摘要：Pakistan is the world’s fourth largest producer and third largest consumer of cotton. Using
data from 16 villages in two cotton-growing districts of Pakistan, we attempt to determine the
impacts of Bt cotton adoption on producers’ wellbeing employing the propensity score
matching method. While the results reveal positive impacts of Bt cotton on the wellbeing of
farmers in Pakistan, the extent of impact varies by agro-climatic conditions and by farm size.
The impact of Bt cotton adoption on yield for small farmers is about is about 50 percent of the
same for large farmers. Similarly, the impact of Bt cotton adoption on household income was
positive and significant for medium and large farmers but not for small farmers. The impacts
of Bt cotton on yield and income are larger under hot and humid conditions than under hot
and dry climatic conditions. Additional public-sector investments in monitoring and
assessments of pest infestations across climatic zones would be helpful to make the Bt cotton
technology widely beneficial in Pakistan.
