6 hours 30 mins they could do from this December, with one change in Badajoz or Elvas - but they're likely not going to do though So 🤷‍♂️ Whenever I hear about these long term plans for ES-PT rail, I wonder why they're not doing the basics with what they have right now? #CrossBorderRail

Brauchen wir eigentlich Steuererklärungen? Wer profitiert wenn wir die automatisieren? Und warum würde das die Verteilungswirkung der Einkommensteuer erhöhen? Darüber habe ich mit Marilena Piesker @zeit.de gesprochen 🗞️ www.zeit.de/geld/2025-07...

Abschaffung der Steuererklärung: Nie wieder Steuererklärung!

Die Steuererklärung abschaffen? Klingt verrückt, aber eine vorausgefüllte Erklärung könnte viel Zeit und Geld sparen – und das Steuersystem gerechter machen.

Hey researchers, bloggers, everyone interested in fertility data! We recently added lots of new data at Our World in Data on fertility rates, ages at childbirth, twin birth rates, birth seasonality, and more. Here's a thread of what you can find on the site! 🧵

Hello #EconSky! 📢Excited to share my #JMP 📢 It provides a missing piece to understand how people react to income taxation. Tldr: By changing tax pre-payments governments can - with almost no costs - increase perceived work incentives of secondary earners and reduce the gender gap. Thread below👇🧵

To collect income taxes, almost all countries require employers to withhold monthly tax prepayments which are then fully credited against the final income tax liabilities of their employees. Despite being a fundamental component of income taxation systems worldwide, the impact of these withholding taxes on labor supply is poorly understood. We investigate their importance in the context of married couples in Germany where the withholding tax liability can be redistributed between spouses. We exploit a reform that reduced the withholding tax for some married women more than for others, while inducing no differences in income taxes. Using administrative data for the full population of German taxpayers, we estimate an elasticity of labor income with respect to the withholding tax eight years after the reform of 0.14. Additional evidence from a self-conducted survey suggests imperfect understanding of the tax system and limited pooling of resources within the household as the main mechanisms. As the majority of couples shift parts of the withholding tax liability from the husband to the wife, our results suggest that the increased withholding tax liability of married women contributes to their low labor supply. This highlights the need for governments to be aware of the distortion of labor supply incentives when the design of withholding taxes does not match actual income tax incentives.

Ever wondered how discrimination affects job networks? In our two-stage experiment on LinkedIn, we provide insights into the question, causally studying the effect of discrimination on Black individuals' job networks in the U.S.

JMP alert 🎉 What drives maternal labor supply - a key factor for labor market inequalities? Gender role attitudes! We use reduced form and structural methods to show that they are of first-order importance, both directly and through the mediation of policies (w/ Tim Mensinger) 🧵👇
