Última Ex Ante Economic Impact of Genetically Modified (GM) Cowpea in Benin AgEcon Dofonsou, Sika Gbegbelegbe; Lowenberg-DeBoer, James; Adeoti, Razack; Coulibaly, Ousmane; Lusk, Jayson L.. The net impact of pest-resistant GM crops on the welfare of both producers and consumers in developing countries is currently unknown and subject to speculation. This study uses choice-based conjoint protocol to estimate the net impact of pest-resistant Genetically Modified (GM) cowpea on net social welfare in Benin given price and income risks. Results imply that Bt cowpea will increase expected net social welfare by about $US 50 million per year in Benin given no inefficiencies in the seed sector. If inefficiencies in the seed sector are such that cowpea growers can access Bt cowpea seeds only 50% of the time, net benefits from Bt cowpea drop to about $US 11 million per year.

Ano: 2007 URL: http://purl.umn.edu/9817 EX ANTE NON-MARKET VALUATION FOR NOVEL PRODUCT: LITERATURE REVIEW AgEcon Dofonsou, Sika Gbegbelegbe; Lowenberg-DeBoer, James. This paper provides a critical review of the literature on non-market valuation methods to estimate the welfare impact of novel products; it is the first study to assess both observed data- and perception-based methods as non-market valuation methods. Observed databased methods include budgets, regression, mathematical programming, and simulation. Perceptions-based methods include the contingent valuation method, choice-based conjoint analysis and experimental methods. Findings imply that the preferred observed data-based method to estimate the ex ante economic impact of a new technology on the welfare of the farm household is a combination of simulation and mathematical programming. The preferred perception-based method for estimating the ex ante impact...
