What we have done on foreign brides income:
1. Foreign Spouses Survey: It only asked for the sources of income, but didn’t ask for the amount of income.
2. Survey of Family Income and Expenditure: This survey didn’t ask for nationality after 1993. Therefore, we used the sample of all married women to approximate income level of the local, considering that the proportion of foreign brides is relatively small.
3. Chen’s paper: The author didn’t reply to our request for micro data.
