    We investigate the impact of public procurement on business survival. Using Italy as a laboratory, we construct a large-scale dataset of firms—covering balance-sheet, income-statement, and administrative records—and match it with public contract data. Employing a regression discontinuity design for close-call auctions, we find that winners are more likely to stay in the market than marginal losers after the award and that the boost in survival chances lasts longer than the contract duration. We document that this effect is associated with earnings substitution rather than increased business scale and that survivors experience no productivity premium. Securing contracts relaxes credit constraints and acts as a mechanism for survival.

    We investigate the impact of public procurement spending on business survival. Using Italy as a laboratory, we construct a large-scale dataset on firms-covering balance-sheet, income-statement, and administrative records-and match it with public contract data. Employing a regression discontinuity design for close-call procurement auctions, we find that winners are more likely to stay in the market than marginal losers after the award and that the boost in survival chances lasts longer than the contract duration. We document that this effect is associated with earnings substitution rather than increased business scale. Regardless of size, contracts that are long-lasting and awarded by decentralized buyers are more impactful for survival prospects. Survivors experience no productivity premium but rather an improvement in their credit position.

    We empirically investigate the effect of procurement oversight on contract outcomes. In particular, we stress a distinction between public and private oversight: the former is a set of bureaucratic checks enacted by contracting offices, while the latter is carried out by private insurance companies whose money is at stake through the so-called performance bonding. By focusing on the U.S. federal service contracts in the period 2005-2015, we exploit an exogenous variation in the threshold for the application of both sources of oversight in order to separately estimate their causal e effects on execution costs and time. We find that: (i) private oversight has a positive effect on outcomes through the screening of bidders that alters the pool of winning firms; (ii) public oversight negatively affects outcomes, due to excessive red tape induced by low-competence buyers.

    This paper investigates the factors that contributed to the proliferation of online COVID skepticism on Twitter across Italian municipalities. We demonstrate that socio-demographic factors are likely to mitigate the emergence of skepticism, while populist political leanings were more likely to foster it. Furthermore, we find that the presence of pre-COVID anti-vax sentiment, represented by old "truthers" on Twitter, amplifies online COVID skepticism in local communities. Additionally, exploiting the spatial variation in economic restrictive policies with severe implications for suspended workers belonging to non-essential economic sectors, we find that COVID skepticism spreads more in municipalities significantly affected by this economic lockdown. Finally, the diffusion of COVID skepticism is positively associated with COVID vaccine hesitancy.

    This paper quantifies the impact of online vaccine skepticism on pediatric vaccine uptake, vaccine-preventable hospitalizations, and their related costs. We propose an instrumental variable strategy that leverages the complex structure of social networks. By matching Italian vaccine-related tweets for 2013-2018 with vaccine coverage and preventable hospitalizations data, we find that a 10pp increase in anti-vaccine sentiment causes a 0.43pp decrease in Measles-Mumps-Rubella vaccine coverage. This shift results in an additional 2.1 hospitalizations per 100,000 residents and an 11% increase in relevant healthcare expenses. Conversely, we find no statistically significant impact on vaccines not targeted by online misinformation (e.g., Hexavalent, Meningococcal, Pneumococcal). The results of a simulated model further suggest that informative campaigns are the most effective method to mitigate the effects of online misinformation and reduce polarization.

    This paper quantifies the impact of online vaccine skepticism on pediatric vaccine uptake and health outcomes. We propose a novel methodology that combines Natural Language Processing and an instrumental variable strategy that leverages the intransitivity of the social network's connections. By matching the universe of Italian vaccine-related tweets for 2013-2018 with vaccine coverage and preventable hospitalizations at the municipality level, we find that a 10pp increase in anti-vaccine sentiment causes i) a 0.43pp decrease in coverage of the Measles-Mumps-Rubella vaccine, ii) additional 2.1 hospitalizations among vulnerable populations per 100,000 residents, and iii) an 11% increase in the relevant healthcare expenses, equivalent to 7,311 euros. Drawing on the results of a simulated model, we further show the importance of targeted interventions to counter misinformation and improve vaccine uptake.
