Abstract

The assumption that national labour markets are homogeneous across tradable and non-tradable goods is common in multisector (open-economy) macro models and crucial for the prominent Balassa–Samuelson hypothesis. To test it, this study introduces a novel, theory-based method of distinguishing the tradable and non-tradable sectors to the Balassa–Samuelson literature and employs modern empirical methods and a large and detailed macro dataset. It finds that both the internal relationship between productivity and wages in the tradable and non-tradable sectors postulated by the Balassa–Samuelson hypothesis and its external transmission mechanism are rejected.
