As margins are reducing for agricultural producers there is a concerted effort to analyze all costs. One such cost for rice producers in Arkansas is their contribution to the Rice Check-off Program. This study analyzes the cost-benefit ratio of funds contributed by Arkansas rice producers and the holistic (both economic and environmental) benefits they receive. This study analyzes just five of the many programs the Rice Check-off Program invests in through the University of Arkansas System Division of Agriculture (UASDA) and suggests that every dollar invested generated an average return of $28.49 between 2002–2018 ($70.45 when ecosystem benefits are included). …

The lack of a flood on rice (Oryza sativa) levees and in furrow-irrigated rice creates a favorable environment for terrestrial weeds like Palmer amaranth (Amaranthus palmeri S. Wats) to emerge and quickly overtake the crop for a longer portion of the year than in flooded rice culture. Florpyrauxifen-benzyl is a new auxin herbicide labeled for use in rice that has activity on both grasses and broadleaf weeds, as well as certain sedges. Field experiments were conducted to determine the efficacy of florpyrauxifen-benzyl in a non-flooded environment. Experiments were conducted in 2017 and 2018 at the Lon Mann …

Enormous quantities of data are generated through social and online media in the era of Web 2.0. Understanding consumer perceptions or demand efficiently and cost effectively remains a focus for economists, retailer/consumer sciences, and production industries. Most of the efforts to understand demand for food products rely on reports of past market performance along with survey data. Given the movement of content-generation online to lay users via social media, the potential to capture market-influencing shifts in sentiment exists in online data. This analysis presents a novel approach to studying consumer perceptions of production system attributes using eggs and laying hen …

Employing a sample of US residents, a new WTP (willingness-to-pay) data collection method using component discrete choice experiments is proposed and compared to the traditional method. The WTP experiments elicit consumer's WTP for potentially animal welfare improving production practices and product attributes in yogurt. The new data collection method was designed to decrease complexity by having respondents participate in fewer choice scenarios. Incidences of attribute non-attendance (ANA), a potential simplifying heuristic, occurred less frequently for all but one attribute in the new WTP data collection method. Exhibiting ANA for any attribute was negatively correlated with the time for completion.

The Economic Impacts Of Social Activism In Food Markets, Anubrata Deka, Emie Yiannaka, Konstantinos Giannakas
Cornhusker Economics
Private politics, usually led by nongovernmental organizations (NGOs) and social activists, focuses on changing the behavior of private economic agents through social pressure rather than through government action (although government action is also possible) (Baron, 2003). The food sector has been experiencing increased social pressure from social activist organizations to achieve diverse goals, ranging from improving food safety and food fortification to increasing transparency in food markets. A primary reason for the increase in organized activism in the food sector is the proliferation of the provision of credence attributes which are attributes unobservable through search or experience (consumption and use). …

Corruption And Cooperative Organizations, Konstantinos Giannakas, Murray E. Fulton
Cornhusker Economics
Although the literature is limited, there is evi-dence that corruption in cooperatives and inves-tor-owned firms (IOF) is widespread in develop-ing and transition economies where corruption generally is common. Cooperative corruption is also found closer to home. Two recent examples from the United States include the Ashby Farm-ers’ Cooperative Elevator in Minnesota where the general manager stole from the cooperative and the Tri-County Electric Cooperative in South Carolina where board members enriched them-selves with perks and benefits. In Canada, the PACE Credit Union was placed under the regula-tor’s control in 2018 after two senior executives were discovered to have received secret …

Dairy Product Purchasing In Households With And Without Children, Mario Ortez, Courtney Bir, Nicole Olynk Widmar, Jonathan Townsend
Department of Agricultural Economics Faculty Publications
Dairy products are considered a staple in the American diet due in part to their nutritious content and appealing flavor. Consumption patterns may differ among age segments influenced by preferences for fat content and taste in dairy. Furthermore, having children in their household may influence the amount, frequency, and type of dairy products that a consumer chooses to purchase. This study finds that households that frequently bought food for children generally purchased larger quantities of fluid milk and more fluid milk with a higher fat content. Households with children also bought yogurt more frequently than other households. Labeling information of …

Distillers Grains Pre, During, And Post Covid-19: Ongoing Recovery And Structural Demand Implications, Daniel Gertner, Elliott James Dennis
Cornhusker Economics
Prior to the shutdowns caused by the COVID-19 pandemic, distillers grains and other co-products of ethanol production played a crucial role in maintaining the rev-enue stream of dry mill ethanol plants (Irwin 2020). With low crude oil prices over the last half of the decade and corn prices holding steady over the same period of time, the margin for error in the ethanol industry was thin. More than a third of Nebraska’s ethanol plants either temporarily or permanently closed in 2019 (MacroTrends 2020); (York News Times 2019). To prevent similar outcomes, ethanol plants focused on diver-sifying their operations to produce …

Change In Level Water In Pumping-Plant Intake, R.R. Ergashev, B.T. Xolbutayev
Irrigation and Melioration
A decrease in the water level in the pump chamber of the pumping stations leads to the formation of whirlpools in front of the suction pipes. As a result of air intake, the pump unit operates in cavitation mode and their intensive wear occurs. As the data obtained from the Karshi machine channel show, mainly a decrease in design water levels in the downstream waters is observed at the first pumping station. Depending on the number of simultaneously operating pumping units, the minimum water level in the head pumping station should be from 4.5 m to 5.7 m. The received …

The Role Of Quality Characteristics In Pricing Hard Red Winter Wheat, Shane J. Roberts
The Role Of Quality Characteristics In Pricing Hard Red Winter Wheat, Shane J. Roberts
Department of Agricultural Economics: Dissertations, Theses, and Student Research
In this thesis, we empirically examine the role of conventional and end-use wheat quality characteristics on the pricing of hard red winter wheat (HRWW). We use detailed quality characteristic data as well as location matched price data for 50% and 100% harvest completion weeks and utilize a hedonic price analysis framework. We find evidence that end-use characteristics, specifically milling and baking quality characteristics, have a statistically and economically significant effect on the price of HRWW. This evidence suggests that, while HRWW producers are not directly paid premiums or discounts for end-use quality, they are paid indirectly through basis. Comparing results …

Preserving Cultural Heritage Through The Valorization Of Cordillera Heirloom Rice In The Philippines, Subir Bairagi, Marie Claire Custodio, Alvaro Durand-Morat, Matty Demont
Agricultural Economics and Agribusiness Faculty Publications and Presentations
For centuries, heirloom rice varieties have been grown on the terraces of the Cordillera Mountains of Luzon, Philippines, terroirs known for their significant historical, cultural, and aesthetic values. However, heritage heirloom rice farming is gradually being abandoned, mainly because of its lower productivity and the struggle of the sector to create a sustainable niche market for heirloom rice by branding its cultural, social, and nutritional values. We propose several demand-side intervention strategies for the valorization of heirloom rice. To support the development of a segmented marketing strategy for heritage farming, we provide evidence on urban consumers’ willingness to purchase heirloom …
