Podatek od transakcji finansowych jako narzędzie oddziaływania na rynek finansowy

The financial crisis, which affected financial markets at the end of the first decade of the 21st century, and the resulting reactions of state governments, aimed at the increased regulation of the financial market, revived the debate on the introduction of one of the possible tools for such regulations in the European Union, i.e. the financial transaction tax - FTT. The article discusses the main non-fiscal objectives imposed on such tax, both from the theoretical and empirical perspective. The theoretical arguments justify the introduction of FTT, however, the results of empirical studies are inconclusive regarding the tax consequences, particularly in terms of its non-fiscal goals.
