Seeing is Believing? Evidence from an Extension Network Experiment

The Impact of Strengthening Agricultural Extension Services: Evidence from Ethiopia

“…One of the main limitations of that study is the lack of detailed baseline data on the outcomes of interest, relying on recall data instead, and non-random placement of FFS. Kondylis et al (2017) evaluate the impact of two different modalities of the T&V extension delivery system, using a randomized control trial methodology in Mozambique. They compare the traditional decentralized system in which extension agents train contact farmers (who are then supposed to train other farmers in their communities) to an alternative in which contact farmers receive an additional centralized 3-day training.…”

Show and Tell: Causal Impacts of Field Days on Farmer Learning for Organic Inputs in Kenya

“…Some recent literature has specifically examined the spread of technology from trained farmers to others in their network. Looking at five-year panel data from Tanzania, Nakano et al (2018) found evidence of the diffusion of improved rice technology from trained primary farmers to other farmers in their villages, while Kondylis, Mueller, and Zhu (2017) show large positive effects from training contact farmers on community adoption rates of technology in Mozambique. In their survey of the FFS literature, however, Waddington et al (2014) found limited evidence of diffusion of information from FFS farmers to other farmers in their village.…”

The role of interactive radio programming in advancing women’s empowerment and crop and dietary diversity: Mixed methods evidence from Malawi

“…Whereas plenty of delivery tools and approaches are available, rigorous empirical evidence on whether and how those approaches work and under what conditions remains limited. Panel data analysis and randomized control trials are emerging to address this need (for example, BenYishay and Mobarak 2019; Kondylis, Mueller, and Zhu 2017;Larochelle et al 2017; Fu and Akter 2016;Aker, Ghosh, and Burrell 2016;Aker and Ksoll 2016;Krishnan and Patnam 2014).…”
