Static and changing port economic impacts

This paper attempts to provide general guidelines for conducting a port' economic impact analysis. In so doing, a methodology is proposed to organize efficiency the search for port-related industries and to determine the degree of their dependence on a port. this methodology is applied to the port of Hampton Roads. In addition, some constraints in predicting the changes in the economic impact of a port attribute to changes in the volume cargo are identified.     

The changing economic impacts of the port of New York

This paper investigates the economic effects of maritime trade through the Port of New York on the New York metropolitan region. It decomposes the impacts associated with the trans-shipment of waterborne exports and imports in 1977 and 1987 into those arising from the changing tonnage of trade and those attributable to the changing commodity mix. Input-output analysis is used to calculate the numbers of jobs, personal and business incomes, and output which arise from each effect. Finally, it examines the impacts on specfic industries and occupations in the region.     

Intraunion conflict: the changing marine engineer

In this paper we describe the shift in membership of the Marine Engineers' Beneficial Association (MEBA), the major us marine engneer labour union, and the problems asssociated with this change. The problematic nature of this change is examined by describing the changing membership of MEBA: demonstrating a relationship between the occupational socialzation of members prior to entering the union and their behaviour as members; and by explaining how the actions of MEBA led to the creation of the problem and the policy it implemented to alleviate the sitution. Data are gathared from participant observation, interviews with union officials and marine engineers. Implications for the formation of sentient groups are discussed.     

Coordination mechanisms in improving hinterland accessibility: empirical analysis in the port of Rotterdam

Hinterland accessibility is one of the main determinants in port competition. Improving hinterland accessibility is a complex process in which many actors are involved and many factors play a role. It requires coordination mechanisms beyond the price mechanism; conditions of complexity can become such that assistance is needed from other coordination mechanisms, such as introduction of incentives, creation of an interfirm alliance, changing scope, and creating collective action. The goal of this paper is to gain a better understanding on coordination in hinterland chains. Based on the insights of Transaction Cost Economics, a set of variables is explicated in order to understand when, by whom, and under which conditions and situations coordination arrangements are chosen. The variables can be divided into variables related to the complexity of the coordination problem and variables related to the coordination arrangement. The variables are used in an empirical analysis of coordination arrangements in hinterland transport from and to the port of Rotterdam. This analysis provides insight into the patterns and conditions of the emergence of different coordination arrangements that improve hinterland accessibility.     

Evaluation of foreign trade transport accessibility for Mainland China

The foreign trade transport accessibility (FTTA) of Mainland China to overseas regions is studied in terms of the shipping connectivity and achievable market scales. First, the concept of FTTA is defined. Second, the path choice behavior of shippers is analyzed, and a method to measure FTTA is proposed. Last, with 357 cities in Mainland China as the origins and eight overseas regions as the destinations, the FTTAs from origins to destinations are evaluated. The study is helpful to acquaint decision-makers with the FTTA’s spatial distribution and to offer information by which China can expand its export-oriented industry and optimize its port and shipping industries.     

Slow steaming of liner trade: its economic and environmental impacts

From 2000s, there have been three forces provoking slow steaming practice in the liner industry: (1) oversupply of shipping capacity, (2) increase of bunker price and (3) environmental pressure. This paper analyses the background and the recent application of slow steaming in liner shipping. The research looks into the questions of how slow steaming can save bunker consumption and bring benefits to the environment. On the other hand, solutions are also examined to the adverse side of slow steaming practice, i.e., how it affects the container transit time. For which, a cost model is developed to demonstrate the impact of slow steaming on the revenue change, with application to the North Europe—Far East Trade as a case study. The final result shows that the optimal speed for the shipowner is correlated with the designed speed, bunker price and the price of CO₂. With the increase of the bunker price and the price of CO_2, the optimal speed will also increase, which means that slow steaming practice has a positive impact on the environmental protection.     

