By roughly the five-year mark after the launch of the euro in 1999, enough data had accumulated to allow an analysis of the early effects of the euro on European trade patterns. Studies include Micco, Ordoñez and Stein (2003), Bun and Klaassen (2002), Flam and Nordström (2006), Berger and Nitsch (2005), De Nardis and Vicarelli (2003, 2008), and Chintrakarn (2008). The general finding was that bilateral trade among euro members had indeed increased significantly, but that the effect was far less than the one that had earlier been estimated by Rose and others on the larger data set of smaller countries. Overall, the central tendency of these estimates seems to be a trade effect in the first few years on the order of 10-15%. None came anywhere near the tripling estimates of Rose (2000), or the doubling estimates (in a time series context) of Glick and Rose (2002). read more
