Vplyv dane z finančných transakcií na kvalitu trhu: Príklad Francúzska a Talianska
Šramko, Filip ; Jílek, Josef (advisor) ; Slaný, Martin (referee)
This thesis explores the impact of securities transaction tax (STT) on stock market quality. In order to identify the effects of STT on trading activity and market quality two recent STT introductions in France and Italy are analyzed. The effects are observed on panel data in four periods utilizing several trading activity and market quality measures. Following previous literature difference-in-differences approach is applied using various control groups including German and Spanish equities. The results point to significant decrease in trading activity and increase in bid-ask spreads in France following STT imposition. The impact on volatility is statistically insignificant across different specifications and estimation periods. The results for Italy are inconclusive due to possible contamination by political events, but the evidence indicates decrease in trading activity following STT introduction.

Šembera, Tomáš ; Potužák, Pavel (advisor) ; Čermáková, Klára (referee)
The bachelor thesis deals with potential of digital currency Bitcoin to become universally accepted medium of exchange and with advantages, which its usage would bring to economy. In the thesis there are analysed factors important for its future progression. There are identified both positive and negative factors. Among the positive ones there is pseudonymity, low transaction costs, protection against government actions and inovative potential in the field of financial services. Among the negative ones there is the question of the system security, network effect, the risk of government against Bitcoin itself and high volatility. Volatility of bitcoin valu is identified as the major disadvantage of the currency. Next part of theoretical part deals with the confusion about virtual currencies and regression theorem. Logical analysis suggests that this confusion is caused by wrong interpretation of regression theorem, which is mostly caused by improper understanding of the term direct use. In the next part, Bitcoin is analysed from the view of the Austrian business cycle theory. Because of the inability of performing credit expansion, Bitcoin is identified as currency significantly limiting the strenght of business cycles. Practical part analysis the developement of volatility in time and its dependence on events and spekulative demand. The hypothesis, that high volatility of bitcoin value is caused by immaturity of the technology is not confirmed.

Fundamental analysis of volatility of spot rate
Vasiľ, Roman ; Mandel, Martin (advisor) ; Brůna, Karel (referee)
This bachelor thesis deals with the exchange market, its size, structure and current status towards other markets. It describes an important indicator of the progress of the exchange market and its development, function and volatility. This indicator is called exchange rate. This work mentions various theoretical approaches which deals with the determination of the exchange rate going through the first theoretical models up to contemporary complicated understanding fluctuation of the exchange rate. There is also mentioned how the single theories deals with the factors which affect exchange rate, what is their pros and cons at the theoretical level and also at the empirical level. It prooves empirically the failure of the theoretical approaches through the factors which are not mentioned in the theory and the failure of various assumptions which are not achievable in present open economy in the area of the member states of the European Union.

Volatility Modeling of the PX Index
Dvořáčková, Anna ; Borovička, Adam (advisor) ; Zouhar, Jan (referee)
This thesis is focused on modeling of the real financial time series of the PX Index using linear and nonlinear volatility models. In the theoretical part the major terms and typical properties of the financial time series are presented and it is followed by the theoretical description of the linear and nonlinear volatility models including a general volatility model building. The key part of this thesis is the practical application of chosen linear and nonlinear volatility models on the time series of log returns of the PX Index. By using the real data set we verify if the volatility models are really capable of explaining the theoretical properties of the financial time series, such as volatility clustering, leptokurtic distribution and leverage effect.

Price of Volatility of Financials Assets
Gříšek, Lukáš ; Černý, Michal (advisor) ; Chrobok, Viktor (referee)
This diploma thesis describes problem of change-points in volatility of the time-series and their impact on price of nancial assets. Those change-points are estimated by using statistical methods and tests. Change-point estimation was tested on simulated datas and real world driven datas. Simulation helped to discover signi cant characteristics of change-point test, those data were simulated with using stochastic calculus. Google share prices and prices of call options were chosen to analyse impact of volatility change on those prices. Also implied volatility and its impact to call option price was analysed.

Analysis of the stock index volatility on European stock exchanges
Švehla, Pavel ; Hušek, Roman (advisor) ; Pelikán, Jan (referee)
This thesis focuses on analysis and comparison of volatility on selected European stock markets. At first paper briefly introduces the reader to the specific features of financial econometrics and the importance of asset returns volatility analysis. Further chapters precisely cover the construction of linear and nonlinear conditional heteroscedasticity models as an appropriate tool for describing the volatility in financial data. The empirical part of the thesis analyze four stock exchange indices from various European regions and seek appropriate models to express volatility behavior in period before the financial crisis in 2008 and also during the crisis phase. Based on selected models, the paper tries to compare the volatility in both periods within the specific stock market index and moreover between different regions. The last section examines asymmetric effects in volatility of stock indices using their graphical representation.

The CZK yield curve analysis and its application for the ALM analyses
Walos, Michal ; Dvořák, Petr (advisor) ; Tuček, Miroslav (referee)
The diploma thesis deals mostly with interest rate risk issue. It describes the basic methods of interest rate risk measurement with use of analyses executing by Asset Liability Management department in banks. Such analyses as repricing GAP, net interest income analysis, market value of equity and sensitivity analyses to interest rate movements. There is an analysis of Czech crown yield curve as well, in order to deeper insight of its probability behaviour. Results of this analysis are used for advanced techniques in ALM. Especially knowledge of volatilities of particular yield points and theirs relations is used in these methods. There was also a multi equation model for predictions of yield curve development created. One of the variables in the model there is the 2-week repo rate of Czech National Bank included.
