Pourquoi les docteurs s’insèrent moins bien que les ingénieurs, et que faire?
This paper studies why PhDs in France have more difficulty entering the job market than engineers. Using data from CEREQ’s “Génération 2004” survey, we show that job finding rates of PhDs are lower than those of engineers and situate them among post-secondary graduates as a whole. We show that this phenomenon holds even when restricting attention to R & D jobs, and that the difference is mainly due to differences in the fields of study of PhDs and engineers. We also show that the relative demand for PhDs is only moderately sensitive to cost, as only the large employment subsidies inherent in the most recent reform of the “dispositif jeunes docteurs” of France’s research tax credit were able to significantly improve placement of young PhDs.

Inventory Management with Carryover in a Laboratory Setting: Going Beyond the Newsvendor Paradigm
écrit avec Charles A. Holt (University of Virginia)
Abstract.
This paper considers a stationary model of inventory management in a rich setting in which unsold units carry over, in contrast with the full depreciation of unsold units that is implemented in laboratory studies of the newsvendor problem. The model permits an array of costs associated with restocking, understocking, depreciation, financing, and holding inventories. The extra dimensions make it possible to hold the optimal inventory constant, while adjusting parameters that change the frequency of stockouts and the risk associated with storage and depreciation. This framework facilitates an investigation of factors that influence the nature and severity of behavioral biases observed in simpler newsvendor settings. Optimal inventory decisions are derived and tested with a laboratory experiment. We consider four main questions in the inventory literature: the “pull-to-center” effect, the “recency” effect, the effect of increased up-front costs, and the effect of risk aversion.
