ESSAYS ON CATTLE-DERIVED FOOD PRODUCTS: DEMAND, PRICING, AND INVESTIGATION INTO LINKAGES BETWEEN ONLINE MEDIA AND FUTURE PRICES

Mario Amado Ortez Amador (13150497) 25 July 2022 (has links)
<p>  </p> <p>Cattle derived food, like beef and dairy, have long been a staple of our human diets and continue to be prominent in our days. This prominence and their relevance naturally extend to our economies. According to the U.S. Department of Agriculture, Economic Research Service (2022), cattle production is the most important agricultural industry in the US representing about 17% of the $391 billion total cash receipts for agricultural commodities in 2021.</p> <p><br></p> <p>Economists have looked into cattle derived products from a wide array of perspectives focusing on the product itself, for example beef, but also in the forces of supply and demand that at times are external to product attributes. The effect of supply and demand shocks on agricultural markets have been heavily considered in the literature (Thomsen and McKenzie, 2001; McKenzie and Thomsen, 2001; Lusk and Schroeder, 2002, Piggott and Marsh, 2004). Yet another important aspect of agricultural markets is price determination and the body of literature in this area is ample (Tomek & Robinson, 2003). Recent phenomena in the world, like the availability of information, good or bad, in the most current, voluminous and accessible way that we have ever seen, could be a new force in price determination of agricultural products. My research contributes to such strains of literature by investigating perceptions and willingness to pay for beef attributes, market shocks in beef markets, and the role of online media in dairy prices.</p> <p><br></p> <p>Beef attributes, and their relative valuation by consumers, have been studied to assist in understanding consumer demand for beef. Given the relevance of such attributes in consumer’s mind, researchers have sought to study how to profitably provide those beef attributes demanded by consumers. Addressing consumer demands for tenderness, an important attribute (Schroeder and Mark, 2000), aging beef has been proved to be a technology that improves flavor, tenderness and juiciness (Kim, Kemp & Samuelson, 2016). By using aging processes, the same cattle carcass can generate more highly valued beef products. I study the willingness to pay for aging and USDA grade in beef, to understand valuation of attributes by consumers with various demographics. </p> <p><br></p> <p>In beef markets, the heterogeneity of beef cuts in their usage, pricing and distribution channels is crucial. Supply and demand shocks can affect individual cuts in different ways (Ortez et al, 2022). With some beef cuts relying heavily on restaurant sales more than others, this offers a good opportunity to introduce a new concept in beef market analysis, namely the price relationship amongst beef cuts and its response to different market shocks. The traditional discussion around spreads in meat focus on differences in price at separate steps in the supply chain, namely farm, wholesale and retail. However, little attention has been given to the relative differences in prices of specific cuts of beef.</p> <p><br></p> <p>The potential influence of online media chatter in its sentiment and volume has largely been under appreciated in the Agricultural Economics literature. A predecessor in this area is Tonsor and Olynk (2011) who first established a connection between news activity and economic fundamentals in agriculture. The advent of the internet may have the ability to decrease information asymmetry and bridge the information gap between consumers, producers and market products. Online media listening allows for data collection efficiently and in real time (Widmar, 2019) and it may be a relevant aspect in the decision making of agricultural and food industries. Moved by this endeavor, I seek to understand if potential relationships between online media chatter sentiment and volume with futures prices in dairy products exist.</p> <p>  </p>

Japanese University Students’ L2 Communication Frequency in Positive Classroom Climate

