The Stagnation of Productivity in the Czech Republic: Does the Country Suffer from Baumol's Cost Disease?
Blaha, Jakub ; Pleticha, Petr (advisor) ; Schwarz, Jiří (referee)
This thesis examines the impact of diverging productivity gains across indus- tries in the Czech Republic and identifies their effect on other economic indi- cators. Using methods standard in the literature about Baumol's model, we analyze yearly sectoral data in the Czech Republic for the period 1995-2015 and examine the presence of Baumol's diseases. Using the econometric concept of fixed effects model, our findings are in line with the predictions of Baumol (1967) as relative prices decline in progressive sectors; and sectoral growth of wages is rather independent of the productivity growth. Additionally, sectoral growth of labour productivity is accompanied by a diminishing share of working hours. Opposite to what Baumol's model suggests, we rejected the hypothesis of the 'constant real share' as productivity growth tend to raise real output. And because the volume of this effect is relatively stronger than the decline in the prices, technological advancement has resulted in nominal output growth. Finally, we have demonstrated that sectoral shifts towards stagnating indus- tries have tended to lower aggregate labour productivity growth. Although the results of our study show the presence of Baumol's cost and growth diseases in the Czech Republic, their magnitude differs considerably from the current...
An Empirical Investigation of Wage Discrimination in Professional Football
Blaha, Jakub ; Kocourek, David (advisor) ; Jonášová, Júlia (referee)
Salary discrimination is a phenomenon that arises from ineffective behaviour of economic subjects. Even though its presence is incompatible with the the- ory of profit maximization, salary inequality still persists in the human society. Nevertheless, the investigation of this topic has been largely unheeded in the environment of professional football. In our empirical research, we use the most recent data to investigate the salary gap between white, African American and Hispanic players in the American Major League Soccer. Besides ordinary least squares method that focuses on the impact of ethnicity for the average player, we adopted the method of quantile regression to reveal wage gap between play- ers with below-average pays. Observing each player's performance for 3 seasons, we uncovered salary discrimination against African Americans and Hispanics in the lowest decile of the salary distribution that amounts to 18.9% and 15.3%, respectively. Furthermore, we utilized the difference-in-differences (DID) esti- mator to find no effect of the increasing level of invested money on the wage gap.

Computational analysis of residual stresses in autofrettaged high pressure rails
Blaha, Jakub ; Petruška, Jindřich (referee) ; Vrbka, Jan (advisor)
The master‘s thesis is aimed on numerical simulation of autofrettage of high pressure fuel vessel – rail in Common Rail system. First there is described Chaboche model, which is later used for simulation of autofrettage. There are described different approaches which can be used to obtain sufficient material model. Then there is observed influence of these different approaches on stress state of rail within the process of autofrettage. Suitability of Chaboche model for autofrettage and re-autofrettage simulations is assessed by comparing with more complex Jiang model. In the end there is a study of influence of autofrettage pressure on different properties, especially on residual stresses.
Criteria of Multiaxial Fatigue Life
Blaha, Jakub ; Slámečka, Karel (referee) ; Horníková, Jana (advisor)
Bachelor’s thesis is about fatigue of materials and options of component’s lifetime determination during multiaxial cyclic loading. First it is described mechanism of initiation and grow of fatigue cracks, then the way of determination fatigue life during uniaxial loading and state of stress during multiaxial loading. Then multiaxial fatigue criteria for life time determination are presented. All criteria are based on critical plane and are divided into stress-based, strain-based and energy-based.
