101: Existence

→ see learning outcomes

no conflict of interest → only coordination ⇒ Cheap Talk
whenever no conflict of interest → no contract, cheap talk is enough

Spot transaction (apple at market, after that you want nothing more of the seller, can inspect the good)
no contract needed

Game Tree (utility/payoff for each person)
once viper is saved → conflict of interest (viper prefers to bite)
very bad equilibrium as farmer does not save viper

  • viper could put muzzle, or remove tooth

Ex-Ante vs. Ex-Post perspective

  • prefers giving warranty before, to incentivise buyer
    • ex-post warranty is liability

Sequential Exchange → first mover is vulnerable / asymmetric information

  • contract allow us to move beyond cheap talk
    • liable to pay damage
    • contract makes us able to credibly commit

102: Enforcement

Why does the state want to enforce contracts

  • increases social welfare!
  • assumes parties knows their interests and have level of experience/knowledge
    • not enforced for infants/mentally ill / duress / misrepresentation → state does not enforce
    • externalities that hurt 3rd person → not enforced

State facilitates transactions / exchange → allows division of labor, via trade

  • the cheaper it is to trade, the more wealth

Why is contract structure important

  • leaving money on the table ⇒ transaction costs
  • by allowing warranty → they can trade
    • since seller knows good is of quality, she can offer warranty for free
    • value created

failure to find right contract → no transaction / high cost

103: Better Judge & Litigator

If contract is not performed → court and obtain legal remedy

  • legal remedy eliminates inefficiency

Default compensation:

  • expectation payment
    • puts the aggrieved party in as good a position as without breach

Damages may be hard to quantify (emotional, reputational damage)

  • court may award only fraction of cost
    if the VC expects the court not to award as much damage → would still breach

Liquidated damages clause

  • parties agree in advance a specified amount of money
    • court only need to see that breach occurred → force payment

but Liquidated damages clause will not always be enforced (common law courts do not enforce if they seem overcompensatory → see it as penalty clause (not enforceable)).

  • they might reduce to actual damages → breaching now attractive again
  • so we have to make the judge understand that the liquidated damages were ex—ante correct!
    • Counterfactual scenario

Should not strike down a clause because it looks excessive after the fact!

  • might have been useful ex-ante
