Unemployment in the Czech Republic
Klečka, Michal ; Hlaváček, Michal (advisor) ; Kvaček, Jan (referee)
This paper is aimed at analysis of unemployment in the Czech regions. The key thing is the effort to create a simple model which determinates unemployment in regions. To this, three basic factors are used - inflation, outcome and criminality as they represent fiscal, monetary and social policies. Firstly, the effects of these factors are tested separately by OLS to find their mutual correlation. The average effects of dependence between factors and unemployment in regions are also established by using panel regression. Original and static Phillip's curves are used to measure the impact of level of unemployment on the inflation. The expanded model of Phillip's curve and the dynamic model of natural level of unemployment are used to estimate natural levels of unemployment in regions. The difference version of Okun's law is used to estimate the impact of economy outcome on the level of unemployment. Subsequently, the extended model of Okun's law is used to distinguish the effect of economic cycle on this impact. Correlation of level of unemployment with criminality is measured by simple model, where the change of the first variable is determined by the change of the second variable. All this knowledge is used to create the complex model, which explains the change of the level of unemployment in...

Resting energy expenditure during lacatation.
Klečka, Michal ; Hronek, Miloslav (advisor) ; Kovařík, Miroslav (referee)
Background The aim of diploma thesis was to evaluate resting energy expenditure (REE) and substrate oxidation in Czech lactating women and their relation to measured anthropometric parameters. Methods The indirect calorimetry was used to asses REE. Subsequently, the oxidation of substrates was calculated. At the same time were measured anthropometric parameters of breastfeeding women. Then the correlation was investigated. The total amount of examination were three times. First was in the time three weeks after birth, the second one was three months postpartum and the last was six months after birth. Results The mean values of REE in lactating women were 1577±93 kcal/day in the time of three weeks after birth. Three months after birth it was 1622±140 kcal/day. Six months after birth it was 1545±80 kcal/day. Significant positive correlation was proved between REE and triceps skinfold thickness (r = 0,98; P < 0,05) and also chest circumference (r = 0,99; P < 0,05). Both were three weeks after birth. Breastfeeding women had a value of lipid oxidation 60 % of substrate oxidation three weeks postpartum, which decreased to 46 % three months postpartum due to sharp increase (from 8 % to 18 %) of carbohydrate oxidation value. This increase could correspond to the preferential use of glucose by the mammary...

The impact of changing exchange rates on Czech companies
Klečka, Michal ; Baxa, Jaromír (advisor) ; Semerák, Vilém (referee)
This thesis analyses impact of exchange rate exposure in Czech Republic on sample of ten Czech companies. Empirical part of thesis builds on Nazl, Kar, Akel (2014) and through market-based approach states significant impact of exchange rate exposure for 40 % of companies. Higher robustness of results was achieved through improvements in the methodology which, contrary to related literature, eliminates endogeneity of market index through instrumental variable. Surprisingly, the correlations between exchange rates and stocks of Czech companies are positive. An alternative model considering ROA of individual companies as dependent variable was used to confirm these results. The resulting impact of exchange rate exposure of alternative model is opposite. This inconsistency of the results of both models is confusing. The sudden change in exchange rate policy of the Czech National Bank in November 2013 did not affect the sensitivity of the relationship between exchange rates and stocks. The reaction of stock market in November 2013 indicates that policy change made by CNB was not entirely expected. Contrary to the related literature, higher data aggregation decreases the significance of the exchange rate exposure, signifying higher ability of Czech companies to reduce exchange rate risk in longer...
