This perception is not accurate. Long-term interest rates have not been especially low. What has changed to produce high asset prices appears instead to be changes in popular economic models that people actually rely on when valuing assets. The public has mostly forgotten the concept of "real interest rate." Money illusion appears to be an important factor to consider. ER -
