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 …

The Effect Of The Environmental Protection Agency’S Exhaust Emissions Standards On Diesel Tractor Fuel Efficiency, Jerin Tekolste

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

Since its inception the U.S. Environmental Protection Agency (EPA) has been tasked with the assessment, research, and education, of the nation’s environment while also maintaining and enforcing national standards. A characteristic display of this agency’s work is the Exhaust Emission Standards for Nonroad Compression-Ignition Engines that began in 1995. Since the introduction of exhaust emissions standards in 1995, no study has fully examined the subsequent impact on fuel efficiencies.

In this paper we analyze the resulting fuel efficiency caused by the EPA’s exhaust emission standards. We identify the impact of the emissions standards on tractor fuel efficiency through a statistical …

Things To Consider Before Co-Signing A Loan, J. David Aiken

Cornhusker Economics

In the context of family farms, includes some general points to consider before you sign a loan guarantee for a family member who is heavily in debt.

Conclusion: Having to consider whether to co-sign a child's loan is a very difficult situation-no one wants to be part of losing part of the family farm or ranch to loan foreclosure. But if the loan guarantee isn't part of a financial turnaround plan that has at least a fighting chance of success, don't sign the guarantee unless you absolutely don't need the money for your own retirement.

Deficit Irrigation Management For Irrigated Corn In Nebraska: Economically Viable?, Lia Nogueira, Cory Walters, Emily O'Donnell, Wesley Peterson, Suat Irmak

Cornhusker Economics

In this study we determine the economic value of deficit irrigation management using both technological and methodological advancements. The use of soil moisture probes represents the technological improvement. We provide improvements in the methodology as follows. Regarding data, we employ a field-size study, instead of plots, where the irrigation decision is determined by the moisture level in the soil measured through a soil moisture probe. Regarding the understanding of the yield response to water, although we examine the commonly used quadratic function, we improve upon this specification by also examining an alternative response function, the linear response stochastic plateau. Our …

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 …

Nebraska Farmland Values And Cash Rental Rates In 2023, Jim Jansen, Jeffrey Stokes

Cornhusker Economics

The market value of agricultural land in Nebraska increased by 14% over the prior year to an average of US $3,835 per acre, according to the 2023 Nebraska Farm Real Estate Market Survey. This marks the second-largest increase in the market value of agricultural land in Nebraska since 2014 and the highest non-inflation-adjusted state-wide land value in the 45-year history of the survey.

The University of Nebraska-Lincoln’s Department of Agricultural Economics annually surveys land industry professionals across Nebraska, including appraisers, farm and ranch managers, agricultural bankers, and related industry professionals. Results from the survey are divided by land class and …

Comparing Cover Crop Research In Farmer-Led And Researcher-Led Experiments In The Western Corn Belt, Katja Koehler-Cole, Andrea D. Basche, Laura J. Thompson, Jennifer M. Rees

Nebraska Extension: Faculty and Staff Publications

Cover crops can mitigate soil degradation and nutrient loss and can be used to achieve continuous living cover in cropping systems, although their adoption in the Western Corn Belt of the United States remains low. It is increasingly recognized that cover crop integration into corn (Zea mays L.)-based crop rotations is complex, requiring site and operation specific management. In this review, we compared on-farm, farmer-led field scale trials to researcher-led trials carried out in small plots on University of Nebraska-Lincoln experiment stations. Although there is a range of cover crop research conducted in the state, there is no …

The Trade Impact Of Economic Integration Agreements, Byungyul Park, John C. Beghin

Cornhusker Economics

A year ago, Cornhusker Economics reported on the substantial trade integration that has been taking place globally in recent decades (see Beghin, 2022). With this proliferation of Economic Integration Agreements (EIAs) through regional and bilateral trade agreements and customs unions since the 1990s, many economists have investigated the effect of these agreements on merchandise trade. Early investigations struggled to find robust findings. They reached two opposite conclusions, with an eventual rejoinder on their limitations. Some investigations found statistically insignificant or negligible effects of EIAs on trade flows. Other investigations found significant effects, sometimes negative, of EIAs on trade. See Park …

Economics Of Deficit Irrigation Utilizing Soil Moisture Probes In The Western Corn Belt, Emily O’Donnell, Lia Nogueira, Cory Walters, E Wesley F. Peterson, Suat Irmak

