The editor gratefully acknowledges the stimulating, efficient and friendly working environment furnished by UNU/WIDER. Helpful comments were received from Moshe Syrquin and two anonymous reviewers of the manuscript, but they bear no responsibility for any shortcomings. The UNU/WIDER support staff provide an outstanding example of 'enabling social capital'. Special thanks are due to Anne Ruohonen, the exceptionally able and eternally cheerful secretary to the project.
