The Role And Implications Of Negotiation In Fed Cattle Transactions, Taralee Hudson
The Role And Implications Of Negotiation In Fed Cattle Transactions, Taralee Hudson
Department of Agricultural Economics: Dissertations, Theses, and Student Research
Within the past three decades, a significant evolution has occurred in how fed cattle are bought and sold. Driven by changes in the quality of beef and consumer health preferences, the beef industry began to advocate for “value-based marketing,” resulting in the development of grid pricing and eventually formula transactions. Alternative marketing arrangements (AMAs) have become the predominant method used for the sale of fed cattle, ultimately resulting in fewer transactions in the negotiated cash market. Such market conditions have recently reignited concerns among industry stakeholders about potentially uncompetitive outcomes for beef producers, particularly after the occurrence of sequential Black …
Regenerative Farming Practices: How Much Carbon Do They Sequester?, Andrew M. Havens
Regenerative Farming Practices: How Much Carbon Do They Sequester?, Andrew M. Havens
Department of Agricultural Economics: Dissertations, Theses, and Student Research
Along with the recent rise of voluntary carbon markets comes potential carbon credit producers seeking reliable information on how much carbon they can expect to sequester. In this thesis a distribution of expected sequestration outcomes is constructed using cost-benefit analysis and data gathered from agronomic experiments and land-grant university crop budgets for cover crops and no-till practices. The inverse cumulative distribution of carbon sequestration outcomes from adopting a regenerative agricultural practice is visualized and the net social benefit of paying farmers to produce carbon credits is estimated. Results show that on average there is between $29.02 and $37.20 of social …
Irrigation Management, Environment, And Profits: Who Wins?, Emily O'Donnell
Irrigation Management, Environment, And Profits: Who Wins?, Emily O'Donnell
Department of Agricultural Economics: Dissertations, Theses, and Student Research
The impact of irrigation technology on farmers’ management strategies and resulting environmental benefits depends upon agronomic properties and market forces. We evaluate the role of deficit irrigation using soil moisture probe technology on corn yield and evapotranspiration, which is a measure of water use efficiency. Evapotranspiration represents the water that transits through the plant during planting to harvest (transpiration) and the evaporation from the soil into the environment, or the displaced water in the production process. We develop yield and evapotranspiration response functions to inform a constrained profit maximization model used to identify the optimal irrigation level across a variety …
Econometric Estimation Of Groundwater Depth Change For The High Plains Aquifer, Jonathan R. Sims
Econometric Estimation Of Groundwater Depth Change For The High Plains Aquifer, Jonathan R. Sims
Department of Agricultural Economics: Dissertations, Theses, and Student Research
This article presents a new method for estimating changes in depth to groundwater at a yearly, county level and incorporates these estimates as the dependent variable of econometric models for the High Plains aquifer. The High Plains (Ogallala) aquifer underlies eight states in the central United States and is the primary source of irrigation water for this large food producing region. The stock of groundwater is a finite, non-renewable resource with minimal recharge in most areas. Many fields of study, including hydrology and agricultural economics, are interested in depth to groundwater changes because they serve as a proxy for estimating …
U.S. Mushroom Import Demand Estimation With Source Differentiated Aids And Rotterdam Models, Jun Li
U.S. Mushroom Import Demand Estimation With Source Differentiated Aids And Rotterdam Models, Jun Li
Department of Agricultural Economics: Dissertations, Theses, and Student Research
While technically considered as fungi, mushrooms are often classified as vegetables because they provide many of the nutritional attributes of produce as well as meat, beans, and grains. The U.S. is the largest consumer of mushrooms and the share of imports in total consumption of mushrooms has been rising and will likely continue to rise as U.S. consumers increasingly adopt healthier diets. While most of U.S. fresh mushroom imports are from Canada, China, Mexico and South Korea, most of U.S. canned mushroom imports are from China, India, Indonesia, and the Netherlands.
