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

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.

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

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.

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.
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.
