Chris Economics & Policy Flashcards
Kaldor-Hicks
The benefit would exceed the cost by some considerable margin
(“This person benefits so much that they could compensate this person for all their losses, and have plenty to spare.”)
The idea of a contract in Wonnell world
Converting what would otherwise be a Kaldor-Hicks efficient transaction into a Pareto efficient transaction.
Weeds out transactions that are inefficient.
(if you think X is worth 1 and doing it would cost me 2, we’re both gonna walk away; cannot be made mutually beneficial)
Pareto Efficiency
Making persons better off without making any persons worse off
Coase
Answers “What legal rule would result in an efficient handling, resolution of this problem?”
If transaction costs are 0 (or rather low enough to make a transaction practical), the parties will bargain around any inefficient rule & every legal rule will be efficient.
(If there’s a legal rule→Kaldor-Hicks BUT If you let people bargain→pareto)
Reality Check of Coase Theorem Application in Nuisance cases
After an injunction, people are not willing to bargain in the way that a simple coase theorem might suggest they would be.
It is not common for people to bargain around nuisance
[Wonnell Commentary: There could be issues with the interpretation of transaction costs or the theorem itself, but it’s more likely that by that point in the suit the parties just hate each other.]
Arguments: Why do we have duty to rescue over a contractual obligation?
Transaction costs, impracticality, no realistic chance of negotiating deals in emergencies
Counter Argument for: Why do we have duty to rescue over a contractual obligation?
Contracts would be Pareto efficient in a rescue scenario if 3rd parties aren’t adversely affected.
Theory Behind Restitution Plans
To avoid unjust enrichment of the ∆
- contracts are based on consent that you cannot always get
- establishes a quasi-contract between the parties to what they would have agreed to if they had been able to negotiate.
- mutually beneficial
What’s wrong with just requiring a duty to rescue?
raises issues of liberty (you have the right to do something else, and issues of long term utility
Long-Term Incentive Effects of an affirmative duty to rescue (Rescuers)
- Loses some incentive to become useful if by acquiring knowledge or being in a specific location they are conscripted to help others
Long-Term Incentive Effects of an affirmative duty to rescue (Rescuees)
- Loses some incentive to avoid needing rescue, allows π to act more recklessly
Solution to Efficiency POV
(Fear that you’ll invest too much in things that cause negative externalities & too little in things that cause positive externalities )
Contracts –> pay to positive; only works in low transaction costs
(other examples restitution, duty to rescue, tort law in general,
Property Rules
Sternly forbidden from violating the entitlement without consent
Ex: punitive damages, injunction
Liability Rules
Okay to violate entitlement if compensated after the fact
Ex: compensatory damages
Benefit of Property Rule
Sensitive to idiosyncratic or subjective value (eminent domain fair market value example) to avoid Monopoly/extortion threat
