In this paper, I empirically examine the non-monotonic relationship between openness and within-group wage inequality predicted by  Helpman et al. (2010) using a panel data for the US, 1983–2005. Within-group wage inequality is measured for each industry and matched with exports. It can be...

Combining Balassa–Samuelson effects with strategic complementarities between prices of tradables and non-tradables yields a novel determinant of tradables’ prices. A larger productivity difference between tradables and non-tradables raises the non-tradables’ price. With strategic...

We examine learning-by-exporting effects of manufacturing and services firms in 19 sub-Saharan African countries. Comparing several outlier-robust estimators, our results provide evidence for positive effects in the manufacturing sector when using the MM estimator, but not in the services sector.

Constant unit manufacturing costs are lower (higher) in high wage North when inputs are (i) tradeable, (ii) country-specific and (iii) the elasticity of substitution between them is below (above) one. A two-country model of firm entry/location is considered.
