Stratégies De Recherche, Contraintes Spatiales Et Hétérogénéité Des Transitions Vers L’Emploi : Estimation Économétrique D’Un Modèle Structurel De Recherche[Job search strategies, spatial constraints and unemployment duration]

This paper provides new developments in job search theory, incorporating a duality in search strategies which compose the offer rate. Two strategies are modelled. A first one, called passive strategy, consists in searching exclusively in the spatial area of the public employment agency. The alternative strategy allows to extend search area, using other media, like networks or advertisements. Introducing this duality leads us to ambiguous effects of search strategies on the theoretical exit rate. A micro-econometric estimation allows us to overcome this difficulty. A two-step method is chosen in order to, first, study the strategies’ selection rule and, second, to take into account multiple destinations after unemployment and possible unobserved heterogeneity in the duration model. Results highlight the selectivity of the search strategies’ choice, in particular the role of spatial constraints. Besides, they conclude to discriminate impacts of job search strategies on exit rates, according to the job found.
