This project was inspired by “The Problem of 12”, the fact that most public companies are increasingly being controlled by a small group of institutional investors: https://ssrn.com/abstract=3247337

There is compelling evidence that this shared ownership can lead to anticompetitive outcomes, such as lower wages and higher prices: https://ssrn.com/abstract=2427345.

My goal is to highlight the extent to which ownership of many competing companies is being concentrated among a small number of institutions, and spark discussion about this problem. Let me know if you have any suggestions for improvements to the dashboard, or ideas for new projects for me to work on!
