Public goods theory is an economic concept that describes goods that are non-excludable and non-rivalrous, meaning that one person's consumption of the good does not reduce its availability to others, and people cannot be effectively excluded from using it. This theory emphasizes the role of the government or collective action in providing such goods, as the market may underprovide them due to the lack of incentive for private entities to invest in goods that benefit all.
