Some of the macroeconomic effects of labour migration following the Czech Republic joining the European Union
Vystrčil, Tomáš ; Černý, Michal (advisor) ; Tomanová, Petra (referee)
When the Czech Republic joined the European Union in 2004, the number of foreign nationals working in the Czech Republic quickly grew, along with their impact on the national economy. The aim of this thesis is to analyse and compare the effects of foreign and native labour on the gross domestic product (GDP) of the Czech Republic. Then we shall compare the effects of immigrant labour originating from the EU with other foreign nationals. Using the ordinary least squares method to analyse time series data, it is shown that labour migration has a positive effect on the GDP growth and the results are statistically significant. It seems that labour from the EU is the most productive group, followed by the foreign labour from other countries.
