This study empirically examines and compares the impact of foreign aid on growth in 6 South Asian countries: Bangladesh, Bhutan, India, Nepal, Pakistan, and Sri Lanka, using annual data over the period 1980–2019. The empirical results for comparative analysis are based on the methods of variance decomposition and impulse response function. The results show that the impact of foreign aid shock on the growth variation is about 1%–2% in 5 countries and 7.76% in Nepal. This means that the endogenous relationship between foreign aid and growth is not large in 6 South Asian countries. In addition, a foreign aid shock has a positive impact on growth in Bhutan and India, and has a negative impact on growth in other countries. A possible reason for the positive impact in Bhutan and India is that these countries have better governance and transparency than other South Asian countries. Further, the shock of foreign aid on the fluctuation of growth disappears in 2–3 years at the most, suggesting that most foreign aid is ineffectively managed and used for consumer goods. Therefore, it is necessary to improve governance and transparency so that foreign aid can be positively linked to growth, and it is desirable to provide foreign aid in the form of increasing capital goods.
