The Ethically Conscious Flower Consumer: Understanding Fair Trade Cut Flower Purchase Behavior In Germany, Meike Rombach, David L. Dean, Nicole Olynk Widmar, Vera Bitsch

Department of Agricultural Economics Faculty Publications

Fair trade flowers are an important niche product relevant to ethically conscious consumers. The study proposes a model that investigates key factors affecting the behavior of these cut flower consumers in Germany. The study serves to complement the existing studies dedicated to preferences for flower attributes and products, as well as consumers’ willingness to pay. It builds on an online survey with a representative sample of 772 German cut-flower consumers. Partial least squares structural equation modelling shows that concern for the treatment of workers from countries with poor environmental and labor reputations, the breadth of fair trade cut flower information …

2021 Cantaloupe Variety Evaluation In Indiana, Wenjing Guan, Dan Egel, Dennis Nowaskie, Dean Haseman

Midwest Vegetable Trial Reports

Indiana ranks sixth in cantaloupe production in the US. A total of 1,800 acres of cantaloupes were planted in Indiana with a production value of $8.6 million in 2018 (USDA 2021). Melon produced in Indiana is primarily eastern-type cantaloupes. Traditional eastern-type cantaloupes have less pronounced netting, larger fruit size, softer flesh and shorter shelf life compared with western-type cantaloupes. They are harvested at quarter-slip to full-slip stage, and require frequent harvest. Recently, extended shelf life varieties have been developed and are becoming attractive in the eastern market. This variety trial included 11 traditional eastern-type cantaloupes, as well as extended shelf-life …

Determining The Accuracy Of Holstein Bull Semen Prices With A Two-Tier Efficiency Model, Loren W. Tauer Oct 2021

Determining The Accuracy Of Holstein Bull Semen Prices With A Two-Tier Efficiency Model, Loren W. Tauer

Journal of Applied Farm Economics

The pricing accuracy of dairy bull semen available for artificial insemination is investigated using a price model cast in terms of a two-tier efficiency model, which allows estimating an overprice and underprice given the net return the bull’s daughter is expected to contribute to the farm based upon the transmittable trait characteristics of a bull. The estimation produces statistically significant coefficients, including the coefficients for the overpricing and underpricing of the semen. The average estimate of overpricing is around 25%, and the average estimate of underpricing is around 33%. As expected, low semen prices tend to be underpriced and high …


“Oh, You Shouldn’T Have!” Understanding Key Factors Impacting Cut Flowers Gifting Preferences In Germany, Meike Rombach, David L. Dean, Nicole Olynk Widmar, Vera Bitsch Oct 2021

“Oh, You Shouldn’T Have!” Understanding Key Factors Impacting Cut Flowers Gifting Preferences In Germany, Meike Rombach, David L. Dean, Nicole Olynk Widmar, Vera Bitsch

Department of Agricultural Economics Faculty Publications

Cut flower gifting preferences are relatively unexplored in Germany. This study proposes a model that investigates the impact of attitudinal, experiential, and socio-demographic factors on the cut flower gifting preferences of German consumers. For this purpose, an online survey with a representative sample of 978 German residents was conducted. Partial least squares structural equation modelling shows that active and passive engagement with plants and nature positively impact cut flower giving preferences through cut flower knowledge, cut flower fondness, and perceived versatility of cut flowers. For German women and men, the largest driver of cut flower giving preferences is the versatility …

Does The Covid-19 Pandemic Change Consumers’ Food Consumption And Willingness-To-Pay? The Case Of China, Wei Yue, Na Liu, Qiujie Zheng, H Holly Wang

Department of Agricultural Economics Faculty Publications

Since COVID-19 was first detected in China in 2019, governments around the world have imposed strict measures to curb the spread of the coronavirus, which substantially impacted people’s life. Consumers’ food consumption behavior has also changed accordingly with reduced grocery shopping frequency, replaced in-person grocery shopping with online shopping, and increased valuation on food. In this paper, we aim to investigate the change in Chinese consumers’ food consumption and their willingness to pay (WTP) for vegetables and meat, using a dataset with 1206 online samples collected between February and March 2020. Consumers’ WTP for vegetables and meat is estimated using …

