Abstract

In this paper, we study the cointegrating space spanned by Italian regional relative prices and per capita GDPs. To this end, we combine panel data with vector error correction model estimation in an innovative approach which is still under development. The results are interesting: regional prices, which seem to persistently deviate from the law of one price (PPP), cointegrate with relative per capita GDPs. The estimated elasticity is not consistent with the Balassa–Samuelson hypothesis but is closer to supporting the classical supply-demand schedule. Weak-causality testing gives further details on linkages between the real and nominal side of Italy’s regionally diversified economy. Homogeneity of the coefficients, lacking at a national level, can be recovered at a more disaggregated macro-area level.
