How Bank Competition Influences Financial Stability
Vildová, Romana ; Horváth, Roman (advisor) ; Teplý, Petr (referee)
How Bank Competition Influences Financial Stability Abstract This paper investigates the link between financial stability and bank competition by means of the Arellano & Bond (1991) GMM model using annual panel data over the period 2000 - 2014 for 205 countries. Our data source is a new, richer and updated dataset The Global Financial Development Database available at World Bank. Due to the specifics of this dataset we are able to use new combinations of measures of financial stability and of bank competition and to study their relationship in greater depth. We find a positive link between financial stability and bank competition. Furthermore, our results provide evidence that it matters what measures of financial stability and bank competition we apply. Lastly, we ascertain that the relationship between financial stability and bank competition does not change over time. Keywords Financial Stability, Bank Competition, Dynamic GMM, the Arellano and Bond Estimator Author's e-mail VildovaRomana@gmail.com Supervisor's e-mail Roman.Horvath@gmail.com

Essays in Empirical Financial Economics
Žigraiová, Diana ; Jakubík, Petr (advisor) ; Witzany, Jiří (referee) ; Teplý, Petr (referee) ; Gächter, Martin (referee)
This dissertation is composed of four essays that empirically investigate three topics in financial economics; financial stress and its leading indicators, the relationship between bank competition and financial stability, and the link between management board composition and bank risk. In the first essay we examine which variables have predictive power for financial stress in 25 OECD countries, using a recently constructed financial stress index. We find that panel models can hardly explain FSI dynamics. Although better results are achieved in country models, our findings suggest that financial stress is hard to predict out-of- sample despite the reasonably good in-sample performance of the models. The second essay develops an early warning framework for assessing systemic risks and predicting systemic events over two horizons of different length on a panel of 14 countries. We build a financial stress index to identify the starting dates of systemic financial crises and select crisis-leading indicators in a two-step approach; we find relevant prediction horizons for each indicator and employ Bayesian model averaging to identify the most useful predictors. We find superior performance of the long-horizon model for the Czech Republic. The theoretical literature gives conflicting predictions on how bank...
