INFORMATION TO USERS This manuscript has been reproduced from the microfilm master. UMI films the text directly from the original or copy submitted. Thus, some thesis and dissertation copies are in typewriter face, while others may be from any type of computer printer. The quality of this reproduction is dependent upon the quality of the copy submitted. Broken or indistinct print, colored or poor quality illustrations and photographs, print bleedthrough, substandard margins, and improper alignment can adversely affect reproduction. In the unlikely event that the author did not send UMI a complete manuscript and there are missing pages, these will be noted. Also, if unauthorized copyright material had to be removed, a note will indicate the deletion. Oversize materials (e.g., maps, drawings, charts) are reproduced by sectioning the original, beginning at the upper left-hand corner and continuing from left to right in equal sections with small overlaps. Each original is also photographed in one exposure and is included in reduced form at the back of the book. Photographs included in the original manuscript have been reproduced xerographically in this copy. Higher quality 6" x 9" black and white photographic prints are available for any photographs or illustrations appearing in this copy for an additional charge. Contact UMI directly to order.

Jayanti B.Sc./ Andhra University, India, 1971 M.Sc., Andhra University, India, 1973 August 1991 ACKNOWLEDGMENTS This dissertation benefitted from the help of many people. First, I would like to thank Geoffrey Booth, my chairman, for his constant encouragement and inspiration. His enthusiasm is contagious. Equally important is the contribution of Myron B. Slovin who provided valuable insights into the problem at hand. Chowdhury Mustafa was very helpful with every aspect of the GARCH model. I express my deep appreciation to them. I am also thankful to the other members of my committee: John Glascock, Bill Lane, Douglas McMillin, and Paul Hoffman for their valuable time. I acknowledge the help from William Staats, Kwei Tang, Upinder Dhillon, Erdal Gunay, John Hatem, Quang Do, Mimbo Kim, Venkat Chalasani, Joan Payne, Bessie Avera, and Kathy Bosworth. They lent a helping hand at various stages of the dissertation. I owe special thanks to my wife, Rama, who is a friend, philosopher, and guide to me. She was absolutely invaluable right from the conception of the idea of going for the Ph.D. through its successful completion. I am grateful to all my family members for their support and encouragement. Finally, the love and blessings of my parents guided me throughout. I dedicate this work to my parents.
