The adoption of modern stoves is not the only barrier to this transition, since households with access to cleaner technologies often continue using traditional stoves alongside these. One reason for this \u2018stove stacking\u2019 is that modern cooking technologies are often considered incompatible with established and customary household cooking practices. These practices are not only 'normative\u2019 but often \u2018habitual\u2019, making them particularly difficult to change. This paper asks whether behavioral insights can help to better align household cooking practices with the capabilities of modern stoves, using a group session implemented as a randomized control trial in peri-urban Rwanda. Based on a behavioral model of the clean cooking transition, the intervention seeks to establish a new cooking habit among participants (pre-soaking beans before cooking them) by targeting their attitudes, norms and perceived behavioral control, as well as using contextual cues to encourage repetition of the behavior over time. Results point to the successful formation of a new energy-efficient cooking habit that lowered cook times on traditional stoves on days in which beans were cooked. Importantly, the intervention also had a positive effect on attitudes about the suitability of modern stoves for cooking beans, and increased participants\u2019 aspirations and expectations to purchase these devices.","geographic_units":[{"name":"Rwanda","code":"RWA"}],"keywords":[{"name":"Improved Cookstoves"},{"name":"Clean Transition"},{"name":"Behavioral Barriers"},{"name":"Cooking Practices"},{"name":"Habits"}],"topics":[{"id":"C93","uri":"https:\/\/www.aeaweb.org\/econlit\/jelCodes.php?view=jel","vocabulary":"Journal of Economic Literature (JEL)","name":"Field Experiments","parent_id":"C9"},{"id":" D91","uri":"https:\/\/www.aeaweb.org\/econlit\/jelCodes.php?view=jel","vocabulary":"Journal of Economic Literature (JEL)","name":"Role and Effects of Psychological, Emotional, Social, and Cognitive Factors on Decision Making","parent_id":"D9"},{"id":" O13","uri":"https:\/\/www.aeaweb.org\/econlit\/jelCodes.php?view=jel","vocabulary":"Journal of Economic Literature (JEL)","name":"Agriculture \u2022 Natural Resources \u2022 Energy \u2022 Environment \u2022 Other Primary Products","parent_id":"O1"},{"id":" O33","uri":"https:\/\/www.aeaweb.org\/econlit\/jelCodes.php?view=jel","vocabulary":"Journal of Economic Literature (JEL)","name":"Technological Change: Choices and Consequences \u2022 Diffusion Processes","parent_id":"O3"},{"id":" Q41","uri":"https:\/\/www.aeaweb.org\/econlit\/jelCodes.php?view=jel","vocabulary":"Journal of Economic Literature (JEL)","name":"Demand and Supply \u2022 Prices","parent_id":"Q4"},{"id":" Q53","uri":"https:\/\/www.aeaweb.org\/econlit\/jelCodes.php?view=jel","vocabulary":"Journal of Economic Literature (JEL)","name":"Air Pollution \u2022 Water Pollution \u2022 Noise \u2022 Hazardous Waste \u2022 Solid Waste \u2022 Recycling","parent_id":"Q5"}],"output":[{"type":"Working Paper","description":"Policy Research Working Papers (PRWP)","title":"From Habits To Hardware: A Field Experiment On Energy-Saving Cooking Practices In Rwanda"}],"language":[{"name":"English","code":"EN"}],"technology_requirements":"Run time: 16 minutes","disclaimer":"The materials in the reproducibility packages are distributed as they were prepared by the staff of the International Bank for Reconstruction and Development\/The World Bank.
