WebMay 9, 2024 · Vector Error Correction Mechanism (VECM) is estimated in the presence of cointegration among the system of variables. It allows us to estimate short-run as well as long-run coefficients. Using VECM estimation, we can analyze long-run equilibrium relationships among variables and short-run deviations from that equilibrium.
