中文简介:
我们探讨了以内部信贷为特征的信贷网络的特性,即连接下游(DS)和上游(US)公司的信贷关系,以及外部信贷,即连接公司和银行的信贷关系。由于首选合作伙伴选择规则,网络结构随时间变化。事实证明,DS公司的净值是增长和波动的驱动力。事实上,美国的生产是由DS公司对中间投入的需求决定的。模拟结果表明,宏观经济层面上的商业周期可能由于所涉及的代理人的异质财务状况的复杂交互作用而发展。在此背景下,我们可以研究破产链的出现。我们还可以复制企业人口统计学的主要事实:企业规模的幂律分布和增长率的拉普拉斯分布。
课程简介: We explore the properties of a credit network characterized by inside credit, i.e. credit relationships connecting downstream (DS) and upstream (US) firms, and outside credit, i.e. credit relationships connecting firms and banks. The structure of the network changes over time due to the preferred-partner choice rule. The net worth of DS firms turns out to be the driver of growth and fluctuations. US production, in fact, is determined by demand of intermediate inputs on the part of DS firms. The output of simulations shows that a business cycle at the macroeconomic level can develop as a consequence of the complex interaction of the heterogeneous financial conditions of the agents involved. In this context we can study the emergence of bankruptcy chains. We can also reproduce the main facts of firms’ demography: power law distribution of firms’ size and Laplace ditribution of growth rates.
