A time series model of fertility and female labour supply in the UK

Multiple time series procedures suitable for estimation and testing with nonstationary data are applied to UK data on age-specific fertility rates, age-specific female labour force participation rates, and women's and men's wages. Cointegration tests establish the existence of two long-run equilibrium relations, identified as a fertility relation and a labour supply equation, for each age group. Maximum likelihood estimates of these equations are consistent with the new home economics model of fertility, and tests of Granger-causality show evidence of extensive feedback among the variables.
