une autre perspective, nous souhaitons également évaluer la nature et la taille du différentiel de revenu d’emploi par rapport aux autres professions et investiguer les facteurs sur lesquels il repose. Le projet comble un vide dans la littérature portant sur les déterminants du revenu d’emploi des artistes canadiens et permet de réfléchir à l’orientation des politiques publiques culturelles entourant la formation académique de ceux-ci. Nous employons une analyse de régression multivariée sur des variables de capital humain en ayant recours aux données du recensement canadien de 2006 . Plus précisément, nous tentons de mesurer la relation associative entre le revenu de travail autonome exprimé sous forme de logarithme du salaire hebdomaire des artistes canadiens et la scolarité, l’expérience de travail, le sexe, le statut marital légal, la profession/spécialité artistique (classification selon la CNP-S, en vigueur en 2006), le statut d’immigrant, le statut de minorité visible, le fait d’être le principal soutien de la famille ainsi que la zone de résidence. Les résultats nous apprennent que la scolarité demeure rentable financièrement pour la majorité des spécialités artistiques, mais que des profils de scolarité précis ont avantage à être privilégiés selon la spécialité artistique. L’expérience de travail s’avère quant à elle moins rentable au niveau de la rémunération que chez les autres professions, tout comme elle est moins avantageuse financière pour les artistes issus des arts performatifs chez qui la carrière se termine habituellement assez tôt. En ce qui concerne l’effet des variables sociodémographiques, soulignons seulement que le fait d’être de sexe masculin est associé à de plus hauts revenus chez les artistes, mais dans une proportion moindre que chez les autres professions. Quant aux effets des statuts d’immigrant et de minorité visible sur le revenu d’emploi, ceux-ci varient mais demeurent moins pénalisants chez les artistes, ce qui suggère que le marché du travail culturel serait moins discriminant que le marché du travail traditionnel.

This paper analyzes the dynamics of wages and workers' mobility within firms with a hierarchical structure of job levels. The theoretical model proposed by Gibbons and Waldman (1999), that combines the notions of human capital accumulation, job rank assignments based on comparative advantage and learning about workers' abilities, is implemented empirically to measure the importance of these elements in explaining the wage policy of firms. Survey data from the GSOEP (German Socio-Economic Panel) are used to draw conclusions on the common features characterizing the wage policy of firms from a large sample of firms. The GSOEP survey also provides information on the worker's rank within his firm which is usually not available in other surveys. The results are consistent with non-random selection of workers onto the rungs of a job ladder. There is no direct evidence of learning about workers' unobserved abilities but the analysis reveals that unmeasured ability is an important factor driving wage dynamics. Finally, job rank effects remain significant even after controlling for measured and unmeasured characteristics.

This article studies mobility patterns of German workers in light of a model of sector-specific human capital. Furthermore, I employ and describe little-used data on continuous on-the-job training occurring after apprenticeships. Results are presented describing the incidence and duration of continuous training. Continuous training is quite common, despite the high incidence of apprenticeships which precedes this part of a worker's career. Most previous studies have only distinguished between firm-specific and general human capital, usually concluding that training was general. Inconsistent with those conclusions, I show that German men are more likely to find a job within the same sector if they have received continuous training in that sector. These results are similar to those obtained for young U.S. workers, and suggest that sector-specific capital is an important feature of very different labor markets. In addition, they suggest that the observed effect of training on mobility is sensible to the state of the business cycle, indicating a more complex interaction between supply and demand that most theoretical models allow for.

Using data from the National Longitudinal Survey of Youth (NLSY), we re-examine the effect of formal on-the-job training on mobility patterns of young American workers. By employing parametric duration models, we evaluate the economic impact of training on productive time with an employer. Confirming previous studies, we find a positive and statistically significant impact of formal on-the-job training on tenure with the employer providing the training. However, the expected net duration of the time spent in the training program is generally not significantly increased. We proceed to document and analyze intra-sectoral and cross-sectoral mobility patterns in order to infer whether training provides firm-specific, industry-specific, or general human capital. The econometric analysis rejects a sequential model of job separation in favor of a competing risks specification. We find significant evidence for the industry-specificity of training. The probability of sectoral mobility upon job separation decreases with training received in the current industry, whether with the last employer or previous employers, and employment attachment increases with on-the-job training. These results are robust to a number of variations on the base model.

The following properties of the core of a one well-known: (i) the core is non-empty; (ii) the core is a lattice; and (iii) the set of unmatched agents is identical for any two matchings belonging to the core. The literature on two-sided matching focuses almost exclusively on the core and studies extensively its properties. Our main result is the following characterization of (von Neumann-Morgenstern) stable sets in one-to-one matching problem only if it is a maximal set satisfying the following properties : (a) the core is a subset of the set; (b) the set is a lattice; (c) the set of unmatched agents is identical for any two matchings belonging to the set. Furthermore, a set is a stable set if it is the unique maximal set satisfying properties (a), (b) and (c). We also show that our main result does not extend from one-to-one matching problems to many-to-one matching problems.
