Beer Consumption Patterns in Europe
Zobal, Vladimír ; Janda, Karel (advisor) ; Špolcová, Dominika (referee)
This thesis intends to verify and quantify relationship between microeconomics, macroe- conomics and social variables with annual beer consumption per capita. To assess dif- ferences in tastes in groups of countries, the concept of beer, wine and spirit drinking countries is used to separate the influences. Firstly, the general model for all European countries is estimated with the use of panel data techniques on data from 2000 to 2013. The results and findings from the first model are subsequently used as a building blocks for specific model for The Czech Republic. The Czech Republic has over a long period the highest annual consumption per capita. Still the share consumed in hospitality expe- riences persistent downward trend. All data are collected on annual basis and with only country-aggregated level of detail.

The Impact of German Renewable Electricity on Czech Electricity Spot Prices
Kouřílek, Matěj ; Baruník, Jozef (advisor) ; Janda, Karel (referee)
Thesis investigates the impact of German wind and solar energy on the dynamics of Czech electricity spot prices in the period between 2015 to 2018. Using pooled panel-GARCH model, a negative merit order effect of German wind and solar energy were observed. More specifically, one additional GW of power produced by wind and solar, reduces the spot price by 0.60 and 0.45 EUR/MWh, respectively. The negative merit order effect was also found in the case of Czech solar energy. Corresponding spot price reduction equals to 1.42 EUR/MWh per additional gigawatt hour. Next, increased volatility in the spot prices was found due to both German wind and Czech solar energy. I also observed that these effects differ during a day. Furthermore, I estimated total financial impact stemming from the negative merit order effect and compared it with the total costs of households that arise in surcharges to support renewable energy. While Czech households pay approximately 270 million euros annually in surcharges, the total financial impact stemming from the merit order is around 145 million euros. The value comprises the merit order effect of both Czech and German renewable sources. In other words, Czech and German households bear the costs of subsidized renewable energy while they do not necessarily profit on the merit...
Biofuels-economical and ecological impact
Kalous, Václav ; Janda, Karel (advisor) ; Herman, Dominik (referee)
Bachelor's Thesis Proposal Institute of Economic Studies Faculty of Social Sciences Charles University in Prague Author's name and surname: Václav Kalous E-mail: vaclavkalous1@gmail.com Phone: 731214182 Supervisor's name: prof. Ing. Karel Janda, M.A., Dr., Ph.D. Supervisor's email: Karel-Janda@seznam.cz Notes: Please enter the information from the proposal to the Student Information System (SIS) and submit the proposal signed by yourself and by the supervisor to the Academic Director ("garant") of the undergraduate program. Proposed Topic: Biofuels- economic and ecological impact. Preliminary scope of work: Research question and motivation The issue of provision of energy for the vast population of planet Earth remains one of the biggest challenges for the humankind today. Sources such as fossil fuels are limited and will be depleted one day, so it is evident that we must seek for renewable resources to provide for our everyday needs. Even though complete depletion of fossil fuels is still quite far away, new energy resources are already on the scene. This is mainly due to environmental reasons, because fossil fuels are in fact believed to be the worst possibility from the ecological point of view. One of the frequently used renewable resources are biofuels, however these are subject to controversy because...
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.

Riziko spojené se změnami počasí na trhu se zemním plynem
Vyležík, Tomáš ; Janda, Karel (advisor) ; Gapko, Petr (referee)
This thesis deals with the impact of weather on the natural gas market. We describe the development of the natural gas market in recent past and its current structure. Both these contingencies contributed to growing importance of hedging against weather risk today. Consequently, with help of regression models we assess the dependency of Czech natural gas consumption on temperature, which is unambiguously the primary determinant of demand in the natural gas market. Such an analysis frequently serves as the first indicator of the need for weather risk hedging, which is since the 90's commonly done with weather derivatives. Therefore we go through so called burn analysis that determines the fair price of an option with regard to past temperature measurements.
Soft Budget Constraint and Financial Crisis
Seifert, Jan ; Janda, Karel (advisor) ; Hlaváček, Michal (referee)
This work attempts to describe the role of soft budget constraint in the mature economies. The main attention is paid to the revival of the notion "soft budget constraint", because we assume that because of the current financial crisis it is important to focus on this problem. This work focuses mainly on the analysis of the U.S. financial sector, because this sector was hit by the financial crisis the most. Our effort is to find out whether the U.S. environment provides sufficient conditions for appearance of the soft budget constraint. We are especially interested in the assumption whether it is relevant to assume the presence of the soft budget constraint in the bank sector and in the consequences of its presence. Here we stress the importance of institutions and the current form of the bank sector. The next step is to analyze if under current conditions there is a positive probability that some U.S. firms do have soft budget constraint. The final part of this work covers the problems of soft budget constraint 5 and financial crisis. We analyzed a few possible solutions for the current financial crisis and compare its effects on soft budget constraint appearance in the U.S. economy.
