It just keeps getting worse for Bruno Frey.
I can't help but wonder though how many folks would survive similar examination. As we strive towards the "least publishable unit" as the optimum rather than articles that exhaust a particular line of investigation, there's always going to be substantial overlap in material across journal articles. The literature review and contextualization will be similar. Maybe the next iteration of the paper has a specification or two that weren't included in the first published version. But the main thrust of the results are similar.
Eventually, somebody will run EconLit, JSTOR and SSRN through TurnItIn. And the results won't be good.
