This paper develops a two‐period Overlapping Generations (OLG) model of endogenous growth in which a two‐way relationship between social capital and human capital is studied. In order to illustrate the impact of public policies, the model is calibrated using the data for a low‐income country, India and a sensitivity analysis is reported under different parameter values. Based on the numerical analysis, this paper focuses on possible trade‐offs in the allocation of government spending between two productive components, that is, social capital‐related activities and education. The results of this paper show that an increase in the share of public spending on social capital‐related activities through a cut in spending on education or vice versa entails trade‐offs. However, the trade‐off fades away and the net impact on long‐run growth turns out to be positive for different parameter values in the case where a higher share of spending on education is financed by a cut in spending on social capital‐related activities but a policy in improving social capital accumulation at the expense of education is always detrimental to long‐run growth.
