Wages and institutional trust between 2019 and 2023 - Matthias Collischon, Alexander Patzina, 2026 While research on income inequality and institutional trust mainly focuses on how actual changes in inequality and individuals’ perceptions affect trust, we kno...

Overall, our findings imply that even policies that substantially reduce income inequality may only have limited effects on strengthening social cohesion. The paper is available (OA) here: journals.sagepub.com/doi/10.1177/... 5/End of Thread

We find that, even though real wages increased dramatically for the group below the minimum wage threshold, institutional trust is not significantly correlated with this wage increase 3/n

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

Is working from home changing the meaning of work? Especially since the COVID-19 pandemic, working from home (WFH) has become a common practice in the workplace. This raises the question of whether WFH changes the non-monetary benefits of work, such a...

Overall, our results show that WFH is neither beneficial nor harmful for employees’ well-being, in contrast to some anecdotal evidence. The paper is available (OA) here: journals.plos.org/plosone/arti... 7/End of Thread

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

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

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

We use data from the Panel Study Labour Market and Social Security (PASS) to investigate whether working from home affects latent functions of work: providing time structure, social contacts, collective purpose, status, and activity to the same degree as working on site. 3/n

Working from home has become common in the labor market: In Germany, in 2023, around 24% of employees reported working from home some days (www.destatis.de/EN/Themes/La...). Does working from home also fulfil latent functions of work, like social contact? 2/n

Women use Social Networks for Job Search more often than Men, but Men use them more intensely Research has long highlighted the role of social capital for labor market outcomes, but gendered processes received surprisingly little attention. Emp…

Overall, our study highlights the importance of looking at gendered differences in social networks in detail to understand the role of social networks in labor market outcomes. 5/5

Further analyses show that the effect is mostly driven by differences among highly educated individuals, where professional networks could be important for career prospects. 4/5

However, analyses of the job search channels show that men, conditional on job search via social networks, receive more in-depth support, for example they are significantly more often introduced to employers compared to women. 3/5

Interestingly, and maybe contrary to expectations, women report using social networks for job search more often than men. 2/5

Warum Minijobs beliebt und umstritten sind Minijobs sind beliebt, bringen aber of keine Sicherheit. Für viele Beschäftigte ist der Minijob eine Sackgasse und ein Weg in die Armutsfalle.

Guter und ausführlicher Beitrag von Deutschlandfunk zu Minijobs, zu dem ich auch ein paar Worte beisteuern durfte:

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.

Even if you do not care about the political beliefs of researchers, columns II and III on transparency and causal identification in sociology should worry you (although, of course, there is valuable descriptive research):