Shimizu, Sunao January 2017 (has links)
The primary purpose of study is to identify predictors of willingness to communicate (WTC) and of actual frequency of English communication at work inside and outside the foreign language classroom among 439 university students (male = 226, female = 213) learning English in Japan. Based on Wen and Clément’s (2003) theory of L2 WTC, I replicated Peng and Woodrow’s (2010) structural path model using the variables of state L2 communicative confidence, L2 learning motivation, positive classroom climate, L2 WTC, with the newly added variable of actual speaking frequency. A hypothesized structural model was examined in two contexts, WTC inside the classroom and WTC outside the classroom. Inside the classroom, communicative confidence was the predictor of L2 WTC. L2 WTC and L2 learning motivation were predictors of actual frequency of L2 communication. Positive classroom climate was a mediating variable that indirectly predicted L2 WTC through state L2 communicative confidence and task motivation. In contrast, outside the classroom, state L2 communicative confidence, L2 learning motivation, and positive classroom climate were the predictors of L2 WTC. State L2 communicative confidence, task motivation, and positive classroom climate were the predictors of actual frequency of L2 communication. The results supported Wen and Clément’s (2003) model and Peng and Woodrow’s (2010) study. Second, Dӧrnyei and Kormos’ (2000) study was replicated to investigate a significant difference for the four types of the students’ speaking behavior between pretest and posttest. A repeated-measures ANOVA was performed for English turns, Japanese turns, English words, and interjections with 13 students (male = 8 and female = 5) aged 18-19. The 13 participants were part of those who completed the first questionnaire. There were no significant differences for the four dependent variables. Finally, a qualitative content analysis was performed using transcribed interview data with nine university students (6 male and 3 female students), who completed the first questionnaire. Ten variables emerged from the interviews. Four variables—teacher support, group cohesiveness, L2 learning motivation, and perceived communicative competence—supported both quantitative (Peng & Woodrow, 2010) and qualitative studies (Cao, 2011; Peng, 2007, 2012). Four additional variables—security of speaking, interlocutors, small group, and topic familiarity—supported qualitative studies by Cao (2011) and Kang (2005). The other two variables—point system and tests—were new variables identified in this study. Positive classroom climate and task motivation (Dӧrnyei & Kormos, 2000) were key variables influencing state L2 communicative confidence, L2 WTC, and L2 Use. As a result, I propose that task motivation and positive classroom climate should be added into MacIntyre et al.’s (1998) L2 WTC model. / Teaching & Learning

A Structural Equation Model and Intervention Study of Individual Differences, Willingness to Communicate, and L2 Use in an EFL Classroom

Munezane, Yoko January 2014 (has links)
In this study I investigated foreign language learners' Willingness to Communicate, frequency of L2 communication, and eight individual difference variables hypothesized to influence them: L2 learning anxiety, L2 learning motivation, integrativeness, international posture, ought-to L2 self, ideal L2 self, L2 linguistic self-confidence, and valuing of global English. Based on the concept of possible selves (Markus & Nurius, 1986), Dörnyei (2005) proposed the concept of the ideal L2 self: an idealized self-image involving future linguistic proficiency and professional success through mastery of an L2. In this study, Dörnyei's (2005) hypothesis that Willingness to Communicate is primarily determined by linguistic self-confidence and the ideal L2 self is tested using a structural equation model. A second purpose of this study, tested by comparing alternative structural equation models, was to confirm whether students' self-reported Willingness to Communicate best predicts foreign language use in the classroom. In addition, gender differences in L2 WTC and the ideal L2 self, and the effects of visualization and goal-setting activities on the enhancement of Willingness to Communicate were investigated using multivariate statistical techniques. A total of 662 Japanese university students participated in the study, 373 as core participants and 289 for cross validation. A model was hypothesized based on the WTC model (MacIntyre, 1994), the socioeducational model (Gardner, 1985), and the concept of the L2 Motivational Self System (Dörnyei, 2005), and tested using questionnaire data collected at the beginning of the university semester. The hypothesized model showed marginal fit to the data (CFI = .902, RMSEA = .081). The path from ideal L2 self to L2 WTC, tested for the first time in this study, was the most substantial predictor of L2 WTC in the model with a path weight of .51. It was also confirmed that self-reported estimates of WTC directly predicted observed L2 use in the classroom, while Motivation and Ideal L2 Self did not. A model specifying a direct path from WTC to L2 Use and indirect paths via WTC for Motivation and Ideal L2 Self showed good fit to the data (CFI = .962; RMSEA = .083). Regarding gender differences, female participants scored higher than males in both L2 WTC and Ideal L2 Self. Concerning whether L2 WTC can be enhanced by classroom tasks such as visualization and goal-setting, the results suggested that the visualization treatment alone was not effective in enhancing learners' L2 WTC over the non-treatment group. The increase in learners' L2 WTC was significantly greater for the When visualization and goal-setting group compared with the visualization group and the non-treatment group. The first implication of this study is that considering the strong impact of ideal L2 self on L2 WTC, there is significant potential for enhancing L2 WTC by applying motivational strategies that enhance or develop second language learners' ideal L2 self. Second, considering the importance of L2 output for developing communicative proficiency, the finding that self-reported L2 WTC predicted actual L2 use in the classroom lends additional credence to such motivational approaches. That finding also supports the validity of other studies that have relied on self-report for measures of L2 WTC. A third implication is that because females generally exhibited higher measures for L2 WTC and Ideal L2 Self, gender diversity is preferable to promote active classroom communication. Finally, for researchers and practitioners interested in designing activities to enhance learners' L2 WTC, connecting the proximal goals in the class to future distal goals (Miller & Brickman, 2004) could be an important aspect for the success of the activities). / Teaching & Learning

