Volatility spillovers between crude oil and food commodities
Hrycej, Martin ; Krištoufek, Ladislav (advisor) ; Janda, Karel (referee)
In this thesis, we analyze volatility spillovers between crude oil and food commodities. The principal hypothesis assumes crude oil to behave as a production factor of the agricultural food commodities, thence we are looking for appropriate price effects. We mainly employ wavelet coherence and partial wavelet coherence, which provide us with valuable insight into the commodities nexus, without any strict restraints and assumptions levied on our data. Secondly, we build a DCC-GARCH model in order to model the presumed volatility spillovers. We also perform several simple benchmark analyses, in particular we test for Granger causality and we compute the Pearson correlation coefficients. Our data sample, including 10 commodities and 2 indices, covers the latest decade, significantly widening the existing contextual literature. Our results are mostly compliant with related literature, especially regarding the crude oil-fuels bundle and food commodities bundle, respectively. Considering the main research question of volatility spillovers between food commodities and crude oil, our results are indicating reasonably strong relationships with crude oil for soybeans and corn, leaving cotton and wheat rather on the verge of strong relationship and finding cattle to be completely unrelated.

Mandatory disclosure
Hrycej, Martin ; Gregor, Martin (advisor) ; Džmuráňová, Hana (referee)
The bachelor thesis firstly introduces the problems of mandatory disclosure and describes different attitudes to it. Following is the essential part of the work containing the definition and specification of the studied models of monopoly and duopoly. These models are further analysed and solved using the game theory tools and microeconomics methods for profit optimization. Subsequently the numerical results are evaluated and presented. The obtained results are suggesting whether voluntary or mandatory disclosure regime is more profitable for whom under different conditions - the models parameters in other words. Finally the discussion of the results, the results' relevance and interpretations in the context of related literature are presented. The particular numerical results are of a reasonable nature and rather fit to the literature context than not.
