Comparison of negative income tax models
Havlíková, Iveta ; Stroukal, Dominik (advisor) ; Brožová, Dagmar (referee)
We are comparing the economic models of state social support which utilize the concept of the negative income tax. The comparison builds upon the overview of the main theoretical articles. We have analysed the proposals of various political parties regarding the negative income tax; in case of a Czech party's proposal of replacing a set of subsidies with the negative income tax, we have calculated the overall expected savings. For the purpose of the overall comparison, we selected the models of Friedman, Tobin, Sulik and the Earned Income tax Credit model. We benchmarked them in various theoretical and practical criteria. We conclude that they do not differ substantially except for their philosophical interpretation.

How bussiness cycles infuence property crime?
Havlíková, Iveta ; Lahvička, Jiří (advisor) ; Babin, Jan (referee)
This thesis aims to look into a relationship between business cycles, which are represented by unemployment, and property crime. I used daily data for years 2005-2010 from Prague. Models for seven different types of crimes (Pickpockets, pilfering of motor vehicle, car theft, pilfering of shops, pilfering of restaurants and two kinds of burglaries,(flats, houses) were used to help to examine this relationship. Positive impact of unemployment on property crime was not proven. On contrary there is negative and signifficant effect of unemployment on car thefts and pilfering of shops. One percentage point growth of unemployment causes decrese of car theft by 1,2 cars for one milion inhabitants per day and by 0,32 shops for one milion inhabitants per day. Also a negative impact of state holiday and different impact of climate contitions were proven.
