摘要
由于 COVID-19 大流行病的数据有限但影响巨大,基于经济指标的标准经济衰退预测变得不稳定。本文提出了一种新的非参数方法来计算未来经济衰退的预测概率,这种方法对有影响的观测数据和其他不规则数据具有鲁棒性。该方法利用嵌入符号空间的过去数据历史模拟预测。然后,将预测转换为概率声明,并根据各自符号的预测概率进行加权。利用七国集团的 GDP 数据,我们的建议在对未来国家商业周期阶段进行分类方面优于其他参数方法,尤其是将 2020 年的数据纳入样本。
A New Approach to Forecasting the Probability of Recessions after the COVID-19 Pandemic*
Standard recession forecasting based on economic indicators has become unsettled due to COVID-19 pandemic's limited but influential data. This paper proposes a new non-parametric approach to computing predictive probabilities of future recessions that is robust to influential observations and other data irregularities. The method simulates forecasts using past data histories embedded into a symbolic space. Then, the forecasts are converted into probability statements, which are weighted by the forecast probabilities of their respective symbols. Using GDP data from G7, our proposal outperforms other parametric approaches in classifying future national business cycle phases, especially including data from 2020 in the sample.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
