This paper estimates time-varying and constant hedge ratios, and investigates their performance in reducing freight rate risk in routes 1 and 1A of the Baltic Freight Index. Time-varying hedge ratios are generated by a bivariate error correction model with a GARCH error structure. We also...

This paper presents an analysis of the perceptions held by for-hire and private trucking company logistics and operations managers about the impacts of congestion on their operations and the feasibility and effectiveness of actual and potential congestion mitigation policies. Responses to an...

We propose a new method of modeling the relationship between on-time performance and market share in the airline industry. The idea behind the method is that the passengers' decision to remain (use same airline) or switch (use other airlines) at time t depends on whether they have experienced...

This paper extends previous works that view transit systems as minimizing their after-subsidy costs. The paper uses the expense preference behavior model in economics and derives first-order conditions for the manager. From the first-order conditions, the paper formally shows that the...

In this paper, we provide another reason that may explain the adoption of the hub-and-spoke network structure in the airline industry. We show that when an airline has to decide on its capacity before the demand conditions are perfectly known, a hub-and-spoke (h&s) network structure by pooling...

This paper empirically assesses the economic size (in terms of full time equivalent employees (FTEs)) of postponed manufacturing applications and related activities. Based on a survey among 782 companies, the differences in size and scope of applications between manufacturers, wholesalers and...

The virtual warehouse (VW) is a state of real-time global visibility for logistics assets such as inventory and vehicles. The efficiency of the VW is comparable to that achieved in a local warehouse facility. We assess the enabling technologies, develop a conceptual framework, and identify the...

Following important changes in the safety regulation of tankers, the dry bulk sector is coming under the spotlight in a safety and quality perspective. Nominal freight differentiation between 'quality' and 'other' tonnage has been observed occasionally and much lip service has been paid to...

The fleet replacement problem of a profit-maximizing manager is examined using an optimal control model that captures both utilization and replacement decisions. Conditions for optimal utilization of each vessel in the fleet and optimal vessel acquisition and retirement strategies are discussed....
