The Mindful Body on the Edge: Forming the Adrspach Climbing Body
Růžičková, Johana ; Spalová, Barbora (advisor) ; Grygar, Jakub (referee)
This thesis focuses on the mode in which climbing in Adrspach rocks acompannied by risk forms the Adrspach climbing body. Its aim lies in contributing to current knowledge of individuals voluntarily participating in risk taking through the eyes of anthropology of the body. The thesis is based on edgework (Lyng, 1990), social-psychological theory of risk-taking made by Stephen Lyng and the following researches of other authors (West and Allin, Brymer, Laurendeau) and it borrows the term of edge as the key concept of forming a risk-facing body. Such body is created on the anthropological basis of Nancy Scheper-hughes and Margaret Lock's mindful body, Thomas Csordas's somatic modes of attention and Marcel Mauss's habitus. The idea of Adrspach climbing body also derives from an already existing concept of climbing body of british "adventure climbers" described by Neil Lewis. The intention of this approach is to connect these theoretical streams and in this fashion widen the current knowledge of human perception of risk-taking and the emotion of fear and to present the form of human body facing danger in relation with both individuality and social bonds. The findings about Adrspach climbing body are based on both ethnographical and autoethnographical research conducted in Adrspach and nine in-depth...

Hormones and Competitive Behavior
Sýkora, Zdeněk ; Cingl, Lubomír (advisor) ; Bauer, Michal (referee)
The thesis aims to contribute to the literature on the biological underpinnings of important economic behaviors. Financial markets can become dangerously unstable from many reasons such as the hormones contained in our bodies. We primarily focus on the effect of basal testosterone and cortisol on willingness to compete and risk taking. We also investigate their interaction called the dual-hormone hypothesis, because it has not been sufficiently analyzed and replicated so far. We run a controlled laboratory experiment with 96 university students and have gender-balanced dataset, thus we can also examine gender differences. We find no support that higher testosterone increase willingness to compete in men as opposed to most of the recent literature. Moreover, higher levels of testosterone decrease competitiveness but only for women. We further find positive effect of the 2D:4D ratio for women and negative effect of trait anxiety for men on competitiveness. There are also substantial gender differences in competitive and risk taking behavior. We cannot confirm the dual-hormone hypothesis for willingness to compete. But we find significant support for the dual-hormone hypothesis for risk taking for women and with negative effect of testosterone on risk taking. The effects stay robust even after...

An alternative view on Czech banking sector's riskiness
Kubeš, Jan ; Teplý, Petr (advisor) ; Troch, Tomáš (referee)
Riskiness of Czech banking sector is subject of interest of this thesis. Since the beginning of 21st century, there is moderately growing number of banks and their overall profitability expressed in absolute values is increasing. Ratio of non-performing loans to total loans is also displaying optimistic values. Four indicators of riskiness are studied through data about Czech banks from 2008 to 2015. These indicators are: z-score, leverage ratio, RWA density and ratio of non- performing loans to total loans. Rather low correlations among these indicators are found, the highest correlation (0,670) is between leverage ratio and RWA density, on the other hand the lowest one (0,093) is between z-score and NPL ratio. In aggregate form are three of the indicators displaying stable trend to lower riskiness in 2008-2015 period, the same can be stated about NPL ratio in 2010-2015 period. Then is regression analysis employing fixed effects estimation and random effects estimation used, with the aim to identify determinants of the four indicators. Size of banks expressed in logarithm of total assets is significant in only one model with RWA density on the place of dependent variable. This significance is at 10 per cent level and corresponding coefficient is negative. In contrary, growth of assets and dummy...

Management Board Composition of Banking Institutions and Bank Risk-Taking: The Case of the Czech Republic
Žigraiová, Diana
The paper investigates how the management board composition of banking institutions affects their risk-taking behavior in the Czech Republic. More specifically, we examine the effect of average director age, the proportion of female directors, the proportion of non-national directors, and director education level on four different bank risk proxies. We build a unique data set comprising selected biographical information on the management board members of Czech financial institutions holding a banking license over the 2001–2012 period. Our most robust finding is that higher proportions of non-national directors increase bank risk as measured by profit volatility and reduce bank stability as captured by the Z-score for the Czech banking sector overall and for the segments of general commercial banks, small and mid-sized banks and adequately capitalized banks. Moreover, we also detect risk-increasing implications of board size for the segments of building societies and small and mid-sized banks. As for average board tenure, its effect on risk-taking varies depending on bank characteristics. We find mixed evidence on the effect of female directors and do not find any strong effect of directors’ age on risk in the Czech banking sector. All in all, the results of our analysis are subject to the proxy of bank risk used. The reader should keep in mind that higher absolute level of bank risk is not necessarily unfavorable as it does not capture if risk-taking behavior is excessive for a given return.

Measuring excessive risk-taking in banking
Podpiera, Jiří ; Weill, Laurent
In this paper writers propose a new approach to the assessment of excessive risktaking by a banking sector. They use the portfolio approach to assess the optimal risk-return combination of a bank’s portfolio, based on data for 32 categories of loans. It provides a benchmark for the optimality of the bank’s portfolio.

Monetary Conditions and Banks’ Behaviour in the Czech Republic
Geršl, Adam ; Jakubík, Petr ; Kowalczyk, Dorota ; Ongena, Steven ; Alcalde, José-Luis Peydró
This paper examines the impact of monetary conditions on the risk-taking behaviour of banks in the Czech Republic by analysing the comprehensive credit register of the Czech National Bank. Our duration analysis indicates that expansionary monetary conditions promote risk-taking among banks. At the same time, a lower interest rate during the life of a loan reduces its riskiness. While seeking to assess the association between banks’ appetite for risk and the short-term interest rate we answer a set of questions related to the difference between higher liquidity versus credit risk and the effect of the policy rate conditioned on bank and borrower characteristics.
