The Efficiency of Emerging Stock Markets: Empirical Evidence from the South Asian Region

This paper examines weak form efficiency in the stock markets of India, Sri Lanka, Pakistan and Bangladesh; and the linkages between these four markets. The Augmented Dicky Fuller (ADF-1979), the Phillip-Perron (PP-1988), the Dicky-Fuller Generalized Least Square (DF-GLS 1996) and Elliot-Rothenber-Stock (ERS – 1996) tests are used to examine stock market efficiency. Weak form efficiency is supported by the classical unit root tests, however, it is not strongly supported for Bangladesh under the DF-GLS and ERS tests. The cointegration and Granger causality tests indicate a high degree of interdependence between the South Asian stock markets.
