摘要
本研究介绍了一种专为发展中国家量身定制的创新型 GDP 实时预测策略,专门应对与数据及时性有限有关的挑战。研究以玻利维亚为中心,该国官方每月发布的经济增长指标延迟时间长达六个月。拟议的预报估算有效地将这一差距从 6 个月缩小到 2 个月。这一进步是通过将机器学习技术与数据(包括来自传统来源的指标和来自卫星图像的统计数据)相结合实现的。该方法的稳健性通过各种标准得到了严格验证,包括与传统计量经济学方法的性能比较以及对不同特征集的敏感性评估。除了加深对玻利维亚经济动态的了解,这项研究还为面临信息可用性挑战的地区建立了一个类似分析框架。
GDP nowcasting: A machine learning and remote sensing data-based approach for Bolivia
This research introduces an innovative GDP nowcasting strategy tailored for developing countries, specifically addressing challenges related to limited data timeliness. The study centers on Bolivia, where the official monthly indicator of economic growth is released with a substantial delay of up to six months. The proposed nowcast estimates effectively narrow this gap from six to two months. This advancement is achieved through the integration of machine learning techniques with data comprising indicators from traditional sources and statistics derived from satellite imagery. The robustness of this approach is rigorously validated using various criteria, including performance comparisons with conventional econometric methods and sensitivity assessments to different feature sets. Beyond enhancing the understanding of Bolivia’s economic dynamics, this research establishes a framework for analogous analyses in regions grappling with information availability challenges.
