This paper investigates how individuals make educational choices in situations where some education sectors present the risk of ending up being overcrowded. We report on an entry-game experiment whose aim is the production of data controlled in order to test the cliometric model of glutting developed by Diebolt [2001. "La théorie de l'engorgement. Economie Appliquée" 54 (4): 7-31], and especially the sensitivity of men and women to expected wages and to the risk as related to a limited number of positions on the labor market.
