Hedonic models on real estate market
Špesová, Nikola ; Zouhar, Jan (advisor) ; Bíza Bisová, Sára (referee)
Thesis is concerned with the Prague apartment prices. It compiles various econometric models determine that price under linear regression. It discusses the influence of individual factors such as size, number of rooms, floor, type of ownership, and so on. It focuses on three main hypotheses. The first is the floor impacts, which is proving to have a quadratic functional dependence. The second is a comparison of personal property with a cooperative and brick and panel construction. It turned out that the price difference between brick privately ownership and cooperative panel construction can be up to nearly 30 %. The last major hypothesis is the impact of time perspective between 2006 and 2013. The data shows that the financial crisis of the years 2007 - 2009 hit the Prague real estate market only on a small scale.

The analysis of effect of body height on wages in Czech Republic
Frank, Daniel ; Bíza Bisová, Sára (advisor) ; Čermáková, Klára (referee)
The aim of this thesis is to analyze the effect of body height on wages of men and women in Czech Republic. I construct regression models using data gathered by survey in Prague and Zlin. Parameters of these models are estimated by using ordinary least squares method and also two-stage least squares method including instrumental variables. Because of large differences of locations I decided to examine mentioned cities separately. Research reveals the significance of the main explanatory variable only at model studying Zlin utilizing ordinary least squares method. An increase in human height by a centimeter is associated with a growth of his/her wage by 0.65 % on average.

Analysis of determinants of demand for counterfeits
Novák, Martin ; Bisová, Sára (advisor) ; Slaný, Martin (referee)
The theoretical part of thesis describes the theory of counterfeits and review of foreign literature. The empirical part analyzes the factors that influence the demand for counterfeits. Data for analysis are obtained by using questionnaires for two cities - Dvůr Králové nad Labem and Prague. Main determinants of demand for counterfeits are experience with counterfeits, satisfaction with them, price of counterfeits and current income. Analysis has shown, that these determinants could be applied to both cities and they are significant in almost all of the models. We can also observe a few other minor determinants that influence the demand for counterfeits.

An Econometric Approach to Efficiency Analysis
Chylíková, Alena ; Pánková, Václava (advisor) ; Bisová, Sára (referee)
This diploma thesis deals with the stochastic frontier approach -- a tool for the analysis of technical efficiency. First, general outline, basic terms and approaches to efficiency analysis are overviewed. Also the theoretical background of production functions is involved, focused on the Cobb-Douglas production function. Furthermore, the frontier approach and the stochastic frontier approach for cross-sections data is covered. Based on this, stochastic frontier model with time-varying technical efficiency for panel data is introduced with respect to maximum likelihood estimation. The second part offers an application of the model to assess technical efficiency of ice hockey teams in the NHL for the 1997-2013 period. Output of the production is measured by the winning percentage, inputs are salaries of three categories -- goaltender, defenseman and centers/wingers.

The Analysis of How the Education Achieved by Parents Influences the Lenght of Their Children's Studies
Dočekalová, Veronika ; Bíza Bisová, Sára (advisor) ; Brožová, Dagmar (referee)
The thesis analysis how the education achieved by parents affects the education achieved by their children. The least square method is used for the regression analysis. All the estimations are based on the survey-acquired data from Prague and Pilsen. Alongside the estimations for these two cities alone, the influence in all dataset is examined as well. The cross-sectional data were acquired throughout the first quarter of 2014. The certain influence of both mother's and father's education on the education of their descendants was demonstrated by the analysis. Other significant factors influencing acquired education turned out to be for instance a number of siblings or divorce in a family.

The analysis of the cyclically adjusted budget balance
Mareš, Michal ; Bisová, Sára (advisor) ; Kadeřábková, Božena (referee)
The thesis analyzes the cyclically adjusted budget balance on the data of the Czech Republic between 2004 and 2014. There is a big demand to consolidate public finances and the aim of this study is to assess whether this appropriate indicator is convenient to achieve the fiscal responsibility of individual countries. At first, the CAB is estimated by using the method of the European Commission, it is called a production approach on the basis of Article Denis, Morrow, Roger (2002). The work is also based on the article written by Bezděk, Dyczak , Krejdl (2003), which compares the OECD method with the ESCB method. Afterwards the calculation is performed by a modified procedure, using the Hodrick-Prescott filter instead of the production function to estimate potential output. The analysis shows the complexity of the estimation of the parameter which is given by great demands on the input data and arbitrariness. The CAB is discussed not only methodologically but also in its practical use in the context of the economic situation in Europe.

Evaluation of effectiveness of renewable energy sources
Vrobel, Marcel ; Sekničková, Jana (advisor) ; Bíza Bisová, Sára (referee)
The problem of comparing different sectors, companies, or projects occurs very often. This problem arises of poorly chosen metodics or requirements for results. The results of such comparisons are inconclusive and then useless. The contribution of this work is a practical guide which focuses on using of data envelopment models for evaluation of different options. In this thesis DEA models are presented on renewable energy sources. For proper understanding of the problems it is necessary to define what the data envelopment models (also known as DEA models) are. The purpose of this thesis is to inform about their creation and origins and also the description of their function. There is also an introduction into the teory of renewable energy sources. Renewable energy sources are evaluated based on their input. In this thesis is a comparison of biomass with solar, water and wind energy.

Graphical models in statistics and econometrics
Hubálek, Ondřej ; Zouhar, Jan (advisor) ; Bisová, Sára (referee)
Graphical models in statistics and econometrics provide capability to describe causal relations using causal graph in classical regression analysis and others econometric tools. Goal of this thesis is description of causal modelling of time series with help of structural models of vector autoregression. There is description of procedure of building structural VAR model, principle of graphical models and building model for causal dependence analysis. For purpose of comparison there are used data from both USA and Czech Republic and comparison of similar models for both countries is presented. Best models are then selected, to show causal relations between macroeconomic variables. For purpose of analysis, impulse-response functions are used to show impact of demand shock on GDP and other macro indicators.

Human capital and willingness to invest in education
Kras, Jakub ; Bisová, Sára (advisor) ; Brožová, Dagmar (referee)
The theoretical part of the thesis describes the theory of human capital and education investments. The empirical analysis follows up the factors which influence the decision of the High school students in Teplice and Prague -- whether to study at university or not. The analysis is based on data, obtained by questionnaire survey, made in four types of high schools: the grammar school, the secondary technical school, the secondary health school and business academy. The main factors include the type of the secondary schools, the income of parents, study expenses, expected future salary and the income of parents, study expenses, expected future salary and the education of parents. The analysis has proven, that the students from Prague want to attend the university more than the students from Teplice. Significant factors for students from Teplice are the type of the high school, study expenses, the education of father while for the students from Prague are among the others important factors connected with the future salary and the education of mother.
