CPS CEPR: ORG and Monthly

How does the CPS CEPR store employment information for the non-ORG months?

I am trying to reproduce Mueller (2012). He says

The CPS is the main labor force survey for the U.S., representative of the population aged 15 and older. It has a rotating panel structure, where households are surveyed in four consecutive months, rotated out of the panel for eight months, and then surveyed again for another four consecutive months.

But it also says

Note that the CPS records the labor-force status for each person in the sample each month. Weekly hours and earnings, however, are collected only in the fourth and eighth interview of the survey,

This means that the CEPR has

• ORG files that contain the wages
• monthly files that contain labor force status

On the CEPR Monthly site, it says that

The CPS Basic Monthly data variables are incorporated into CEPR CPS ORG data.

Which means that I only have to download the CEPR ORG data. Sounds like good news.

I downloaded 2013 and 2014 from here. Minsamp corresponds to the monthly interview, the variable has unique values 4 and 8 (which are the outgoing interview months). So far, so good. There is an empl variable which appears to encode employment status. However, I cannot find the employment status for other months than the interview months. I can't find neither additional rows, which would carry that information in long form, nor additional columns, which could carry it in wide form.

Here's how some data extract (restricting some columns and rows) looks:

As you can see, for every unique household member (every hhid-hhid2-lineno combination), there is only one row. And if its somehow stored in the wide format, I'd expect the name to contain 'emp' somewhere:

... [x for x in df.columns if 'emp' in x]
['empl', 'unempt', 'selfemp', 'pdemp1', 'pdemp2', 'nmemp1', 'nmemp2']


where the first four correspond to the individuals employment status (but not in different months), and the last for correspond to the number of employees linked to the individual (and similar).

Clearly, the information must be there somewhere. So, How does the CPS CEPR store employment information for the non-ORG months?
