The relationship between the lawyer and his client under the contract of mandate
Čech, František ; Patěk, Daniel (advisor) ; Horáček, Vít (referee)
Relationship between client and attorney-at-law according to mandate contract Resume This thesis examines the legal relationship between a client and an attorney-at-law who conclude a mandate contract. Its aim is to characterize the most important rights and obligations which arise in such a relationship in accordance with valid Czech legislation, judicial decisions and disciplinary practice of the Czech Bar Association. The thesis begins with a description of the special role of attorneys-at-law in the market of legal services among other professions that are involved in provision of these services. Then it focuses on the legal nature of a commercial mandate contract, its comparison with a civil mandate contract according to Czech law, and examines whether such differences in fact have any impact on the rights and obligations in the client and attorney-at-law relationship. After a short analysis of the possible legal causes of a creation of the legal relationship between a client and an attorney-at-law and I focus on the different rights and obligations which are the content of the relationship. I start with a description of the attorney's-at-law right for remuneration and the limits of this right, where I notice the different legal views towards a success fee. Then I explain the attorney's-at-law duty to...

Financial Stability Issues and Stress Testing of the Insurance Sector
Hauryliuk, Nadzeya ; Jakubík, Petr (advisor) ; Čech, František (referee)
The purpose of this thesis is to provide an overview of risk and vulnerabilities for financial stability of the European Insurance sector. The methods and principles of risk assessment are examined, as well as their application for the insurance sector. The current macroeconomic situation and its impact on insurers' financial stability is described. Downward changes of interest rates are identified as the biggest current risk. This results from a system-wide stress test conducted by EIOPA (European Insurance and Occupational Pensions Authority), analysis of sensitivities published by several big European Insurers published on a yearly basis and finally from an econometric analysis of the relationship between market data and changes in macroeconomic variables. Keywords financial stability, stress testing, insurance sector, insurance risks

Dynamic Portfolio Optimization During Financial Crisis Using Daily Data and High-frequency Data
Čech, František ; Baruník, Jozef (advisor) ; Krištoufek, Ladislav (referee)
This thesis focuses on variance-covariance matrix modeling and forecasting. Majority of existing research evaluates covariance forecasts by statistical criteria. Our main contribution is economic comparison of parametric and non- parametric approaches of covariance matrix modeling. Parametric approach relies on RiskMetrics and Dynamic Conditional Correlation GARCH models that are applied on daily data. In the second approach, estimates of variance- covariance matrix are directly obtained from the high-frequency data by non- parametric techniques Realized Covariation and Multivariate Realized Kernels. These estimates are further modeled by Heterogeneous and Wishart Autoregression. Moreover, our contribution arises from the use of dataset that covers period of financial crisis. Portfolio of assets that is dynamically optimized consists of two highly liquid assets - Light Crude NYMEX and Gold COMEX, and of European asset represented by DAX index. Forecast evaluation results indicate better economic performance of models estimated on daily data. However, we found out that data synchronization procedure is the main driver of the results.

Efficiency, predictability and liquidity in the commodity futures markets
Čermák, Vojtěch ; Krištoufek, Ladislav (advisor) ; Čech, František (referee)
This thesis examines efficiency of several CME commodity futures and its relation to market liquidity over the ten years period. The goal is to find ARMA model that is better than white noise in terms of forecasting power and carry out analysis of market liquidity if we find such model. This is done by comparing selected ARMA models to white noise. In order to do that, we use Diebolt - Mariano test on forecast errors obtained by pseudo out - of - sample analysis using rolling window with re - estimation. Concern of furhter analysis are factors, that can influence the DM statistics. Main findings are, that we are able to find such ARMA model for small enough time period within the ten years period for almost all commodities. For most commodities, this sub period is not long enough to violate efficient market hypothesis. Only for palladium and lean hog futures this period is longer than one year. These two futures shows strong signs of inefficiency, as its predictability is not out - weighted by liquidity restrictions.

The Effects of Monetary Policy on Real Estate Market: a SVAR Analysis
Stirba, Pavel ; Čech, František (advisor) ; Hlaváček, Michal (referee)
This thesis empirically investigates the effects of monetary policy instruments on the real estate market for the following countries: Germany, France, the Netherlands, Spain and the United Kingdom, using a Structural Vector Autoregression model (SVAR) with Choleski recursive identification. This was done from the three different aspects: interest rate, scale of credit, and output. The covered period lasts from the first quarter of 2005 and then varies, depending on the country. The Wu-Xia shadow rate was used as a proxy for the interest rate, households' debt was used as a proxy for scale of credit, and real GDP was used as a proxy for the output. As the output of the analysis, we used the impulse response functions (IRF) and forecast errors variance decomposition (FEVD). The results suggest that the Residential Property Prices (RPPI) in every country react positively to an output shock and negatively to interest rates (except Spain). The effect of household debt on RPPI and statistical significance of intervals depend on the country observed.

