Cahier du LEF ; 2008-05Cet article a été présenté dans plusieurs conférences sous le titre : Ambiguity, Government Intervention and Inusrance Decision : an Experimental Study ; This article presents the results of an experiment designed to test theoretical predictions about the impact of public compensation schemes and ambiguity on insurance and self-insurance decisions. Consistent with theory, we find that government assistance significantly reduceswillingness to pay (WTP) for insurance and self-insurance (compared with a free insurance market). As expected, we also find significant differences between WTPs for insurance under different types of government compensation programs. For example, results from our experiment confirm the prediction that the WTP for insurance is smaller under a "Fixed Help" program thanunder a "Contingent Fixed Help" program where the government assistance is conditioned to the purchase of an insurance policy. Thirdly, we find that ambiguity, i.e., uncertainty about probability, significantly increases WTPs for insurance. This result, which indicates thatdecision-makers are ambiguity averse, is in line with previous results on the impact of ambiguity on insurance demand for low probability risks. Lastly, our experiment provides a clear support for the hypothesis that attitude to risk and attitude to ambiguity are two independent phenomena. In fact in this experiment, decision-makers are both risk-seekers (i.e., the mean WTP for insurance is on average smaller than the expected value of the loss) and ambiguity averse (i.e., the mean WTP for insurance is on average higher for an ambiguous risk than for a 'risky' risk) ; Cet article présente les résultats d'une expérience mise en place pour tester des prédictions théoriques concernant l'impact de programmes publics de compensations financières et de l'ambiguïté sur les décisions d'assurance et d'auto-assurance. En conformité avec la théorie, nous montrons que l'aide du gouvernement réduit significativement le consentement à payer (CAP) ...

This article analyses the role of academics in the production and maintenance of alternative organizations within the capitalist system. Empirically, we focus on academics from the University of Buenos Aires who, through the extension programme Facultad Abierta, have supported worker-recuperated enterprises since their emergence in Argentina in the early 2000s. Conceptually, we build on prior studies on worker-recuperated enterprises as well as the 'critical performativity' concept that we define as scholars' subversive interventions that can involve the production of new subjectivities, the constitution of new organizational models and/or the bridging of these models to current social movements. Our results uncover the multiple roles of academics in relation to these three facets and highlight the key interactions of these roles. In so doing, our analysis advances prior studies of worker-recuperated enterprises by clarifying how academics can support alternative organizations while offering a renewed conceptualization of critical performativity as a multifaceted process through which academics and workers interact.
