developed and traded commercial and industrial property and public and private houses on a big
scale over a wide region. Edwards had done as well in the private as in the public sector. Both
were masters at the intricate trade and competition between the sectors, and at exploiting for
good public purposes the salutary influence which each sector can have on the other's efficiency
and social performance. For that central theme of this text readers can thank those two and Don
Dunstan, the head of government who made my opportunity to work with them.

I thank Mark Wootton of the Poola Foundation, Harold Wilkinson of the Oikoumene
Foundation and an anonymous donor for financial support. I thank my hosts for a year at the
University of York where the project was conceived. I am deeply grateful for ten research years
in the school of Economics at the University of Adelaide, with help of many kinds from John
Hatch, Jonathan Pincus, Richard Pomfret, Sue Richardson, Colin Rogers, Tom Sheridan and
other staff. I am deeply indebted to the goodwill and magical skills of Les Howard, exemplary
research librarian in the Barr Smith Library.

As always, I thank my family. Tolerant children put up with broken schooling and years away
from home. They gave me my first computer and made me use it. Whatever their private
thoughts about this project, they have generously encouraged it. Most of what the text says about
shared incomes and women's options is inspired by my good and clever sister Bid. And as the
preface to my first book said, for intellectual as well as domestic reasons, 'speaking of clever and
good, my wife Pat enabled this book to be written.' Now as then, I thank her most of all.
