The Causal Effect of Parents' Schooling on Children's Schooling: A Meta-Analysis
Pokorná, Anastasia ; Havránková, Zuzana (advisor) ; Kukačka, Jiří (referee)
One of the topics concerning education's improvement is the intergenerational transmission of education. The main goal of our study is to analyse the causal efect of parents' education on children's education. We collect 387 estimates of the causal efects from 23 studies. Using our dataset and meta-analytic methods, we test for the presence of publication bias in the literature and try to explain the heterogeneity in the results of the primary studies. After correction for publication bias, the mean becomes smaller than the mean reported in the literature and varies from 0.044 to 0.185. For exploring the heterogeneity of the estimates we use Bayesian Model Averaging and Frequentist Model Averaging. Our results suggest that there is a country heterogeneity in the estimates of the causal efect. Moreover, controlling for the size of a household in the original regression is important for the explanation of the diferences in the results of the primary studies. In addition to it, we collect 605 estimates of the non- causal associations from 39 studies and analyse the publication bias and the heterogeneity of results also using this sample. 1

Socioeconomic predictors of alcohol consumption patterns in the Czech adult population
Hanzal, Jan ; Havránková, Zuzana (advisor) ; Votápková, Jana (referee)
This empirical study focuses on the relation between individual social and economic variables and patterns of alcohol consumption in the Czech Republic. The work is divided into two parts. The first one concentrates on an exploratory analysis of a cross-sectional dataset. The results of this part reveal that several variables are significantly correlated with alcohol consumption, namely education, marital status and household income. The second part attempts to get closer to the actual causal effects of unemployment and household income on alcohol consumption by employing the Arellano- Bond estimator on a separate panel dataset. The results somewhat differ from the first part, with household income having a noticeably higher point estimate. The aim of this thesis is to bring more current and, most importantly, more robust results to the research on the topic.

Bank profitability in Mongolia
Chuluunbaatar, Tumenjargal ; Pečená, Magda (advisor) ; Havránková, Zuzana (referee)
One should judge the performance of banks in developing countries on a different background that is uniformly applied for developed countries. Methods of evaluating bank performances such as Economies Value Added (EVA) or Method of Comparables are of little help as they heavily rely on the stock price of banks on exchange market which is often unavailable for most banks. And when it is available it is hard to assure the "fair market value" given the underdeveloped capital market. Therefore traditional accounting measurements for bank profitability, namely Return on Asset and Return on Equity are natural candidates and are used for assessing the performance of Mongolian banks. Based on the respective analysis, a hypothesis that a bank size is an important factor for higher profitability is tested for a sample of banks which subsequently leads to a conclusion that bank size effect on profitability is rather insignificant.

Meta-Analysis in Economics: Application to Measuring the Euro's Trade Effect
Polák, Petr ; Havránek, Tomáš (advisor) ; Havránková, Zuzana (referee)
Meta-analysis is a very strong and effective tool designed for the synthesis of results of empirical research. It provides a possibility to make reliable conclusions and offers more systematic and unbiased view at empirical studies than do narrative reviews. This thesis begins with description of meta-analysis from the theoretical point of view and, therefore, is the first Czech-written methodology of modern meta-analysis suitable for economics. This part is followed by an applied meta-analysis that investigates the euro effect on common trade exchange, and the analysis is focused on publication bias and the use of the multilevel random effects model. The empirical part is based on 2580 estimates gathered from 33 studies that investigate the relationship between euro and trade volume. The meta-analysis reveals the presence of publication bias, confirms the economic research cycle hypothesis and estimates, according to the available literature, that the true Rose effect lies probably between 2 and 6 percent.

The globalisation of the Chinese financial sector
Reyisha, Ahemaitijiang ; Teplý, Petr (advisor) ; Havránková, Zuzana (referee)
In this thesis we have studied China's financial sector globalisation by analysing the determinants of Chinese banking sector profitability, and the relationship between GDP growth and FDI inflows. For estimating the Chinese banking sector profitability, we applied system GMM estimation on the annual data of 56 banks currently in China. The time period of the data is from 2002-2011. We found out that both internal and external factors have impact on the Chinese banking sector profitability. As we have expected financial sector globalisation has positive impact on the profitability of banking industry. For analysing the impacts of financial sector globalisation in terms of FDI contribution to the Chinese economy, we have tested the relationship between FDI and GDP by running the VAR model on the macro data over the time period of 1987-2011. We have found that GDP growth explains the rapid development of FDI, and FDI indirectly influences the GDP growth by influencing the domestic investments.

The Elasticity of Substitution between Skilled and Unskilled Labor: A Meta-Analysis
Laslopová, Ľubica ; Havránková, Zuzana (advisor) ; Komárek, Luboš (referee)
In this thesis we use meta-analytic methods to quantitatively summarize empirical evidence on elasticity of substitution between skilled and unskilled labor. Review is based on sample of 684 estimates from 78 studies. After a brief overview of theoretical framework, estimation strategies and distri- bution of the existing estimates, we test for publication bias. According to regression-based tests for publication bias, we do not reject null hypothesis of no publication bias in the existing literature. To explain heterogeneity between the estimates, we use Bayesian Model Averaging. We find that both real factors and research design influence resulting value of estimated elasticity. Our synthetic estimates of the elasticity imply that skilled and unskilled workers are imperfect substitutes in the long run, substitutability in the short-run is mostly limited. JEL Classification: J82, J23, J24, J31 Keywords: elasticity of substitution between skilled and un- skilled labor, meta-analysis, publication bias Author's e-mail llaslopova@gmail.com Supervisor's e-mail zuzana.havrankova@fsv.cuni.cz 1

The Impact of Incentives on Electric Vehicle Sales in the European Union
Tláskalová, Andrea ; Polák, Petr (advisor) ; Havránková, Zuzana (referee)
This thesis provides a comprehensive analysis of electric vehicle incentives and investigates their impact on the uptake of electric vehicles within and beyond the European Union over the period of 2010 to 2019. Depending on the kind of benefit they provide and their timing, the incentives are divided into one-time monetary, recurring monetary, and non-monetary incentives. To properly evaluate the effect of incentives, a fixed effects and difference-in-differences methods are employed, allowing us to control for unobserved factors affecting the electric vehicle market. A fixed effects analysis revealed a significant positive effect of one-time monetary incentives on battery electric vehicle sales, and a significant positive effect of both one-time and recurring monetary incentives on plug-in hybrid electric vehicle sales. Additionally, when considering the effect of individual incentives, the most important ones were found to be rebate and point-of-sale tax incentive. A difference-in-differences analysis confirmed a statistically significant effect of rebate on the sale of battery electric vehicles.

Socio-Demographic determinants of traffic accidents in the Czech Republic
Stejskal, Jakub ; Kalabiška, Roman (advisor) ; Havránková, Zuzana (referee)
This thesis aims to analyze variables influencing different aspects of traffic accidents in the Czech Republic, such as frequency or fatality. Traffic accidents are a huge issue as there are 100 000 of them in the Czech Republic every year alone. The main contribution of this thesis is a new approach looking only at specific types of traffic accidents, such as those caused by speeding, introducing new variables that might be related to traffic accidents, and replicating the results of existing research in the area of the Czech Republic. On the one hand, we found a negative correlation between the portion of wedded people in the area and the number of traffic accidents. On the other hand a positive correlation between portion of wedded people and the number of people killed per accident. One possible explanation for this is that wedded people drive safer, but on average, there are more people in their car, resulting in more deaths in case of traffic accidents. 1
