Linear and Nonlinear Causal Relationships Between International Reserves and Economic Growth: Evidence from India

This study investigates linear and nonlinear causal relationships between accumulated international reserves (IR) and economic growth (Econ) in the case of India. The present study is carried out using quarterly data ranging from the period of the first quarter of 1985 to the fourth quarter of 2014. The study used econometric tools such as the augmented Dickey–Fuller (ADF) unit root test, the linear Granger causality test, Johansen’s cointegration test, the Brock, Dechert and Scheinkman (BDS) test and the nonlinear Granger causality test developed by Hiemstra and Jones. The study establishes that there exists a bidirectional linear causality. The Hiemstra and Jones test reveals a bidirectional nonlinear causal relationship between the variables. In light of these results, the study suggests that reserves accumulation can be implemented in India provided that excess of reserves are invested in alternative sources such as economic infrastructure projects and regional infrastructure development.
