Crisis Management—

SUMMARY

This paper reviews the crisis preparedness of the Greek passenger shipping industry after two widely publicized crises events (Superfast III and Express Samina). As far as Greece is concerned, the travel and tourism industry is one of the most significant contributors to the country's GDP at a rate of more than 10% and the country's passenger shipping industry contributes fundamentally to this figure. Overall findings suggest that both the State as well as the passenger shipping companies encompass crisis management tools and mechanisms to protect the industry, and the whole Greek tourism sector. This paper also identifies the 'ripple effect,' the wider implications a crisis can have on the business environment. Therefore the Faulkner (2001a,b) model for tourism disaster management framework is adapted to accommodate permanent changes enforced on the whole industry as an outcome of a crisis situation.     

Exploring cruise ship passenger spending patterns in two Uruguayan ports of call

The cruise industry has become a significant component of the Uruguayan tourism economy in the last few years. The present study aims to provide a better understanding of the cruise industry by considering the expenditure of cruise ship passengers disembarking at the ports of call of Montevideo and Punta del Este as a key variable in the economic analysis of the costs and benefits. We estimate two cross-sectional regression models for cruise passenger expenditures, and show that the size of the group the visitors travel with and visitor mobility within the country are the most important variables to explain individual expenditure behaviour. We also include some management recommendations that policy-makers could implement in order to improve the economic profits from cruise ship tourism.

Frequency and aircraft size dynamics in a concentrated growth market: The case of the Chinese domestic market

Despite the explosive growth of the Chinese aviation sector and the major industry reforms undertaken in recent decades, the Chinese domestic market remains highly concentrated with a significant element of regulation and governmental control in areas such as market entry and airline fleet planning. In this study, we investigate the frequency strategies and aircraft choices of airlines operating in this concentrated growth market. Our empirical investigation suggests that airlines mainly accommodate rapid traffic growth by flying more frequently, although increased aircraft size also contributes to market expansion. We also find a negative relationship between market concentration and flight frequency. Due to the more balanced market structure resulting from mergers among leading airlines since 2002, there has been a moderate reduction in market concentration at route level, contributing to a 3.7% increase in traffic volume from 2002 to 2008. The results of our study suggest that Chinese travelers have yet to fully enjoy the benefits of market liberalization, and airports should prioritize increasing capacity related to aircraft movements over the accommodation of larger aircraft.     

基于结构方程模型的高速铁路客站旅客满意度评价研究

高速铁路客站作为中国铁路现代化的重要标志,是旅客感受高铁便捷舒适的窗口。科学合理地评价高速铁路客站的旅客满意度是检验其高服务水平的前提。根据高速铁路客站的新特点构建评价指标体系,提出了基于结构方程模型的旅客满意度评价模型,并根据高速铁路客站的服务特点修改了适当参数。以部分高速铁路客站为测评对象进行实例分析,通过分析计算结果．验证模型的可行性、适用性以及评价指标体系设置的合理性。     

西安铁路枢纽客运系统扩能方案研究

Impact of landing fees on airlines’ choice of aircraft size and service frequency in duopoly markets

A one-shot simultaneous game-theoretic model is applied in a duopoly market to investigate how airport landing fees could influence airlines’ decisions on aircraft size and service frequency. It is found that higher landing fees will force airlines to use larger aircraft and less frequency, with higher load factor for the same number of passengers. It is also found that airlines will be better off if some of the extra landing fees are returned to airlines as a bonus for airlines using larger aircraft, which consequently reduces airport congestion.

Airline Code-share Alliances and Costs: Imposing Concavity on Translog Cost Function Estimation

This paper provides an assessment of how airline code-share alliances affect the costs of the airline industry. It makes two contributions to the literature. First, it measures the effects of airline alliances by estimating a translog cost function using a panel dataset of 10 major U.S.-based airlines over 29 quarters. Secondly, it ensures concavity of the estimated cost function by using the procedure suggested by Ryan and Wales (2000, Economics Letters 67, 253–260). A conventional translog cost function is first estimated and scale estimates are computed. Unfortunately, the estimated function fails the curvature requirement, which makes interpreting the estimated effects of alliances somewhat dubious. Hence, we re-estimate the cost function by imposing local concavity restrictions. We find that large alliance partners have a small negative effect on airlines costs, but small alliance partners effect on costs appear to be positive, although the magnitude is negligible. We also find material differences in the estimates of scale economies after imposing local concavity.JEL classification: L00, L12, L93
