The All-Korea system-GMM model is the paper's main specification (its SR elasticity -0.103 and the derived LR elasticity -0.513 carry the results narrative); the Seoul and Non-Seoul models are explicitly introduced only "for the comparison" (p. 5). || "The short-run price elasticity is estimated to be -0.103 which is consistent with the findings in Durmaz et al. (2020) ... For the comparison, Table 4 also reports the estimation results for both the Seoul Capital Area and Non-Seoul Capital Area." (p. 5, printed)
