This paper analyzes the impact of public procurement contracts tendered by municipalities on the productivity. To this end, we combine firm-level information on Italian firms with administrative records on the universe of public procurement contracts in the period 2010-2018. We strengthen our analysis by using an instrumental variable approach that exploits the unexpected exemption of households from paying municipal property tax on their first homes, which occurred in Italy in 2008. Then we find that, ceteris paribus, a higher per capita value of public procurement contracts at the municipal level leads to higher productivity. In addition, the positive relationship between procurement and productivity is significantly weakened for firms with dynastic top management, suggesting a potential misallocation of public resources, and a consequent negative impact on productivity.
