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 …

Effect Of Beef Heifer Development Systems Utilizing Corn Residue And Late Summer Planted Cover Crops On Growth, Reproductive Performance, And Economics, Hannah F. Speer, Robert A. Cushman, Harvey Freetly, Jay Parsons, Jessica Windh, M. E. Drewnoski

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 …

Exploring Producers' Willingness To Pay For Ecosystem Services: Three Essays On Soil Health, Location Preferences, And Cover Crop Adoption, Kaouter Essakkat

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

This dissertation comprises three essays: one assessing Midwest producers' willingness-to-pay (WTP) for soil health-enhancing ecosystem services (ES), another examining the impact of policy implementation locations on WTP, and a third identifying factors influencing producers' adoption of cover crops (CC).

The first essay pioneers the understanding of agricultural producers’ valuation of soil health-associated ES amid growing concerns of soil degradation due to agricultural intensification. Using a discrete choice experiment, this study assesses producers’ WTP for a policy that incentivizes ES provision, specifically improved water quality, carbon sequestration, and enhanced crop yield. Surveying producers across Iowa, Kansas, and Nebraska, our results show …

Violent Conflict Drives World Hunger And Food Insecurity, E. Wesley F. Peterson

Cornhusker Economics

The World Food Program (WFP) with support from the United States and other countries works to provide food to those in need as a result of conflict, adverse climate effects, poverty, and government mismanagement. It is limited in what it can do, however, by budget constraints and rising food prices. On top of the financial issues, the delivery of food assistance is particularly complicated in areas of conflict where warring adversaries often hijack food supplies intended for the other side. While it is illegal under International Humanitarian Law to use starvation as a weapon of war, Dzerowicz (2023) has identified …

Utilizing Extreme Value Theory To Uncover Yield Distributions From Farm And County Level Historical Corn Yields, Gerald H. Van Tassell

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

Yield risk represents a major portion of the financial risk facing corn producers and is found in the left tail of the yield distribution. Traditional methods for generating yield distributions fall into two categories: parametric and non-parametric. The shape and behavior of the tail of parametric yield distributions are determined by distributional assumptions. Non-parametric distributions fail to account for the possibility of as yet unseen extreme events, often referred to as “Black Swans”. Extreme Value Theory (EVT) rectifies these issues by providing an empirical, parametric estimate of the risk of extreme events, regardless of the underlying distribution of corn yields. …

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 …

Stories Of Motivation And Values Of Small-Scale Farmers In Jamaica And The United States, Raquel Taylor

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

Small-scale farmers add to global and local food systems through various means such as connecting communities to local food and support economies. Small-scale farms can address issues related to food and nutritional security. However, farming can be a challenging career to engage in, especially for those who are small-scale farmers. Matters related to succession, higher paying off-farm employment, policies, and more can make it challenging to engage in farming. Leaving the question of what would motivate someone to engage in small-scale farming. Motivation can be viewed through multiple lenses; this study chose to use self-determination theory to understand the motivations …

Government Program Decision Analysis In Nebraska At The Farm Level, Tatum R. Brunkow

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

The one-year extension of the 2018 Farm Bill until September 30, 2024, has extended several government programs for the 2024 crop year including those in Title I: Commodities. This analysis looks at three different financial scenarios and analyzes five different alternatives for a case farm to select the optimal farm program decision for the operation by evaluating net farm income. Since 2021, eligible producers have been able to elect either Agriculture Risk Coverage (ARC) or Price Loss Coverage (PLC) for their operation on an annual basis. Support levels for these programs are trending close together making the election decision more …

Impact Of Strategic Postweaning Supplementation On March- And May-Born Yearling Range Heifer And Calf Growth And Performance In The Nebraska Sandhills, Josie Nicole Crouch

Department of Animal Science: Dissertations, Theses, and Student Research

Three experiments were conducted at the Gudmundsen Sandhills laboratory near Whitman, Nebraska. Experiment 1, a retrospective regression analysis, evaluated the impact of heifer percentage of mature body weight (BW) at breeding on heifer performance, subsequent pregnancy rates, and calf production. Overall pregnancy rates were greater (P < 0.01) for heifers at 60 to 70% of mature BW than 50 to 55%, with no differences in pregnancy rates (P ≥ 0.15) after 2-years of age. Heifers at 50 to 60% of mature BW had a greater (P = 0.05) proportion give birth in the first 21-d. A higher percentage of mature BW at breeding resulted in greater (P < 0.01) BW at birth and weaning for offspring.

