I’ve been using the original CPS from NBER, both basic monthly files and the ORG, for many of the work I do. One of the reasons why I was using the data from NBER is to match individual records from one month to the following.
However, it seems to me that this matching should also be possible using IPUMS-CPS directly. In general, I would like to know what is the advantage of using the data directly from the NBER (which implies hours of looking at documentation and the risk of errors during the extraction) over using IPUMS-CPS? What is it that IPUMS-CPS does not have?
