The impact of environmental variables on the efficiency of Chinese and other non-Chinese airlines

This paper explores the impact of an international focus, the proportion of cargo traffic, and the level of salaries on the operational efficiency of Chinese airlines and other non-Chinese airlines. Data envelopment analysis (DEA) is employed to evaluate the operational efficiency and a bootstrapped truncated regression is applied to explore the impact of environmental variables on efficiency. The results show that an international focus has a negative impact, while the level of salaries has a positive impact. Also, we demonstrate that there is an inverted U-shaped relationship between efficiency and the proportion of cargo traffic.     

Japanese-airport benchmarking with the DEA and endogenous-weight TFP methods: testing the criticism of overinvestment in Japanese regional airports

As aviation demand increased constantly along with the rapid economic growth in Japan and surrounding East Asian countries over the last several decades, Japanese government promoted airport construction since 1950s. However, the recent change in the economic background has made rise to a criticism toward the inefficient public investment, especially the transportation infrastructure. In this criticism, it has been argued that some of the small regional airports are indeed suffering the issue of overinvestment. Thus this paper attempts to verify the validity of such criticism by statistically measuring the efficiency of Japanese airports and conducting comparative analysis. For this objective, the paper employs two distinct methods namely data-envelopment analysis and endogenous-weight TFP methods. The results from these methods consistently indicates that the efficiency of regional airports in mainland Japan are lower than others, and that those airports constructed in the 1990s are relatively inefficient.     

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.
