Statistical Analysis Of The Adoption Of Conservation Practices In Midwest And Great Plains Agriculture, Regan Gilmore, Karina Schoengold

UCARE: Research Products

Improving conservation in conventional agriculture is crucial for the sustainability of agricultural economies. The aim of this project is to identify factors correlated with agricultural producers adopting conservation practices on their land.

Producers tend to choose their tillage and cropping systems based on soil management and yield/productivity concerns. Reasons and concerns for using no-till vary by state. For example, producers in Iowa choosing their tillage system based on yield/productivity concerns are 9.8% less likely to use no-till, while producers in South Dakota with the same concerns are 21.5% more likely to use no-till.

Agroforestry Standards For Regenerative Agriculture [Review], Craig R. Elevitch, D. Niki Mazaroli, Diane Ragone

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Agroforestry is increasingly being recognized as a holistic food production system that can have numerous significant environmental, economic, and social benefits. This growing recognition is paralleled in the USA by the budding interest in regenerative agriculture and motivation to certify regenerative practices. Current efforts to develop a regenerative agriculture certification offer an opportunity to consider agroforestry’s role in furthering regenerative goals. To understand this opportunity, we first examine how agroforestry practices can advance regenerative agriculture’s five core environmental concerns: soil fertility and health, water quality, biodiversity, ecosystem health, and carbon sequestration. Next, we review a subset of certification programs, standards, …

Sweet Sorghum As Feedstock In Great Plains Corn Ethanol Plants: The Role Of Biofuel Policy, Richard Perrin, Lilyan E. Fulginiti, Subir Bairagi, Ismail Dweikat

Department of Agricultural Economics: Faculty Publications

This research examines whether sweet sorghum, a crop considered more drought-tolerant and suitable for semi-arid areas than corn, could result in an economically viable sweet sorghum ethanol pathway in the Great Plains. We find that that if the D5–D6 RIN price spread exceeds the $0.35/gal recently experienced, the benefits of the pathway would be equivalent to about $90/acre of sweet sorghum, or $0.38/gal of ethanol. Because of sparse cultivation potential, only four the six existing plants in the Nebraska–Colorado High Plains area might expect transportation costs to be low enough for economic feasibility.

Input Use Under Crop Insurance: The Role Of Actual Production History, Taro Mieno, Cory Walters, Lilyan E. Fulginiti

Department of Agricultural Economics: Faculty Publications

The impact of crop insurance on changes in input use has attracted much attention by economists. While there are a number of studies on this topic, they frame moral hazard in inputs use in a static model. However, when agricultural producers are forward-looking, they would make input allocation decisions realizing that their decisions would affect their future actual production history. This, in turn, affects the probability and size of future indemnity payments. Thus, moral hazard should be framed in a dynamic input use decision model. We first show theoretically that under certain feasible conditions, a static analysis always results in …

Value Of Arrival Metaphylaxis In U.S. Cattle Industry, Elliott James Dennis, Ted C. Schroeder, David G. Renter, Dustin L. Pendell

Department of Agricultural Economics: Faculty Publications

Although several studies have estimated economic impacts of antimicrobials for growth promotion, little is known about economic impacts of the common animal health management strategy known as metaphylaxis: administering antimicrobials to groups of animals to prevent disease. This article develops a new framework to map animal disease to producer profitability and determine societal economic impacts surrounding metaphylactic use of antimicrobials in beef cattle production. Results indicate the direct net return value of metaphylaxis to the U.S. fed cattle industry is at least $532 million. Beef producer surplus losses of $1.8 billion would be associated with eliminating metaphylaxis.

The Impact Of Groundwater And Well Characteristics On Irrigator Energy Contract Choice, Taylor Hackbart

Department of Agricultural Economics: Dissertations, Theses, and Student Research

The thesis uses cross sectional data from the year 2009 to analyze irrigator choice of electricity contract. The data includes irrigators from the Midwest Electric Cooperative Corporation (MECC), which covers portions of three of Nebraska’s Natural Resource Districts (the Middle Republican, Twin Platte, and Upper Republican NRDs). Each of these institutions tries to reduce the pressure its users place on limited natural resources.

