| In the Northern Andes, one of the riskiest agriculture climates in the world, farmers use sharecropping to obtain seed, their most costly input. With survey data from Peru, this paper calculates that the cost of seed, when it is provided though sharecropping, is two times higher than the market price. We test the hypothesis that risk-averse farmers are willing to pay more to receive seed through sharecropping because the contract provides implicit crop insurance. |

| The practice of mutual insurance is conditioned by two types of transaction costs: "association" costs in establishing links with insurance partners and "extraction" costs in using these links to implement insurance transfers. Data on insurance-motivated water exchanges among households along two irrigation canals in Pakistan show that households exchange bilaterally with neighbors and family members but the majority exchange with members of tightly knit clusters. We, therefore, develop a model that endogenizes both cluster formation and the quality of insurance in the chosen cluster as a function of the relative importance of association and extraction costs. Full insurance at the community level, the object of most empirical tests of mutual insurance, is... |

| Using survey-data from Peru, this paper evaluates the impact of a pilot farmer-field-school (FFS) program on farmers' knowledge of integrated pest management (IPM) practices related to potato cultivation. We use both regression analysis controlling for participation and a propensity score matching approach to create a comparison group similar to the FFS participants in observable characteristics. Results are robust across the two approaches as well as with different matching methods. We find that farmers who participate in the program have significantly more knowledge about IPM practices than those in the non-participant comparison group. We also find that improved knowledge about IPM practices has a significant impact on productivity in potato production. |

| The impact of global climate change on the less developed countries is analyzed using archetype CGE-multimarket models for three economies representing the poor cereal importing nations of Africa, Asia, and Latin America. The objective is to predict the differential impact of climate change across continents on macroeconomic variables, sectoral responses, and household income and food consumption effects, particularly among the poorest. Results show that all these countries will lose and that their agricultural outputs will fall, but that Africa will be by far the most severely affected. Countervailing policies to mitigate negative effects should focus on the production of food crops in Africa and of export crops in Latin America and Asia. |
