FIN 7340 Corporate Theory II Dr. Nina Baranchuk Boards of Directors as an Endogenously Determined Institution Benjamin E. Hermalin Michael S. Weisbach Presented by: Michael Keefe January 18, 2006
“The directors of [joint stock] companies, however, being the managers rather of other people’s money than of their own, it cannot well be expected, that they should watch over it with the same anxious vigilance [as owners]....Negligence and profusion, therefore, must always prevail, more or less, in the management of the affairs of such a company” Adam Smith -1776
Key Questions • How do board characteristics or size affect profitability? • How do board characteristics affect observable actions of the board? • What factors affect the makeup of boards and how do they evolve over time?
Introduction – Survey Paper • Definition – An economic institution that, in theory, helps to solve agency problems inherent in managing an organization. • Formal theories limited • Major Conflict – Between CEO and Board • Significant empirical work, but little motivated by theory
Empirical Regularities • Composition (insider/outsider ratio) does not imply profitability • Number of directors is inversely related to performance • Board actions are related to board decisions( insider/outsider ration is related toPoison Pills, Acquisitions, Compensation) • Boards evolve relative to bargaining position of CEO
Why are there boards? • Regulation Driven – • Boards pre-date regulations • Larger than required by law • Hypothesis • Market solution to an agency problem • Endogenously determined institution • Provides contracts and incentives to management • Shleifer and Vishny (1986) – Free-Rider problem alleviated by large outside shareholder. Power of shareholder works through board. • Meissner (2000) – Side payments greater than gains for bad loans.
What do they do? • Outside Director as a Monitor • Fama (1980), Fama and Jensen(1983) – build reputation as expert monitor • Kaplan and Reishus (1990) – build reputation as doesn’t make trouble • Hermalin and Weisbach (1998) Board Specific Model • Board decides to keep or fire CEO • CEO ability linked to performance • CEO prefers less independent board • CEO bargaining power related to performance
Hermalin and Weisbach Predictions 1* Poor performance=>increase probability of replacement 2* Board independence => higher CEO turnover 3* Poor performance => more independent directors 4* CEO tenure=>less board independence 5* Accounting measures better predictor of tenure than stock performance 6 Long Term persistence in corporate governance 7 CEO fired • Private information => negative return • Public Information => positive return 8 CEO Salary • Low Levels of Performance => limited affect to salary • High Levels of Performance => affects salary * Strong empirical support
Empirical Issues • System • Actionst+s= φCharacteristics + ε • Profitst+s = βActions + η • Characterisitcst+s = μProfits + ξ • Equilibrium or Out-of-Equilibrium? • Methods • Typically not jointly estimated • Endogeneity handled with lags
Tobin's q • Tobin's q = market value / asset value • If the market value = asset value => Tobin's q= 1.0. • If Tobin's q > 1.0, then market value > than the value of the company's recorded assets. • Tobin's q reflects a number of variables, and in particular: • The recorded assets of the company. • Market sentiment, reflecting, for example, analysts' views of the prospects for the company, or speculation such as bid rumors. • The intellectual capital of the company.

Outside Directors and Performance • Method: Contemporaneous Correlations with accounting measures and Tobin q • Results: No Evidence supporting outside directors and performance • Issue: Endogeneity – Poor performance leads to independent boards (Hermalin and Weisbach 1998) • Method1: Lagged Performance as instrument for current performance • Results1: No Evidence supporting outside directors and performance • Method2: Rosenstein and Wyatt (1990) use event study for outside directors added to board • Result2: Some evidence - .2% increase in return • Benefit of Method: Controls for all firm specific effects
Board Size and Performance • Jensen (1993) and Lipton and Lorsch (1992) suggest increase board size leads to agency problems • Yermack (1996) – Negative Relation between board size and Tobin’s q • Gertner and Kaplan (1996) Study: Board sizes of reverse leverage buyouts Method:board size smaller than comparable firm • Equilibrium or out of equilibrium – Why hasn’t economic darwinism eliminated the unfit organizational form?
Board Size and Tasks (actions as a function of characteristics) • CEO Turnover • Findings: Robust relationship between turnover and performance • Empirical issue – voluntary or non-voluntary • Weisbach (1988)- • Approach: interacts board composition with firm performance • Finding: CEO turnover more sensitive to firm performance with outside directors. • Robust to performance as measured by accounting or market measures • CEO turnover with insider dominated boards not performance sensitive • Yermack (1996) and Wu (2000) – Interact board size with performance and find smaller boards are more effective overseers of CEOs. • Perry (2000) – Incentive pay also significant
Evidence from Takeover Market • Shivdasani (1993) – • Question: probability of takeover in a hostile bid? • Finding: Additional directorships => lower probability • Why? • Cotter et al. (1997) • Question: Relationship between return from hostile takeover and outside directors • Result: Majority of outside directors=>20% increase in return. • Harford (2000) – Documents pecunary interests of directors to resist a takeover. • Byrd and Hickman (1992) • Question: Relationship between return when acquiring • Results: • -1.33% abnormal return for entire sample • -.07% abnormal return if 50% of directors outside • -1.86% abnormal return if minority of directors outside
Poison Pills • Effect can be argued both ways: • Protect Management • Increase bargaining position • Brickley et al. (1994) • Method: Split sample, analyzed market reaction • Results: Poison Pill Announcements=> • Decrease in price if majority inside directors • Increase in price if majority of outside directors
Executive Compensation • Core et al. (1999) • Results: Weaker goverance => Higher CEO pay • Measures: • Outsiders appointed by CEO • Directors over 69 • Board Size • Busy Directors (additional directorships) • Interlocking Directors • Yermack (1996) – pay for performance increases with small boards
Board Dynamics • Changes in a firm’s characteristics =>changes in board composition • Hermalin and Weisbach (1988) • Poor Performance => more outside directors • CEO succession imminent => more inside directors • Firm leaves a product market => inside directors depart
CEO Power Struggle with Board • Fundamentally Unobservable • Approaches • Hallock (1997 1999) - Interlocking directorships • Shivdasani and Yermack (1999) – board selection process (e.g. seperate nominating commitee) • Baker and Gompers (2000) – CEO voting stake => board selection in IPO
Industry Studies • Hospitals – non-profits and for-profit hospitals • Brickley and Van Horn (2000) – can’t reject that both types maximize the same objective function • Eldenberg et al. (2000) – find sensitivity to CEO turnover related to hospital performance, high admin costs, and high levels of uncompensated care vary by hospital type.
Future Research Directions • Model inner workings of boards • Test implications of models • Study different type of boards – nonprofits, smaller firms, etc.
