Wpływ podatku od niektórych instytucji finansowych na wartość rynkową banków komercyjnych w Polsce

Abstract: Purpose – investigate the impact of introducing bank tax on the market value of commercial banks in Poland as well as tax assessment from the point of view of the prerequisites for introduction. Design/Methodology/approach – an event study methodology was used to empirically examine stock market reaction to the introduction of bank tax in Poland. Findings – The stock market reacted positively to the introduction of bank tax. This is probably due to the fact that investors are convinced that banks will be able to pass on costs to customers. Originality/value – The use of event analysis in assessing the introduction of a banking tax in Poland is probably the first one, which is likely due to the fact that another very important event occurred in the period under consideration whose impact is difficult to isolate. Despite the aforementioned drawback the research conclusion is significant because both of these events should have a negative impact on the market value of the banks while the study results showing something quite the opposite.
