Development of Game Application for PC in Unity Environment
NOVÁK, Jiří
The main goal of this project is to create an application in form of a PC game. The project focuses on game engine Unity and programming language called "C sharp". Using game engine is a simpler way of coding games for multiplatform environment. It implements commonly used game functions that take care of basic game objects behaviour. Game of this project is 2D and uses sprites for graphics and animations. In this case technique called Pixel art is used. Genre of this game is a platformer slightly leaning to "Metroidvania". A player character can move vertically with the option to jump horizontally. Environment contains traps and enemies which the player tries to avoid or eliminate. During the game progress can player reach different bonuses and score points. The game includes multiple levels with different enemies and difficulties.
Stability and control of dynamical systems used in modeling an airplane motion
Novák, Jiří ; Šremr, Jiří (referee) ; Nechvátal, Luděk (advisor)
A modern aircraft (or another machine moving in the air) usually does not rely on its structural stability only. In fact, the motion is conventionally stabilized using a loop feedback control. A dynamical system, which models the aircraft's position and orientation in time, reacts on the state variables, hence, the control signal is dynamically changed. This bachelor's thesis deals with deriving the equations of motion for small perturbations of the state variables as well as with stability and control of such a system of equations. In addition, comparison of both a nonlinear and a linearized model is a part of this work. The programming language Python is used for testing on several examples of a concrete aircraft.
The impact of foreign and domestic M&A on acquirer's stock prices in Central and Eastern Europe
Lukashova, Anna ; Kočenda, Evžen (advisor) ; Novák, Jiří (referee)
The primary objective of this thesis is to investigate the value implications of the mergers and acquisitions deals initiated by the firms from the CEE region. We examine the sample of the 203 M&A announcements made by the bidder firms from the two major economies in the region-Poland and Russia-over the period 2006-2016. We apply the event study methodology to investigate the effect of the M&A announcement on the wealth of the acquirers' shareholders. The results demonstrate that on average investors of the Polish acquirers receive positive short-term wealth effect, while the investors of the Russian firms lose in short-term value. Our empirical findings provide partial support for the positive wealth effect when acquirers target the strategically important asset. Our results hold after controlling for the number of firm and transaction-specific characteristics.

Size and Value Premiums in Returns of the Central and Eastern European (CEE) Stocks
Rolevski, Borche ; Novák, Jiří (advisor) ; Vacek, Pavel (referee)
This thesis provides evidence of size and value premiums in returns in the Central and Eastern European (CEE) region, through its analysis of financial markets in 12 countries. Following the portfolio construction methodology of Fama and French (1996) we use a sample of 1245 stocks and record that small stocks outperform big stocks (size premium) and value stocks outperform growth stocks (value premium). In addition, we create nine portfolios to test the Fama and French three-factor model and show that the factor-mimicking portfolios that have been documented in the developed markets, SMB (small minus big) and HML (high minus low), also capture most of the cross-section variation in average stock returns in the CEE region. We demonstrate a similar pattern in terms of size return as documented in the U.S. market, but with small differences in the value returns found. Although the Gibbons-Ross-Shanken (GRS) test does not reject the null with 95%, we do not agree that the model completely explains the variation in average returns across the portfolios. The GRS rejects the null at 90% and implies that other factors are omitted from the model. Nevertheless, this thesis contributes to the literature applying asset pricing models to the CEE region, and should provide insights to investors active in the CEE...
The Effect of Litigation Risk on Earnings Management in the Proximity to Debt Covenant Violation
Britskiy, Andrey ; Novák, Jiří (advisor) ; Červinka, Michal (referee)
This bachelor thesis aims to establish a relationship between earnings management in proximity to debt covenant violation and the presence of litigation risk. Central testable concept is Watts and Zimmerman (1990) debt covenant hypothesis according to which managers tend to manipulate earnings to reduce the possibility of violation of their company's debt agreement. This setting allows investigating whether the risk of litigation is an effective regulatory mechanism which improves the contracting usefulness of accounting numbers and better align the interests between creditors and company managers, thus making debt covenants more reliable as monitoring mechanisms. Due to inconclusive results, this thesis was unable to establish whether the threat of litigation can discipline managerial reporting practices and deter misreporting for the companies with substantial debt covenant incentives.
