I have very little time today to write, first a very long flight and then preparation for a major release tomorrow of our latest Employment Vulnerability Index (EVI), which measures the risk of localised communities in Australia of unemployment as the economy slows. We have a very neat mapping tool and I will write about that tomorrow once the press launch occurs (first thing). But I am also working on various other papers and, as usual, have become immersed in the Phillips curve. I remember when I first started by PhD at the University of Manchester in the early 1980s, my then supervisor said to me on the first day that once I started modelling inflation and unemployment (the Phillips curve) I would never stop. Among other truths he uttered during my time in that dank part of the world that statement was spot on. Every now and then I return to the topic and update, revise, re-create and (sometimes) even innovate. So today’s blog is just a collection of snippets of the more accessible things I have been working on over the last few days. It starts with a graph that appeared in the IMF’s World Economic Outlook in April 2013. Then follow the graphs. Conclusion: The NAIRU as estimated is a very dangerous concept for the well-being of ordinary people.
