摘要
摘要:本文以2008年1月至2018年6月15个发达经济体和主要新兴市场经济体为样本,研究了系统性风险、经济政策不确定性和企业破产之间的因果关系。我们在时间和频域中测试格兰杰因果关系,并通过应用一种新技术-收敛交叉映射(Sugihara et al., 2012)来剖析动态复杂系统框架中的多变量因果关系。基于这三种方法的严格一致的结果,我们发现西班牙的系统性风险导致企业退出,而英国和荷兰的破产是由经济政策的不确定性引发的。在韩国和美国,波动率指数导致企业倒闭。对于其他国家,因果关系推理提供的证据不那么有力。我们认为,银行相对于私人非金融部门的去杠杆化程度,由信贷与gdp之差的波动性所代表,决定了系统性风险、经济政策不确定性或VIX指数对破产的因果影响的存在与否。
Systemic Risk, Economic Policy Uncertainty and Firm Bankruptcies: Evidence from Multivariate Causal Inference
Abstract The paper investigates causal relationships between systemic risk, economic policy uncertainty and firm bankruptcies, conditional on global volatility proxied by the VIX index, in a sample of 15 advanced and major emerging market economies during January 2008-June 2018. We test for Granger causality in time and frequency domains as well as dissect multivariate causal linkages in the dynamic complex system framework by applying a novel technique – convergent cross mapping ( Sugihara et al., 2012 ). Based on strictly coincident results from all the three approaches, we find that systemic risk causes firm exit in Spain, while in the UK and the Netherlands bankruptcies are triggered by economic policy uncertainty. In South Korea and the USA, the VIX index causes the firm shutdown. For the rest of the countries, the causality inference provides less robust evidence. We argue that the magnitude of deleveraging by banks with respect to the private nonfinancial sector, proxied by the volatility of credit-to-GDP gaps, shapes the presence or absence of causal impact by systemic risk, economic policy uncertainty or the VIX index on bankruptcies.
