Summary

The aim of the Adoption study is to determine how best to encourage people to adopt clean cookstoves in order to diminish the global health risk of household air pollution. The study harnesses an existing cohort in Ghana to study factors that increase the adoption of clean cookstoves, and to test strategies to promote adoption and continued use. Limited past research has shown that the demand for clean cookstoves is low, and that households continue to use traditional hearths even when they have clean cookstoves. This behavior threatens to undermine clean cookstove intervention programs, such as those promoted by the Global Alliance for Clean Cookstoves. The proposed study aims to ascertain the demand curve for liquified petroleum gas (LPG) in the Kintampo North Municipality and South district.

Conditions

  • Consumer Behavior

Interventions

BEHAVIORAL

LPG subsidy

Different subsidy rates, ranging between 0% and 100% (listed below) will be written on cards. Individuals will randomly select a card to display the subsidy rate for each household. The card will be concealed with a scratch-off sticker, with a higher likelihood of drawing a high price (low subsidy) than a low price (high subsidy) given that take up will be higher in the latter group.

BEHAVIORAL

Distance allocation

We will set up fuel supply depots to increase the convenience and lower costs and hassle associated with traveling to an established filling station. The supply depots will mirror a recirculation model of LPG distribution currently being piloted by the National Petroleum Authority of Ghana. Households will be randomly assigned to one of the supply depots in advance or to continue refilling their cylinder at the filling station.
