The main objective of this paper is to develop a new system of national income accounting that better reflects women’s contribution to the national income. New methodologies are developed to decompose conventional GDP. The methods are then applied to the case of Bangladesh using nationally representative data on time allocation of men and women. The paper concludes that a more realistic estimation of GDP will be achieved only if women’s and men’s non-market work is accounted for-this methodology yields a GDP figure that is 29 per cent higher than conventional estimates, and it shows that women conventional estimates, and it shows that women contribute 41 per cent to total GDP.
