Effect of the Flat Tax Reform on Labour Supply Elasticity at the Intensive and Extensive Margins: Evidence from the Czech Republic
Tomo, Ján ; Pertold-Gebicka, Barbara (advisor) ; Šťastná, Lenka (referee)
The thesis deals with the estimation of labour supply responses to the personal income tax reform in the Czech Republic adopted in 2008 by applying quasi experimental design known as "difference-in-differences". By exploiting the different change in the effective tax rates for various population subgroups as a natural experiment and using microdata from European Labour Force Sur- vey we constructed the treatment and control groups according to the highest attained level of education serving as a proxy for an income range that assigns an individual to the particular tax bracket before and after policy change. Analysing one-person households we found significant negative effect on the labour force participation and significant positive effect on the hours work of the treated by comparing these outcomes for the treatment and control groups in the baseline and follow up periods before and after the reform. JEL Classification C21, D04, H24, H31, I38, J22 Keywords tax reform, labour supply, natural experiment, difference-in-differences Author's e-mail janxtomo@gmail.com Supervisor's e-mail gebicka@fsv.cuni.cz

Estimating the elasticities of labour supply for SMEs in Bosnia and Herzegovina
Šabić, Ada ; Strielkowski, Wadim (advisor) ; Želinský, Tomáš (referee)
This Master thesis aims at testing the intertemporal substitution hypothesis (ISH) for small and medium enterprises in Bosnia and Herzegovina. We predicted a positive relationship between the hours worked and the transitory changes in wages, and tested the hypothesis using the data collected via surveys of small entrepreneurs in North-Western Bosnia and Herzegovina; collecting data on daily income and the hours worked. The estimated wage elasticities are positive and different from zero, according to which it appears that the hypothesis of negative wage elasticities has no empirical evidence in the case of Bosnian and Herzegovinian entrepreneurs. This result implies that the intertemporal labour substitution hypothesis found supportive evidence and that we can reject the daily targeting hypothesis. We also argue that entrepreneurs tend to pursue profits across working days because their main motive for running a business is the accumulation of capital and wealth, so that they follow the pattern of intertemporal labour substitution. The findings can be explained by an unfavourable business climate in Bosnia and Herzegovina, which is a result of a long-lasting transition process the country is still undergoing. Keywords: labour supply, elasticity, intertemporal substitution, daily targeting, SMEs,...

Daily targeting versus intertemporal substitution - estimating elasticities of labour supply on the example of small and medium enterprises (SME) in the Czech Republic
Hrdý, Rostislav ; Strielkowski, Wadim (advisor) ; Rečka, Lukáš (referee)
This bachelor thesis explores labour supply on the example of small and medium enterprises in the Czech Republic. It contrasts two basic hypoteses - the hypothesis of daily targeting and the intertemporal substitution hypothesis. The hypothesis of daily targeting is based on determination of income which workers try to achieve. On the other hand, the intertemporal substitution hypotesis assumes that hours worked depend on wage rate. I have used the survey to obtain monthly data of work hours and earned wage by Czech entrepreneurs. Based on the obtained data I have tested two hypotheses. Wage elasticities have positive values which lead to rejection the hypothesis of daily targeting. I have offered several possible explanations of obtained conclusions. One of them is the focus of entrepreneurs on accumulation of capital and wealth as the main motivation for business. This is related to recent economic transition in the Czech Republic.

Společný jazyk matematiky a ekonomie
HOŠEK, Radim
This bachelor thesis emanates from the paradox that undergraduate students of economics are given a number of mathematical courses that endow them with powerful tools, which are not afterwards used in the courses of economics and finance. The goal of this thesis is to provide a supplementary explanation of some of these topics, using various mathematical tools that are contained in the standard courses. Special attention is given to the problematics of graphical representation in economics, as in many cases there is a tendency to disobey the standard convention of using the horizontal axis for the independent variable. For some topics an alternative graphical visualisation is supplied while we show that it is not always useful. We investigate the issue of summing the curves and offer an explanation, how the information can be obtained from the graphs that do not obey the above mentioned convention.
