Regulation,trust and contractual incentives around transport contracts – Is there anything bus operators can learn from public air service contracts?

This paper compares recent experiences in contract negotiation and subsequent commitment in public air services with the bus industry. The heart of the paper is a survey of European and Australian regional airlines, which we mirror with revealed experiences of bus operators. We aim to identify a number of elements in the contracting regimes that have exposed ambiguity and significant gaps in what the principal (e.g., transport department) expected, and what the agent (airline or bus operator) believed they were obliged to deliver. Ultimately airline and bus services are similar in that public authorities procure transport services that are desirable for the society but would be unprofitable without government involvement. In both sectors (theoretically fairly similar) public transport contracts are used, and those usually include obligations and performance measurements. In terms of similarities, one of the surveyed contract details that had a perceived high clarity in both industries was “payment procedures” and amongst those with rather poor clarity was also in both industries “incentives to improve performance and grow patronage”. We also show differences between regional air services and bus operations with regard to performance measurement and pre-specified obligations. Because of the strong safety culture around air services we find that regulation and trusting partnerships are even more important to aviation than to the bus sector. Because of the high level of trust but also because of simpler and more complete contracts in aviation, there is much less (re-)negotiation going on compared to the bus operations.     

Exchange rate changes and the cost competitiveness of international airlines: The Aviation Trade Weighted Index

Discussions of how changes in exchange rates impact on international airlines tend to be ambivalent. In this paper, it is shown that the relative cost competitiveness of an international airline will decline when there is an exchange rate appreciation in its home country - as will be the case for other tradable goods and services. The extent to which this happens depends on which countries the prices of the inputs are set in and also on which countries' airlines it is closely competing with. The impact is greater if there is an appreciation relative to those countries whose airlines the home airlines are closely competing with. In the trade literature, this is recognised in the Trade Weighted Index of exchange rates, which weights exchanges rates according to their importance in a country's trade flows. In this paper, an Airline Trade Weighted Index is developed - the weights for this index depend on airline traffic and revenues on routes to and from a country. The ATWI is calculated for Australian international airlines, and it indicates that there has been a significant loss of competitiveness in recent years, due to the appreciation of the Australian dollar relative to currencies of key airline competitor countries.     

Airline network competition: Full-service airlines, low-cost airlines and long-haul markets

The paper discusses airline network competition. Low-cost airlines and conventional airlines have distinctly different strategies and network types. This determines their ability to compete with other airlines in specific markets. The paper discusses the lack of competition between conventional airlines in local markets, and sees why low-cost airlines are the primary source of competition in such markets. Conventional airlines are relatively strong on long-haul markets, using their networks to keep costs per seat relatively low. Charter airlines show that a long-haul low-cost strategy is feasible For scheduled low-cost airlines, this may be more difficult, but this does not automatically mean that low-cost airlines cannot enter thick long-haul markets.     

The implications of the re-establishment of direct links across the Taiwan Strait on the aviation industries in Greater China

This paper investigates the economic implications of the liberalization of air transportation across the Taiwan Strait to the region's aviation industries. Our analysis suggests that (1) liberalization has brought substantial benefits to airports and airlines in Mainland China and Taiwan. Negative impacts to Hong Kong are largely compensated by traffic increase in routes linking Mainland China. (2) In general, Taiwanese airports and airlines have benefited more from liberalization compared to airports and airlines on the mainland and Hong Kong. Such asymmetric effect is due to the larger size of the Mainland Chinese aviation market, which allows Taiwanese airlines to exploit network-related benefits. (3) Our investigation suggests that foreign hub carriers and medium sized Chinese airports will benefit most from China's future liberalizations.

Will China’s airline industry survive the entry of high-speed rail?

This study investigates the effects of high-speed rail (HSR) services on Chinese airlines. Our analysis suggests that the HSR service will be competitive in terms of network connectivity, total travel time and cost efficiency. On the other hand, growth of the Chinese airline industry has been unbalanced in terms of traffic distribution, airline network development, airport capacity and share of international traffic. While the long term prospects of Chinese airlines are bright, the carriers must develop effective hub-and-spoke networks and increase their competitiveness in international markets in order to achieve sustainable growth in the coming years. For the Chinese government, continued investment at hub airports and support to low-cost carriers are also necessary.     

