Over past week I came across an interesting report published by Booz & Company titled "Empowering the Third Billion Women". The following graph shows the increase in GDP if women participation in the labor force increases.
In the graph lower contribution would imply that women are participating in labor force and contributing to the national income. These are basically countries which are developed (Sweden, German, USA, U.K. etc). The curious case is that of Tanzania as it places itself among these developed economies . The main reason behind this is that women participation in agricultural sector is higher, but they are underpaid . On the other hand India has very low women participation , pointed out by the report, as they do not reach their full potential due to discrimination at work place and cultural reasons.
