The results are presented in Table I.A1.1. This is less than the 13% found by Topel (1999), but at the higher end of the range of results in Bassanini and Scarpetta (2002). The 10% rise in per capita output is not surprising since coverage encompasses a longer time period and a higher number of countries, including those where there was more pronounced growth in both educational attainment and output per capita.
