| Pastoralists in East Africa's arid and semi-arid lands (ASAL) regularly confront climatic shocks triggering massive herd die-offs and loss of scarce wealth. On the surface, it appears puzzling that pastoralists do not make extensive use of livestock markets to offload animals when climatic shocks temporarily reduce the carrying capacity of local rangelands, and then use markets to restock their herds when local conditions recover. In recent years, donors and policy makers have begun to hypothesize that investments in livestock marketing systems might quickly pay for themselves through reduced demand for relief aid,by increasing pastoralist marketing responsiveness to temporal variation in range conditions. |

| We model interhousehold transfers between nomadic livestock herders as the state-dependent consequence of individuals' strategic interdependence resulting from the existence of multiple, opposing externalities. A public good security externality among individuals sharing a social (e.g., ethnic) identity in a potentially hostile environment creates incentives to band together. Self-interested interhousehold wealth transfers from wealthier herders to poorer ones may emerge endogenously within a limited wealth space as a means to motivate accompanying migration by the recipient. The distributional reach and size of the transfer are limited, however, by a resource appropriation externality related to the use of common property grazing lands. When this effect... |

| Public transfers of food aid are intended largely to support vulnerable populations in times of stress. We use high frequency panel data among Ethiopian and Kenyan pastoralists to test the efficacy of food aid targeting under three different targeting modalities, food aid's responsiveness to different types of shocks, and its relationship to private transfers. We find that self-targeting food-for-work or indicator-targeted free food distribution more effectively reach the poor than does food aid distributed according to community-based targeting. Food aid flows do not respond significantly to either covariate, community-level income or asset shocks, nor to idiosyncratic, household-level income or asset shocks. Rather, food aid flows appear to respond... |

| This paper introduces a simple method of price risk decomposition that determines the extent to which producer price risk is attributable to volatile inter-market margins, intra-day variation, intra-week (day of week) variation, or seasonality. We apply the method to livestock markets in northern Kenya, a setting of dramatic price volatility where price stabilization is a live policy issue. Large, variable inter-market basis is the single most important factor in explaining producer price risk in animals typically traded between markets. Local market conditions explain most price risk in other markets, in which traded animals rarely exit the region. Seasonality accounts for relatively little price risk faced by pastoralists in the dry lands of northern... |

| Although rice accounts for approximately forty-four percent of land under cultivation and forty-six percent of caloric intake in Madagascar, most farmers cannot produce enough rice to feed their families. Total rice production increased little in the country during the 1990s, and yields were stagnant and well below world average yields. Because of the importance of rice for both family income and nutrition and because of the significant role upland rice cultivation plays in deforestation in Madagascar, intensification of lowland rice production has been a major focus of many development interventions. The System of Rice Intensification (SRI) is a method that has been promoted and closely followed in Madagascar for more than ten years. SRI is remarkable... |

| This study explores the constraints on agricultural productivity and priorities in boosting productivity in rice, the main staple in Madagascar, using a range of different data sets and analytical methods, integrating qualitative assessments by farmers and quantitative evidence from panel data production function analysis and willingness-to-pay estimates for chemical fertilizer. Nationwide, farmers seek primarily labor productivity enhancing interventions, e.g., improved access to agricultural equipment, cattle and irrigation. Shock mitigation measures, land productivity increasing technologies and improved land tenure are reported to be much less important. Poorer farmers have significantly lower rice yields than richer farmers, as well as significantly... |

| Reverse tenancy, wherein poorer landlords rent out land to richer tenants on shares, is a common phenomenon. Yet, it does not fit existing theoretical models of sharecropping and has never before been modeled in the development microeconomics literature. We explain reverse tenancy contracts using an asset risk model that incorporates moral hazard. When choosing the terms of an agrarian contract, the landlord considers the impact of her choice on the probability that she will retain future rights to the rented land. Thus, this model captures the effect of tenure insecurity and property rights on agrarian contracts. The main testable implication of the theoretical model is that, as property rights become more secure, reverse tenancy tends to disappear. |

| In this world of plenty, almost half of the world's six billion people live on two dollars a day or less and the number living on less than one dollar a day has increased over the past fifteen years (World Bank 2000). Between one third and one half suffer under nutrition due to insufficient intake of calories, protein or critical micronutrients such as vitamin A, iodine and iron. More than one child in five lives in acute poverty. Why does such unnecessary injustice continue to disfigure a rich, technologically advanced world and what can be done to care for the poor and thereby to care for and honor God, as the Gospels instruct us? In attempting to answer those questions, at least partly, this paper offers some insights from recent research in economics,... |
