The purpose of this study is to examine post-purchase evaluation factors influencing repurchase intention of credence products, and develop a model of consumer’s post-purchase evaluation for the repurchase intentions. The credence products in this case are dietary supplements, with a focus on consumers in Thailand. The study classifies a conceptual model and hypothesised relationships into two consumer perspectives: product; and brand. This research assumes that trust, expectations, satisfaction factors may relate to repurchase intention for the consumer product perspective. Also, brand trust, brand experience, expectation, and satisfaction factors are correlated with repurchase intention from the consumer brand perspective. The research adopts a hypothetico-deductive method to enable the testing of hypotheses and also a structural equation modelling (SEM) to measure the constructive relationship and regression analysis that evaluates the relationship between independent and dependent variables. Both simple regression and hierarchical multiple regression analysis were used to examine the effect of post-purchase evaluation factors on repurchase intention. These analyses are based on a sample of 504 dietary supplement users of vitamins, minerals, and herbs or other botanical products in four regions of Thailand through face-to-face structured interviews. Findings indicate that from consumers’ product perspective, consumer trust has no significant direct effect on consumer repurchase intentions whereas the relationship between consumer trust and consumer repurchase intentions of credence products are related, when it is mediated by consumer expectation and consumer satisfaction. In terms of consumers’ brand perspective, the study leads to a better understanding of consumer brand trust and consumer expectation, both of which have no significant direct effect on consumer repurchase intentions. Consumer brand trust, consumer brand experience and consumer repurchase intentions are not correlated when mediated by consumer expectation. Other findings reveal that brand experience has a direct impact on repurchase intentions whereas consumer satisfaction is a significant mediating factor when connected with: (1) the relationship between consumer brand trust and repurchase intention; (2) the relationship between consumer brand experience and repurchase intention. The study makes a contribution to a post-purchase evaluation for repurchase intentions of credence products from both consumers’ product and brand perspectives in Thailand. This study also suggests that consumer brand experience is the strongest factor and consumer satisfaction is the strongest mediator for consumers’ P-PE for the repurchase intention of credence products. From a managerial perspective, the findings of this study provide evidence for both the public and private sector in Thailand in terms of devising marketing strategies in accordance with this model.

This thesis presents two chapters on credence goods and one on ongoing partnerships in an infinitely repeated game. The chapters on credence goods focus on the welfare and efficiency of equilibria in overcharging models of credence goods, something which has not been explicitly addressed before. The chapter on partnerships presents a theory explaining ongoing partnerships as solving a commitment problem for clients. There is a small literature on partnerships, and this chapter represents a novel but complimentary approach to that literature. At core, chapters 2, 3 and 4 of this thesis ask the following questions respectively: Do competition and information increase welfare in credence goods markets? How do customers in credence goods markets discipline experts from committing fraud? Can these strategies be welfare ranked? Why do ongoing partnerships exist? What problem do they solve?

