The Dutch papers are reporting that Peter Nijkamp, one of the leading economists in The Netherlands, has been embroiled in what looks like a self-plagiarism scandal following the cancellation of a thesis defense by one of his graduate students because of plagiarism.
We say “what looks like” because it’s tough to figure out what’s alleged here, given our reliance on translations. Best we can tell, the allegations against his graduate student are for plagiarism, while those against Nijkamp are for duplication, a.k.a. self-plagiarism.
The other day, we wrote about two retractions in the Journal of the American College of Cardiology, and another in the American Heart Journal, stemming from database errors.
Seems to be catching.
The Economist (among other outlets) this week is reporting about a similar
nother database glitch — not, we’ll admit, a retraction — involving a landmark 2010 paper by a pair of highly influential economists. The controversial article, “Growth in a Time of Debt,” by Harvard scholars Carmen Reinhart and Kenneth Rogoff, argued that countries that took on debt in excess of 90% of their gross domestic product suffered sharp drops in economic growth. That evidence became grist for the austerity mill, including Paul Ryan.
Turns out, that conclusion was based to some extent on an Excel error. Read the rest of this entry »
Markets undergo flash crashes — when stocks or bonds rapidly nosedive in value and then just as rapidly recover — every day. On May 6, 2010, for example, the entire equity market flamed out and then nearly recovered its value all in the matter of hours.
“[A]ll of Section 3 is wrong until proven otherwise”: Correction of paper on Democrats’ economic policy
Andrew Gelman, a statistician at Columbia University and a friend of the blog, has corrected a 2008 paper in the blunt way you’d expect him to.
Here’s the notice in the Annals of Applied Statistics:
In the paper, “Should the Democrats move to the left on economic policy?” AOAS 2 (2), 536-549 (2008), by Andrew Gelman and Cexun Jeffrey Cai, because of a data coding error on one of the variables, all our analysis of social issues is incorrect. Thus, arguably, all of Section 3 is wrong until proven otherwise. We thank Yang Yang Hu for discovering this error and demonstrating its importance.
A frequent co-author of Ulrich Lichtenthaler — the management professor who has retracted at least eight papers — has now withdrawn one of his own from Research Policy.
The original paper, “How to create commercial value from patents: The role of patent management,” by Holger Ernst and colleagues, went online on May 21, 2012. Here’s the notice: Read the rest of this entry »
Late last year, we covered a paper wondering why there were so few retractions in business and economics journals. That post was on our minds as we read a fantastic piece of reporting by reporters at the Scarlet & Black, the Grinnell College student paper.
The story concerns Brian Swart, a Grinnell economics professor who “abruptly resigned in the middle of last semester,” reporters Peter Sullivan and Hayes Gardner note. As is unfortunately often the case, the university wouldn’t say why Swart was leaving. But Sullivan and Gardner didn’t leave it there. They talked to “professors from other institutions involved in the situation” and got the food of investigative reporters everywhere: Documents. Those interviews and documents showed that: Read the rest of this entry »
Two papers by researchers from China and Taiwan have been retracted from two journals, one based in the US, one in Croatia, after identical studies appeared in the June 2011 issues of both publications.
Eastern European Economics retracted their version first, and that journal’s editor discussed the case with the editors of Proceedings of Rijeka Faculty of Economics: Journal of Economics and Business, where the same paper was also published.
In “Retraction, Dishonesty and Plagiarism: Analysis of a Crucial Issue for Academic Publishing, and the Inadequate Responses from Leading Journals in Economics and Management Disciplines,” which just went online in the Journal of Applied Economics and Business Research (JAEBR), Solmaz Filiz Karabag and Christian Berggren identified 31 retractions in business journals dating back to 2005, and just six in economics journals, dating back to 2009.
The numbers in business journals are even lower when you consider that Read the rest of this entry »
