Notes: For panel A, notes from Tables 5 and 6 apply. Each column is a separate specification. Part-time and self-employed come from different questions and are not mutually exclusive. Part-time and self-employment status are based on current employment only. In panel B, each row reports results from two separate regressions for log average hourly wages, for 50- to 59-year-olds or 60- to 69-year-olds.
