Analýza indexů akciových trhů a režimů na komoditních trzích
Kuchina, Elena ; Cahlík, Tomáš (advisor) ; Máša, Petr (referee) ; Lukáčik, Martin (referee)
The thesis focuses on the identification of the typical scenarios of the mutual relations among the stock markets considering different regimes on the commodity markets. For the identified scenarios the investment recommendations have been suggested. Considering different regimes the commodity markets go through and the mutual linkage among the stock markets during different situations on the commodity markets, six scenarios of the stock markets' mutual relations have been analyzed. It was shown that during most unstable period, when highly volatile regime prevails simultaneously on the energy, precious metals and non-energy commodity markets, the whole economy becomes to be more tied: the stock market indices demonstrate stronger interdependence, and as a consequence the benefits of diversification begin to fail. During the simultaneous presence of low volatility on all three analyzed commodity markets the agreement between occurrences of highly volatile state of most stock markets, besides the indices within the European region (DAX, CAC 40, IBEX 35), is rather weak. Similarly the correlation within regions and with other regions is weaker comparing with other situations on the commodity markets, so the standard investment strategy can be kept. It was also shown that the interdependence among the stock markets during the period of high volatility on the energy market differs depending on the source underlying the oil price shocks causing higher volatility. The regimes prevailing on the commodity and stock markets during different time periods have been detected by applying Hidden Markov Model methodology. To examine the similarity between the stock market indices in terms of highly volatile regimes' occurrences, Jaccard's similarity coefficient is employed. The correlation among the stock markets was computed by Spearman correlation coefficient. The final part of research is devoted to the model-based approach used to analyze the dependence of the movement direction of SSEC index on other stock market indices between two trading days during different situations on the commodity markets. The dependency analysis was performed by applying Stochastic Gradient Boosting methodology.
Econometric analysis of inflation in open economy
Rebrova, Yulia ; Formánek, Tomáš (advisor) ; Kuchina, Elena (referee)
This bachelor thesis is focused on an econometric analysis of the inflation in an open economy. The aim of this paper is to investigate factors which influence the price level. A priority is given to the analysis of Austrian and Czech economies and of their dependence on the dominant German economy. Different specifications of Phillips curve and Exchange Rate Pass-Through method are used to breakdown the inflation rate. Theoretical part of the thesis carefully summarizes already known facts about inflation and its measuring. Moreover, it includes a closer look at econometrical models which will be used in this paper. The models for each country are developed and compared in the last part of this thesis. Results show that economies of selected countries underline macroeconomic theory and the inflation rate can be expressed by Phillips curve whereas Exchange Rate Pass-Through models cannot explain the behavior of the price level well. This paper reveals the complexity of the topic.
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.
Econometric analysis of the economy in game World of Warcraft
Buchníčková, Michaela ; Kuchina, Elena (advisor) ; Formánek, Tomáš (referee)
This thesis analyses the impact of real exchange rate and the official exchange ratio of fiat currencies and in-game golds on the price level in the game World of Warcraft. The work also includes a brief summary of the mechanisms of the in-game economy. The analysis is based on cointegration test and Granger causality test. Individual estimations are model based on the VAR and VEC models theory. The conclusions of this study are made for specific randomly selected pairs of servers with different populations. These results are not easily generalized for the entire regions, but they offer insight into the possible factors affecting the price level in each virtual economy. The results show that the price level on the American server Aegwynn affects the exchange rates of fiat and game currencies as well as that game currency exchange rate in the European region is sensitive to changes in exchange rates of the euro and the yuan. All calculations in this work were implemented in Eviews 8 software.
Models of Analysis and Forecasting of the insolvency of Czech companies
Kuchina, Elena ; Hušek, Roman (advisor) ; Řičař, Michal (referee)
Different scenarios of the financial situation can take place before the company's bankruptcy. There may be long-term trends in the deteriorating financial situation that indicate the impending corporate bankruptcy, or the bankruptcy may occur unexpectedly, even though the company was ranked among prosperous business units. If the economic situation of the company followed the second scenario, when insolvency was quite predictable, static model, i.e. the model which does not take into account the dynamics of changes in the financial indicators, is a good option to capture the probability of bankruptcy. However, the situation becomes different when the financial indicators fail to show a positive trend throughout some years before the insolvency. In this case, the predictive accuracy of the static model could be increased by a dynamic model by taking into account the fact that the development of the financial indicators in the past periods may affect the company's financial health for the period under consideration.
The use game theory and real options valuation in investment decisions
Kuchina, Elena ; Dlouhý, Martin (advisor) ; Rada, Miroslav (referee)
This work demonstrates a new approach how to evaluate investment projects under uncertainty. This approach consists of the unification of real option valuation and game theory principles. The application of the theoretical foundation of this "option game" is shown on the illustrative example, that represents two-stage game. Analysis of this example compares the investment project's value in case when the R&D investment is not carried out with the case when this investment is made. In latter case there are two different possibilities whether the investment outcomes are proprietary or shared. The present work shows that in the evaluation of investment projects besides standard NPV there is flexibility value and the value of strategic effect; whereas these two components usually go against each other. Within the framework of the given illustrative example a breakdown of the investment project's value is demonstrated in different cases.
