Strategies D'Insertion Et Duree D'Acces Au Premier Emploi[Job search strategies and unemployment duration before the first job]

This paper aims at estimating the impact of search strategies (effort and search channels) on unemployment duration. A two-step microeconometric application is used. First, the choice process of search strategies (number and type of search media used) is analysed. Second, competing risk models are estimated in order to evaluate the compared efficiency of search strategies. Results conclude to the endogeneity of the search strategies choice and to strong impacts of effort and search media on the first job access duration, according to the type of job found. This article proposes an interpretation of the firm as a bundle of interacting communities, in the perspective of the knowledge-based economy. It focuses on the examination of the forms of voluntary co-operative exchange in the communities and the emergence of collective beliefs and corporate culture. Thus, the particular analysis of the community level, by bringing additional dimensions of creation, validation and diffusion of knowledge, is a complement to the traditional modes of co-ordination of the firm.