The contribution of this thesis is to provide the …
The Environmental And Health Costs Of Alternative Diets: A Comparative Study Of The U.S. Diet Relative To The French, Japanese, Mediterranean, And Nordic Diets, Sarah Rehkamp
Department of Agricultural Economics: Dissertations, Theses, and Student Research
This thesis contributes to the literature on sustainable consumption by using scenario analysis to evaluate the environmental and health costs of the U.S. diet relative to the French, Japanese, Mediterranean, and Nordic diets, identified in the literature as healthier diets. As a first step in estimating environmental costs, the energy efficiencies of each diet are calculated by decomposing each of the diets into their respective components. Then, the dietary efficiencies are translated into CO2 emissions. As a first step in estimating health costs, a pooled cross-section time-series dataset is used to find the association between BMI and five countries, …
Economic Impacts Of Increased Corporate Average Fuel Economy (Cafe) Standards, Ann K. Hunter-Pirtle
Economic Impacts Of Increased Corporate Average Fuel Economy (Cafe) Standards, Ann K. Hunter-Pirtle
Department of Agricultural Economics: Dissertations, Theses, and Student Research
The Renewable Fuel Standard (RFS) mandates that U.S. transportation fuel producers blend specific volumes of ethanol and other biofuels with fossil fuels to spur U.S. biofuel production and to minimize foreign oil imports. Ethanol is more corrosive to auto engines than gasoline, and although vehicles manufactured since 2001 are approved to use up to a 15% ethanol blend (E15) (Naylor & Falcon, 2011), E10 is much more widely available. Ethanol producers therefore face a so-called blend wall at 10 percent—a maximum amount of ethanol that is usable domestically based on the demand for gasoline.
Meanwhile, gasoline demand in the U.S. …
Three Essays On Renewable Energy, Kepifri Alpha Lakoh
Three Essays On Renewable Energy, Kepifri Alpha Lakoh
Department of Agricultural Economics: Dissertations, Theses, and Student Research
This dissertation studies three main issues related to renewable energy in the United States and in Sub Sahara Africa.
The first chapter seeks to provide answers to a very fundamental question for second generation biofuels: “How much crop residue can farmers harvest from their fields for sale to cellulosic ethanol companies without affecting current levels of production?” The model developed is applied to 101 counties from four Midwestern states in the United States (Colorado, Iowa, Nebraska and Wyoming). Results show that soil organic matter significantly contributes to explaining changes in technical efficiency and total factor productivity. Furthermore, average crop …
Agricultural Productivity Growth In Central America And The Caribbean, Ayako Ebata
Agricultural Productivity Growth In Central America And The Caribbean, Ayako Ebata
Department of Agricultural Economics: Dissertations, Theses, and Student Research
This thesis estimates total factor productivity (TFP) growth in the agricultural sector of fourteen regions in Central America and the Caribbean. First, TFP is measured parametrically and non-parametrically, using the Ordinary Least Square (OLS) method and the Maximum Likelihood (ML) method to estimate a translog production function and the Malmquist index approach. Secondly, the thesis incorporates an environmental bad, CO2 emissions from expansion of agricultural land by sacrificing forest area and estimates environmentally adjusted productivity (EAP) growth rates using an output distance function in order to assess how the growth of TFP rates changes when such a bad is …
Replacement Alternatives For Beef Cow Herds: An Analysis Of Retaining Non-Pregnant Cows, Trenton T. Bohling
Replacement Alternatives For Beef Cow Herds: An Analysis Of Retaining Non-Pregnant Cows, Trenton T. Bohling
Department of Agricultural Economics: Dissertations, Theses, and Student Research
A non-pregnant cow is a liability to a producer. Over the last four years, cow-calf producers have had an increased number of non-pregnant cows due to factors like environmental conditions and diseases like trichomoniasis. While most research has indicated that culling a non-pregnant female and replacing the cow with retained heifers, purchased heifers, or purchased cows are the only economic alternatives, recent trends in the cattle market have suggested that keeping a non-pregnant cow may also be an alternative.
Annual beef cow budgets were created based on typical Nebraska Sandhills conditions. Revenues and costs in these budgets vary according to …
