1. In combating diseases of the poor, Deaton identifies two causes. One cause is a private good provided by the market and the other cause is a public good provided by the government.
   1. What are these two goods and how do they combat the infectious diseases we find in poor countries?
   2. What is special about a public good? And what must be done to insure its optimal supply?
2. What evidence does Deaton provide to argue that inequality can start a process that benefits all?
