英文摘要:
We propose a simple dynamical model of the formation of production networks among monopolistically competitive firms. The model subsumes the standard general equilibrium approach \\`a la Arrow-Debreu but displays a wide set of potential dynamic behaviors. It robustly reproduces key stylized facts of firms\' demographics. Our main result is that competition between intermediate good producers generically leads to the emergence of scale-free production networks.

中文摘要:
我们提出了垄断竞争企业之间生产网络形成的简单动力学模型。该模型包含了标准的一般均衡方法“la Arrow Debreu”,但显示了一系列潜在的动态行为。它有力地再现了企业人口统计的关键程式化事实。我们的主要结果是,中等商品生产者之间的竞争通常会导致无标度生产网络的出现。
