Economic participation of women in the labour force or as entrepreneurs is low compared to peers and has declined over the past decades despite strong growth. The gap with men is over 50%--the largest among key emerging markets. Participation declines with higher education achievements and family incomes. The reasons are complex: socioeconomic and cultural factors are important - family status increases if women stay home, house work has become more attractive than poorly paid market work as husband’s incomes have risen; and safety concerns and poor infrastructure keep women from market work. Nevertheless, high unemployment among educated women and revealed preference for work in surveys indicate that many women would work if conditions improved. Availability of jobs is also an issue as the high growth has not created enough jobs for men and especially for women. Specific gender policies will be needed to enlarge economic opportunities for women and to overcome socioeconomic and cultural barriers. This paper analyses the determinants of low female economic participation and recommends policies for raising it. The paper also estimates long-term growth effects of raising participation with selected policies. More and better jobs for women in India could raise growth by about 2 percentage points a year over time. This Working Paper relates to the 2014 OECD Economic Survey of India (http://www.oecd.org/eco/surveys/economic-survey-india.htm).
