type="main" xml:lang="en"> <title type="main">Abstract</title> <p>We consider the role of imperfect competition in explaining the relative price of non-traded to traded goods within the Balassa–Samuelson framework. Under imperfect competition in these two sectors, relative prices depend on both productivity and mark-up differentials. We test this hypothesis using a panel of sectors for 12 OECD countries. The empirical evidence suggests that relative price movements are well explained by productivity and mark-up differentials.