Experiments 2 and 3 were 3-year studies that evaluated the impact …

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 …

2022 Census Of Agriculture: Nebraska Highlights, Kathleen Brooks, Bradley D. Lubben

Cornhusker Economics

In February 2024, the United States Department of Agriculture National Agricultural Statistics Service published data from the 2022 Census of Agriculture. This data is collected every five years. The current article highlights a few of the Nebraska numbers. Two significant highlights from the data are the total number of farms and the total value of production. U.S. farm numbers declined modestly in the U.S. from 2.04 million in 2017 to 1.90 million in 2022. The total value of production for U.S. farms and ranches increased substantially from $388.5 billion in 2017 to $543.1 billion in 2022. Crop production accounted for …

Embracing Diversity In Agricultural Economics, Timothy Meyer

Cornhusker Economics

To steal an overused cliché, “There’s room in the tent for everyone.” Over the 2023 academic year, I have reiterated this message to all my students, with one addition. Not only is there room for everyone, but all are invited AND welcome. Food is something we all have in common, no matter the background. I think this is why producers in the state of Nebraska feel as strongly as they do about the food they produce; it is life-giving and should be taken seriously. Nebraska Agriculture is part of what makes our state great, and that is not a secret …

Nebraska Cooperative Extension: Faculty and Staff Publications

On-farm research has emerged in recent years as a unique approach to involve farmers and other agricultural stakeholders as active participants in knowledge development and as an effective method of technology and innovation transfer across farms. This study assessed the perspective and knowledge of US farmers regarding on-farm research via the implementation of a 24-question survey distributed across most of the US Midwest and South-Central regions.We found that farmers generally are willing to engage with universities to conduct on-farm research and were 40% more likely to adopt practices supported by on-farm research findings than research not conducted on-farm. Notably, a …

Are Too Many Or Too Few Babies Being Born?, E. Wesley F. Peterson

Cornhusker Economics

An additional 1.8 billion people will be added to the world’s population by 2050. At the same time, average incomes are likely to rise. Data from the Groningen Growth and Development Center suggest that average real (inflation-adjusted) GDP per capita increased by a factor of fifteen between 1820 and 2018 and World Bank data indicate that real per capita GDP more than tripled over the past 62 years. It is likely that these trends will continue and there will be more people with higher average incomes in the future straining global food systems and natural resources. Slower population growth rates …

In addition to their value as cereal grains, wheat (Triticum aestivum L.) and triticale (× Triticosecale Wittmack) are important cool-season annual forages and cover crops. Yearling steer (Bos taurus) performance was compared in the spring following autumn establishment as for age cover crops after soybean [Glycine max (L.) Merr.] grain harvest. Replicated pastures (0.4 ha) were no-till seeded in three consecutive years into soybean stubble in autumn, fertilized, and grazed the following spring near Ithaca, Nebraska, USA. Each pasture (n = 3) was continuously stocked in spring with four yearling steers (380 ± 38 kg) for …

Measuring Changes In Pork Demand, Welfare Effects, And The Role Of Information Sources In The Event Of An African Swine Fever Outbreak In The United States, Pratyoosh Kashyap, Jordan F. Suter, Sophie C. Mckee

United States Department of Agriculture Wildlife Services: Staff Publications

African swine fever (ASF) has never been detected in the United States, but the current global outbreak threatens to change that. Although ASF poses no known risk to human health and is not a food safety concern, little is known about the response in U.S. consumer demand in case of an outbreak. We use an online survey experiment, following the one-and-one-half-bound dichotomous choice contingent valuation approach to estimate changes in consumers’ willingness to pay for pork in case of an ASF outbreak. Using these estimates, we find that demand for unprocessed pork (processed pork) products in the U.S. is predicted …

