Energy Production, Distribution, And Pollution Controls: Combining Engineering And Economic Analysis To Enhance Efficiency And Policy Design, David F. Perkis
Energy Production, Distribution, And Pollution Controls: Combining Engineering And Economic Analysis To Enhance Efficiency And Policy Design, David F. Perkis
Open Access Dissertations
Three published articles are presented which focus on enhancing various aspects of the energy supply chain. While each paper adopts a different methodology, all three combine engineering data and/or techniques with economic analysis to improve efficiency or policy design within energy markets. ^ The first paper combines a chemical engineering plant design model with an economic assessment of product enhancements within an ethanol production facility. While a new chemical process is shown to achieve greater ethanol yields, the animal feed by-products are denatured and decrease in value due to the degradation of a key nutritional amino acid. Overall, yield increases …

Profit-Maximizing Responses To Climate Change In Commodity Agriculture: Does Adaptation Matter?, Sajeev Erangu Purath Mohankumar
Open Access Theses
Accumulation of greenhouse gases in the atmosphere has led to rising temperatures, and is expected to lead to a change in climate. Crop yields are vulnerable to these changes. Adaptation is expected to be key to combating climate change impacts, but the effectiveness of adaptation strategies is not well understood. Hence, there is a need to assess the impacts of climate change on agriculture and devise profitable adaptation strategies to combat its effects. This study uses historical and three projected climate data sets to simulate yields using the crop model Daycent, empirical relationships between weather and agronomic variables that influence …
Producer Perceptions Of Their Use Of Time And Various Areas Of Risk In Their Business, Kendra Marie Hedge
Producer Perceptions Of Their Use Of Time And Various Areas Of Risk In Their Business, Kendra Marie Hedge
Open Access Theses
Agribusinesses rely on producers choosing their products and services for the success of their business. Agribusinesses can use information regarding how producers rate the importance of certain areas of risk and what takes most of the producers' time to offer specific services to different segments of producers to better meet their needs. An ordered logit model and a multinomial logit model are used to determine factors significant to producers' use of time and importance of various areas of risk. The producers are then segmented into groups based on their risk perceptions. From this research, agribusinesses can recognize that different types …
Quality And Safety Attributes Of Sun-Dried Raisins From Afghanistan, Stacy A. Mccoy
Quality And Safety Attributes Of Sun-Dried Raisins From Afghanistan, Stacy A. Mccoy
Open Access Theses
Raisins are an important export commodity for Afghanistan, however, Afghan packers are challenged to export to markets seeking high quality products due to limited knowledge regarding their quality and safety. To evaluate this, Afghan raisin samples from pre-, semi-, and post-processed raisins were obtained from a raisin packer in Kabul, Afghanistan. The raisins were analyzed and compared to U.S. standards for processed raisins. The samples tested did not meet U.S. import standards for embedded sand, but the process used to clean the raisins is suitable to maintain food safety standards.
Previous Afghan raisin shipments have been rejected from the U.S. …
Competition Between Private Labels And National Brands: Empirical Evidence From Homescan Data On Fluid Milk Markets, Jeffrey S. Young
Competition Between Private Labels And National Brands: Empirical Evidence From Homescan Data On Fluid Milk Markets, Jeffrey S. Young
Open Access Theses
The purpose of this study is to empirically examine the nature of the pricing relationship between private labels (or "store brands") and national brands. To accomplish this, we control for the exogenous variation in the farm price of a commodity that serves as the main agricultural input common to both private labels and national brands (any shocks to this farm price will pass through to both retail prices - private label and retail). The product of choice is fluid milk, as the farm price of milk comprises a large share of producer and retailer cost.
Two examples of underlying theories …
Market Power Estimation In The Chilean Cattle Market, Rodirgo A. Vasquez Panizza
Market Power Estimation In The Chilean Cattle Market, Rodirgo A. Vasquez Panizza
Open Access Theses
The cattle market in Chile is constituted by cattle slaughtering firms and farmers; the industry demands cattle but also demands beef imports. Based in antecedents of market concentration in this sector, I make a system of equations model based on the NEIO approach to determine market power for the period April 1993 - December 2008. The results show that there is no market power in the aggregated market as well as in the disaggregated market by sex and age type, which is explained because the special features of this market in Chile.
Us Commodity Support Payments: On Allocation Of Resources And Fairness, Post 1996, Samiul Haque
Us Commodity Support Payments: On Allocation Of Resources And Fairness, Post 1996, Samiul Haque
Open Access Dissertations
This dissertation investigates the effect of US commodity support payment on agricultural producer decisions during the "decoupled" regime. Particular attention is paid to the national optimal output mix, input proportions, and farm level changes in scale operations. While "decoupled" payments were instated to comply with WTO guidelines, where tax payer dollars cannot be spent to alter agricultural outputs and /or on farm input decisions, evidence suggests that such payments are far from being decoupled. At the national level, this dissertation finds evidence for mild labor input using and capital input economizing behavior. Substantial land input economizing behavior and moderate material …
Uncertainty, Irreversibility, And Investment In Secondgeneration Biofuels, Tanner Joseph Mccarty
Uncertainty, Irreversibility, And Investment In Secondgeneration Biofuels, Tanner Joseph Mccarty
Open Access Theses
The present study formalizes and quantifies the importance of uncertainty for investment in a corn-stover based cellulosic biofuel plant. Using a real options model we recover prices of gasoline that would trigger entry into the market and calculate the portion of that entry trigger price required to cover cost and the portion that corresponds to risk premium. We then discuss the effect of managerial flexibility on the entry risk premium and the prices of gasoline that would trigger mothballing, reactivation, and exit. Results show that the risk premium required by plants to enter the second-generation biofuel market is likely to …

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. …
