Some companies pursue growth despite a recession –and there’s a theory behind that.

BusinessWeek this week highlights a number of companies that are pursuing growth despite the recession -- including Inditex (owner of clothing retailer Zara), Procter & Gamble, and small entrepreneurial businesses such as JustAnswer.  For more on the theory behind investing in a downturn, see the new version of  "The Risk of Not Investing in a Recession" by Pankaj Ghemawat. It's a classic MIT Sloan Management Review article that was updated in the Spring 2009 issue -- and also included in our  "Downturn Manifesto" special report.
