Abstract
Small-holder farmers in low-income countries face substantial weather risk. To reduce these risks, governments provide long-range forecasts about the amount of rain that will occur during the agricultural season, which can be disseminated in advance of the start of the season. In this project, we partner with the Indian Ministry of Agriculture and Farmers' Welfare (MoA&FW) to randomize SMS-based dissemination of the Indian Meterological Department's India-wide total monsoonal rainfall forecast among 128,000 farmers living in 22 subdistricts where this forecast has been shown to be particularly effective. We will measure the effects of these forecasts on farmer beliefs and agricultural activity.

Experimental Design

Experimental Design
In 22 Indian subdistricts, we will randomize 25% of farmers enrolled on the PM-Kisan platform to receive forecast SMS messages (treatment) and 75% of PM-Kisan farmers not to receive these messages (control), with approximately 97,000 farmers in the control group and 32,000 farmers in the treatment group across all subdistricts. The randomization is performed at the individual level, and is stratified by subdistrict.
