Benchmarking the noise-oriented efficiency of major European airports: A directional distance function approach

The EU Environmental Noise Directive (END) requires member states to produce noise action plans for all major airports every five years. Using that data, this paper employs a directional distance function approach to estimate noise-oriented efficiency of 60 European airports between 2006 and 2011. Technical change is calculated using the Malmquist productivity index. The results indicate that European airports have improved their noise efficiency between 2006 and 2011, and some degree of convergence in noise performance across countries is seen. Larger aircraft size is linked to better noise performance. Inefficient airports would also benefit from more stringent night movement limits.     

A comparative efficiency analysis of Spanish and Turkish airports

AENA in Spain and DHMI in Turkey operate a large majority of the airports in their respective countries. These two airport operators share some similar characteristics, but also present many differences with respect to their management strategies. For instance, the Turkish DHMI introduced a Build-Operate-Transfer (BOT) model and concession agreements, which enables active private participation in airport management. In contrast, management and operation responsibilities at all airports in Spain –with a few exceptions-have remained with AENA. This paper utilizes a data envelopment analysis (DEA) to compare the relative efficiency of airports within AENA and DHMI for the years between 2009 and 2011. Based on the efficiency scores, it further identifies the sources of inefficiencies resulting from various management strategies and other external factors. The results indicate higher average efficiency levels at Spanish airports, but private involvement enhances efficiency at Turkish airports. The majority of the airports in Spain and Turkey operate under increasing returns to scale. Certain policy options, including a higher private involvement and improvement of the airport network by closing some inefficient airports, should be considered in order to increase the airport efficiency in both countries.     

Spanish airports performance and efficiency benchmark. A PESA-AGB study

This study uses a MCDA tool to analyse and improve Spanish airports performance and efficiency. Thus, a holistic study using MACBETH (with PESA-AGB) is used. This study has never been applied before in Spanish airports. Firstly, a literature review related to this study keywords is conducted, as well as about benchmarking concept applied specifically to airports. Secondly, several methodologies in used to benchmark airports are reviewed and compared. Thirdly, airport performance and efficiency issues are addressed and described. Finally, the MCDA-MACBETH (with PESA-AGB) tool is applied to 4 Spanish airports.Spanish airports belonging to AENA transported 263, 753, 406 passengers in 2018 with an increase compared to 2017 of 5.8%. General data enables to conclude that.Spanish air transportation system is growing annually and hence there is the need to improve airports performance and efficiency, also to maintain the high levels of quality to address the growing demand. Spanish air transportation system is growing annually and is it upmost important to maintain high levels of quality to address such demand. Through this study, performance and efficiency improvements are seek within several airport key areas such as Safety and Security, Quality Service, Productivity and Effectiveness, Financial and Environment.     

Comparative analysis of efficiency for major Southeast Asia airports: A two-stage approach

Within the past few years, the economy of Southeast Asia has been expanding rapidly with the rise in demand for air transport services. International airports are important driving forces for Southeast Asia countries' economies. Therefore, the competitive ability of these airports is very essential in terms of development and competitiveness within the region. This paper investigates the capabilities of these airports by a two-stage approach. The strengths and weaknesses of each Southeast Asia airport are evaluated by Data Envelopment Analysis – Slack-Based Measurement (DEA-SBM) in the first stage. This is a non-parametric approach to measure the efficiency of 9 major airports in the area including Changi Airport (Singapore), Suvarnabhumi Airport (Thailand), Kuala Lumpur Airport (Malaysia), Soekarno Hatta Airport (Indonesia), Ninoy Aquino Airport (the Philippines), Noi Bai Airport, Tan Son Nhat Airport (Vietnam) and Guangzhou Baiyun Airport (China), Hong Kong Airport (Hong Kong). In the second stage, Tobit regression is used to estimate the influence of multiple factors toward the efficiency of each airport. By generalizing and comparing two stages, the analysis allows us to evaluate each airport's efficiency in seven years, as well as the impact of multiple factors in one airport's performance. The implications for improvement are also obtained and discussed.     

Are outsourcing and non-aeronautical revenues important drivers in the efficiency of Spanish airports?

