Party-designed remedies
Court-imposed damages
Specific performance

Expectation damages: amount Promisee expected to benefit from performance
Make Promisee indifferent between performance and breach (i.e. as if the contract had been performed)

Reliance damages: compensate Promisee for cost of any reliance investments made, but not for additional surplus she expected to gain
Return Promisee to level of well-being before she signed the contract

Opportunity cost damages: give Promisee benefit she would have gotten from her next-best option
Make Promisee indifferent between breach of signed contract and performance of next best contract
In highly competitive markets, P≈P′, so expectation damages are nearly the same

You agree to sell me ticket to football game for $50
Expectation damages: you owe me value of game minus $50 (D=V−P)

You agree to sell me ticket to football game for $50
Reliance damages: cost of whatever pre-game investments I made (and nothing more), relying on your ticket for entry

Suppose lots of people were offering tickets on Craigslist for $60
Opportunity cost damages: $D=$90$, value lost from my next best option

| Contract Signed | ≥ | Best Alternative | ≥ | Do Nothing |
|---|---|---|---|---|
| Breach + Expectation damages | ≥ | Breach + opportunity cost damages | ≥ | Breach + reliance damages |
| $100 | ≥ | $90 | ≥ | $15 |
In general, expectation damages ≥ opportunity cost damanges ≥ reliance damages
If I am rational, will sign a contract at least as good as next best alternative, and doing nothing is an alternative (usually least valuable)
In this example, a pretty thick market for tickets
Much more difficult when goods are unique, very thin markets

Hawkins v. McGee, 84 N.H. 114, 146 A. 641 (N.H. 1929)
Hawkins’ hand was scarred from an electrical accident as a child
Dr. McGee approached Hawkins and guaranteed an operation that would result in a “one hundred percent good hand”
Hawkins sued for breach of contract
What is the appropriate amount of damages?


Other types of court-ordered remedies
Types of damages (not interesting but worth knowing)

Specific performance: court mandates Promisor to honor promise
Like injunctive relief in property law

Can specific performance be efficient?
We’ve generally seen that expectation damages will always result in efficient breach
However, there is a case that demonstrates this can sometimes go wrong

Peevyhouse v Garland Coal and Mining Co, 382 P.2d 109 (Okla. 1962)
Garland contracted to strip-mine coal on Peevyhouses’ farm
Contract specified Garland would restore property to original condition
Peevyhouses sued for breach of contract

Peevyhouse v Garland Coal and Mining Co, 382 P.2d 109 (Okla. 1962)
Full restoration estimated to cost $29,000
Both parties agreed everything else in the contract was successfully performed
Garland introduced evidence that despite the $29,000 cost to restore, the “diminution of value” of farm from mining was only $300
Original jury awarded $5,000 in damages to Peevyhouse
OK Supreme Court reduced damages to $300

Peevyhouse v Garland Coal and Mining Co, 382 P.2d 109 (Okla. 1962)
At first glance, seems like perfect example of efficient breach


“We therefore hold that where, in a coal mining lease, lessee agrees to perform certain remedial work on the premises concerned at the end of the lease period, and thereafter the contract is fully performed by both parties except that the remedial work is not done, the measure of damages in an action by lessor against lessee for damages for breach of contact is ordinarily the reasonable cost of performance of the work; however, where the contract provision breached was merely incidental to the main purpose in view, and where the economic benefit which would result to lessor by full performance of the work is grossly disproportionate to the cost of performance, the damages which lessor may recover are limited to the diminution in value resulting to the premises because of the non-performance.
“Under the most liberal view of the evidence herein, the diminution in value resulting to the premises because of non-performance of the remedial work was $300.00… It thus appears that the judgment was clearly excessive, and that the amount for which judgment should have been rendered is definitely and satisfactorily shown by the record.”
But the dissent argued the coal company was well aware of what they were getting into when they signed the contract
Most mining contracts at the time contained a standard per-acre diminution payment to cover damage (instead of working to achieve full restoration)
Dissent argued Peevyhouses therefore entitled to specific performance of the contract, the $29,000 worth of restoration
Expectation damages meant to make promisee as well off as if contract had been performed


“Defendant admitted in the trial of the action, that plaintiffs insisted the [remedial work provisions] be included in the contract and that they would not agree to the coal mining lease unless [those] provisions were included.
“The cost for performing the contract in question could have been reasonably approximated when the contract was negotiated and executed, and there are no conditions now existing which could not have been reasonably anticipated by the parties. Therefore, defendant had knowledge, when it prevailed upon the plaintiffs to execute the lease, that the cost of performance might be disproportionate to the value or benefits received by plaintiff for the performance...
“[D]efendant has made no attempt to even substantially perform. The contract in question is not immoral, is not tainted with fraud, and was not entered into through mistake or accident and is not contrary to public policy. It is clear and unambiguous and the parties understood the terms thereof...The defendant could have performed the contract if it desired. It has accepted and reaped the benefits of its contract...Therefore, in my opinion, the plaintiffs were entitled to specific performance of the contract and since defendant has failed to perform, the proper measure of damages should be the cost of performance.”
Appears the ruling attempted to turn an efficient default rule (expectation damages) into a mandatory rule, which would be enforced even when it was not what the parties intended in their contract
Think about it in terms of penalty defaults (Ayres and Gertner): contract promised restoration work, but did not specify the remedy if it was performed



