This study investigated the relationship between capital structure, performance and replacement of chief executive officer in firms listed on the Nairobi Securities Exchange (NSE). Data was collected from a sample of 37 firms listed on the NSE over a period of 23 years, from 1990 to 2012. The analysis was conducted at three stages. The canonical correlation technique was employed to investigate the bi-directional relationship between capital structure and performance and to select competing indicators of performance and capital structure. Second, the general linear model (GLM) procedure was used to test the effect of performance and ownership structure and to test the effect of capital structure and ownership structure. Lastly, the generalised estimating equation (GEE) was used to assess effects of performance, capital structure and ownership structure on change in CEO. The results revealed that a bidirectional relationship exists between capital structure and debt capital. The indicators found to be useful in examining the relationship between performance and capital structure are asset turnover ratio and total debt to the total asset ratio. The findings support the efficiency hypothesis but not the franchise hypothesis. The results also indicated that firms with a low asset turnover are with a low asset turnover are 3.045 times likely to change CEO compared to firms with a high asset turnover. The results also indicated that firms with high leverage (debt) are he results also indicated that firms with high leverage (debt) are 3.430 times likely to change CEO compared to firms in low leverage, while the firms with medium leverage are are are are 6.491 times likely to change CEO. Therefore managers should not be passive when it comes to choosing between equity and debt capital played a disciplinary role on firms listed on the NSE. / Business Management / DCom (Business Management)

Cette thèse traite de la théorie du risque en finance et en assurance. La mise en pratique du concept de comonotonie, la dépendance du risque au sens fort, est décrite pour identifier l’optimum de Pareto et les allocations individuellement rationnelles Pareto optimales, la tarification des options et la quantification des risques. De plus, il est démontré que l’aversion au risque monotone à gauche, un raffinement pertinent de l’aversion forte au risque, caractérise tout décideur à la Yaari, pour qui, l’assurance avec franchise est optimale. Le concept de comonotonie est introduit et discuté dans le chapitre 1. Dans le cas de risques multiples, on adopte l’idée qu’une forme naturelle pour les compagnies d’assurance de partager les risques est la Pareto optimalité risque par risque. De plus, l’optimum de Pareto et les allocations individuelles Pareto optimales sont caractérisées. Le chapitre 2 étudie l’application du concept de comonotonie dans la tarification des options et la quantification des risques. Une nouvelle variable de contrôle de la méthode de Monte Carlo est introduite et appliquée aux “basket options”, aux options asiatiques et à la TVaR. Finalement dans le chapitre 3, l’aversion au risque au sens fort est raffinée par l’introduction de l’aversion au risque monotone à gauche qui caractérise l’optimalité de l’assurance avec franchise dans le modèle de Yaari. De plus, il est montré que le calcul de la franchise s’effectue aisément. / This thesis deals with the risk theory in Finance and Insurance. Application of the Comonotonicity concept, the strongest risk dependence, is described for identifying the Pareto optima and Individually Rational Pareto optima allocations, option pricing and quantification of risk. Furthermore it is shown that the left monotone risk aversion, a meaningful refinement of strong risk aversion, characterizes Yaari’s decision makers for whom deductible insurance is optimal. The concept of Comonotonicity is introduced and discussed in Chapter 1. In case of multiple risks, the idea that a natural way for insurance companies to optimally share risks is risk by risk Pareto-optimality is adopted. Moreover, the Pareto optimal and individually Pareto optimal allocations are characterized. The Chapter 2 investigates the application of the Comonotonicity concept in option pricing and quantification of risk. A novel control variate Monte Carlo method is introduced and its application is explained for basket options, Asian options and TVaR. Finally in Chapter 3 the strong risk aversion is refined by introducing the left-monotone risk aversion which characterizes the optimality of deductible insurance within the Yaari’s model. More importantly, it is shown that the computation of the deductible is tractable.

The graduation thesis deals with the use of logistics in the brewery Pivovar Protivín a. s. The paper presents a view of the current situation of Czech breweries in the Czech Republic as well as in the world. It maps the trends of recent years in the brewing industry and shows how Czech breweries have faced up the economic crisis. The results of Pivovar Protivín are presented and compared with the results of Svijany brewery. The distribution of Protivín brewery products is analyzed. Based on the analysis, the time frame of beer delivery to customers is made. Further on, the questions of the packaging management in Protivín brewery are dealt with. Breweries are specific for complex and expensive reverse logistics of returnable packaging. The question whether producing beer in PET bottles would be appropriate for Protivín brewery is studied. Determining the level of services provided for brewery customers is examined. According to the results presented here, the greatest demands on services provided by breweries appeared to be those by the customers in gastronomy sphere. Based on the questionnaire investigation, the standards in providing brewing services were set together. Finally, I suggested possible improvements that should lead to cost savings, greater flexibility of operations and competitive advantages for the Protivín brewery as well as for the whole K Brewery Group.
