🤝 Persönliche #Netzwerke spielen bei der #Jobsuche eine wichtige Rolle. Eine IAB-Studie zeigt jedoch: Männer nutzen soziale Kontakte häufiger und gezielter als Frauen. Frauen werden deutlich seltener potenziellen Arbeitgebern vorgestellt oder empfohlen. #IABForum 👉🏽 iab-forum.de/maenner-nutz...

Zwei Männer gehen nebeneinander und unterhalten sich. Der Mann links trägt einen schwarzen Anzug, der Mann rechts trägt helle Jeans, ein weißes T-Shirt und ein graues Jackett. Im Textfeld steht: Männer nutzen persönliche Netzwerke zur Jobsuche etwas häufiger und gezielter als Frauen.

Der Anteil von Frauen und Männern, die soziale Kontakte für die Jobsuche nutzen, unterscheidet sich kaum, aber Männer greifen häufiger als Frauen darauf zurück.
Zwar nutzen Frauen diese Netzwerke ähnlich oft wie Männer, um Informationen über Arbeitgeber oder freie Stellen zu erhalten.
Frauen werden aber deutlich seltener als Männer potenziellen Arbeitgebern vorgestellt oder empfohlen.

Overall, we see no causal effects of zodiac signs on wages. 16/n

Matthias Collischon 🇺🇦🇪🇺 @mcollischon.bsky.social · 30/04/2026

Regarding the energy, we find no significant differences between male and female zodiac signs (early refers to the beginning of the male signs compared to the end of the female signs). 13/n

100

Matthias Collischon 🇺🇦🇪🇺 @mcollischon.bsky.social · 30/04/2026

However, these effects can be driven by e.g. seasonal effects. To estimate the causal effect of zodiac signs, we use a RDD design, comparing people burn just around the cutoffs of the sign changes. 12/n

Matthias Collischon 🇺🇦🇪🇺 @mcollischon.bsky.social · 30/04/2026

Our main outcome of interest is daily pay. Interestingly, we descriptively observe significant differences in average daily pay by zodiac sign. 11/n

Empirically, we use the SIAB data from the Institute for Employment Research (@iabnews.bsky.social) that contains information on the labor market histories of around 1 million individuals, covering more than 11 million observations. 10/n

Lastly, we hypothesize that Being born to fire, earth, and air signs leads to higher wages than being born to water zodiac signs (H3) 9/n

Matthias Collischon 🇺🇦🇪🇺 @mcollischon.bsky.social · 30/04/2026

Matthias Collischon 🇺🇦🇪🇺 @mcollischon.bsky.social · 30/04/2026

In theory, being born with a sign with masculine energy is said to be associated with personality traits that correlate with higher wages (H1) 7/n

Matthias Collischon 🇺🇦🇪🇺 @mcollischon.bsky.social · 30/04/2026

Western zodiac signs encompass energies, modalities, and elements that can theoretically be linked to personality traits that, in turn should affect wages (see the paper for details). 6/n

100

Matthias Collischon 🇺🇦🇪🇺 @mcollischon.bsky.social · 30/04/2026

In the case of western zodiac signs, we argue that the effects play out via personality traits. If individuals believe zodiac sign is associated with a specific personality trait, they could be more likely to behave accordingly, which could affect labor market outcomes. 5/n

Matthias Collischon 🇺🇦🇪🇺 @mcollischon.bsky.social · 30/04/2026

The channel here likely is a self-fulfilling prophecy: teachers and parents invest more in “dragons” due to their believe in Astrology, leading these children to attain higher educational degrees and, in turn, higher wages. 4/n

100

Matthias Collischon 🇺🇦🇪🇺 @mcollischon.bsky.social · 30/04/2026

Of course, zodiac signs themselves should not affect labor market outcomes directly. But research on Chinese zodiac signs shows that dragons – even in Germany – earn higher wages (see the paper by Florian Zimmermann). Why is that the case? 3/n

Matthias Collischon 🇺🇦🇪🇺 @mcollischon.bsky.social · 30/04/2026

Matthias Collischon 🇺🇦🇪🇺 @mcollischon.bsky.social · 17/04/2026

We hypothesize that large real wage increases, as occurred in Germany between 2019 to 2023 for the group of low-wage workers due to a substantial minimum wage hike of ~20%, should increase institutional trust. We investigate this hypothesis using data from PASS (@iabnews.bsky.social) 2/n

We also investigate measures of job quality, i.e., job satisfaction, psychological health, and social integration, as outcomes. Again, we observe no significant effects (the picture shows cross-sectional regression results; FE mirrors them). 6/n

Matthias Collischon 🇺🇦🇪🇺 @mcollischon.bsky.social · 16/02/2026

This finding is mirrored in the FE regression results, where we find only one significant negative correlation between starting WFH and activity (with large confidence bands). 5/n

Matthias Collischon 🇺🇦🇪🇺 @mcollischon.bsky.social · 16/02/2026

We use cross-sectional and fixed effects regressions to estimate whether starting/stopping or always WFH is associated with the latent functions of employment. The cross-sectional regressions show no significant correlation between WFH and latent factors. 4/n

Matthias Collischon 🇺🇦🇪🇺 @mcollischon.bsky.social · 11/02/2026

Political science also has qualitative work, this should be no excuse for the lack of reproducability criteria in empirical papers. It also seems correct to me that the credibility revolution has not fully reached sociology, even for quantitative empirical papers.
