Extended Data Fig. 9: Regression discontinuity around national and neighbourhood average.
The figures show the monthly water consumption by the distance to neighbourhood mean for households who consume below (sub-figure (a)) and above (sub-figure (b)) the national mean; and by the distance to national mean for households who consume below (sub-figure (c)) and above (sub-figure (d)) the neighbourhood mean. Monthly water consumption variable is residual of account fixed effects, year-month fixed effects, and weather and pollution controls. The average residual water consumptions below the cut-offs (distance<0) are shown in black dots and above the cut-offs (distance>0) are shown in blue dots. The fitted lines from robust locally weighted regressions below the cut-offs (distance<0) are shown in green and above the cut-offs (distance>0) are shown in yellow.
