| New crop varieties often have been promoted in developing countries based upon superior yield vis-a-vis locally available varieties. This research presents a hedonic model for upland rice by drawing upon the input characteristics and consumer good characteristics model literature. Model specification tests determine that a combination of production and consumption characteristics best explains the willingness to pay for new upland rice varieties. This non-separable household model specification determined that four traits explain the willingness to pay for new rice varieties: plant cycle length, plant height, grain elongation/swelling and tenderness. Yield was not significant explanatory variable for the willingness to pay for seed. The implications... |

| Malaria and other transient illnesses have been recognized as factors constraining economic development in tropical countries. The purpose of this paper is to determine the direct and the indirect impact of transient illness shocks, caused primarily by malaria but also including other tropical illness, on family labor use in irrigated rice production in Mali. Family labor is the most important factor of production used in rice production in Mali and transient illness shocks may negatively impact labor supply, production and hence household welfare derived from agricultural income and consumption. Two labor demand models are estimated to determine whether illness does indeed reduce labor supply: one where the dependent variable only includes family labor... |

| Controlling for spatial effects in micro-economic studies of consumer and producer behavior necessitates a range of analytical modifications ranging from modest changes in data collection and the definition of variables to dramatic changes in the modeling of consumer and producer decision-making. This paper discusses conceptual, empirical, and data issues involved in modeling the spatial aspects of economic behavior in data rich environments. Attention is given to established and emerging agricultural economic applications of spatial data and spatial econometric methods at the micro-scale. Recent applications of individual and household data are featured, including models of land-use change at the urban-rural interface, agricultural land values, and... |

| Recent federal agricultural programs have accelerated the devolution of enterprise risk management responsibility from the state to individual producers. Using a biophysical simulation model, the risk management benefits of federal crop insurance and supplemental irrigation are derived and compared to uninsured rainfed crop production in an expected utility framework. Federal crop insurance programs are inefficient at reducing producer exposure to weather-related production risk in humid regions, and the risk management benefits from supplemental irrigation are found to be scale and technology dependent. Environmental policies that regulate resource development will increase the investment cost of irrigation alternatives and reduce economic feasibility. |

| The purpose of this research is to determine how technically efficient small-scale producers are in two provinces (North and South Kivu) in the Democratic of Republic (DR) of Congo at producing two different varieties of beans: bush and climbing beans. In addition to calculating the efficiency scores, this research attempts to identify what producer and field characteristics affect these scores. We hypothesize that bean producers will be more productive than producers in South Kivu and that climbing bean producers will be more productive than bush bean producers. Technical efficiency is estimated using a nonparametric approach. A tobit model is used to examine the effect of producer and field characteristic on the efficiency score. On average, farms... |

| Recently, discussion had reemerged over the value of integrated pest and crop management training, through intensive approaches such as farmer field schools or participatory training, as a development approach (Feder et al, 2004). This paper develops a model of human capital accumulation through participatory research and tests several hypotheses on the effectiveness of this approach to increase the adoption of soil conservation and fertility management innovations and improve farm productivity in southeast Asia. Bivariate Probit models with treatment effects are estimated using full information maximum likelihood (Evans and Schwab, 1995: Trost and Lee, 1984) and covariates related to changes in land allocation and productivity, measured before project... |

| This paper contrasts nonparametric data envelopment analysis (DEA) and free disposal hull (FDH) representations of dairy technology to determine whether factor indivisibilities and firm-specific location components affect economic performance. Location and capital structure variables, in addition to technology and firm structure, are used in a second-stage model to explain firm inefficiency using a Tobit estimator. Capital structure and location factors are correlated with firm efficiency in the DEA models but not the FDH indicating that the FDH representation may account for these factors in the in the first-stage efficiency modeling. Results indicate that failing to control for firm-specific spatial constraints and capital divisibilities will bias... |

| Recent projections on the impact of climate change argue that eastern and southern Africa will be two regions around the globe that will experience dramatic reductions in maize yields by mid‐century. Absent from these projections is any consideration for farmer adaptation of cropping practices or land reallocation. This research quantifies risk, loss and ambiguity aversion for a sample of smallholder Kenyan farmers using framed field experiments. This behavioral information, directly elicited, is used to condition the selection of maize varieties differentiated by drought tolerance, pest resistance, maturity, and seed price. Overall, the willingness to pay for drought tolerance and other attributes is highly heterogeneous as determined through a Latent... |
