Ethical and safety climate should be taken into account by yacht organizations to improve the perceptions of yacht crews. The findings show that ECP and SC have a positive effect on the PWB of yacht crews. From this perspective, this study suggests that yacht organizations should involve their crews in their ethical decisions to foster an ECP. Yacht businesses should act consistently in all areas and adopt clear safety and ethical rules and procedures for yacht crews to follow to create a perception of ethical and safety climate.</p><!--/ Abstract__block --><h3>Social implications</h3><p>This study contends that yacht crews, who face lengthy shifts and professional duties, are a component of the tourism and maritime industries.

目的 本研究旨在探讨心理资本(PC)和安全氛围(SC)在商业游艇船员心理健康感知(PWB)和道德氛围感知(ECP)之间的调节作用。数据来自土耳其的 339 名游艇船员。研究结果本研究揭示了 SC 和 PC 在游艇船员的 PWB 和 ECP 之间的因果关系中的作用,游艇船员作为旅游业和海运业的从业人员,理应表现出积极的组织态度和行为。游艇船员在工作环境中的工作能力受其 SC 和 PC 水平的影响。研究局限性/启示虽然本研究的整体模型很有说服力,但也存在一些局限性。样本仅包括土耳其游艇组织中的土耳其游艇船员。游艇船员定期在恶劣的条件下工作。我们从经历过挑战性环境的游艇船员那里获得了研究数据,因此,研究结果是针对这些船员的。不同文化背景下的道德观念和标准可能会有所不同;因此,未来针对不同组织员工的研究可能会得出不同的结果。本研究的意义在于它测试了一个综合模型。游艇组织应考虑道德和安全氛围,以改善游艇船员的看法。研究结果表明,ECP 和 SC 对游艇船员的 PWB 有积极影响。从这一角度出发,本研究建议游艇组织让船员参与道德决策,以促进 ECP。游艇企业应在所有领域采取一致行动,并制定明确的安全和道德规则和程序,供游艇船员遵守,以营造道德和安全氛围。 社会意义 本研究认为,游艇船员面临着长时间的轮班和专业职责,是旅游和海事行业的组成部分。研究结果表明,有必要针对影响公共福利预算的因素,从员工的不同角度开展更多研究。有关游艇船员及其 PWB、SC、ECP 和 PC 等人格结构之间关系的数据相对较少。本研究表明,游艇船员在压力大、要求高的工作环境中的工作能力取决于积极的 ECP 和通过 SC 实现的高 PC。它还旨在填补研究空白,并在旅游和海事文献的基础上,对游艇船员和 PWB 以及旅游和海事背景下的气候进行研究。

<h3>Purpose</h3><p>Container liner shipping companies started expanding their business by investing in container port terminals in the late 1990s. This market entry results in an extensive presence of vertically integrated liners and terminals. This study aims to explore the competition effects of this vertical integration trend based on a regional (European) analysis. In particular, it extracts lessons from the European Commission (EC) cases on the competition effects of vertical integration. The critical analysis of the cases examined at the institutional level intends to reach conclusions on whether liner–terminal vertical integration harmed or advanced competition in the relevant markets and/or the extent that there is a need to revise the current policy practices.</p><!--/ Abstract__block --><h3>Design/methodology/approach</h3><p>This study critically assesses the EC’s decisional practices in port container terminal vertical mergers in the last 25 years (1997–2021). Based on a literature review comparing maritime and competition economists' perspectives, it reviews the types of mergers examined, the methodology followed for relevant market definition and calculation of market shares, and the estimated competition effects.

