Modelling regional accessibility to airports using discrete choice models: An application to a system of regional airports

In this paper, we analyse residents' decisions regarding airport access mode in Apulia, a relatively peripheral multi-airport region in Italy. Both revealed and stated preferences data are used to estimate probabilistic demand models. The results are employed to calculate the relevant elasticities, separately for airport users and non-users, with respect to dedicated existing and planned/potential public transport services. We measure the effectiveness of specific policies/actions aimed at generating a shift from private modes (car and taxi) towards public transport, rationalising mobility towards the existing airports. Accessibility is one of the key factors in airports' provision, and an efficient public transport system might represent both an alternative to opening “local” – often costly and inefficient – airports in the same catchment area and a means to exploit economies of scale aggregating demand for existing airports

Allowing for Heterogeneity in the Consideration of Airport Access Modes: The Case of Bari Airport

Mode choice models traditionally assume that all objectively available alternatives are considered. This might not always be a reasonable assumption, even when the number of alternatives is limited. Consideration of alternatives, like many other aspects of the decision-making process, cannot be observed by the analyst, and can only be imperfectly measured. As part of a stated choice survey aimed at unveiling air passengers’ preferences for access modes to Bari International Airport in Italy, we collected a wide set of indicators that either directly or indirectly measure respondents’ consideration of the public transport alternatives. In our access mode choice model, consideration of public transport services was treated as a latent variable, and entered the utility function for this mode through a “discounting” factor. The proposed integrated choice and latent variable approach allows the analyst not only to overcome potential endogeneity and measurement error issues associated with the indicators, but also makes the model suitable for forecasting. As a result of accounting for consideration effects, we observed an improvement in fit that also held in a validation sample; moreover, the effects of policy changes aimed at improving the modal share of public transport were considerably reduced

A taste of the sea: artisanal fishing communities in the Philippines

The Philippines remains one of the top suppliers of seafarers to the global merchant fleet. In the 2015 BIMCO Manpower Report on seafarer supply countries, the Philippines ranked first for ratings and second for officers with 363,832 Filipino seafarers deployed to ocean-going merchant vessels in 2014 and accounting for 28% of the global supply of seafarers (MARINA 2015). Seafarers are crucial in keeping the Philippine economy afloat and in 2018, Filipino seafarers sent home USD 6.14 billion (Hellenic Shipping News 2019), accounting for about a fifth of the USD 32.2 billion overseas workers sent home that year (Inquirer 2019). The Philippines has developed as a major player in the crewing sector of the global maritime industry primarily because of its maritime history (Giraldez 2015; Mercene 2007; Schurz 1939), its maritime geography and the continued centrality of the sea to many people’s lives (as attested to by the presence of the myriad fishing communities dotted around the many islands of the country) (Warren 2003, 2007), the economic liberalisation of the 1970s and the concomitant institutionalisation of the labour export policies as enacted by Philippine governments since the presidency of Ferdinand Marcos whose latter policy saw many Filipinos seeking employment overseas (Asis 2017; Kaur 2016; Wozniak 2015)

Impact of Port Investment on Efficiency and Capacity to Attract Traffic in Spain: Bilbao versus Valencia

The growth in intermodal transport has led to an increase in competition between ports. Other factors, such as the globalisation of the economy, European Union interest in integrating the port system into the Transeuropean Transport Network and the reform of the Spanish port system, have encouraged the Spanish Port Authorities to develop competitive strategies to extend their hinterlands. These strategies have often focused on improving port infrastructure in order to improve the efficiency of their services. In this paper, we analyse the extent to which investment expenditure has led to improvements in efficiency and how far this improved efficiency has increased the port's ability to attract traffic. To do so, we use DEA and study inter-port traffic redistribution from the land side. The analysis focused on the Ports of Bilbao and Valencia not only because they are very important in the Spanish port system but also because they both stand out for their investment expenditure, which has led to quite different results. We conclude by discussing the consequences of investment and port location for efficiency and the capacity to attract traffic, respectively.
