EU involvement in TEN development: network effects and European value added

The recent White Paper emphasises once more that the Trans-European transport network (TEN) is a key element in European Union (EU) policy, yet that its realisation is jeopardised by the lack of an integrated approach during evaluation and funding of cross-border infrastructure. Despite the intervention of the EU in conceptualising the TEN, subsidiarity and continued use of conventional evaluation procedures mean that most assessment of individual TEN components is still undertaken in relatively narrow, national terms. The primary objective of this paper is to explore how the international character of the TEN may be recognised and incorporated in still predominantly national evaluation processes, and which evaluation horizons may be broadened based on the concepts of network effects and European value added (EVA). We present some examples of EVA and discuss EU involvement in projects with potentially high EVA, either by co-ordinating bilateral negotiations for compensation between Member States or by co-financing projects that support the achievement of strategic EU transport policy objectives.     

Strait crossings and economic development: Developing economic impact assessment by means of ex post analyses

There is widespread scepticism among politicians and authorities concerning CBA as a main instrument for decision-making. This may cause possible bias towards non-quantitative factors as decisive. The challenge is to improve the methological approach, carefully examining the real benefits for road users. One way of doing this is to develop ex post CBA to test how critical assumptions fit to reality. The focus of this paper is on ex post analyses carried out with five case studies in larger infrastructure projects to assess the economic profitability actually occurring from new infrastructure. There are substantial differences in benefits ex post compared with the ex ante analyses, mainly explained by a shift parameter in willingness to pay (WTP) for the improvements. These ‘inconvenience costs’ saved by the road users add to the traditional value-of-time benefits. The paper also examines the profitability of private versus public funding and ends up with some considerations on regional impacts of transport infrastructure. A short presentation of a pilot study from two of the fixed links to elicit the influence on local industry is given. Some informal results support the theory of forward and backward linkages from new economic geography.     

Measuring the substitution effects between High Speed Rail and air transport in Spain

The main objective of this paper is to estimate the impact that the expansion of the HSR network has had on air transport in Spain by estimating the substitution effect between the two types of transportation. This paper considers the way that the HSR network has grown and how this growth could have affected air transport dynamically. The findings show that a dynamic vision of this substitution rate should be adopted, as opposed to assuming that the rate is constant, as has been the case in previous references. Although the rate varies significantly over the study period, only 13.9% of HSR passenger demand was found to have come from air travel during the 1999–2012 period, meaning that HSR and airlines would seem to offer more independent services than at first it might appear. This confirms the hypothesis as to the HSR’s great ability to generate its own demand. The substitution rate between the two transport modes seems to be closely linked to the way that any new stations are incorporated into the HSR network. Convergence between the seasonality of HSR and air transport has also been examined. The results show that it is difficult to talk of a real HSR transport network in Spain.

Short-term Perturbations and Tourism Effects: The Case of SARS in China

The 2003 SARS epidemic created a significant negative impact on tourism development in China. This paper reviews the effects on tourism of different short-term crises, analyses the effects of SARS and explores the possibility of tourism businesses being buffered from such short-term crisis and the possible new motivations derived from the crisis. Tourism’s lack of resistance but high resilience to short term crises provides tourism and regional planning challenges. These characteristics suggest diversification and partnerships can minimise community vulnerability to crises and rapid economic recovery is possible based on tourism’s resilient nature.     

Regional labour markets and job accessibility in City Network systems in Germany

Spatial labour markets are subjected to the forces of regional economic activity and competing network effects. Commuting is, therefore, an important equilibrating vehicle in a City Network constellation. Cities act as attractors of commuters, as most economic activity occurs in cities, thus providing a high share of attractive workplaces. Cities that are centrally connected in a network may act as both centripetal and centrifugal forces in the whole system. The present paper focuses on what is named the City Network (CN) approach. A central idea is the accessibility concept, which is interpreted here as the potential of opportunity for interaction, which has a positive impact on economic growth. In our paper, the accessibility concept and the CN concept are linked together by positioning accessibility in the CN system. Since accessibility measures give geographical insights into the distribution of economic activities and the related (dis)equilibrium of regional development patterns, the connection with the labour market is evident, and, therefore, a second focus of our analysis.In an applied setting, our paper aims to investigate spatial accessibility patterns in the main CN in Germany. The 17 districts which belong to the country’s CN were chosen from the 439 German labour market districts on the basis of three criteria: (a) their connection to the high speed railway network; (b) the most accessible districts according to previous results (2002); (c) relevant districts for the German economy. Our applied modelling research concerns home-to-work commuters travelling between the selected districts belonging to the German CN, for both 2003 and 2007. Here, a comparative analysis of the ranking of the most accessible districts - also for different intra-zonal travel times - is carried out in order to map out the changes in accessibility between 2003 and 2007, especially in the light of new high speed connections and commuting flow dynamics.     

