Three essays in Development Economics
Valíčková, Petra ; Cahlík, Tomáš (advisor) ; Janda, Karel (referee) ; Ščasný, Milan (referee) ; Nicolas, Claire (referee)
This dissertation thesis touches on some important aspects of development, including financial development and improved access to reliable energy sources, regional integration and expanded opportunities for trade. This thesis was written to help guide policy reforms especially in developing countries to expand sources of growth and put countries on track to better meet their long-term development goals, including a better and more sustainable future for everyone. This dissertation consists of three papers. In the first paper I investigate the empirical evidence on the relationship between financial development and economic growth. In doing so, I assessed over 270 studies for their potential inclusion in a meta-analysis. From those studies that contained an empirical estimate of the finance growth relationship, I compiled 1,334 coefficients and coded study characteristics for each. Taking the reported estimates together, I find a positive link between financial development and economic growth, but with widely varying individual estimates. By applying a multi-variate meta-regression, I explain the variation in reported results, stemming not only from differences in research design (by authors addressing or ignoring potential endogeneity issues) but also from real drivers (different regional and time...

The Impact of Student Employment on Educational Outcomes: A Meta-Analysis
Kroupová, Kateřina ; Havránek, Tomáš (advisor) ; Schwarz, Jiří (referee)
Despite the extensive body of empirical research, the discussion on whether student employment impedes or improves educational outcomes has not been resolved. Using meta-analytic methods, we conduct a quantitative review of 861 effect estimates collected from 69 studies describing the relationship between student work experience and academic performance. After outlining the theo- retical mechanisms and methodological challenges of estimating the effect, we test whether publication bias permeates the literature concerning educational implications of student employment. We find that researchers report negative estimates more often than they should. However, this negative publication bias is not present in a subset of studies controlling for the endogeneity of student decision to take up employment. Furthermore, after correcting for the negative publication bias, we find that the student employment-education relationship is close to zero. Additionally, we examine heterogeneity of the estimates using Bayesian Model Averaging. Our analysis suggests that employment intensity and controlling for student permanent characteristics are the most important factors in explaining the heterogeneity. In particular, working long hours re- sults in systematically more negative effect estimates than not working at...

Essays in Applied Meta-Analysis
Polák, Petr ; Havránek, Tomáš (advisor) ; Pugh, Geoff (referee) ; Rusnák, Marek (referee) ; Reed, William Robert (referee)
The dissertation consists of three papers presenting applications of meta-analysis in economics and introductory chapter which discusses the development of meta-analysis in author's perspective as well as strengths and weaknesses of this quantitative method to synthesize empirical research. In the first paper analyses the impact of information and communication technology investments on productivity. The second paper focuses on the trade effect of the euro. In the third investigates the relation between international trade flows and trade costs.

Environmental quality related to economic growth: meta-analysis of environmental Kuznets curve hypothesis
Petříková, Viktorie
This diploma thesis examines scientific articles to determine if there is an agree-ment in literature on the topic of relationship between economic growth and en-vironment. This investigation uses meta-analysis to explore the systematic varia-tion across environmental Kuznets curve studies to better understand the specific factors that affect this relationship. Binomial and multinomial logit models are performed. Final results stimulate an ongoing discussion of not discovering any unity in this area.

Systematický přehled: Bullwhip efekt
Miková, Veronika
Miková V. Systematic review: Bullwhip effect. Diploma thesis. Brno: Mendel University, 2019. The diploma thesis is focused on the Bullwhip effect, also known as Forrester effect. The aim of this thesis is to provide a systematic review of the studies dealing with this effect in supply chain management. Part of this is the creation of a meta-analysis to identify and quantify the prevailing conclusions of selected studies and creation of a cluster analysis. Consequently, it is shown that authors identify four major causes of the effect, use moving average, minimum mean square error and exponential smoothing as methods for forecasting. Furthermore, in most cases they insufficiently describe examined sample. Information sharing, using information and communication technologies or number of echelons in supply chain are taken as major tools to reduce effect that help to optimize the supply chain.

