This is a course for those who are interested in the challenge posed by massive and persistent world poverty, and are hopeful that economists might have something useful to say about this challenge. The questions we will take up include: Is extreme poverty a thing of the past? What is economic life like when living under a dollar per day? Are the poor always hungry? How do we make schools work for poor citizens? How do we deal with the disease burden? Is invaluable microfinance or overrated? Without property rights, is life destined to be "nasty, brutish and short"? Should we leave economic development to the market? Should we leave economic development to non-governmental organizations (NGOs)? Does foreign aid help or hinder? Where is the best place to intervene? And many others.
