This monograph is a revision of my Indiana University doctoral disserta-
tion which was completed in April, 1975. Thanks are, therefore, due to
the members of my doctoral committee: Saul Pleeter (Chairman), David J.
Behling, R. Jeffery Green, Richard L. Pfister, and Elmus Wicker for
their helpful comments on previous versions of the manuscript. In
addition, I am indebted to the Division of Research and to the Office of
Research and Advanced Studies at Indiana University for financial
support. As the reader will observe, the techniques developed in
Chapters 3 and 4 of this monograph are illustrated using input-output
data from West Virginia. These data were generously made available by
William H. Miernyk, Director of the Regional Research Institute at West
Virginia University. I also wish to acknowledge the Bureau of Business
and Eco- nomic Research at Arizona State University for providing two
research assistants, Kevin A. Nosbisch and Tom R. Rex, who aided in
processing the West Virginia data. A third research assistant, Phillip
M. Cano, also worked on this project as part of an independent study
program taken under my direction during the spring semester of 1975.
Finally, I must thank Mary Holguin and Margaret Shumway who expertly
typed the final copy of the manuscript. Despite the efforts of all the
individuals mentioned above, I assume responsibility for any errors
which may remain.
