Authors explicitly reject the ECM (positive gamma, no return to equilibrium) and adopt the VAR(1) representation as the final long-run estimator; obs 3237 (VAR DLPrix(-1) = -0.247393) is the authors' chosen price elasticity || 'we cannot use the error correction model and we should pass to the Vector Autoregressive Regression to estimate the electricity demand in Tunisia in the long-run' (p.717); 'an increase of 1% leads ... to a fall of 0.24% in the electricity consumption in the long-run' (p.717)
