Logistic regression results of revealed preference analysis. Dependent variable dichotomous (requested an empty = 1, no request = 0). Households were given coupons with randomly assigned volumetric prices. ‘Household responsible’ implies that households were fully or partially responsible for costs associated with pit maintenance (as opposed to the landlord having full responsibility).
