@EuropeanPan In Spain, we say: where there’s room (to feed or host) X, there’s room for X+1. This applies to any natural number ☺️.

Dutch, actually. It's a North European thing, you wouldn't understand. Considering it cultural anthropologically, I feel it is a rare pocket of in-group preference particular to our cultures. On a societal level we are very hospitable (often to our own detriment, as is well known). However, eating together is seen as an intimate and cherished family moment. You can't just barge in and expect to be fed. But if you are part of the dinner plans, we are the most welcoming and generous dinner hosts. In fact, from our perspective, it feels kind of socially constraining to be always ready to give any random visitor the feast of their lifetimes, as I've seen in many Mediterannean cultures.

Yay... after 7 or so years, finally accepter ... at JPE!

In a new working paper, I show that large language models recover ethnicity from names; outperform existing methods; perform well comparatively, using original voter rolls in countries like Armenia and Nepal; and generalize to any classification group.dropbox.com/scl/fi/mzg35lh…

Esto es hermoso, emocionante. En pleno centro de Teherán, la capital de Irán, las mujeres se están quitando los velos y los prenden fuego. Todo un símbolo de liberación. La mayor revolución femenina del siglo XXI está ocurriendo frente a nuestros ojos ahora mismo.

These authors wanted to know whether mothers face discrimination in hiring, even when they are equally qualified as other applicants. So they ran two experiments. First, a lab experiment: participants evaluated pairs of identical job applicants who differed only in parental status. Then, a real-world audit study: they sent 1,200+ job applications to real employers for entry- and mid-level jobs. They randomized whether applicants were: – Mothers (based on serving on the PTA) – Childless women (they were listed as volunteering in a non-parent specific role) – Fathers (based on serving on the PTA) – Childless men (they were listed as volunteering in a non-parent specific role) All applicants had identical qualifications. Then they tracked evaluations, salary recommendations, and employer callbacks. They found that: Mothers were rated as less competent and less committed than equally qualified childless women. Mothers were held to stricter standards, offered lower salaries, and were far less likely to be hired or promoted. In the field experiment, real employers called back childless women at more than twice the rate of mothers. Fathers, by contrast, faced no penalty and sometimes received a bonus. Bottom line: The “motherhood penalty” is real, causal, and driven by discrimination, not differences in ability. As the authors put it: “Giving evidence of being a mother leads to discrimination against mothers in hiring and pay.”

@jfjimenoserrano @miotroblog sobre todo al que lo vende, sí.

@beagosma @miotroblog En realidad, aparcamiento urbano es gratis (en Madrid y otros sitios), el seguro anual es más barato y la amortización es cuenta del concesionario si eliges opción de compra flexible. Te aseguro que he hecho todas esas cuentas y el coche eléctrico, como se dice ahora, renta.

#MiCocheEléctrico Resumen del año: 40.512 kms. Coste de recargas (incluidas las domésticas): 918 euros. Coste por km.: 2,27 euros/100 kms. Mantenimiento: 613 euros (por cambio de neumáticos) Ahorro estimado frente a vehículo de combustión: 3.000 euros.

@jfjimenoserrano @miotroblog amortización es en efecto el gasto fundamental (precio, valor residual y vida útil seguramente son distintos), así como otros gastos potencialmente diferentes, como, e.g., seguro anual o coste de plaza de aparcamiento (necesaria para coche eléctrico).

@miotroblog @beagosma No hay tanta diferencia ni en precio ni en amortización.

La endogamia produce académicos que no son conscientes de la mediocridad de su investigación ni de las revistas, grupos y congresos en los que se mueven —y de los que nunca han salido. Y poco ayuda una universidad que valora igual revistas de excelencia que revistas irrelevantes.

Experimental evidence that students are significantly more likely to contest grades when it is delivered by an evaluator with a female-sounding name. "These findings suggest that women in evaluative positions face disproportionate resistance when delivering negative assessments and have implications for their authority, credibility, and career advancement in both educational and workplace settings."

When a firm is targeted by an activist short seller, the consequences go beyond stock prices. We show that banks tend to increase interest rates on new loans after a short report is released—above changes in credit risks. forbes.com/sites/hecparis…