目的集装箱班轮航运公司从 20 世纪 90 年代末开始通过投资集装箱港口码头来扩展业务。这种市场进入导致班轮公司和码头纵向一体化的广泛存在。本研究旨在通过区域(欧洲)分析,探讨这种纵向一体化趋势对竞争的影响。特别是,它从欧盟委员会(EC)关于纵向一体化竞争影响的案例中汲取了教训。本研究从制度层面对案例进行了批判性分析,旨在就班轮码头纵向一体化是损害还是促进了相关市场的竞争,以及/或在多大程度上需要修改现行政策实践得出结论。在对海运经济学家和竞争经济学家的观点进行文献综述的基础上,本研究回顾了所审查的兼并类型、相关市场定义和市场份额计算方法,以及所估算的竞争效应。汉堡-勒阿弗尔地区是用于比较决策实践与实际市场发展的案例研究港口范围。这些集装箱港口服务于欧洲最大的最终产品和中间产品消费市场,是通往中欧和东欧的门户。评估结果表明,有必要扩大调查范围,这是得出反竞争效应和有利竞争效应结论的前提条件。首先,向欧盟委员会通报的交易数量有限。其次,实证研究发现了这一过程中的空白,因为在 2008 年至 2016 年期间,没有关于纵向兼并的决定(第一阶段)。第三,由于不存在竞争问题,事前评估没有对任何案例进行第二阶段的深入分析。最后,由于没有投诉,也就没有对纵向一体化的影响进行事后评估。这些讨论对使用班轮航运服务或为集装箱航运公司或港口提供设施和服务的各类企业至关重要。这些讨论对客户和消费者的利益非常重要,因为它们可以为重新审视竞争政策提供所需的信息,以防止市场发展的主导地位导致限制竞争的条件。从消费者的角度来看,加强竞争和限制垄断是有价值的。对于服务于社会需求的海上贸易而言,更是如此。本研究有助于更好地了解决策者是如何朝着这个方向努力的,以及哪些调整是值得的。原创性/价值在从消费者角度看加强竞争是有价值的情况下,区域层面的决策者是如何应对班轮公司纵向一体化战略的竞争影响的,此前还没有全面的回顾和分析。比较海洋经济学家与竞争。本研究还通过文献综述,比较了海事和竞争对这些竞争效应的影响,从而对决策实践的有效性进行了定位。

Purpose

The COVID-19 pandemic had a disastrous impact on a substantial number of Filipino seafarers. The government agencies played a crucial role in helping the seafarers. This paper aims to explore the challenges that the Filipino seafarers faced amid the pandemic, and initially evaluate the Philippine government’s countermeasures.

Design/methodology/approach

This paper reviewed academic literature and secondary data to identify and analyze the impact of the COVID-19 pandemic on seafarers. To identify the full range of policies and measures that have been adopted by the Philippines’ government amid the pandemic to mitigate the impact on seafarers, an extensive survey of various sources was conducted. Furthermore, an analytic hierarchy process (AHP) survey was conducted from seafarers' perspective to analyze the priority of these government initiatives.

Findings

This study identifies four key challenges for seafarers during the pandemic: crew change crisis, healthcare shortages, certification and the derived problems including financial and mental health issues. Notably, mental health problems are prevalent but receive limited government attention. Despite the government’s efforts to assist seafarers, the AHP survey identifies crew change assistance as the most crucial issue, possibly impacting all others.

Originality/value

This paper recognizes the significant information regarding aid in recovery management, and provides much-needed assistance to seafarers during the pandemic and similar crisis situations. It bridges the research gaps and contributes knowledge to the government, stakeholders and various entities such as shipping companies, ship management firms and seafarers' manning agencies.

目的 COVID-19 大流行对大量菲律宾海员造成了灾难性影响。政府机构在帮助海员方面发挥了关键作用。本文旨在探讨菲律宾海员在疫情中面临的挑战,并初步评估菲律宾政府的应对措施。本文通过查阅学术文献和二手资料,确定并分析 COVID-19 疫情对海员的影响。为了确定菲律宾政府在大流行病期间为减轻对海员的影响而采取的各种政策和措施,对各种资料来源进行了广泛调查。此外,还从海员的角度进行了层次分析法 (AHP) 调查,以分析这些政府举措的优先次序。研究结果本研究确定了大流行病期间海员面临的四大挑战:船员变更危机、医疗保健短缺、认证以及包括财务和心理健康问题在内的衍生问题。值得注意的是,心理健康问题普遍存在,但政府对其关注有限。尽管政府在帮助海员方面做出了努力,但 AHP 调查发现,船员变更援助是最关键的问题,可能会影响到所有其他问题。 原创性/价值 本文确认了有关恢复管理援助的重要信息,并在大流行病和类似危机情况下为海员提供了急需的援助。它填补了研究空白,并为政府、利益相关者以及航运公司、船舶管理公司和海员配员机构等各种实体提供了知识。

Purpose

This paper aimed to assess the service quality of the main seaports in Oman, which were Sohar, Ad Duqm and Salalah. The aim was to come up with ways to enhance the port service quality (PSQ) in Oman so that it could align with the Sultanate of Oman logistics strategy (SOLS) 2040 goals and achieve excellent and efficient operations.

