Abstract
This research aims to estimate the price elasticity of demand for electric cooking in rural areas. We also aim to identify the degree of substitution away from traditional solid fuels when electric cooking is accessible. How do the cooking behavior and patterns change when households use electric stoves? What is the impact of electric stoves on household air pollution, and what are time-saving effects for women? self-reported health measures, and well-being?

Primary Outcomes

Primary Outcomes (end points)
Take-up of induction stove, Usage of induction stove, Household air pollution (PM2.5), Change in cooking fuel mix, LPG usage, Firewood use, Time use
Primary Outcomes (explanation)
PM2.5 will be measured at a 1-minute frequency using HAPEx optical particle sensors. These sensors will be rotated for a week every month across households.
Usage will be measured using electricity meters at a 1-minute frequency, which will be placed one week every month in those households that purchase electric stoves,

Secondary Outcomes

Secondary Outcomes (end points)
Self-reported health outcomes

Experimental Design

Experimental Design
To estimate the price elasticity, we will provide the electric stoves at different subsidized rates--low, moderate, and high levels (10%, 50%, and 90%) to the selected households. In addition to that, we will also provide electricity rebates to some selected households who receive low and high subsidies.
