4Last Wednesdays Experiment
- You have been asked to serve on a jury on a
lawsuit dealing with personal injury. In the
case before you, a 50-year-old construction
worker was injured on the job due to the
negligence of his employer. As a result, this
man had his right leg amputated at the knee. Due
to this disability, he cannot return to the
construction trade and has few other skills with
which he could pursue alternative employment. - The negligence of the employer has been firmly
established, and health insurance covered all of
the related medical expenses. Therefore, your
job is to determine how to compensate this worker
for the loss of his livelihood and the reduction
in his quality of life.
5What were we trying to test?
The other half were asked
Half of you were asked
- Should the plaintiff in this case be awarded more
or less than 10,000? - How much should the plaintiff receive? (Please
give a number.) - Are you male or female?
- Should the plaintiff in this case be awarded more
or less than 10,000,000? - How much should the plaintiff receive? (Please
give a number.) - Are you male or female?
- Testing how much did the suggestion in question
(a) affect the answers to question (b)?
6So, did the first question make a difference?

11What do we learn?
- Nobody knows exactly what a leg is worth
- Even among people asked exactly the same
question - answers varied from 20,000 to 1,000,000, or
from 0 to 50,000,000 - So theres an incentive to fight!
- Since no one knows the right answer,
suggestions matter - Higher suggestion raised average from 400,000 to
7 MM! - Reference point bias
- Framing effects
12A couple variationson liability
13Vicarious Liability
- Vicarious liability is when one person is held
liablefor harm caused by another - Parents may be liable for harm caused by their
child - Employer may be liable for harm caused by
employee - Respondeat superior let the master answer
- Employer is liable for torts of employee if
employee was acting within the scope of his
employment
14Vicarious Liability
- Gives employers incentive to...
- be more careful who they hire
- be more careful what they assign employees to do
- supervise employees more carefully
- Employers may be better able to make these
decisions than employees - and employees may be judgment-proof
15Vicarious Liability
- Vicarious liability can be implemented through
- Strict liability rule employer liable for any
harm caused by employee (as long as employee was
acting within scope of employment) - Negligence rule employer is only liable if he
was negligent in supervising employee - Which is better? It depends.
- If proving negligent supervision is too hard,
strict vicarious liability might work better - But an example favoring negligent vicarious
liability
16Joint and Several Liability
- Suppose you were harmed by accident caused by two
injurers - Joint liability you can sue them both together
- Several liability you can sue each one
separately - Several liability with contribution each is only
liable for his share of damage - Joint and several liability you can sue either
one for the full amount of the harm - Joint and several liability with contribution
the one you sued could then sue his friend to get
back half his money
17Joint and Several Liability
- Joint and several liability holds under common
law when - Defendants acted together to cause the harm, or
- Harm was indivisible (impossible to tell who was
at fault) - Good for the victim, because
- No need to prove exactly who caused harm
- Greater chance of collecting full level of
damages - Instead of suing person most responsible, could
sue person most likely to be able to pay
18Punitivedamages
19Inconsistency of damages
- Damage awards vary greatly across countries, even
across individual cases - We saw last week
- As long as damages are correct on average, random
inconsistency doesnt affect incentives (under
either strict liability or negligence) - But, if appropriate level of damages isnt
well-established, more incentive to spend more
fighting
20One problem with inconsistent damages more
incentive to fight hard
- Example each side can hire cheap lawyer or
expensive lawyer - Cheap lawyer costs 10, expensive lawyer costs
45 - If two lawyers are equally good, expected
judgment is 100 - If one is better, expected judgment is doubled or
halved

21Punitive damages
- What weve discussed so far compensatory damages
- Meant to make victim whole/compensate for
actual damage done - In addition, courts sometimes award punitive
damages - Additional damages meant to punish injurer
- Create stronger incentive to avoid initial harm
- Punitive damages generally not awarded for
innocent mistakes, but may be used when injurers
behavior was - malicious, oppressive, gross, willful and
wanton, or fraudulent
22Punitive damages
- Calculation of punitive damages even less
well-defined than compensatory damages - Level of punitive damages supposed to bear
reasonable relationship to level of
compensatory damages - Not clear exactly what this means
- U.S. Supreme Court punitive damages more than
ten times compensatory damages will attract
close scrutiny, but not explicitly ruled out
23Example of punitive damages Liebeck v McDonalds
(1994) (the coffee cup case)
- Stella Liebeck was badly burned when she spilled
a cup of McDonalds coffee in her lap - Awarded 160,000 in compensatory damages, plus
2.9 million in punitive damages - Case became poster child for excessive damages,
but
24Liebeck v McDonalds (1994)
- Stella Liebeck dumped coffee in her lap while
adding cream/sugar - Third degree burns, 8 days in hospital, skin
grafts, 2 years treatment - Initially sued for 20,000, mostly for medical
costs - McDonalds offered to settle for 800
- McDonalds serves coffee at 180-190 degrees
- At 180 degrees, coffee can cause a third-degree
burn requiring skin grafts in 12-15 seconds - Lower temperature would increase length of
exposure necessary - McDonalds had received 700 prior complaints of
burns, and had settled with some of the victims - Quality control manager testified that 700
complaints, given how many cups of coffee
McDonalds serves, was not sufficient for
McDonalds to reexamine practices
25Liebeck v McDonalds (1994)
- Rule in place was comparative negligence
- Jury found both parties negligent, McDonalds 80
responsible - Calculated compensatory damages of 200,000
- times 80 gives 160,000
- Added 2.9 million in punitive damages
- Judge reduced punitive damages to 3X
compensatory, making total damages 640,000 - During appeal, parties settled out of court for
some smaller amount - Jury seemed to be using punitive damages to
punish McDonalds for being arrogant and uncaring
26What is the economic purpose of punitive damages?