Department of Earth, Atmospheric, and Planetary Sciences Faculty Publications

Climate change and variability is affecting maize (Zea mays L.) production in eastern Ethiopia but how farmers perceive the challenge and respond to it is not well documented. A study was conducted to analyze smallholder maize farmers’ perception of climate change/variability and identify their adaptation approaches and barriers for adaptation in the eastern highlands of Ethiopia. Meteorological data were assessed to provide evidence of the perceived change. A survey was conducted in six major maize-producing kebeles with a total of 364 respondents. A multi-stage sampling method was employed for selecting the sample units for the study. The data were analyzed …


Commitment Behaviour In The World Trade Organization's Trade Facilitation Agreement, Russell Hillberry Jul 2021

Commitment Behaviour In The World Trade Organization's Trade Facilitation Agreement, Russell Hillberry

Department of Agricultural Economics Faculty Publications

We use a new database of commitments made during the process of ratifying the Trade Facilitation Agreement (TFA) to study variation in countries’ commitment behaviour. The TFA is a novel World Trade Organization agreement because it allows developing countries to select commitments from a menu of best practices in trade facilitation, rather than to consent, or not, to a comprehensive package of negotiated commitments. The operation of this á la carte approach to concluding trade agreements is worthy of study in its own right, but the commitment data also offer a high-level description of progress in an international effort to …

Hemp Production Network Effects: Are Producers Tipped Toward Suboptimal Varietal Selection By Their Neighbors?, Tanner Mccarty, Jeffrey Young Feb 2021

Hemp Production Network Effects: Are Producers Tipped Toward Suboptimal Varietal Selection By Their Neighbors?, Tanner Mccarty, Jeffrey Young

Journal of Applied Farm Economics

The 2018 farm bill removed industrial hemp from the Schedule 1 Controlled Substance List. In response, states scrambled to enact hemp legislation. Some hemp flower producers report their hemp fields were cross- pollinated by a neighbor growing a different hemp cultivar. For hemp flower crops, cross- pollination reduces cannabinoid concentration levels within the flower; these concentration levels dictate flower price. We show that in a repeated game, once a sufficiently large percentage of growers decide to plant hemp fiber/seed crops, cross-pollination forces flower growers to convert to fiber/seed to avoid the negative network externality. Over time, a stable, suboptimal Nash …


Evaluation Of Bell Pepper Cultivars With And Without Resistance To Bacterial Leaf Spot And Phytophthora, West Central Minnesota, Nathan Dalman, Steve Poppe Jan 2021

Evaluation Of Bell Pepper Cultivars With And Without Resistance To Bacterial Leaf Spot And Phytophthora, West Central Minnesota, Nathan Dalman, Steve Poppe

Midwest Vegetable Trial Reports

Bacterial leaf spot (BLS) and Phytophthora (PHY) diseases are a common problem for Minnesota bell pepper producers and if not detected and treated early enough, these diseases can kill the plants. There are cultivars that have resistance to these particular diseases but these cultivars must maintain yields similar to traditional cultivars in order to be desired by producers and buyers. Our goal was to determine any differences in performance between cultivars with and without resistance. Yield, fruit size and number of fruit per plant were the evaluated characteristics.

