Aspects of public procurement in context of Criminal Law
Svatoň, Michal ; Jelínek, Jiří (advisor) ; Šelleng, Dalibor (referee)
The topic of this thesis is the analysis of criminal activities related to public procurement, the analysis of individual crimes that affect public procurement, the analysis and analysis of individual means of evidence used by law enforcement agencies to detect and prove criminal activities. At the same time, the thesis deals with and analysis of selected criminal offences that are imposed in connection with criminal activities related to public procurement. The aim of the thesis is then to evaluate the possible shortcomings in the legal regulation and the proposal for modification of the legal regulation. To this end, the thesis also deals with a comparison with foreign legislation in order to possibly inspire de lege ferenda proposals. The thesis is divided into five thematic chapters. The first chapter analyses the existing regulation of public procurement with the definition of concepts crucial for the criminal law regulation of public procurement. The author also briefly makes a comparison with the previous legal regulation, taking into account the fact that the terms mentioned in the criminal regulation refer precisely to the previous legal regulation of the Public Procurement Act. For this reason, the author also compares the concepts of both the Public Procurement Act and the Public...

Ghana cocoa farmers' survey: chocolate economics
Svatoň, Michal ; Janský, Petr (advisor) ; Průša, Jan (referee)
In this thesis I evaluate long-term productive and economic impacts of the Cocoa Abrabopa Association, a private sector initiative providing fertilizer and other agrochemicals to Ghanaian cocoa farmers on credit with a joint lia- bility. Both the productive and economic returns of the program are expected to be higher in the latter years of sustained membership in the program due to the accumulation of nutrients in the soil and the possibility of the exten- sion of the size of the loan provided by the program. Earlier work focused only on the estimation of the effect of adoption of agricultural technology but did not allow to examine possible difference in returns of a longer par- ticipation. This thesis contributes by evaluating the impacts in the 1st, the 2nd and the 3rd year of the CAA membership and their comparison. By constructing and estimating a model for the impacts of longer participation I confirm the hypothesis of higher economic returns during the 2nd and the 3rd year of participation in the CAA program. The evidence which would confirm the hypothesis of higher agronomic returns has not been found in the case of CAA. 1

Application of quantile autoregressive models in minimum Value at Risk and Conditional Value at Risk hedging
Svatoň, Michal ; Baruník, Jozef (advisor) ; Vošvrda, Miloslav (referee)
Futures contracts represent a suitable instrument for hedging. One conse- quence of their standardized nature is the presence of basis risk. In order to mitigate it an agent might aim to minimize Value at Risk or Expected Shortfall. Among numerous approaches to their modelling, CAViaR models which build upon quantile regression are appealing due to the limited set of assumptions and decent empirical performance. We propose alternative specifications for CAViaR model - power and exponential CAViaR, and an alternative, flexible way of computing Expected Shortfall within CAViaR framework - Implied Expectile Level. Empirical analysis suggests that ex- ponential CAViaR yields competitive results both in Value at Risk and Ex- pected Shortfall modelling and in subsequent Value at Risk and Expected Shortfall hedging. 1