Given the credence nature of food quality and food safety attributes, consumers cannot easily verify whether food is high quality or is safe to eat, thus they rely on abstract systems of regulation and quality signals such as brands to make informed consumption choices. In fact, trust is recognized as a rational strategy that reduces consumers’ uncertainty when purchasing goods with credence attributes. While trust in food is a topical issue in an era of increasingly complex food systems, how trust and more precisely brand trust affects consumers’ perceptions of food is a relatively new research area in food economics. This thesis aims to answer questions such as what drives trust in the actors within the Canadian food system (i.e. government, farmers, food manufacturers, and food retailers) and in food brands, and the relationship between that trust and consumer confidence in food quality and food safety. Previous studies on institutional and system trust have been carried out primarily in the sociology, marketing and political sciences disciplines, while a few studies in food economics have investigated the influence of institutional trust and reported the degree of public trust in market actors. This study extends previous research on consumer trust in the context of food by developing a conceptual model in which trust in the food system and brand trust are expected to evolve to public confidence in credence attributes and lead to consumer commitment to food brands. Inspired from a comprehensive synthesis of the literature on consumer trust, the theoretical background suggests that consumer confidence in food attributes is jointly determined by trust in the food system (system-based trust) and brand trust (product-based trust), and it is moderated by consumer characteristics (personal-based trust) – namely: risk, past consumption experience and ethically-motivated behaviour. As well, consumers are assumed to perceive an actor or a brand as trustworthy through the influence of four postulated dimensions of trust: perceived competence, credibility, benevolence and reputation. A Structural Equation Modelling (SEM) approach is used for the empirical analysis. Data were gathered through an online survey of consumers conducted across Canada in July 2012 focusing on fresh chicken and packaged green salad products. The results show that individually none of the postulated antecedents of trust (i.e. competence, credibility, benevolence and reputation) was a significant driver for trust, especially for packaged salad. Unlike previous research on institutional trust and brand trust that uses a number of separate dimensions to measure trust predominantly in non-food contexts, this thesis finds that trust in the food system and food products could be measured differently by taking into account the interactive effects of perceived competence, credibility, reputation and benevolence on public trust. As such, the findings suggest that Canadian consumers tend to trust brands of chicken and packaged salad when these products are perceived as high quality, are backed by credible information, have a good reputation and, at the same time, enhance consumers’ welfare. In fact, a brand cannot be perceived as high quality and safe to eat (brand competence) without containing transparent information signalling its quality and safety (brand credibility). Additionally, results reveal some apparent product-specific effects: brand trust matters in fostering consumer confidence in chicken but not for salad. Furthermore, trust in the food system as a whole appears to be more influential in leading to public confidence in credence attributes than trust in food brands in the case of chicken. As such, it appears that trust in actors within the food supply chain is more important than relying on individual products. As well, the analysis shows that while psychographic variables (risk aversion, past consumption experience) and some demographics (e.g. gender, education) moderate the relationship between trust in the food system and brands for chicken, this is not the case for salad. In terms of marketing implications, the results suggest that while brands are useful signalling mechanisms, trust in these brands is not the main driver for consumer confidence in credence attributes. Furthermore, the much stronger effect of system trust implies that decision-makers would benefit by investing in building trust relationships with the public. Transparent communication and credible assurances about the practices and the intentions within the food system could be a way to gain and maintain public trust and, ultimately, consumer confidence in food quality and food safety.

<p>  This dissertation has two essays that are focused on understanding the effects of technology adoption decisions made by smallholder farmers who have incomplete information. The first essay employed a clustered randomized control trial (RCT) with factorial design in upper Eastern Kenya to estimate the impact of three different interventions at improving credence attributes of smallholder farmers’ maize. This essay also utilized a Becker DeGroot Marschak auction method to determine if farmers were willing to adopt a credence technology, and if yes, if their willingness to pay varied based on having previous experience with this agricultural technology. The second essay used the 2018/19 Ethiopia Socio-economic Survey to analyze the impacts of three sources of measurement error caused by farmers’ misperceptions on maize yields. Moreover, this essay explored how farmers’ incomplete information about adoption of one agricultural input led to misallocation of other complementary inputs. </p>

Pojetí výchovy u Jana Amose Komenského John Amos Comenius 's Approach to Education Petra Bochenková Jan Amos Comenius as a great thinker of the 17th century created a complete and comprehensive system that remained in his time misunderstood. After the Battle of White Mountain he was the greatest writer of emigration, philosopher, theologian, bishop of the Unity of Brethren. Last but not least, teacher and humanist. It should be appreciated Comenius theological importance of the creative effort, since the absolute top of the intellectual system is the existence of God. Throughout his working life has led to harmony and peace in the world, came up with the idea Pansophia. Pansophia trader a perfect connection and knowledge of all matters of life and the greatest possible realization of perfection. Opened the way to God. We can say that his ideas reached timelessness and especially in educational matters. Its comprehensive educational system can be applied in the field of education even today. His esteem gained mainly by its content overlaps with many, many areas of science and life. He sought to promote humanity and emphasized man as the pinnacle of God's creative efforts, which in his time represented something quite extraordinary. Preferred activity of theory and practice in all areas of life. The...

