Understanding Adoption for Clean Cookstoves: A Demand Study

Not Applicable

Completed

• Conditions: Consumer Behavior

• Registration Number: NCT04454944
• Lead Sponsor: Columbia University

Brief 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.

Detailed Description

The study will assess if demand for LPG in rural settings in Ghana is price elastic - and by how much - by providing different levels of LPG price subsidies. It will also ascertain if demand is influenced by distance by allocating participants to varying distances to points of LPG supply. Finally, it will assess factors that could affect the demand for LPG such as availability and price of other fuels for cooking, and income levels.

In particular the objectives of the study are:

1. To determine if demand for LPG is price elastic

2. To determine if demand for LPG is influenced by distance

3. To ascertain what other factors aside the price of LPG, and distance to point of LPG supply, determine the demand for LPG

4. To document the successes and challenges of introducing a subsidy for LPG in rural settings