Design/methodology/approach

To evaluate the service quality level of the port operators, this paper used a descriptive research design with Resources, Outcome, Process, Management, Image/reputation and Social (ROPMIS) modelling.

Findings

The findings indicated that the overall PSQ rating was currently between “satisfactory” and “very satisfactory” levels. However, the study also found that by empowering resources, outcomes, processes, management, image and social responsibility aspects, the port operators could provide a “high” quality of service, making their seaport operations more effective and efficient.

Practical implications

The study offers recommendations for improving port services in Oman, including investment in modern seaports, upgrading infrastructure and facilities, ensuring safety and efficiency of cargo operations, meeting and exceeding customer expectations, adopting new technology and automation, hiring policies that attract diverse talents, implementing environmentally friendly practices, and improving governance. Overall, this study contributes to the literature and managerial practices in PSQ aspects and its contribution to the SOLS 2040 in Oman.

Originality/value

The originality and novelty of this study lie in its comprehensive assessment of the service quality of Oman's ports and the identification of areas for improvement to achieve outstanding service levels.

PurposeThis paper aims to identify the interplay of standard Capesize optimal speeds for time charter equivalent (TCE) maximization in the Australia–China iron ore route and the optimal speeds as an operational tool for compliance with the International Maritime Organization (IMO) carbon intensity indicator (CII).Design/methodology/approachThe TCE at different speeds have been calculated for four standard Capesize specifications: (1) standard Capesize with ecoelectronic engine; (2) standard Capesize with non-eco engine (3) Standard Capesize vessel with an eco-electronic engine fitted with scrubber and (4) Standard Capesize with non-eco engine and no scrubber fitted.FindingsCalculations imply that in a highly inflationary bunker price context, the dollar per ton freight rates equilibrates at levels that may push optimal speeds below the speeds required for minimum CII compliance (C Rating) in the Australia–China trade. The highest deviation of optimal speeds from those required for minimum CII compliance is observed for non-eco standard Capesize vessels without scrubbers.

目的 本文旨在确定标准海岬型船在澳大利亚-中国铁矿石航线上实现时间包租当量(TCE)最大化的最佳速度的相互作用,并将最佳速度作为符合国际海事组织(IMO)碳强度指标(CII)的操作工具。设计/方法/途径计算了四种标准海岬型船规格在不同航速下的 TCE:(1) 装有生态电子发动机的标准海岬型船;(2) 装有非生态发动机的标准海岬型船;(3) 装有生态电子发动机且配有洗涤器的标准海岬型船;(4) 装有非生态发动机且未安装洗涤器的标准海岬型船。研究结果计算表明,在燃油价格高度通胀的情况下,每吨美元运费的平衡水平可能会使澳中贸易中的最佳航速低于符合 CII 最低标准(C 级)所需的航速。没有洗涤器的非环保标准海岬型船的最佳航速与符合 CII 最低要求的航速偏差最大。虽然大多数研究都涉及使用航速作为工具来提高海运业的效率和排放,但很少有文献研究了干散货行业因货运市场平衡而产生的商业和运营绩效之间的相互作用。本文的独创性在于研究了上述关系,以及由此产生的海岬型船部门针对强制性环境目标的最佳速度选择。

The enhanced role of canals and route choice due to disruptions in maritime operations 由于海上作业的中断,运河和航线选择的作用增强
IF 3 Q3 BUSINESS Pub Date : 2023-12-05 DOI: 10.1108/mabr-01-2023-0008
Thalis P.V. Zis

Purpose

This paper focusses on the aftermath of disruptions and the importance of the two largest canals (Suez and Panama), commenting on how during the pandemic the canal fees were lowered. Considering the ongoing efforts to decarbonize shipping, some of the ongoing disruptions will help reach these objectives faster.

Design/methodology/approach

Following a literature review of route choice in shipping, and a presentation of significant disruptions in recent years, the author deploys a simplified fuel consumption model and conduct case study analyses to compare different routes environmentally and economically.

Findings

The results explain why at times of low fuel prices as in 2020, canals provided discounts to entice ship operators to keep transiting these, instead of opting for longer routes. Considering the ongoing repercussions of the pandemic in supply chains, as well as the potential introduction of market-based measures in shipping, the value of transiting canals will be much higher in the coming years.

Research limitations/implications

The main limitation in this work is that the author used the publicly available information on canal tolls, for the different ship types examined.

Practical implications

The envisioned model is simple, and it can be readily used for any ship and route (port to port) combination available, if ship data are available to researchers.

