Vplyv vybraných ukazateľov na vývoj ceny Bitcoinu
Slimák, Rastislav
Slimák R. The impact of selected indicators on the price development of Bitcoin. Diploma thesis.Brno: Mendel University, 2022. This thesis deals with the influence of selected factors on the development of the price of Bitcoin. Thanks to literary research of scientific articles dealing with the price development of Bitcoin, specific variables will be selected, which will be subjected to a regression analysis in the practical part. The main benefit of this work is the study of relationships in specific periods, which are defined by Bitcoin halving. In addition to the regression analysis, the work deals with a graphical analysis of selected relationships, an elementary interpretation of the basic properties of Bitcoin together with a more detailed analysis of the mentioned halving and a separate chapter on the basic methods of asset evaluation. The results of the work are critically evaluated in the discussion and compared with the results of scientific articles. In the end, the work tries to summarize whether and or how investor's view of this non-traditional asset has changed in the monitored periods and thus offer an alternative view of Bitcoin's involvement in the portfolio.

Does economic uncertainty spill across countries?
Skákala, Norbert ; Baruník, Jozef (advisor) ; Vácha, Lukáš (referee)
1 Abstract We study economic policy uncertainty spillovers on a panel of ten countries between April 1998 to September 2019. The analysis is performed on the Economic Policy Uncertainty indices data. To measure the spillovers, we utilize forecast error variance decompositions of VAR model. We found that approximately half of the forecast variance can be explained by spillovers shocks across countries. Further, we disentangle the spillover measure to short-, mid- and long-term cycles using frequency domain. Our results suggest that most of the spillovers are caused by shocks into low frequencies, hence with long persistence. Employing quantile regression on equation-by-equation basis to estimate the VAR model, we find that idiosyncratic uncertainty shocks do not propagate strongly at the median but that powerful spillovers occur in the right tail of distribution. Additionally, we perform rolling window estimates of the spillovers. The results indicate strong variation in time, especially during major geopolitical events, such as Iraq War (2003), Global Financial Crisis (2007-09), European debt crisis (2010-12) or Brexit (2016).
