| Winter wheat may be grown in the Southern Plains either to produce grain only, or as a dual-purpose crop to produce both fall-winter forage and grain. The objective of the research is to determine expected net returns for both production systems. The estimated expected net value of the dualpurpose system stocked with steers with an initial weight of 450 pounds is from $38 to $92 per acre greater than that of the grain-only system. The economic success of dual-purpose wheat depends on a number of management factors including stocking density. |

| Low-input farming practices in many parts of the developing world have pushed cultivation onto marginal lands. Sustainability of already fragile ecosystems is threatened. Farmers place a high priority on satisfying subsistence food needs with on-farm production. Population pressure is high throughout much of Sub-Saharan Africa. Farmers in those regions are challenged by the need to put continually more food on their table over the coming years. An optimal control model was developed to investigate alternative farming practices within this setting. Namely, whether farmers would choose continued land expansion of if they would adopt crop intensive practices. The model included an environmental subcomponent to estimate the degradation costs from continued... |

| Cotton has been a success story in West Africa since independence swept the region in the early 1960's. Today, however, 'white gold' is struggling to maintain its allure. Recent declines in world cotton markets have created a crisis in the region's cotton sectors. Cotton is still being produced within an institutional structure that dates back to the independence era of the early 1960's. The new era of volatile cotton markets, new technological frontiers, and global challenges are placing demands on institutional change. This paper uses an economic model of the agricultural sector to predict the impacts of cotton liberalization. Shifting control from the state into the hands of the private sector would provide significant benefits to society. Farmers in... |

| The projected long-run increase in corn prices from $2.50 to $3.50 per bushel is expected to have a similar effect on feed prices, pushing up feed costs by as much as 50 percent. With feed costs on the rise, increasing forage production through more intensive management techniques becomes a potentially viable option. This study uses experimental data from a seven-year study in the Oklahoma Panhandle to assess the economic feasibility of intensifying forage production. Four commonly used forage grasses in the region were field tested using two alternative fertilizer sources – swine effluent and urea. The results found that only the two cool season grasses – orchard grass and wheatgrass – generated positive economic returns under intensification. |

| The 2005 food crisis centered in Niger received worldwide attention and extensive media coverage. Crops suffered from poor rainfall and were plagued by locusts throughout the growing season. Malnutrition flourished with the sudden disruption in food supplies. One-fifth of Niger's children suffered from moderate to severe forms of malnutrition by the summer of 2005. In an era of increased awareness and the introduction of famine early warning systems, the development community was left wondering why they were for the most part caught off guard by the food crisis. This paper tests whether market prices and price discovery could have played an active role in detecting the food crisis. Directed acyclic graphs are used to test whether price discovery... |
