Is it possible to link ASEC with CPS monthly files on NBER? I have read papers that describe how to link the ASEC to the CPS basic monthly, but these papers assume that the CPSID is available, which seems to only be true if you are downloading directly from the IPUMS CPS website. From what I can tell, the CPS basic monthly data on NBER’s website does not have a CPSID variable, so I assume this was constructed later. There are responses to questions that are not available on the general IPUMS CPS site that can only be found in the complete NBER microdata, which is why I need to link the ASEC with this specifically.
Any help would be greatly appreciated!
