A new study shows that one of the chief benefits of private-equity firms is largely an illusion.
Where's the Shareholder Outrage at Hewlett-Packard?
Bloomberg Businessweek online
How have Hewlett-Packard (HPQ) shareholders largely remained so silent while board infighting, botched multi-billion-dollar acquisitions, multiple strategic false starts, and high C-Suite turnover have combined to lop off more than $90 billion of market valuation—the venerable tech company is now worth just $28 billion—since the end of 2009?
The Power of the 'Passive-Aggressive' Shareholder
There’s a case to be made that activist investors are great for both the shareholders and managers at companies they partially own but aren’t trying to take down.

I base my skepticism on an academic study published several years ago in the prestigious Journal of Financial Economics: “The Evolution of Capital Structure and Operating Performance after Leveraged Buyouts: Evidence from U.S. Corporate Tax Returns,” by Jonathan Cohn and Lillian Mills, both from the University of Texas at Austin, and Erin Towery of the University of Georgia.
We present evidence that financing frictions adversely impact investment in workplace safety, with implications for worker welfare and firm value. Using several identification strategies, we find that injury rates increase with leverage and negative cash flow shocks, and decrease with positive cash flow shocks. We show that firm value decreases substantially with injury rates. Our findings suggest that investment in worker safety is an economically important margin on which firms respond to financing constraints.
We use events related to a proxy access rule passed by the Securities and Exchange Commission in 2010 as natural experiments to study the valuation effects of changes in shareholder control. We find that valuations increase (decrease) following increases (decreases) in perceived control, especially for firms that are poorly performing, have shareholders likely to exercise control, and where acquiring a stake is relatively inexpensive.
This paper investigates the effects of analyst recommendations issued after a merger announcement on deal completion. We find the probability of completion increases (decreases) with the favorability of acquirer (target) recommendations. We also find that favorably recommended firms in a proposed merger underperform following deal resolution, suggesting that investors overreact to postmerger announcement recommendations.
[Recepient of Charles River Assoc. Award for the Best Paper on Corporate Finance, 2012 Western Finance Assoc.] This study uses corporate tax return data to examine the evolution of firms' financial
structure and performance after leveraged buyouts (LBOs) for a comprehensive sample of

We provide a model of governance in which a board arbitrates between an activist
investor and a manager facing reputational concerns. The optimal level of internal board
governance depends on both the severity of the agency conflict and the strength of ...
