A
  • taxes
  • legislations
  • tradeable emission permits
18
Q

problems with tradeable emission permits (for negative production externalities)

A

  • creates non-consumption of the good (though the good might be necessary for producers)
  • high cost in setting and enforcing the legislation
20

A
  • difficult to set a value on the externality
  • difficult to identify which firms are responsible for what levels of production

21
Q

characteristics of common pool resources

A

Rivalrous and non-excludable.

This means that the consumption of the good reduces its availability for others but it is impossible to exclude others from using it (i.e. finite but priced at 0)

22
Q

how does unsustainable production of common pool resources create negative externalities?

A

The lack of price means that the rationing function does not occur, leading to overuse

23
Q

solutions to the tragedy of the commons

A
  • Carbon taxes
  • Tradeable emission permits
  • Subsidizing cleaner substitute gods
  • Legislation
  • Collective self-governance
24
Q

characteristics of public goods

A

non-rivalrous and non-excludable.

This means that the consumption of the good does not reduce its availability for others and it is impossible to exclude others from using it.

25
what is the free rider problem?
When people can enjoy a good without paying for it, it creates market failure as there is no incentive that incentivizes firms to produce the good.
26
Forms of government intervention in response to public goods
* free govt. provision * contracting out to the private sector
27
asymmetric information | definition + types
When buyers and sellers do not have equal access to information. Types: * Adverse selection: when one party (buyer or seller) has more information than the other party about the *quality* of the product being sold * Moral hazard: where one party takes a risk but does not bear all of the consequences of the risk
28
government responses to adverse selection
* regulation * provision of information * licensure
29
private responses to adverse selection
* screening: consumers seek more information by screening (researching) the product * signalling: the use of trusted measures of quality to signal the quality of the product (e.g. warratnies, brand names)
30
free good vs economic good
**Public good:** * Is not scarce * Has 0 opportunity cost **Economic good:** * Is scarce * Has an opportunity cost
31
responses to moral hazard
Solutions seek to realign the incentives: * insurance * deductibles (out-of-pocket)
