Fui ler o paper do NBER que tá sacudindo Singapura. Pesquisadores de Stanford e Columbia usaram IA pra varrer TODAS as transações imobiliárias do país entre 1995 e 2019 e cruzaram com o cadastro de 141 mil servidores públicos.
Funcionários compravam imóveis perto de futuras estações de metrô 1-2 anos ANTES do anúncio oficial. 60% acima da taxa normal. Não pagavam mais caro na compra, mas revendiam com retorno de 12% ao ano. Os parentes faziam a mesma coisa. S$270 milhões no total.
Pra descartar que fossem só mais espertos, compararam com corretores de imóveis e diretores de empresa. Nenhum dos dois mostrou o mesmo padrão. Rodaram 1.000 simulações aleatórias e o efeito real ficou totalmente fora da distribuição.
Quem mais operava? Gerentes médios do planejamento de transporte. Cargo suficiente pra saber, baixo o bastante pra ninguém olhar.
Em 2012, Singapura apertou a fiscalização com novas leis e punição de casos de alto escalão. O padrão sumiu, dos funcionários e dos parentes.
Singapura é top 5 em transparência no mundo. Norma social sozinha não segurou.

Senang sekali melihat paper luar biasa Naila Maya Shofia (NUS) tentang fenomena hijab di Indonesia dg menganalisa sekitar 250 ribu foto dari buku induk sekolah dari 2 dekade dan Sakernas, muncul di top journal. Congrats @NailaShofia1 !
250,000+ hand-coded student photos reveal how religious veiling in Indonesia evolved alongside changing economic opportunities for women and social norms.

Amazing report.
Kalau kamu wartawan, akademisi, aktivis, peneliti, atau warga sipil biasa yg lagi pantau isu kopdes di sekitar tempat kamu tinggal, kamu harus baca laporan ini.
Bahan utama reportase ini 82 juta basis data internal kopdes itu sendiri. Ada banyak temuan dan dataset menarik yg bisa kamu follow up. Bacanya sambil nyanyi dan berjoget ria ya! 💃🎤

France does it differently when it comes to school lunches. 🇫🇷
In France, the school canteen (la cantine) isn't just a place to grab a quick bite, it is viewed as an extension of education. Lunchtime is designed to teach children food culture, nutrition, and palate appreciation through freshly prepared, multi course meals. By law, these traditional four course menus (starter, main meal, cheese, and dessert) must regularly incorporate organic and locally sourced ingredients under strict nutritional standards.
Serving dishes like moules frites (steamed mussels with herbs and crispy fries) introduces kids to fresh seafood, complex flavors, and local culinary traditions from an early age, building a lifelong appreciation for real gastronomy. This footage was filmed at a public elementary school in the Haute Savoie region, where around 500 students aged 6 to 11 enjoy freshly prepared meals like this.

Today I've put up my 10th annual blog on development journals, where I work with editors to put together submission numbers, acceptance rates, review times, journal rankings, and more. More than 16,000 papers were submitted to 14 journals in 2025, and over 1,000 published 1/5

Excited to FINALLY release toughest+most rewarding paper I've worked on...
….we attack a 150 year old Walras question that's gone unanswered, not for lack of trying (Hicks, Samuelson, Arrow; our chances?😱)...
Q: Is the market equilibrium stable or unstable?¯\_(ツ)_/¯

Accepted manuscript now out in JEEA. Link here: doi.org/10.1093/jeea/jvag024
In an RCT across 400 high-migration villages, we shared simple “report cards” and other materials that made agency quality more transparent. These tools were designed to support women as they navigate a complex migration system where trustworthy information is often scarce.

We study the impact of e-money on cash demand in Indonesia. E-money adoption is associated with lower cash demand. Moreover, the effect is heterogeneous across regions and denominations.
Happy reading!
