Economic Impacts Of Abolishing Vertical Integration In The Us Pork Industry, Konstantinos Giannakas

Department of Agricultural Economics: Presentations, Working Papers, and Gray Literature

This paper develops a multi-market framework of analysis of vertical relationships in pork production and game theoretic models of heterogeneous firms to examine the economic, market and welfare impacts of abolishing vertical integration in the US pork sector. Different scenarios on the causes of vertical integration and the potential states of nature that can emerge after the removal of this vertical market arrangement are considered within this framework. Analytical results are consistent across the different scenarios and forms of strategic interactions between pork producers and indicate that the abolishment of vertical integration in the US pork sector will hurt pork …

Genetically Modified Crops In Africa: Evidence On Adoption, Economic Benefits, Environmental Effects, And Constraints, Aloyce Hepelwa, Innocensia John

Tanzanian Economic Review

Africa faces deep food insecurity with over 300 million undernourished people driven by, low agricultural productivity, and climate shocks. To enhance food production and sustainable development, there is potential seen in genetically modified (GM) crops. To explore the potential of GM crops, this paper examines their production, adoption, economic and environmental impacts, adoption barriers, and policy implications in Africa and globally. This is done using a structured narrative review of peer-reviewed literature, reports, and policy documents (2014–2024) sourced from different databases complemented by stakeholder consultations. The findings show that GM has expanded considerably worldwide driven by high productivity, reduced pesticide …

Adaptation For Whom? Understanding The Impacts Of Dyke Policies On Small-Scale Farmers In Ca Mau Province Of Vietnam, Nguyen Minh Quang, Nguyen Van Minh, Nguyen Vo Chau Ngan, Martha B. Lerski

Publications and Research

Low-lying deltas worldwide are extremely vulnerable to sea-level rise. As the risks of climate-induced flooding become increasingly clear, the thirst for infrastructure-driven adaptation increases. This highlights a patent need to understand the impacts of engineering adaptation solutions, especially those targeting built structures such as dykes and sluices, on farmers from a bottom-up, farmer-centred perspective. The study addresses this call by examining cases where dyke policies, while successful in some dimensions, have undermined small-scale farmer livelihoods in Ca Mau ― Vietnam’s southernmost rural province. It identifies areas in need of attention and adds empirical data related to this group of farmers. …

The purpose of this study was to examine the status of the seaweed aquaculture industry along the West Coast of the United States; specifically in the states of California, Oregon, and Washington. Seaweed farmers in these states were invited to voluntarily complete surveys asking important production, economic, and commercial questions regarding their operations. Data …

The Impact Of Health And Environmental Messaging With And Without Product Filtering In Complex Retail Markets: The Case Of Pulses, Christopher R. Gustafson, Henriette Gitungwa, Sushil C. Sapkota, Devin J. Rose

Department of Agricultural Economics: Faculty Publications

Introduction: Multiple barriers exist to healthy and environmentally sustainable food choices. Limited consumer understanding of the health and environmental implications of food choices complicates their abilities to make choices that lead to desired outcomes. The complexity of the retail environment itself may crowd out less immediate motivations to address health or environment. Even if consumers understand general impacts of food choices on health and environmental outcomes, there may be non-negligible time and search costs to identifying the products that meet consumers’ needs. In many food categories, the foods containing attributes that help achieve health and sustainability outcomes may represent …

Coffee In Brasil: Sustainability And The Role Of Intermediaries, Livia Petzinger

Capstone Collection

ABSTRACT

Coffee is traded in a highly complex global value chain where countless sustainability initiatives have emerged to address social, economic, and environmental issues, challenges which persist due to dominance of the market structure by largescale traders and roasters. Specialty coffee and direct trade have emerged as alternative trade arrangements that promote high-quality coffee through the use of sustainable practices, transparency, and a shortened supply chain. This research analyzes the role that intermediaries in the Brazilian specialty coffee supply chain play in the implementation of sustainability initiatives asking what kinds of sustainability practices they implement and why, and how this …

Three Essays In Food Security And The U.S. Sugar Program, Jacob Michels

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Chapter one devises an approach to adjust estimates of the number of food insecure for changes in sedentarism over time. Existing methodologies are biased upwards and date back several decades. We build a household model utilizing a Stone-Geary utility function, which rationalizes households shifting their labor decisions towards sedentary activities. Our comparative statics examine the impacts of changes in the productivities of sedentary types, as opposed to my physically demanding types, of activities and also their returns. Our empirical approach is informed by our theoretical model and comparative statics, in which we construct a unique pseudo-panel dataset. Sitting time serves …