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 …

Perceptions Of The Farm Bill Among Nonmetropolitan Nebraskans, Rebecca J. Vogt, Heather Akin, Cheryl A. Burkhart-Kriesel, Bradley D. Lubben, L. J. Mcelravy, Timothy Meyer, Steven A. Schulz

Nebraska Rural Poll

The federal legislation known as the farm bill encompasses all things related to agriculture and food. This includes not only farm income safety net and conservation programs that typically come to mind when thinking about the farm bill, but also domestic food assistance programs (like SNAP), rural development (providing funding for items like broadband service, utilities, and housing programs) as well as programs that are focused on specific producers and crops. Given the variety of programs it entails, how familiar are rural Nebraskans with the farm bill and federal agricultural policy? Do rural Nebraskans support federal spending on the various …

Agriculture And Community Well-Being: A Review Of Three Research Studies, Marilyn R. Schlake

Cornhusker Economics

Personal observations are often obscure to the facts. For instance, recently I worked at a booth at Husker Harvest Days. The booth focused on rural community development. My observations were that many of the agricultural producers decided to not stop at our booth or for those who did stop, conversations showed a disconnect of the importance of their local community to their farm operations. Similarly, when working with communities, I have observed the lack of understanding of the importance of the agricultural producers to the local community’s well-being. Why the disconnect between these two very important components of our rural …

Perceptions Of Childcare In Nonmetropolitan Nebraska, Rebecca J. Vogt, Heather Akin, Cheryl A. Burkhart-Kriesel, Bradley D. Lubben, L. J. Mcelravy, Timothy Meyer, Steven A. Schulz

Nebraska Rural Poll

Lack of childcare is an issue in many rural Nebraska communities. According to a report from Voices for Children, most counties in the state (91%) do not have enough available licensed childcare slots to meet the current demand there. Furthermore, 11 counties in the state have no licensed childcare facilities. Many communities are exploring options of how to address these shortages to maintain their current residents or to be able to attract new residents. Given these challenges, what types of childcare are rural Nebraskans currently using? How far do they drive to get to their childcare? And how do rural …

Two Essays In Agriculture Trade And Food Security: 1. Decomposing The Impact Of Gmo Regulation On Bilateral Trade: An Application To Corn Trade; 2. Can Food-Security Policies In Tunisia Be Better Targeted?, Mohamed Amine Hedoui

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

This dissertation is composed of two essays on agricultural trade and food security. The first chapter is entitled “Decomposing the GMO regulation impact on bilateral trade.” The essay analyses the complex impact of GMO regulations among countries on bilateral trade with a focus on GMO approvals. Three effects impact bilateral trade flows between trade partners: productivity enhancements in the source country, sorting cost from bilateral dissimilarity in regulations, and stringency impact on import demand. We estimate the model using a panel dataset of corn trade and two econometric approaches (PPML, Heckman sample-selection). We find that GMO laxity in production of …

Insurance, Policy, And Education For Livestock Producers, Milan Chauhan, Bradley D. Lubben

Cornhusker Economics

Federal crop insurance programs have existed since the 1930s, but for livestock producers, federal insurance programs were virtually nonexistent until the past 20 years. Livestock producers may not face exactly the same production risks that crop producers face, but they do face similar production risks related to grazing capacity and forage production and of course face price risks just like crop producers do.

Community Well-Being And Civil Discourse In Nonmetropolitan Nebraska, Rebecca J. Vogt, Heather Akin, Cheryl A. Burkhart-Kriesel, Bradley D. Lubben, L. J. Mcelravy, Timothy Meyer, Steven A. Schulz

Nebraska Rural Poll

Rural Nebraskans are more positive about the current change in their communities this year but are less positive about its future. Starting two years ago, the proportion believing their community changed for the worse was more than the proportion believing it had changed for the better (similar to what occurred in 2003 and 2009). However, this year that trend reversed back to the typical pattern. This year, more believe their community has changed for the better than has changed for the worse. When asked about what they expect ten years from now, this year more people believe their community will …
