If a contract is a (legally enforceable) promise...
...what should happen when the promise is broken?
Examples:
Promisee: brewery (buyer)
V: value of performance to promisee
Lots of things could happen in between:
A contract is a promise
Breach of contract is when promisor fails to keep a promise
So what should happen when a contract is breached?
Buyer Payoff | V−P (Buyer Surplus) |
Seller Payoff | P−C (Seller Surplus) |
Joint Payoff | V−C (Gains from Trade) |
Net gains from the contract performed
Buyer Payoff | V−P (Buyer Surplus) |
Seller Payoff | P−C (Seller Surplus) |
Joint Payoff | V−C (Gains from Trade) |
Net gains from the contract performed
Buyer Payoff | V−P (Buyer Surplus) |
Seller Payoff | P−C (Seller Surplus) |
Joint Payoff | V−C (Gains from Trade) |
Net gains from the contract performed
Suppose the cost of delivery C is uncertain when the contract is made
Once the actual C is realized, promisor (ice company) must decide to perform or breach contract
Condition for efficient performance: C<V
Condition for efficient breach: C>V
We know it's efficient to breach when C>V, but what will promisor actually do?
Promisor's cost to perform < promisor's liability from breach ⟹ Promisor will perform
Promisor's cost to perform > promisor's liability from breach ⟹ Promisor will breach
D: damages court awards to Promisee (paid by Promisor)
Promisor will perform: −D>P−C
Promisor will breach: −D<P−C
D: damages court awards to Promisee (paid by Promisor)
Promisor will perform: −D>P−C
Promisor will breach: −D<P−C
Can we design the law to only get efficient breach of contract?
D=V−P
Buyer Payoff | V−P (Buyer Surplus) |
Seller Payoff | P−C (Seller Surplus) |
Joint Payoff | V−C (Gains from Trade) |
Net gains from the contract performed
If Promisor breaches contract, imposes a negative externality on Promisee
If Promisor has to pay V−P in damages for breach, then they internalize the externality
Suppose the two companies agree on a price P and the ice company expects E[C]<P
Then both parties can expect to benefit from performance: V>P>E[C]
Suppose that in preparation for sale, the brewery invests R in producing a certain amount of beer, prior to the ice actually being delivered
This is a reliance investment, which depends on the performance of the contract
Another goal of contract law is to attain optimal level of reliance
V depends on the value of R
But must choose R before contract is performed/breached (ice delivered or not) and is a sunk cost (beer will spoil if ice not delivered)
D: damages the court awards in the event of breach (promisor pays promisee)
What value of D is efficient, i.e. induces promisor to breach only when it is efficient to do so?
Payoffs | Performance | Breach |
---|---|---|
Buyer's Payoff | V−P | D |
Seller's Payoff | P−C | −D |
Joint Payoff | V−C | 0 |
Payoffs | Performance | Breach |
---|---|---|
Buyer's Payoff | V−R−P | D−R |
Seller's Payoff | P−C | −D |
Joint Payoff | V−R−C | −R |
Payoffs | Performance | Breach |
---|---|---|
Buyer's Payoff | V−R−P | D−R |
Seller's Payoff | P−C | −D |
Joint Payoff | V−R−C | −R |
Payoffs | Performance | Breach |
---|---|---|
Buyer's Payoff | V−R−P | D−R |
Seller's Payoff | P−C | −D |
Joint Payoff | V−R−C | −R |
Recall condition for efficient breach: C>V
Note since R is a sunk cost, doesn't affect this condition!
Payoffs | Performance | Breach |
---|---|---|
Buyer's Payoff | V−R−P | D−R |
Seller's Payoff | P−C | −D |
Joint Payoff | V−R−C | −R |
Now consider what Seller will actually choose to do (once it knows C):
Seller will breach when C>P+D
Payoffs | Performance | Breach |
---|---|---|
Buyer's Payoff | V−R−P | D−R |
Seller's Payoff | P−C | −D |
Joint Payoff | V−R−C | −R |
We know what damages induce efficient breach (D=V−P), but what damages do courts actually set in breach cases?
Expectation damages: amount to make the promisor as well off as if the contract had been performed
Payoffs | Performance | Breach |
---|---|---|
Buyer's Payoff | V−R−P | D−R |
Seller's Payoff | P−C | −D |
Joint Payoff | V−R−C | −R |
Payoffs | Performance | Breach |
---|---|---|
Buyer's Payoff | V−R−P | D−R |
Seller's Payoff | P−C | −D |
Joint Payoff | V−R−C | −R |
Under reliance damages (D=R), what are seller's incentives to breach?
Recall seller will want to breach when C>P+D
Seller will want to breach when C>P+R
Payoffs | Performance | Breach |
---|---|---|
Buyer's Payoff | V−R−P | D−R |
Seller's Payoff | P−C | −D |
Joint Payoff | V−R−C | −R |
Finally, consider a rule of no damages (D=0)
Promisor will want to breach whenever C>P
Ranges of production costs over which breach occurs under the various damage measures
Party | Payoff | |
---|---|---|
You | V-P = | $150,000 |
Me | P-C = | $50,000 |
Joint | V-C = | $200,000 |
Suppose my costs rise to $400,000
If contract is performed:
Party | Payoff | |
---|---|---|
You | V-P = | $150,000 |
Me | P-C' = | -$50,000 |
Joint | V-C' = | $100,000 |
Suppose my costs rise to $400,000
Under expectation damages: I would owe you $150,000
Party | Payoff | |
---|---|---|
You | V-P = | $150,000 |
Me | P-C' = | -$50,000 |
Joint | V-C' = | $100,000 |
Suppose my costs rise to $600,000
If contract is performed:
Party | Payoff | |
---|---|---|
You | V-P = | $150,000 |
Me | P-C'' = | -$250,000 |
Joint | V-C'' = | -$100,000 |
Suppose my costs rise to $600,000
Under expectation damages: I would owe you $150,000
Party | Payoff | |
---|---|---|
You | D = | $150,000 |
Me | -D = | -$150,000 |
Joint | D-D = | $0 |
But this affects your incentives about how much to rely on my performance; your payoffs if:
So if expectation damages include the full added benefit, promisee will over-rely!
