What might the Soviet Union learn from the OECD countries in economics and politics ? An article from 1991 with some comments from 2005

When cleaning up my archives I came across a short article of April 1991 co-authored with Jan Tinbergen, on what the Soviet Union might learn from OECD countries in economics and politics.

Reading the article again in 2005 shows that some arguments still have value. In 2005, an advice, purely my own now, would be that Russia and the other republics of the former Soviet Union apply for membership of the European Union.