Chile Pepper Variety Evaluation At Four Sites Across Minnesota And Wisconsin, 2020, Charlie Rohwer, Natalie Hoidal, Cala Farm, Agua Gorda Farm Cooperative, Jarl's Produce

Midwest Vegetable Trial Reports

Latinx fresh market vegetable farmers in Minnesota face numerous barriers to market access. Many Latinx farmers live in rural communities where farmers market sales are low, and opportunities for wholesale are limited. The growers who make up Shared Ground Farmers’ Cooperative have developed an innovative cooperative marketing system to aggregate produce and sell it in Twin Cities markets, but many of the individual farmers involved also wish to find ways to keep the produce they grow in their own communities. This project emerged through a series of discussions about finding niche markets for culturally relevant crops in small-town Mexican restaurants …

Effects Of Using Low Tunnel And Grafted Plants For Watermelon Production Under Low Temperature Stress In Indiana, Wenjing Guan Jan 2021

Effects Of Using Low Tunnel And Grafted Plants For Watermelon Production Under Low Temperature Stress In Indiana, Wenjing Guan

Midwest Vegetable Trial Reports

This study evaluated the effect of using low tunnel and grafted plants for early-season watermelon production in Indiana. Results of the study indicated that grafted seedless watermelon plants can better tolerate cold stress in the early watermelon season compared to non-grafted seedless watermelon plants. Grafted plants with ‘Camelforce’ rootstock had better old tolerance than that of ‘Carolina Strong Back’ rootstock. The effect of using low tunnels to improve plant survival rate under extreme weather conditions is limited, which depend on temperate stress and cold tolerance of the plants.

Creating Awareness Of The Turkey Industry Through Stem-Based Online Curriculum, Elizabeth Simmermeyer, Elizabeth Karcher

Indiana STEM Education Conference

As the food industry has evolved over the years, consumers have more accessible and convenient outlets to buy groceries, dine in, or carry out. While there are many advantages to this ever-changing industry, a large gap exists in the understanding of food production from farm to fork. Consumer perceptions are influenced beginning at an early age. Education is the solution to bridge this gap between farm to fork; however, there are limited STEM-based agricultural resources available for teachers to implement in their classrooms. Creating these agricultural resources provides teachers the opportunity to share the story of the agricultural industry with …


Harvest Of The Month, Abigail E. Heidenreich Jan 2021

Harvest Of The Month, Abigail E. Heidenreich

Indiana STEM Education Conference

Harvest of the Month curriculum exists in many states, but Indiana lacks a statewide effort in this area. To meet this need, collection of lessons with complementary activities that are specific to Indiana agriculture were created. The driving force behind the curriculum was to create a lesson that is fun and engaging for students, but also well-rounded and standards-based for teachers. Components of the lesson include Life Cycle Discussions, Taste Testing, Interactive Activities, and Journal Prompts. Partnering with Indiana farmers, a harvest video was created to accompany each lesson that features a different agricultural product grown in Indiana each month. …

Intersectionality Shapes Adaptation To Social-Ecological Change, Anna Erwin, Zhao Ma, Ruxandra Popovici, Emma Patricia Salas O'Brien, Jonathan Bauchet, Nelly Ramirez Calderón, Glenn Roberto Arce Larrea

Department of Agricultural Economics Faculty Publications

People from across the Caylloma Province of Peru are adapting to social-ecological changes, such as decreasing water supplies and rapidly retreating glaciers, in different and unequal ways. In this study, we show how this inequality is intersectional; identities like gender and age compound and interact with systems of power to shape how people adapt to these changes at the individual, household, and district scales. We draw from 130 semi-structured interviews with agricultural actors and participant observations in district and regional meetings across four districts, to demonstrate how intersectionality shapes adaptation to social-ecological change. Our results show (1) what social-ecological changes …

#Eggs: Social And Online Media-Derived Perceptions Of Egg-Laying Hen Housing, Nicole Olynk Widmar, Courtney Bir, Christopher Wolf, John Lai, Yangxuan Liu

Department of Agricultural Economics Faculty Publications

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 …


Presenting Smaller ‘Component Designs’ In Place Of Large Discrete Choice Experiment, Courtney Bir, Michael S. Delgado, Nicole Olynk Widmar Oct 2020

Presenting Smaller ‘Component Designs’ In Place Of Large Discrete Choice Experiment, Courtney Bir, Michael S. Delgado, Nicole Olynk Widmar

Department of Agricultural Economics Faculty Publications

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.
