The study highlights the contribution of working women (in the age group of 16-60 years) in their household budget. These women are involved in informal economy. Employing the OLS model on 1780 observations it is found that women as head of household, women=s education, ownership of assets by woman have positive effect on their contribution. Age of the woman has a non-linear effect. First the contribution increases and then decreases by increase in age of the woman. Married women contribute more to household budget.