- Weve said all along with perfect compensation,
incentives for injurer are set correctly. So why
punitive damages? - Example
- Suppose manufacturer can eliminate 10 accidents a
year, each causing 1,000 in damages, for 9,000 - Clearly efficient
- If every accident victim would sue and win,
company has incentive to take this precaution - But if some wont, then not enough incentive
- Suppose only half the victims will bring
successful lawsuits - Compensatory damages would be 5,000 company is
better off paying that then taking efficient
precaution - One way to fix this award higher damages in the
cases that are brought
27This suggests
- Punitive damages should be related to
compensatory damages, but higher the more likely
injurer is to get away with it - If 50 of accidents will lead to successful
lawsuits, total damages should be 2 X harm - Which requires punitive damages compensatory
damages - If 10 of accidents lead to awards, damages
should be 10 X harm - So punitive damages should be 9 X compensatory
damages - Seems most appropriate when injurers actions
were deliberately fraudulent, since may have been
based on cost-benefit analysis of chance of being
caught
28How should we think about the legal process
itself?
27
29Over the last three months, we have
- Developed theories of property/nuisance law,
contract law, and tort law - Looked at how rules of legal liability create
incentives - Thought about how these rules can be chosen to
try to achieve efficient outcomes
30Weve been thinking of normative goal of
minimizing social costs
- Property law
- Goal was to allocate resources/entitlements
efficiently - or, to minimize inefficiencies due to
misallocation - Contract law
- Goal was to further facilitate trade
- or, to decrease inefficiencies due to unrealized
Kaldor-Hicks improvements - Tort law
- Goal was explicitly to minimize social costs
- which consist of cost of accidents plus cost of
precaution
31Implicitly, weve generally been assuming two
things so far
- The legal system works flawlessly
- Whatever theoretical goal we set, we can
implement correctly - (In tort law, weve considered effect of errors)
- The legal system costs nothing
- Gave us nice theoretical results for achieving
efficiency - Example injunctions when TC low, damages when TC
high - Example strict liability when injurer activity
matters a lot negligence when both sides
precaution matters a lot - Next what additional concerns are there when
trying to put a legal structure in place to
enforce these ideas?
32What is the goal of the legal system itself
i.e., how we implement the rules we chose?
- Start with the best possible benchmark
- Theoretically perfect rules, implemented
flawlessly and costlessly - Thats obviously the best we can hope to do
- How does reality differ?
- 1. Rules actually implemented wont be the
perfect ones - Imperfect rules will lead to imperfect
incentives, leading to less-than-perfectly-effici
ent actions and outcomes - Think of any loss of efficiency due to
imperfections in legal system as error costs - 2. Actual system wont be costless
administrative costs - Goal of legal system minimize sum of these two
costs
33Administrative costs and error costs
- Administrative costs
- Hiring judges, building courthouse, paying
jurors - More complex process ? higher cost
- Error costs
- Any legal process is imperfect
- Errors are any judgments that differ from
theoretically perfect ones - An error in computing damages after the fact only
affects distribution, not efficiency - But anticipated errors affect incentives, which
may lead to actions which arent efficient - Error costs are costs of distortions in actions
people take (precaution, activity levels, etc.)
due to flaws in legal system
34The goal of the legal process
- So theoretically, the efficient legal process is
the one that minimizes the sum of - The direct costs of administering the system, and
- The economic effects of errors due to process not
being perfect - Weve already seen the tradeoff between these two
types of costs - Tradeoff between simpler versus more complex
rules - Weve seen this several times
35Weve already seen tradeoff between
administrative and error costs
- Whaling law fast fish/loose fish vs.
iron-holds-the-whale - FF/LF lower administrative costs (fewer
disputes) - IHTW lower error costs (better incentives for
whaling) - Pierson v. Post (fox hunt case)
- Majority first to catch, otherwise fertile
source of quarrels - Dissent first to chase, hunting foxes is
meritorious - Privatizing ownership of land
- Expanding property rights adds admin costs
(boundary maintenance) - But lowers error costs (better incentives for
efficient use of resource) - Demsetz privatize when gains outweigh costs
- Same as pick system with the lower sum of admin
error costs
36Another application how costly should it be to
sue somebody?
