The Dynamics and Spillovers of Management Interventions: Evidence from the Training Within Industry Program (with Michela Giorcelli)
​Accepted, Journal of Political Economy
Link
This paper examines the long-term and spillover effects of management interventions on firm performance. Under the Training Within Industry (TWI) program, the U.S. government provided management training to firms involved in war production between 1940 and 1945. Using a newly collected panel dataset on all 11,575 U.S. firms that applied to the program, we find that the TWI training had positive and long-lasting effects on firm performance and the adoption of beneficial managerial practices. Moreover, it generated complementarities among different types of training and had positive spillover effects on the supply chain of trained firms.

The Indirect Effects of Educational Expansions: Evidence from a Large Enrollment Increase in University Majors
Journal of Labor Economics, 38 (3): 767-804, 2020
Working paper, Published version
Increasing access to education may have consequences that go beyond the effects on marginal students encouraged to enroll. It may change peer effects, school quality, and returns to skill. This paper studies how classmates and teaching inputs affect learning of university students, exploiting an educational expansion in Italian STEM majors. Newly-collected data on 27,236 students indicate that less-prepared classmates and congestion of teaching resources lowered learning of incumbent students in STEM fields. Their learning, however, increased in courses in which the new classmates raised average preparedness. These effects might have had long-lasting consequences on the returns to STEM degrees.

Scientific Education and Innovation: From Technical Diplomas to University STEM Degrees. (with Michela Giorcelli)
Journal of the European Economic Association​, 18 (5): 2608–2646, 2020
Working paper, Published version
This paper uses a change in enrollment requirements in Italian STEM majors to study the effects of university STEM education on innovation and labor market outcomes. University-level scientific education had two direct effects on patenting of students who acquired a STEM degree thanks to the policy. First, it changed the direction of their innovation. Second, it moved these individuals closer to the innovation processes by allowing them to reach top positions within firms' hierarchies. STEM degrees, however, also changed occupational sorting. Some higher-achieving individuals used STEM degrees to enter jobs that required university-level education, but did not focus on patenting.

Compulsory Licensing and Innovation. Historical Evidence From German Patents After WWI. (with Petra Moser and Joerg Baten)
Journal of Development Economics, 126: 231-242, 2017
Working paper, Published version
Compulsory licensing allows governments to license patented inventions without the consent of patent owners. Intended to mitigate the potential welfare losses from enforcing foreign-owned patents, many developing countries use this policy to improve access to drugs that are covered by foreign-owned patents. The effects of compulsory licensing on access to new drugs, however, are theoretically ambiguous: Compulsory licensing may encourage innovation by increasing competition or discourage innovation by reducing expected returns to R&D. Empirical evidence is rare, primarily because contemporary settings offer little exogenous variation in compulsory licensing. We address this empirical challenge by exploiting an event of compulsory licensing as a result of World War I when the US Trading with the Enemy Act made all German-owned patents available for licensing to US firms. Firm-level data on German patents indicate that compulsory licensing was associated with a 30 percent increase in invention by German firms whose inventions were licensed.

Career Spillovers in Internal Labor Markets  (with Giulia Bovini, Jin Li, Matteo Paradisi, and Michael Powell)
Revise and resubmit, Review of Economic Studies
Link
This paper studies career spillovers across workers, which arise in firms with limited promotion opportunities. We exploit a 2011 Italian pension reform that unexpectedly tightened eligibility criteria for the public pension, leading to sudden, substantial, and heterogeneous retirement delays. We use administrative data on Italian private-sector workers and leverage cross-firm variation to isolate the effect of retirement delays among soon-to-retire workers on the wage growth and promotions of their colleagues. We find evidence of spillover patterns consistent with older workers blocking the careers of their younger colleagues. These effects are present only in firms with limited promotion opportunities.

The Effects of Fiscal Decentralization on Publicly Provided Services and Labor Markets (with Michela Giorcelli and Enrica Maria Martino)
Revise and resubmit, Economic Journal
Link
This paper studies how fiscal decentralization affects the provision of local services. It exploits a 1993 reform that increased the fiscal autonomy of Italian municipalities by replacing government transfers with revenues from a new local property tax. The identification leverages cross-municipal variation in the degree of decentralization that stems from Allied bombings during WWII. Decentralization reduced overall spending but expanded municipal services, such as nursery schools. These effects are larger in areas with higher political competition. The paper also investigates how the reform affected the labor markets. Decentralization, likely through expanded nursery schools, increased female labor supply, reducing the gender gap in employment.

The Effects of Computer-Assisted Learning on Students' Long-Term Development (with Yi Lu and Hong Song)
Link
In this paper, we examine the effect of computer-assisted learning on students’ long-term development. We explore the implementation of the “largest ed-tech intervention in the world to date,” which connected China’s best teachers to more than 100 million rural students through satellite internet. We find evidence that exposure to the program improved students’ academic achievement, labor performance, and computer usage. We observe these effects up to ten years after program implementation. These findings indicate that education technology can have long-lasting positive effects on a variety of outcomes and can be effective in reducing the rural–urban education gap.

Reconstruction Aid, Public Infrastructure, and Economic Development: The Case of the Marshall Plan in Italy (with Michela Giorcelli)
Revise and resubmit, Journal of Economic History
Link
The Marshall Plan (1948–1952) was the largest aid transfer in history. This paper estimates its effects on Italy's postwar local economic development. It exploits plausibly exogenous differences between Italian provinces in the value of reconstruction grants they received. Provinces that could modernize a larger portion of their infrastructure stock experienced higher increases in agricultural production, especially for perishable crops that benefited the most from an efficient transportation system. In the same provinces, we observe larger investments in labor-saving machines, the entry of more firms into the industrial sector, and a larger expansion of the industrial and service workforce.

Countries for Old Men: An Analysis of the Age Wage Gap (with Matteo Paradisi)
Link (please email me if you are interested in reading the most recent draft)
In the last three decades, the wages of older workers in many high-income countries grew at a much faster rate than the wages of younger workers. This paper uses extensive administrative data from Italy and Germany to provide an analysis of this age wage gap. First, the widening of the age wage gap stemmed from the increasing difficulty of younger workers to reach high-paying jobs. Second, a large part of the deterioration in the careers of younger workers occurred within firms. Third, different appropriation of firm-specific rents can explain more than half of the widening in the age wage gap. The last portion of the analysis shows that the effects are larger for firms with constraints in adding higher-ranked jobs to their organization, highlighting the role of career spillovers in widening the age wage gap.
