Exchange Rate Forecasting: An Application with Model Averaging Techniques
Mida, Jaroslav ; Horváth, Roman (advisor) ; Bobková, Božena (referee)
The exchange rate forecasting has been an interesting topic for a long time. Beating the random walk model has been the goal of many researchers, who applied various techniques and used various datasets. We tried to beat it using bayesian model averaging technique, which pools a large amount of models and the final forecast is the average of forecasts of these models. We used quarterly data from 1980 to 2013 and attempted to predict the value of exchange rate return of five currency pairs. The novelty was the fact that none of these currency pairs included U.S. Dollar. The forecasting horizon was one, two, four and eight quarters. In addition to random walk, we also compared our results to historical average return model using several benchmarks, such as root mean squared error, mean absolute error or direction of change statistic. We found out that bayesian model averaging can not generally outperform random walk or historical average return, but in specific setting it can produce forecasts with low error and with high percentage of correctly predicted signs of change.

The Czech National Bank Communication and the Yield Curve
Karas, Pavel ; Horváth, Roman (advisor) ; Maršál, Aleš (referee)
This thesis analyzes the effect of the Czech National Bank's (CNB) communica- tion on the interest rate volatility (PRJBOR reference rate). Starting with the literature survey about the central bank communication in the world, I focus on the literature that concerns the CNB. To model the CNB's communication, I use the GARCH(l,1), EGARCH(l,1) and TARCH(l,1) models. I have created a unique data set containing the dummy variables for the CNB communication. The results are as follows: (a) the CNB's communication tends to decrease the volatility, (b) timing of the communication has a key role as the comments closer to the meeting have bigger calming effect, and that (c) there is no clear effect concerning the comments of the Bank Board members in the media. JEL Classification Keywords E43, E44, E52, E58 Czech National Bank, monetary policy signaling, central bank communication, the term structure of interest rates, GARCH analysis Author's email karasp@email.cz Supervisors's email roman. horvath@gmail.com

Estimating implicit inflation target of the ECB
Melioris, Libor ; Horváth, Roman (advisor) ; Geršl, Adam (referee)
Existing estimations of implicit inflation target are primarily based on the assumption of parameter stability over time horizon. This work relaxes this assumption and proposes alternative framework based on time-varying parameter model. We aim on behaviour of European Central Bank in order to compare its official proclamations of price stability levels with our implicit estimations. We will also examine how two pillar strategy of European Central Bank is practically used.

Examining the impact of reforms on economic growth: The case of transition economies
Zhupaj, Lorena ; Horváth, Roman (advisor) ; Benáček, Vladimír (referee)
This paper aims to investigate the impact of reforms on economic growth in a sample of transition economies of Central Eastern Europe, South Eastern Europe and Commonwealth of Independent States from 1989 until 2010. We employ a panel data methodology and run a Haussman test to distinguish between a fixed effect and a random effect model. In addition, we take into account the role of reform reversals and examine their contribution in the growth dynamics. Reform downgrades are very common since in some cases progress in reforms has been stalled or even reversed due to political instability, wars, economic crises, etc. We model the reforms downgrades following the previous work of Merlevede (2003) using a different methodology and extending our period of estimation. Furthermore, the relationship between other explanatory variables (i.e. initial conditions, fiscal balance) and growth is further explored in the empirical estimation.

Comparison of the inflation prediction approaches: Monetary growth vs. Output gap analysis
Kuliková, Veronika ; Horváth, Roman (advisor) ; Babin, Adrian (referee)
Inflation is one of the often used monetary indicators in conducting monetary policy. Even though money supply is an essential determinant of inflation, it is not used in inflation modeling. Currently, output gap is considered as most predicative variable. This thesis brings the empirical evidence on the hypothesis of money supply carrying more information on estimating inflation than the output gap. It is provided on the case of 16 developed European economies using Bayesian Model Averaging (BMA). BMA is a comprehensive approach that deals with the model uncertainty and thus solves the variable selection problem. The results of analysis confirmed that money supply includes more information of inflation than the output gap and thus should be used in inflation modeling. These outcomes are robust towards prior selection and high correlation of some variables.