Social implications

It is possible that canal tolls will increase, to account for the additional environmental benefits brought to ship operators.

Originality/value

The methodology is simple and transferable, and the author proposes several interesting research questions for follow-up work.

本文重点讨论了运河中断的后果和两条最大运河(苏伊士运河和巴拿马运河)的重要性,并评论了大流行期间运河费是如何降低的。考虑到目前正在努力使航运脱碳,一些持续的中断将有助于更快地实现这些目标。在对航运路线选择的文献回顾和近年来重大中断的介绍之后,作者部署了一个简化的燃料消耗模型,并进行了案例研究分析,以比较不同的路线在环境和经济上。研究结果解释了为什么在2020年这样的低油价时期,运河会提供折扣,以吸引船舶运营商继续通过这些航线,而不是选择更长的航线。考虑到疫情对供应链的持续影响,以及可能在航运领域采取基于市场的措施,未来几年过境运河的价值将大大提高。这项工作的主要限制是作者使用了关于运河通行费的公开信息,用于研究不同类型的船舶。设想的模型很简单,如果研究人员可以获得船舶数据,它可以很容易地用于任何船舶和路线(港口到港口)组合。社会影响考虑到给船舶经营者带来的额外环境效益,运河通行费可能会增加。原创性/价值方法简单,可转移,作者提出了几个有趣的研究问题,为后续工作。

Trade effects of liner shipping across world regions 班轮运输对世界各地区贸易的影响
Q3 BUSINESS Pub Date : 2023-11-08 DOI: 10.1108/mabr-06-2023-0040
Ignacio Del Rosal
Purpose Liner shipping plays a crucial role in facilitating the movement of manufactured goods around the world. While previous literature has shown that liner shipping is an important trade driver, potential differences across trade routes and world regions have not as yet been explored. This paper examines whether the impact of liner shipping on bilateral trade flows differs significantly across world regions, as well as exploring other geographical patterns. Design/methodology/approach Using state-of-the-art gravity modelling, this paper investigates the impact of the UNCTAD's Liner Shipping Bilateral Connectivity Index on bilateral trade in manufactured goods using a comprehensive database of disaggregated trade data for the period from 2006 to 2019. Findings The results show that the trade effect of liner shipping is greater in long-distance and interregional bilateral flows. For some regions, such as North America and Oceania, the effect is greater than the world average, while for others, such as Africa and South America, the effect is significantly smaller. The trade effects of liner shipping connectivity on the main east–west routes are average, but clear asymmetry emerges when analysing China's inward and outward trade flows separately. Originality/value The results of this paper show that the major east–west routes determine the baseline trade effects of liner shipping, demonstrate that some north–south trades such as those involving Oceania generate larger trade effects and confirm that the trade effects of liner shipping can be improved for some world regions such as South America and Africa.
班轮运输在促进制成品在世界各地的流动方面起着至关重要的作用。虽然以前的文献表明班轮运输是一个重要的贸易驱动因素,但尚未探索贸易路线和世界地区之间的潜在差异。本文考察了班轮运输对双边贸易流动的影响在世界各地是否存在显著差异,并探讨了其他地理模式。本文采用最先进的重力模型,利用2006年至2019年期间分类贸易数据的综合数据库,研究了贸发会议班轮航运双边连通性指数对双边制成品贸易的影响。结果表明,班轮运输在区域间和长距离双边流动中的贸易效应更大。对于一些地区,如北美和大洋洲,影响大于世界平均水平,而对于其他地区,如非洲和南美洲,影响要小得多。在东西向主要航线上,班轮运输互联互通的贸易效应是平均的,但在分别分析中国的对内和对外贸易流动时,明显出现了不对称。本文的研究结果表明,主要的东西航线决定了班轮运输的基线贸易效应,表明一些南北贸易(如涉及大洋洲的贸易)产生了更大的贸易效应,并证实班轮运输的贸易效应可以改善一些世界地区(如南美和非洲)。

