22 pages, This paper presents direct evidence on the impact of a specific extension program that is aimed at promoting the adoption of varieties resistant to the soybean cyst nematode (SCN), specifically the Iowa State University SCN-Resistant Soybean Variety Trials. We use two data sources: experimental data from these variety trials and a rich proprietary dataset on farmers’ seed purchases. Combining these data, we estimate the value of soybean cyst nematode-resistant variety availability, and the associated variety trials that provide information on their performance to farmers and seed companies. Given the scope and diffusion of this extension program, the focus of the analysis is on Iowa and northern Illinois over the period 2011–2016. Farmers’ seed choices are modeled in a discrete choice framework, specifically a one-level nested logit model. Using the estimated demand model, we find farmers’ marginal willingness to pay for soybean cyst nematode-resistant varieties, and for related extension information provided by the Iowa State University SCN-Resistant Soybean Variety Trials program, to be large. These results are confirmed by counterfactual analyses showing that, over the six-year period and region of the study, the total ex post welfare change associated with the existence of, and information about, SCN-resistant seeds is about $478 million. About one-third of this surplus is captured by seed suppliers, and two-thirds accrues to farmers.
19 pages, The COVID-19 pandemic has drastically affected people's lives around the world, including agricultural extension workers. To date, few studies have been conducted to understand the adaptation of extension services in Latin American countries during the pandemic. This mixed-methods study explored Latin-American extension professionals’ preparation to implement knowledge-sharing activities and sought to understand extension professionals' responsiveness to COVID-19. The results revealed significant differences in extension responsiveness, between field extension workers and in-office extension workers. Delving into this difference revealed that field extension professionals perceived lower responsiveness because they were not able to continue their pre-pandemic, face-to-face activities in the field with farmers; on the other hand, office extension workers were able to complete and respond to their annual program objectives by increasing institutional partnerships by virtual means. Resilience was found in the two phases of this study. Extension professionals were viewed by farmers as a reliable resource for addressing COVID-19 challenges. Extension professionals began using new communications technologies to train farmers, even though they were not trained in these technologies themselves. It will be important to begin formally incorporating the use of new technology, and alternative communication strategies with communities during crises, as part of preparation for field technicians.
