This paper used a spatial and temporal price equilibrium model to assess the potential impacts of farmers in West and Central Africa adopting Bacillus thuringiensis (Bt) cowpea (Vigna unguiculata (L.) Walp). The results showed that regional cowpea prices would decrease, leading to increased regional demand and increased supply only in adopting countries. Total cowpea traded and regional welfare would increase, but producers in nonadopting countries would lose. The results thus emphasize regional adoption of any Bt cowpea and suggest that policy makers devise ways of ensuring equitable distribution of benefits.
