This paper analyzes part-time employment and moonlighting in the United States for 1964-93. Consistent with previous research, I find a steady trend up in the rate of part-time employment for men during the 1960s and 1970s. Contrary to common perception, however, the rate has been roughly constant since the early 1980s. Female part-time employment has decreased since the early 1980s. I also show evidence on convergence in the work patterns of men and women: the rapid increase in moonlighting for college-educated women in recent years further highlights the diminished importance of gender and increased role of education in explaining labor market behavior.
