| Resumo: | In Mexico, dry beans are the second most important crop after maize, both in terms of production and consumption. Approximately 85% of the countrys bean crop is grown under rainfed conditions and of these, 62% is in Northern Mexico. Therefore, the assessment of the economic impact of bean research in Northern Mexico is important to provide decision-makers with information needed to improve the allocation of research resources. The objectives of this study were to analyze the adoption of the improved bean varieties released by the National Research Institute for Forestry, Agriculture, and Livestock (INIFAP) in the 90´s, and estimate the net social gains generated by public investment to develop improved bean varieties in Northern Mexico. The methods used in this study included the rapid appraisal of the bean subsector, the statistical and econometric analysis of farmers survey data, and the use of the economic surplus method to estimate the economic returns to public investment in bean research. The adoption analysis indicated that the improved bean varieties Pinto Villa and Pinto Mestizo have been adopted in 38% of the bean production area in the states of Chihuahua and Durango and that these varieties have yields 20.6% higher than traditional pinto bean varieties. The improved varieties were distributed through the governments seed distribution program Kilo por Kilo. The economic analysis indicates that public investment in bean research is profitable (IRR=21% vs. OCC=10%). These results imply that the government should continue investing in bean research in Northern Mexico to promote agricultural development and to improve the welfare of bean farmers under rainfed conditions and low-income consumers. |
