Estimation of the perceived value of transit time for containerized cargoes

This paper proposes a novel method for estimating the perceived value of transit time of containers by shipping lines. The key idea is that a shipping line’s published schedule is the optimal decision that minimizes the sum of fuel cost and time-associated costs of the containers adopted by the shipping line. Using the proposed method, we find that the adopted values of transit time for nine trans-Pacific services operated by Orient Overseas Container Line and five trans-Pacific services operated by Maersk Line are between US$5/TEU/day and US$30/TEU/day. We further demonstrate how the adopted value can be used for designing the optimal transit times between ports, analyzing the viability of slow-steaming, checking whether ships should speed up to catch up to connecting ships on other services, and helping to predict the market share of less polluting fuels in view of rules on air emission.     

跨国公司对华投资战略调整问题研究

跨国公司既是经济全球化的的载体又是直接推动者。21世纪在经济全球化的背景下，众多跨国公司敏感地意识到未来中国蕴藏的巨大商机，纷纷开始调整对华投资战略。特别是我国加入WTO之后，跨国公司这种对华投资战略调整趋势愈发明显，对中国经济的影响也日渐显现出来。因此，应在深入分析跨国公司对华投资战略调整的新趋势及其原因的基础上，制定合理的利用外资的政策，积极稳妥地利用跨国公司的投资，更好地促进我国经济的持续快速发展。

资产管理公司半政策性半商业性收购不良资产方式分析

为了有效防范和化解金融风险,支持渐进转轨的顺利进行,就必须存在一个不是按照商业原则,而是根据政府偏好运作的资产管理公司,因此资产管理公司政策性收购和政策性处置均具有必然性。而随着体制转轨的不断深入和国有银行商业性不良资产的增加,二次剥离中采取了半政策性和半商业性相结合的方式也是符合整个渐进转轨逻辑的。

Meta-frontier function approach to operational efficiency for shipping companies

ABSTRACT

This study uses a meta-frontier function approach to estimate operational efficiency and technology gaps for shipping companies. Researchers have evaluated the relative efficiency of shipping firms with the assumption that shipping firms operate under one frontier technology. However, the assumption of one frontier technology is being argued by efficiency literature. Therefore, this study estimates relative efficiency of shipping firms in different market segments (dry bulk, liquid bulk, and containerized cargo), possibly operating with different technologies and, hence, under different frontiers. This study uses a meta-frontier function approach that allows us to distinguish separate frontiers for different groups and decompose efficiency scores relative to the meta-frontier. Data used in this study is collected from Thomson One Banker from 2001-2013 in the form of unbalanced panel data. Empirical results suggest that dry bulk firms’ production technology is more advanced than others and the production frontier is the closest to that of the meta-frontier. In addition, efficiency scores are all low, but containerized cargo firms achieve higher technological efficiency than the other two groups. It is also suggested that containerized cargo and liquid bulk firms should prioritize improvements in their production technology and dry bulk firms should prioritize improving group efficiency.