Design and implementation of a visual monitoring system to ensure safety in the water surrounding a container vessel

Container vessels navigate among the world's ports, frequently passing through narrow and congested waters. Due to the many layers of containers on a container vessel's decks, it is difficult for the crew to be aware of all fishing vessels and other obstacles in a container vessel's radar observation blind zone. This greatly increases the risk of collisions and other accidents. Given such great challenges to safe navigation and safety management with container vessels, their security risks are severe. An effective visual monitoring system can improve the safety of the water area surrounding container vessel by eliminating a vessel's observation blind zone, providing an effective safety measure for vessels navigating fishing zones and other troublesome areas. The system has other functions, such as accident recording, ship security, and monitoring of loading and unloading operations, thus ensuring the ship operates safely. Six months' trial operation showed that the system facilitates safe navigation of container vessels.     

Coastal Erosion in Ghana: Causes,Policies, and Management

Coastal erosion is a serious problem that affects the safety and livelihoods of many coastal dwellers along Ghana's coast. Despite the fact that coastal erosion is a natural phenomenon, erosion trends have been largely aggravated by human-induced factors. This study analyzed shoreline change rates for three neighbouring coastal communities in the Central region of Ghana; Elmina, Cape Coast and Moree. Two epochs were analyzed, 1974–2012 (medium-term) and 2005–2012 (short-term), using ArcGIS and Digital Shoreline Analysis System. Overall, the entire study area recorded average shoreline change rates of ?1.24 myear^?1 and ?0.85 myear^?1 in the medium-term and short-term period respectively. Less consolidated shoreline segments recorded higher erosion rates in both periods while cliffs and rocky segments experienced very little erosion or high stability. Because shorelines undergoing chronic erosion do not fully recover after short-term erosion events such as storms, facilities located close to such shorelines are threatened. Taking a proactive approach to coastal erosion management, such as coastal sand mining prevention, inter-sectoral land use management and adopting a construction setback approach may be prudent for the long-term management of the coast since this recognizes future shoreline changes and safeguards coastal landscape for other uses.     

A critical review of container security operations

Containers, which permit fast and safe handling between modal systems, are the main equipment used in intermodal transport. Unfortunately, enhancement of the efficiency and velocity of container operations has created a breach in traditional security, also known as container security. This paper presents a critical literature review of container security operations. We aim to identify current trends and future research directions in container security. We propose a classification framework based on the following elements: presenting the container security perspective, identifying threats, evaluating container security, balancing costs/benefits and the degree of security, balancing time savings/reduction and the degree of security, and securing containerized transportation processes. We discuss the current studies of these problems, the methodologies adopted and important insights into container security.     

Low-cost carriers in Asia: Deregulation, regional liberalization and secondary airports

While the demand for low-cost air transportation is potentially huge in Asia, development of low-cost carriers (LCCs) lags behind the region's overall aviation development, and certainly lags behind the LCC development in North America and Europe. It has been noted that market conditions and the regulatory environment of Asia are different from those of North America and Europe. What are the main differences here; and how do these differences impact market entry and success of Asian LCCs? This paper describes salient features of Asian LCCs and their developments. It examines the impact of Asia's domestic and international airline regulations and airport infrastructure on the performance of its LCCs. We find that the “Southwest effect” may also exist in Asia and that the development of low-cost terminals may compensate, at least partly, the scarcity of secondary airports in the region. The experiences of Thailand and China are investigated as case studies.     

Corporatization: a legislative framework for port inefficiencies

It is now some five years since the restructure of Australian ports and their transformation into corporatized entities. This strategy was adopted in an endeavour to improve efficiency by distancing government from day to day operations—the element that was perceived by many to be the cause of sub-optimal performance. While there is widespread agreement that port performance has improved significantly, dissatisfaction persists with the continued political intervention which is considered to be the reason for ongoing sub-optimal performance and ports' commercial potential from being realized. This paper investigates some of these issues but argues that political intervention per se should not be the focus of research and what is widely perceived to be the cause of the problem. Rather, that political intervention is an effect of something more endemic, of a legislative framework which may not be appropriate for the operations of a commercially focused port. It is argued that the focus should therefore be on the cause, a legislative framework, rather than the outworkings, or the effects of that framework.     

