چکیده
5 Using novel estimates of sectoral total factor productivities for 72 countries across 5 6 decades we provide evidence of relative productivity convergence: productivity grew 7 systematically faster in initially relatively less productive sectors. These changes have 8 had a significant impact on trade volumes and patterns, and a non-negligible welfare 9 impact. Had productivity in each country’s manufacturing sector relative to the US 10 remained the same as in the 1960s, trade volumes would be higher, cross-country 11 export patterns more dissimilar, and intra-industry trade lower than in the data. 12 Relative sectoral productivity convergence – holding average growth fixed – had a 13 modest negative welfare impact. 14 JEL Classifications: F11, F43, O33, O47 15 16
