[Gretl-users] WPI series - Has somebody access to IMF's International Financial Statistics?

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? Best Pindar
