Drivers of productivity differentials between southern and northern manufacturing in Italy: technical inefficiencies or allocative distortions?

This paper estimates regional economic efficiency differentials at the firm level in the Italian manufacturing sector over the period 1998-2003. We implement an input distance function approach providing measures of both technical inefficiency and allocative distortions in the choice of input mixes. Our results confirm the substantial technical efficiency gap suffered by firms located in Southern regions, thus providing empirical support to the “structural and technological gap” interpretation of the Italian dualism. On the other hand, allocative distortions in the use of inputs show less remarkable regional differences. As for policy implications, our results suggest the need for a re-allocation of public resources for development policies from business incentives measures towards public investments
