Tax competition is much discussed in the political arena these days. Although it is not a new phenomenon, the political pressure has increased to restrict tax competition by intensifying tax coordination and accomplishing tax harmonization. This particularly holds for the EU which has established a Code of Conduct for business taxation in 1997 and is about to establish a system of information exchange with respect to capital income taxation (allowing Austria, Belgium and Luxembourg a minimum source tax on capital income as an alternative). In 2001, the Commission has additionally released the so called Ruding II-report in which a uniform corporate tax base with formulary apportionment is proposed for the EU. In addition, the OECD (1998) aims at stronger tax coordination among its members also favoring a system of information exchange. Such a system would necessarily involve the abolishment of (or the reduction of the strictness of) bank secrecy laws around the world (Feld 2002).
