Abstract: This paper estimates the socio-economic impact of infrastructure recovery investments and resilience plan related to the Institutional Development Contract (CIS) for the city of Taranto on different categories of households, labor markets (skilled and unskilled), and private enterprises in Italy. It does so by implementing a multi-regional input-output (MRIO) model with inter-regional trade at the level of Apulia region, to estimate the intra-regional impact, and, at the national level, to estimate the inter-regional and inter-sectoral supply chain linkages and spillover effects through trade. The intra-regional effects are almost two times the inter-regional effects. Almost 51% of the inter-regional impact on value-added accrues to northern regions, 22% at the centre, while about 27% is captured by the regions in southern Italy. This evidence clearly shows a good degree of connection of the Apulia local economy with the macro region of northern Italy, while it is quite weak with the macro south in Italy. The considerable share of inter-regional spillover effects in terms of value-added, which is transferred outside the southern macro-region, over 73% reflects the persisting regional disparities in Italy, where the productive northern-regions mostly benefit from the national development policies made in the most marginal areas in southern Italy.
