The paper reports exactly one FD-GMM partial-adjustment specification per group — national SR & LR (Table 9: -0.5052/-0.5199, discussed as "the long-run price elasticity at national level is -0.5199, while the short-run elasticity is -0.5052", p. 15) plus one per income region (Table 11) and one per temperature region (Table 14); the six regional estimates are the abstract's headline finding and the ARDL alternative was dropped by the authors for low significance, so all eight coded rows are the authors' estimates (note: 900017, cold region, is statistically insignificant but is still their unique cold-region estimate discussed in the text). || "The price elasticity is the greatest in the low income and mild temperature regions."