Meta-analýza studií asymetrické transmise cen ropy u palivové produktové vertikály benzínu a nafty
Kostruchová, Klára
Kostruchová Klára. Meta-analysis of asymmetric transmission oil prices studies in the fuel product verticals of petrol and diesel. Bachelor thesis. Brno: Mendel University, 2018. The topic of this thesis is the meta-analysis of asymmetric price transmission between the price of oil and the prices of other petroleum products, also known as "rockets & feathers". The empirical analysis is based on binomial and multinomial logit classification models to evaluate the empirical evidence of the oil price asymmetry. In both cases, approximately 75 % of the values were correctly classified. An important finding is that significant regressions include methodological variables, namely frequency observation and estimates made on panel data. In general, studies with higher expected rates (ie panel studies and higher frequency studies) have less frequent asymmetric transmissions. In the case of fundamental variables, there is no significant evidence of their classification capability of the presence of asymmetry of price transmission.

Revealed preferences for outdoor recreation in natural areas - Czech and European perspective
Kaprová, Kateřina ; Melichar, Jan (advisor) ; Brůha, Jan (referee) ; Šauer, Petr (referee)
K. Kaprová (2019): Revealed preferences for outdoor recreation in natural areas - Czech and European perspective Abstract of the Doctoral Dissertation The dissertation thesis focuses on the investigation and synthesis of recreation welfare benefits associated with natural areas in the Czech Republic and in Europe. The dissertation thesis consists of five case studies. These represent various geographic levels of analysis: the level of one single recreation locality, the national level that takes into account large natural recreation sites in the Czech Republic (including protected areas), and a synthesis of results of studies on the European level. The methodological approach is based on the theory of environmental economics and employs non-market valuation techniques based on methods of revealed preferences, namely the hedonic pricing method and two types of travel cost modelling. In Study I, we examine how the presence and characteristics of urban greenery affect property prices in Prague. The results confirm that proximity to greenery and its area are important determinants of housing prices in Prague, which means that residents realize the positive values provided by urban greenery, including recreational ecosystem service. Benefits to residents differ with the type of greenery. Urban forests have the...

Essays in Empirical Financial Economics
Žigraiová, Diana ; Jakubík, Petr (advisor) ; Witzany, Jiří (referee) ; Teplý, Petr (referee) ; Gächter, Martin (referee)
This dissertation is composed of four essays that empirically investigate three topics in financial economics; financial stress and its leading indicators, the relationship between bank competition and financial stability, and the link between management board composition and bank risk. In the first essay we examine which variables have predictive power for financial stress in 25 OECD countries, using a recently constructed financial stress index. We find that panel models can hardly explain FSI dynamics. Although better results are achieved in country models, our findings suggest that financial stress is hard to predict out-of- sample despite the reasonably good in-sample performance of the models. The second essay develops an early warning framework for assessing systemic risks and predicting systemic events over two horizons of different length on a panel of 14 countries. We build a financial stress index to identify the starting dates of systemic financial crises and select crisis-leading indicators in a two-step approach; we find relevant prediction horizons for each indicator and employ Bayesian model averaging to identify the most useful predictors. We find superior performance of the long-horizon model for the Czech Republic. The theoretical literature gives conflicting predictions on how bank...

Income Inequality and Economic Growth: A Meta-Analysis
Posvyanskaya, Alexandra ; Havránková, Zuzana (advisor) ; Bauer, Michal (referee)
The impact of inequality on economic growth has become a topic of broad and current interest. Multiple researches investigated the issue but the disparity of opinions and empirical results is huge. The present thesis revises the pri- mary literature through a meta-analytical approach applying Bayesian Model Averaging (BMA) estimation technique. We examine 562 estimates collected from 58 studies published between 1991 and 2015. I find the evidence of the publication bias presence in the literature. The authors of primary studies tend to report preferentially negative and significant estimates. The BMA results suggest that the effect of inequality on growth is not straightforward and is likely not linear. A single pattern for inequality/growth relationship is not fea- sible since the results vary across used income inequality measures, estimation methods and data structure and quality.