- Worth it for victim to sue if
Expected value of legal claim
Cost toinitiatelawsuit
gt
- Probability of winning at trial, times expected
judgment - Or likelihood of a settlement, times expected
amount - Minus costs expected to be incurred
37Filing fees
- Expected value of claims should vary widely
Probability
Filing Fee
SUE
DONTSUE
Expected value of claims
38So what level of filing fees is efficient?
- The efficient legal system minimizes the sum of
administrative costs and error costs - Higher filing fees ? fewer lawsuits ? lower
administrative costs - But, higher filing fees ? more injuries go
unpunished - ? greater distortion in incentives ? higher
error costs - Filing fee is set optimally when these balance on
the margin - Marginal cost of reducing fee marginal benefit
- Administrative cost of an additional lawsuit
error cost of providing no remedy in the marginal
case
39How high should filing fees be?
- Error costs
- If were only concerned with efficiency, we dont
care about distributional effects - That is, we dont care if a particular victim is
or isnt compensated - So the size of error costs depends on how much
peoples behavior responds to the incentives
caused by liability - The social value of reducing errors depends on
whether the errors affect production or merely
distribution - When errors have large incentive effects, filing
fees should be low - When errors have small incentive effects,
efficiency requires higher filing fees
40Class Action Lawsuits
Probability
Cost to initiate lawsuit
SUE
DONTSUE
Expected value of claims
- As long as there is any cost to litigation, some
harms will be too low to justify a lawsuit - When harm is small to each individual but large
overall, one solution is a class action lawsuit
41Class Action Lawsuits
- One or more plaintiffs bring lawsuit on behalf of
a large group of people harmed in a similar way - Example California lawsuit over 6 bounced-check
fee - Court must certify (approve) the class
- Participating in a class-action suit eliminates
victims right to sue on his own later - If suit succeeds, court must then approve
plaintiffs proposal for dividing up the award
among members of the class - Class-action suits are desirable when individual
harms are small but aggregate harms are large - Especially when avoidance of liability has strong
incentive effect - But theres also a danger
42Some empirical observations about tort system in
the U.S.(might not get to)
Skip
41
43U.S. tort system
- In 1990s, tort cases passed contract cases as
most common form of lawsuit - Most handled at state level in 1994, 41,000 tort
cases resolved in federal courts, 378,000 in
state courts in largest 75 counties - Most involve a single plaintiff (many contract
cases involve multiple plaintiffs) - Among tort cases in 75 largest U.S. counties
- 60 were auto accidents
- 17 were premises liability (slip-and-fall in
restaurants, businesses, government offices,
etc.) - 5 were medical malpractice
- 3 were product liability
44U.S. tort system
- Punitive damages historically very rare
- 1965-1990, punitive damages in product liability
cases were awarded 353 times - Average damage award was 625,000, reduced to
135,000 on appeal - Average punitive damages only slightly higher
than compensatory - In many states, punitive damages limited, or
require higher standard of evidence - Civil suits generally require preponderance of
evidence - In many states, punitive damages require clear
and convincing evidence
45U.S. tort system
- Medical malpractice
- New York study in 1980s 1 of hospital
admissions involved serious injury due to
negligent care - Some estimates 5 of total health care costs are
defensive medicine procedures undertaken
purely to prevent lawsuits - Some states have considered caps on damages for
medical malpractice
46U.S. tort system
- Product liability
- Recent survey of CEOs liability concerns caused
47 of those surveyed to drop one or more product
lines, 25 to stop some research and development,
and 39 to cancel plans for a new product. - Liability standard for product-related accidents
is strict products liability - Manufacturer is liable if product determined to
be defective - Defect in design
- Defect in manufacture
- Defect in warning
47Vaccines
- Most vaccines are weakened version of disease
itself - Make you much less likely to acquire the disease
- But often come with very small chance of
contracting disease directly from vaccine - Salk polio vaccine wiped out polio, but caused 1
in 4,000,000 people vaccinated to contract polio - 1974 case established maker had to warn about
risk - Since then, some people were awarded damages
after their children developed polio from vaccine - If liability cant be avoided, built into cost of
the drug - And discourages companies from developing vaccines
48To wrap up tort law, a funny story from Friedman
A tort plaintiff succeeded in collecting a
large damage judgment. The defendants
attorney, confident that the claimed injury was
bogus, went over to the plaintiff after the
trial and warned him that if he was ever seen
out of his wheelchair he would be back in court
on a charge of fraud. The plaintiff replied
that to save the lawyer the cost of having him
followed, he would be happy to describe his
travel plans. He reached into his pocket and
drew out an airline ticket to Lourdes, the
site of a Catholic shrine famous for miracles.
