How does the concept of economic efficiency influence market equilibrium when limited resources are allocated to public goods?

Economic efficiency is about using resources in a way that maximizes benefits to society. When we talk about public goods, like parks or streetlights, these are things that everyone can use without reducing their availability to others. Limited resources mean that we can't provide everything everyone wants, so we must decide how to allocate them wisely. For example, if a city has a fixed budget for public parks, it needs to consider how many parks to build to benefit the most people, ensuring that the resources spent create the highest overall satisfaction. This balance helps achieve market equilibrium, where the supply of public goods meets the community's needs without wasting valuable resources.
