Abstract

This work assesses whether certain indicators constructed from unstructured information published in newspapers contain useful information regarding dynamics of Argentina’s country risk volatility, estimated from a GARCH(1,1) model. The analysis covers the period 1998-2019. One standard deviation increment in the indicator that captures manifestations of pessimism is followed by an increment of approximately 0.2% in expected country risk volatility in the consecutive quarter. Out-of-sample exercises confirm that these non-traditional indicators allow for gains in forecast accuracy. These findings are robust to changes in the set of predictors, the specification of the model and the incorporation of new media content.
基于非结构化信息的国家风险波动与指数的关系
这项工作评估了从报纸上公布的非结构化信息构建的某些指标是否包含有关阿根廷国家风险波动动态的有用信息,这些信息是通过GARCH(1,1)模型估计的。该分析涵盖1998年至2019年期间。反映悲观表现的指标每增加一个标准差,预期国家风险波动率就会在连续一个季度中增加约0.2%。样本外练习证实,这些非传统指标可以提高预测的准确性。这些发现对于预测因子集的变化、模型的规范和新媒体内容的结合都是稳健的。
