Kulhánek, Vít ; Kalabiška, Roman (advisor) ; Bauer, Michal (referee)
This thesis aims to examine the e ect of vaccination on the development of the Covid-19 pandemic. The three key variables are used as dependent vari- ables: the number of new cases, new deaths, and hospitalization. The dataset containing numerous countries and capturing periods from 2020 to 2022 was obtained, therefore a panel data estimator was employed. Moreover, the Czech Republic and Israel were selected for deeper investigation, and their data were filtered from the dataset. The data structure changed from panel data to time series, so OLS regression was selected as an appropriate method. In all mod- els, vaccination variables and also several others were included in lags because a time gap is necessary to increase individuals' immunity in the case of the vaccine. Last but not least, the excess deaths analysis is created and focuses on investigating excess deaths caused primarily or secondarily by the Covid-19 pandemic. Furthermore, it predicts the amount of money not paid in the form of pensions till 2030 for the elderly who are included in the excess deaths. Fi- nally, it compares this amount of money with the expenditures associated with vaccine purchases.

Salary determinants of NHL players
Kulhánek, Vít ; Kalabiška, Roman (advisor) ; Matoušek, Jindřich (referee)
This thesis aims to examine the effect of NHL players' performances and physical properties on their salary. There have been studies about NHL salary determination, however papers are many years old and the significances may change. Models in this thesis were formulated with original structure of variables based on data from the latest regular season 2018-2019 in order to depict the most recent relationships determination. Furthermore, including the separated models for all position is not observed in any of mentioned papers. Performance variables as well as physical factors were found significant, however its significances levels and values of estimates differ among models. This thesis further extends the research by capturing the effect of goodwill that to the best of our knowledge, has not been studied yet. Moreover, it provides a quantile regression for the group of players with the highest salaries that results in differences among variables significances and estimates compared to the joint model. Goaltenders' model is very rarely investigated, since their variables differs compared to the skaters, therefore it brings new evidence of their salary determination. The goalies' model shows positive and significant result of age and games played. JEL Classification C01, C12, C51, Z20 Keywords...
