For many public services, national parks for example, we normally think of separate persons enjoying similar physical facilities. An example of a pure public good is street lighting: one individuals enjoyment of the lighted street does not in any way detract from that same enjoyment of others. government should provide certain goods, independently of whether or At this point, we are not directly concerned with the values, positive or negative, that direct or indirect beneficiaries may place on such service flows. game theory, section on repeated games and coordination). Coase, Ronald H., 1974, The Lighthouse in Economics. Note that through this device of considering each persons consumption as a separate public service, we have converted the model into one where joint supply necessarily applies. A lighthouse In this model, there need be no external economies from production in the orthodox sense, hence, no jointness efficiencies. boat and a desire to travel to the coast where the lighthouse is There need not exist such a one-for-one correspondence among separate consumption components in all public goods, even in those which can be classified as purely public in some more general sense. Individuals who are not party to the transaction can In that formulation, we could not have possibly been defining equal availability in terms of similar quantities of homogeneous-quality consumption units.
