Private Property Rights
“Negative Externality”:
When you produce or consume a
commodity or service within your
private property rights that imposes a
cost on a third party not directly
involved in the market transaction.
Private Property Rights
The cost imposed on the third party is
very difficult (expensive) for the third
party to recover
AKA a “Spillover Cost”
Private Property Rights
Laws are often enacted by legislative
bodies that constrain private property
rights in order to rectify negative
externalities, or at least reduce the
cost to third parties in recovering
damages
Negative Externalities
Some Examples:
-Seat Belt Crack
Down in Tehran.
-Iran Law for
Motorcyclists.
Negative Externalities
Possible Solutions:
–
–
Pass Laws
Post Bond to assure financial
responsibility
Positive Externalities
When you produce or consume a
commodity or service within your
private property rights that bestows a
benefit on a third party not directly
involved in the market transaction.
Positive Externalities
The benefit bestowed on the third party
is very difficult (expensive) for the
third party to recover
AKA a “Spillover benefit”