To accomplish this the MECC has established interruptible contracts with irrigators. These contracts allow the MECC to control the electricity supply for an irrigator’s well for a pre-determined number of days, which allows it to better manage …

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 …

A Nonparametric Frontier Measure Of Marketing Efficiency: An Illustration With Corn Ethanol Plants, Lilyan E. Fulginiti

Department of Agricultural Economics: Faculty Publications

This article extends nonparametric measures of efficiency to accommodate the concept of marketing efficiency, which measures changes in net revenues brought about by firms’ use of marketing channels other than spot markets. The measure is appropriate for firms operating under atomistic competition with imperfect information. The proposed measure displays two important features: (a) it uses the alternative of a spot price-based counterfactual to distinguish marketing from allocative efficiency, and (b) it allows for the fact that firms operate in different spot markets and have access to diverse sets of prices. We illustrate this approach with a unique dataset from ethanol …

Benefits Of Public R&D In U.S. Agriculture: Spill-Ins, Extension And Roads, S L. Wang, A Plastina, Lilyan E. Fulginiti, E. Ball

Department of Agricultural Economics: Faculty Publications

This paper uses panel data for the 1980-2004 period to estimate the contributions

of public research to US agricultural productivity growth. Local and social

internal rates of return are estimated accounting for the effects of R & D

spill-in, extension activities and road density. R & D spill-in proxies were constructed

based on both geographic proximity and production profile to examine

the sensitivity of the rates of return to these alternatives. We find that

extension activities, road density, and R & D spill-ins, play an important role

in enhancing the benefit of public R & D investments. We also find …

International Migration, E. Wesley F. Peterson

Cornhusker Economics

Labor is the world’s most valuable commodity—yet thanks to strict immigration regulation, most of it goes to waste. (Caplan and Naik, 2015) World economic output (currently about $75 trillion) could double if people were allowed to move freely in response to economic opportunities in other countries (Caplan and Naik, 2015). Workers in developing countries have very low productivity because they lack the capital and technology available in high-income countries. In addition, they live in countries in which the rule of law is often absent. Moving to high-income countries would increase their productivity substantially leading to much greater world economic output. …

The Role Of Safety First Risk Preferences In Grain Marketing: A Laboratory Economic Experiment Using A Grain Marketing Simulation Game, Stamatina Kotsakou

Department of Agricultural Economics: Dissertations, Theses, and Student Research

In this study, the Marketing in a New Era (MINE) grain marketing simulation game is used to carry out a context-rich economic experiment to evaluate the role of risk preferences in grain marketing decisions. The model of risk preferences that we consider is an improved Safety First decision rule model proposed by Levy and Levy (2009). We experimentally test if Safety First decision rule describes individuals’ post-harvest marketing decisions. In our experiment, we incorporate real-world features which are usually omitted in marketing studies such as: multiple storage decisions, storage cost, actual price series and multiple contract frequency. MINE plays a …

This thesis contributes to the literature of economics of small-scale fishery communities and fishery management in developing nations. In the first section we review literature on state of the fishery resource and the livelihoods in the globe and performance of fishery management systems in developing and developed countries. Second section discusses the results of an empirical study on the economics of subsistence fishers in Digha-Shankarpur in Eastern India. Results of the empirical study shows by-catch by the trawlers leads to the depletion of target fish stock of the subsistence fishers. Underutilization of the capacity by the subsistence fishers due to …

Measurement Of Commodity Price Risk: An Overview Of Brazilian Agricultural Markets, Daniel Henrique Dario Capitani, Fabio Mattos

Department of Agricultural Economics: Faculty Publications

This study explores different procedures to estimate price risk in commodity markets. Focusing on Brazilian agricultural markets, the paper proposes to assess both dispersion and downside risk measures using five different approaches (volatility, coefficient of variation, lower partial moments, value at risk and conditional value at risk). Results suggest that some commodities have large price variability but small downside risk, while other commodities show small price variability and large downside risk. Thus, there is no single answer to the question of which commodity exhibits more price risk, but rather distinct answers depending on how risk is perceived by different individuals. …

Geometry-Based Mass Grading Of Mango Fruits Using Image Processing, M. A. Momin, Md Towfiqur Rahman, M. S. Sultana, C. Igathinathane, A. T. M. Ziauddin, T. E. Grift

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Mango (Mangifera indica) is an important, and popular fruit in Bangladesh. However, the post-harvest processing of it is still mostly performed manually, a situation far from satisfactory, in terms of accuracy and throughput. To automate the grading of mangos (geometry and shape), we developed an image acquisition and processing system to extract projected area, perimeter, and roundness features. In this system, images were acquired using a XGA format color camera of 8-bit gray levels using fluorescent lighting. An image processing algorithm based on region based global thresholding color binarization, combined with median filter and morphological analysis was developed …

Consumer Perceptions Of Food Safety And Preferences For Food Safety Interventions, Kofi Britwum

Department of Agricultural Economics: Dissertations, Theses, and Student Research

This dissertation consists of three essays that investigate consumers’ response to technologies that mitigate food safety risks: cattle vaccines against E. coli and direct-fed microbials.

