Note: With all this said about how wonderful markets are and how they coordinate millions of decisions through the price system, there is a role for government in the economy, and for central planning. NASA and the interstate highways system and sewers are all examples of excellent central planning. We'll study instances when markets fail later this semester, but as a general principle our first impulse is to let people interact freely in markets, then start regulating markets when they don't produce things like fairness or promote basic human rights or a sustainable environment.

1. On page 3 of the notes I linked this "Out There" video narrated by the New York Times science correspondent Dennis Overbye. Watch it.Why do you think space missions like this one are unlikely to be produced by decentralized markets, and instead usually require central planning? Do you think this was a good use of your tax dollars or not? This is a good example of a question not directly answered in the video or my notes or the textbook, but one which you have to think about. Don't just say yes or no, explain why you answered the way you did.(answer in a short paragraph)
