Table 3 DOLS long-run sectoral elasticities are the only elasticity estimates reported (one per sector, no alternatives); the author explicitly prefers the DOLS augmented cointegrating specification over the ARDL benchmark and uses these estimates for all forecasts/policy scenarios. || "Since DOLS is an efficient estimator and the forecast intervals tend to be tighter in the augmented cointegrating specification, implying higher precision of the forecast for decision-making, this modeling approach is preferred."
