Careful reader John Bullock writes:
I think that there may be a small error on page 185 of Mostly Harmless Econometrics. It lies with the y-axes for the panels of Figure 4.5.1. Those panels are from pages 32-33 of Acemoglu and Angrist 2001 (http://www.nber.org/chapters/c11054.pdf), but in the Acemoglu-Angrist article, the y-axes range from -.03 to .07. In MHE — at least, in my printing — they range from -.2 to .6 and from -.1 to .4. I think that the axes are correct in the article, incorrect in MHE. But please don’t hesitate to let me know if I’m wrong about that.
We’re not hesitating John – you’re right! The axes in MHE Fig 4.5.1 should be divided by 10. Yikes!
