Does campaign spending have any impact on election outcome ?
Dušek, Ondřej ; Hronza, Martin (advisor) ; Kovanda, Lukáš (referee)
This Thesis analyzes the impact of campaign spending of political parties on election outcome. The Thesis uses data from the Parliamentary library of the Chamber of Deputies of the Czech republic, annual reports of political parties and from the Czech Statistical Office. For the first estimation, a method of Ordinary Least Square is used, consequently the equation of the model is edited using instrumental variables, in order to eliminate endogeneity. A new regression is estimated using Two-Stage Least Squares method. After the editing, all the explanatory variables are corelated and insignificant, although, the model itself works. In the end, this work did not succeed in measuring a predicted positive impact of campaign spending on election outcome. This "non-result result" shows the importance of an extensive dataset, which would allow an alternative approach to modelling and eliminating strong multicollinearity in the model.

Analysis of the influence of the quality of life on suicide rate
Kolářová, Michaela ; Hronza, Martin (advisor) ; Babin, Jan (referee)
This thesis analyzes the impact of various affecting the quality of life on the suicide rate in the individual regions of Czech Republic in 2000 -- 2008 and answers the question, whether we can find happiness -- suicide paradox. The research is based on data from the Czech Statistical Office I estimate the econometric model. As determinants of the endogenous variable (suicide rate) I present variables of the index of the quality of life. The results do not show a clear impact of index of quality of life on the suicide rate as a whole. Some of variables confirm the hypothesis about the existence of happiness -- suicide paradox, on the contrary other variables disprove this paradox. The hypothesis about the existence of happiness -- suicide paradox based on these data can not be conclusively confirm or disprove. It appears that during this period the total number of committed suicides is decreasing.

Is Slevomat.cz an effective marketing instrument?
Slavík, Lukáš ; Hronza, Martin (advisor) ; Čermáková, Klára (referee)
Some firms, specifically 19,42 %, are reaching a loss after the promotion on the group buying site Slevomat.cz. A possible explanation is unsuitability of Slevomat.cz as a marketing instrument for all types of traders. A crucial factor for business profit is, in many cases, another purchase made by customers for the undiscounted price. The results suggest that on the return of customers to another purchase have a positive effect size of the company, offered type of goods/services, employee satisfaction and the number of newly acquired customers through promotion. An important determinant of customers return has proven to be the profit made by cooperation with Slevomat.cz and the relative discount rate. Contrary the number of sold vouchers has no impact on return of customers. Thus for the advertising company is helpful to set the optimal combination of discount rate and the maximum number of offered coupons.

Effect of changes in selected tax atcs on economic status of the state
Vildová, Iveta ; Hronza, Martin (advisor) ; Rod, Aleš (referee)
This thesis verifies the positive impact of income law changes on economy due to relative reduction of statutory income tax rate during last years and negative impact growing statutory value added tax rate. The theoretical part presents studies that comment on the tax burden and economic state of the country. In practical part is performed the regression analysis on the data by 2012 obtained mainly from Czech Statistical Office and legal systems ASPI and Codexis. Basic statutory rates of corporate and value-added taxes are significant with negative effect on GDP. Finally, the work confirms the results of other studies regarding the influence of these taxes on economic state of the country.

The Empirical Analysis of Efficiency of Wagering Market
Flegr, Jan ; Hronza, Martin (advisor) ; Koubek, Ivo (referee)
Aim of this diploma thesis is to provide empirical tests of market efficiency of tennis wagering market. In large dataset, which consists of nearly 47 thousands matches and 225 thousands odds, I am searching for anomalies, which can prove market inefficiency. Potentially profitable and exploitable betting strategies are also examined. Main tools of empirical analysis are linear probability models and logit models. Favorit-longshot bias is present in my data, this finding is consistent with results of other empirical works (Lahvička, 2013; Cain, Law, Peel, 2000). Major contribution of this paper is confirmation of home-away bias, the issue, which was not tested in tennis matches so far. The same holds for chart-bias. I am not able to find profitable wagering rules based on out-of-sample predictions of my models. Simple betting rule, which consists of betting systematically on overwhelming favorites, is derived from historical odds. This strategy yields a profit 0,0094, but it's applicability is very limited.

Do players in NHL play better in their contract year season?
Weber, Vít ; Hronza, Martin (advisor) ; Babin, Jan (referee)
This bachelor thesis examines wheather or not the attackers in NHL occurs strategic behavior called shirking. To verification the thesis anylizes the efekt of contract year to points per game in the competition. The data are obtained for seasons 2010-2011, 2011-2012 and 2012-2013. Effect of the depandence of contract year to player points per game is captured by the independent dummy variable CON. The estimation method ordinary least squares is used. After detecting presence of heteroskedasticity model is estimates with method of heteroscedasticity corrected standart errors. The coeficient results indicates that the attackers in NHL increase their points per game for 0,02 in contract year ceteris paribus.

Is subsidizing renewable energy sources effective?
Makovec, Petr ; Hronza, Martin (advisor) ; Babin, Jan (referee)
This paper examines the current situation of renewable energy sources. Using various models, the paper shows the relationship between the usage of renewables and the total amount of greenhouse gas emissions. Based on the data from EU, models show that using renewables helps to lower damage of the enviroment. Additionally, this paper includes calculation of estimated costs of lowering emissions in the Czech Republic. According to the results, lowering greenhouse gas emissions by one ton of carbon dioxide costs 150-250 euro.

Are Czechs superstitious or the effect of Friday the 13th in accidents on Czech highways
Koucká, Lucie ; Hronza, Martin (advisor) ; Rod, Aleš (referee)
The aim of this thesis is to find out whether Friday the thirteenth as a chosen representative of the superstition has an influence to the number of traffic accidents in the Czech Republic. The hypothesis that is being verified is that on Friday the thirteenth, drivers will be more cautious resulting in less accidents. Based on the five year long time series the model is estimated using the ordinary least squares with robust standard errors where the endogenous variable is daily number of car accidents. The exogenous variables are Friday the thirteenth, the public holidays, the precipitation, the average daily temperatures and the gas prices. The "Friday the thirteenth" variable turned out as statistically non-significant. Based on the results of the econometric analysis we can reject the hypothesis of this thesis. This conclusion was further confirmed by the results of the survey conducted.

Prediction of student performance at Faculty of Economics, University of Economics
Adamcová, Lucie ; Hronza, Martin (advisor) ; Babin, Jan (referee)
The main task of this thesis is to test the quality of Scio's General Academic Prerequisites (OSP) test as entrance exam to Faculty of Economics, University of Economics. Besides that the thesis finds and tests other determinants and predictors of students' success on the faculty. The main hypothesis states: the relationship of results of OSP with success of student on faculty is positive eventually nonexistent and so it does not fulfill the criterion of high-quality entrance exam. The thesis assumes inefficiency of public school system thanks to absence of market signals. The thesis refutes this hypothesis based on regression and correlation analysis of sample of 225 students of the faculty. Using this dataset the thesis tests various variables and their prediction ability of students' success. Maturity's exam proved to be the best of those variables.
