1 Interaction of voluntary disclosure and earnings management A theoretical perspective
2 2 ways to think about it How does voluntary disclosure affect/is affected by earnings management in mandatory reports? Do firms manage voluntary disclosures (such as earnings forecasts)? And, if so, how?
3 Modeling tools A simple model of earnings management (mandatory reports) Voluntary disclosure: the unraveling result how to overcome it Putting it together
4 Earnings Management A simple model max P( Ω) r - C(r,x) r -1 - r 2 1 x 2 Stock price Cost of earnings management FOC: 1 ( r x ) = 0 r(x) x 1 P(r) E[x ~ r] r -1 r: reported earnings x: true earnings true value of the firm is x
5 Earnings Management A simple model: Truthful reporting in equilibrium max P( Ω) - r C(r,x) r -1-2 r x Stock price Cost of earnings management r(x) x P(r) E[x ~ r] r r: reported earnings x: true earnings true value of the firm is x
6 Earnings Management A simple model: What are C(r,x)? Cost of discretionary accruals? Reputation? Litigation? Real earnings management costs? max P( Ω) r - C(r, x) Stock price Cost of earnings management r: reported earnings x: true earnings true value of the firm is x
7 Earnings Management A simple model: What are C(r,x)? max E [ x - C(r, x) r ] Cost of discretionary accruals? Reputation? Litigation? Real earnings management costs? Unmanaged earnings Cost of earnings management Stock price r: reported earnings x: true earnings true value of the firm is x
8 Earnings Management A simple model: Loss of information max P( Ω) - r b0 1 r-1 b r C(r, x, ) r x 2 Stock price Cost of earnings management FOC: b 1 ( r x η ) = 0 r(x) b1 x 2 P(r) E[x ~ x () r] x r b μ 1 x 2 2 x r: reported earnings x: true earnings true value of the firm is x
9 Earnings Management A simple model: Loss of information (cont.) max η* η*( b r) P( Ω) - r b0 1 Stock price - C(r,x) r 2 1 x 2 Cost of earnings management FOC: b 1 η ( r x ) = 0 r(x) b1 x 2 P(r) E[x ~ x () [ r] ] x r μ x b x 1 r: reported earnings x: true earnings true value of the firm is x
10 Earnings Management A simple model: Summary Significance of marginal costs Nature of misreporting costs Loss of information
11 Modeling tools A simple model of earnings management (mandatory reports) Voluntary disclosure: the unraveling result how to overcome it Putting it together
12 Voluntary Disclosure The unraveling result: How voluntary is voluntary disclosure? Unraveling Result Grossman (1981) Milgrom (1981) (1) Disclosures are costless Jovanovic (1982) Verrecchia (1983) (2) Investors know that firms have, in Dye (1985) fact, private information Jung/Kwon (1988) (3) Firms know how investors will interpret the disclosure (4) Managers want to maximize share price (5) Firms can credibly disclose their private information (6) Firms cannot commit ex-ante to a specific disclosure policy. Dutta/Trueman 2002 Fishman/Hagerty 2003 Einhorn (2007) Korn (2004) private information Beyer/Guttman (2012) Vives 1984 Goex/Wagenhofer 2009 Full disclosure Partial disclosure
