  1. Note: The table compares results from first difference models (i.e. the difference between the logarithm of the post-birth and pre-birth wage) in the IABS, after imposing my preferred restrictions (“Approx.”) with those in the Pension Register (“true”). Here, I distinguish two samples. In the first column, spells that start on the first of a month are included in the sample. In the second column, they are excluded. Robust standard errors in parentheses.
