That's possibly vaguer than it could be but it doesn't seem meaningless. I'd take FAR issue more with the fact that the authors appear to have mixed up correlation and causation. e.g. the fact that, say, international conflict causes a bad economy and populism (the "war is bad" theory) appears to have flown completely under the radars of Manuel Funke, Moritz Schularick and Christoph Trebesch. Also the fact that GDP is well known to be a shitty measure of well being for the average person. Nonetheless, it is a pretty good measure of how things are going for that particular country's oligarchy (the targets of those populists). There is a strong causal relationship between using GDP as a measure and getting published in the AEA, though.
