Development Accounting
Development accounting is the manipulation of a production function to examine whether cross-country income differences arise from differences in total factor productivity (TFP), or due to factor accumulation. It is useful to find this information out so that we can correctly inform policy decisions and let developing countries know if they need to simply increase quantity of factors of production (i.e. promote higher fertility, immigration, labour market inclusion and capital appreciation), whether they need to increase the quality of the factors of production (better education and more efficient use of investment funds) or if they need to increase efficiency and technological adoption.
