As former Prime Minister Margaret Thatcher once said, "Truth is too precious to become the slave of fashion." I dedicate this book to those students of mine who have an inquiring mind and the ability to question conventional thinking about public policy issues.

I dedicate this book to my father, W. R. Allen, now deceased, and my brother, Robert J. Allen, for their infinite patience and encouragement through the years. Part of this book belongs to Beverly Blair Cook, Cornelius Cotter, and James Gibson--all of whom taught me my trade yet remain blameless for what I did with the lessons. I would also like to thank John Albright, Manfred J. Enssle, and Thomas Knight, who, collectively, listened to the story of the project more times than anyone has a right to expect. Finally, this book is for W. B. Yeats, Dylan Thomas, and Lawrence Ferlinghetti--simply because you cannot read quantitative literature all the time and remain sane.

Dedicated to the memory of Weldon K. Hill--my grandfather, my mentor, my friend.
