Innovation Indicator Analysis in the European Union: A Machine Learning Approach
Malecha, Jan ; Pleticha, Petr (advisor) ; Semerák, Vilém (referee)
The European Commission annually publishes a European Innovation Scoreboard (EIS) as a tool to measure the innovation performance of the EU Member States. This thesis extends the analysis published in the EIS 2018 in two different manners. The first part, a clustering analysis, examines the partition of the EU Member States to innovation performance groups. The thesis comes with a unique scheme of partition created by using hierarchical clustering. A comparison with the existing scheme shows that the general trends are similar in both schemes. The only main exception is the differentiation of the British Isles and Luxembourg apart from the other high performing countries. The proposed scheme provides insight about the within-cluster similarities, such as the similarity of Finland, Sweden and Denmark and their relative distinction from France, although they belong to one cluster. The second part, a regression analysis, attempts to examine the impact of innovations on real labour productivity. Contrary to existing literature, we do not find a statistically significant relationship between productivity and the components of the EIS. Additionally, the analysis is extended by the lasso estimation that provides a variable selection. The latter approach improves our findings and identifies four EIS...
Personality tests and their linkage to employee productivity
Tsypushkina, Kristina ; Pleticha, Petr (advisor) ; Kraicová, Lucie (referee)
The purpose of this thesis is to evaluate the predictive power of personality traits, depicted by a commercial assessment Predictive Index, on sales employee performance. We utilize non-publicly available company level data from one of the leading firms operating in the consumer finance industry in China. The data set contains over 31 thousands observations on one particular position. Employee performance is measured by their ranking within the top or bottom 20% or 30% based on the sold volume during first month of employment. Using visual analysis and logistic regression, we were able to identify positive correlation between extraversion and sales performance and negative correlation between patience and employee performance. These findings are in line with previous literature. We have also identified that having a colleague at a given sales location has a positive impact on employee performance. Our findings also suggest that it is easier to predict bottom performers when compared to the top ones. Nevertheless, the explanatory variables are able to explain merely 4.7% of variation in employee performance. The added value of personality traits is thus limited in our setting. Such a low predictive power is likely caused by improper administration of the assessment and the fact that the results are...
Does Foreign Aid Decrease Inequality? Evidence from the Most Recent Data
Umlaufová, Anna ; Baxa, Jaromír (advisor) ; Pleticha, Petr (referee)
Income inequality is an alarming issue affecting especially developing countries, yet very scarce attention is paid to how it is influenced by development aid. This study investigates the relationship, focusing on modern approaches to foreign assistance which have changed considerably since 1999. With a sample of 123 developing countries, the effect is estimated using both static and dynamic panel data techniques while controlling for the Kuznets curve. The results show that robust to method and functional form, development aid neither improves nor worsens inequality. Nonetheless, estimating the model for specific groups of countries in the sample yields different, statistically significant results, while also depending on political environment.

Entrepreneurship in the information age: an empirical analysis of the European regions
Pleticha, Petr
Decelerating productivity in recent years raised questions about technology diffusion in the economy. This study focuses on one particular diffusion channel, entrepreneurship, and inspects the mechanics through which it interacts with digitalization. The composite indicator of digitalization is split into separate components which enables analyzing digitalization’s interplay with entrepreneurship as a dynamic process. Based on the econometric analysis of Eurostat regional data covering the period 2008-2015, I find significant links between digitalization and entrepreneurship. Specifically, digitalization is associated with an increase in the rate at which firms are created and with a decrease in their survival rate after 3 years. The paper demonstrates that the interaction is dynamic in its nature as the effects of initial stages of digitalization reverse or vanish in its later phases. A sectoral analysis shows the persistence of the results across industries.\nMoreover, there is evidence that professional, scientific and technical activities are especially sensitive towards digitalization, experiencing strong, yet short-term shock in the firms’ birth, death, and survival rates. Accounting for geographic variation reveals heterogeneity between regions but not large enough to affect the overall results.

Debt Relief and Growth: A Study of the HIPC Initiative
Kutman, Jan ; Cahlík, Tomáš (advisor) ; Pleticha, Petr (referee)
Debt relief is a form of development aid that began to gain importance in the last decade of the 20th century. In 1996 the World Bank and the IMF jointly launched the Heavily Indebted Poor Countries (HIPC) initiative, a comprehensive and structured program designed to provide debt relief for eligible low-income countries. The purpose of my thesis is to investigate, whether debt relief for developing countries over the period 1996-2015 affected economic growth in the recipient countries with particular attention being paid to the HIPC countries. I also investigate whether the impact of debt relief on growth varies conditional on institutional quality. I find that the low-income countries on average did not benefit from debt relief. However, I find that debt forgiveness has enhanced the growth rates in the countries in the HIPC initiative. Based on the results of my regression analysis I did not find evidence that the effectivity of debt relief in either group of countries depends on institutional quality.
Global Imbalances Reflected in the Eurozone's Accounting
Pleticha, Petr ; Janský, Petr (advisor) ; Paulus, Michal (referee)
In this study I investigate the discrepancies between net investment income and development of net international investment position of the Eurozone. To examine these discrepancies, I use the concept of dark matter which enables quantification of such discrepancies. This study has two goals: to present an alternative view on the development of net international investment position in the Eurozone, and to test validity of the dark matter concept by inspecting its interaction with main economic driving forces such as exchange rate or energy prices. Previous research was mainly focused on the United States and did not study dark matter in broader economic context. To date, no systematic analysis has considered the origins of dark matter behavior. The results indeed present the stocks of dark matter behaving in predictable manner, although, contrary to my expectations, they seem not to be connected with exchange rate. The Eurozone's international investment position adjusted for the stocks of dark matter looks also more optimistically, pushing the concerns about global imbalances aside.
