In this chapter we examine social networks among farmers in a developing country. We use detailed data on economic activities and social interactions between people living in four study villages in Ghana. It is clear that economic development in this region is being shaped by the networks of information, capital and influence that permeate these communities. This chapter explores the determinants of these important economic networks. We first describe the patterns of information, capital, labor and land transaction connections that are apparent in these villages. We then discuss the interconnections between the various economic networks. We relate the functional economic networks to more fundamental social relationships between people in a reduced form... |

We estimate the effects of higher quality healthcare usage on health, labor supply and schooling outcomes for sick individuals in Tanzania. Using exogenous variation in the cost of formal sector healthcare to predict treatment choice, we show that using better quality care improves health outcomes and changes the allocation of time amongst productive activities. In particular, sick adults who receive better quality care reallocate time from non-farm to farm labor, leaving total labor hours unchanged. Among sick children, school attendance significantly increases as a result of receiving higher quality healthcare, but labor allocations are unaffected. We interpret these results as evidence that healthcare has heterogeneous effects on marginal productivity... |

We develop a method to structurally estimate principal-agent models by ordinary least squares (OLS). We set up a general principal-agent model which explicitly incorporates the wealth levels of each party and the opportunity cost to the agent of entering the contract. This yields an optimal contract that is linearized by way of an Nth order Taylor approximation. This in turn imposes N(3N-1)/2 restrictions on the parameters and yields an empirical test of the canonical principal-agent model. In the application, we consider the case where N = 2 and apply our method to a sample of land tenancy contracts in rural Madagascar. Empirical tests lead to consistent failure to reject the hypotheses derived from our structural model, which lends support to our... |

Rapid economic growth in China has resulted in substantially improved household incomes. Diets have also changed, with a movement away from traditional foods and towards animal products and processed foods. Yet micronutrient deficiencies, particularly for calcium and vitamin A, are still widespread in China. In this research we model the determinants of the intakes of these two micronutrients using household panel data, asking particularly whether continuing income increases are likely to cause the deficiencies to be overcome. Nonparametric kernel regressions and random effects panel regression models are employed. The results show a statistically significant but relatively small positive income effect on both nutrient intakes. The local availability of... |

Market-based development efforts frequently create opportunities to generate income from goods previously produced and consumed within the household. Production within the household is often characterized by a gender and age division of labor. Market development efforts to improve well being may lead to unanticipated outcomes if household production decisions are non-cooperative. We develop and test models of household decision-making to investigate intra-household decision making in a nomadic pastoral setting from Kenya. Our results suggest that household decisions are contested, with husbands using migration decisions to resist wives ability to market milk. |

The construction of large dams is one of the most costly and controversial forms of public infrastructure investment in developing countries, but little is known about their impact. This paper studies the productivity and distributional effects of large dams in India. To account for endogenous placement of dams we use GIS data and the fact that river gradient affects a district's suitability for dams to provide instrumental variable estimates of their impact. We find that, in a district where a dam is built, agricultural production does not increase but poverty does. In contrast, districts located downstream from the dam benefit from increased irrigation and see agricultural production increase and poverty fall. Overall, our estimates suggest that large... |

This paper uses data from two waves of the Indonesia Family Life Survey (IFLS2-1997 and IFLS3-2000) to investigate whether households that belong to the same extended families pool their income to smooth their consumption. We exploit the fact that the survey also tracks and interviews split-off households during the follow-up surveys, enabling us to construct a panel of extended families. The findings suggest that in contradiction to the null hypothesis of extended-family income pooling, household own income still matters to household consumption even after controlling for extended family resources. The result stands after correcting for potential measurement error and endogeneity of income. More importantly, the findings also suggest that although the... |

Lending to the poor is expensive due to high screening, monitoring, and enforcement costs. Group lending advocates believe lenders overcome this by harnessing social connections. Using data from FINCA-Peru, I exploit a quasi-random group formation process to find evidence of peers successfully monitoring and enforcing joint-liability loans. Individuals with stronger social connections to their fellow group members (i.e., either living closer or being of a similar culture) have higher repayment and higher savings. Furthermore, I observe direct evidence that relationships deteriorate after default, and that through successful monitoring, individuals know who to punish and who not to punish after default. |

Various household survey indicators of adult nutrition and health status are analyzed as determinants of individual wages. However, survey indicators of health status may be heterogeneous, or a combination of health human capital formed by investment behavior and variation due to genotype, random shocks, and measurement error, which are uncontrolled by behavior. Although there are no definitive methods for distinguishing between human capital and genetic variation in health outcomes, alternative mappings of health status, such as height, on community health services, parent socioeconomic characteristics, and ethnic categories may be suggestive. Instrumental variable estimates of health human capital and residual sources of variation in measured health... |
