We estimate an agency model using the payroll records of a copper mine that paid a production bonus to teams of workers. We estimate the cost of incomplete information due to insurance and incentives considerations and the inefficiency caused by the simple form of the incentive contract itself. At the estimated parameters the cost of worker risk aversion (insurance) is of similar magnitude to moral hazard (incentives). Overall, incomplete information accounted for one-half of the bonus system's inefficiency relative to potential full information profits. The other half is attributed to the bonus system's inefficient generation of incentives and insurance relative to the optimal incentive contract.

À partir des cohortes de l'Enquête nationale auprès des diplômés, nous analysons les revenus des Canadiens détenteurs d'un baccalauréat cinq ans après l'obtention de leur diplôme. Nos résultats montrent qu'il y a un lien important entre les revenus et l'université qui décerne le diplôme, puisque nous observons des corrélations entre les revenus et les caractéristiques des universités fréquentées. Par exemple, le nombre plus élevé d'étudiants de premier cycle, qui entraîne possiblement un enseignement de qualité moins élevée, est lié à des revenus inférieurs. Chez les hommes, mais pas chez les femmes, un ratio professeurs-étudiants plus élevé est lié à des revenus significativement plus élevés. Quand on ne tient pas compte de la majeure des étudiants, qui peut être liée de façon endogène à l'université fréquentée, l'effet des caractéristiques des universités est encore plus marqué. Notons toutefois que les caractéristiques des universités ne sont pas fortement liées à la probabilité d'obtenir un emploi après l'obtention d'un diplôme. Mots clés : enseignement supérieur, capital humain, revenus sur le marché du travail Using three cohorts of the National Graduates Survey, we study earnings five years after graduation from Canadian bachelor's programs. Evidence is found of significant university-specific effects on earnings. Changes in earnings and university characteristics across cohort are correlated. Increased undergraduate enrolment is associated with lower earnings, suggesting crowding out in educational quality. For men, but not women, increases in the professor-student ratio are associated with meaningful gains in earnings. When student major is excluded, since it may be endogenous to university, the effect of university characteristics is much larger. University characteristics are not strongly related to post-graduation employment probabilities.

Terms of use: Documents in Abstract:This paper models the Self-Sufficiency Project (SSP), a controlled randomized experiment concerning welfare. The model of household behavior includes stochastic labor market skill, job opportunities, and value of non-labor market time. All the variation within and between treatment groups, jurisdictions (provinces), demographic groups, and sub-experiments is derived from four underlying sources: policy variation, endogenous selection into the experimental samples, the SSP treatments themselves, and different mixtures over 4 underlying types. Using the variation within the treatment group is quantitatively important for identifying the complex model: Efficient GMM the parameters are estimated precisely and variation within the treatment group is much more important for identification than either variation within the control group or between treatment and control groups. The model tracks the primary moments well within sample and out-ofsample except for under-estimating the difference in the entry sample. Predictions of the estimated model are computed for different welfare reform experiments. The details of the design are critical for interpretation of the results and it appears that the small SSP+ treatment may have longer lasting impacts than the an in-sample impact analysis would suggest.JEL Classification: I3, C9, J0, C5
