The dreaded NAIRU is still about! I was thinking – rather optimistically – that it would just disappear from whence it came! But sorry to disappoint. Some economists just won’t learn. Yesterday the ABS released the latest data from the Australia Treasury Model (TRYM) database. You can get it here. Among other things of great interest that you can find in that database, is the Treasury TRYM model’s estimates of the so-called NAIRU. Sounds scary. Well, it stands for the the Non-Accelerating Inflation Rate of Unemployment and has a central place in neo-liberal mythology. The NAIRU is an important component of the TRYM model and influences the way it produces economic outcomes and policy simulations. So how much reliance should we place on this important component of the policy making process. Answer: not much!. My conclusion: any model that relies on a NAIRU is a crock!
