A Critical Review of the Common Ownership Literature
The rapid growth in index funds and significant consolidation in the asset-management industry over the past few decades has led to higher levels of common ownership and increased attention on the topic by academic researchers.

We find little evidence to support such a hypothesis, and show that the positive relationship between average ticket prices and a commonly used measure of common ownership previously documented in the literature is ...
