Original Data and Source Codes
These files are now somewhat outdated and need to be updated to use the most current data.
Job Finding and Employment Exit Probabilities
This file is self-contained. The original data and source codes are compressed in .zip files. Uncompress the files and look at the readme for more instructions. The source code is written in Mathematica. You will need this commercial program to replicate the results; however, the source code should be readable using the free Mathematica viewer, Mathreader.
Gross Worker Flows
To use these files, you must download the basic monthly CPS files from January 1976 to January 2005. The raw data files are available online at https://www.nber.org/research/data/current-population-survey-cps-basic-monthly-data. The compressed files require about 3GB of disk space. The uncompressed files require about 30GB of space.
Uncompress the raw files, place them in the folder c:\cps, and name them cpsbYYYYMM.raw. Finally, place the uncompressed files you download here in the same directory. Using Stata (version 7.0 or later), type cd "c:\cps", hit enter, and type do match. This will output six text files containing the gross flows data.
Stata will also create many small monthly files. You can delete the files named cpsYYYYMM.dta. You may wish to keep the files named mergYYYYMM.dta. By modifying the file match_flows.do, you can quickly construct measures of gross flows conditional on age, sex, race, and other observable characteristics that are included in the merged files. Please look at the source code and the CPS codebooks for more information on the characteristics that are included in these files.
To correct for time-aggregation, run the Mathematica program three-state.nb. This will output six .dat files containing the instantaneous transition probabilities between employment, unemployment, and inactivity. Those are the six transition rates listed above under Main Results. It will also output .dat files containing the contribution of each of the flows to changes in the unemployment rate and employment-population ratio.
