Theoretical models have been developed in recent years for analysing the problem of choice of technique for dualistic economies such as Bangladesh. But implications of these models have generally been explored on the basis of assumed values of parameters. This paper experiments with a variant of these models with actual values of the parameters estimated from Bangladeshi data. The model is simulated to derive implications for choice of technique at different stages of economic development. By using a social welfare function which takes note of inter-sectoral (but not intra-sectoral) equity, the model shows that at the present stage of development, greater emphasis should be laid on generating savings, even if at the cost of lower labour-intensity in the choice of investment projects. But more labour-intensive projects should be encouraged as the traditional sector gets increasingly absorbed in the modern sector.
