| Stochastic dominance analysis was used to assess export performance in two Melanesian countries of similar size and structure that are comparatively well endowed with natural resources: Solomon Islands and Vanuatu. Total export values increased over the study period in Solomon Islands, brought about by a significant increase in the value of non-agricultural resource exports. Agricultural exports showed small increases but the average annual rate of growth was only 1.3 per cent for agricultural export values compared with 10.7 per cent in non-agricultural export values. The record of commodity export performance in Vanuatu over the study period was less impressive, with a small average annual decline in total export values. This decline was caused by... |

| Stochastic dominance analysis was used to assess export performance in Papua New Guinea from 1960 to 1999. A country with abundant natural resources, Papua New Guinea was able to experience significant growth in total export values throughout the final four decades of the 20th century, with each succeeding decade stochastically dominating the previous one. The expansion of mineral and energy exports from the early 1970s was the major source of this growth. The powerful influence of an expanding minerals and energy sector must nevertheless be of concern in that this sector and other non-agricultural resource sectors comprise mainly extractive or quasi-extractive industries given the production practices that currently exist. Little progress has been made... |

| This study evaluated the impacts of farm size and stochastic return variability on no-till (NT) rice profitability at the whole-farm level. Mixed integer programming was used to determine optimal machinery complements, fuel consumption, and machinery labor requirements for conventional till (CT) and NT rice-soybean farms of 1200, 2400, and 3600 acres in size. Crop yields, market prices, and prices for key production inputs were simulated to construct stochastic whole-farm net returns for each farm size under CT and NT management, and both first and second degree stochastic dominance analysis were used to rank cumulative distribution functions of whole-farm returns according to specified risk preferences. The results indicate NT farms exhibit second degree... |

| Much of the increase use of vertical coordination in the U.S. swine industry has taken place through contract production. While the incidence of contracting is much higher in nontraditional hog production areas, a growing number of Midwestern producers are being faced with contract options. A variety of contractual arrangements are available through feed companies, integrators, genetics firms, and packers. However, little is known about the profitability and risk characteristics of these alternatives. This research suggests that risk neutral producers in the Midwest would prefer independent production, and risk averse producers would prefer to choose among the various types of coordination arrangements. |

| Malt barley is an important specialty crop in the Northern Plains and growers mitigate risk with federally subsidized crop insurance and production contracts. However, growers face considerable risk due to "coverage gaps" in crop insurance that result in uncertain indemnity payments due to uncertainty of their crop meeting contract specifications. A stochastic dominance model is developed to evaluate alternative risk efficient strategies for growers with differing risk attitudes and production practices (irrigation vs. dryland). Results show that efficient choices are highly dependent on risk attitudes for dryland growers, but not irrigated growers. Sensitivities with respect to acceptance risk and level of crop insurance subsidization are presented.... |

| Land degradation, in the form of soil erosion and nutrient depletion, threatens food security and the sustainability of agricultural production in many developing countries. Governments and development agencies have invested substantial resources in promoting soil conservation practices, in an effort to improve environmental conditions and reduce poverty. However, very limited rigorous empirical work has examined the economics of adopting soil conservation technology. This paper investigates the impact of stone bunds1 on crop production value per hectare in low and high rainfall areas of the Ethiopian highlands using cross-sectional data from more than 900 households having multiple plots per household. We use modified random effects models, stochastic... |

| This report analyzes fruit and vegetable expenditures by low-income households and higher income households, and compares the sensitivity of both groups' purchases to changes in income. On average, low-income households spent $3.59 per capita per week on fruits and vegetables in 2000 while higher income households spent $5.02-a statistically significant difference. In addition, a statistical demand model indicates that marginal increases in income received by low-income households are not spent on additional fruits and vegetables. In contrast, increases in income received by higher income households do increase their fruit and vegetable expenditures. One interpretation of this finding is that low-income households will allocate an additional dollar of... |

| Stochastic simulation is used to analyze the effects of weather and output price risks on feeder cattle backgrounding systems common to the mid-south region of the United States. The results show that backgrounding systems beginning in the fall and ending from April to late August are associated with higher expected returns relative to summer backgrounding. However, winter backgrounding is associated with greater overall risk relative to summer backgrounding. Stochastic dominance analysis indicated that slightly risk averse backgrounders prefer both winter and summer baskgrounding but summer backgrounding is preferred by strongly risk averse decision makers. |

| Contract strategies can resolve some of the challenges that exist for property rights conformance of genetically modified (GM) crops. The purpose of this research is to determine how contract terms impact adoption decisions related to GM grain production and marketing. A simulation model was developed for prospective GM introduction in hard red spring (HRS) wheat, and distributions of net returns for growers were analyzed using stochastic dominance and stochastic efficiency. Results illustrate that contracts can be designed to induce desired behavior. Technology fees, probabilities of detection, and the level of non-GM premiums were the most notable factors influencing adoption decisions. In addition, point-of-delivery pricing and premiums for non-GM... |

| Stochastic dominance analysis was used to assess export performance in two Polynesian countries of similar size and structure that are both marginally endowed with natural resources: Samoa and Tonga. In general, total and agricultural export values declined over the study period in both countries, brought about by a significant decline in the value of agricultural exports while non- agricultural exports showed small increases. The one exception to this trend was in Tonga during the 1990s when squash exports brought about a revival in agricultural export values. Results suggest that these countries are likely to struggle to achieve sustainable economic development, given their limited natural resource endowments. The fisheries sector holds the key to... |

| This paper presents the first empirical test with German establishment level data of a hypothesis derived by Helpman, Melitz and Yeaple in a model that explains the decision of heterogeneous firms to serve foreign markets either trough exports or foreign direct investment: only the more productive firms choose to serve the foreign markets, and the most productive among this group will further choose to serve these markets via foreign direct investments. Using a non-parametric test for first order stochastic dominance it is shown that, in line with this hypothesis, the productivity distribution of foreign direct investors dominates that of exporters, which in turn dominates that of national market suppliers. |