The first essay examines the influence of information framing and issue involvement on perceptions of the two food safety technologies. This essay also examines the role of issue involvement on food safety perceptions. A hypothetical survey which includes six information treatments was developed, and targeted a representative, random sample of U.S consumers. Participants were exposed to general information about E. coli and the two food safety technologies, a gain-framed message, a loss-framed message, …

Closing Abandoned Livestock Lagoons Effectively To Utilize Nutrients And Avoid Environmental Problems, Leslie J. Johnson, Charles Shapiro, Amy Schmidt

Nebraska Cooperative Extension: Faculty and Staff Publications

In Nebraska alone, nearly 400 earthen manure storage structures are in operation; approximately four dozen requests to cease operation of permitted lagoons were received by the Nebraska Department of Environmental Quality in the prior decade with many more non-permitted storage structures being in need of proper closure. Abandoned livestock lagoons, earthen manure storage basins, and other manure storages (e.g. concrete pits) need to be decommissioned in a manner that controls potential environmental risk and makes economical use of accumulated nutrients. Currently, limited guidance is available to support lagoon closure planning and implementation and few professionals who support livestock producers have …

Empathy Conservation: Experiments Suggest A Need For More Attention In Policymaking, Natalia V. Czap, Hans J. Czap, Gary Lynne, Mark E. Burbach

CAFIO: Policy Research Group Policy Pagers

One of the major challenges of environmental policy with regard to conservation is that it must often rely on voluntary and non-selfish actions of individuals. Traditionally policy makers rely on direct regulation and financial incentives, but both approaches face problems. Regulations may lead to resentment and the costs of perfect enforcement are prohibitively high. Financial incentives can be perverse and may lead to unintended consequences, including crowding out of intrinsic motivation. In addition, behavioral economics and economic psychology studies demonstrate that the assumptions of the neoclassical economic models (such as self-interest only, rationality, and willpower) on which the policy design …

Renewable Portfolio Standards May Reduce Green Energy Used In Electricity Production, Karina Schoengold, Suparna Bhattacharya, Konstantinos Giannakas

CAFIO: Policy Research Group Policy Pagers

Rising energy prices, dependence on foreign oil supplies, and consequences of climate change have prompted governments worldwide to initiate policies to shift from fossil fuels to renewables for electricity generation. One of the most commonly used policy instruments is the Renewable Portfolio Standard (RPS), which requires electricity providers to procure green energy (e.g., wind, solar, biomass) for a portion of their electricity supplies. To date, RPS has been a state-mandated program in the United States. As of February 2017, 29 states, Washington DC, and 3 territories have adopted RPS policies.

Has The Usage Of Precision Agriculture Technologies Actually Led To Increased Profits For Nebraska Producers?, Michael H. Castle

Department of Agricultural Economics: Dissertations, Theses, and Student Research

An ever-increasing global demand for food, coupled with increasingly volatile commodity prices have charged producers with the task of becoming more efficient. As such, technologies aimed at producing more with less are continually being developed and marketed to producers. However, whether or not these expensive new technologies have resulted in improved profitability is still unknown, as the vast majority of studies showing their impact on profitability have been performed using hypothetical farms and simulations. These studies have shown the potential for increases in profitability from use, but their impact in the real world is still uncertain.

This project uses various …

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 …

Assessing The Ability Of Rural Electric Cooperatives To Retire Capital Credits, Jeffrey S. Royer

Department of Agricultural Economics: Faculty Publications

This paper assesses the ability of rural electric cooperatives to retire member equity under three strategies: (1) replacing equity with term debt to provide for an immediate one-time retirement of capital credits, (2) reducing the rate at which equity is accumulated and relying more on term debt to finance asset growth so margins can be used to accelerate the retirement of capital credits, and (3) adjusting the electric rate to generate additional margins for retiring capital credits. Analyses suggest that the average distribution cooperative could employ these strategies to expand capital credits retirement substantially without weakening its financial condition.

Perceptions Of Well-Being In Nonmetropolitan Nebraska: 2016 Nebraska Rural Poll Results, Rebecca Vogt, Cheryl Burkhart-Kriesel, Randolph Cantrell, Brad Lubben, Larry J. Mcelravy Jr.

Publications from the Center for Applied Rural Innovation (CARI)

Certain indicators have pointed to overall economic growth in Nebraska. The state’s unemployment rate has remained among the lowest in the nation and wages have increased. However, net farm income continued to decline last year and employment growth in the state has been largely concentrated in the metropolitan counties. Given the challenges and uncertainties of recent years, how do rural Nebraskans believe they are doing and how do they view their future? How satisfied are they with various items that influence their well-being? Have these views changed over the past 21 years? This paper provides a detailed analysis of these …
