In particular, it aims at studying channels through which financial transaction taxes on equity trading are directly and indirectly passed on to investors of funds investing in such taxed markets as well as changes in the investment behavior of these funds. This project makes use of detailed investment vehicle-level data and quasi-experimental methods to identify such consequences of financial transaction taxes. Thereby, it intends to provide a stronger empirical foundation for the ongoing debate on the introduction of financial transaction taxes
