Debt contracts and stochastic default barrier
Dózsa, Martin ; Janda, Karel (advisor) ; Krištoufek, Ladislav (referee)
This thesis focuses on the theory of asset pricing models and their usage in the design of credit contracts. We describe the evolution of structural models starting from the basic Mertonian framework through the introduction of a default barrier, and ending with stochastic interest rate environment. Further, with the use of game theory analysis, the parameters of an optimal capital structure and safety covenants are examined. To the author's best knowledge, the first EBIT-based structural model is built up that considers stochastic default barrier. This set-up is able to catch the different optimal capital structures in various business cycle periods, as well as bankruptcy decisions dependent on the state of the economy. The effects of an exogenous change in the risk-free interest rate on the asset value, probability of default, and optimal debt ratio are also explained.

Bailouts in banking industry : Curse or salvation?
Šolc, Jan ; Janda, Karel (advisor) ; Hedbávný, Petr (referee)
One of questions discussed in the light of current financial crisis is the problem bailouts in banking industry. This thesis contributes to this dispute by studying the relationship between the probability to be bailed out and the risk appetite of particular commercial bank. The aim of this paper is to analyze this relationship in both, theoretical and empirical way, which is still missing in current literature. We work with two hypotheses in this paper. The first one is that there is a positive relationship between the above mentioned variables while the second one suggests that large commercial banks tend to have higher risk appetite. Our first hypothesis is studied in both ways, while the second one is analyzed only in a theoretical way. In the theoretical part we derive the relationships between considered variables under the general equilibrium framework. In our model we work with an economy with four different agents (namely households, firms, commercial banks and central bank). These derived relationships are then analyzed empirically. We work with a panel data dataset considering the data about 500 commercial banks from 70 countries over the 2005-2008 period. The results of empirical analysis suggest that there is a negative relationship between the probability to be bailed out and the risk...

Financial intermediaries
Frühauf, Ladislav ; Mejstřík, Michal (advisor) ; Janda, Karel (referee)
This diploma thesis deals with the topic of financial intermediaries. These are specialized agents that enter between investors and borrowers on financial markets and facilitate the exchange of financial assets. Their activity increases savings rate and improves effectivity of allocation of resources and thus has a positive effect on economic growth. Financial intermediaries create no real value in the model of complete markets. Classic theories see their role as alleviating market imperfections and center around informational asymmetries, transaction costs and regulatory barriers. These imperfections diminish over time but intermediaries gain on importance. Classic theories seem not to provide sufficient explanation of current development. Several new approaches to the functioning of financial intermediaries are described in this diploma thesis. Powered by TCPDF (www.tcpdf.org)

Recovery rates and the absolute priority rule
Hádlová, Lenka ; Janda, Karel (advisor) ; Havel, Jiří (referee)
Recovery Rates and the Absolute Priority Rule The paper analyses the relationship between expected recovery rates in bankruptcy and the claim's standing within the capital structure of the debtor. According to the absolute priority rule (APR), the claims in bankruptcy should be always repaid in certain order, i.e. each claim can be satisfied only if all relatively senior claims have been repaid in full. But since the APR is often violated in practice, the actual recoveries may differ significantly from the scenario based on the assumption of adherence to the APR. The extent of the APR violations depends highly on the creditors' position in the bankruptcy proceedings within each particular legal system. The paper investigates the characteristics of bankruptcy codes that allow APR violations as well as both ex-post and ex-ante effect of these violations. In this context, we also analyse the New Czech Insolvency Act which will enter into force on 1st January 2008. The paper aims to provide a step towards understanding the problematic relationship between the recovery rates and the creditors' rights protection within particular legal framework.

Pricing of gas swing options
Pokorná, Andrea ; Janda, Karel (advisor) ; Vošvrda, Miloslav (referee)
Even though contracts for the purchase and sale of natural gas providing an offtake flexibility concerning volume and time (gas sales agreements) have been commonplace in the natural gas industry for many years, the development of techniques for pricing them has not followed at the same pace. This thesis is motivated by the changing nature of the natural gas industry in the European Union, which is asking for a mark-to-market evaluation of these contracts. The flexibility provided by these contracts is then regarded as a financial option, called a "gas swing option". Since the gas swing option is actually a set of several American puts on a spread between prices of two or more energy commodities, we devote one section of the text to the theory on spread option pricing. Due to the specific features of the energy markets the existing analytic approximations for spread option pricing are hardly applicable to our framework. That is why we employ numerical methods and model the spot price dynamics through stochastic processes capturing such features. The price of an arbitrarily chosen gas swing option is then computed in accordance with the concept of risk-neutral expectations, i.e. is considered as an expectation of discounted future cash flows for a probability structure called risk-neutral. Finally, our...

