Statement 1 is correct. Public goods are defined by two main characteristics: non-rivalry (consumption by one person does not reduce availability for others) and non-excludability (it is difficult or impossible to prevent individuals who have not paid from consuming the good). Examples include national defense or street lighting. Statement 2 is incorrect. Markets typically fail to provide the optimal amount of a good when externalities are present. Negative externalities (like pollution) lead the market to produce too much of a good from a societal perspective, while positive externalities (like vaccination) lead the market to produce too little. The market price does not reflect the full social costs or benefits in the presence of externalities, leading to inefficiency.
Public goods and externalities are classic examples of market failures, where the unfettered market mechanism does not lead to a socially optimal outcome.
Government intervention, such as direct provision (for public goods) or Pigouvian taxes/subsidies, regulations, or tradable permits (for externalities), is often required to address these market failures and move towards a more efficient allocation of resources.
