As the bloc’s third-biggest economy, Italy needs to pick up its pace, and that can only happen if the long-benighted South contributes too. While the gap with Northern Italy remains substantial by measures including unemployment, per-capita income and population, the economy of the Campania region, where Naples is located, grew 0.9% last year, outstripping the 0.7% in Milan’s province of Lombardy and well ahead of the 0.5% national average, according to Bank of Italy data.
