Prior work
This trial does not extend or rely on any prior RCTs.
The proposed randomized control trial is designed to study the effect of nutrition and gender sensitive messaging embedded in the work of extension workers across four regions of Ethiopia. All kebeles in our sample are provided video-based agricultural content presented by agricultural extension workers. In randomly selected kebeles, these videos will be presented in a framing that encourages collaboration in the household and promotes women to be active participants in household decision-making. A subset of the kebeles in the collaboration arm will be randomly selected to also be provided with video-based agricultural extension that explicitly focuses on connecting agricultural decisions to improving nutrition outcomes in the household. The evaluation contributes to the literature by identifying whether agricultural extension is an effective method to improve nutrition awareness and outcomes, and whether government extension can be framed in a manner to promote female empowerment in households’ agricultural decision-making.

Experimental Details


The intervention we evaluate is complementing video-based agricultural extension with 1) messaging and framing that encourages and promotes women to be active decision-makers on agricultural decisions within the household, and 2) messaging that explicitly focuses on the connection between agricultural decisions and nutritional goals and outcomes for the household.

Experimental Design

Experimental Design
Our study is based on a cluster randomized controlled trial (RCT). A total of 200 kebeles (clustered villages) in 16 selected AGP2 woredas will be randomized into three experimental groups, stratifying by district (woreda).

The random assignment of the kebeles into the three experimental groups will be conducted as follows. One third of the kebeles (Control) will be assigned to receive the standard agricultural information, i.e. the videos that are shown in this treatment group do not specifically frame the information in a way that promotes increased participation of women in household decision-making process or encourage collaboration in the household. One third will be assigned to receive collaborative agricultural information (Treatment A), in which the videos promote women as being active participants in the household on agricultural decisions. And a final third will be assigned to receive a combination of the standard the standard agricultural information and nutrition information framed in the collaborative framework (Treatment B) .
