Three Essays on Corporate Financial Misconduct and Market Reactions
de Batz de Trenquelléon, Laure ; Kočenda, Evžen (advisor) ; Havránek, Tomáš (referee) ; Brůna, Karel (referee) ; Karpoff, Jonathan M. (referee)
Chapter 1 Summary of the Dissertation "We are in the golden age of fraud." Jim Chanos, Kynikos Associates, Financial Times 24/07/2020. Beyond the speculations about the consecutive waves of Covid, 2020 will be reminded for one of the most notorious failures of a listed firm, due to a massive accounting fraud: the German payment fintech Wirecard. The firm, with 30 subsidiaries in 26 countries, joined the prestigious DAX index just two years before. The spillovers of the billion-euro fraud range from the arrest of top managers to suspicion of auditors, politicians, and regulatory authorities (BaFin, European Commission, and ESMA), as suggested the Financial Times headline "Why was Frankfurt so blind for so long?"1 Such a failure serves as a reminder of the relevance of financial markets regulation, oversight, and enforcement, in order to protect investors and to encourage compliance with regulations. Research on the relationship between the publication of financial misconducts and financial performance for corporates has continuously grown, as illustrated by the recent in- depth literature reviews undergone by Amiram et al. (2018) and Liu and Yawson (2020). It is fueling regulatory debates on how to enforce more efficiently financial regulations. Some specificities of white-collar crimes must be accounted for...
ECB monetary policy and commodity prices
Aliyev, S. ; Kočenda, Evžen
We analyze the impact of the ECB monetary policies on global aggregate and sectoral commodity prices using monthly data from January 2001 till August 2019. We employ a SVAR model and assess separately period of conventional monetary policy before global financial crisis (GFC) and unconventional monetary policy during post-crisis period. Our key results indicate that contractionary monetary policy shocks have positive effects on the aggregate and sectoral commodity prices during both conventional and unconvetional monetary policy periods. The effect is statistically significant for aggregate commodity prices during post-crisis period. In terms of sectoral impact, the effect is statistically significant for food prices in both periods and for fuel prices during post-crisis period; other commodities display positive but statistically insignificant responses. Further, we demonstrate that the impact of the ECB monetary policy on commodity prices increased remarkably after the GFC. Our results also suggest that the effect of the ECB monetary policy on commodity prices does not transmit directly through market demand and supply expectations channel, but rather through the exchange rate channel that influences the European market demand directly.
Topics in central banking
Brož, Václav ; Kočenda, Evžen (advisor) ; Tůma, Zdeněk (referee) ; Égert, Balázs (referee) ; Martin, Reiner (referee)
This dissertation consists of three research papers dealing with selected issues relevant for central banks after the global financial crisis. The post-crisis world has seen a significant strengthening of the role of central banks with regard to the financial system as well as the real economy. Correspondingly, agendas of some central bankers have grown substantially, encompassing among others monetary policy, financial stability (macro- and microprudential policies) as well as resolution mechanisms. This dissertation thesis reflects the broad focus of some contemporary central banks in three original research articles that concern current unexplored issues for monetary policy and financial stability in the European Union, the Czech Republic, and the United States, potentially bringing policy implications for the relevant authorities. The first article analyzes inflation convergence in the whole European Union (EU) over 1999-2017 and provides comprehensive and robust evidence that the process of inflation convergence among the countries of the EU was not permanently disrupted during the global financial crisis, the European sovereign debt crisis, or the period of zero lower bound interest rates. Specifically, the convergence process did not noticeably weaken after the crisis and the occurrence of...
Stock Market Prediction: A Multiclass Classification on Emotions and Sentiment Analysis for Tweets and News Headlines
Lazeski, Dejan ; Kočenda, Evžen (advisor) ; Vácha, Lukáš (referee)
i Abstract In this thesis, we look beyond extracting binary sentiment in regards to News Headlines and Tweets. As a data source, we target tweets and headlines from well-known financial newspapers, explicitly addressing the top 5 Big Tech com- panies. To examine the effectiveness of sentiment and Ekman's emotions in predicting future stock price movements, we develop multiclass emotion and sentiment classifiers utilizing a supervised learning approach. Moreover, we manually annotate our corpora for positive, negative, and neutral sentiment as well as one of Ekman's emotions: anger, joy, surprise, sadness. We did not confirm any robust correlation between daily stock price movements and the distribution of sentiment and emotions. However, we did observe that tweets are less neutral than news headlines. Finally, we implement a simple invest- ing strategy by extracting sentiment polarity scores using VADER and other metrics such as followers and shares. Two classifiers, SVM and ANN, delivered robust predictions for Google and Amazon compared to weak predictions for the rest of the companies. Nevertheless, the results suggest that sentiment polarity can effectively predict future stock price movements compared to finer-grained emotion classification.

