BoardEx–DIME Crosswalk

In my paper “The Political Transformation of Corporate America, 2001–2022” (available here), I use supervised machine learning to merge two widely used datasets: BoardEx, which contains data on corporate directors an executives, and the Database on Ideology, Money in Politics, and Elections (DIME), which contains data on campaign contributions and ideology scores for campaign donors in the United States. I have made the crosswalk linking these two databases freely available for anyone to use.

You can download the crosswalk here.

NB: The current version of the crosswalk links to v3.1 of DIME. Adam Bonica recently updated DIME to v4.0, which contains different donor IDs. The crosswalk will not work with v4.0. A new version of the crosswalk that maps onto v4.0 is currently in progress and will be released once validated. If you want a preliminary version of the new crosswalk, please email me. Otherwise, if you use the current public version of the crosswalk, make sure you use v3.1 of DIME.

If you use the crosswalk, please cite: Steel, Reilly S. 2024. "The Political Transformation of Corporate America, 2001-2022." Columbia Law and Economics Working Paper No. 4974868. URL: https://ssrn.com/abstract=4974868.

I’d love to hear about how you’re using the data, so please feel free to shoot me a note and let me know!
