Property Law Legal framework for allocating resources

and distributing wealth Economic Goal: efficient resource allocation

Economic Theory of Property Bargaining theory (game theory) Public goods theory Externalities theory

Orbitcom, Inc., spent $125 million designing, launching, and maintaining a satellite for the transmission of business data between Europe and the US. The satellite is positioned in a geosynchronous orbit 25 miles above the Atlantic Ocean. Recently a natural resource-monitoring satellite belonging to the Windsong Corp. has strayed so close to Orbitcom’s satellite that the company’s transmissions have become unreliable. As a result, Orbitcom has lost customers and has sued Windsong for trespassing on Orbitcom’s right to its geosynchronous orbit.

Economics of Bargaining Peter owns a horse which he claims is worth $9,000 to

keep, and Mary covets the horse and decides she is willing to pay $11,000 for it. Mary has $15,000 inheritance income. Non-cooperative outcome: no trade Cooperative outcome: trade at mutually agreed price

Value of Cooperative Outcome = [10,000] + [11,000 + 5,000] = $26,000

Value of Non-cooperative Outcome = $9000 + $15,000 = $24,000

(threat values)

Reasonable sale price = $10,000

Cooperative Surplus = $2,000

A Theorem and a Corollary

Coase TheoremIf transactions costs are low enough, then private bargaining will result in an efficient use of resources, regardless of the legal assignment of property rights.

CorollaryWhen transactions costs are high enough to prevent bargaining, the efficient use of resources will depend on how property rights are assigned.

Lubricate or Allocate? Normative Coase Theorem

Structure the law so as to remove impediments to private agreements

Normative Hobbes Theorem Structure the law so as to minimize the harm

caused by failures in private agreements

Lawmaker tradeoff: IC = information cost of the court in

determining who values a right the most TC = transaction costs of private bargaining

Efficient courts would follow this rule: If IC < TC allocate legal right to the party

who values it the most If TC < IC strictly follow precedent

Lubricate or Allocate?

How are property rights protected? Remedies for violations:

Damages (legal) compensatory money payment “backward-looking”

Injunctions (equitable) an order to perform or refrain from an action “forward-looking”

Torts or contracts

Calabresi and Melamed (1972) If TC are low, then injunctions are efficient

For private bads If TC are high, then damages are efficient

For public bads

Suppose that an investment of $100,000 in research yields a pioneering invention that has no commercial value. A subsequent investment of $50,000 in development yields an improvement to the pioneering invention that has commercial value of $1 million. An efficient patent law would grant the patent to:

1 2 3 4 5

a) The pioneerb) The developerc) Equal rights to bothd) Neither of them

Why limit duration? Tracing costs exist

Why has duration increased? Copying costs have fallen

Simple to administer Encourages inefficient pre-emptive investments

Tied ownership: fugitive property is tied to something else that is easier to establish

Costly to administer Encourages efficient use of resource
