摘要 / Abstract
Thispaper estimates product quality at the sectoral level using data from a panelof twelve manufacturing sectors in nineteen OECD countries during the years1995–2006. The author first derives a gravity model from a firm-heterogeneitymodel of trade, then measures product quality as the residual of the gravitymodel. In estimating the gravity model, the author employs the two-stepprocedure of Helpman et al. (2008) to correct for biases caused by selection intrade and firm heterogeneity. When aggregated into the country level, the usedoverall quality metrics do not systematically differ from Hallak and Schott’s(2011). In line with existing literature, sectoral quality estimates are foundpositively correlated with sectoral unit prices as well as countries’ incomeper capita. And the quality gap between rich and poor countries is morepronounced in capital- and skill-intensive sectors. In addition, the autorfinds beta- and sigma-convergence in sectoral product quality across countries.
