Womenomics and Opportunity Costs

"A report this week by the United Nations Economic and Social Commission for Asia and the Pacific concludes that sex discrimination costs the region $42 billion-47 billion a year by restricting women's job opportunities. A gap of 30-40 percentage points between men's and women's workforce participation rates is common. The poor state of girls' education costs a further $16 billion-30 billion. And those are just the economic costs, before violence against women and access to health care are counted."
