We critique and investigate the popular structure that simply assumes that workers with different age, experience or education are perfectly substitutable in production. This structure is inconsistent with empirical evidence of production complementarities. We couch our findings in the context of two types of policy reforms: a social security reform and a tax reform. These reforms were chosen in part not only because of the large interest in them, but also because of their differing effects on life cycle decisions. We find that ignoring production complementarity may influence the conclusions of policy analysis.en-USThis Item is protected by copyright and/or related rights.
