Bales and balance : a review of the methods used to assess the economic impact of Bt cotton on farmers in developing economies
Abstract
Forty-seven peer-reviewed articles are assessed that have applied economics methods to measure the farm-level impacts of Bt cotton in developing agriculture from 1996. Most often, the contextual factors that influence whether a new variety succeeds or fails are more critical than whether yield advantages can be demonstrated in on-farm trials. While the evidence is promising, the balance sheet remains inconclusive, in part because of some methodological limitations and in part because institutional and political context, which is mutable and often ignored, shapes economic impacts, especially over the longer term.
