Measuring Market Power: The Czech Market of Mobile Operators
Kolomazníková, Barbora ; Koubek, Ivo (advisor) ; Hayat, Arshad (referee)
The main focus of the thesis is the measurement of market power. Since market power is a determinant of the degree of competition, its measurement is the key feature of competition policy. We present various methods for assessing market power. One of the most famous ones are Lerner index and Herfindahl-Hirschman index, both of which belong to SCP paradigm. Another group of measures are the NEIO models, which provide the empirical analysis of relevant markets. For the estimation of market power, we have chosen the czech market of mobile oper- ators. We examine the three largest operators (i.e. O2, T-Mobile and Vodafone) in the period 2000-2013. Firstly, the model of Röller and Parker (1997) is used to identify the market's structure. Secondly, we employ the Appelbaum's (1982) industry-level measure to estimate market power. Keywords: market power, market structure, Lerner index, competition, industrial orga- nization, mobile operator, telecommunications Supervisor's e-mail address: koubek@fsv.cuni.cz Author's e-mail address: barbora.kolomaznikova@centrum.cz 1

Breaking-up activity of firm and the transaction cost
Kosturák, Matej ; Koubek, Ivo (advisor) ; Kocourek, David (referee)
In my work I focus on the essential components of the bankruptcy and insolvency problem. The basis for understanding of mentioned problem was study of capital structure and it's connection with world of insolvency. Secondly I focus on different aspects of qualitative analysis of bankruptcy, starting with definition of different terms, many times unprofessionally misused, followed by description of four main processes of bankruptcy. These processes connect fundamental causes of bankruptcy with financial and nonfinancial consequences. For an economic paper, it is quiet extensively concerned with insolvency law, concretely with new Czech norm, which is in force since 2008. From legal definition of default, through initiation of insolvency proceeding to the individual options of solution, the reader can clearly understand the core of this paper. As particular contribution I regard part of the paper, where I examine 160 cases of Czech companies and persons under liquidation process. Among the most significant conclusion I consider finding of quite significant differences in the court proceedings of Czech courts, the length of the insolvency proceedings and each of its phases and the ratio of satisfied claims of secured as well as unsecured creditors.

Šopovová, Andrea ; Koubek, Ivo (advisor) ; Netuka, Martin (referee)
This paper studies an Oligopoly theory, which is applied on a mobile phone market in the Czech republic in order to measure and analyze the market performance throughout the years (1995-2008). We present several approaches of measures of market performance. The chosen econometric model then gives the results. A central question we ask is whether and how much the behaviour of operators changed with an entry of new provider. We get rather expected results. Moreover, we include a critical evaluation of our model and analysis.
