Papier: Household water savings from home visits: information, technology and price effects

Abstract: This paper studies the water consumption choices of households in response to policy interventions by a water utility. We specifically study the effects of home visits and billing changes, and estimate the water-saving effects from information, technology and prices. Home visits consist of information provision (information) and the installation of water-saving devices (technology). Billing changes migrate households from flat fees to variable fees (price). Using a staggered difference-in-differences approach we disentangle the three effects. We find a significant effect from home visits (technology and information) on water savings of about 15-20%. Interestingly, this effect is persistent. Billing changes (price) lead to a temporary reduction in water consumption of about 2%. This effect fades away over the course of a year. Throughout we find that households with higher baseline water usage respond with more water savings to both interventions, even in percentage terms
