On the upside, Goldin (2006) showed that women adapted rapidly over the 20^th century to changing returns to working and education as compared to options outside the market. Their labour force participation and occupational choices changed rapidly into long duration professional educations and more specialised training in the 1960s and 1970s as many more women worked and pursued careers. The large increase in tertiary education by New Zealand after 1990 and their move into many traditionally male occupations is another example.

The key is what drives the rapid changes in the labour force participation and occupational choices of women. Some of the factors are global technology trends such rising wages and the emergence of household technologies and safe contraception and antidiscrimination laws. All of these increased the returns to working and investing in specialised education and training.

Up until the mid-20^th century, women invested in becoming a teacher, nurse, librarian or secretary because these skills were general and did not deprecate as much during breaks. When expectations among women of still working at the age of 35 doubled, there were massive increases in female labour force participation and female investments in higher education and specialised skills (Goldin and Katz 2006). These trends continue to today.

Women and in particular those women making education choices need good information on their prospects in different occupations. The evidence is they adapt rapidly to changing prospects (Goldin 2004, 2006). Goldin (2004, 2006) referred to a quiet revolution in women’s employment, earnings and education because the changes in female labour supply and occupational choices were abrupt and large.

Women adapted rapidly to changes in their expectations about their future working life, graduation rates, attainment of professional degrees, age of first marriage, and the timing and number of children. These expectations of women about their futures turned out the surprisingly accurate (Katz 2004, 2006). Young women are surprisingly good forecasters of their labour market involvement. Any gender policy options must be sensitive to the high level of responsiveness of women to changing educational opportunities and prospects and their precision to date as forecasters.

The complex decisions youth make about education and occupational choices is driven by many sources. Women are interested in issues that are of less importance to men such as work-life balance and the costs of career breaks to their earning power and human capital. Goldin (2004, 2006) argued that women who have a more accurate assessment of their future labour market involvement will invest more wisely in education and occupational choice.

The market process rewards the skills and commitment the men and women bring to the labour market. The differences in skills and commitment the men and women bring arise from a gendered division of labour and effort in the household and in raising families that appears to be open to only minor changes that are expensive in terms of growth and prosperity. This is because most gains in the status of women were the result of economic growth rather than legal interventions. Child care subsidies and parental leave arose after rising income made them and the modern welfare state fiscally affordable rather than the other way around.
