Excerpt: This paper applies structural models of retirement and saving of two earner couples to explore the effects on retirement of two actuarially neutral policies, which we know from previous work can have a substantial effect on retirement if heterogeneity in time preference rates is allowed. The main question being investigated here is whether using a model that explicitly incorporates the retirement interactions of two working spouses yields a different evaluation of policies than when a much simpler model that treats the retirement decisions of the second spouse as exogenous is used.
