| The agricultural trade of the Sudan is expected to develop under the recent dramatic increase of world food prices. Sudan as one of the developing countries and as price taker on the world agricultural market has been affected greatly by the world price increase. This paper aims at studying the impact of the increasing world food prices on developments of the agricultural crops trade sector of Sudan. In this paper a multimarket model is used as the main tool to estimate the increase of the world food prices on the crop trade sector. Multi-market analysis is a tool for simulating the effects of agricultural price policies on outcomes considered of interest to policy makers. The model under consideration takes the normal specification of a standard partial... |

| Conservation subsidies may be awarded for otherwise profitable projects, in which case they do not improve environmental quality. We show that transaction costs involved in such subsidy programs may induce farmers to reduce the size and scope of conservation projects. An empirical study shows that cost sharing in Maryland has resulted in simpler projects that provide no greater environmental protection. Water quality does not appear to be a goal of cost sharing; farm productivity and political considerations do. |

| This paper analyzes the effects of providing environmental amenities associated with open space in a discrete space urban model. The discrete space model assumes distinct neighborhoods in which developable land is homogeneous within a neighborhood but heterogeneous across neighborhoods. We solve for equilibrium allocation of development, prices and welfare given a pattern of open space provision. We also analyze the optimal provision of open space across neighborhoods. In equilibrium, housing density and price in a neighborhood is increasing in the amount of open space provided in that neighborhood. Whether housing density and prices in other neighborhoods increases or decreases depends on whether the push from reduced availability of developable land in... |

| In Nigeria 90% of the agricultural primary produce is in the hands of small holders cultivating between 0.8-4 hectares. Farm size expansion is limited by population pressure, land fragmentation, poor market opportunities and lack of finance. This article presents estimates of soil erosion control(SEC) and soil erosion damage costs (SEDC) in small farmers' fields in Nigeria and examines the contents and direction of the country’s agriculture and environment policies vis-à-vis the SEC among small farmers. It was found that 24% of the farmers’ spending on tillage/cultural practices was directed at the institution of SEC measures, and that SEC-related defensive expenditures was 3.7 times more than the estimated SEDCs. The capacity of small farmers to respond... |

| Genetic modification of crops has revolutionized food production, but it remains controversial due to food safety and environmental concerns. A recent food safety scare provides a natural experiment on the corn market's willingness to accept unapproved genetically modified organisms. In 2000, a genetically modified corn variety called StarLink was discovered in the food-corn supply, even though it was not approved for human consumption. To estimate the price impact of this event, we develop the relative price of a substitute method, which applies not only to the StarLink event but also to rare events in other markets. We apply this method to measure the price impact of the StarLink contamination on the U.S. corn market. We find that the contamination led... |

| The strategic choices of Small and Medium Enterprises in the agribusiness sector are fraught with large cost and revenue uncertainties. The transition to a new production system implies that SMEs must re-allocate resources and develop new strategies to achieve market goals. We highlight the agricultural, marketing and management literature on decision-making under risk for strategic decisions. Subsequently we discuss the various elicitation techniques to measure decision-makers' utility functions. That review indicates that one is able to measure the global utility function in a reliable and valid way. Particularly the measures based on experiments and rooted in expected utility framework seem to perform well. Furthermore, we develop various research... |
