Dear Economist & Undercover Economist (Tim Harford)
Tim Hartford writes the weekly advice column "Dear Economist" for the Financial Times. The questions come from many facets of modern life: quality coffee, eBay auctions, how to park cars, dating, and selecting the optimal number of children, to name a few. He uses neoclassical economics in his answers. His "Undercover Economist" column also focues on his observations, but it tends to be a bit less wide-ranging.
