Modeling Liquidity Adjusted Value at Risk Using Quantile Regression Analysis
Nguyen Quang, Dung ; Baruník, Jozef (advisor) ; Burda, Martin (referee)
The master's thesis deals with modeling Value at Risk model adjusted by liquid- ity. For this purpose we use quantile regression analysis and liquidity proxies. We find out that Garman-Klass volatility estimator can be very useful in pe- riod 2000-2008 for the small and mid-size semiconductor companies but not in period 2008-2015. The NASDAQ composite Garman-Klass volatility is useful for all semiconductor companies for period 2008-2015. We might conclude that from the outbreak of the crisis returns of all semiconductor companies might depend on movement of NASDAQ composite index. We use Amihud and Roll measures as the liquidity proxies but the results are not persuasive regardless or size of companies and period we analyzed.

Pro tuto analýzu jsme použili kvantilovou regresi a proměnné indikující likviditu. Došli jsme k závěru, že Garman-Klass volatility estimator je velmi užitečný pro malé a středně velké firmy operující na trhu s polovodiči a to v ob- dobí 2000-2007, nikoliv však období 2008-2015.

The Institutional Analysis of Banking Reforms in Vietnam
Nguyen Quang, Dung ; Mertlík, Pavel (advisor) ; Levely, Ian Vandemark (referee)
The main goals of the bachelor thesis is an institutional analysis of the banking reform in Vietnam. The author analyzes how the banking reform influences the institutional development. Modern institutions require flexible and efficient rules, both formal and informal. Hence, a legal framework is analyzed as well especially as to whether the de jure banking legal framework corresponds with the de facto one. Liberalization and internationalization of Vietnamese economy has a big impact on the development of the banking sector. Albeit institutions are de jure well developed they are not sufficiently efficient due to the inability of enforcement of laws, lack of confidence, and corruption in the banking sec- tor. Vietnam has chosen the right direction but the establishment of efficient institutions has to go hand-in-hand with the change of informal rules. Since the diffusion of information is limited due to lack of codification of laws, connections relationship and informal rules play a crucial role in the banking sector. Infor- mal rules are deeply entrenched and tenacious, and hence difficult to change in the short time. 1
