The project aims ot establish an index to measure trade-deflection of both inbound and outbound EU trade and to compare the index with standard measures in the intra-industry-trade debate. The intra-industry trade is measured by the well known Grübel-Lloyd index, for which we earlier developed a simplified version, the A.N.N.E. index for the EU as a whole and each of its member states (across product classes). The newly developed G.A.T.E. index follows a similar procedure and measures trade deflection for the EU as a whole and each of the product classes (across the member states). Both parameters feature a similar span but they may differ for specific product-country combinations. Those asymmetries allow to locate forms of trade-deflection and to specify them across industrial activities. This evidence is not new in free-trade areas which are NOT a customs union, but they may provide unique evidence in customs unions, such as the E.U., and, eventually, add evidence in in the 'fair trade' debate (e.g. free riding, regional development, etc.).
