Some years ago, when Principal and Professor of Economics at the infant Univer sity of Buckingham, Britain's only independent university, I was intrigued to receive an application, supported by strong recommendations from a Signora Ilde Rizzo, who wished to take some courses in public finance. As she was already an of Catania, noted for its expertise in the economics of Assistant at the University public finance, my colleagues and I brushed aside her modest request to attend undergraduate courses and enrolled her in our new graduate course. We also hoped that she might, in time, be able to gain experience in teaching and writing in English. Dr. Rizzo exceeded our highest expectations. She presented the first D. Phil thesis ever at Buckingham and defended it with consummate success. This work is a revised and extended version of her thesis, and it is a pleasure to congratu late Dr. Rizzo on its appearance, and also her publisher for recognizing its qUality. It will come as no surprise to the reader that Dr. Rizzo has already published extensively in Italian and also in English, but this is her first book in the latter language. I am glad to think that Dr. Rizzo's thesis arose out of our mutual interest in the question as to whether debt financing offered governments a major opportunity for maintaining the growth of public spending.