Incumbent responses to low-cost airline entry and exit: A spatial autoregressive panel data analysis

While the US airline industry has been substantially transformed in recent years by the growth of low-cost airlines, the cost-saving benefits of lower airfares are difficult to gauge empirically. There are two important ways in which this paper contributes to the existing literature on the impact of the low-cost carriers (LCCs). First, the availability of route-level panel data allows us to examine the role of the LCCs in the long-run adjustment of airfares as well as the responses of the incumbent carriers to LCC entry and exit in a dynamic setting. Second, we capitalize on recent developments in spatial econometrics and explicitly model the spatial dependence among adjacent airline routes, an issue often ignored by previous studies. Although most of the pro-competitive effects of LCC entry take place after entry, we find evidence that the incumbent carriers also cut airfares in anticipation of entry by the LCCs. Moreover fares remain lower even after Southwest Airlines exits. Our empirical analysis confirms the spatial dependence among airfares in adjacent routes, provides estimates of the consumer benefits from lower airfares in routes affected by LCCs, and shows that there are substantial indirect benefits, i.e. lower fares in spatially-linked, nearby routes.     

Comparing the fatality risks in United States transportation across modes and over time

This paper analyzes the transportation fatality risk in the United States. The analysis is in two parts. The first part compares the relative risks of the different modes based on data for the decade from 2000 to 2009. The second part is a time-series analysis for each mode using annual data from 1975 to 2010. By almost any measure, transportation is considerably safer now than it was in the mid 1970s. The improvement is especially noticeable for commercial modes such as aviation, railroads and maritime. Even the risks from private highway driving have halved during the past thirty-five years.

Russia's waterborne trade and transport: issues in market transformation

During the Soviet era most of the Union's international non-oil trade was transported over water. Following the former Soviet Union's break-up, the share of water transport in accomodating Russia's trade has become modest, as the railways carry most goods that are traded domestically or with the new republics of the Commonwealth of Independence States, which are now treated as foreign countries. Adjusting the Russian Federation's water transport industry and related infrastructure to the changed geo-political and regional economic conditions proves difficult. While the country inherited a fair share of the former Soviet merchant fleet, it is deprived of port assets which were originally built to serve all-Union trades but are now located in other republics of the Commonwealth of Independent States. Major reforms are required to streamline the provision of port services and the ports' commercial performance. The Russian Government took several steps in 1992 which effectively put the national water transport carriers on a commercial footing. The effect has been that many carriers chose to leave the national transport scence and engage in trades which do not include Russia. The Government is now confronted with the need to reduce dependence on foreign-owned vessels and to modernize the national merchant fleet. Difficult policy decisions have to reverse these trends so that national maritime industry asstes become more available to meet the country's needs.     

Liability for oil spill damages: Issues,methods, and examples

Liability is an important incentive‐based instrument for preventing oil spills and provides a sustainable approach for restoring coastal resources injured by spills. However, the use of liability for environmental damages raises many challenges, including quantification of money measures of damages. In this article, case studies are used to illustrate the issues, methods, and challenges associated with assessing a range of damages, from those that can be measured relatively easily using market information to more “esoteric,”; and much more difficult, cases involving non‐market‐valued losses. Also discussed are issues raised by the new national and international regulatory focus on restoration and by the simplified, compensatory formula used by some states.     

Who is safe and who is at risk: a study of 20-year-record on accident total loss in different flags

The study examines 20-years of data on 36 world principal fleets and on worldfleets in general, analyses their developments, and particularly their safety records in terms of accidental total loss rates. This study confirms that the open-registry ships tend toward substandard ships. However, some open-registry countries' safety records are quite acceptable. It finds that the safety record of developing maritime countries as a group is better than that of developed maritime countries, of which some are worse than the world average.     

Marketing management at the world's major ports

Recent technological developments in maritime transport, particularly in container shipping and larger vessels, are having major repercussions at ports the world over. The latest wave of innovations has increased the level of competition in maritime transport, in particular in port activities. Shippers have many more alternatives available, something that tends to increase the hinterland of each port, precisely by reducing captive hinterlands. Ports are now generally moving towards formulas in which private initiative has a bigger role to play. Increases in competition combined with growth in private initiatives highlight the usefulness of marketing tools in two ways. Externally, because they help to achieve throughputs from remote points of origin and destination, and internally, by aiding the proper coordination of business and organizational activity at a commercial port. The present paper is a transversal study of the current situation of marketing and quality tools at major ports, including the opinions of a range of port commercial and marketing managers. We have also tried to describe the differentiated groups to be found at ports, as a useful methodology for identifying the nearest competition or ports with similar characteristics.