For some reason, courts often hesitant to enforce remedy terms in contracts
Courts often refuse to enforce penalty damages: damages greater than actual harm that occurred (i.e. higher than expectation damages)

Effects of different remedies on:
Once all the decisions are made, and decision is in front of a jury, remedy is purely a question of redistribution
So to think about effect of chosen remedy on efficiency, think of the incentives created by the rule for similar situations


Under expectation damages
| Low Costs (Perform) | High Costs (Perform) | High Costs (Breach) | |
|---|---|---|---|
| You | V-P = $150,000 | V-P = $150,000 | D = $150,000 |
| Me | P-C = $50,000 | P-C' = -$650,000 | -D = -$150,000 |
| Joint | V-C = $200,000 | V-C' = $-500,000 | $0 |
Under specific performance
| Low Costs (Perform) | High Costs (Perform) | High Costs (Renegotiate) | |
|---|---|---|---|
| You | V-P = $150,000 | V-P = $150,000 | 150,000+(0.5*500,000) = $400,000 |
| Me | P-C = $50,000 | P-C' = -$650,000 | -650,000+(0.5*500,000) = -$400,000 |
| Joint | V-C = $200,000 | V-C' = $-500,000 | $0 |
So long as transaction costs are low, either remedy leads to same (efficient) outcome (when C>V)
But if transaction costs (of renegotiating) are high:

We haven’t talked much about efficient signing
With contract protected by specific performance, we saw:

Even expectation damages face this problem!
So expectation damages might create efficient breach, but might lead to inefficient signing

Suggests that, even if expectation damages are a sensible default rule, still efficient for parties to specify their own different damage rule in contract
Expectation damages are often efficient, but not always, so no reason to make them mandatory

Recall the agency or trust game
Principal decides to invest money ($100) with Agent
Agent can then keep or share the returns with Principal
As a one-shot interaction, we saw SPNE: (Don't, Keep)

Suppose they play this game again
If Agent kept in previous round, Principal can punish their defection by playing Don’t
This could lead to more cooperation, but all finite-games have a problem...

Suppose they both know there will be 10 rounds of this game
Using backwards induction, what will the outcome be in round 10?

Suppose they both know there will be 10 rounds of this game
Using backwards induction, what will the outcome be in round 10?
Given this, what will the players do in round 9?


The logical conclusion is that it is not rational to cooperate over time
“The Endgame problem”, Selten’s “chain store paradox”
The problem is the endgame is clearly defined

One-shot or finitely-repeated games are interesting, but rare
Some predictions for finitely-repeated games don’t hold up well in experiments or reality
We often play games or are in relationships that are indefinitely repeated (have no known end), we call them infinitely-repeated games
Suppose the players play this game indefinitely, with the following constant probabilities each round:
Suppose Principal plays a strategy known as the grim trigger strategy: start by playing Trust, and then if Agent plays Keep even just once, then play Don’t forever (infinite punishment)

With Principal playing grim trigger, consider Agent’s incentives each round:
If they Keep: get $200 this round, nothing ever again
If they Share: get $50 this round, $50 next round, $50 indefinitely...
With Principal playing grim trigger, consider Agent’s incentives each round:
If they Keep: get $200 this round, nothing ever again
If they Share: get $50 this round, $50 next round, $50 indefinitely...
Value of relationship:
50+50(0.90)+50(0.90)2+50(0.90)3+⋯=501−0.90=500
With Principal playing grim trigger, consider Agent’s incentives each round:
If they Keep: get $200 this round, nothing ever again
If they Share: get $50 this round, $50 next round, $50 indefinitely...
Value of relationship:
50+50(0.90)+50(0.90)2+50(0.90)3+⋯=501−0.90=500
Since 500>200, we can sustain cooperation!
Can determine what probability (or discount rate) is sufficient to sustain cooperation
Suppose you propose (marriage) to your sweetheart, they accept
Then you get cold feet
Should your fiancee be able to sue you for breach of contract?

In the old (and problematic) days, grooms had strong interest in preserving “purity” of bride
Traditional solution: if woman gets pregnant, man will marry her

Under common law, a spurned bride could sue for breach of promise to marry
Damages were value of reduction in future marital prospects

Damages were value of reduction in future marital prospects
...Until about the 1930s, when courts became unwilling to enforce this

A clever new solution: the engagement ring
Contrary to what DeBeers will tell you, the “tradition” of engagement rings is not ancient custom
