这么贵，而且还不能买

楼主在逗大家玩，是吗？

这本书我也有。呵。。。有点贵哟。呵。。书店应该有吧。

已经有人传过了，免费的！！！

为什么不能购买

这不是耍人吗？！无聊

传到哪儿啦？

yes, this is a good introduction to mathematical economics. Not so rigorous but easy to follow. For those who wants a more advanced but really nice one, you may try the book

mathematical methods and models for economists by de la fuente. this book will be helpful when you want to do theoretical economics.
