Influence of Quality on Comipetitivity of Milk and Milk products
Hrubá, Renata ; Kovářová, Kateřina (advisor) ; Čechura, Lukáš (referee)
Globalization requires a new understanding of the effect of attitudes in the decision making process, particularly when regional differences arise from different cultural and social norms. Information behavior is the part of behavioral economics that explores decision making stakeholders - consumers, businessmen or politicians, under conditions of bounded rationality. For consumers it is primarily important to buy local products from family farms. The aim of the thesis was to verify the effectiveness of that model in the Czech Republic, especially to fill in the empirical aspect of behavioral economics, relating to consumer behavior under unclear information as well as normal environments, thus understanding the indirect effect of perception on product information. Today these issues are gaining in importance in developed countries as well as in the Czech Republic. The high probability of "never researching product information" resides more within consumers with negative attitudes toward global issues (30%) than in consumers with positive attitudes towards those issues (about 1%). Attitudinal changes affect decreases among those "never searching for product information" (by 30%) as well as increasing "search-rates" (by 60%). In other words, the changes in attitude have significant effects on consumer behavior (Spillover effect). Predicting decision making behavior under unclear information also shows important results. Changes of attitude toward nutrient security, milk of origin or ingredients is associated with relative changes in behavior. A change of attitude will reduce the probability to sometimes buy products with unclear (15%) and increases the probability of buying products with clear information (17%). Empirical research of behaviors under uncertainty are long-term projects, however methodologies may vary differentially. By connecting the theory of planned behavior to the theory of information, these theses fill in the issues of behavioral economics theory. The practical implication is a methodological approach of the model.

Economics of Biased Estimation
Drvoštěp, Tomáš ; Špecián, Petr (advisor) ; Tříska, Dušan (referee)
This thesis investigates optimality of heuristic forecasting. According to Goldstein a Gigerenzer (2009), heuristics can be viewed as predictive models, whose simplicity is exploiting the bias-variance trade-off. Economic agents learning in the context of rational expectations (Marcet a Sargent 1989) employ, on the contrary, complex models of the whole economy. Both of these approaches can be perceived as an optimal response complexity of the prediction task and availability of observations. This work introduces a straightforward extension to the standard model of decision making under uncertainty, where agents utility depends on accuracy of their predictions and where model complexity is moderated by regularization parameter. Results of Monte Carlo simulations reveal that in complicated environments, where few observations are at disposal, it is beneficial to construct simple models resembling heuristics. Unbiased models are preferred in more convenient conditions.

Application of Game Theory to Analysis Conflict Situations
DOUBRAVOVÁ, Hana
This text describes basic types of games and their application into conflict situations. This text deals especially with decisions taken under risk and uncertainty. In application study the goods order of retail business is analysed. The task is to determine the optimal amount of goods orders to maximalize the company profit. This problem is solved by several ways, which are compared in conclusion.

Multi-Criteria Analysis and its application in practice
DOUBRAVOVÁ, Hana
This work deals with Multi-Criteria Analysis which represents an effective tool for solving complex decision-making situations. This paper describes the various methods of multi-criteria evaluation. One of the chapters also focuses on the software support. The main objective of this document is to demonstrate how to apply Multi-Criteria Analysis in real life. The practical part of this study refers to the structural policy and deals with the evaluation of regions of the Czech Republic after its entry into the European Union. The study mainly concentrates on the detailed analysis of South Bohemia region.
