Dynamics of Indian macroeconomic variables: a hac standard errors VECM approach

This study investigates the dynamic causal relationship between India’s GDP and key macroeconomic variables (exports, imports, inflation, exchange rate, BSE and NSE) over a period from January 2000 to December 2024 by using monthly data. Cointegration test has confirmed the presence of one cointegrating equation that means long-run equilibrium relationship exists along with short-run dynamics as provided by VECM estimates through HAC standard errors provided by Newey-West. The CUSUM test has confirmed overall model stability and while heteroskedasticity has been taken care of by applying HAC standard errors. The study has also shown both uni-directional as well as bi-directional casualties.
