11/ 🎯 The takeaway: States use surveillance as a preventive tool against the empowerment of educated but excluded groups. 👉 As excluded groups gain political empowerment, surveillance may reproduce inequalities by silencing them exactly as they gain political voice.
120
Gemma Dipoppa @gemmadipoppa.bsky.social · 24/11/2025
10/ Across democracy and dictatorship, and with more and less technology to collect data, the logic of surveillance was similar: States target those combining political capacity (education) with radical grievances (subalternity).
130
Gemma Dipoppa @gemmadipoppa.bsky.social · 24/11/2025
9/ ➡️ Result 3: Across 5 indicators of political activism—voting, protests, strikes, holding political roles, and armed resistance—educated cohorts did not become more engaged. Surveillance expanded preventively, not in reaction to mobilization.
120
Gemma Dipoppa @gemmadipoppa.bsky.social · 24/11/2025
8/ ➡️ Result 2: Who faced the brunt of surveillance? The working class. The newly educated poor were watched longer, more harshly, and more intensively, consistently with the state fearing their empowerment.
120
Gemma Dipoppa @gemmadipoppa.bsky.social · 24/11/2025
7/ The effect persists even when individuals move elsewhere, in line with surveillance following a portable asset (education) rather than municipal-level changes.
120
Gemma Dipoppa @gemmadipoppa.bsky.social · 24/11/2025
6/ We present 3 results: ➡️ Result 1: Municipality-cohorts exposed to more schooling were 64% more likely to be surveilled. The effect increases as the state expands education and disappears when later reforms equalize schooling across municipalities.
110
Gemma Dipoppa @gemmadipoppa.bsky.social · 24/11/2025
5/ 🎲 The shock: The Casati Law mandated primary schooling for 2 years everywhere but extended it for +2 years in towns >4,000 inhabitants and cohorts born post 1854. We show the reform reduced illiteracy and use it in a difference-in-discontinuity design by population and cohort.
110
Gemma Dipoppa @gemmadipoppa.bsky.social · 24/11/2025
4/ 📃 📄 Descriptively, educated people were more likely to be watched. But education may proxy for background, status, or other fixed attributes. We need a shock to education that affects otherwise similar people.
100
Gemma Dipoppa @gemmadipoppa.bsky.social · 24/11/2025
3/ Unsupervised LLM on 1,200+ police files shows that mobilization capacity – and a particular marker of it, education, – together with potential for subversion are recurring traits noted by the surveillance state. 📚
130
Gemma Dipoppa @gemmadipoppa.bsky.social · 24/11/2025
2/ 💡 We propose that states strategically target those combining capacity to mobilize with grievances for radical mobilization – educated but subaltern individuals perceived as most threatening to state stability. This idea is rooted in descriptive data:

🚨 New WP 🚨: All states monitor the political activity of their citizens. But who do they choose to surveil, and why? We study this question with the universe of Italian political surveillance files: 152,000 individuals born 1816–1932, across democracy and autocracy. 🧵 1/11

9/ If you’re interested in the intersection of migration, labor exploitation, and organized crime, check out the full paper here: 🔖 www.journals.uchicago.edu/doi/10.1086/...
120
Gemma Dipoppa @gemmadipoppa.bsky.social · 08/03/2025
8/ 🚨 Policy takeaway: Combating organized crime isn’t just about state strength. Reducing reliance on criminal intermediaries requires tackling the conditions that make their services valuable—like migrant labor precarity.
101
Gemma Dipoppa @gemmadipoppa.bsky.social · 08/03/2025
7/ 🌏 This has global implications. Similar dynamics could explain how the Italo-American mafia exploited migrant labor in early 20th-century NYC, or how Nigerian gangs control undocumented migrants in Italy today.
100
Gemma Dipoppa @gemmadipoppa.bsky.social · 08/03/2025
6/ 💡Key insight: Mafias don’t just replace weak states. They complement strong states by enabling illegal activity that would otherwise be too risky. Organized crime should be reconceptualized as both a substitute for weak states and a tool for rule evasion in strong ones.
100
Gemma Dipoppa @gemmadipoppa.bsky.social · 08/03/2025
5/ Using a discontinuous shock affecting constructions and a shift-share instrument, I show that mafia presence increased where: ✅ Construction boomed (creating demand for unskilled labor) ✅ Migration from Southern Italy surged (providing a labor supply mafias could control)
100
Gemma Dipoppa @gemmadipoppa.bsky.social · 08/03/2025
4/ I test this using a novel dataset tracking mafia expansion from the 1960s onward. By scraping historical newspapers and validating with judicial data, I create the first municipal-level, time-varying measure of mafia presence in Italy. 📰
100
Gemma Dipoppa @gemmadipoppa.bsky.social · 08/03/2025
3/ In Northern Italy, mafias expanded where firms needed cheap, informal labor. They supplied it by controlling migrant workers from mafia-affected regions. This allowed local firms to evade labor laws without risk of denunciation.
