📢 NEW PAPER!
Do teachers recognize stereotypes in the classroom? We introduce the Stereotype Identification Test (SIT) to measure this ability and explore whether it can be improved.

6/6 Illicit trade in cultural goods affects not just markets, but identity & heritage. Our paper shows how trade data can reveal these hidden flows—and why better cooperation is essential. Looking forward to your comments!

5/6 Policy takeaways:
♦️ Legal frameworks alone are insufficient!
♦️UNIDROIT 1995 is more effective than UNESCO 1970—but major markets (US, UK) haven’t ratified.
Enforcement capacity + international cooperation are crucial.

4/6 Findings:
☑️Gaps grow with interest in Italian culture 📈
☑️Stronger corruption control reduces gaps in regulated markets (sculptures, antiques)
☑️Archaeological property: post-2010 spike → linked to Arab Spring looting

3/6 🔎 Our contributions:
1️⃣ A new Cultural Salience Index (Google Trends data) to capture demand for Italian culture.
2️⃣ Gravity model of trade gaps, linking them to GDP, distance, corruption, and salience.
3️⃣ Assessment of UNESCO 1970 & UNIDROIT 1995 conventions.

8/ Low-cost information interventions work, BUT messaging must be context-sensitive: Private narratives foster personal responsibility, public narratives risk backfiring when trust in institutions is low or public provision is seen as sufficient. docs.iza.org/dp18054.pdf

7/ Geographic differences: 🌍 In post-communist countries, public & neutral framings lower donations—likely reflecting lower institutional trust & weaker private giving norms.

6/ Heterogeneity matters: 🔹 Stronger effects among those with lived experience or high concern. 🔹 But when people perceive public provision as adequate, collective framings reduce private contributions → a substitution effect.

docs.iza.org

Marina Della Giusta @mardelgiu.bsky.social · Aug 26

5/ Stigma reduction emerges as a key mechanism: 🧠 All framings significantly reduce mental health stigma. This partly explains higher donations, especially under public framing.

docs.iza.org

Marina Della Giusta @mardelgiu.bsky.social · Aug 26

4/ Main findings: ✅ All three mental health framings significantly increase cooperation & donations vs. control. ✅ People act even without expecting others to do the same → intrinsic motivation matters!

docs.iza.org

3/ After exposure, participants made real-money decisions:
A Public Goods Game → cooperation measured via contributions.
A Charity Dictator Game → donations to mental health & other causes.

2/ Participants were randomly exposed to one of three framings:
🔹 Private → individual benefits of investing in mental health
🔹 Public → collective benefits for society
🔹 Neutral → prevalence facts only

1/ Mental health is key for well-being & productivity, yet investment remains chronically low. We ran a pre-registered online experiment (N = 8,312) in 🇫🇷 🇩🇪 🇮🇹 🇪🇸 🇸🇪 🇱🇻 🇸🇰 to test how different framings affect citizens’ willingness to act.

🚫 The link with drug use is positive but less robust.
✅ Strongest risky behaviour links: alcohol and early sexual activity. Policy implication:
Social media is not just a passive activity—it may be a risky behaviour in itself for adolescents.

Marina Della Giusta @mardelgiu.bsky.social · Aug 2

6/
Early puberty matters: it’s associated with higher risk-taking in adolescence.
Our mediation analysis shows:
Earlier menarche partially explains increases in smoking, drinking, and early sexual initiation among heavy users.

Marina Della Giusta @mardelgiu.bsky.social · Aug 2

5/
We find both direct and indirect effects:
➡️Direct: intensive social media use accelerates menarche.
⏩Indirect: poorer mental health mediates part of the effect.

Marina Della Giusta @mardelgiu.bsky.social · Aug 2

4/
Why? Our evidence points to stress and mental health deterioration as a likely mechanism.
Heavy social media use → more stress/anxiety → earlier puberty onset.
This aligns with medical literature linking stress to earlier menarche.

Marina Della Giusta @mardelgiu.bsky.social · Aug 2

3/💡 Key finding: Girls who use social media intensively at age 11 are more likely to experience earlier menarche. ➡️ Effect size: +2–4 percentage points in probability of starting menstruation earlier. No clear effect for boys' puberty markers.

Marina Della Giusta @mardelgiu.bsky.social · Aug 2

2/ We use data from the Millennium Cohort Study tracking ~19,000 UK 🇬🇧children from birth to age 17 and link social media use at ages 11, 14, and 17 with puberty markers and risky behaviours.

📢 Relevance for policy- Our model can simulate effects of:
✅ Legalizing or criminalizing sex work
✅Digital sex tech
✅Educational interventions on relational skills
✅Shifts in gender norms and wages

🧠 We contribute a unified rational choice framework that:
🔬Encompasses paid sex and marriage
🔬Explains segregation in sex markets
🔬Models sexual activity and fertility as time allocations
🔬Endogenizes gendered outcomes via norms and human capital

👩‍🎓 Implications for gender and education:
Gender norms shape relational skill acquisition.
This explains gendered occupational sorting—including into sex work—and has implications for labor markets, fertility, and policy.
