Réglementation et avenir du travail: la relation de travail facilite l'innovation

La transformation numérique et la réorganisation des entreprises font apparaître de nouvelles modalités de travail fort éloignées de la relation de travail typique. Selon les partisans de la rupture numérique, le cadre juridique actuel n'est pas adapté aux formes de travail et modèles d'entreprises «innovants». Pourtant, la réglementation du travail peut faciliter l'innovation et la flexibilité, comme l'emploi typique peut être un moyen d'améliorer l'efficacité et de réduire les coûts. En effet, la relation de travail permet le plein exercice des prérogatives de l'employeur et le déploiement interne de la main-d'œuvre; c'est aussi un bon moyen d'assurer formation et montée des compétences.     

RISK PREFERENCES AND EXPECTED UTILITY: EVIDENCE FROM LABOR SUPPLY DATA

This paper adds to the growing body of evidence that observed risk preferences are not consistent with expected‐utility theory. Using the link between labor supply decisions and utility as outlined by Chetty (“A Bound on Risk Aversion Using Labor Supply Elasticities.” The American Economic Review, 96(5), 2006, 1821–34), I compute the curvature of utility over wealth for 3,900 individuals in the 1996 Panel Study of Income Dynamics. I then compare this estimate to a measure of relative risk aversion based on the respondents' answers to hypothetical gambling questions and find virtually zero correlation. Finally, I investigate how the two measures and their correlations change by demographic groups and risky behavior. (JEL C81, D80, J22)     

YOUR RIGHT ARM FOR A PUBLICATION IN AER?

The time tradeoff (TTO) method is popular in medical decision making for valuing health states. We use it to elicit economists' preferences for publishing in top economic journals and for living without limbs. The economists value journal publications highly and have a clear preference among them, with the American Economic Review (AER) the most preferred. Their responses imply they would sacrifice more than half a thumb for an AER publication. These TTO results are consistent with ranking and willingness to pay results, and indicate that journal preferences are not entirely determined by impact factors or by expectations of a salary increase following a publication in a prestigious journal. (JEL A10, B41, I10)     

Nonresponse Bias for Attitude Questions

By separating respondents in a survey of farmers into thosewho refused to be interviewed and were converted, those whowere hard to reach, and those who gave no problems, we can estimatenonresponse bias from refusers not converted and respondentsnot reached. We show that for attitude questions the refusalbias is serious, ranging from 2 to 4 percent on many attitudes,and very often larger than the standard error in surveys ofordinary size.