This paper evaluates the influence of contracting out, or outsourcing, certain airport services and of commercial diversification strategy. Although most of the effort is being put towards applying non-parametric techniques in airport efficiency studies, we have chosen parametric methodology. We use a distance function, as it has known advantages. The findings show the positive contribution of outsourcing and non-aeronautical revenues on the efficiency of the Spanish airports' network.     

Sustainable efficiency drivers in Eurasian airports: Fuzzy NDEA approach based on Shannon's entropy

This research explores the physical infrastructure and flight consolidation efficiency drivers of Eurasian airports regarding their infrastructure and movement productivity levels. A novel Fuzzy Double-Frontier Network DEA (FDFNDEA) model is proposed to investigate the relationship between desirable (freight and passenger turnovers) and undesirable (pollutant emission levels due to aircraft movements) outputs against the respective infrastructure usage, fuel consumed, and movements performed at each of the 23 Eurasian airports from 2000 to 2018. This balance between desirable and undesirable outputs emerges spatially and temporally due to the evolution of the airport system's productive resources at each one of the Eurasian countries over the period observed. Shannon's entropy is used as the cornerstone to quantify the input and output vagueness of this evolution in Triangular Fuzzy Numbers (TFN), thus allowing the accurate building of alternative optimistic and pessimistic double-frontier efficiency. Differently from previous research, Shannon's entropy is the key for measuring input and output vagueness levels in light of the maximal entropy principle. This principle states that the distribution that best represents the current state of knowledge is the one with largest entropy. Maximal entropy yields bias-free decision-making in the sense that the input/output distributional profiles for Eurasian airports contain the maximal possible heterogeneity, working as a robust or best/worst-case scenario against eventual unconsidered assumptions. Hence, optimistic and pessimistic Malmquist Productivity Indexes (MPI) for overall and each stage productivity results are subsequently regressed against contextual variables related to airport characteristics and regional socio-demographic and economic indicators of each Eurasian country using bootstrapped Cauchy regressions. The findings revealed the spatial heterogeneity of productivity factors and airport performance across Eurasia. Results also demonstrated the negative impact of income inequality and the positive impact of private participation on technological progression in the Eurasian airport industry.     

Multi-period efficiency and productivity changes in US domestic airlines

This study tracked the static efficiency and dynamic productivity changes of 14 US airlines from 2006 to 2015. Moreover, we estimated the principal economic drivers of the environmental variables to increase the US domestic airlines' efficiency using the double bootstrap regression analysis. The major aspects of this study are as follows: First, network legacy carriers have the highest efficiency, whereas low-cost carriers are lowest. Nonetheless, network legacy carriers still have room to improve scale inefficiency. Second, the fluctuations in technical change, rather than in efficiency change, tended to have greater effect on the fluctuation of Malmquist productivity index for US domestic airlines. Third, M&A between US airlines have both positive and negative effects in terms of efficiency and economies of scale. Fourth, cost environmental factors have a negative effect on US airlines' efficiency, while revenue factor is a positive effect. The results of this study may help US airline industry practitioners to understand the US domestic airline environment from an operator's perspective.     

A dynamic network efficiency measurement of airports performance considering sustainable development concept: A fuzzy dynamic network-DEA approach

In this paper, sustainability of airports is considered through a multi-perspective, multi-system, and multi-process operation. It is explored how an extension of fuzzy dynamic network performance measurement approach helps to determine the efficiency performance of an airport system. In this way, a three-pronged approach is intended which considers the internal functions of an airport, functions affecting the community and functions related to the passengers simultaneously. This novel combination makes it possible to have a comprehensive evaluation of airports' performance. Besides, fuzzy extension of SBM dynamic network approach makes it possible to deal better with the vagueness of variables during analysis. So, this extension is valuable from both technical and conceptual aspects which in turn provide useful information and insights for the future design of holistic strategies connected with sustainable development of airports where ever they are.     

