I am a Postdoctoral Researcher in the Department of Economics at the University of Bologna. I received my PhD from the University of Turin and Collegio Carlo Alberto in 2023.
My research focuses on economic history, political economy, and long-term economic development. I use original historical data to study the long-term effects of shocks, culture, and conflict.

Planting the Seeds of Polarization: Sharecropping, Agrarian Conflict and Enduring Political Divides (with Paolo Buonanno). Submitted
This paper shows how enduring agrarian institutions shaped the long-run political consequences of historical shocks. We study Italy’s sharecropping system (mezzadria)—a centuries-old fifty–fifty contract that structured rural relations across central Italy—and link its prewar prevalence to Socialist and Communist voting from 1913 to 1948. Using harmonized data for 720 agrarian zones and a combination of cross-sectional, entropy-balanced, and spatial RDD designs, we find that sharecropping was politically neutral before World War I but became a center of rural unrest and Fascist repression afterward. Areas with more sharecroppers experienced greater strike activity, targeted violence, and enduring left alignment. A daily panel of 1921 events shows repression peaking during annual contract renewals. The results reveal a “revolt–repression–realignment” mechanism through which local economic institutions converted wartime shocks into lasting partisan divides.
When we rebel? clashing narratives and the making of subversive identities (with Matteo Cervellati, Elena Esposito and Alessandro Saia).
Individuals sometimes take extraordinary personal risks to resist and fight oppressive regimes. Material incentives alone fail to fully explain these life-threatening decisions, which appear to be largely driven by a profound sense of injustice and strong emotional motivations. This paper provides evidence of the significant role that immaterial incentives play in motivating rebellion, by examining the formation of subversive identities in Italy following World War I. We reconstruct the history of Italian families, tracing patterns of dissent and rebellion from the early 20th century through World War II. Using these novel data, we examine how a government propaganda campaign—the passage of the train carrying the Unknown Soldier—interacted with personal histories of grievance and loss, fostering the formation of subversive identities and increasing the likelihood of rebellion against the rising Fascist regime. Looking at individual participation in the armed resistance in WWII, we next isolate the longer-term role of the post-WWI propaganda campaign, the emergence of oppositional identities within families, and the role of early political dissenters in catalyzing the armed fight that put an end to the dictatorship.

Monarchy vs Republic: Historical Evidence on Individual Preferences and their Roots (with Matteo Cervellati and Sara Lazzaroni). [Draft coming soon]
In a unprecedented and still unique instance of self-determination in nation building, the institutional form of the state at the moment of democratization in 1946 Italy has been chosen with a referendum held in universal franchise. The vote involved around 25 million people with all women and a large majority of men voting for the very first time. The referendum offers a unique opportunity to study individual preferences over democratic institutions in the population at large at the moment of democratization. We study how the exposure to republican and monarchic rule in historical times shaped individual preferences for free institutions during democratization. We provide a measurement of political history over the 1000–1861 time period for around 8,000 municipalities. Evidence shows that higher intensity of exposure to republican, respectively monarchic, rule in the past is a main determinant of the vote. Alternative identification strategies and checks, including the use of local variation, IV and spatial RDD strategies, bolster a causal interpretation of the findings. Large effort is devoted to validation and mechanisms. Accounting for conditions in 1946 confirms the role of political history and documents that socio-economic conditions at the moment of the vote (inequality, education and sectoral employment), experience of nazi-fascist massacres, war violence, and exposure to radio propaganda also matter. For both validation and mechanism, we assemble a database on historical local statutes in pre-industrial times. Within municipality panel variation show that political history in quarter-centuries leads to the emergence of charters granting freedom and self-governance. Finally, we look at large scale surveys, to study the impact on the support for democracy and trust in political institutions half a century after democratization.
