Dear Authors,
Could you clarify the rationale for using FMOLS, CCR, and DOLS over alternative methods and how data anomalies or reverse causality were addressed? Additionally, how were structural differences among the grouped countries considered, and how were conflicting findings on economic complexity’s impact on emissions reconciled (e.g., [24, 39, 54])? Lastly, could you provide more transparency on the derivation of the economic complexity index?
