I am planning a cross-cultural study that includes developed and developing countries. My research questions deal with the effects of the provision of care for labour market participation. Typically, the provision of care is studied in developed countries using Esping-Andersen’s typology and in developing countries using variations of Evers et al (1994) or Razavi 2007 “care diamond”. The Esping-Andersen typology is a poor choice for developing countries but the concept of a care diamond could be an appropriate concept in both developed and developing countries. I am looking for advice about the feasibility of this approach. References on the subject would also be appreciated.
