Weekend Links: Understanding Piketty, Falling Interest Rates, Secular Stagnation, etc

1. Brad Delong has a great post that provides an analytical framework for understanding the historical narrative in Piketty’s new book.
2. Barry Eichengreen has a nice piece on declining interest rates
3. Larry Summers gave a talk at INET (starts at 45 min and goes to 1:38 or so) with some especially interesting hypotheses about the changing structure of investment (from GE’s high capital investment model to Google’s abundance of cash) and reflections on the agriculture transition (around 1:21) and the associated difficulties with large shifts in the industrial composition of employment.