Credit rating agencies and their impact on the bond markets of EU countries
Havlíček, Tomáš ; Horváth, Roman (advisor) ; Jánský, Ivo (referee)
This thesis analyses long and short-term perception of announcements issued by leading credit rating agencies (Fitch, Moody's and S&P) in sovereign bond markets. Using three empirical approaches we assess the nature of impact of CRAs on 10Y sovereign bond yields and 5Y CDS of 24 countries of EU between 2002 and 2012. We find significant response of sovereign bond yield and CDS spreads to downgrades and negative outlooks. Furthermore there is evidence of anticipative power of sovereign bond markets in foreseeing negative events implying CRAs lag the market. The spillover effect from credit rating announcements has been revealed between both EMU and non-EMU parts of EU implying the financial integration is not limited only to countries with common currency. Well performing economies outside EMU are resistant to contagion.

Financial Stress Transmission from Developed to Emerging Countries
Gavrilenco, Nicolae ; Horváth, Roman (advisor) ; Jakubík, Petr (referee)
Charles University in Prague Faculty of Social Sciences Institute of Economic Studies MASTER THESIS Financial Stress Transmission from Developed to Emerging Countries Author: Bc. Nicolae Gavrilenco Supervisor: doc. Roman Horvàth, Ph.D. Academic Year: 2012/2013 Abstract In this research we have analyzed the financial system as it is today, describing the implications financial innovation had and the impact of the recent financial crisis. We tried to understand the nature of the financial stress and its measures. In the context of world financial integration it was also necessary to have a review upon the financial stress transmission channels from developed to emerging countries, determining the linkages and their measures. We employed a structural VAR model to determine whether there is empirical proof of financial Stress transmission from developed to emerging countries and see if financial integration represents the decisive factor in financial stress transmission. Our results suggest that there is a significant impact of financial stress in developed countries on the output of emerging ones. However we can observe an increasing influence of country-specific factors in explaining the variation in the rest of the variable of our model. The results also indicate the level of international financial...

Evaluation of interest rates predictions: The case of Czech National Bank
Boček, Josef ; Horváth, Roman (advisor) ; Serdarevič, Goran (referee)
This research focuses mainly on the evaluation of interest rates predictions (predictions of 3M PRIBOR rate) published by Czech national bank. In the first part of the thesis reasons and potential central bank's benefits of the publishing of interest rate predictions are presented, based on the current academic literature. In the next chapters econometric and non-econometric evaluation of Czech national bank forecasts is provided. Furthermore, predictions from Czech Treasury, random walk process and my own autoregressive and vector autoregressive predictions were evaluated as well. It has been concluded that Czech national bank produces and publishes the most accurate based on non-econometric and econometric evaluation of all examined predictions. Moreover during the F-test evaluation procedure, the forecasts of Czech national bank proved themselves to be unbiased for the longest time horizon of all examined predictions.

Bank Liquidity Creation and Real Economy: VAR Analysis
Hálová, Klára ; Horváth, Roman (advisor) ; Kruchynenko, Ihor (referee)
In this thesis we examine the interactions of bank liquidity creation and real economy using vector autoregression model. We selected inflation, unemployment rate and interest rate as basic economic variables which theoretically could influence bank liquidity creation. We decided to examine the reverse relationship whether bank liquidity creation has a significant impact on real economy. We study these interactions using data from Czech Republic within ten-year period from 2000 to 2010. Our results suggest that macroeconomic fluctuations have a significant impact on bank liquidity creation. The results also support our reverse hypothesis that higher liquidity creation can improve macroeconomic conditions.

The determinants of access to finance: evidence for transition economies
Cazachevici, Alina ; Horváth, Roman (advisor) ; Benáček, Vladimír (referee)
Charles University in Prague Faculty of Social Sciences Institute of Economic Studies MASTER THESIS The determinants of access to finance. Evidence for transition economies Author: Alina Cazachevici Supervisor: Roman Horvath, Ph.D. Academic Year: 2012/2013 Abstract The thesis provides an empirical analysis of impact of country-level and firm-level determinants on access to finance in transition economies. Generalized Ordered Logit model is applied on survey data for transition countries, combined with financial market indicators. The results show that higher concentration in banking sector, as well as higher financial deepening have a positive impact on access to finance, while volatile macroeconomic environment, higher implication of foreign-owned and state- owned banks seems to be perceived as increasing obstacles in accessing external financing. Combining indexes for liberalization in banking sector and liberalization of securities markets proved that before liberalization process firms had better access to finance. One of the possible explanations is that before liberalization state banks were forced by politicians to issue more loans, while after reforms the political pressure was removed, imposing stricter conditions for loan granting. Inclusion of corruption variable yields expectable results that...
