This thesis is about the determination of women’s labour supply in Bangladesh and Pakistan from 1980 to 2011. The study focuses on the demographic variables (infant mortality rate and total fertility rate), primary education rate, GGDP per capita growth and GGDP per capita growth square. The VEC model is used to estimate the relationship between variables, in the long run. Data are obtained from the World Bank. The results for both countries confirm the U-shaped pattern hypothesis between women’s labour supply and economic development. The results indicate that, in Bangladesh, a shock to infant mortality rate on women’s labour supply is more effective than in Pakistan, and that a positive shock to primary education on women’s labour supply is more effective in Bangladesh than in Pakistan. The results also show that a positive shock to total fertility rate on women’s labour supply in both countries has a similar impact