A MODEL OF SITUATIONAL CONSTRUCTS ACCOUNTING FOR WILLINGNESS TO COMMUNICATE AT A JAPANESE UNIVERSITY

Robson, Graham George January 2015 (has links)
Many researchers have highlighted the need for students to have a willingness to communicate (WTC) in second and foreign language classrooms. WTC is important because it is believed that WTC leads to eventual communication both inside and outside the classroom. Previous research into WTC has centered mainly on the use of structural models and trait, self-reported measurements of WTC, but recent research has shown that WTC is also heavily dependent on the situation. However, very few studies recognize this and have, thus, not employed situational measurements of WTC. After a thorough review of WTC literature, 13 pertinent constructs were modified to reflect the situation in the foreign language classroom. These were related to constructs of the classroom, beliefs about communication; self-determined motivation; self-perceived competence; communication anxiety and willingness to communicate. A preliminary study employing exploratory factor analysis and Rasch analysis, followed by a main study conducted with and confirmatory factor analysis and Rasch analysis were undertaken with first- and second-year Japanese university students. The factor analysis was used to investigate the underlying structures of the factors and the Rasch analysis was used to determine fit, category functioning and dimensionality. Nine reliable and unidimensional factors were brought forward from the main study, which were Classroom Efficacy Factor and Classroom Affective Factor as the two classroom factors; Intrinsic Motivation for Communication, Introjected Regulation for Communication and External Regulation for Communication as the three self-determined motivation constructs, and finally, Self-Perceived Competence, Communicative Anxiety and Willingness to Communicate split in two subconstructs of pair/work and whole class activities. The second half the study was the formulation of a structural equation model using the above constructs to predict situational WTC. The model also included an often under-utilized resource, the teacher, who assessed the learners’ actual communication to identify if WTC leads to language use. All the fit indices in the final model (N = 376) were good, and the model included three additional paths. The model indicated that classroom constructs led to motivation and self-perceived competence, which predicted confidence. Motivation led directly to WTC and indirectly to WTC through confidence. Lastly, WTC predicted actual communication. The constructs in this study can be applied in other studies of situational WTC. This study helps to both expand our understanding of constructs affecting situational WTC and actual communication, and provides more validity to the construct of situational WTC. It also reaffirms the importance of what happens in the classroom, which is main arena for communication in the EFL setting. / Language Arts

How far are you willing to go when the prices are so low? : A mixed-method study on how ultra-fast ecommerce marketing strategies affect consumers sustainability beliefs.

Holma, Matilda, Junestrand, Alva January 2024 (has links)
The surge in online shopping, catalyzed by the COVID-19 pandemic, has reshaped consumerbehavior worldwide. Ecommerce platforms account for a substantial portion of retailtransactions, and as the digital marketplace continues to expand, the allure of ultra-fastecommerce platforms such as Shein, Temu, and AliExpress grows exponentially. Theseplatforms offer an extensive array of products at unprecedented response to immediate trendsand affordability, leveraging aggressive marketing strategies to capture consumer attention.However, the convergence of ultra-fast ecommerce raises concerns about environmentaldegradation, unethical production practices, and labor exploitation. Brands operating withinthis business practice often prioritize profit margins over sustainability, perpetuating a throw-away culture that undermines efforts towards ethical consumption. The environmental andsocial implications of this rapid consumption trend remain underexplored, and what this mixed-method study aims to investigate is the intricate relationship between ultra-fast ecommercemarketing tactics and consumer sustainability beliefs, focusing on Swedish consumers. Afterextensive literature review and empirical research involving a survey of 122 consumers and 6follow-up interviews, this study examines the multifaceted influences of ultra-fast ecommercemarketing on Swedish consumers' shopping behaviors and sustainability attitudes. Ourinvestigation focuses on the complex interplay between price consciousness, impulsiveness,trend seeking and opinion seeking behavior, and the persuasive power of marketing tacticsemployed by ultra-fast ecommerce platforms. Our findings suggest that while Swedishconsumers express a strong commitment to sustainability in principle, the attraction of lowprices often eclipses environmental and social considerations when making purchasingdecisions on ultra-fast ecommerce platforms. Marketing strategies such as paid advertising,influencers, UGC, and aggressive discounts play a pivotal role in driving opinion seeking,impulsive and compulsive buying behaviors among consumers. Empirical findings reveal a lackof consumer awareness regarding the environmental and ethical consequences of ultra-fastecommerce purchases, and skepticism toward sustainability claims made by low-pricecompanies. However, consumers demonstrate high trust in influencers, who play a significantrole in shaping purchasing decisions, particularly regarding ultra-fast ecommerce. By shedding light on how ultra-fast ecommerce marketing strategies affect consumer behavior,this research contributes to academic scholarship and offers a range of practical implications.We offer a deeper insight into how consumers make choices and suggest ways to encouragepro-sustainable shopping habits in the ecommerce marketplace. Ultimately, this studyunderscores the urgent need for more studies focusing on regulatory frameworks, industrystandards, consumer education initiatives together with tailored marketing strategies that alignwith consumer values and how to promote ethical consumption practices to reduce the negativeimpact of ultra-fast ecommerce on the environment and on ethical aspects. By empoweringconsumers with knowledge and promoting ethical alternatives, we can encourage moreconscious and responsible purchasing decisions, ultimately contributing to a more sustainableand equitable digital marketplace.

