"We develop a method for decomposing countries' observed export prices into quality versus quality-adjusted-price components using information contained in their trade balances. Holding observed export prices constant, countries with surpluses are inferred to offer higher quality than countries...

"We estimate the effect of factor proportions on the pattern of manufacturing specialization in a cross-section of OECD countries, taking into account that factor accumulation responds to productivity. We show that the failure to control for productivity differences produces biased estimates....

We develop a model of international trade with export quality requirements and two dimensions of firm heterogeneity. In addition to "productivity", firms are also heterogeneous in their "caliber" -- the ability to produce quality using fewer fixed inputs. Compared to single-attribute models of...
