Cheating Behavior in Football
Selep, Ján ; Bauer, Michal (advisor) ; Turnovec, František (referee)
In this thesis I provide statistical evidence documenting rigging of football matches in German long-term championship Bundesliga. For the purpose I use 8326 matches played in top three German long-term competitions through years 1995 -- 2012. The championship is based on a point collection in a standings table divided by strict success margins, e.g. title or relegation. The margins lead to a non-linear incentive structure in which one point is worth more for teams close to the margin. Uncertainty about the final outcome, however, postpones the equilibrating effect to the last rounds of a season. I find evidence of increased point earnings as a reaction on relegation margin closeness at the end of a season. Increased effort of the marginal teams cannot explain the findings as players exert no better performance in the incentive situation. In the same time, their opponents with long margin distance decrease their performance. In addition to that I provide evidence on cheating cooperation proxied by variance of players' performance. The variance does not react on the incentive situation suggesting that teammates behave unitedly. Performance of referees seems to exert stable performance with no reaction on teams' incentives. Overall, the results show strong evidence of systemic point trading in German Bundesliga.

And the winner is... The presence of political slant in the movie production
Selep, Ján ; Stroukal, Dominik (advisor) ; Dušek, Libor (referee)
I study movie studio profit maximization based on an optimization of a political language in the dialogues. I explore the flexibility with which a rational firm slants language of its movies in order to get closer either to a Democratic or a Republican customer. Using computational linguistics I construct vectors of phrase frequency distribution based on a text of almost a decade of U.S. Congress transcripts and 457 randomly chosen movie subtitles. In order to measure distance between the phrase vectors I use chi square statistics and its Monte Carlo approximation. I find no evidence of political slant in movies neither in a movie studio comparison nor for a time-varying comparison of movies in different years. In addition I construct a slant index covering level of political language in a movie. Using the index I find no evidence of impact of political language on movie revenues.

Creative Commons (CC) organization released in 2003 six licenses, which take part of the copyright protection and let other parts fall in the public domain. Consequently, they lower the price of works for future works (inputs) and as an outcome increase creativity and number of works created. On the other hand, CC licenses can serve also as a substitutes to the pure copyright. This thesis examine the impact by analysing United States copyright registration and CC linkback data. The results show insignificance of CC licenses impact on pure copyright licenses. Based on the results I found weak evidence for complementary relationship between the two. Finally, I show that there is no difference between the types of CC licenses as an determinants of number of pure copyright licenses.