Promoting social inclusion in a deregulated environment: Extending accessibility using collective taxi-based services

Bus based public transport has enjoyed revitalisation in many urban areas but outside large towns and cities its provision and quality remains erratic. Many rural settlements have infrequent services giving rise to social exclusion through transport disadvantage.The UK Government highlighted a need in Towards a Sustainable Transport System (2007) for radical new thinking on rural accessibility to help meet goals of quality of life and accessibility for all and to help meet the challenge in finding carbon friendly ways of meeting rural transport needs. This paper reports work undertaken for the Commission for Integrated Transport, an advisory body to UK Government, on how shared taxi-schemes could be developed within a deregulated environment to meet rural accessibility needs. This is based on an analysis of institutional barriers and comparison between successful mainland European schemes and UK schemes. The paper considers economic viability and the levels of subsidy currently used to provide accessibility in rural areas to show the potential for making current expenditure on rural transport in the UK ‘work harder’ to deliver a collective taxi-based service as part of the public transport mix so as to increase rural accessibility.

The changing role of ports in supply-chain management: an empirical analysis

As integrated supply-chain management (SCM) is now at the epicentre of business transformation, firms are breaking down boundaries between internal functions, as well as between the enterprise itself and key partners in the value chain (e.g. customers, distributors, suppliers and carriers). One of the main goals of such new management approach is to get everyone in the supply chain into a common platform of logistics transactions and information systems.

Against such background, the aim of this work is to analyse how and if port operators can face the challenge of higher integration, on the assumption that the higher the integration between the actors the higher the competitiveness of the whole supply chain.

Accordingly, we adopted an SCM approach in the analysis of the port of Le Havre in Renault's supply chain. More specifically, we referred to the Lambert tri-dimensional model based on supply chain's structure (actors), key business processes and links between actors. The field work—which mainly consisted of semi-structured interviews to Renault, logistics and port operators, and, finally, to the Le Havre Port Authority—was crucial to gather the needed information.     

Changing accessibility, dwelling price and the spatial distribution of socio-economic activities

In this paper we present an activities-location choice model with endogenous price which simulates, based on Expected Random Utility principle, the behaviour of several agents of the urban system (e.g. the workers distinguished by income, the firms by economic sector) to estimate the spatial distribution of socio-economic activities within the study area as well as the impact of differential changes in accessibility on the dwelling price. The study area for this research is the metropolitan area of Napoli (South Italy), for which we show the results of the model estimation and the results of a “backcasting” analysis.     

The impacts of maritime piracy on global economic development: the case of Somalia

This paper investigates the impacts of maritime piracy on global economic development. Calibrated with data between 2003 and 2008, we model shipping demands and competition in the Far East-Europe container liner shipping service and investigate the economic welfare loss effects due to reduced volumes of trade and shipping, as well as efficiency loss due to geographical re-routing of shipping networks which would be otherwise uneconomical. The substantial economic loss simulated from our model indicates that, even from purely the perspective of economic interests, more efforts from the international community should be dedicated to tackle maritime piracy.     

Longhaul feeder services in an era of changing technology: an Asia-Pacific perspective

Traditional liner carriers, operating in the highly competitive commercial environment of the last few years, have attempted to lower the marginal cost of each box carried. Technological improvements in both construction and propulsion systems have led to a steady growth in carrying capacity. Ships of 600+ TEUs are now in service and, as a result of this trend, have displaced 'smaller' ships from the major east-west trades. The more competitive environment of these trades has in turn led to a redeployment of ships in the 2500+ TEU range to the north-south trades. The result has been a rapid increase in north-south capacity, including feeder services and falling freight rates. Despite the current excess supply in shipping and historically low freight rates, significant developments in technology have created opportunities for new fast containerships. The paper analyses the key economic factors in the differentiation of the new fast ship technology from the traditionally designed containerships and demonstrates the potential financial viability to owners of these new 'greyhounds'.     

Bus Rapid Transit implementation in Beijing: An evaluation of performance and impacts

Bus Rapid Transit (BRT) systems are undergoing rapid development in many countries due to the unique characteristics of this form of mass transit. In China, BRT schemes are being adopted as a key strategy for relieving traffic problems. As a case-study, this paper examines the performance and impacts of BRT in Beijing, the first full-featured BRT system in China. It considers in turn the role of ITS technology in influencing the operational efficiency, technical performance and cost issues associated with BRT. Particular attention is given to the consequent impacts of BRT on travel behaviour change, traffic environment and property development. While some challenges remain, the early performance of BRT suggests that it is one of the key measures for promoting sustainable mobility.     

