Optimal Investment Portfolio with Respect to the Term Structure of the Risk-Return Tradeoff
Urban, Matěj ; Rippel, Milan (advisor) ; Červinka, Michal (referee)
My thesis will focus on optimal investment decisions, especially those that are planned for longer investment horizon. I will review the literature, showing that changes in investment opportunities can alter the risk-return tradeoff over time and that asset return predictability has an important effect on the variance and correlation structure of returns on bonds, stocks and T bills across investment horizons. The main attention will be given to pension funds, which are institutional investors with relatively long investment horizon. I will find the term structure of risk-return tradeoff in the empirical part of this paper. Later on I will add some variables into the model and investigate whether it can improve the results. Finally the optimal investment strategies will be constructed for various levels of risk tolerance and the results will be compared with strategies of Czech pension funds. I am going to use data from Thomson Reuters Datastream, Wharton Research Data Services and additionally from some other sources.

Phillips curve verification by time series analysis of Czech republic and Germany
Král, Ondřej ; Arltová, Markéta (advisor) ; Blatná, Dagmar (referee)
Government fiscal and monetary policy has long been based on the theory that was neither proven nor refuted since its origination. The original form of the Phillips curve has undergone significant modifications but its relevance remains questionable. This thesis examines the correlation between inflation and unemployment observed in the Czech Republic and Germany over the last twenty years. The validity of the theory is tested by advanced methods of time series analysis in the R environment. All the variables are gradually tested which results in the assessment of the correlation between the time series. The outcome of the testing is presented for both countries and a comparison at international level is drawn. Is is discovered that both of the countries have dependencies in their data. Czech republic has significant dependency in both ways, for Germany is the dependency significantly weaker and only in one way.

How is the Swiss economy coping with the CHF appreciation after the SNB's exít?
Borufka, Roman ; Holub, Tomáš (advisor) ; Hájek, Jan (referee)
The objective of this thesis is to describe the situation in the Swiss economy before the SNB discontinued the minimum exchange rate. Furthermore, the aim is to anal- yse the impact of the abandonment of the exchange rate floor on key macroeconomic indicators such as GDP, year-on-year changes in consumer and producer prices or unemployment rate. The interactions between CHF/EUR exchange rate and real GDP, CPI and 3-month LIBOR are examined using VAR model on quarterly data from 1999 to 2016. The results suggest that the CHF/EUR exchange rate appreci- ation has temporary dampening effects on GDP, CPI and 3-month LIBOR. These results are consistent with the developments in macroeconomic variables after the discontinuation of the minimum exchange rate. JEL Classification C5, E24, E31, E43, F31 Keywords exchange rate, gross domestic product, consumer price index, interest rate, vector autoregressive model Author's email borufka.r(at)seznam.cz Supervisor's email Tomas.Holub(at)cnb.cz

Forecasting Exchange Rates: A VAR Analysis
Mida, Jaroslav ; Horváth, Roman (advisor) ; Ivanková, Kristýna (referee)
This thesis aims to out-of-sample forecast the USD/EUR exchange rate using four macroeconomic variables, namely ination, interest rate, unemployment rate and industrial production index. The model applied is the vector autoregressive model. We use monthly data for a period of 2002-2011 and use the data from 2012 in order to compare the forecast accuracy with the random walk, which is believed to outperform many models when forecasting for a short-time horizon, such as one year. We found out that the vector autogressive model beat the random walk in the period of one and three months, which was surprising. In the longer horizon of six, nine and twelve months, random walk, as expected, heavily outperformed vector autogressive model. The reasoning behind this could be that there was no clear trend in the USD/EUR exchange rate during this period.

Econometric analysis of inflation in the Czech Republic
Demeš, Jiří ; Hušek, Roman (advisor) ; Pánková, Václava (referee)
The degree work is focused on analysis of inflation with help of suitable econometric models. Inflation with it's forms and possibilities of measuring is described at the beginning of the paper. There is mentioned an importance of monitoring and analysing inflation in view of Czech national bank. Consequently there are described characteristics of time series, which are important from viewpoint of construction of econometric models. Next part of this paper is focused on characterization of econometrics models. At first there is vector autoregression model, in this connection there is discussed the essence of Granger causality and impulse reaction. There are also noticed both error correction model and vector error correction model. The empirical part of degree work involves the use of these models on selected macroeconomic time series of the Czech republic. The objective is to analyze the relationship between inflation and other individual macroeconomic quantities. There is established the optimal vector autoregressive model and the results of Granger causality and impulse reaction are interpretated. Both error correction model and vector error correction model examining cointegration are also applied.
