[pt] Este trabalho tem como objetivo testar se cone de volatilidade aplicado ao mercado de opções brasileiro pode trazer informações adicionais à decisão de compra e venda de volatilidade. Outra contribuição deste trabalho é mostrar se os efeitos do sorriso de volatilidade e da estrutura a termo da volatilidade persistem diante de operações realizadas com o cone de volatilidade.Os resultados indicam que a comparação da volatilidade implícita com o cone de volatilidade pode ser um indicador eficiente para prever a evolução da volatilidade futura. Além disso, não só foi evidenciada a eficiência do cone como há indícios de que os ganhos são ainda mais acentuados para operações com opções dentro-do-dinheiro. Quanto a operações com opções de curto e médio prazo de duração até o exercício não existe índicos suficientes que comprovem a diferença nos resultados obtidos com a utilização do cone de volatilidade. / [en] The present study has the objective of testing if the volatility cone applied to the option market can improve the decision process of buy and sell volatility. Another contribution from this study is to assess if the volatility smile and the term structure of volatility persist when the volatility cone is used to build some operation.The results indicate that the balance of implied volatility and the volatility cone can be an efficient indicator to forecast the tendency of future volatility. Moreover, there are some indications that in-the-money options yield better results than others. On the contrary, there is no indication that short-term and medium-term options yield different results when using the volatility cone.

The practice of promoting food to children via advergames is a highly topical issue which attracts much concern due to the low nutritional value of the promoted foods. This thesis examines the effects of customised food advergames on children’s affective, cognitive and conative responses. It also investigates the role persuasion knowledge and prior brand usage have in children’s interaction with advergames. In particular, whether children’s persuasion knowledge acts as a barrier to those responses. This research is situated within the domains of marketing communications, consumer behaviour and consumer socialisation. It adopts an affect transfer theory, the Dual Mediation Hypothesis (DMH), to explain the transfer of affect from an advergame to children’s responses. Three versions of the same advergame were designed for the purpose of this thesis with different levels of customisation (i.e. control, low and high experimental conditions). An experiment among younger (5-7 year olds) and older (11¬12 year olds) children reveals that customisation in advergames has a detrimental effect on children’s affective, cognitive and conative responses. It was the control condition, without customisation options, that rendered a positive impact on brand attitudes and preferences relative to the other two experimental conditions. Persuasion knowledge does not influence children’s affective, cognitive or conative responses. This implies that children’s understanding of the persuasive intent of an advergame does not act as a barrier against its effects. Age had a significant role on children’s attitudes towards the advergame, but not on their other responses to it. Finally, prior brand usage has a positive impact on children’s responses apart from on advergame attitudes. This thesis has implications to policy and practice. It is evident that children from two distinct age and cognitive developmental groups cannot protect themselves from advergames’ effects. Therefore, regulators should broaden the scope of concern to older and younger children alike.

While research has shown the positive impact of sensory cues and cue- congruency on emotion and behavior in retail store atmospheres, these cues have primarily been investigated in isolation or in pairs. Consequently, little is known on how multi-sensory cues in interplay impact on consumer emotions and purchase behaviors. In addition, research has not yet provided any clear conceptualization of congruency in marketing when designing retail store atmospheres, other than stating that some cues are expected to match, therefore become pleasantly perceived. Thus, the main purpose of this research is to examine and show how multi-sensory cues in interplay and congruency can be utilized in creating a retail store atmosphere to enhance consumer emotions and purchase behaviors. To address the purpose, a sequential method was adopted with four essays. The first essay explores multi-sensory interplay in marketing contexts with a literature review that forms the basis for a research agenda. The second essay employs focus groups to highlight the congruency between cues, products and the retail setting, and identifies which category of cues is in need of investigation. The third essay uses field experiments to investigate two congruent visual, auditory and olfactory cues (six cues in total) in a retail setting, and their impact on consumer emotion and purchase behavior. The final essay, also use field experiments to examine and duplicate one cue from each sense, and employs these together in interplay, to show how multi-sensory cues in interplay impacts emotions and purchase behaviors. This research concludes that multi-sensory cues in interplay in a retail store atmosphere have a greater impact on consumer emotions and purchase behaviors than single visual, auditory and olfactory setting-congruent sensory cues. Among single sensory cues, those perceived as complementary in the atmosphere, specifically auditory and olfactory in an already visual dominated atmosphere, have the largest impact on consumer emotions and purchase behaviors. Overall, this research signifies that congruent multi-sensory cues in interplay emerge as reliable predictors for the influence on consumer arousal, valence, time spent, touching, browsing and purchasing Theoretical and managerial implications are discussed.

The main research objective of this study was to find out whether perceived value significantly affects consumers’ purchase intention. Additionally, this study examined if there are any significant differences in perceived value for different fast-food restaurant brands and attempted to identify which fast-food restaurant is perceived to be the industry leader. A total number of six fast-food restaurants (McDonalds, Subway, Starbucks, Wendy’s, Burger King, and Taco Bell) were selected. Findings showed that among the five perceived service value dimensions, Starbucks is the leader in terms of quality, emotional response, and reputation. Multivariate analysis of variance (MANOVA) and multiple regression analysis were performed to test the study hypotheses. Results indicated that there were significant differences in perceived value for different fast-food restaurant brands. Besides, monetary and behavioral price significantly affects consumers’ purchase intention. Findings are expected to help hospitality marketers to strategically manage their brands.

The master thesis covers the topic of company purchasing of own shares. In the meantime, this kind of process in the life of a company has been completed by another important phenomenon -- financial assistance -- which is the second topic of this thesis. The thesis aims to analyse the changes, that have been noticed in the Czech system of law, concerning the company purchase of own shares and the financial assistance during the last eighteen years, i. e. since the Commercial Code entered into force in the Czech Republic. There are also included the reasons of the legal regulation of the process of purchasing of own shares, that are of economic, legal even ethic character. In fact, the company law in the Czech Republic has been influenced in a significant way by the European sources of law, as well as the other branches of law. Thus, the evolution of the European legal framework of the company purchase of own shares and the financial assistance, and its impact on the Czech company law, have to be mentioned. To be more illustrative, the thesis refers to the judicature of the Supreme Court of the Czech Republic, to the judicature of the Court of Justice of the European Union, and standard practice of the Securities Commission.
