We find strikingly similar and relatively low wage elasticities across countries, but greater elasticities for job security, as measured by contract type. We provide suggestive evidence that the similarity of our wage elasticities and the greater sensitivity of job security to labor market concentration may be explained by the fact that sector-level collective bargaining is dominant in the countries we study and that it sets wages but usually not contract type.371196146engEconomics and EconometricsStrategy and ManagementOrganizational Behavior and Human Resource ManagementManagement of Technology and Innovationjournal article10.3368/jhr.0223-12757R1https://www.scopus.com/pages/publications/105039998590
