| We quantify the importance of peer effects in group lending by estimating a static game of incomplete information. In our model, group members make their repayment decisions simultaneously based on their household and loan characteristics as well as their expectations on other members' repayment decisions. Exploiting a rich data set of a microfinance program in India, our estimation results suggest that the probability of a member making a full repayment would be 15 percentage points higher if all the other fellow members make full repayment compared to the case where none of the other members repay in full. We also find that large inconsistencies exist in the estimated effects of other variables in models that do not incorporate peer effects and control... |

| By altering the probability distribution of farm income, crop insurance programs affect farmer's input use decision. Ramaswami's (1993) one-shock model analyzed the effect of the crop insurance on single input use by allowing the randomness of yield while keeping price constant in revenue determination. The total effect of actuarially fair insurance on input use was decomposed into risk reduction effect and moral hazard effect, and the directions of the two effects were examined. He showed that the total impact of actuarially fair crop insurance on input use was a) to reduce it if the input was risk decreasing and b) indeterminate if the input was risk increasing. However, the evidence from previous empirical work has been mixed. Horowitz and Lichtenberg... |

| We use a combination of pipeline comparison, propensity score matching, and double differences to evaluate economic and social impacts of a large community driven development program in India. While we find positive empowerment and nutritional effects for households in program areas, allowing heterogeneity of program impact yields additional insights. First, social and economic empowerment increased equally for participants and non-participants in program areas, pointing towards positive externalities. Second, nutritional benefits were more pronounced for new participants than for members of pre-existing self-help groups who joined the program. Third, evidence of higher consumption -but not income or asset formation- by new and converted participants... |

| Site-specific nitrogen application (SSNA) has been considered a potentially more efficient nitrogen (N) management than uniform N application (UNA), because it tailors the N application rate to meet crop needs. However, previous studies on the profitability of SSNA were inconclusive. This study examines the conventional N fertilizer recommendation as a possible reason for the poor profitability of previous SSNA studies. Most previous SSNA experiments followed state-level N recommendations based on yield goals and/or soil nutrient levels that assume corn yield response to N does not vary site-specifically. This study challenges that assumption. It examines a set of six continuous site characteristic variables, more than any previous study, in order to... |

| We argue that existing agricultural insurance valuation models are limited either because they are not complete equilibrium models that price the non-diversifiable risk involved in issuing insurance contracts, or they assume complete markets which appears at odds with most applications of agricultural insurance. We also propose two new incomplete market models and derive an insurance valuation formula for each under the assumption of constant relative risk aversion preferences and lognormally distributed random variables. The two models differ in the way they treat trade in insurance contracts, with one model allowing insurers and insureds to trade freely on a liquid secondary market, while the other requires insurance firms to act as brokers between... |

| We demonstrate how a recently developed model selection procedure can be used to choose among competing stochastic frontier models where inefficiency depends on firm characteristics. We provide evidence on the power of this procedure. Moreover, we examine the effects of model choice on estimation results. We find that different models can lead to rather different magnitudes of the partial effects of the exogenous factors. However, because the model selection procedure gives an unambiguous choice of best model, and because bootstrapping indicates that the procedure is reliable, we conclude that it does not matter whether other models give different results. |

| Information on typical differences in prices and price risk (as measured by the variances of prices) across marketing arrangements aids fed cattle producers in making choices about methods to use for selling fed cattle to beef packers. This information is also useful for policy discussions on merits and drawbacks of alternative marketing arrangements. As part of the congressionally mandated Livestock and Meat Marketing Study, we investigated differences in prices and price risk for fed cattle cash market and alternative marketing arrangements. The modeling approach, which is similar to a hedonic model, controls for differences in cattle quality and delivery month and accounts for the within- and across-week correlation in prices. The analysis uses a recent... |
