The social mirage: what we believe about our popularity and influence is mostly wrong. Understanding how we see ourselves within our social circles is more complicated than it seems. Although people interact daily with classmates, colleagues, and friends, our research shows that we have...

Our new PNAS paper, “Perception of Own Centrality in Social Networks,” (w. Kovarik, Ozaita @anxosanchez.bsky.social) is now showcased on Kudos.

We show that people seriously misjudge their own popularity and centrality — and it matters.

This paper shows is that people have a very poor perception of their own popularity, and an even worse of their position in the network. And if people are not aware of where they stand, how can they anticipate the impact of their actions on the network? Think about contagion, gossip, and so on.

Y Dª. Carmen Calvo Poyato?

If most people (54%) are between 2 and 5, then this isn’t well calibrated. You should have a 2–3 category and a 4–5 category.

Repetir curso podría no ser una buena idea: las consecuencias negativas para los alumnos, según un estudio Con el comienzo de curso a la vuelta de la esquina, toda la comunidad educativa se hace una pregunta recurrente: ¿Sirve de algo repetir curso? Exist

Ayer me entrevistaron para hablar del trabajo "La repetición perjudica la inclusión social en la escuela" en el usamos gemelos estadísticos - propensity score matching - para estudiar los problemas de los alumnos que repiten.

School counselors' recommendation letters for minority students are shorter and emphasize character over achievement.

Fresh out of the oven! 🍞 With AM Espin, MP Espinosa & MJ Vazquez), we examine whether mentoring programs for vulnerable youth foster in-group bias. The results are surprising: the young person’s background and the program’s duration have a huge impact.

This is why many researchers only use OLS.

This week, I gave a talk at the 3rd Soleto Summer School — an experience I’ll remember for a long time. It took place in a beautiful square in the heart of Soleto, with a wonderfully diverse audience.

Thanks Giuseppe Attanasi and the entire CIMEO Sapienza U Roma

Lol who did this

Acabo de recibir la fantástica noticia de que he sido galardonado con el Premio de Divulgación Científica de la @uji.es. Si es bueno que te den un premio así, todavía es mejor que te lo reconozcan en tu propia casa (sigue)

Congratulations to Aleksei Samkov for successfully defending his Ph.D. thesis at CEMFI!. Thanks to Pedro Mira, Silvia Sarpietro and Kirill Evdokimov for serving in the Thesis Defense Committe and to Aleksei’s advisor Dmitry Arkhangelsky

Evidence based policy, right?

Like everything in life, this has its ups and downs.

Pues muchas felicidades!

After two very intense days, BiNoMa has come to an end. Thank you Lorenzo, Arnold, Norma, and the University of Granada. @universidadgranada.bsky.social

El año que viene la @uc3m.es estrena grado en Matemática Aplicada. Para aprender matemáticas no lo recomiendo. Para aprender matemáticas y aplicarlas en distintos campos y resolver problemas reales, vente. Yo creo que además aprenderás matemáticas. Bien aprendidas

Abstract: The open science movement has gained significant momentum over the past decade, with pre-registration and the use of pre-analysis plans being central to ongoing debates. Combining observational evidence on trends in adoption with survey data from 519 re-searchers, this study examines the adoption of pre-registration (potentially but not necessarily including pre-analysis plans) in experimental economics. Pooling statistics from 19 leading journals published between 2017 and 2023, we observe that the number of papers containing a pre-registration grew from seven per year to 190 per year. Our findings indicate that pre-registration has now become mainstream in experimental economics, with two-thirds of respondents expressing favorable views and 86% having pre-registered at least one study. However, opinions are divided on the scope and comprehensiveness of pre-registration, highlighting the need for clearer guidelines. Researchers assign a credibility premium to pre-registered tests, although the exact channels remain to be understood. Our results suggest growing support for open science practices among experimental economists, with demand for professional associations to guide researchers and reviewers on best practices for pre-registration and other open science initiatives.

Wow.

Look at how rapidly preregistration has become the norm in experimental economics.

In our new series, Office Hours, we talk to faculty about their research, classes, and academic pursuits. Meet Benjamin Ho, Professor of Economics, who specializes in behavioral economics.

Awesome!

Desconozco el tema en profundidad pero da la impresión de que todos son ventajas (vía impuestos) si los costes ya se han asumido (educación, sanidad, etc.).

Seguramente me pierdo algo, pero cuál es la pega de legalizarlos?

Es un gráfico muy bonito pero honestamente, no tengo claro si a la gente “corriente” le importa mucho este dato… creo que están en otros problemas.