Vliv dividendové politiky na hodnotu firmy
Říhová, Jana ; Dědek, Oldřich (advisor) ; Janda, Karel (referee)
This thesis is focused on the dividend policy in the Czech Republic. We describe the basic about dividends as types of dividends, process of declaration and payments, dividend-paying methods, determinants which can influence the dividends and so on. The main part is devoted to the issue of dividend policy in the Czech Republic and its impact on the firm value. We use the event studies, based on observing the abnormal returns to shareholders around the record date. Then we apply regression of abnormal returns on relevant explanatory variables. And we also make an analysis of some of explanatory variables, as volume and dividend yield. Finally, we also shortly mention the share repurchase, the alternative to the dividend payout.
Volatility spillovers between crude oil and food commodities
Hrycej, Martin ; Krištoufek, Ladislav (advisor) ; Janda, Karel (referee)
In this thesis, we analyze volatility spillovers between crude oil and food commodities. The principal hypothesis assumes crude oil to behave as a production factor of the agricultural food commodities, thence we are looking for appropriate price effects. We mainly employ wavelet coherence and partial wavelet coherence, which provide us with valuable insight into the commodities nexus, without any strict restraints and assumptions levied on our data. Secondly, we build a DCC-GARCH model in order to model the presumed volatility spillovers. We also perform several simple benchmark analyses, in particular we test for Granger causality and we compute the Pearson correlation coefficients. Our data sample, including 10 commodities and 2 indices, covers the latest decade, significantly widening the existing contextual literature. Our results are mostly compliant with related literature, especially regarding the crude oil-fuels bundle and food commodities bundle, respectively. Considering the main research question of volatility spillovers between food commodities and crude oil, our results are indicating reasonably strong relationships with crude oil for soybeans and corn, leaving cotton and wheat rather on the verge of strong relationship and finding cattle to be completely unrelated. Main merits of the thesis...
Evaluation of Residual Shape Risk: Gas Energy Markets
Kouřílek, Jakub ; Janda, Karel (advisor) ; Schwarz, Jiří (referee)
The thesis evaluates and quantifies the residual shape risk on the Czech nat- ural gas market. The risk stems from insufficient liquidity of forward mar- ket, when energy supplier has to hedge his short shaped sales by standard baseload products available at wholesale market. Hence, energy supplier is always left with residual position, which has to be closed at spot market. We model the residual shape risk as a difference between spot and forward prices weighted by residual position, which is derived from the shape of innogy En- ergie, s.r.o. household portfolio. In order to do so we develop model for a spot price dynamics based on the daily index OTE. We price forward contracts as expected spot price at delivery. The spot price dynamics is modelled as a mean-reverting Ornstein-Uhlenbeck process, while assuming two different driving stochastic processes for innovations. First, we model them as a mixed jump diffusion process. Second, we estimate control model assuming innova- tions to come from the normal inverse Gaussian distribution. The residual shape risk is then evaluated by Monte Carlo simulation of spot price paths, which we use for hedging the portfolio shape. Five percent Value-at-Risk and the Expected Shortfall measures for the jump mixed diffusion process yield costs of 0.013 and 0.016 EUR/MWh,...
The Role of Tax Havens for Banks: Evidence from Two Firm-Level Datasets
Jelínková, Eliška ; Janský, Petr (advisor) ; Janda, Karel (referee)
Thesis: The Role of Tax Havens for Banks: Evidence from Two Firm-Level Datasets by Eliška Jelínková The thesis focuses on the base erosion and profit shifting in the banking sector, a topic that has not been studied much so far. We are the first to compare Orbis data with recently available country-by-country reporting data on banks' economic activities. In Orbis data, we identify underreporting of the number of countries where bank groups operate, tax, or the number of employees while some of the profits seem to be missing in country-by-country reporting data. In the second part, we study the tendency of banks to shift their profits due to two incentive - either low taxation or high financial secrecy. We find that the locations of banks' profits are sensitive to statutory tax rates and that this elasticity is higher at higher levels of statutory tax rates while effective tax rates do not seem to affect banks behavior. For the first time in this context, we use the secrecy score of the Financial Secrecy Index to analyze the secrecy incentive to shift the profit but we do not find any significant evidence that financial secrecy influences banks' behavior. Finally, we provide the first analysis of whether the obligation to disclose information on the country basis from the year 2014 has any effect on...
