There is a much nicer alternative treatment in J.M.Blatt: Dynamic Economic Systems, which uses Leontief matrices.

The book I got recommended from Steve Keen, when I asked him a similar question, was J.M.Blatt: Dynamic Economic Systems. Although he has beautifully simple approach, it is really outside the standard economic theory and apart from Keen and perhaps few other individuals, sadly no one really follows in Blatt's footsteps.
…it's just a language barrier. In economics, I wish more people knew about (I don't know the name, unfortunately) the approach to calculating of equilibrium prices that is described in J.M.Blatt's book Dynamic Economic Systems, and is based on input-output production matrices. It's a much more superior approach to the classical supply-demand analysis that dominates the textbooks, because it requires much less free parameters…
…has the demand curve shifted, has the supply curve shifted? The problems of general equilibrium approach are quite succinctly described in Keen: Debunking Economics. And compared to approach in Blatt: Dynamic Economic Systems, it's a disaster - too many parameters and assumptions for too little explaining power. It was a pretty decent way to describe the world when Walras came up with it; but it should have been obsoleted…
……理论。如果你想看一个完全更胜一筹的替代方案（能得出直觉上相似的结果甚至更多，参数更少且更容易扩展），我建议看看 Blatt 的《Dynamic Economic Systems》第一部分的处理方式。（这也是 Steve Keen 推荐给我的，天哪，写得太牛了。Keen 可能不合所有人口味，但每个学经济的人都该读读 Blatt。他是所有人中最被遗忘的……
…theory. And if you want see alternative, which is completely superior (gives intuitively similar results and more, requires less parameters and is easier to extend), I suggest the treatment in Blatt: Dynamic Economic Systems, first part. (This was also suggested to me courtesy of Steve Keen, but boy, it is good. Keen is not to everybody's taste, but everyone in economics should read Blatt. He is the most forgotten of all…
…more innovation. Sorry, I thought that was obvious. It isn't obvious at all. In fact, there are some indications that the opposite is true. For example, there are some simple economic models in Blatt:Dynamic Economic Systems where rate of profit and rate of growth are inversely proportional. Also, data from Piketty aren't very optimistic in this sense either (it seems that economic states with lots of private capital correspond…

我问过 Steve Keen 类似的问题，他推荐给我的书是 J.M.Blatt 的《Dynamic Economic Systems》。虽然他的方法精妙简洁，但确实完全脱离了主流标准经济学理论，而且遗憾的是，除了 Keen 和少数几个人，几乎没人继承 Blatt 的衣钵。

……这只是语言障碍。在经济学领域，我希望有更多人了解 J.M.Blatt 在《Dynamic Economic Systems》一书中所描述的均衡价格计算方法（很遗憾我不知道具体叫什么名字），它是基于投入产出生产矩阵的。相比统治教科书的传统供求分析，这种方法要优越得多，因为它需要的自由参数少得多……

……需求曲线移动了吗？供给曲线移动了吗？一般均衡方法存在的问题在 Keen 的《Debunking Economics》里讲得相当透彻。跟 Blatt 在《Dynamic Economic Systems》里的方法比起来，它简直是一场灾难——参数和假设太多，解释力却太弱。瓦尔拉斯（Walras）刚提出它的时候用来描述世界还算不错，但早就该被淘汰了……

……更多创新。抱歉，我还以为这是显而易见的。其实一点都不明显。事实上，有迹象表明事实恰恰相反。例如，在 Blatt 的《Dynamic Economic Systems》里有一些简化的经济模型，其中利润率与增长率成反比。而且，皮凯蒂（Piketty）的数据从这个角度来看也不太乐观（似乎拥有大量私人资本的经济状态对应着……
