High prices of organic food are the main obstacle to the growth of the demand for organic food. This study’s main objective was to quantify the size of the gap between consumers’ willingness to pay more for organic food and the actual price premiums for organic food in Poland. Therefore, a two-step research study was undertaken. In order to identify barriers to the growth of organic food consumption and the perception of organic food prices, a survey based on an online questionnaire of 516 respondents was conducted. To determine price premiums of organic food, prices of organic and conventional food were quoted in 45 retail outlets offering organic and conventional food located in the Poznań agglomeration between October 2022 and June 2023. This research demonstrated a low acceptance of the high prices of organic food among consumers (only 14% of the investigated consumers were willing to pay more than 40% for organic food). On the other hand, the price premiums ranged between 35% and over 270%. To reduce the divergence, the measures supporting organic market development should be intensified with the simultaneous further involvement of supermarket chains. Along with these activities, the promotion of organic food ought to be carried out, considering that, as this research shows, men have fewer positive perceptions of organic food and, therefore, they should be targeted in the promotion measures.

Social media networks are increasing in popularity and have been integrated into many aspects of daily life. Analysis of the ways in which individuals use social media is important for understanding social, cultural, and environmental issues. This study examines experiences of farmers’ market customers through their self-expression on social networks. Contributions to the Instagram social network based on the #farmersmarket hashtag were gathered on a single day, yielding 19,398 contributions created by 13,862 users. Six major linked hashtags were identified (#Organic, #Fresh, #Food, #Local, #Vegan, and #Healthy), providing key indicators of the characteristics of farmers’ markets that are valued by customers. Four customer segments were identified: Product Oriented, Emotional Oriented, Social Oriented, and Product-Social Oriented, with strong interconnections identified between these communities. The results of this study provide insights into consumer values and behaviors in the farmers’ market context and will be of practical use for future marketing and management.

Food labels allow producers to promote the unique selling points of their products and help consumers buy products with value-adding qualities. The aim of the present article is hence to explore Czech food producers’ expectations and experience with selected food labels. The selection was narrowed down to enterprises that had succeeded in the certification processes within the food labeling systems of European quality and origin labels (protected designation of origin (PDO), protected geographical indication (PGI), and traditional specialty guaranteed (TSG)), as well as schemes that fall under the remit of the Ministry of Agriculture of the Czech Republic, such as Klasa (Česká potravina/Czech food, Regionální potravina/regional food, and BIO). The research was made using an online questionnaire in January–February 2018, and was focused on determining possible discrepancies in expectations that the companies had before applying for quality/origin labels and their actual experience with the labelling systems, the benefits they had gained, and their overall experience with the labels. To compare the respondents’ expectations and their actual experience, both the non-parametric Wilcoxon test and t-test were used. The results show that the respondents positively evaluated the effects of marketing communication, but their expectations had been higher than what they experienced.

The aim of this paper is to examine the communication content of Instagram social network users, on the basis of the hashtags they use relating to gamification and to define communities within the network in the context of education. The results are based on the analysis of Instagram's worldwide social network. Primary data were collected using a script to capture communication on the social network Instagram. The analysis included Instagram photos selected on the basis of hashtag #gamification (17,994 contributions). The results identify that the most commonly associated expressions with hashtags #gamification are hashtags associated with education and business, especially where startup and innovation are concerned. On the basis of an analysis visually isolated communities with average modularity of 0.506 were identified, which relate to the communication of the gamification on the social network Instagram: 1) Education, 2) Entrepreneurship, 3) Gamification in general, 4) Social and 5) Enjoyment. The benefit of analysis for the education area is to identify the university‘s links between Education and Entrepreneurship and the Teacher and Trust between education and enjoyment.

A major advantage of online organic produce shopping is the fact that it saves energy and reduces emissions otherwise generated by customers during their time spent on the road and while shopping. Organic products in general positively impact sustainability, the environment, and the regions of their origin along with the social changes in these regions and further rural development. Moreover, these products positively impact the perceived health benefits and quality of food labeled as organic. The Czech Republic has currently seen a rise in organic food purchasing and supply trends. This study maps the factors possibly influencing consumers’ decision to go shopping for organic food online. Observed factors include the following demographic characteristics of consumers (respondents): gender, age, education, household income, number of children in the household and number of household members. A total of 757 respondents from the Czech Republic from September 2020 to December 2020 took part in the research. Logistic regression, used for data processing, identified the statistically significant effects of education, income and number of household members on online purchases. These conclusions were confirmed by a detailed contingency tables analysis, including the almost monotonous trend of the dependencies, with only minor deviations in a maximum of one category. The strongest influence of some categories on the emergence of partial dependencies was found by residue analysis. The research confirmed that the frequency of online grocery shopping increases significantly with increasing education and income of respondents and decreases with increasing the number of household members. Most respondents apparently shop for groceries online because of time savings, better product choice and more convenient and easier search.
