Hello, how do I appropriately weight the CPS Job Tenure Supplement base population when linking to the next month’s basic CPS?
There is no official guidance from the Census Bureau or BLS on how to apply weights to this type of analysis. I would recommend creating your own longitudinal weight that is based on JTSUPPWT.
In general, users should apply the most restrictive weight to their analysis. In this case, JTSUPPWT is more restrictive than LNKFW1MWT, since it adjusts for the probability of remaining in the CPS long enough to be part of the Job Tenure Supplement, and the probability of meeting the criteria of the Job Tenure Supplement (age and employment status). JTSUPPWT should be used with any analysis that uses variables from the Job Tenure Supplement.
JTSUPPWT should also be adjusted for the probability of being observed in the CPS two months in a row. This is necessary because some respondents drop out of the CPS due to moving, nonresponse, or other reasons between the two observation points you are using. You can modify JTSUPPWT to be a longitudinal weight by raking it. You will need to review the do file linked on this page on linking and the CPS and determine how to modify it. In the Stata script, you will need to replace WTFINL with JTSUPPWT for t1, and keep WTFINL for t2.
