Gary Becker was one of the most original and influential economists in the history of economics as a science. After Becker accomplished so much, it might seem that little would remain to do on the subject of understanding and predicting human behavior with the traditional tools of economic theory. We agree that he had extraordinary talent and, for example, undertook the study of human capital just before the market value of human capital was about to take off. But Becker taught that human capital hasmany elements of increasing returns, that initial learning many times increases the incentive to pursue additional learning. The same goes for learning the economic approach to explaining human behavior. The learning that remains is the genesis of the forthcoming book The Power of the Economic Approach: Unpublished Manuscripts of Gary S. Becker. When it comes to politics, the role of families in developing a person (her skills and preferences), fertility, and inequality, Becker was confident that some of the finest applications of economics had not yet arrived. He kept working to find breakthroughs. Each previously unpublished document in this book is an instance where he identified a direction of inquiry that had a good chance of success, but he did not

经济方法的力量示例：加里·贝克尔（Gary S. Becker）的未出版手稿，由朱利奥·J·埃利亚斯（Julio J.Elías），凯西·B·穆里根（Casey B. Mulligan）和凯文·墨菲（Kevin M. Murphy）编辑，芝加哥大学出版社（即将出版）

加里·贝克尔（Gary Becker）是经济学史上最有影响力的经济学家之一。在贝克尔取得了如此大的成就之后，似乎无法用传统的经济理论工具来理解和预测人类行为这一话题。我们同意他具有非凡的才能，例如，在人力资本的市场价值即将腾飞之前就进行了人力资本研究。但是贝克尔（Becker）指出，人力资本有许多增加回报的要素，许多次的初始学习增加了追求额外学习的动力。学习解释人类行为的经济方法也是如此。剩下的知识来自即将出版的《经济方法的力量：未发表的加里·贝克尔手稿》一书。在政治，家庭在培养人格方面的作用（她的技能和偏好），生育能力和不平等方面，贝克尔深信某些最出色的经济学应用尚未出现。他一直在努力寻找突破。本书中每个以前未出版的文档都是一个实例，在此实例中，他确定了一个很有可能成功的查询方向，但他没有
