Tim Harford – The Undercover Economist (2006)
Economics is in many ways just like engineering; it will tell you how things work and what is likely to happen if you change them. … Yet the fact that economics is a tool for objective analysis doesn’t mean that economists are always objective. … Billions of people could benefit from better economic policies. Millions are dying because of bad ones. Sometimes the logic of economics is so compelling that it’s impossible for economists not to take a stand.
