Date: Wednesday 28th January 2026 (updated)   Time: 18:30-20:00 GMT
Venue: Sheikh Zayed Theatre, Cheng Kin Ku Building, London School of Economics (map) (updated)
Speaker: Per Strömberg (Stockholm School of Economics)
Chair: Ulf Axelson (LSE Finance)

In this talk, Per Strömberg will present a simple economic framework for understanding the economic role of private equity.  

The framework helps answer questions such as:

  • Why would private equity ownership improve firm performance?
  • If PE is so superior, why are not all firms PE-owned?
  • Why don’t other owners and firms implement the same techniques as PE-owners do?
  • Can PE returns consistently outperform public equity markets?
  • Why is PE activity so cyclical?
