参加西北大学外教博弈论（高级微观领域）课程时，跟外教要的书，教授没有透露书名，但给了整本电子书，内容很精彩的。
preface：
     This book presents some of the main ideas of game theory. It is designed to serve as a textbook for a one-semester graduate course consisting of about 28 meetings each of 90 minutes.
     The topics that we cover are those that we personally would include in such a one-semester course. We do not pretend to provide a complete reference book on game theory and do not necessarily regard the topics that we exclude as unimportant. Our selection inevitably reects our own preferences and interests. (Were we to start writing the book now we would probably add two chapters, one on experimental game theory and one on learning and evolution.)
      We emphasize the foundations of the theory and the interpretation of the main concepts. Our style is to give precise denitions and full proofs of results, sacricing generality and limiting the scope of the material when necessary to most easily achieve these goals.
     We have made a serious eort to give credit for all the concepts, results, examples, and exercises (see the \Notes" at the end of each  chapter). We regret any errors and encourage you to draw our attention  to them.

Structure of the Book：
   The book consists of four parts; in each part we study a group of related  models. The chart on the next page summarizes the interactions among the chapters. A basic course could consist of Chapters 2, 3, 6, 11, 12, and 13.
