When I took econ in the mid to late 80s, the Phillips curve was still in the text books but in the lectures it was treated as a historical theory that had been overwhelmed by new evidence like luminiferous ether in physics or Lamarckian inheritance in biology. It looks like it is either coming back, or at least those who think they can profit (either monetarily or in power) from running the printing presses at ludicrous speed are digging it back up.
