1.3.3 and 1.3.4 Public goods and info gaps Flashcards
What are public goods
-Have 2 characteristics, non-exculdability and non-rivalry
-Due to market failure many public goods are provided by the government but not all goods provided by the gov are public
What is non-excludability
-once a good is provided its impossible to exclude anyone from the benefits
-this makes it impossible for private firms to produce public goods for profit
-e.g national defence
What is non-rivalry
-one persons consumption doesn’t reduce the amount available for others
-e.g street lights
What are private goods
-most goods are excludable and rivalrous
-gives the ability to assert property rights
-the process of consumer sovereignty is only possible for private goods
-e.g food, clothes
What is the free rider problem
- a free rider will refuse to pay in the hope others will and they will still receive the benefits of the public good
-so the market mechanism is unable to provide public goods
What is perfect and symmetric info
-consumers and producers know everything there is to know about products and have the same level of knowledge
What is info failure
-In reality consumers and producers are not fully aware of costs and benefits, this leads to decisions based on incomplete or incorrect info, this leads to incorrectly positioned MPC and MPB
What could info failure be caused by
-Myopia, complex info, persuasive advertising, inability to consume/resist
What are some examples of info failure
-smoking, sunbeds, obesity
Difference between imperfect info and asymmetric info
imperfect- lacking crucial info to make a rational decision
asymmetric- one party has more info than the other, leading to imperfect decisions, leading to misalloction of resources
What is a moral hazard
-when the party with superior info alters behaviour to benefit them whilst imposing costs on the other party
-e.g insurance
How do the government intervene with info gaps
-regulation- legal bans and restrictions
-advice and guidance- persuasion, warnings
-provision of merit goods like healthcare
