Anyone who has done first year economics will know about shifts and movements. When I tutored the course I would make funny hand gestures trying to illustrate it, hand gestures that were mildly less weird then when I talk about price floors and ceilings.
Still, there has been a lot of banging on about the carry trade and mortgage rates, and I think some of it stems from a little confusion regarding shifts and movements. As an example I’ll work with this post from the Standard (ht BK Drinkwater).
Note: This is being added to the inflation debate, as a discussion of interest rate determination in a small open economy. Starting from the bottom, the combination of posts under that tag gives a fuller idea of what we are talking about with inflation targeting and our (narrow) view of monetary policy.
