项目摘要

The project uses modeling techniques originally developed in physics to understand the growth of business firms. Physicists have analyzed systems in which the behavior of one "unit" (an atom, perhaps) is affected by the behavior of a large number of other units. The effect of each individual interaction may be small, but the aggregate effect is not. By analogy, the growth of each business firm is affected by a large number of other firms: competitors, customers, suppliers, and the producers of related products. In 1939, Coase published a seminal article in which he argued that firms exist to minimize transaction costs. This article provided the framework that economists still use to try to understand the size and growth of firms. Even though the logic of this framework is widely accepted, it has not yielded testable predictions about the size and growth of individual firms that have been verified empirically. In other words, it has not passed the fundamental test of a successful scientific theory. The results in models of physical systems with large numbers of interacting units are that while the behavior of any one unit is inherently unpredictable, the statistical properties of the entire system are predictable. This project develops models that are consistent with the framework suggested by Coase, that explain well-documented regularities about the distribution of firm size and growth, and that explain why the growth, size, and composition of individual firms are inherently unpredictable. While this project is basic research, the results could ultimately affect antitrust and other aspects of industrial policy.
该项目使用最初在物理学中开发的建模技术来了解商业公司的增长。 物理学家分析过这样的系统,其中一个“单元”(也许是原子)的行为受到大量其他单元行为的影响。 每一个单独的相互作用的影响可能很小,但总的影响是不小的。 以此类推,每个企业的成长都受到大量其他企业的影响:竞争对手、客户、供应商和相关产品的生产商。 1939年,科斯发表了一篇开创性的文章,他认为企业的存在是为了最大限度地降低交易成本。 这篇文章提供了一个框架,经济学家仍然使用它来试图理解企业的规模和增长。 尽管这一框架的逻辑被广泛接受,但它并没有产生关于单个企业的规模和增长的可检验的预测,这些预测已经得到了经验的验证。 换句话说,它还没有通过一个成功的科学理论的基本检验。 具有大量相互作用单元的物理系统模型的结果是,虽然任何一个单元的行为本质上是不可预测的,但整个系统的统计特性是可预测的。 该项目开发的模型与科斯提出的框架一致,解释了关于企业规模和增长分布的有据可查的理论,并解释了为什么单个企业的增长,规模和组成本质上是不可预测的。 虽然该项目是基础研究,但其结果可能最终影响反垄断和产业政策的其他方面。
