This book is a collection of essays in honor of John C. Harsanyi. Originally, we hoped that it would be ready in the year of his 70th birthday, but we did not quite succeed. It sometimes takes longer than anticipated to do things as well as one wants. I think that John Harsanyi will understand this. It is my desire to express our thanks to all those who helped to make the book possible, especially to the publishing house, the Springer Verlag. I am grateful to Hildegard Grober who assisted us in the organizational tasks connected to our editorial effort. I am deeply indebted to Horace W. Brock. His active support was extremely valuable. The results of my editorial efforts should partly be attributed to him. Reinhard Selten Table of Contents Introduction 1 I.
