Dataset for Manually Coded Firm Founding Dates, CEO Duality, and CEO Photograph Prominence in Annual Reports

In this dataset, we wish to make available some measures which we manually coded as part of our PhDs. It contains manually coded information on S&P1500 firms and their CEOs, specifically, the firm’s founding year, whether the CEO is simultaneously chairperson of the board (CEO duality), and the prominence of the CEO in photographs in the firm’s annual report. More information can be found in the attached documentation. Both authors contributed equally to the creation of this dataset.

Since this is the first version of this dataset, we are happy about any feedback, corrections, or additions. Please reach out to us in case you spot any irregularities or have questions via mappels@mail.uni-mannheim.de or mkowalzi@staff.mail.uni-mannheim.de. 

The creation of this dataset was supported by the Fellowship Freies Wissen of the Wikimedia Foundation. More information on the project can be found here.
