Pre-print, Working paper: This paper challenges the conventional wisdom that the dynamism of employment is always contradictory to the enforcement of some forms of security for workers. Contemporary theorizing now recognizes the specificity of the wage-labour nexus. Consequently, minimum security is required for good economic performance by firms and national economies. A comparative analysis of OECD countries shows that the extended security promoted by welfare systems has not been detrimental to innovation, growth and job creation. Developing countries cannot immediately catch up with the emerging standards of flexicurity but the methodology of employment diagnosis might help them in designing security/flexibility configurations tailored according to their domestic economic specialization, social values and political choices.
