Authors' headline own-price elasticities are the seasonal FE and PMG estimates in Table 6; the abstract and conclusion stress that summer own-price elasticity is lower than non-summer, and that long-run elasticities are elastic. Marked the four directly-estimated Table 5 lnPIV coefficients (FE-SR and PMG-LR, summer and non-summer) as preferred since they carry printed uncertainty. || 'Both the adjustment speed and own price elasticity during the summer months are found to be lower than those in the non-summer months' (p.168, abstract)
