Dynamic Network Risk across main U.S. sectors
Malecha, Jan ; Baruník, Jozef (advisor) ; Čech, František (referee)
We study the effects of financial networks formed by the connectedness of stock return volatilities within sectors of the S&P 500 Index. We test whether the risk arising from dynamic volatility connections is priced in the cross-section of stock returns. Separately, for each sector, we estimate the dynamic network formed by firm-level realized volatilities from 2006 to 2018. We study how connectedness differs across sectors. Comparing the sector results, we conclude that there is a homogeneous pattern that describes the development of volatility connectedness. The pattern holds across all sectors throughout the studied period and is shaped by major financial events. We create risk factors that attempt to assess the risk arising from dynamic volatility connections. For each sector, we create a factor model that we test using the Fama-Macbeth regression. The results provide evidence that the created risk factors are priced in four out of ten sectors, that is, significant results are found in the Energy, Financials, Industrials, and Consumer Discretionary sectors.

Afghanistan as an insulator of regional complexes? Sectoral analysis of Afghan security
Haringová, Ingrida ; Karásek, Tomáš (advisor) ; Ludvík, Jan (referee)
The goal of master thesis Afghanistan as an insulator of regional complexes? Sectoral analysis of Afghan security was to analyze security of Afghanistan based on sectors and from the viewpoint of Regional security complex theory developed by Barry Buzan and Ole Wæver. The purpose of the thesis was to review categorization of Afghanistan as an insulator and identify factors which undermine his status as such. Afghanistan's location is very much unique because it lies among three different regional security complexes - Central Asia, The Middle East, and South Asia. The analysis was conducted through combination of a) discourse analysis of statements and speeches of president Ashraf Ghani and CEO Abdullah Abdullah (2014 - ) and added with information from the Ministry of Foreign Affairs and b) material relations in regions, such as trade routes, military aid etc. and c) history. Analysis is based on military, political, and economic sectors. The discursive analysis pays attention to the perception of Afghanistan on itself with focus on institutional discourse and broader debate in the English-speaking afghan media.
