They would also like to acknowledge the participants in the FERDI International conference on "International labour mobility and inequality across nations" (Clermont-Ferrand, January 2014) and to the expert meeting on "Harnessing knowledge on the migration of highly skilled women" co-organised by the International Organization for Migration and the OECD Development Centre (Geneva, April 2014). The push and pull factors influencing this significant share of migration have typically been explained as a by-product of male migration: female migrants have been assumed to migrate mainly for reasons of family reunification as dependents of male migrants as wives, daughters or mothers. Over the years, the body of knowledge on the migration of women seeking better employment opportunities has increased, including research on topics such the role of gender discrimination in the workplace.
