<P>Stokey和Lucas 的Recursive Methods in Economic Dynamics,学习高级宏观的一个很好的数学词典,这个是他的答案.下面是他的前言.</P>
<P>不好意思,发了才知道论坛已经有了,不过还是推荐这本书,就是有点难度.</P>
<P>Foreword</P>
<P>Over the years we have received many requests for an answer bookfor the exercises in Recursive Methods in Economic Dynamics. These requests have come not from inept teachers or lazy students, but from serious readers who have wanted to make sure their time was being well spent.</P>
<P>For a student trying to master the material in Recursive Methods,the exercises are critical, and some of them are quite hard. Thus it is useful for the reader to be reassured along the way that he or she is on the right track, and to have misconceptions corrected quickly when they occur. In addition, some of the problems need more specific guidelines or sharper formulations, and a few (not too many, we like to think) contain errors — ommands to prove assertions that, under the stated assumptions, are just not true.Consequently, when three of our best graduate students proposed to write a Solutions Manual, we were delighted. While we firmly believe in the value of working out problems for oneself, in learning by doing, it is clear that the present book will be an invaluable aid for students engaged in this enterprise.<br>The exercises in Recursive Methods are of two types, reflecting the organization of the book. Some chapters in the book are selfcontained expositions of theoretical tools that are essential to modern practitioners of dynamic stochastic economics. These “core”chapters contain dozens of problems that are basically mathematical: exercises to help a reader make sure that an abstract definition or theorem has been grasped, or to provide a proof (some of them quite important) that was omitted from the text. This Solutions Manual contains solutions for most of the exercises of this sort. In viii ix particular, proofs are provided for results that are fundamental in the subsequent development of the theory.<br>Other chapters of Recursive Methods contain applications of those theoretical tools, organized by the kind of mathematics they require.<br>The exercises in these chapters are quite different in character. Many of them guide the reader through classic papers drawn from various substantive areas of economics: growth, macroeconomics, monetary theory, labor, information economics, and so on. These papers, which appeared in leading journals over the last couple of decades, represented<br>the cutting edge, both technically and substantively. Turning a paper of this sort into an exercise meant providing enough structure to keep the reader on course, while leaving enough undone to challenge even the best students. The present book provides answers<br>for only a modest proportion of these problems. (Of course, for many of the rest the journal article on which the problem is based provides a solution!)<br>We hope that readers will think of this Solutions Manual as a trio of especially helpful lassmates. Claudio, Esteban, and Mark are people you might look for in the library when you are stuck on a problem and need some help, or with whom you want to compare<br>notes when you have hit on an especially clever argument. This is the way a generation of University of Chicago students have thought of them, and we hope that this book will let many more students, in a wide variety of places, benefit from their company as well.<br>Nancy L. Stokey<br>Robert E. Lucas</P>
