Abstract

ABSTRACT In order to study the asymmetric multifractality in maritime shipping freight rates, we have resorted to the use of the novel approach of asymmetric Multifractality Detrended Fluctuation Analysis. This approach examines the maritime shipping freight response towards the downward and upward movements. The outcomes in this regard show that the major maritime shipping freight rates have multifractals, which tend to increase as the fractal scale also increases. Also, a higher level of multifractality is observed in the downward movements for the Baltic Dry Index, and the Baltic Clean Tanker Index, suggesting that both the indexes have been less efficient, and also unpredictable during the time period pertaining to the pandemic. Moreover, the multifractality is observed to be greater in the upside for the Baltic Dirty Tanker Index during the pandemic, and also in the full-time period. The results also propagate that the maritime shipping freight rates are inefficient, a situation that has been evidently visible during the time period pertaining to the COVID-19 pandemic. The maritime shipping freight rates require special attention to monitor such sudden changes in the price dynamics, and following strict regulations is extremely critical in this regard.

新冠肺炎疫情对航运货运的影响:非对称多重分形分析
摘要为了研究海运运价的非对称多重分形,我们采用了一种新的非对称多分形去趋势波动分析方法。这种方法考察了海运货运对下行和上行的反应。这方面的结果表明,主要海运运费具有多重分形,并且随着分形尺度的增加而增加。此外,在波罗的海干散货指数和波罗的海清洁油轮指数的下降过程中,观察到了更高水平的多重分形,这表明这两个指数的效率都较低,而且在与疫情有关的时期内也是不可预测的。此外,观察到,在疫情期间,波罗的海脏油轮指数的多重分形在上行,在全职期间也更大。研究结果还表明,海运运费效率低下,这种情况在新冠肺炎大流行期间明显可见。海运运费需要特别注意监测价格动态的这种突然变化,在这方面遵守严格的规定至关重要。

期刊介绍: Thirty years ago maritime management decisions were taken on the basis of experience and hunch. Today, the experience is augmented by expert analysis and informed by research findings. Maritime Policy & Management provides the latest findings and analyses, and the opportunity for exchanging views through its Comment Section. A multi-disciplinary and international refereed journal, it brings together papers on the different topics that concern the maritime industry. Emphasis is placed on business, organizational, economic, sociolegal and management topics at port, community, shipping company and shipboard levels. The Journal also provides details of conferences and book reviews.
