Our comment on “Raising Health Awareness in Rural Communities” is finally published in REStat (MIT Press). But the retraction we had been told was coming never happened. Can lawyers derail a retraction? This case raises that uncomfortable question. 🧵

Incentives to reproduce and replicate articles are so bad. Even when your comment leads to the retraction of a PLOS One article, the reward is a (10 days late) email with a thank you at the bottom. Retraction notice: journals.plos.org/plosone/arti.... But we are not complaining about PLOS One 🧵

#GDRI_rep Update 10 The orphan article has finally been retracted! Took more than a year, but at last. Read about our investigation (bsky.app/profile/i4re...) and updates ( #GDRI_rep). A good summary: a-ortmann.medium.com/the-asad-isl... and a-ortmann.medium.com/tallying-the...

#GDRI_rep Update 9: We have been waiting a couple of months to make two announcements. A few journals were in the process of retracting GDRI article. The editors informed the authors and then lawyers got involved. Who knows how long it will take.

Female PhD students (in economics) benefit tremendously from having female faculty around. When female professors go on leave, it decreases third-year female PhD students’ likelihood of publishing & securing academic positions. papers.ssrn.com/sol3/papers....

Update: We submitted the comment to the Journal of Population Economics, and today we got a desk reject with this motivation. However, we do not know their conclusion about the main results and why the paper was not retracted. Clearly, they do not hold. 1/4

👏 Good news for researchers working with Swedish register data and who want their research to be reproducible 👉 If you include in your ethics application/research plan that replication may be part of the project, then external replicators (e.g. data editors) can be given access to the data!

New working paper! How Business Income Measures Affect Income Inequality and the Tax Burden, with Aaberge, Francesconi and Vestad. Using Norwegian administrative data, we show that income inequality is much higher than commonly measured. Measurement matters! www.iza.org/publications...

$This paper presents estimates of income concentration and inequality for Norway using a new comprehensive measure of income, which identifies business income as it is earned by companies rather than when it is paid out as dividends to owners. We assemble several sources of high quality register data that allow us to account for multiple layers of business ownership across all companies between 2001 and 2018. Compared to official statistics, the new measure implies that the share of income attributable to the top 1\% of the distribution more than doubles and the Gini coefficient estimates increase by about 40\%. Our new measure identifies substantial tax regressivity for individuals in the top percentile, a feature that cannot be detected by standard income measures. For instance, while the share of gross income paid in taxes by individuals at the 99th percentile is about 36\% in 2016, the corresponding share paid by individuals in the top 1\% is 19\%.$
