I'm trying to follow Juhn-Murphy-Pierce (1993)
wage decomposition and have some questions.
If the data I'm using is a survey data (labor force
and it has a weight (sampling weight)
attached to each
observation, then when I do jmpierce do I need to
about the weight?
I have read some literature but I don't seem to see
mentioning anything about this weight.
(Maybe I'm missing something -- can you please point
the literature that discuss it?)
Basically, if I want to calcuate p90-p10 of log wage of
in 2000 (and 1995) -- and to describe it as a measure of
of the country then I need to use weight,
So when I decompose how p90-p10 change from 1995 to
I should also consider weight?
But, (from the help file of jmpierce)
y1_i1 = x_i1b + F[-1](p_i1|x_i1) --- for year
y1_i2 = x_i2b + F[-1](p_i2|x_i2) --- for year 1995
are "hypothetical" distributions, thus if I am to calculate
(to be used in future steps of the decomposition) from these
want to use weight then the weight
attached to the observation i
wouldn't be correct anyway?
So should I just ignore the weight in the
But what about when I want to discuss the summary
(as mentioned before) like p90-p10 inequality measure in
then I believe the weight is important?
Could anyone please help me clarify this?
Thank you very much.