Car demand modelling in the Czech Republic
Rückl, Adam ; Pertold-Gebicka, Barbara (advisor) ; Čech, František (referee)
The main purpose of this thesis is to construct a model of passenger cars demand and estimate it using data on new car registrations from the Czech Republic. The constructed model takes into account factors affecting not only the demand, but also the supply, as both of these variables form a simultaneous equations system. In order to estimate the model consistently, the econometric theory of simultaneous equations model is presented. At first the basic notations are introduced, the inconsistency of ordinary least squares estimates is proved and consistent methods of estimation are described, notably the two stage least squares and the indirect least squares methods. Observation of the data suggests that new passenger cars registrations in the Czech Republic were influenced by a specific taxation policy, which up to April 2009 did not allow the value added tax deduction in case of passenger cars. A large proportion of passenger cars were therefore registered as light utility vehicles. This fact has to be taken into account when studying the passenger cars demand. Results of the estimation by the two stage least squares method showed that the demand for new passenger in the Czech Republic is elastic in price and income. Significant sensitivity of the demand was observed also with respect to used cars...

The Inflation-Output Variability Relationship in the CEE countries: A Bivariate GARCH Model
Kubovič, Jozef ; Čech, František (advisor) ; Červinka, Michal (referee)
This thesis examines the output-variability relationship and causal relationships among the inflation, the output growth and their uncertainties for the Central and Eastern European region during the period of time that covers the economic crisis of 2008. We apply the bivariate GARCH(1,1) model with the constant conditional correlation covariance matrix to obtain conditional variances that proxy the two uncertainties and use Granger causality test to determine the causal effects among four variables. We come up with a number of interesting results. First, we did not find statistical evidence neither for the inflation-output variability relationship nor for the Phillips curve. Second, we uncovered support for the positive causal effect of the inflation on its uncertainty and negative causal effect for the reverse direction. Additionally, we also found some support for the indirect negative causal effect of the inflation on the output growth. These results support the policy of low and stable inflation in the countries. Finally, we showed that crisis has a significant impact on the results, changing the behaviour of conditional variances and causal effects among the variables. Powered by TCPDF (www.tcpdf.org)

Return and volatility spillovers across financial markets in Central Europe
Ketzer, Jaroslav ; Baruník, Jozef (advisor) ; Čech, František (referee)
This diploma thesis is devoted to the linkages among stock, bond and foreign exchange markets in the Czech Republic, Austria, Germany and Poland during the period from the beginning of the year 2007 to the end of the year 2014. In order to complexly describe the interconnections among the markets, we utilized two kinds of spillover indices (from the generalized and structural VAR model), dynamic correlation coefficients obtained from the multivariate GARCH model and contemporaneous coefficients from the structural VAR model that was identified through heteroskedasticity in structural shocks. These methods enabled us to describe the linkages among the markets from different angles, to capture their time evolution and to obtain a notion about the transmission mechanism among these markets in Central Europe. The results, inter alia, indicate an intensifying interconnection among the markets during crisis periods, lowering impact of stock markets, increasing influence of bonds and a dominant role of German bonds and Austrian stocks. At the same time, we were able to capture the influence of the European sovereign debt crisis on the spillovers and on the intensity of linkages among the markets. We showed that the intensity of linkages among bond markets relented, probably as a result of higher emphasis on the...

Does trading strategy based on overreaction and stock-bond decoupling generate additional profits?
Bosák, Martin ; Čech, František (advisor) ; Baruník, Jozef (referee)
Studying whether new trading rules provide higher returns than the buy-and-hold strategy is relevant for both finance theory and the asset management field. In this thesis, we examine the profitability of the newly proposed trading strategy based on the concept of price overreaction on eight developed stock indices. In comparison to other studies, we extend a definition of price overreaction with an inclusion of a minimum volatility threshold. Based on the Ordinary Least Squares model, we find that a volatility condition significantly improves the predictability of return reversals after positive price overreaction. For comparison with the buy-and-hold, we use Hansen's Superior Predictive Ability test that corrects the data snooping bias. Despite better annualised returns during in-sample and out-of-sample periods, the results show that the proposed strategy is not superior to the buy-and-hold at any stock index due to heavy reliance on the predictions of the largest declines. Nevertheless, we confirm the effect of decoupling (flight to quality) that can positively affect our strategy, but only when we do not take into account transaction costs. In the end, we summarize behavioural concepts that lie behind our strategy as the overreaction and decoupling are mostly justified with cognitive biases.

The Current Account and Balance of Payments: Implications towards the Real Exchange Rate, GDP Growth, Asset Prices and Stability
Clarson, Daniel ; Čech, František (advisor) ; Baxa, Jaromír (referee)
The Current Account and Balance of Payments: Implications towards the Real Exchange Rate, GDP Growth, Asset Prices and Stability Abstract in English In the aftermath of the global financial crisis, large global imbalances among countries' current account have been cited as a possible cause. The real exchange rate emerges as a key policy tool among countries within the research literature and in practice to manage a country's Balance of Payments indicators, despite mixed evidence. In this master thesis, we will construct a vector error correction model for cointegrating relationships utilizing the Johansen's test, using time series data for the US, UK, and Australia for the period 1973-2018. We examined the relationships between the real exchange rate, the current account, the financial account, net reserves, the interest rate, and openness to trade as well as employing Granger Causality tests. In the US, we found relationships between net reserves and both the current account and the real exchange rate. In the UK, the interest rate and the real exchange rate have a cointegrating relationship. In both the UK and Australia, we found a cointegrating relationship with the real exchange rate and current account. We examine the various theoretical and practical approaches towards viewing the Balance of Payments...