Cooperatives for fruits and vegetables in emerging countries: Rationalization and impact of decentralization

We develop a (noncooperative) game theoretic model for a decentralized setting wherein fringe farmers compete with a two-tier cooperative network involving network farmers and a coordinator. We examine the roles of the coordinator and profit sharing in allocating costs/benefits of externalities in enhancing network efficiency and stability. Our main finding is that using profit sharing based mechanism the coordinator can overcome inherent inefficiency and instability of decentralization and noncooperative behavior of the network farmers. The roles of the coordinator and profit sharing are particularly important when it is economical for both network and fringe farmers to supply the product.     

The impacts of high-speed trains on British economic geography: a study of the UK’s InterCity 125/225 and its effects

The arrival of high-speed trains (HSTs) leads to unprecedented time-space effects, potentially assisting face-to-face contacts in knowledge-generating process, yet its wider spatial-economic impacts are still open to debate. This research attempts to fill in this gap with empirical evidence by studying the inter-regional impacts of upgraded British InterCity 125/225 on British economic geography over 30 years. The six study routes of London-outbound trains serving major railways stations in 26 local authorities were selected as units of analysis, with the observation of differential effects both between HSTs and non-HSTs towns and among each group of towns, to understand time-space effects of InterCity 125/225 whose potential impacts on local economic strength and knowledge intensive development. The key findings suggest that the differential HST effects on British economic geography could be classified into three influential zones, namely 1-h, 2-h, and over-2-h towns. HST has had substantial and demonstrable effects in aiding this transition within a 2-h travel limit of London, thus helping to generate renewed economic growth, but that the effects have not been automatic or universal. Regarding future British HST policy, the implications arising from this study is that cities connected to a new HST could seize opportunities which non-HST cities will not be able to do so, but this is not a zero-sum situation. Instead, it involves a national strategy to develop a hierarchical network with HST between London and key regional hubs, well integrated at these hubs with intra-regional transport systems. This indicates a strong case for a finer-grained and deeper probing analysis at an intra-regional level of the potential for rail improvement as an agent of change in city-region development. We hope to report further on this in a subsequent paper.

The spatial impact of EU Pan-European transport axes: City clusters formation in the Balkan area and developmental perspectives

This article explores the spatial and development implications of the Pan-European Transport Axes in the Balkans. For that purpose, the potential Development Poles and Axes are determined, on the basis of size, the location of cities, their interconnection and their role as hubs of the Pan-European axes. This is achieved by means of the formation and implementation of a methodology based on the use of special statistical applications. According to data analysis, three geographical units arise: Central Core, Peripheral Zone, Perimetric Zones. In the analysis that follows, Advantages, Weaknesses, Opportunities and Threats are examined in each case and suggestions are made as regards the policies required.

Redistributive effects of bus rapid transit (BRT) on development patterns and property values in Seoul, Korea

This study investigates the redistributive effects of Seoul's bus rapid transit (BRT) system on development patterns and property values using an urban simulation model. The Seoul Metropolitan Integrated Urban Model (SMIUM) combines the Seoul metropolitan input-output model with random utility-based location choice models and endogenous real estate markets.The major findings of this study can be highlighted as follows. First, Seoul's BRT contributes to increased development density in urban centers, acting as a centripetal force to attract firms from the suburbs into urban cores and supporting arguments for Smart Growth proponents. Second, unlike its redistributive effects on nonresidential activities, the BRT has a limited effect on the redistribution of residential activities, implying that residential locations are less sensitive to accessibility improvements made by the BRT than are nonresidential locations. Third, reflecting the transferred space demands from the suburbs to the urban cores, the CBD reaps the highest property value gains, while all of the outer ring zones suffer from reduced property values.
