EconLog reader Matthew Baker has detected an error in my spreadsheets on the social return to education.  Fortunately, the mistake – a miscalculation of crime risk for the elderly – is so small that none of the main results change by even a tenth of a decimal place. 

Still, all the files have been updated, and I’m immensely grateful to Mr. Baker for being so meticulous.  I’ll certainly be thanking him in the book credits when the project’s done.
