Public pension programmes and the retirement of married couples in Denmark

In this paper we study the economic determinants of the joint retirement process of married couples. We propose a tractable dynamic discrete choice model for retirement decisions which allows for non-trivial saving behaviour. We estimate the model on a 1% sample of Danish couples of potential retirement age drawn from a population-based administrative register. The introduction and subsequent reforms of a publicly financed early retirement programme provide us with variation in the data to insure identification of the parameters of interest: the elasticities of participation/retirement with respect to income flows. Our estimates imply a significant asymmetry in the sensitivity of retirement behaviour of men and women with respect to variation in their own, or their spouse's, income flows.
