Really interesting paper from [@profsufi](/user/profile/profsufi) [@AtifRMian](/user/profile/AtifRMian) and Ludwig Straub presented at the Jackson Hole symposium. Key finding: The drop in the natural rate of interest is more about rising income inequality than about demographics. Rich people save more. [https://t.co/OZuuJnYs0n](https://t.co/OZuuJnYs0n)
