The economists discovered that following the appearance of the first data leak, which originated from LGT Bank in Liechtenstein, also Swiss banks engaged in cross-border tax evasion suffered significant drops in their share prices. At the same time, bank deposits in tax havens fell by more than ten percent compared to deposits in non-haven countries.
