Economics of Contract Law
Agency Game I
Give me $100 and I’ll turn it into $200 and share the gain with you
Do you trust me? No! Player 2 has DS to breach
Player 2
Perform
Contract Player 1 Don’t Contract 150, 50 100, 0
Breach
0, 200 100, 0
Solutions?
Reputation in a repeated game Contract law
Agency Game II
Suppose we sign a contract in which I am punished if I run off with the money
Court forces me to pay you $150 and charges each of us an additional $25 fee for doing so
Player 2
Perform
Contract Player 1 Don’t Contract 150, 50 100, 0
Breach
125, 25 100, 0
1st Purpose of Contract Law is to enable people to cooperate
Requires a way to make a promise credible (some sort of commitment)
Example 1
The rich uncle of a struggling college student learns at the graduation party that his nephew graduated with honors. Swept away by good feeling, the uncle promises the nephew a trip around the world. Later the uncle reneges on his promise. The student sues his uncle, asking the court to compel the uncle to pay for a trip around the world.
Example 2
One neighbor offers to sell a used car to another for $1000. The buyer gives the money to the seller, and the seller gives the car keys to the buyer. To her great surprise, the buyer discovers that the keys fit the rusting Chevrolet in the back yard, not the shiny Cadillac in the driveway. The seller is equally surprised to learn that the buyer expected the Cadillac. The buyer asks the court to order the seller to turn over the Cadillac.
Example 3
A farmer, in response to a magazine ad for “a sure means to kill grasshoppers,” mails $25 and receives in the mail two wooden blocks with the instructions, “Place grasshopper on Block A and smash with Block B.” The buyer asks the court to require the seller to return the $25 and to pay $500 in punitive damages.
Bargain Theory of Contracts I
A promise should be enforced if it was given in a bargain, otherwise it should not.
Offer Acceptance Consideration
Promisor: person who gives a promise Promisee: person who receives it
“reciprocal inducement”
Rich uncle: no consideration offered Disputed car: no “meeting of the minds” Grasshopper killer: enforceable bargain
How do you enforce a gift promise?
Bargain Theory of Contracts II
What should the remedy be for broken promises?
Expectations damages: amount promisee could
reasonably expect from performance
Problems with the Bargain Theory
Requires all promises to have consideration
Car shopping and a “firm offer”
Requires that all bargains be enforced
Grasshopper killer?
Economic efficiency requires enforcing a promise that both parties want enforced.
Economic Theory of Contract
1st Purpose of Contract Law is to enable people to cooperate Rich uncle: both want the promise enforced Disputed car: no cooperative surplus Grasshopper killer: enforce the promise to discourage deceit by promisor
2nd Purpose of Contract Law is to encourage efficient disclosure of information
Used car market
You value my car 50% more than I do Asymmetric information exists No mechanics
[0---------------------------5000]
$2500 (your guess as to value of car to me)
Suppose you offer $3000
$1500 (your revised guess as to value of car to me)
[0-------------------3000]
You will end up paying $3000 for a car that’s only worth $2250 to you
3rd Purpose of Contract Law is to secure optimal commitment to performing.
What should be the remedy for efficient breach?
Painting sale
You value my unfinished painting at $1000 We agree on a sale price of $600 upfront Crazy cousin makes $5000 offer It’s efficient for me to breach contract with you:
Cost of performance > benefit you will get from the painting
Airplane sale
You value my plane at $500,000 We agree on a sale price of $350,000 Before construction begins, price of metal rises and raises my cost to $1,000,000
3rd Purpose of Contract Law is to secure optimal commitment to performing.
Optimal Performance
If promisor’s cost of performing > promisee’s benefit from performing, then breach is efficient If promisor’s cost of performing < promisee’s benefit from performing, then performance is efficient
Choice of remedy is critical
If penalty for breach is too severe, the promisor will have to perform, even though breach may be efficient If penalty for breach is too weak, the promisor will breach when efficiency requires performance
3rd Purpose of Contract Law is to secure optimal commitment to performing.
