Problem: Is each a good example of a public good, externality, or neither? If an externality, is it positive or negative? Explain.
Note: public good examples are often not that clear in practice. Your answers may well differ from mine. Just think these through carefully and rigorously.
1. National Public Radio, public television, or the BBC in Britain.
2. Herds of wild horses that roam Assateague Island in Maryland & Virginia.
3. An ultra-modern building built on a city block that previously had only architecturally coherent Victorian structures.
4. Fishing for whales in international waters.
