Range-based volatility estimation and forecasting
Benčík, Daniel ; Baruník, Jozef (advisor) ; Krištoufek, Ladislav (referee)
In this thesis, we analyze new possibilities in predicting daily ranges, i.e. the differences between daily high and low prices. The main focus of our work lies in investigating how models commonly used for daily ranges modeling can be enhanced to provide better forecasts. In this respect, we explore the added benefit of using more efficient volatility measures as predictors of daily ranges. Volatility measures considered in this work include realized measures of variance (realized range, realized variance) and range-based volatility measures (Parkinson, Garman & Klass, Rogers & Satchell, etc). As a subtask, we empirically assess efficiency gains in volatility estimation when using range-based estimators as opposed to simple daily ranges. As another venue of research in this work, we analyze the added benefit of slicing the trading day into different sessions based on trading activity (e.g. Asian, European and American session). In this setting we analyze whether whole-day volatility measures reliably aggregate information coming from all trading sessions. We are led by intuition that different sessions exhibit significantly different characteristics due to different order book thicknesses and trading activity in general. Thus these sessions are expected to provide valuable information concealed in...

Fiscal Rules in the European Union
Výprachtická, Terezie ; Šmídková, Kateřina (advisor) ; Schneider, Ondřej (referee)
ABSTRACTS PART I - The EMU and its Fiscal Rules This paper treats the fiscal rules of the European Economic and Monetary Union. It begins by introducing this union's inception and by discussing its set of fiscal rules - the Stability and Growth Pact, including its reform. The rationale for policy coordination and the need for fiscal rules in a monetary union are then investigated. The Stability and Growth Pact is then assessed from this point of view. The most important part of the paper is devoted to the analysis of whether the Stability and Growth Pact could be substituted by the disciplining effect of the financial markets. Our findings suggest that there is certain interaction between the financial markets and the governments' decisions on the fiscal policies and that this reaction has become stronger after the beginning of the latest financial and economic crisis. However, the institutional setup and market conditions in the European Union are such that this interaction is biased and thus we conclude that the Union needs to have fiscal rules. JEL Classification: C23, E44, E61, E62, H62, H87 Keywords: European Economic and Monetary Union, Stability and Growth Pact, Financial markets, Fiscal rules, Policy coordination PART II - The Golden Rule of Public Finance and Productivity of Public Capital This...

Analysis of the relationship between inflation rate, exchange rate, unemployment rate and repo rate
Denisova, Evgeniya ; Kuchina, Elena (advisor) ; Čížek, Ondřej (referee)
In this thesis is made analysis of the relations between inflation rate, unemployment rate, exchange rate and repo rate based on quarterly time series for the Czech Republic from year 2002 till year 2015. In the first part is explained the basic economic theory of inflation rate, unemployment rate, exchange rate and repo rate. The second part is focused on the theory of econometric time series, their models and tests, according to which the analysis is carried out in the practical part. As a preliminary step is compiled VAR model and determined the maximum lag length. After verifying the characteristics of random elements is estimated cointegration relationship. Subsequently, is assembled VEC model and based on statistically significant estimates of the variables are described long and short relations between economical variables.

Interconnection between labor market and monetary policy: NAIRU, unemployment hysteresis and monetary policy responses
Slaný, Martin ; Tomšík, Vladimír (advisor) ; Mandel, Martin (referee) ; Žák, Milan (referee)
This dissertation thesis deals with relation between labour market and monetary policy referring to two fundamental theoretical concepts -- natural rate hypothesis (or NAIRU) and unemployment hysteresis hypothesis. The first chapter outlines the most frequent values of the Phillips curve, the fundamental model of macroeconomics theory in the relation between the labour market and the monetary policy. The following chapter deals with the exogenous NAIRU concept which works as natural unemployment rate approximation. The unemployment hysteresis deals with the NAIRU as endogenous variable which is dependent on preceding imbalanced situations on labour market. The thesis outlines the main causes of the hysteresis: capital scrapping effect, role of the long-term unemployment and the insider-outsider hypothesis. The third chapter also comprises simple econometric tests of both particular mechanisms and the hysteresis itself based on usual unit roots tests. The results show the hysteresis using data from both the Czech Republic and Central and Eastern Europe countries (CEEC). The fourth chapter deals with monetary-political implications of the unemployment hysteresis. The practical part of the thesis is based on two hypotheses of the relation between inflation (policy interest rate) and NAIRU. The last chapter based on the VAR model outlines short-term relations between the labour market and monetary policy variables. Long-term relations are tested by both the co-integration analysis and vector error correction model (VECM). These models are examined on the data from the Czech Republic and Poland (2000-2013). The thesis also applies pooled regression estimate for ten CEEC. The results show that the monetary policy does have impact on the labour market not only in the short-term but also in the long-term period and thus they confirm the hysteresis hypothesis

