Match income variables from BHPS to UndSoc
I'm working with the BHPS and UndSoc and would like to create consistent income measures for the same underlying BHPS population extended to UndSoc. I'm interested in annual gross and net household income and, if possible, net disposable income. Can the variables wFIHHYR, wFIHHYL, FIHHYNL, wFIHHYI in the BHPS matched to ones in UndSoc? There is only fihhmngrs_dv (gross monthly HH income) and hhnetinc1 (total net HH income), but upon closer inspection these variables display huge discontinuities across the different panels for the same individuals and households. To rule out changes in household composition I also looked at individual level income, but again there are discontinuities. Any help on how to find consistent income variables without breaches would be appreciated.
