Experimental Details

Interventions

Intervention(s)
We randomized different subsidies for cookstoves across a sample of 84 communities. These communities were randomly allocated in October 2014 to a control group, a zero-price group, a full price and a half price group (21 communities each).

In the three treatment groups, stove production units and installers were trained in a business-as-usual way. Furthermore, in cooperation with the installers we arranged a marketing event in each of the treatment communities, informing households about the stove’s main advantages and usage instructions. These events took place between May and August 2015. Rural dwellers in the visited communities could make orders for the ICS right after this marketing event, but also on a rolling basis. The three groups only differ in the price at which the stove was offered. The ordered ICS was installed in the weeks following the event. Households in the full and half-prize group could make payments in installments.
