Largely seen as a boon for industrial society, women in the workforce contribute to a higher national economic output as measure in GDP as well as decreasing labor costs by increasing the labor supply in a society. [...] History [edit]U-shaped curve [edit]Claudia Goldin described women's participation rate in the workforce as a U-shaped curve. One that as a country develops, women's participation rate in the workforce starts high, declines, and then rises again. Its decline starts from a move from production in the household, family farm, or small business to a wider market. A strong social stigma of women working in paid manual labor outside of the home, not only in male-dominated industries, but also female-dominated industries such as textiles. Such stigma includes that only a lazy man (or of low social status/income) who neglects his family would let his wife do manual labor. The participation rate of women falls as the income rises, which even includes an increase in income for women's labor. Participation begins to rise once women's education improves and the value of women's time increases relative to the price of goods.[94] [...] Women's participation in different occupations [edit]Below is a sample of encyclopedia articles that detail women's historical involvement in various occupations.
