The effects are most prevalent in skilled trades. However, we also report that drop out rate is very high in this sector. So one explanation is for sure liked to statsitical discrimination. Note the high response rate of the municipalities that seek apprentices every year.

we inform a decision model that makes this pattern theoretically understandable and, for the first time, clearly distinguishes between opportunism and persuasion effort in political interactions with voters. (4/5)

🔍 Three key findings: 1. Partisanship: Candidates are more likely to respond when the voter's opinion aligns with their own party line. 2. Opportunism: The expressed stance often adapts to the voter's opinion – sometimes contrary to the expected party line. (2/5)

First-time voters hold polarized views on migrant issues. How do politicians react to this phenomenon? To find out, we contacted 1,554 candidates before the 2021 German federal election as (non-)migrant first-time voters and vary their stance on dual citizenship. Openaccess!(1/5)

The state of research on AI and education from controlled studies: Growing evidence that, when used as a tutor with instructor guidance, AI seems to have quite significant positive effects. When used alone to get help with homework, it can act as shortcut that hurts learning.

Still early days.