The geographical efficiency of Spain's regional airports: A quantitative analysis

Previous studies of the role of regional airports in the Spanish economy have focused on calculating efficiency using air traffic as the output and airport infrastructure data as the input. We present an alternative quantitative analysis based upon the geographical structure within the airport's market basin. We formulate a ‘geographical efficiency’ model that considers territorial variables within the airport hinterland. Input data for our model include the socio-economic structure of the population, intermodal transport links, industrial and tourism potential and existing leisure-related services. The output is the annual number of passengers associated with such constraints. The result is a relative efficiency estimate that shows uneven patterns of geographical efficiency amongst Spain's regional airports and also provides insights into opportunities for expanding some of these critical items of infrastructure. They suggest that some of Spain's regional airports may be better placed than others to compete in a liberalized market that exhibits a clear tendency in favor of coastal, tourism-based airports.     

Evaluating the multi-period operating efficiency of international airports using data envelopment analysis and the Malmquist productivity index

For the most part, airports are publicly or semi-publicly owned and operated with fixed assets. As such, airports have been often considered little more than infrastructure providers for airlines. However, as airports have begun to offer a variety of ancillary services including passenger transfers, re-fueling, parking, and shopping, they no longer play second fiddle to airlines. To come into their own, a growing number of airports realized their need to develop competitive strategies that can attract more air traffic and generate greater revenue. Such strategies start with the assessment of their competitiveness in terms of operating efficiencies relative to others. To help airport authorities identify major drivers for enhancing the airport operational efficiency and the subsequent competitiveness, this paper evaluates the comparative efficiencies of international airports for a multi-year period (2006–2011) using data envelopment analysis intended for dynamic benchmarking and Malmquist productivity index built on time-series analysis. Our study indicates that the productivity of an airport was influenced by exogenous factors such as shifts in government policies and technological advances rather than endogenous factors driven by improvements in managerial practices.     

Spatial distribution characteristic of Chinese airports: A spatial cost function approach

This paper uses spatial econometric models to analyze the spatial distribution of Chinese airports from 2002 to 2012, taking into consideration the factors that explain the distribution of airports around the country. A cost function allowing for latitude and longitude is estimated based on spatial location, which leads us to advise the implementation of policies that take into account the spatial distribution of the airports. Results show that the development of airports in China needs to consider the spatial relationship among the many different regions of China. To improve the cost efficiency, airports should be located in more economically developed areas. Meanwhile, it also helps to reduce the cost when listing on the stock market.     

Runway safety at airports: A systematic approach for implementing ultra-safe options

Enhancing airport runway safety is a difficult problem because runway accidents are rare events. Nonetheless, investments are being directed at improving safety for US airport ground traffic control systems. This paper shows that under these circumstances it is difficult to assess and measure the added safety offered by new replacement systems. We develop a framework for introducing and sequencing system improvements to provide greater assurances in enhancing safety. This framework shows how a new method can first be introduced as a secondary system, to test and verify its efficacy prior to its adoption as a primary system.     

Airport pricing systems in europe and an application of Ramsey pricing to Spanish airports

This paper describes the landing fee structures which are prevalent at most European airports: a mix of weight-based landing fees, passenger fees, and other charges. The paper describes alternative pricing systems which emphasize economic efficiency rather than airport finance considerations. Finally the paper calculates the structure of landing fees for a hypothetical uncongested airport using a Ramsey pricing formulation with data representative of uncongested Spanish airports. Further research is necessary before recommending implementation because the elasticities of demand and operating costs with distance are borrowed from North American studies.     

Airport quality and productivity changes: A Malmquist index decomposition assessment

This paper analyses the productivity of 20 Italian airports management companies during the period 2006–2008 using a DEA Malmquist index that includes a quality component. The proposed methodology is applied for the first time to the airport industry. In doing so, we directly assess the impact of the quality of services delivered by an airport on its productive performance. The study shows that, while Italian airports possess an acceptable level of quality in terms of their infrastructure, their managerial/administrative procedures must be strengthened in order to better deal with both technological modernization and passenger waiting time at the airports.     