Actual Performance Decision:
If promisor’s cost of performing > promisor’s liability for breaching, then he will breach If promisor’s cost of performing < promisor’s liability for breaching, then he will perform
Perfect Expectations Damages
Promisor’s liability = promisee’s benefit from performance Restores promisee to position he would have enjoyed if promise had been kept
Painting Sale I
You value my unfinished painting at $1000 We agree on a sale price of $600 upfront Crazy cousin makes $5000 offer
Buyer Buy Perform Painter 600, 400 -400, 5400 4600, 400 5600, - 600 Don’t Buy ------
Breach
------
What are Expectation Damages?
DE = $1000 What if D = $6000
Painter breaches and it is efficient
Painter performs though breach is efficient
Painting Sale II
You value my unfinished painting at $1000 We agree on a sale price of $600 upfront Crazy cousin makes $5000 offer Assume simple DE Buyer purchases frame for $50 which raises value of painting to $1200
Buyer Rely Perform Painter Breach 600, 550 4400, 550 Don’t Rely 600, 400 4600, 400
Whether painter performs or not, reliance makes you better off But, is reliance efficient?
4th Purpose of Contract Law is to secure optimal reliance.
If Expected Gain from Reliance > Cost of Reliance then Reliance is efficient
p = probability of performance ∆V = increase in value of performance due to reliance c = cost of reliance If p(∆V) > C then reliance is efficient
Painter ex: ∆V = 200 c = 50
p* = 0.25
When the probability of performance is high, more reliance tends to be efficient
4th Purpose of Contract Law is to secure optimal reliance.
Warning: if my damages cover your benefit whether or not it’s efficient, then you’ll always spend on reliance (over-reliance) Solution: Perfection Expectations Damages
damages needed to restore the promisee had the promise been kept, and had he relied the optimal amount
Foreseeability Doctrine
“Reasonably expected” reliance
Hadley v Baxendale (1854)
Hadley ran a mill and crankshaft broke Baxendale was to deliver it to engineers
Delayed one week (used boat rather than rail)
Hadley sued for week’s worth of lost profits Court ruled lost profits were not foreseeable
5th Purpose of Contract Law is to minimize transaction costs of negotiating contracts by supplying efficient default rules Gaps: contract is silent about risks
Inadvertent gaps: not foreseeable Deliberate gaps: remote risks
Cost of allocating a risk > Expected cost of allocating a loss leave gap
Cost of allocating a risk < Expected cost of allocating a loss fill gap
Default rules
Compute hypothetical bargain
Who can bear risk at lowest cost? Adjust price of the contract
McGuire v Wabash
McGuires hire Wabash to build new house Price of copper rises by $2000 and contract is silent McGuires refuse to pay extra $2000 Suppose Wabash knows that copper costs could rise by $2000 with p = 0.50
Expected cost = (0.50)(2000) = $1000 Suppose Wabash could’ve hedged risk for $400
Hypothetical bargain
Who is the low cost bearer of risk? Wabash If risk was foreseeable, Wabash would charge extra $700
McGuires pays $700 Wabash absorbs $1300 loss
Perfect Contracts and Market Failures
Perfect Contract
All risks is efficiently allocated All relevant information is communicated All resources allocated to those who value it the most
Individual Irrationality
Incompetence Dire constraints
Necessity Duress
Transactions Costs
Spillovers Asymmetric information Monopoly
Exceptions to perfect contracts
6th Purpose of Contract Law is to foster enduring relationships, which solve the problem of cooperation with less reliance on the courts to enforce contracts
Coffee shop and the forgotten wallet Prisoner’s Dilemma
One-shot game: DS is to cheat Repeated game: Cooperative outcome is Pareto Optimal
“tit-for-tat” strategy
“Rarely will buyers leave saying they bought the wrong goods at too high Diamond Dealer’sis to make them eager to NY a price. Our goal Club come back. We offer a source which provides a competitive edge, all of which translates directly into increased profits.”
Endgame Problem
Peevyhouse v Garland Coal (1962)
Peevyhouse owned farm in Oklahoma Garland contracted to strip-mine coal
Contract specified that Garland would take steps to restore land to previous condition
Garland breached
Peevyhouse sued for $25,000 Restorative costs were estimated to be $29,000 at trial Garland showed that “diminished value” of farm was only $300
Original jury awarded $5000 to Peevyhouse OK Supreme Court reduced damages to $300
Efficient breach? Dissent: specific performance was warranted, otherwise no formation would have occurred
