The marginal effect of ownership status on the probability of adoption is approximately 0.06 to 0.10. The effect relative to households who do not pay for their water at all is similar in magnitude to the effect of being an owner rather than a tenant. If the respondent stated that they took the appropriate environmental label into account in their purchasing decisions, this also increased the probability of adopting indoor water-efficient equipment, particularly for water-efficient washing machines and water flow restrictor taps. There are, of course, likely to be significant interactions between these three factors.
