Bubbles, Bubbles Everywhere

``This week we'll think about bubbles. Specifically, we'll have a look at part of the chapter on bubbles from my latest book, Code Red, which we launched last week. At the end of the letter, for your amusement, is a link to a short video of what you might hear if Jack Nicholson were playing the part of Ben Bernanke (or Janet Yellen?) on the witness stand, defending the extreme measures of central banks. A bit of a spoof, in good fun, but there is just enough there to make you wonder what if ... and then smile. Economics can be so much fun if we let it.''
