  In their IZA Discussion Paper 10247, Johansson and Lee claim that the main
result (Proposition 3) in Abbring and Van den Berg (2003b) does not hold. We
show that their claim is incorrect. At a certain point within their line of
reasoning, they make a rather basic error while transforming one random
variable into another random variable, and this leads them to draw incorrect
conclusions. As a result, their paper can be discarded.
