Experimental Design
Exclusive contract access will be randomized at the market level, stratified by province and market size, determined by below or above median firm counts within the province from a census of firms. We will census all shops and sample 5, prioritizing those who in screening are interested in principle in stocking cookstoves or good industry fits and randomly selecting among those interested. We sample markets 3 kilometers or more apart to limit spillovers.
Firms are permitted to stock beginning after the baseline survey, and we will deliver approximately once per week during the study as we get orders.
We conduct follow up surveys beginning 2 months after baseline, with high frequency pricing surveys between as the budget permits.
Pricing experiments are implemented 3-6 months after baseline.
We may also conduct spillover surveys with unsampled firms 3-6 months after baseline if the budget permits. The aim of these is to measure information spillovers across firms and across markets.
Similarly, we may conduct experiments to study information diffusion during a follow up, namely by informing all shops in some markets about the goods existence to exogenously generate a scenario where knowledge has fully diffused. If we conduct these diffusion experiments, we are focused on how they affect competition/collusion, sales, and prices.
