    The financial crisis has resulted in a substantial increase in unemployment in the OECD. This paper shows that this increase has reversed the reduction in structural unemployment which has been estimated to have occurred in most OECD countries since the late 1990s. Structural unemployment is defined as a time-varying NAIRU derived from the information contained in a reduced Phillips curve equation (linking inflation to the unemployment gap) by means of a Kalman filter. The overall limited revisions in historical NAIRU estimated in 2008 after such a large labour market shock support the robustness of the OECD approach. This approach is therefore extended to almost all OECD countries. Alternative specifications of the Phillips curve are proposed for some specific groups of countries. Un réexamen des NAIRUs après la crise La crise de la crise financière a entraîné une augmentation importante du chômage dans l'OCDE. Ce document montre que cette augmentation a inversé la tendance á la réduction du chômage structurel que l’on avait été estimé avoir eu lieu dans la plupart des pays de l'OCDE depuis la fin des années 1990. Le chômage structurel est défini comme à un NAIRU variant dans le temps et dérivé de l'information contenue dans une équation de courbe de Phillips réduite (reliant l'inflation à l'écart du chômage au chômage structurel) au moyen d'un filtre de Kalman. Les révisions dans l’ensemble limitées du NAIRU historique estimés en 2008 après un tel choc sur le marché du travail supportent la robustesse de l'approche de l'OCDE. Cette approche est donc étendue à presque tous les pays de l'OCDE. Des spécifications alternatives de la courbe de Phillips sont proposées pour certains groupes spécifiques du pays.
