Moravcová, Michala ; Horváth, Roman (advisor) ; Komárek, Luboš (referee) ; Baumohl, Eduard (referee) ; Pappas, Vasileios (referee)
This dissertation thesis consists of three essays on new EU foreign exchange markets (FX), i.e. the Czech koruna, Polish zloty and Hungarian forint. In the first two essays, the impact of foreign macroeconomic news announcements and central banks' monetary policy settings on the value and volatility of examined exchange rates is analyzed. In the third chapter, the conditional comovements and volatility spillovers on new EU FX markets is examined. The aim of this thesis is to contribute to the existing empirical literature by providing new evidence of the examined currencies during periods, which have not been examined yet (after the Global financial crisis (GFC), during the EU debt crisis and during currency interventions in the Czech Republic). The first essay (Chapter 2) examines the impact of Eurozone/Germany and US macroeconomic news announcements and monetary policy settings of the ECB and the Fed on the value of new EU member states' currencies. It is a complex analysis of 1-minute intraday dataset performed by event study methodology (ESM). We observe different reactions of exchange rates in pair with the US dollar on the US macroeconomic announcements and Euro-expressed FX rates on Germany macro news during the EU debt crisis and after it. We also provide evidence of leaking news, showing...

The Impact of Macroeconomic News on the Price of Financial Assets
Říha, Jakub ; Moravcová, Michala (advisor) ; Džmuráňová, Hana (referee)
This thesis investigates the effect of Czech macroeconomic news announcements and Czech National Bank (CNB) communication on the price of financial assets and its volatility. As the financial assets we selected the EUR/CZK and USD/CZK exchange rates and also the Prague stock PX Index. To analyze the aforesaid effect we employed the GARCH (1,1) and EGARCH (1,1) models, each with Normal and Student's t error distribution. The main results were that the CNB's communication indeed have significant effect on the price of all three examined assets and surprisingly also tend to increase their volatility. Also the macroeconomic announcements significantly influence examined assets however significant macroeconomic indicators differ for each asset. The most influencing ones are: CPI, 1YPRIBOR and the unemployment rate. Another finding of our research was that volatility of examined time series data shows the characteristics of leverage effect, volatility clustering and persistence. Powered by TCPDF (www.tcpdf.org)

Macroeconomic News and Their Impact on Sovereign Credit Risk Premia
Pištora, Vojtěch ; Hausenblas, Václav (advisor) ; Bobková, Božena (referee)
This thesis provides evidence of how macroeconomic surprises, constructed as deviations from market expectations, impact daily spread changes of Czech, Polish and Hungarian (CEEC-3) government bonds and sovereign credit default swaps. Firstly, we carried out series of event studies that inspect the spreads' reactions to the announcements. Subsequently, we employed the general-to-specific modeling approach and arrived at thirty GARCH-type models that consider surprises' impact on both conditional mean and variance. We have found significant impacts on the mean, yet in terms of magnitude, the impact of macroeconomic surprises has not been superior to that of broad financial factors. The impact on spreads' volatility appears more consequential though it lacks a clear pattern: Both good and bad news have been found to affect the volatility in either direction. Our findings suggest that with respect to macroeconomic news, daily changes of the bond spreads are driven rather by inflation expectations than by credit risk considerations. Foreign news proxied by the German surprises seems to affect the CEEC-3 bond spreads mainly through the risk-free proxy - the German Bund yield. Contrary to studies using low-frequency macroeconomic data, we have found no evidence for the "wake-up call" hypothesis.
