Abstract
ABSTRACT We developed a market sentiment measure for freight markets of the dry bulk shipping segment. Initially, keywords with positive and negative sentiment connotation were identified, and their relative importance was estimated, by administering two surveys with industry stakeholders. Next, a self-developed search algorithm software was developed to scan over 9,500 articles in shipping press, during 2008–2018, in order to calculate keywords’ frequencies. Following the construction of the sentiment measure, its validity was assessed with a system of simultaneous equations. Among others, our empirical results indicate a bidirectional relationship between market sentiment and maritime seaborne economic activity. The findings yield important implications for practitioners in maritime shipping industry.
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.
