Acknowledgements and invitation
In writing this book I have been supported by many, in particular students
and colleagues.
My students at Erasmus University, Rotterdam have made many critical
comments on earlier versions of the text and the present book owes much
to them openly speaking their minds.
Many colleagues have helped me in making suggestions for conceiving
or adapting (specific parts) of the book. I mention in particular Sebastiaan
Princen (now with Utrecht University) and Max van der Sleen (of NEI/
ECORYS) who have critically reviewed the whole draft text. Their suggestions
helped to improve the internal consistency and to clarify the arguments.
Very valuable has been the secretarial support of Ineke van der Stap,
who prepared the manuscript for publication.
I thank them all for their help. Of course, I am the sole to blame for any
remaining errors and shortcomings.
I invite the reader to let me have the benefit of their criticisms. Please
send me an email at the address indicated. I will be happy to discuss with
you any proposals for improvement. Readers of a potential second edition
would benefit from your help.