Department of Agricultural Economics: Faculty Publications

The objective of this study was to evaluate growth and reproductive performance of heifers developed using 3 different winter systems in the midwestern U.S. Spring-born heifers (n = 1,156; 214 d of age; SD ± 17 d) were used in a 3-yr study to evaluate performance in winter development systems, which utilized cover crop (CC) and corn residue grazing. Heifers were assigned to 1 of 3 treatments: grazing corn residue with 0.77 kg/d dried distillers grains (CD) or 1.69 kg/d wheat midds (CW) supplementation followed by a grower ration in the drylot, or grazing late summer planted oat-brassica CC followed …

Economic Research On Ethanol Feed-Use Coproducts: A Review, Synthesis, And Path Forward, Elliott James Dennis, Daniel Gertner, Galen E. Erickson

Department of Agricultural Economics: Faculty Publications

During the mid-2000s to the early 2010s, the domestic ethanol industry witnessed substantial growth, with ethanol coproducts emerging as vital elements for plant profitability and livestock feeding. Initially serving as supplementary revenue streams, coproducts from ethanol production have evolved into diverse value-added offerings, bolstering revenue streams, and sustaining profit margins. This study reviews existing economic research on ethanol coproducts, detailing methodologies, product focus, and research locations. Initially gathering 972 articles from 9 databases, 110 articles were synthesized. We find that most studies primarily examined the growth and future of the ethanol industry with a limited focus on specific coproducts. Feed-use …

Health Prompts Affect Consideration Of Health But Not Intertemporal Preferences While Promoting Healthier Food Choices, Olivier Tuyizere, Christopher Gustafson, Devin J. Rose

Department of Agricultural Economics: Faculty Publications

Diet-related diseases impact populations across the globe. While intertemporal preferences—a fundamental preference for the distribution of benefits across time—have been used to explain low-quality food choices, the recent literature proposes another cause: inattention to the future implications (or opportunity costs) of the options faced. Food choices tend to become habitual to conserve cognitive resources, rather than carefully modeling future health impacts. Both low discount rates for future benefits and attention to future health impacts predict healthier decisions. While intertemporal preferences are stable, attention may provide an opportunity to intervene in the decision process to promote healthier decisions. In this study, …

The Economic Impacts Of Social Activism And Corporate Social Responsibility On Food Fraud, Anubrata Deka, Amalia Yiannaka, Konstantinos Giannakas

Department of Agricultural Economics: Faculty Publications

The study examines the relationship between the corporate social responsibility (CSR) investments of a food firm, an activist’s incentive to target the firm to uncover and deter fraudulent behavior, and the firm’s incentive to commit food fraud. Specifically, we develop a game theoretic model to analyze the strategic interaction between a food firm that decides whether to provide a credence food attribute and whether to misrepresent the quality of its product, and an activist who decides whether to monitor the firm and launch a campaign to uncover and remove false/misleading quality claims. We further examine the effect of CSR and …

Can Machine Learning Models Provide Accurate Fertilizer Recommendations?, Takashi S. T. Tanaka, Gerard B. M. Heuvelink, Taro Mieno, David S. Bullock

Department of Agricultural Economics: Faculty Publications

Accurate modeling of site-specific crop yield response is key to providing farmers with accurate site-specific economically optimal input rates (EOIRs) recommendations. Many studies have demonstrated that machine learning models can accurately predict yield. These models have also been used to analyze the effect of fertilizer application rates on yield and derive EOIRs. But models with accurate yield prediction can still provide highly inaccurate input application recommendations. This study quantified the uncertainty generated when using machine learning methods to model the effect of fertilizer application on site-specific crop yield response. The study uses real on-farm precision experimental data to evaluate the …

Synthesis Of Current Evidence On Factors Influencing The Suitability Of Synthetic Biodegradable Mulches For Agricultural Applications: A Systematic Review, Michael Madin, Katherine Nelson, Kanji Fatema, Karina Schoengold, Abhilekha Dalal, Ikenna Onyekwelu, Rushrukh Rayan, Sanaz Saki Norouzi

Department of Agricultural Economics: Faculty Publications

Mulching practice offers farmers an opportunity to minimize the effects of drought, water loss, and soil erosion on crop production. Plastic film is widely used as a mulching material; however, contamination of arable lands by residual plastic has become a serious concern. Synthetic biodegradable mulch films and sprays may offer a more sustainable alternative to plastic films, however current evidence on the factors that influence the suitability of these products for agricultural applications is fragmented, making it unclear under what conditions these products meet agronomic, environmental, and societal needs. We address this gap by conducting a systematic review of studies …

Reducing Food Scarcity: The Benefits Of Urban Farming, S.A. Claudell, Emilio Mejia

Journal of Nonprofit Innovation

Urban farming can enhance the lives of communities and help reduce food scarcity. This paper presents a conceptual prototype of an efficient urban farming community that can be scaled for a single apartment building or an entire community across all global geoeconomics regions, including densely populated cities and rural, developing towns and communities. When deployed in coordination with smart crop choices, local farm support, and efficient transportation then the result isn’t just sustainability, but also increasing fresh produce accessibility, optimizing nutritional value, eliminating the use of ‘forever chemicals’, reducing transportation costs, and fostering global environmental benefits.

