8 Foreword and Acknowledgements This book is the final product of a research project sponsored by the Corporate Counsel Center of the Northwestern University School of Law. The project was funded through a 1985 grant to the Center by American Information Technologies Corporation (Ameritech). The principal condition of the grant was that it be used to support research in regulatory matters. Within this broad purpose, the particular subject matter was determined by Professor Hillman, of the Law School, as principal researcher and Professor Braeutigam, of Northwestern's Department of Economics, as economic consultant. These authors appreciate the support provided by Ameritech's grant to the Center and the complete independence accorded to them in their work. They also wish to acknowledge the substantial contributions of Messrs. Erik F. Dyhrkopp and Steven M. Spaeth, as law student research assistants. A further condition of the grant was that the final results be presented at a Law School conference. This was held on November 18, Following the principal presentation by Professors Hillman and Braeutigam, responsive commentaries were made by two academic economists and two academic lawyers. The economists were Victor P. Goldberg, Thomas Macioce Professor of Law, Co-Director, Center for Legal and Economic Studies, Columbia University School of Law and Almarin Phillips, John C. Hower Professor of Public Policy and Professor of Law and Economics, University of Pennsylvania. The lawyers were Ian R. Macneil, John Henry ix

Hutchison Professor of Law, Southern Methodist University. The inherent complexities and tensions of price level regulation, whether for diversified or non-diversified public utilities, were underscored in these responses. The Afterword to the book contains a brief summary of some of the major points made by three of the commentators. Professor Macneil preferred not to have his views stated in summary form.
