Tobin tax
The Tobin tax idea was the subject of much discussion in Europe in the summer of 2001. On June 15, 2004, the Commission of Finance and Budget in the Belgian Federal Parliament approved a bill implementing the Spahn tax (a version of the Tobin tax proposed by Paul-Bernd Spahn). According to the legislation, Belgium will introduce the Tobin tax once all countries of the eurozone introduce a similar law.
