UNIVERSITY PARK, Pa., April 12, 2022 /PRNewswire-PRWeb/ -- The sentiments and emotions expressed in tweets on Twitter can be used in real time to assess where supply chain disruptions due to a pandemic, war or natural disaster may lead to food shortages, according to researchers at Penn State and the Hamad Bin Khalifa University in Qatar. They found that food security-related tweets that expressed anger, disgust or fear were strongly correlated with actual food insufficiency in certain U.S. states early in the COVID-19 pandemic. These findings can potentially be used to develop a low-cost early warning system for identifying where food-security interventions are most needed, according to the researchers.

Key Points: 
  • They found that food security-related tweets that expressed anger, disgust or fear were strongly correlated with actual food insufficiency in certain U.S. states early in the COVID-19 pandemic.
  • Goetz said that rather than looking only at the number of tweets related to food insufficiency, he and his colleagues wanted to know how people actually felt about their food situation.
  • Using artificial intelligence, they identified the sentiments and emotions associated with the tweets, which allowed them to separate tweets expressing concerns about the food supply from those expressing relief or contentment.
  • Tweets that expressed negative emotions such as anger, disgust and fear were strongly correlated with actual food insufficiency problems in certain states.

MILWAUKEE, April 4, 2022 /PRNewswire-PRWeb/ -- The war in the Ukraine underlines the importance of food production for food security. EU policy makers have to be aware about the implications of the farm-to-fork strategy for food security. According to the European Commission "The Farm-to-Fork Strategy is at the heart of the European Green Deal aiming to make food systems fair, healthy, and environmentally-friendly"

Key Points: 
  • EU policy makers have to be aware about the implications of the farm-to-fork strategy for food security.
  • Wesseler says, "The quantitative assessment of benefits and costs by previous studies indicates that the farm-to-fork strategy will reduce welfare within the EU.
  • ABOUT AAEA: Established in 1910, the Agricultural & Applied Economics Association (AAEA) is the leading professional association for agricultural and applied economists, with 2,500 members in more than 60 countries.

MILWAUKEE, Wis., March 29, 2022 /PRNewswire-PRWeb/ -- Global interest in commodity markets for plant-based protein is high for several reasons; associated interest in consumer sentiment and demand for protein items remains elevated. A 1% decline in Beyond Beef's offering price is projected to increase the probability of Beyond Beef being selected by 3.6% for regular meat consumers and 1.6% for those declaring an alternative diet such as Vegan, Vegetarian, or Flexitarian. This reflects regular meat consumers being more sensitive to price changes.

Key Points: 
  • MILWAUKEE, Wis., March 29, 2022 /PRNewswire-PRWeb/ -- Global interest in commodity markets for plant-based protein is high for several reasons; associated interest in consumer sentiment and demand for protein items remains elevated.
  • This reflects regular meat consumers being more sensitive to price changes.
  • In the new article " Market Potential of New Plant-based Protein Alternatives: Insights from Four U.S. Consumer Experiments ," Glynn Tonsor and Ted Schroeder from Kansas State University along with Jayson Lusk from Purdue University, assess the economic impact of plant-based protein offering being introduced in the United States.
  • Tonsor says, "We believe future economic research will be improved given availability of consumer demand elasticity estimates derived in this work.

MILWAUKEE, March 24, 2022 /PRNewswire-PRWeb/ -- With meat prices escalating during the Ukraine crisis and the possibility of a new COVID surge, more and more are turning to a plant-based meat to save a few dollars at the grocery store.

Key Points: 
  • In the new article " Do Plant-Based and Blend Meat Alternatives Taste Like Meat?
  • We find that beef burgers are preferred over the plant-based alternatives.
  • Overall, our results suggest that the success of plant-based alternatives is heavily dependent on the taste; as well as on the way these alternative burgers are made.
  • Recognizing taste as a key factor for the expansion of plant-based meat among meat-eaters, Beyond Meat, which used pea-like protein, has adjusted the composition of its burger to even more closely resemble a typical meat flavor."

Over 40% of agricultural undergraduate students were likely to be suffering from moderate to severe depression after the first wave of the COVID-19 pandemic.

Key Points: 
  • Over 40% of agricultural undergraduate students were likely to be suffering from moderate to severe depression after the first wave of the COVID-19 pandemic.
  • Ehmke says, "The study found there was a significant difference in agricultural students' mental health across genders in the first wave of the COVID-19 pandemic.
  • Women were much more likely, in general, to be at risk of depression and had lower life satisfaction than male students.
  • Yet, there are personal and environmental factors that helped to dampen the mental health adversity and increase the likelihood of students' resilience during the first wave.

In the new article " Mitigating Implicit Bias in Student Evaluations: A Randomized Intervention " published in the Applied Economics Perspectives and Policy, Joyce Chen, Brandon Genetin, Vladimir Kogan, and Alan Kalish from The Ohio State University assess the efficacy of utilizing modified introductory language on reducing the bias gap in student evaluations of instructions for women and minorities.

Key Points: 
  • In the new article " Mitigating Implicit Bias in Student Evaluations: A Randomized Intervention " published in the Applied Economics Perspectives and Policy, Joyce Chen, Brandon Genetin, Vladimir Kogan, and Alan Kalish from The Ohio State University assess the efficacy of utilizing modified introductory language on reducing the bias gap in student evaluations of instructions for women and minorities.
  • First, our data suggests that the treatments have a statistically significant effect on the likelihood of a response.
  • For example, the combined treatment discussing both implicit bias and high stakes tended to reduce response rates among students of color while the same treatment saw minority instructors have higher response rates from female students.
  • Although we find the high stakes treatment leads to higher average scores for racial/ethnic minority instructors, we find no significant effects from the implicit bias and combined scripts.

  • The expenditure elasticity of price is less elastic for PBMA relative to that for meat, but consumers are willing to purchase more PBMA if they are under promotion.
  • Also, the demand for PBMA responds most significantly to its own price change compared to that of other meat options, especially after the outbreak of COVID-19."

Key Points: 
  • This merger raised antitrust concerns because dairy farmers benefit from higher milk prices, but milk processors benefit from lower milk prices.
  • Small farms feared that a large dairy cooperative that buys the largest milk processing company might monopolize the milk market and raise prices.
  • This research investigates whether a hypothetical merger affects the market price of cow's milk and by how much.
  • Projected effects of a dairy merger " released in the Applied Economic Perspectives & Policy, looks at the impact of a hypothetical merger.
