On a tour of North Korea, "silly white folks 'working with the people.' " North Korean Economy Watch
On today's Planet Money:
-- When you arrive as a tourist in North Korea -- yes, it's been done -- they don't tell you the news, says Curtis Melvin. They tell you the state of the economy. And yes, they do have one. Melvin knows because he tracks it on his blog, North Korean Economy Watch. His biggest boosts come from YouTube and Google Earth, which let him watch what passes for economic development.
-- The "efficient market" hypothesis holds that everyone trading stocks is generally trying to take in the same information about companies, and the result of all that thinking is the price of stock. The efficiency of the market makes it hard for any individual to beat the market over the long haul. So why would anyone pick stocks at all, or listen to a professional stock picker like CNBC's Jim Cramer? (Further fun: Video of Cramer rebutting an academic study of his performance.)
Bonus: Paycheck bounces, life falls apart and video of a North Korean market
