Returns to Scale for EU Regional Manufacturing

Abstract

Recent theoretical advances have emphasised the importance of localised increasing returns to scale in understanding both the regional growth and agglomeration processes. However, considerable empirical controversy still exists over whether returns to scale are constant or increasing. Consequently, this study aims to provide some new estimates of the degree of returns to scale for EU regional manufacturing. It does so within the framework of the Verdoorn law. Unlike previous studies, issues of specification of fundamental importance to recent theoretical developments are brought to attention. Overall, the paper concludes that localised increasing returns in EU regional manufacturing are substantial.increasing returns, Verdoorn law, manufacturing, productivity growth, spatial econometrics
