Hi, indeed it is true that our library has access to many databases. Meanwhile I found one that contains IMF information too. I used the 5 day trial and in terms of the cpi series, they are the same which oecd provides. WPI or Germany is unfortunately "only" unified and hence much shorter than in the original paper I'm working on. Nevertheless it's good that a use the money market rates from IFS since they are really different from the oecd data and that did have an impact on the vecms results. Gather data from different sources - what about using indices that have a different different base in one regression? Is that a severe problem? Thanks for the support and ideas!

Most academic libraries and/or computing services have access to IMF, EU and other data for use by students and staff, often through data services provided by consortia of universities. There is one in the UK and I would expect that there is something similar in Germany. If the Free University doesn't have such access, then you should lobby for it. Academic subscriptions to international datasets are usually very cheap. 2. There is no particular advantage to using data from the IFS. It is just a compilation of data from national sources. Since you are dealing with a few OECD countries, you can extract data from the OECD's online databank without charge or, indeed, from the relevant national sources. I am not sure about Japan but it is certainly possible to get what you want for the other countries.

To: Gretl list <gretl-users(a)lists.wfu.edu&gt; Message-ID: <4D19AD23.1080007(a)zedat.fu-berlin.de&gt; Content-Type: text/plain; charset="iso-8859-15" 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?
