If Market Equilibrium is to Supply:Demand as Social Optimality is to ?

If Market Equilibrium is to Supply:Demand as Social Optimality is to Social Welfare, we can understand this by looking at how each concept relates to balance and efficiency. Market Equilibrium occurs when the amount of goods supplied matches the amount of goods demanded, meaning there is no surplus or shortage. Similarly, Social Optimality refers to a situation where resources are allocated in a way that maximizes overall happiness or welfare in society, not just for individuals or businesses. For example, if a city builds a park, it benefits the community by providing a space for recreation, which enhances social welfare. So, just as market equilibrium balances supply and demand, social optimality aims to balance individual needs with the greater good of society.
