Market Failure
public goods
Merit and demerit goods
Externalities
Information asymmetries and gaps
Absence of private property rights
Income inequality
Volatile prices
1) public goods
Non-excludable: no one is prevented from consuming the good
Non-rival: the benefit people get from the good doesn’t diminish if more people consume the good
E.g. army/street light
under provided due to free rider problem (people who benefits from the good without paying for it)
private sector don’t make profit
Difficult to measure the value consumers get from public goods, hard to put a price
2) merit goods
E.g. education & healthcare
Demerit goods
E.g. cigarettes & alcohol
