This paper presents an analysis of the gender wage gap in the highly regulated Australian labour market. It compares wage outcomes in the wage and salary sector with those for the self-employed. Comparisons with the United States are provided. The large gender pay gap in self-employment suggests that the aggregate gender wage differential will not be eliminated solely through wage determination for wage and salary earners. The greater gender wage gap in the self-employed sector may reflect liquidity constraints that are more difficult for self-employed women to overcome relative to self-employed men. The comparisons with the United States suggest that women will experience deterioration in relative earnings as the Australian labour market is deregulated.
