Hi there,
I'm working on a paper concerning the link between international
parity and granger causality. In order to built PPP the WPI
series from 1975M03 on from USA, UK, Germany, Japan and Canada
would be of great help for me. After several days of search I
had to draw the conclusion that the series from IMF's
International Financial Statistics are the only chance to get
comparable information. However, I have not access to them. Does
someone can help me out?
