Thereby suggesting that segregating children for language acquisition may slow academic integration.

Using German administrative data, the authors find that elementary-school-aged refugee children placed in separate preparatory language classes perform worse on standardised tests in grade five compared to those directly integrated into regular classrooms.

This study examines the impact of this change on p-hacking and publication bias. The author employs a diff-in-diff design, as well as the battery of tests proposed by Elliott et al. (2022b). The author finds no statistically significant effect of this policy.

In mid-2016, all journals of the American Economic Association (AEA) stopped including significance stars in their regression tables. This policy aimed to reduce the emphasis on statistical significance and shift the focus to the broader economic importance of research findings.

Using French administrative panel data, the authors show that despite lower pay, the public sector attracts higher-skilled workers. However, this edge fades over time and vanishes at the top, calling for policies to restore the attractiveness of public management careers.

The authors assemble a novel measure of ASgM exposure, showing that this exposure increases with the international gold price in places where the geological layer underneath the surface is suitable for bearing gold. [Figure 1 shows the extend of gold-suitable geological layers.]

ASgM consists of widespread, labor-intensive, typically informal if not illegal, gold mining operations. The nature of the activity makes it excessively difficult to study its impacts.

The paper shows that exposure to artisanal and small-scale gold mining (ASgM) causes significant deforestation across Africa.

Do social norms drive the “polarization of reality” in American politics? We find Dems and Reps identify divergent norms governing factual statements, punish co-partisans who make politically uncongenial statements, and give less accurate answers when party norms are salient.

At the onset of COVID-19, invention novelty in the densest US cities fell sharply, largely due to lost face-to-face interactions. This shows that urban density’s role in idea exchange and recombination is critical, and unlikely to be permanently replaced by online communication.

Firms can exploit immigration by imposing larger mark-downs on native wages – if they have greater monopsony power over migrants than natives - but cannot perfectly wage-discriminate between them. The authors substantiate their claim empirically using US skill cell variation.