Spatially Coordinated Conservation Auctions: A Framed Field Experiment Focusing On Farmland Wildlife Conservation In China, Zhaoyang Liu, Simanti Banerjee, Timothy N. Cason, Nick Hanley, Qi Liu, Jintao Xu, Andreas Kontoleon

Department of Agricultural Economics: Faculty Publications

How best to incentivize land managers to achieve conservation goals in an economically and ecologically effective manner is a key policy question that has gained increased relevance from the setting of ambitious new global targets for biodiversity conservation. Conservation (reverse) auctions are a policy tool for improving the environmental performance of agriculture, which has become well-established in the academic literature and in policy making in the US and Australia. However, little is known about the likely response of farmers to incentives within such an auction to (1) increase spatial connectivity and (2) encourage collective participation. This paper presents the first …

Beef And Dairy Substitution Effects Associated With Carbon Labeling And An Information Intervention, Sara Gardner Hedgecock

Graduate Theses and Dissertations

Understanding consumer perceptions of carbon emissions in agriculture is a critical step to help increase the sustainability of food consumption. According to the Food and Agriculture Organization of the United Nations, 14.5 percent of all global anthropogenic GHG emissions are estimated to be represented by livestock (FAO), and cattle, raised for beef and milk, are the largest animal species responsible for emissions, comprising over 60 percent of the livestock sector’s emissions. This motivates this study’s analysis of beef and dairy milk products and alternatives. To better understand how consumers may substitute meat and milk products when provided with information about …

Department of Agricultural Economics: Faculty Publications

Humanity is facing complex challenges posed by population growth, climate change, and the need to increase food, feed, fiber, and bioenergy production while confronting the scarcity of natural resources. The transition to a circular economy, characterized by reduced resource use and waste, is being increasingly recognized in academic, business, and policy making circles as essential to meeting these challenges, with the emphasis being on the development of methods and processes that enable and facilitate the transition from a linear to a circular economy. This paper argues the need for an increased emphasis on the economics of the circular economy and …

Emotional Responses To Covid-19 Stressors Increase Information Avoidance About An Important Unrelated Health Threat, Christopher Gustafson, Kate Brooks, Syed Imran Ali Meerza, Amalia Yiannaka

Department of Agricultural Economics: Faculty Publications

The COVID-19 pandemic, like other crises, has had direct and indirect impacts on individuals, many of which have been negative. While a large body of research has examined the impacts of COVID-19 on people’s lives, there is little evidence about how COVID-19 affects decision-making broadly. Emotional responses to COVID-19-related stressors, such as illness and income loss, provide a pathway for these stressors to affect decision-making. In this study, we examine linkages between exposure to COVID-19-related stressors—focusing on temporally specific local case counts and loss of income due to the pandemic—and decisions to access information about antimicrobial resistance (AMR), another critically …

Department of Agricultural Economics: Faculty Publications

On-farm experimentation (OFE) is increasing worldwide. Appropriate OFE procedures may differ depending on the characteristics and circumstances surrounding farms, such as climate, field conditions, farm size, degree of agricultural digitalization, and a farmer’s socioeconomic background. This study aims to guide the future development of OFE in Japanese grain farming by examining the experimental setup, data analysis, and farmers’ activities within their socioeconomic and institutional communication and learning networks. The results of this typical OFE case study, which estimates a field’s economicallyoptimal fertilizer variable-rate application map for winter wheat production, are reported. The outcomes of the case study, which are intended …

Forced Labor Found Within The Supply Chains Of The Coffee Industry, Hollis Deuschle

Supply Chain Management Undergraduate Honors Theses

I have focused my research on the morality within supply chains that source major coffee companies around the world. As consumers, many of us have no idea where the products that we use everyday truly come from. The purchases we make have the power to feed into the issue of forced labor. The coffee we buy often does. My thesis takes a look into the extensive issue of human trafficking and unjust labor practices on the plantations that provide us with the coffee we sip on each morning. This paper serves to enlighten producers and consumers on this phenomenon, to …

An Assessment Of Information And Education As A Factor Of Agricultural Development And Sustainability In South Carolina, George Strickland

All Theses

Across the Southeastern United States, producers in the agricultural industry wage a constant struggle between combating negative economic impacts and discovering economic opportunity. Harmful Algal Blooms (HABs) represent a crisis with wide-ranging economic impacts. The management of HABs presents a critical challenge for addressing the level of knowledge (LOK) and adaptability of Extension agents. Conversely, the emergence of markets for local and organic produce represents a burgeoning economic opportunity for producers. The growing trend of including more kale in the everyday American diet demands an assessment of those opportunities for local producers.

To identify the WTP for organic and local …

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 …

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 …

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 …

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 …

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 …
