The empirical analysis carried out in this paper relies on data from
the German Socio-Economic Panel Study (SOEP).  The SOEP is a
representative longitudinal household panel study designed by the SOEP
GROUP at the German Institute for Economic Research (DIW Berlin).

The SOEP is a confidential dataset that is governed by strict German
data privacy protection laws.  Consequently, researchers who are
interested in using this dataset are required to formally apply for
data access and sign a confidentiality agreement. They also have to
pay a small fee before they receive the data DVD and a passcode.
Researchers outside the European Union can only obtain the
international version of the SOEP, which contains only 95% of the
original German version. 

Inquiries about data access should be adressed to <soepmail@diw.de>.
Further details can be found on the webpage above.

The SOEP DVD contains various "generated" variables, mostly on income
and education.  This is part of the SOEP service. The SOEP team also
updates these generated variables annually and retrospectively in
order to keep them bug-free. This means that it will be almost
impossible to exactly replicate the findings from this study with the
most recent version of the SOEP (SOEPv27). The paper and all results
rely on SOEPv23. 

The working datasets for this paper are stored in the SOEP Archive.
The SOEP Archive is a new service of the SOEP Group to facilitate
re-analysis. Researchers inteersted in replicating the results of this
paper are required to contact <soepmail@diw.de> and apply for data
access to the SOEP Archive. However, the standard SOEP access 
application procedure applies. In order to get access, researchers
have to sign a data distribution contract. More details can be found
here:

The SOEP Data Archive for this article contains the following datasets:

JAE_Mainanalysis_clean.dta (survey waves '98 to '00; full-time
  employed aged 25 to 55)

JAE_LaborCostIncrease.dta (survey waves '98 to '00; all employed
  people)

The zip file "zk-files.zip" contains several identically named Stata
do-files and log-files.  After having customized the paths of the
do-files, running them should produce the according log-files. The
file also contains variables-zk.txt, which describes all the variables
used in the analysis. These are all ASCII files in DOS format, so
Unix/Linux users should use "unzip -a".
