keep those corrections coming!

our corrected printing notwithstanding, we certainly didn’t catch them all . . .

here’s a few more from Aron “eagle-eye” Tobias at Yale:

The book is really great but I need not tell you that since you
probably know that already. What I would like to share with you is
some possible typos (all are really minor, though):

 * pp. 123--125. There are multiple minor inconsistencies between
figures reported in table 4.1.1 and the text. On p. 123, it is claimed
that "[i]n both cases, the estimated return to schooling is around
.075[,]" whereas the figures reported in columns 1 and 2 in table
4.1.1 are .071 and .067, respectively. Similarly, the assertion that
"[t]hese estimates range from .10 to .11[,]" appears on the same page
but columns 3 and 4 in the table indicate .102 and .130, respectively.
In addition, on p. 125, "...the standard error declines from .019 to
.016 as we move from column 6 to column 7" but the table indicates
that it declines from .020 to .016, presumably because of the figures
in the table and the text being rounded differently.

* p. 130 "The Wald estimate of the effect of military service on 1981
earnings, reported in column 4[;]" in fact, they are reported in
column 5.


* p. 131. By "...defined using the 1952 lottery cutoff 95..." you
probably mean the 1972 lottery.

* p. 132. "...a multiple third birth increases this proportion to 1"
should be "...a multiple second birth [i.e. a second birth in which
the second and third babies are twin-born] increases this proportion
to 1."

* p. 351. The Hausman (2001) reference has the title of the journal
wrong (Journal of Econometric Perspectives should be The Journal of
Economic Perspectives).

I apologize in advance if any of my claims turns out to be erroneous.

I remain your faithful reader,
Aron Tobias

thanks Aron
All I can say is, how come Steve didn't catch these last year?!
