Can Peers Improve Agricultural Revenue?, Tisorn Songsermsawas, Kathy Baylis, Ashwini Chhatre, Hope Michelson

Crop revenues vary greatly among farmers and the source of that variation is not fully understood. Using a household survey from India, we estimate peer effects on cash crop revenue. Results show that 60% of farmers' revenue can be explained by peers. Peer effects in input expenditure and land allocation cannot fully explain the variation in revenue, implying peers may also associate with management, negotiation and marketing strategies. Although caste-based networks are important, their effect is substantially smaller than that of self-reported peers. Peer effects are strongest for agricultural peers and in the cultivation of a new crop.

Honey bee colony losses are a major concern in the US and across the globe. Long-term data on losses are critical for putting yearly losses in context. US colony loss surveys have been conducted yearly since the winter of 2006-7. Here we report the results from the eighth annual survey on winter losses, and the second annual survey of summer and annual losses. There were 7,425 valid respondents (7,123 backyard, 190 sideline, and 112 commercial beekeepers) managing 497,855 colonies, 19% of the total US colonies. Total losses reported were 19.8% [95% CI: 19.3-20.3%] over the summer, 23.7% [95% CI: 23.3-24.1%] …
