Data for: Evolution in a General Equilibrium framework

Is an evolutive model in the framework of the General Equilibrium Theory In this work, we consider a general equilibrium model in which an economy is characterized by the distribution of firms on the branches of industry. We will show that it is possible to build a dynamic based on the decisions of the managers or owners of the firms. Their investment decisions will cause the distribution of the firms in the branches of production to be modified, which will result in price changes. In a neighborhood of a singularity, these decisions, even when they are small, could lead to abrupt and unexpected changes in the behavior of the economy. It is for this reason that we say that singular economies are the prelude to economic crises. In opposite, in a neighborhood of a regular economy, small changes in the decisions of the managers do not imply big changes in the posterior behavior of the economy.本研究的演化模型基于一般均衡理论（General Equilibrium Theory）框架展开。本研究构建的一般均衡模型中，经济体以各产业部门的企业分布作为核心表征。研究表明，可构建一套基于企业管理者或所有者决策的动态演化机制。企业的投资决策将改变各生产部门的企业分布格局，进而引发价格波动。在奇异经济体（singular economy）的邻域内，即便企业决策规模微小，也可能引发经济体运行态势出现突发性、非预期的剧烈变化。正因如此，我们认为奇异经济体是经济危机的前兆。与之相反，在正则经济体（regular economy）的邻域内，企业管理者的微小决策调整并不会引发经济体后续运行态势出现显著变化。
