Workers with longer job tenure are paid more, on average, than those with shorter tenure. This paper re-opens the debate about whether individual financial returns to tenure are due to firm-specific human capital accumulation or sorting according to unobserved individual productivity heterogeneity. We construct worker-firm employment histories 1964-1998 for all residents of Denmark and link this to wage and demographic information for all private sector workers 1980-1998. All firm closures are observed, and following Kletzer (1989) we exploit these exogenous worker displacements from larger firms to distinguish between firm-specific human capital and worker heterogeneity. Although the proportion of tenure returns due to firm-specific human capital is smaller than that found in the US, it has increased from 10% in 1980 to 30% in 1998 in Denmark. This change coincides with decentralisation of the wage bargaining process and may be explained by the increased freedom to write individual contracts.