The impacts of mass transit on land development in China: The case of Beijing

Land development impacts of mass transit have long been studied in the developed economies. Yet relatively little is known by the outside world about the Chinese experience due to China's rather short history in the development of modern mass transit and land/property market. This paper attempts to fill the gap by presenting evidence from China, with a detailed case study of Beijing. Selecting three newly built suburban transit lines in Beijing, the study examined land development context and estimated hedonic housing price models to measure the proximity premiums associated with these three lines. The empirical evidence in Beijing, one of the first tier mass transit cities in China, shows that investments in mass transit can have significant and positive impacts on land development. Properties with transit proximity enjoy sizable price or value premiums. The study also confirms the international experience: transit impacts on land development are unlikely to occur automatically; they rely greatly on supportive regional and site conditions. Integrated planning and design for mass transit and land development are critical to expand and maximize the return of transit investments.     

Evaluating the long term impacts of transport policy: An initial assessment of bus deregulation

Local buses in Britain, outside London, were ‘deregulated’ as a result of the 1985 Transport Act, with most of the organisational changes implemented in 1986 but many of the ownership changes occurring over a longer period. By contrast, in London, the 1984 London Regional Transport Act introduced a system of comprehensive tendering – but it took 10 years for the organisational and ownership changes to be fully implemented. This paper examines the long term impacts of these changes. A key issue when examining long term changes is that of the counterfactual – what would have happened if the changes had not occurred? An econometric model of the demand for local bus services in Britain is outlined and used in conjunction with extrapolative methods for key variables such as fares and bus kms to determine demand-side counterfactuals. Some analyses of subsidy and of costs will also be outlined. This will then permit the examination of welfare change by estimating changes in consumer and producer surpluses, updating earlier studies. It is found that outside London, bus demand declined strongly, at least up to the year 2000 and some of this reduction can be ascribed to deregulation. By contrast in London, demand has generally been increasing. However, in both areas operating costs also declined strongly, again up to 2000, but since then there have been strong increases in costs and subsidy. Our initial finding is that there are net welfare increases both outside and inside London, but with welfare increases per capita being five times greater in London than elsewhere. However, sensitivity analysis shows that our results are sensitive to the specification of the modelling system and assumptions made concerning the counterfactual, particularly for the results for London.     

Evaluating the long term impacts of transport policy: The case of passenger rail privatisation

Britain's national rail system was ‘privatised’ as a result of the 1993 Railways Act, with most of the organisational and ownership changes implemented by 1997. This paper examines the long term impacts of these changes. A key issue when examining long term changes is that of the counterfactual – what would have happened if the changes had not occurred? A simple econometric model of the demand for passenger rail services was developed and used in conjunction with extrapolative methods for key variables such as fares and train km to determine demand-side counterfactuals. Extrapolative methods were also used to determine counterfactual infrastructure and train operation costs. Although our results are sensitive to the assumptions we have made concerning the counterfactual they suggest a number of impacts. Since privatisation, rail demand has grown strongly but our analysis indicates that transitional disruptions suppressed demand by around 9% over a prolonged period (1992/3 to 2005/6), whilst the Hatfield accident reduced demand by about 5%, albeit over a shorter period (2000/1 to 2006/7). A welfare analysis suggests that although consumers seem to have gained as a result of privatisation, for most years this has been offset by increases in costs. An exception is provided by the two years immediately before the Hatfield accident. Overall the loss in welfare since the reforms were introduced far exceeds the net receipts from the sale of rail businesses. Thus although the reforms have had advantages in terms of lower fares and better service levels than otherwise would have been the case, this appears to have been offset by increased infrastructure and train operations costs. The source of these high costs remains an area of speculation but appear to be related to aspects of both market and regulatory failure.
