Written by John LounsburyThis week we are repeating a video from last November that I consider one of the most important we have present on this website.. It addresses what Lars Syll has called a wonkish subject. Be that as it may, the concept is so important in financial and economic analysis, and so often abused, that it should be repeatedly studied until it is no longer wonkish, or until you become a wonk. If you pursue this recommendation you will have the tools to become a rich wonk, should you so chose.