The announcement effect of shipping sale-and-leaseback transactions 本公告影响船舶售后回租交易
Q3 BUSINESS Pub Date : 2023-10-23 DOI: 10.1108/mabr-07-2023-0051
Sangho Yoon, Chi Yeol Kim
Purpose This paper investigates the announcement effect of shipping sale-and-leaseback (SLB) transactions. As an emerging source of financing, a growing deal of interest has been paid to the SLB. However, little is known about a variety of aspects of SLB transactions in the shipping industry. In this regard, this study examines the stock market reaction to the SLB announcements of shipping firms and their impact on shareholders' wealth. Design/methodology/approach A sample of 15 shipping SLB deals commenced by publicly-listed Korean shipping companies during 2009–2023 are examined in this research. The announcement effect is measured by abnormal returns (AR) of their stocks based on the event study analysis. Findings It is found that the AR on the shipping SLB announcement date is, on average, −0.84% while there is no statistical significance. However, the results indicate that shareholders of shipping companies engaging in large-sized SLBs can experience positive AR around the announcement date. Originality/value This study is the first attempt to investigate the announcement effect of SLB transactions on the shipping industry and their impact on shareholders' wealth. The findings in this research can offer implications for the financing decisions of shipping companies and investment decisions of stock investors.

Purpose In the shipping industry, both sales and purchases of second-hand ships and freight transport services are prevalently tailor-made and traded with intense bilateral negotiations. Price bargaining is the key step of this negotiation process and plays a crucial role in determining mutually agreed prices. Despite its cruciality and applicability, the price bargaining has yet received due conceptual and/or theoretical attention in the shipping literature. This paper attempts to conceptually examine the role of bargaining in shipping transaction prices and subsequently puts forward directions for future research. In doing so, the paper focuses on two types of transactions taking place in shipping markets: asset market trading of second-hand vessels and service market trading shipping freights. Design/methodology/approach The paper begins with a systematic literature review of price bargaining in the field of economics and management disciplines from a game-theoretic perspective. This approach does logically lead to the establishment of a conceptual framework for price bargaining in shipping sub-markets as a step toward having taken into consideration a variety of heterogeneities commonly present in trading activities and market dynamics. Findings A set of research areas has been consequently identified where price bargaining and mechanisms for the shipping freight and asset markets could be further explored and analyzed in a way to make better pricing decisions under a more tangible framework. Research limitations/implications One of the critical challenges when using bargaining mechanisms to make a decision on pricing shipping services and assets is how to operationalize the study for empirical investigation as some of the factors are internal information of the players and are not adequately revealed to externals: that is, an imperfect information sharing case. The current study aims, however, not to conduct an empirical analysis but to initiate a conversation among maritime economists by bringing their attention to this not-yet fully explored and potentially impactful field of research and by asking them to treat bargaining from a perspective for pricing shipping assets and services. It is claimed that, by doing so, one could better understand price differences between individual contracts. Originality/value This study would be considered the first in its kind to provide a detailed survey of the bargaining theory and models from a game theoretical perspective as a theoretical lens to understand its importance and relevance in pricing shipping assets and services. It also provides a simplified operational case on utilizing bargaining in practically pricing freight services.
在航运业,二手船舶的买卖和货运服务普遍是量身定制的,并通过激烈的双边谈判进行交易。议价是谈判过程中的关键一步,在确定双方商定的价格方面起着至关重要的作用。尽管其重要性和适用性,价格议价在航运文献中尚未得到应有的概念和/或理论关注。本文试图从概念上考察议价在航运交易价格中的作用,并提出未来研究的方向。为此,本文重点关注航运市场中发生的两类交易:二手船舶的资产市场交易和航运运费的服务市场交易。本文首先从博弈论的角度对经济学和管理学领域的价格议价进行了系统的文献综述。这种方法在逻辑上确实导致建立航运次级市场价格议价的概念框架,作为考虑到贸易活动和市场动态中普遍存在的各种异质性的一步。因此,已经确定了一系列研究领域,在这些领域中,可以进一步探索和分析航运运费和资产市场的议价和机制,以便在更具体的框架下作出更好的定价决定。当使用议价机制来决定航运服务和资产的定价时,一个关键的挑战是如何将研究用于实证调查,因为一些因素是参与者的内部信息,并没有充分向外部披露:即,一个不完全的信息共享案例。然而,当前研究的目的不是进行实证分析,而是通过引起海事经济学家对这一尚未充分探索和潜在影响的研究领域的关注,并要求他们从航运资产和服务定价的角度来对待议价,从而在海事经济学家之间发起对话。据称,通过这样做,人们可以更好地理解个别合同之间的价格差异。本研究将被认为是同类研究中第一次从博弈论的角度对议价理论和模型进行详细调查,作为理论视角来理解其在航运资产和服务定价中的重要性和相关性。并提供了在实际货运服务定价中运用议价的简化操作案例。
