Sophie’s Choice
You are a member of a hospital’s ethics committee. You have to choose between allocating a kidney to an alcoholic former sports idol or a mother of two.

Paretian norms don’t work—if it’s an external cost
Externalities and Tort Law
What happens if third parties can’t be joined?
31
Do we then abandon the concept of efficiency?
A more relaxed standard: Kaldor-Hicks efficiency
A transformation is Kaldor-Hicks efficient when the winners could compensate the losers (“Potential Pareto-Efficiency”) and satisfy Paretian standards
But nearly everything has third party effects…

It is proposed to abandon steel tariffs that impose costs of $10B on the economy but provide steel manufacturers with a gain of $1B.
The bankruptcy of a failing business imposes a cost to shareholders of $1M, but provides a benefit of $5M to creditors.

Relaxing the Rationality Assumption: Transitivity: A Technical Definition
If A is preferred to B and B is preferred to C, then A is preferred to C
A}B, B}C A}C
42
Relaxing the Rationality Assumption: Transitivity: A Technical Definition
If A is indifferent to B and B is indifferent to C, then A is indifferent to C

45
Relaxing the rationality assumption:Paternalism
Suppose that, lacking perfect rationality, we knew that our choices might harm us.
Might we not, in such cases, wish to let the paternalist choose for us?
46
Relaxing the rationality assumption:Byron, The Prisoner of Chillon
At last Men came to set me free –I asked not why, and recked not where--It was at length the same to me,Fettered or fetterless to be--I learned to love despair…
My very chains and I made friends,So much a long Communion tendsTo make us what we are, even I Regained my freedom with a sigh

What happened?

Infants: Kiefer
What happened? The Wisconsin statute’s version of
restatement § 14 referred to 21 years as the standard. Was that dispositive? Should it have been?
48
Infants: Kiefer
What about the mature 16 year old? And the immature 25 year-old? Or the married person under the age of majority? The evidence from criminal law.

Did the Δ know that the Π was an emancipated minor? Does that matter?
51
Infants: Kiefer
Did the Δ know that the Π was an emancipated minor? Does that matter? Contrast Restatement §§ 14 and 15(2).
