An Evolutionary Risk Basis for theDifferential Treatment of Gains and Losses Venky Nagar MadhavRajan Korok Ray
Conservatism • Asymmetric Verification Standards • Recognize probable losses • Recognize surer gains
This study’s 3-step approach • Individuals display risk-aversion in gains, but risk-tolerance in losses They prefer a sure gain to a gain gamble They prefer a loss gamble over sure loss • Preferences drive demand for verification More verification for probable gains Less verification for probable losses 3. Accounting responds to this demand Conservatism
Prior Studies • Analytical studies • Empirical Studies • Reasoned conjectures on monitoring • Gigler et al. (2009) • Scott et al. (1926)
An Evolutionary Problem in Two Parts • First, hunt for food • Second, prevent a stealer from stealing it • Private information on “strength” state of the hunter • Equilibrium outcome: • Conservative in hunting • Aggressive in defending the catch • Hard-wired preference
Evolutionary Psychology • We house stone-age minds that are hardwired to solve evolutionary survival problems • How did this happen? • Gamma rays strike the earth • Errors in meiosis • Innate ability to deal with small numbers • Counting bears • Stock market • Is it all hocus-pocus? • God and the watchmaker
Model Basics The hunt • Prey size y • Benefit of catch B(y) The steal • Producer type θ = {WEAK, TOUGH} • Producer info Perfect • Stealer info Correct with probability qs
Back to the Modern World • What do the roles of stealer and producer mean today?
Conservatism • Utility function concave over gains and convex over losses implies: • Higher verification standard for gains than losses
Equilibrium Properties • Robust Nash Equilibrium • Evolutionarily stable • Hinges crucially on information asymmetry • Stealer does not know producer’s state as well as the producer does
Empirical Implications • Prior theory on conservatism • All about explicit contracting • Prior empirical research on conservatism • Anything but… • Private firms • R&D • Management ownership • SEO • Legal norms and institutions
Our Interpretation • Information asymmetry between managers and investors • Sharing is caring • All cross-sectional variation in conservatism • Loss side
Conclusion in Three Steps • Endogenous Preferences • Risk-aversion in gains, but risk-seeking in losses • Verification Implications • Lower verification standards in losses • Conservatism
