Hello,

I know that many people have been able to link CPS data by CPSID but I was wondering what the process (i.e. commands) on STATA are? I am trying to replicate data from this paper " Health Insurance and the Supply of Entrepreneurs: Evidence from the ACA Medicaid Expansion" ([Health Insurance and the Supply of Entrepreneurs: Evidence from the ACA Medicaid Expansion by Kyung Min Lee :: SSRN](https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3462896)) and have struggled to successfully link the data in STATA.

Thank you!

Specifically I am trying to match ASEC data from 2004 to 2019 to create the one year longitudinal panels.

We have previously hosted a workshop dedicated to the process of linking CPS data. [Here are a list](https://cps.ipums.org/cps/cps_workshop2018_materials.shtml) of resources available from the workshop back in the summer of 2018. These resources include sample syntax for linking the data using Stata. Additionally, [applications are available](https://cps.ipums.org/cps/workshops.shtml) (and due by February 23) for another of these summer workshops if you’d like to attend in person.
