  1. Fairness Norms and Self-interest in VC/E Contracting: A Behavioral Game-theoretic Approach • Existing VC/E Financial Contracting Models assume narrow self-interest. • Double-sided Agency problems (both E and VC exert Value-adding Effort) (Casamatta JF 2003, Repullo and Suarez 2004, Fairchild JFR 2004). • Procedural Justice Theory: Fairness and Trust important. • No existing behavioral Game theoretic models of VC/E contracting.

  2. My Model: • VC/E Financial Contracting, combining double-sided Moral Hazard (VC and E shirking incentives) and fairness norms. • 2 stages: VC and E negotiate financial contract. • Then both exert value-adding efforts.

  3. How to model fairness? Fairness Norms. • Fair VCs and Es in society. • self-interested VCs and Es in society. • Matching process: one E emerges with a business plan. Approaches one VC at random for finance. • Players cannot observe each other’s type.

  4. Timeline • Date 0: VC makes ultimatum offer of equity stake to E; • Date 1: VC and E exert value-adding effort in running the business • Date 2 Success Probability • => income R. • Failure probability • =>income zero

  5. Expected Value of Project • Represents VCs relative ability (to E).

  6. Fairness Norms • Fair VC makes fair (payoff equalising) equity offer • Self-interested VC makes self-interested ultimatum offer • E observes equity offer. Fair E compares equity offer to social norm. Self-interested E does not, then exerts effort.

  7. Expected Payoffs If VC is fair, by definition,

  8. Solve by backward induction: • If VC is fair; • Since • for both E types. • => • =>

  9. VC is fair; continued. • Given Optimal Effort Levels: Fair VC’s equity proposal (equity norm):

  10. VC is self-interested: • From Equation (1), fair E’s optimal effort;

  11. Self-interested VC’s optimal Equity proposal • Substitute players’ optimal efforts into V= PR, and then into (1) and (2). Then, optimal equity proposal maximises VC’s indirect payoff =>

  12. Examples; • VC has no value-adding ability (dumb money) => • => • r =0 => • r => 1 ,

  13. Example 2 • VC has equal ability to E; => • r =0 => • r => 1 , • We show that as r => 1