Department of Agricultural Economics: Faculty Publications

Effective irrigation management is critical for future food supplies and the prosperity of producers engaged in irrigation production. Through a deficit irrigation field experiment, we determine the financial impact on producers caused by changing irrigation costs, corn prices, extreme weather events, and restricting irrigation levels. Results suggest that the optimal economic strategy within our constrained optimization model is to fully irrigate, with the economic impact highly dependent on commodity prices, restriction level, and irrigation costs. The greatest economic losses caused by irrigation restrictions come from decreases in yield. Some simulations resulted in negative profits, indicating that a switch to alternative …

Cover Crop Planting Practices Determine Their Performance In The U.S. Corn Belt, Katja Koehler-Cole, Roger W. Elmore, Humberto Blanco-Canqui, Charles A. Francis, Charles A. Shapiro, Christopher A. Proctor, Sabrina J. Ruis, Suat Irmak, Derek M. Heeren

Nebraska Extension: Faculty and Staff Publications

Cover crop growing periods in the western United States Corn Belt could be extended by planting earlier. We evaluated both pre-harvest broadcast interseeding and post-harvest drilling of the following cover crops: (a) cereal rye (Secale cereale L.) [RYE]; (b) a mix of rye + legumes + brassicas [MIX1], (c) a mix of rye + oat [Avena sativa L.] + legumes + brassicas (MIX2), (d) legumes [LEGU]) and (e) a no cover crop control. These were tested in continuous corn (Zea mays L.) [corn–corn] and soybean [Glycine max (L.) Merr.]–corn systems [soybean–corn] at three sites in Nebraska …

The Impact Of Organized Activism On Technology Sharing, Ahmed Chennak, Amalia Yiannaka

Cornhusker Economics

What factors influence a firm's decision to share its technology with competitors? While patent licensing has received considerable attention in the literature, studies have typically focused on the optimal licensing contract for product and process innovations in various market settings. A key finding of this literature is that the optimal licensing strategy depends on the type of the patentee; that is, whether the patentee is a producer in the market (insider patentee) or not (outsider patentee). Little attention has been given, however, to the role the general public can play on firms' incentives to share their innovations through licensing contracts …

Role Of Social Network On Technology Adoption: Application To Nebraska Producers In The Face Of Undesirable Vegetation Transitions, Sabrina Gulab, Holly K. Nesbitt, Simanti Banerjee, Theresa Floyd

Cornhusker Economics

Conclusion

Producers need to have access to information regarding new conservation practices and technologies to ensure land management in the face of ecological threats in general and vegetation transitions (VTs) in the context of our study. This study investigates the role of an individual producer's social network on the willingness to seek information about technologies and management practices and the likelihood of new technology adoption with special attention to risk attitudes and producer spillover effects. Our results provide evidence that network composition and information obtained through a producer's social network don't influence an individual's willingness to seek information about new …

Dissemination Of Agro-Based Information By Telecentres Among Selected Rural Farmers In Tanzania With A Focus On Moshi Rural District, Kilimanjaro Region, Neema Florence Mosha Dr, Edith Talina Luhanga Dr, Pascal Nade Dr, Patrick Ngulube Prof

Library Philosophy and Practice (e-journal)

The study assessed the role of Telecentres in the dissemination of agro-based information among selected farmers in rural areas of Tanzania. A cross-sectional study design was conducted in Moshi Rural District, in Kilimanjaro Region, Tanzania. A total of 442 rural farmers aged 21-60 years were randomly selected as study respondents. Questionnaires were used to collect data from respondents. The study found that 205 (55%) respondents were not aware of the existence and services offered among Telecentres, whereas only 12 (7%) respondents reported visiting Telecentres once per day, and 70 (41%) once per year. A total of 140 respondents selected computer …

The Role Of Behavioural Factors And Opportunity Costs In Farmers' Participation In Voluntary Agri-Environmental Schemes: A Systematic Review, Sergei Schaub, Jaboury Ghazoul, Robert Huber, Wei Zhang, Adelaide Sander, Charles Rees, Simanti Banerjee, Robert Finger

Department of Agricultural Economics: Faculty Publications

Agri-environmental schemes (AESs) are increasingly implemented to promote the adoption of environmentally friendly practices by farmers. We use a systematic review to explore the role of behavioural factors and opportunity costs in farmers' decisions to participate in AESs in Australia, Europe and North America. Behavioural factors influence how farmers value and perceive options, while opportunity costs relate to farmers' forgone utility when choosing to participate in schemes. We synthesise insights from 79 articles and over 700 factors explaining the participation in AESs. We find that a set of behavioural factors seem consistently connected to participation, including agricultural training, advice and …

