講座內(nèi)容：This talk empirically identifies business travellers’ preferences during
the COVID-19 pandemic across different regions. A stated preference study was
conducted during April to June 2021 on respondents in the U.S., the city of
Shanghai in mainland China and Hong Kong. Generalised mixed multinomial logit
(GMXL) models are estimated incorporating attributes of travel characteristics,
severity levels of the pandemic, and health control measures at the airport.
When an online meeting is inapplicable, respondents from Shanghai and Hong Kong
highly value heath control measures, and are not sensitive to the time spent at
airport health checkpoints. In comparison, U.S. respondents are averse to the
time spent for health check, the reporting of personal information, travel
history, symptoms, and the requirements of compulsory mask wearing and onsite
sample testing. However, when online meeting is applicable, all the respondents
show no appreciation for health control measures, while the U.S. respondents
are twice more averse to the time spent at airport health checkpoints. Online
meeting reduces the intention of international business travel amid the
pandemic for passengers in Shanghai and Hong Kong, but imposes no significant
effects on U.S. travellers. Such significant heterogeneity in traveller
preference partly explains the different recovery patterns observed in various
aviation markets, and justifies individualized travel arrangements and service
priority in fulfilling pandemic control requirements across different regions.
Our study also suggests that there are commonly accepted areas for global
cooperation such as the sharing of vaccination record, and the option of online
meeting calls for convenient travel arrangements amid pandemic to all
countries.

講座內(nèi)容：The aviation industry has proposed the collective goal of achieving net-zero carbon emissions by 2050. In addition to the existing market-based mechanisms, the use of renewable energies, in particular, sustainable aviation fuel (SAF), could be one of the most promising means of for achieving this long-term target. This paper investigates how an SAF mandate from the government can lead to heterogeneous impacts on two types of airlines, namely, full-service carriers (FSCs) and low-cost carriers (LCCs), that compete in the same markets. A game-theoretic economic model is constructed that accounts for the different service quality levels and cost structures (i.e., fuel efficiency) between FSCs and LCCs. Our analytical results suggest that the SAF mandate favors LCCs over FSCs. The share of SAF blended into fuel raises the airfares of both types of airlines while reducing the traffic and profit of FSCs. The impacts on the LCC traffic and profit depend on its fuel efficiency relative to that of FSC. When LCCs are sufficiently fuel efficient, the SAF mandate can increase their traffic and profit. We also examine how air passengers’ environmental awareness affects the outcomes of SAF mandate implementation. Our economic model also accounts for passengers’ heterogeneous preferences in terms of service quality and price sensitivity. Overall, this study suggests that the SAF mandate could provide a competitive edge for LCCs against FSCs.