Financing Climate Action: The Pricing of Green Bonds and Its Determinants
Kortusová, Anna ; Kočenda, Evžen (advisor) ; Teplý, Petr (referee)
Green bonds present a promising tool enabling investors in fixed-income mar- kets to finance environmental projects. Yet, the pricing of green bonds with respect to conventional bonds remains an open question. This thesis in- vestigates the existence of a yield differential between green and equivalent conventional bonds in the secondary market. By matching green bonds with synthetic conventional bonds and performing a fixed effects panel regression of the yield spread, we find evidence of a small negative premium associ- ated with green bonds ("green premium"): as a result of high demand from value-seeking investors, the yield of green bonds is on average 1.12 basis points lower than that of their conventional counterparts. The variation in the magnitude of the green premium with bond characteristics is further examined through a cross-sectional regression. We show that external ver- ification of the bond's green credentials and assurance on its post-issuance allocation report significantly increase the estimated green premium. Finally, the green bond's yield seems to decrease in case proceeds are used to finance new projects, while refinancing existing projects results in an increase in the bond's yield. Our findings provide valuable insights into the field of green bond pricing. While the...
Marginal Effect of R&D Expenditures on Value of Technology Companies
Tuček, Lukáš ; Kočenda, Evžen (advisor) ; Čech, František (referee)
1 Abstract Research and development is an inseparable part of technology industry as technology companies, unlike most, rely on R&D not only as means of effi- ciency improvement to existing production, but rather as means of production itself. This thesis presents an alternative approach to R&D intensity measure and applies it in an empirical analysis on technology leaders company data from 2013 through 2018 measuring R&D intensity impact on company market value. Additionally, this thesis explores the differences in impact of R&D on company value dependent on the company's product cycle nature. The re- sults of this thesis are mostly conforming to existing academic literature and show diminishing returns to R&D intensity. A surprising negative effect of a variable comparing given company's R&D expenditures to ones of the segment leader of a given segment has been found. There has been found no lag dif- ference between the groups of companies with open and closed cycle product development.

Exchange Rate Volatility Effect on Trade Balance in Czech Republic
Naletova, Anastasiia ; Kočenda, Evžen (advisor) ; Komárek, Luboš (referee)
This master's thesis investigates the impact of exchange rate volatility on trade balance of the Czech Republic during 2005-2016. The analysis is performed on the constructed panel dataset for 53 trading partners of the Czech Republic by estimating the trade gravity models. The realized volatility values are obtained for 43 Czech koruna pairs against the local currencies. The variables included into the empirical analysis are the GDP and population of the Czech Republic and its trading partners, realized volatility, weighted distance, contiguity, direct access to the sea and information on EU and OECD membership. The methodological approaches in the analysis are calculations of realized exchange rate volatility and for gravity models panel data estimation techniques: pooled OLS, fixed effects and random effects. The gravity models are compared by the formal tests, and the most efficient among them is the fixed effects. The results of the estimated augmented model reveal significant positive impact of exchange rate volatility on trade balance of the Czech Republic. The key variables that have the expected significant positive impact on trade balance are GDP of the Czech Republic and its trading partners in the basic model, population of the Czech Republic and EU membership in the augmented model....
Inflation Targeting vs. Price-Level targeting and their impact on real business
Vejdělek, Robert ; Kočenda, Evžen (advisor) ; Hejlová, Hana (referee)
This thesis investigates the effect of inflation targeting policy on economic performance of selected countries, which are Czech Republic, Sweden and Chile. We use synthetic control method (SCM) as a tool to construct matching countries from control groups, which were selected on the grounds of similar pre-treatment development or other resemblances. The results show significant improvement in GDP per capita growth after imposing the policy in comparison with our synthetic versions of those countries.

Selective Attention in Exchange Rate Forecasting
Kapounek, S. ; Kučerová, Z. ; Kočenda, Evžen
We analyze the exchange rate forecasting performance under the assumption of selective attention. Although currency markets react to a variety of different information, we hypothesize that market participants process only a limited amount of information. Our analysis includes more than 100,000 news articles relevant to the six most-traded foreign exchange currency pairs for the period of 1979–2016. We employ a dynamic model averaging approach to reduce model selection uncertainty and to identify time-varying probability to include regressors in our models. Our results show that smaller sizes models accounting for the presence of selective attention offer improved fitting and forecasting results. Specifically, we document a growing impact of foreign trade and monetary policy news on the euro/dollar exchange rate following the global financial crisis. Overall, our results point to the existence of selective attention in the case of most currency pairs.
Financial Crime and Punishment: A Meta-Analysis
de Batz, L. ; Kočenda, Evžen
We examine how the publication of intentional financial crimes committed by listed firms is interpreted by financial markets, using a systematic and quantitative review of existing empirical studies. Specifically, we conduct a meta-regression analysis and investigate the extent and nature of the impact that the publication of financial misconducts exerts on stock returns. We survey 111 studies, published between 1978 and 2020, with a total of 439 estimates from event studies. Our key finding is that the average abnormal returns calculated from this empirical literature are affected by a negative publication selection bias. Still, after controlling for this bias, our meta-analysis indicates that publications of financial crimes are followed by statistically significant negative abnormal returns, which suggests the existence of an informational effect. Finally, the MRA results demonstrate that crimes committed in common law countries, alleged crimes, and accounting crimes carry particularly weighty information for market participants. The results call for more transparency on side of enforcers along enforcement procedures, to foster timely and proportionate market reactions and support efficient markets.