So if expectation damages include the full added benefit, promisee will over-rely!
Creates a moral hazard problem
If damages include full added benefit from reliance, promisee will invest more than the efficient amount in reliance
But if damages exclude the added benefit, then promisor will breach more often than is efficient, and underinvest in performance
Cooter & Ulen: include only efficient reliance
Actual courts: include only forseeable reliance
Hadley v. Baxendale (1854) EWHC J70
Hadley owned a flour mill, crankshaft broke
Hired Baxendale to transport broken shaft for repair
Hadley sued Baxendale for week of lost profits
Hadley v. Baxendale (1854) EWHC J70
Defendant conceded negligence in delaying the delivery, but claimed the requested damages were too high, since the need for the mill to close was only a “remote” possibility
“The shipper assumed that Hadley, like most millers, kept a spare shaft...Hadley did not inform him of the special urgency in getting the shaft repaired.”
“Where two parties have made a contract which one of them has broken, the damages which the other party ought to recieve in respect of such breach of contract should be such as may fairly and reasonably be considered either arising naturally, i.e., according to the usual course of things, from such breach of contract itself, or such as may reasonably be supposed to have been in the conemplation of both parties, at the time they made the contract, as the probable results of the breach of it.”
Hadley v. Baxendale (1854) EWHC J70
In other words, expectation damages for breach will be limited to a reasonable level
Found the lost profits were not reasonably forseeable, thus not entitled to damages on those
“But it is obvious that, in the great multitude of cases of millers sending off broken shafts to third persons by a carrier under ordinary circumstances, [these particular] consequences would not, in all probability, have occurred, and these special circumstances were here never communicated by the plaintiffs to the defendants. It follows, therefore, that the loss of profits here cannot reasonably be considered such a consequence of the breach of contract as could have been fairly and reasonably contemplated by both the parties when they made this contract”
Why didn’t Hadley and Baxendale just specify in the original contract what happens in the event of a delay?
What rules should apply in circumstances that aren’t specified in a contract?
In economics & contract theory, a complete contract specifies all actions or transfers that parties must take under every possible contingency
In the real world of uncertainty, complete contracts are impossible
Instead people maximize their expected utility given limited information at the time (“bounded rationality”)
Agreements are always incomplete contracts, actions for many (unforeseen) contingencies are unspecified
Even for specified actions and contingences, outcomes are indeterminate due to enforcement costs
Gives rise to post-contractual opportunism (shirking, fraud, renegotiation, hold-up, etc)
Research in industrial organization about how firms solve these problems of transaction costs
Note this line of research comes directly out of Coase (1937): firms are a solution to high transaction cost situations
Oliver Hart
1948-
Economics Nobel 2016
"We define the firm as being composed of the assets (e.g., machines, inventories) that it owns. We present a theory of costly contracts that emphasizes that contractual rights can be of two types: specific rights and residual rights. When it is too costly for one party to specify a long list of the particular rights it desires over another party's assets, it may be optimal for that party to purchase all the rights except those specifically mentioned in the contract. Ownership is the purchase of these residual rights of control." (p.692).

Gaps in contracts: risks or circumstances not explicitly addressed
Default rules: the rules courts apply to fill in gaps
Cooter & Ulen: use the rule parties would have wanted if they had chosen to bargain over this issue
Normative Coase Theorem implies law should minimize transaction costs
Don’t want ambiguity in law, so default rule can’t be different case by case
Majoritarian default rule: the terms that most parties would agree to
Court: figure out efficient allocation of risks (what parties would have done)
Suppose a family contracts with construction company to build house
Construction company knows: 50% chance of costs increasing by $2,000
The company can hedge this risk (buy supplies in advance and keep in storage, etc.) at a cost of $400
Family doesn’t know anything about this possibility, and has no way to mitigate the risk
The company chooses not to hedge against the risk
It turns out, costs indeed went up $2,000
How should the court address this?
Construction company here is the efficient bearer of the risk
An efficient contract would have allocated the risk to the company
Should court adjust prices to compensate?
Court might rule the spike in costs was reasonably forseeable
It might not have been reasonably forseeable
Sometimes better to make default rules something the parties would not have wanted, a penalty default
Ayres & Gertner argue sometimes gaps are result not of transaction costs, but strategic reasons
Ayres, Ian and Robert Gertner, 1989, “Filling Gaps in Incomplete Contracts: An Economic Theory of Default Rules,” Yale Law Journal 99
Baxendale (shipper) is only one who can affect when crankshaft is delivered — efficient bearer of risk
If default rule held Baxendale liable, Hadley has no need to tell him the shipment is urgent!
So Hadley might conceal this information, which is inefficient
Ayres and Gernet: Hadley vs. Baxendale ruling was correct, not because it was efficient, but because it was inefficient!
Ruling created incentive for disclosing information and forcing parties to prevent inefficient gaps in contracts
To see their logic, suppose
If shipper is liable for actual damages
If shipper is liable for forseeable damages (Hadley rule)
Look at why parties left a gap in a contract:
If due to high transaction costs → use efficient rule
If due to strategic reasons → penalty default may be more efficient