Cette thèse a pour objectif d'étudier les programmes de labellisation environnementale. Dans un premier temps nous différencions deux types de programmes de labellisation, les programmes de type ISO I qui donne une information discrète (les produits sont labellisés ou non), et les programmes de type ISO III qui eux révèlent l'information de manière continue (les cartes énergétiques). Nous montrons que les programmes de type de ISO III conduisent à des problèmes d'auto-sélection au sein de la ligne du produit du monopole alors que les programmes de type ISO I permettent à celui-ci de parfaitement discriminer entre ces produits. Ensuite dans un second chapitre, réalisé en collaboration avec J.W. Maxwell et R. Harbaugh, nous faisons l'hypothèse que le consommateur n'a qu'une idée incertaine de la difficulté du standard qu'un produit doit atteindre pour être labellisé. Nous montrons que la prise en compte de cette hypothèse diminue les incitations des entreprises à se faire certifier et l'efficacité des programmes de labellisation. Nous prouvons aussi que les entreprises choisissent de manière stratégique entre les différents labels disponibles sur le marché. Enfin dans un dernier chapitre réalisé en collaboration avec J. Rosaz et F. Poinas, nous choisissons d'utiliser l'économie expérimentale afin d'étudier le comportement du consommateur ou plus précisément la révision des croyances d'un sujet lorsque celui-ci reçoit un signal imparfait. Le signal envoyé au sujet consiste en une restriction des états possibles de la nature et s'apparente ainsi au label observé par le consommateur sur le marché. Nous montrons qu'en moyenne ces signaux permettent aux sujets d'améliorer leur estimation, cependant certains signaux trop incertains peuvent avoir des effets pervers. / This thesis has for goal to study environmental labeling programs. In the first chapter, I use a self-selection model to study environmental labelling program in a context of multiproduct monopoly. I show that the manner by which information is conveyed affects the firm strategies. I prove that programs, which disclose continuous information such as report cards, can lead to self-selection issues within the monopoly product line, whereas those which give discrete information such as the EU flower allow the monopoly perfectly discriminating among consumers. In the second chapter, joint with J. Maxwell and R. Harbaugh, we relax the assumption that consumers know the exact standard that the product has to meet to be labelled. The uncertainty over the standard leads the consumers to jointly estimate the product quality and the standard difficulty. This undermines the ability of voluntary certification to reduce information asymmetry. In the third chapter, joint with J. Rosaz and F. Poinas, we analyze belief updating behaviors with imperfect signals in an experimental setting. The novelty of the paper is to consider a signal that restricts the set of the possible states of the nature. One of the objectives of this chapter is to study the consumer updating behaviors when they observe a label on a product but with the methodologies developed in the Bayesian updating literature. We show that this kind of signals increases the correctness of the subject estimations. However these signals can also let the subjects very uncertain about their estimation which can conduct to adverse effects.

This diploma thesis deals with the analysis of governance structures in the model of Community Supported Agriculture in the Czech Republic as one of the alternative forms of food production. The theoretical part describes the characteristics and defines the potential of Alternative Food Networks (AFNs) in the development of the region, also defines the term Community Supported Agriculture. Subsequent attention is paid to the process of transmission of this AFNs model to the Czech environment and to its current forms. The practical part presents three case studies on selected CSA groups in South Moravian region. These information served as the basis for subsequent analysis of governance structures of these groups. Based on the results of the analysis the real form of these initiatives was identified, equally as the identification of linkages between the key players. Finally, the overall performance of the model was evaluated. Results of the analysis indicate that presented potential benefits for the vital development of agricultural producers and development of local regions can not be considered as automatic even though there exist many examples of good practices abroad.

According to a prominent thought, in one’s practical reasoning one should rely only on what one knows (Fantl and McGrath 2002; Hawthorne and Stanley 2008; Williamson 2000, 2005a, 2017). Yet for many choices, the relevant information is uncertain. This has led Schiffer (2007, 189) to the following objection: oftentimes, we are fully rational in reasoning from uncertain premises which we do not know. For example, we may decide to take an umbrella based on a 0.4 credence that it will rain. There are various ways proponents of a knowledge norm for practical reasoning can respond. One option is to say that the right way of dealing with uncertain information requires knowledge of probabilities (Hawthorne and Stanley 2008, 581–85). Another option is to say that credences can be knowledge because they really are beliefs with an unusual kind of content that consists of a set of probability spaces (Moss 2018, chap. 9). Mixed accounts are possible as well (Weisberg 2013). On neither of the accounts in the literature, however, can reasoning from uncertain premises be taken as reasoning based on a graded attitude, a credence, toward an ordinary proposition. To make room for this possibility, I argue that reliance comes in degrees. The knowledge norm is only plausible when taken to be concerned with full reliance.Partial reliance, on the other hand, goes hand in hand with credence.
