Tables 2 and 4 report full hedonic columns; Tables 3, 5, 6, 8, 9 report only the energy-efficiency treatment (and income-category dummies in Table 5) with dwelling controls suppressed. 'Robust regression' columns (Table 2 c4-c5, Table 4 c4-c5, Table 5 c2,c5) are outlier-robust M-estimation, coded estimator 'other'. Table 8 uses propensity score as covariate (c1,c3) or PS-matched samples (c2,c4); Table 9 uses CEM-weighted samples. Building-year (construction period) dummies are printed without SEs (stars only; omitted category pre-1901); a dummy for double construction years is included but unreported. 'Rent' is the monthly fee to the tenant association (log SEK), not a market rent. Stars: *** p<0.01, ** p<0.05, * p<0.1."
