One strand of the literature claims that the labour force participation of migrant women is influenced by their ethnic background. Another strand of the literature claims that the rise in female labour force participation results from changes in culture within a particular country. The current study combines the two approaches by investigating the differential impact of home and host-country participation on the participation of migrant women in the Netherlands. Home-country labour market participation represents home-country culture, while the strong increase in the participation rate of native women over birth cohorts represents developments in host-country culture. Evidence from the Dutch labour force survey 1996-2007 suggests that home-country participation matters for the first generation, but not for the second generation. The change in host-country participation over birth cohorts affects the participation of migrant women as well. Our results suggest that culture is not a static phenomenon. Participation behaviour of migrant women moves together with the behaviour of native women.
