I wonder why they aren't in the sample... because many were still colonies in 1900? No data? If so then this might be selection bias. Also, by this metric several of the world's most successful economies of the past 100 years (e.g. U.S., Canada, Germany, U.K.) have actually underperformed slightly: they're below the regression line. (actually the pattern looks clearly nonlinear to me, but whatever.)<br /><br />Gabby -<br /><br />Mea culpa. But I think the overall point still stands. And actually, reverse causation could have a role if Argentina was unable to maintain or expand education over the 100 year period to keep pace with the other countries in the sample (something that Glaeser does not examine, and that I imagine is not actually the case, but it could be).Kindred Winecoffhttps://www.blogger.com/profile/14330671232391851377noreply@blogger.comtag:blogger.com,1999:blog-1331441403058020963.post-70935069638122609752009-10-09T07:05:32.035-04:002009-10-09T07:05:32.035-04:00That's a lot of weight to attach to a five-poi...That's a lot of weight to attach to a five-point difference (Arg vs. Japan) in school enrollment 100 years ago. I suspect the word you are searching for to characterize this finding is "spurious."<br /><br />I notice that East Asian societies are not included in the sample. I hypothesize that their inclusion would weaken the relationship substantially.Thomas Oatleyhttps://www.blogger.com/profile/14092437150746625670noreply@blogger.comtag:blogger.com,1999:blog-1331441403058020963.post-57799116221259467282009-10-09T01:56:52.721-04:002009-10-09T01:56:52.721-04:00in this cause, you cannot argue reverse causation,...in this cause, you cannot argue reverse causation, coz the graph is education 100 years ago, to income per capita today.GabbyDnoreply@blogger.com