Opportunity Between the Turbines: A Willingness-to-Pay Experiment Regarding Co-Location Activities with the Coastal Virginia Offshore Wind Farm

Fluharty, Shannon Mae 13 September 2021 (has links)
With shipping routes, fisheries, conservation areas, recreation, and other maritime industries competing for space off Virginia's coastline, integrated solutions for marine areas may offer a way to limit conflict and maximize productivity. Countries across the world are researching the different ways in which the space between turbines can be utilized to provide economic and environmental benefits. The act of coupling other maritime activities with offshore wind farms is often referred to as co-location. As Virginia constructs the first offshore wind farm in United States Federal waters, there are new opportunities for co-location that could benefit the Virginia economy. Using data from a choice experiment and random utility modeling, this research quantifies Virginia public preferences for various co-location options within the lease area of the Coastal Virginia Offshore Wind (CVOW) farm. Our estimated WTP values show Virginia's public preference for the addition of co-location to the CVOW lease area to be upwards of $20 per 1,000 acres of activity. Our estimates can be compared to implementation and management costs of each activity to determine potential for incorporation of certain co-location techniques. The experimental design of this study can be applied to other offshore wind installments around the world. / Master of Science / With shipping routes, fisheries, conservation areas, recreation, and other maritime industries competing for space off Virginia's coastline, integrated solutions for marine areas may offer a way to limit conflict and maximize productivity.

Investigating specialty crop farmers’ preferences for contract design and attitudes towards blockchain-based smart contracts

Agyemang-Duah, Esther Mmenaa 08 August 2023 (has links) (PDF)
This study examines small and medium scale specialty crop growers’ preferences for marketing contract attributes and willingness to adopt blockchain-based smart contracts. The data used were collected using an online survey and discrete choice experiment. Findings indicate that farmers prefer higher average prices, cash, check or electronic bank payment over cryptocurrency, and immediate payment upon product delivery over delayed payment. When choosing a contract, farmers viewed traditional text-based contracts and digital platforms with automated smart contracts equivalently, on average. On average, farmers showed no preference for providing and not providing traceability lot codes to buyers, and between choosing a contract and marketing their products as usual. Although we find that some farmers prefer to provide traceability lot codes to buyers while others do not, and some farmers prefer having a contract option while others do not. These insights could be useful to buyers and specialty crop farmers seeking to contract.

WTP for RAS salmon by the US consumer

Wu, Isaac Ying-Nan 16 May 2024 (has links)
Marine omega-3s, EPA and DHA, have been strongly evidenced to decrease the risk of cardiovascular disease, the leading cause of death in the United States. One of the richest sources of EPA and DHA in the U.S. diet is farmed Atlantic salmon, which has shown a steady consumption growth in the past decade. The U.S. shows the most production potential for salmon produced with an emerging production method, recirculating aquaculture systems (RAS), which directly addresses the environmental challenges associated with the traditional farming method, open-net pens. Because of the higher costs associated with RAS, the salmon it produces requires a price premium, and little is known about whether U.S. consumers are willing to pay such a premium. We conduct a hypothetical choice experiment across all major regional markets of the U.S. (n = 2857) to estimate consumers' willingness-to-pay for RAS and other attributes valued by producers and consumers. Our results show that U.S. consumers are willing to pay a premium for RAS, but only after prioritizing freshness (fewer days since harvest) and U.S. production, all of which were significant to the p < .001 level. Higher omega-3 content also justified a significant premium, but byproduct recycling and stocking density did not have any real influence on purchases. We express these willingness-to-pay (WTP) estimates as percentages of a reference product priced with model estimates. These adjusted retail premiums should be paired with RAS salmon production costs to understand the economic viability of RAS and illuminate the path to EPA and DHA nutrient security in the U.S. / Master of Science / Two micronutrients found in cold-water fish, EPA and DHA, have been strongly evidenced to decrease the risk of cardiovascular disease, the leading cause of death in the United States.