Capital Market Integration. Evaluation and measurement: Risk-premium test
Víťazka, Peter ; Klosová, Anna (advisor)
The paper focuses on capital market integration at sovereign bond market in eleven selected euro zone countries (Austria, Belgium, Finland, France, Germany, Greece, Ireland, Italy, Netherlands, Portugal, and Spain). The first main objective is to test the degree of capital market integration before and after the crisis using Germany as a benchmark country and also among them as well. Secondly it evaluates and provides reasons of capital integration in time. The examination is applied through i) sigma convergence ii) yield spreads iii) correlation matrix iv) cointegration tests. I found almost zero yield differences before crisis. After 2008 results show segmentation in euro zone countries with certain special characteristic for countries with high credit ratings.

Inflation analysis and its comparison in the Czech Republic and Germany
Maxa, Jan ; Hušek, Roman (advisor) ; Formánek, Tomáš (referee)
The aim of this paper is to analyse and compare inflation and its dynamics between two countries -- the Czech Republic and Germany -- applying a special kind of econometric models. The first part of this paper is dedicated to economic theory of inflation -- fundamental terms, measuring methods and its targeting. The monetary policy in the Czech Republic and Germany is also shortly introduced. Next chapter tries to describe the econometric concept which is used in this paper -- vector autoregression model (VAR model). In connection with the VAR models, Granger causality, impulse response function, cointegration and error correction model are mentioned as well. The empirical part includes application of selected models on real time series of macroeconomic indicators. Next to the interpretation of results, the forecasts are also implemented.

Convergence analysis of selected financial indicators for CR and EU
Verner, Jan ; Pánková, Václava (advisor) ; Čížek, Ondřej (referee)
This thesis deals with the nominal and real convergence for Czech Republic and the Euro zone. It also includes analysis of synchronization of economic development in Czech and European economies for identifying potential risks associated with introducing the euro in the CR. The thesis describes different types of convergence and the relevant indicators with their historical evolution and hypothesis about future trends. The empirical part of the paper analyzes some selected indicators using econometric VAR models and linear and non-linear models of conditional heteroskedasticity. A suitable model for the analyzed data is chosen which gives a comparison of development in the Czech Republic and the EU. Especially time series causality, the existence of cointegration and conditional variance processes are observed. In conclusion there's a summary of all theoretical and modelled outputs with the risk evaluation of joining the monetary union.

Models of inflation and its volatility in CZ
Bisová, Sára ; Hušek, Roman (advisor) ; Pelikán, Jan (referee)
This paper focuses on analysing and modelling inflation and its dynamics in Czech Republic applying a special kind of econometric models. Firstly economic theory of inflation is mentioned - fundamental terms, measuring methods of inflation, the way Czech national bank is monitoring the inflation and obviously a short summary of historical evolution of inflation in Czech economy. In the second part of this paper two econometric concepts of modelling time series are introduced - vector autoregression models (VAR models) and volatility models, concretely ARCH and GARCH models. In connection with the VAR models, Granger causality, impulse response functions, cointegration and error correction models are described. The empirical part includes application of selected models on real time series of chosen macroeconomic indicators. The estimation outputs are interpreted and forecasts are implemented. The quality of chosen econometric models for modelling inflation in Czech Republic is discussed.

Modelování měnového kursu – parity a česká koruna
Mäsiarová, Jana ; Pánková, Václava (advisor) ; Havrlant, David (referee)
The paper analyses validity of main exchange rate theories in case of the Czech crown. Investigated relationships comprise purchasing power parity, interest rate parity and real interest monetary model. Technical part of the analysis involves cointegration, namely Johansen's method based on vector autoregressive models. Two currency pairs are in the focus: CZK/EUR and CZK/USD. Empirical calculations did not prove the absolute validity of the theories but pointed out to other factors of exchange rate, such as convergence process, impacts on inflation targeting decisions, non-monetarist determinants and the recent financial crisis.
