The article provides the results of microeconomic and macroeconomic analysis of the effects of immigration to Austria. The analysis results confirm that the influx of foreign workers contributes to the economic growth of the country. Special emphasis has been placed on the author’s attempt to analyse foreign participation in generating GDP in Austria, as foreign workers account for more than 10% of Austria’s hired labour force. The analysis has been enlarged by calculations concerning the ‘hidden economy’ as well as illegal immigration.plArtykuł