Four decades of airline productivity and efficiency studies: A review and bibliometric analysis

Airline productivity and efficiency have remained an area of tremendous interest among both academics and industry analysts since the Airline Deregulation Act of 1978 was enacted in the United States. This paper provides a bibliometric analysis of airline productivity and efficiency studies during the period from 1979 to 2020. The results show that the Journal of Air Transport Management, Transportation Research Part A, and Transportation Research Part E were the top three outlets preferred for publications in this area during the study period, and productive authors were likely to produce influential works. Research interest in airline productivity and efficiency has spread to encompass more diversified geographical regions over time, and new researchers from a broad range of fields continue to become interested in this field of research. Data envelopment analysis and stochastic frontier analysis are shown to be the most popular methods used by researchers, and studies are increasingly attempting to incorporate undesirable outputs, such as carbon emissions, flight delays and accidents, into the measurement and analysis of airline performance. The results from this study can provide guidance for future research issues and directions.     

Keeping cargo security costs down: A risk-based approach to air cargo airport security in small and medium airports

European Union regulations are not sensible to the proportionality of measures and provide fixed orientations and standards irrespective from the dimension of the airports. Additional security measures have been added over the years resulting in increasing security-related costs. The cost structure of security exhibits the existence of a relevant fixed component, concerning staff, equipment, or certification. Notable, smaller, and medium airports support higher costs of security than larger airports, due to the low volumes of cargo and passenger movements. Alternative approaches, notably risk based, have been advocated to support the definition of security procedures at airport level. Although studies have been conducted, none was found concerning these types of airports.This paper presents a research aimed to analyse the appropriateness of a risk based approach in the context of small to medium airports. The research focused in understanding whether such approach could provide tailored security requirements and, ideally, lower costs.A case study considering six airports - Horta, Lisbon, and Ponta Delgada (Portugal), and Adana Şakirpaşa, Erkilet International and Istanbul (Turkey) - of different sizes and located in different regions was conducted. The results make evident the advantages of a risk based approach to define appropriate security procedures, although it is not evident that a risk based approach will lower costs.     

Strategies and pitfalls in the infrastructure development of airports: A comparison of Milan Malpensa and Berlin Brandenburg International airports

The paper analyses two airport investment projects in Europe: the completed investment at Milan Malpensa Airport and the investment at Berlin Brandenburg International. The two facilities were chosen because of similarities in their market environments. The paper examines the history of the projects, their objectives, demand forecasts, assessment methodologies and the strategies of the main carriers that use them. A comparison between expectations and outcomes for Malpensa a decade after its opening allows examination of the validity of the parameters used in the decision-making. The criteria being used to assess the investment in Berlin Brandenburg International are explored.     

Evaluating impacts of institutional reforms on port efficiency changes: Ownership,corporate structure,and total factor productivity changes of world container ports

This paper evaluates how port institutional reforms influenced efficiency gains between 1991 and 2004. We constructed a panel data for port ownership, corporate structure, and port inputs and outputs for 98 major world ports, and we implemented the Malmquist Productivity Index (MPI) model. The MPI provides efficiency measures for input combinations that allow for obtaining the outputs in the presence of institutional reforms, ownership changes, main agent problems, technological progress, efficient scale growth, and many other reasons for efficiency and the lack of it. The results illustrate that ownership restructuring contributed to total factor productivity gains. The restructuring induced optimized operation of container terminals, especially for large ports, as it allowed specialized private entities to concentrate on terminal operation and cargo handling services.     

Accessibility and attractiveness of European airports: A simple small community perspective

This paper describes a simple method for comparing airports based on their accessibility to regional, continental or global air transport networks, using a variety of different measures of traffic. The method is applied to all Irish and UK airports for the years 2000, 2003 and 2005 and compares the performance of these airports in serving the UK/Ireland, Western European, Greater European, North American and global air transport markets. The method may be generalised to assess other regional groupings of airports in differing regional contexts, in situations where very limited demographic and socio-economic data are available.     

Substitution and complementarity in aviation: airports vs airlines

In this paper a model concerning substitution and complementarity on the linkage between airport facilities and airlines from the viewpoint of pricing policy is formulated. This model is used to analyze whether airport pricing policies, e.g. to ensure cost recovery, are compatible with competition for transfer passengers. It is found that airports with a high volume of demand can pursue cost recovery and still be the most preferred hub. Airports with a low level of demand will not be the preferred hub, even if the larger airport charges higher taxes to recover costs.
