Difference-in-Differences Designs: A Practitioner’s Guide (Forthcoming Article) - Difference-in-differences (DiD) is arguably the most popular quasi-experimental research design. Its canonical form, with two groups and two periods, is well-understood. Howeve...

The tragic landslide in Blatten gives me the excuse to tell you the story of how we found out Ice Ages existed. It's a cool story and the most important bit is rather similar to what's happening now.

@agueda-sa.bsky.social (@economicsunito.bsky.social, Coll. Carlo Alberto) ends the panel with “Work Harder or Work Smarter? The Effects of Academic Distinctions on Early Careers”. Her research finds no advantages in earnings/job search, but sectoral sorting effects and gender disparities can persist

Does drinking this much coffee lower the risk of omitted variable bias?

🎓 We find:
Affiliation impacts acceptance chances (controlling for paper quality), benefiting authors from top institutions
Driven largely by in-group favoritism among reviewers from similar institutions
Affiliation bias affects women and first-gen applicants’ representation

We compare evaluations under both grading schemes, keeping the quality of the paper constant, and allowing us to isolate the effect of institutional affiliation on the evaluation of the papers

We create 2 versions of each submission: one with visible affiliation and a non-visible affiliation (blind) version. We use applicants to the event as reviewers, and randomly pair them to read the same set of papers, one reviewer in the visible version, the other in the blind one.

We designed a matched-pairs field experiment, and ran it during the reviewing phase of an early-career workshop at a French university. We focus on conferences because they are crucial events for the development of ideas and networks, particularly important for junior researchers
