Property Rights, Resource Taxonomy, and Externalities

Comprehensive practice flashcards covering property rights, the Coase Theorem, resource taxonomy (excludability and rivalry), the tragedy of the commons, public good pricing dilemmas, and the connection between non-excludability and externalities.

How are property rights defined?

Property rights are our way of deciding who gets to use what, when.

How do private property and exchange tend to allocate resources?

Private property (exclusive claims) and subsequent exchange tend to allocate resources to their highest-valued use through bargaining.

Why is the Coase Theorem often interpreted as diminishing the importance of property?

Because it states that if transaction costs are zero, the initial assignment of property rights does not matter for efficiency.

What was Ronald Coase's primary point regarding transaction costs and property rights?

Transaction costs are not zero in reality, meaning the initial assignment and structure of property rights do matter for efficiency.

What two characteristics do economists use to classify different types of resources?

1. Excludability: the ability to exclude non-payers.
2. Rivalry (in consumption): whether one person's consumption prevents other people from consuming the same good.

What is a private good, and what are examples of it?

A good that is both rival and excludable; examples include food, clothing, and cars.

What is a common pool resource (CPR), and what are examples of it?

A good that is rival in consumption but non-excludable; examples include fisheries, forestry, and roads.

What is a club good (or toll good), and what are examples of it?

A good that is excludable but non-rival in consumption; examples include movie theaters, pool clubs, toll roads, and satellite radio.

What is a public good, and what are examples of it?

A good that is both non-excludable and non-rival; examples include air, radio, and national defense.

Why do excludable goods generally present few efficiency concerns regarding the good itself?

Divergences between private and social costs usually stem from how consumption affects other resources (e.g., driving a car affecting clean air) rather than from the good itself.

What do pricing inefficiencies indicate for excludable goods?

If valuation exceeds cost yet the good is not purchased, it is priced too high; if congestion and tragedy occur in a club good, it is priced too low.

Why can inefficiencies in non-excludable goods not simply be resolved through price adjustments?

Because consumers cannot, by definition, be excluded or forced to pay the price.

What incentive arises from the inability to exclude non-payers?

An incentive to free ride, where individuals consume the good without paying while relying on the production, maintenance, and conservation efforts of others.

How does free riding manifest in common pool resources (CPRs)?

It creates congestion and overconsumption, as each individual has an incentive to consume before others do, resulting in the "tragedy of the commons."

What is the standard government solution to the tragedy of the commons in CPRs?

Regulating access and enforcing consumption quotas.

Why are public goods susceptible to underproduction rather than overconsumption?

They cannot be overconsumed because they are non-rival, but firms cannot collect sufficient revenue to justify production because non-payers cannot be excluded.

What is the standard solution to the underproduction of public goods?

Forcing payment through taxes and having the government produce the good.

What is the marginal cost of adding an additional consumer to an already produced public good?

$MC = 0$, because the good is non-rival in consumption.

What pricing dilemma exists for public goods when $MC = 0$?

The efficient price is zero ($P = 0$), but at zero price no producer will supply it; any positive price ($P > 0$) prevents mutually beneficial consumption where $P > MV > 0$.

What is an alternative market-oriented solution to address inefficiencies in public goods and CPRs?

Making the goods more excludable (through technology, violence, or organizational rules), turning CPRs into private goods and public goods into club goods.

How can the overconsumption of a common pool resource be reframed as an externality?

It is a negative externality because the cost of overconsumption is spread across society rather than being fully reflected in the good's price.

How can the underproduction of a public good be reframed as an externality?

It is the result of a very large positive externality, where the benefits generated for non-payers cannot be captured by the producer in revenue.

What is the "proper" price required to maximize surplus and incentivize efficient behavior?

The proper price occurs where $P = MV = MC$.

Under what condition does a negative externality persist due to improper pricing?

When the price is too low to reflect social costs: $SMC > MV = P \ge PMC$.

Under what condition does a positive externality persist due to improper pricing?

When the price or return to production is too low to capture social benefits: $SMV > PMV \ge P = MC$.