Evaluating The Relative Impact Of Multiple Healthy Food Choice Interventions On Choice Process Variables And Choices, Christopher Gustafson

Department of Agricultural Economics: Faculty Publications

Fiscal tools—taxes and/or subsidies—are increasingly used to address diet-related health problems. However, some studies have found that these tools are markedly more effective if attention is drawn to the tax or subsidy, suggesting that the price change alone may go unnoticed in the complex food environments that consumers face. Interventions that prompt individuals to consider health during choice show promise for promoting healthy food choices in both simple laboratory settings and complex, real-world markets. In this pre-registered study, I examine the impact of dietary fiber health prompts and/or dietary fiber subsidies on the per-serving fiber content of foods chosen, the …

Integrated Vs. Specialized Farming Systems For Sustainable Food Production: Comparative Analysis Of Systems’ Technical Efficiency In Nebraska, Maroua Afi, Jay Parsons

Department of Agricultural Economics: Faculty Publications

Complementarities between crops and livestock production have the potential to increase input use efficiency and maintain a diversified livelihood. This paper uses non-parametric data envelopment analysis (DEA) to assess the technical efficiency (TE) of integrated crop–livestock systems (ICLS) compared to specialized cropping and specialized livestock systems in the state of Nebraska, in the central United States. We classify each county of Nebraska into one of three systems according to their dominant agricultural production revenues. We use DEA to measure the TE of each county compared, first, to a group production frontier (in-system comparison) and second, to a metafrontier (cross-system comparison). …

Food Fraud: A Persistent Problem That Demands A Comprehensive Approach, Amalia Yiannaka

Department of Agricultural Economics: Faculty Publications

Food fraud commonly refers to the deliberate and economi­cally motivated adulteration and mislabeling of food, but more broadly defined it also includes food theft, simulation that makes a fraudulent food product look like the legiti­mate product it copies, diversion, and overrun (Moyer et al. 2017). It is a longstanding and persistent challenge that impacts the global food sector; according to some estimates, food fraud results in annual costs of $40 billion (Food Standards Agency 2020). The complexity of globalized agri-food supply chains which are long, fast-moving, and involve a large number of intermediaries, coupled with lax regulatory monitoring and oversight …

Importance Of Good Communications For Generational Ag Business Transfers, Allan Vyhnalek

Cornhusker Economics

Adapted from Right Risk, volume 10, Issue 10, October 2022.

Effective communication within a farm or ranch family, especially when multiple generations are operating and managing the business, is the underpinning of all other decisions made in a family business. It is critical that farm and ranch families identify areas of contention and develop communication skills that will allow them to negotiate satisfying outcomes. This may involve basic skills training, including communication, problem solving, and decision making.

Patterns Of Population Structure And Introgression Among Recently Differentiated Drosophila Melanogaster Populations, Jenn M. Coughlan, Andrius J. Dagilis, Antonio Serrato-Capuchina, Hope Elias, David Peede, Kristin Isbell, Dean M. Castillo, Brandon S. Cooper, Daniel R. Matute

Nebraska Extension: Faculty and Staff Publications

Despite a century of genetic analysis, the evolutionary processes that have generated the patterns of exceptional genetic and phenotypic variation in the model organism Drosophila melanogaster remains poorly understood. In particular, how genetic variation is partitioned within its putative ancestral range in Southern Africa remains unresolved. Here, we study patterns of population genetic structure, admixture, and the spatial structuring of candidate incompatibility alleles across a global sample, including 223 new accessions, predominantly from remote regions in Southern Africa. We identify nine major ancestries, six that primarily occur in Africa and one that has not been previously described. We find evidence …

Perceptions Of The Economy And Employment In Nonmetropolitan Nebraska: 2022 Nebraska Rural Poll Results, Rebecca J. Vogt, Heather Akin, Cheryl A. Burkhart-Kriesel, Bradley Lubben, L. J. Mcelravy, Timothy L. Meyer, Steven A. Schulz, Amanda Tupper

Nebraska Rural Poll

Most rural Nebraskans believe most of the listed economic items will become worse or much worse over the next 12 months when asked in May and June. Almost nine in ten think the following will become worse: inflation, gasoline or diesel fuel prices, grocery prices, and interest rates. In fact, at least four in ten rural Nebraskans believe the following items will become much worse in the next 12 months: gasoline or diesel fuel prices, inflation, grocery prices, and healthcare costs. The two items that had less than one-half believing they would become worse or much worse during the next …

The Role Of Intertemporal Preferences, Active Consideration Of Health Outcomes, And Simple Health Prompts On The Nutritional Quality Of Food Choices, Olivier Tuyizere

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

This thesis consists of three chapters. The first chapter introduces the thesis by highlighting a brief review of intertemporal preferences, active consideration of health outcomes, and health prompts during food choices. The introduction paves the way for the following two chapters, which are related, but stand-alone papers.

