This paper seeks to examine the relationship between inflation and GDP growth for four South Asian countries (Bangladesh, India, Pakistan and Sri Lanka). A comparison of empirical evidence is obtained from the cointegration and error correction models using annual data collected from the IMF International Financial Statistics.

These results have important policy implications. Moderate inflation is helpful to growth, but faster economic growth feeds back into inflation. Thus, these countries are on a knife-edge
