Usability of contractual information for prediction of household energy consumption volume
Škorvaga, Cyril ; Janda, Karel (advisor) ; Khymych, Olha (referee)
5 Abstract This thesis investigates usability of contractual information, enriched with publicly available sociodemographic and environmental statistics, for predicting household energy consumption volume. The aim is to assess the usability of this type of information to enhance prediction accuracy as well as to uncover relationships between energy consumption and various independent variables derivable from the contractual information, such as appliance groups, location, age, and sex. Regression trees, a machine learning technique, are employed to develop a prediction model. Thesis focuses on households in the Czech Republic. The results demonstrate the efficacy of the prediction model, with low bias and improved accuracy compared to existing estimators for newly set meter points. The inclusion of regional-level variables enhances prediction accuracy only moderately. However, patterns derived from extensive datasets yield statistically significant conclusions regarding the effect of these variables. Challenges in incorporating certain variables and lack of longitudinal data limit the study. Future research directions may include exploring how different customer groups react to time- variant factors to enhance the accuracy and applicability of energy consumption predictions. The findings provide utility...
Estimating the Relationship between Food, Fuel and Biofuel Prices
Novotný, Matěj ; Janda, Karel (advisor) ; Khymych, Olha (referee)
Although biofuels have drawn the attention of researchers since its boom, which took place 20 years ago, doubts about benefits which their usage brings in the academic debate. This thesis joins the debate that discusses the impact of biofuels on food prices. The prices of 38 commodities and assets that are related to the biofuels are examined under Minimum Spanning Tree and Hierarchical Tree methods over the years between 2003-2019. The time span is divided into 4 periods, that responds to the development of world food prices. The results show that the relationship between biofuels and their feedstock depends on the overall level of food prices. In the case of higher food prices, the link between feedstock and biofuel is stronger and therefore the price transmission is more likely to happen. With lower food prices, this link is significantly weaker. Furthermore, the development of world food prices does not follow the trend of increasing biofuels production as food prices have become stable in recent periods. Therefore, this thesis does not support the claim that biofuels cause higher prices of food.

Determinants of Life Satisfaction in the Czech Republic and their Development over Time
Pavlovová, Anna ; Chytilová, Julie (advisor) ; Khymych, Olha (referee)
This work examines the reported life satisfaction in the Czech Republic over the period between 1991 and 2016. The relationships between various individual characteristics and reported life satisfaction are analysed using the ordinary least squares and the results are compared across time. This work extends the existing literature not only by providing a more up-to-date analysis of the correlates of life satisfaction in the Czech Republic but also by analysing them in a wider time horizon. Some relationships were found rather stable over the considered period (for example, those associated with health, satisfaction with institutions or with political beliefs). Even though higher education and higher income were not strictly associated with higher satisfaction, the differences in satisfaction of individuals belonging to the lower and upper deciles of income are significant throughout the whole period. On the other hand, some associations have changed substantially over time (e.g. those related to being a student). Contrary to the existing literature on the period of transition, life satisfaction in the Czech Republic appears to be U-shaped in age during the whole considered period including the 90s. However, the turning points and the exact shape of the relationship changed over time. Keywords life...

Czech Cross-Border Insolvency Rules in Comparison with the UNCITRAL Model Law
Martiník, Pavel ; Richter, Tomáš (advisor) ; Khymych, Olha (referee)
The Thesis compares UNCITRAL Model Rules on Cross-Border Insolvencies with current Czech legislation. In the first part, it briefly depicts main cross-border insolvency systems, as they were developed by leading scholars. Furthermore, the protocols, as a unique solution to a multinational default are discussed. In the second part, it applies principles of economic approach to law and discusses the pros and cons of the Czech system in comparison to the Model Rules using specific examples. The outcome of the Thesis is analysis of several features the Model Rules and Czech legislation differs. Powered by TCPDF (www.tcpdf.org)
Fuel Demand Elasticity on Car Fuel Taxes
Vágner, Dalibor ; Rečka, Lukáš (advisor) ; Khymych, Olha (referee)
The main focus of this thesis is to estimate the fuel demand elasticity on excise tax levied on gasoline and diesel. This work utilizes and subsequently develops the model and data set already published in the literature devoted to fuel taxation. The main contribution is the close analysis of the data from the Czech Republic and following comparison with the results from other countries. Furthermore, this paper extends the model by allowing it to filter out interstate shifts in purchases induced by different fuel price levels in neighboring countries. The relationship between interstate price differences and domestic fuel demand is consequently analyzed.