In the second chapter, we explore a novel question: how does actively considering health outcomes (both current and future) during decision-making affect the nutritional quality of food choices? We explore this question with an online experiment on food choices. Our findings show that active consideration of health outcomes leads to choosing products with …

New Plant Engineering Techniques, R&D Investment And International Trade, Stéphan Marette, Anne-Célia Disdier, Anastasia Bodnar, John C. Beghin

Department of Agricultural Economics: Faculty Publications

New plant engineering techniques (NPETs) may significantly improve both production and quality of foods. Some consumers and regulators around the world might be reluctant to accept such products and the global market penetration of these products may remain low. We develop a parsimonious economic model for R&D investment in food innovations to identify conditions under which NPET technology emerges in the context of international trade. The framework integrates consumers' willingness to pay (WTP) for the new food, the uncertainty of R&D processes, the associated regulatory cost of approval, and the competition between domestic and foreign products. With generic applicability, the …

Setting The Stage For The Next Farm Bill Debate, Bradley D. Lubben

Cornhusker Economics

The 2018 Farm Bill is set to expire in September 2023. New farm bill legislation will be needed by then if authority is to be extended for a wide range of programs from farm support to conservation, nutrition assistance, credit, trade promotion, rural development, research and education, and more.

The agricultural committees in Congress have already held initial hearings and many agricultural and other interest groups have noted their policy priorities. However, formal debate on a new farm bill is not expected to begin in earnest until early 2023 when a new session of Congress convenes.

While the formal debate …

Lessons Learned From The 2019 Nebraska Floods: Implications For Emergency Management, Mass Care, And Food Security, Eric E. Calloway, Nadine B. Nugent, Katie L. Stern, Ashley Mueller, Amy L. Yaroch

Nebraska Extension: Faculty and Staff Publications

This qualitative study aimed to understand the actions, challenges, and lessons learned for addressing the food and water needs of flood survivors, with a special focus on vulnerable populations and the implications for food security, to inform future disaster response efforts in the U.S. Semi-structured in-depth interviews were conducted from January to August 2020 with the local, state, and national stakeholders (n = 27) involved in the disaster response to the 2019 Nebraska floods, particularly those involved in providing mass care, such as food, water, and shelter, for the flood survivors. The challenge themes were related to limited risk …

Hybrid Incompatibility Between Ldrosophila Virilis And D. Lummei Is Stronger In The Presence Of Transposable Elements, Dean M. Castillo, Leonie C. Moyle

Nebraska Extension: Faculty and Staff Publications

Mismatches between parental genomes in selfish elements are frequently hypothesized to underlie hybrid dysfunction and drive speciation. However, because the genetic basis of most hybrid incompatibilities is unknown, testing the contribution of selfish elements to reproductive isolation is difficult. Here, we evaluated the role of transposable elements (TEs) in hybrid incompatibilities between Drosophila virilis and D. lummei by experimentally comparing hybrid incompatibility in a cross where active TEs are present in D. virilis (TE+) and absent in D. lummei, to a cross where these TEs are absent from both D. virilis (TE−) and D. lummei genotypes. Using genomic data, …

Active Consideration Of Health And Nutritional Quality Of Food Choices, Christopher R. Gustafson

Cornhusker Economics

Everyone can be positively influenced by effective interventions promoting healthier food choices. A handful of recent papers have documented positive impacts on dietary quality resulting from interventions that remind people to consider health through prompt messages or subtle priming in supermarkets and in controlled, online experiments. These studies have focused on the impact of reminders on nutritional quality rather than explaining how reminders work. An exception, Arslain, Gustafson, and Rose (2021), collected data on multiple elements of individuals' choice processes to trace the impact of reminders on decisions, showing that reminder messages led people to consider a healthier set of …
