The first generic challenger to a branded drug tends to feature an investor base that has substantial stakes in the branded drug's manufacturer. Such ownership links between generic and brand also predict pay-for-delay settlements that delay generic competition in the brand's market in return...

We study in a highly abstract laboratory setting whether and how subjects in the role of shareholders use the stock market to monopolize product markets. We find that shareholders holding stakes in product market rivals choose compensation packages for subjects in the role of managers that...

The question of whether and how partial common-ownership links between strategically interacting firms affect firm objectives and behavior has been the subject of theoretical inquiry for decades. Since then, the growth of intermediated asset management and consolidation in the asset management...

This paper provides a framework for evaluating policy proposals aimed at invigorating competition and improving corporate governance amid a high and increasing level of common ownership of product market competitors. In particular, I propose that any effective proposal must have the effect of...

This paper shows that collateral constraints restrict entrepreneurial activity. Our empirical strategy uses variations in local house prices as shocks to the value of collateral available to individuals owning a house and controls for local demand shocks by comparing entrepreneurial activity of...