The Impact of Mergers and Acquisition Activity on the Time Series Variation in the Stock Size Premium
Kaplan, Robert ; Novák, Jiří (advisor) ; Geršl, Adam (referee)
This work studies whether intertemporal variation in future takeover activity explains intertemporal changes in stock size premium. Taking into account that takeover activity involves 2-9% of firms every year and building upon existing research stating that small firms are more likely takeover targets, receive 40% higher takeover premium than large firms, we argue that small firms benefit from high takeover activity more than large firms and size premium should be more pronounced in the time of high takeover activity. We study takeover activity as well as stock size premium on aggregate level and test whether size premium can be explained by the expected takeover activity, i.e. its change compared to past. We find that change in takeover activity in the next six months versus last six months is positively correlated with size premium. Additionally, we construct a simple predictive model for estimating future takeover activity. The relation between size premium and change in takeover activity remains significant when we use forecasted values given by the predictive model instead of true future values in the model.
Effects of the acquisition-based majority ownership: Evidence from the Czech firms
Gábrišová, Nela ; Kočenda, Evžen (advisor) ; Novák, Jiří (referee)
The thesis analyses Czech limited liability and joint stock companies, where a change of majority shareholder occurred between 2005 and 2011, from the per- spective of their performance 3 and 5 fiscal years after acquisition. The main objective of the research is to compare realised acquisitions between them- selves according to the target's size, and to the industrial relatedness of the acquisition target and acquirer as divided to: horizontal, vertical, financial acquisitions, and acquisitions completed by natural persons. Furthermore, var- ious financial variables potentially affecting operating profitability expressed as EBITDA margin, and other performance indicators are explored. Application of OLS regression on cross-sectional data structure for the two observed post-acquisition periods, and OLS with fixed effects on two-period panel data, provide similar results leading to conclusion that optimisation of variable costs relative to revenue after acquisition has the largest positive im- pact on EBITDA margin. No evidence is found for influence of types of acqui- sitions. Contribution to the research in M&A field is brought thanks to the fo- cus on Czech acquisitions that so far have not been systematically examined, and thanks to analysis from the perspective of acquisition targets' financial...
The Impact of Just-in-Time Inventory Management on Business Cycle Severity
Chalupová, Karolína ; Novák, Jiří (advisor) ; Hanus, Luboš (referee)
This thesis examines the impact of the just-in-time management (JIT) on volatility of inventory and the magnitude of inventory recessionary cuts. Firms' inventory is an important macroeconomic variable - prior research shows that a decrease in inventory volatility is likely an important source of the Great Moderation and that inventory cuts are a crucial part of GDP decreases during recessions. My results show that JIT decreases volatility of inventory change and makes the recessionary inventory cuts milder. Combined with previous research, the results imply that likely, JIT is an important source of the Great Moderation and mitigates recessions. I test the hypotheses with quarterly 1975-2014 data on U.S. publically traded manufacturing firms, consisting of 116 JIT adopters and 116 matched control firms.
Bias and Accuracy in Equity Research: The Case of CFA Challenge
Hloušek, Pavel ; Novák, Jiří (advisor) ; Máková, Barbora (referee)
This thesis analyses drivers of optimistic bias in equity research and substance of ability in explaining differences in accuracy among equity analysts. I have shown the existence of a relevant reason for optimistic bias in equity research, which is not related to conflict of interest - the usually referred driver of the bias. Then I have supported the stream of literature showing that analyst's ability is not a strong determinant of analyst's accuracy. A new perspective on the topics is offered by using a sample of equity reports from valuation competition CFA Research Challenge. Contribution of the thesis lies (i) in working with a sample of analysts who do not face the conflicts of interest proposed by the literature to be causing optimistic bias, which offers a unique opportunity to test whether such conflict-of- interest-free analysts issue biased recommendations and in (ii) using success in CFA Challenge as a new proxy for ability of equity analysts. The methods used are an analysis of bias and accuracy of target prices, hit-ratio of investment recommendations, and analysis of returns - estimated by CAPM, Fama French three-factor model and Carhart four-factor model.