Weather risk in the natural gas market
Vyležík, Tomáš ; Janda, Karel (advisor) ; Gapko, Petr (referee)
This thesis deals with the impact of weather on the natural gas market. We describe the development of the natural gas market in the recent past and its current structure. Both these contingencies contributed to the growing importance of hedging against weather risk. Weather is unambiguously the primary determinant of demand in the natural gas market. For that reason, we build a model predicting consumption in the Czech natural gas market with respect to its temperature sensitivity. Such an analysis frequently serves as the first indicator of the need for weather risk hedging, which is since the 90's commonly done with weather derivatives. Therefore we go through so called burn analysis that determines the fair price of an option with regard to past temperature measurements.

Thailand in Regional and Bilateral Free Trade Agreements
Rattanaphan, Chalakorn ; Janda, Karel (advisor) ; Benáček, Vladimír (referee)
The Regional Trade Agreements (RTAs) and the bilateral Free Trade Agreements (FTAs) have increasingly been a new wave of international trade around the world. The countries who seek to establish these agreements, be regionally or bilaterally, realize that the trade agreements are in fact tools to increase trade with their trading partners, to extend and expand their foreign markets, as well as to encourage foreign investments but the overall goal is to strengthen economic tie with the trading partners. Thailand is considered a young and new player in free trade agreements. Given the fact that Thai government's trade policy has been quite ambitious and proactive, Thailand has constantly attempted to establish free trade agreements with its important partners around the world. Regarding Thailand's strong support in export-oriented economy, seeking a greater access to foreign markets through free trade agreements is in fact the country's first priority. Thailand's commitment on regional trade agreement under ASEAN Free Trade Area, and bilateral Free Trade Agreements under TAFTA and JTEPA has provided considerable benefits for Thai economy mainly through an increase in export as well as impor. Moreover, the FTAs have proved to increase competitiveness on Thai products which results in an increase of market...

Implications of inflation differentials on the dynamics of GDP
Strecker, Ondřej ; Janda, Karel (referee) ; Horváth, Roman (advisor)
Inflation differentials within a monetary union translate into differentials in real interest rates. Consequently, their effect (either direct or indirect, through the wealth channel) on the GDP is pro-cyclical in the short term. In the long term, accumulated inflation differentials worsen the real exchange rate and so after some time their anti-cyclical effect will prevail. Concerning the dynamics of the GDP, longer and stronger cycles can be expected. After a theoretical description of the mentionned mechanism this paper quantifies individual effects for the EMU. It also deals with expected changes in cycles' properties after the adoption of Euro. GMM and Kiviet estimates of the panel data model generally prove the statistical significance of the considered effects. Subsequent results show positive relationship between the absolute magnitude of the inflation differentials on the one hand and the growth of the amplitude of the cycles, increase in their length and increase in time needed for the economy to return to the equilibrium after a demand shock on the other hand.

Food vs. Fuel: The Role of Bioenergy
Filip, Ondřej ; Janda, Karel (advisor) ; Pertold-Gebicka, Barbara (referee)
Bibliographic entry Filip, O. (2015): "Food vs. Fuel: The Role of Bioenergy." (Unpublished master's thesis). Charles University in Prague. Supervisor: prof. Ing. Karel Janda M.A., Dr., Ph. D. Length: 121,976 characters Abstract This thesis studies the relationship between the first generation biofuels and selected commodities and assets in the USA, Europe, and Brazil. It is the first attempt to combine the taxonomy and wavelet analyses in a single research application. Our unique dataset comprises 32 weekly price series covering the 2003-2015 time period. First, we employ a method of minimum spanning trees and hierarchical trees to model a biofuel-related price network. We demonstrate a development phase shift between Brazilian and the US/EU biofuel industries. We reveal a strong and stable connection between Brazilian ethanol and its main production factor, local sugarcane. We further find that US ethanol is closely linked to corn. In the contrary, European biodiesel exhibits only moderate ties to its production factors. Subsequent wavelet analysis scrutinizes the identified price connections both in time and frequency domains. Both Brazilian and US ethanols are found to be positively related to their respective feedstock commodities. In particular, feedstock proves to lead the price of the biofuel and not...

Three Essays on the Effect of Alternative Ownership Structures on Investment and Financial Constraints: An Empirical Investigation
Hobdari, Bersant ; Filer, Randall (advisor) ; Maksimovic, Vojislav (referee) ; Janda, Karel (referee)
Three Essays on the Effect of Alternative Ownership Structures on Investment and Financial Constraints: An Empirical Investigation This dissertation consists of three separate papers examining the relationship between investment, financial constraints and ownership structures. In the first paper new and rich panel data for a large and representative sample of firms are used to estimate the sensitivity of access to capital to differing ownership structures. The investment behaviour of firms is examined in a dynamic setting in the presence of adjustment costs, liquidity constraints and imperfect competition. The empirical work is based on the derivation of Euler equations in the presence of symmetric and quadratic adjustment costs and both debt and equity constraints. Whereas the norm is to use ad hoc approaches to model these constraints, our alternative and more consistent approach leads to the inclusion of financial variables in the investment equation in first differences rather than in levels. The GMM estimates confirm the importance of financial factors in determining investment rates and suggest that firms owned by insiders, especially non-managerial employees, are more prone to be liquidity constrained than are others. Among the other groups, somewhat surprisingly, only domestic outsider owned firms...
