Private and public returns to business R&D spending in Czechia
Pleticha, Petr
This study presents the first estimates of the relationship between business R&D capital and value added by sector in Czechia. The goal is to assess both direct effects of R&D spending in respective industries, and indirect, spillover effects on the rest of economy. We apply well-established regression approaches, using sectoral data from manufacturing and selected service sectors from 1996 to 2015. Because R&D spending and public R&D subsidies have soared in recent years, such an analysis has been long overdue.
Best predictors of apartment prices: Empirical Evidence from Czechia
Šváb, Ondřej ; Pleticha, Petr (advisor) ; Vozková, Karolína (referee)
It is essential to control for property price determinants since there could be created the price bubble, and its burst would have harmful effects on the economy. Thus, this bachelor thesis aims to show the best determinants and models for forecasting the apartment prices in Czechia and its regions with the use of panel data and time series from the Czech Statistical Office. After stating hypotheses of variable's expected impacts on apartment prices, the most important determinants appeared to be the average wage, unemployment rate, natural population growth, and the building plot price. The best results are found by using econometric regressions as the fixed effects, the first differences or the classical ordinary least squares method. I also use the heteroskedasticity and autocorrelation consistent standard errors for better robustness of coefficients. Moreover, the lasso method is applied for dealing with multicollinearity and over-fitting, which are fixed by the variable selection. In most cases, the lasso improved prediction accuracy. However, the first difference regressions worsen the forecasts after the lasso penalisation. 1
Impact of zombie firms on the weak post-crisis growth of the Slovak Republic
Bosák, Martin ; Pleticha, Petr (advisor) ; Kočenda, Evžen (referee)
According to the Convergence Analysis of Slovakia from 2017, the current subject of Slovak economic growth and convergence is the slow growth in productivity as relative productivity of Slovakia to the EU average was decreasing in the period from 2014 to 2017. Moreover, it shows that Slovakia is one of the countries with low efficiency of using labour and capital, which means that there is an occurrence of misallocation of resources. A significant role in this downturn according to recent literature might be the occurrence of zombie firms, which are old companies that do not have sufficient profitability to cover their interest expenses for a longer period. This thesis examines zombie firms and their significance in stifling productivity performance. Using a rich firm-level dataset for Slovakia, we research the determinants of zombie companies in Slovakia. Controlling for cyclical effects, this thesis reveals that zombie enterprises over the period from 2003 to 2013 were significantly less productive compared to their healthy competitors. In addition, we find out that occurrence of zombie companies curbs the growth of healthy companies and has a negative impact on the economic output overall. These results are raising several issues for public policy as it needs to mitigate this cause of...
Occupancy Rate in Paid Parking Zones in Prague
Kašparová, Amálie ; Pleticha, Petr (advisor) ; Kukačka, Jiří (referee)
The bachelor thesis deals with occupancy measurement in Paid Parking Zones (PPZ) in Prague with system of random monitoring by special vehicles equipped with cameras. It introduces distinction between immediate occupancy, i.e. the percentage use of parking spaces in a given area in a given time and effective occupancy, i.e. the percentage use of time parking capacity in a given time interval. Since the effective occupancy cannot be determined in real conditions of PPZ by random monitoring, the method of simulation of parking in the model area was chosen. The model was created based on parameters expected parking time of visitors and residents and parking interest. The model simulates the use of parking capacity and its output are simulated effective and immediate occupancy. The basic parameter values were obtained by analysing the real data for 2018 from PPZ. The goal of the thesis was to analyse under which conditions and number of measurements, the immediate occupancy is a good estimate of effective occupancy. In total, 10500 simulations were performed for 21 different parameter combinations resulting in an effective occupancy of about 45%-95%. The results of the simulation show, that five measurements in one working week are sufficient to estimate effective occupancy in the same time interval....
Collaborative purchasing in public procurement: A comparative study
Křivohlavý, Tomáš ; Palanský, Miroslav (advisor) ; Pleticha, Petr (referee)
This bachelor thesis deals with the issue of collaborative purchasing in public procurement. We describe possible effects of centralized purchasing and define the objectives and strategies of the European Union regarding procurement centralization. Then, we examine the effects of centralized procurement based on a unique dataset of tenders from the whole European Union using Quasi-Maximum likelihood estimation. We find a positive effect of central procurement on competition in three procurement sectors. We also find that the effect is higher in countries with a higher degree of corruption. Centralized purchasing is criticized because of possible disadvantaging of small enterprises. We show that this strategy has a negative effect on the probability of awarding contracts to small or medium companies in two procurement sectors. One of the recommendations of the European Union to solve this problem is the usage of tenders with multiple selection criteria. However, our results do not confirm the validity of this recommendation.
Impact of zombie firms on the weak post-crisis growth of the Slovak Republic
Bosák, Martin ; Pleticha, Petr (advisor) ; Teplý, Petr (referee)
Productivity growth is diminishing among OECD countries, coupled with increased differences in productivity development among enterprises and misallocation of resources. A recent literature focuses on the role of zombie firms, defined as old firms that have persistent problems meeting their interest payments, to explain these developments. This thesis examines the extent to which zombie firms are stifling labour productivity performance. Using a rich firm-level dataset for Slovakia, we assess the role of zombies on firm dynamics. We confirm the results that prevalence of zombie firms curbs the growth of healthy firms and thus dragging aggregate productivity down. Controlling for cyclical effects, our analysis shows that zombie firms over the period 2003-2013 are significantly less productive within industries than their healthy counterparts. Furthermore, a higher share of industry capital or employment sunk in zombie firms is associated with lower labour productivity, investment and employment growth of the typical non-zombie firm, which results in less productivity-enhancing capital reallocation. These results highlight the role of public policy in addressing prevalence of zombie firms, fostering a more efficient resource allocation and enabling productivity growth.
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.
