Since 2008, a massive shift has occurred from active towards passive investment strategies. This burgeoning passive index fund industry is dominated by BlackRock, Vanguard, and State Street, which we call the ‘Big Three’. In a new working paper CORPNET shows that already in 40 percent of all listed U.S. corporations the Big Three together constitute the largest shareholder — and even in 88 percent of the S&P 500 firms. This re-concentration of ownership is unprecedented and unlike the earlier ascent of actively managed mutual funds, such as Fidelity, is likely here to stay.

Private engagements with management represent an important channel through which the Big Three exert influence.
