Harmful norms persist because, in many places, they serve a socially valued function. But what happens when that function loses its value? Our new paper studies this through the case of female genital mutilation (FGM) in Nigeria. With @danielperezpa & @RiccardoCiacci Thread🧵

1/ Este pobre hombre dice cero (0) veces las palabras “cristiano” o “musulmán”. Y describe un ataque de ganaderos fulani a una comunidad agricultora. Los voceros del “genocidio cristiano” intentan encajar su sesgo; sabemos que les da igual que maten a un agricultor a secas.
Nigerian Christians: "Every house was set ablaze and all our grains were burnt down....This morning we buried 29 people" The world is silent.

La izquierda en España debe encontrar un camino para emanciparse de estas ideas. El estancamiento de los salarios reales no se explica porque "los ricos se forren", sino por problemas estructurales: baja productividad, falta de competencia, regulación ineficiente, y un modelo

Creative destruction is also the most under-appreciated reason for why high minimum wages can improve economic efficiency
The 2025 laureates in economic sciences Philippe Aghion and Peter Howitt studied the mechanisms behind sustained growth. In an article from 1992, they constructed a mathematical model for what is called creative destruction: when a new and better product enters the market, the

Las política de visados de Trump está descapitalizando las universidades americanas. Oportunidad de oro para atraer talento que me temo perderán las universidades públicas españolas por su rigidez, falta de financiación y apuesta por la excelencia, y cultura del "café para todos"

Hablan de ‘genocidio’ en Nigeria, cuando ni los propios cristianos nigerianos lo describen así: se trata, en esencia, de un conflicto agro-pastoral entre nómadas y comunidades sedentarias. Ejemplo de mover la portería para evitar condenar un genocidio real.
Lo de los cristianos en África sí que es un genocidio

En esta carta se comparan 8 millones de euros en gastos por desplazamientos de los Diputados con 218.000 millones de euros de gasto en pensiones (estimación 2025). Es una relación de 27.000 a 1 o, como gusta contarlo, 19 minutos de pensiones.

I find it strange to be against wealth taxes on efficiency grounds. Tax theory largely finds that wealth taxes are among the least distortionary taxes we have.
In my view, economists should analyze tax policy based on incentives, not moral sentiments, where we have little comparative advantage. The wealthy may not "deserve" their comfort, but strangely confiscating the rewards to private success seems always to produce misery for the

If modest pensions can measurably reduce the practice of old kinship systems (e.g., adult children residing with their parents), perhaps the impact of economic development on cultural change (as opposed to the reverse) is severely underrated... Also, there is a

@Ice_Landic @ElDiscursista La TIR media de las pensiones en España ahora mismo es 5,7% (cálculo de la AIReF). No hay inversión en activos del sector privado que dé esa rentabilidad con el mismo nivel de riesgo que la Seguridad Social (con revalorización asegurada por IPC y valor vitalicio). Una cartera
