ENDOGENOUS TIMING IN QUALITY CHOICES AND PRICE COMPETITION

We modify the price‐setting version of the vertically differentiated duopoly model by Aoki (2003) by introducing an extended game in which firms noncooperatively choose the timing of moves at the quality stage. Our results show that there are multiple equilibria in pure strategies, whereby firms always select sequential play at the quality stage. We also investigate the mixed‐strategy equilibrium, revealing that the probability of generating outcomes out of equilibrium is higher than the probability of playing one Nash equilibria in pure strategies. In the alternative case with full market coverage, we show that the quality stage is solved in dominant strategies and therefore the choice of roles becomes irrelevant as the Nash and Stackelberg solutions coincide. With full market coverage and corner solution, the results show that the game has a unique subgame perfect equilibrium in pure strategies, where the high‐quality firm takes the lead in the quality stage.     

The influence of self-construal and co-consumption others on consumer complaining behavior

Consumers show great individual variability in complaining behavior even after experiencing similar service failures. The present study examined the effect of self-construal and co-consumption others on consumer complaining behavior following a service failure. Based on an experimental study with a sample of 202 in a restaurant context, MANCOVA results revealed significant effects of self-construal on voice response and switching behavior. The results also showed a significant interaction effect of self-construal and the presence of co-consumption others on switching behavior. The findings shed light into the intrapersonal and interpersonal dynamics at work when consumers react to service failures. Theoretical and managerial implications of the findings are also discussed.     

SHORT‐RUN POLICY COMMITMENT WHEN INVESTMENT TIMING IS ENDOGENOUS: ‘MORE HARM THAN GOOD?’

In our model, firms choose when to set cost‐reducing investment and the government, which only has short‐run commitment power, sets an output subsidy. We show that firms that delay investment without government intervention have an incentive to invest early under policy activism, strategically underinvesting or overinvesting to obtain larger subsidies. The policy scheme thus creates a new, potentially more harmful, distortion. Under oligopoly, a firm has a weaker incentive to manipulate policy than under monopoly, which makes policy intervention less harmful. We investigate when the government may do better by adhering to laissez‐faire than by engaging in active policy intervention.     

Tourism Market Recovery in the Maldives After the 2004 Indian Ocean Tsunami

SUMMARY

This paper will use a range of tourism data and a case study to examine the rates of recovery of ten source markets for the Maldives in the wake of the 2004 Indian Ocean tsunami. The market response and recovery rates for these ten markets varied significantly and the reasons for this will be explored. It is evident that a 'one size fits all' marketing strategy will not in itself be sufficient to achieve acceptable rates of recovery following a disaster. The strategies, opportunities and rates of market recovery experienced in the Maldives will provide useful insights for the marketing and monitoring of other destinations that have experienced a crisis or disaster.     

Service Problems,Service Crises and Service Disasters

ABSTRACT

This paper discusses the need for tourism service organisations to implement effective ways of responding to their clients when a problem occurs in the delivery of a service. Failure to recognise or respond appropriately to a problem when it occurs can cause a crisis which requires more organisational resources and skills to overcome, and if this is not achieved the original problem may result in desertion of the company by its clients, or adverse publicity impacting severely on the company's success. The paper presents a short illustrative case study. The paper suggests that organisations may learn from analysing service problems how to adopt adaptive strategies to minimse the negative consequences of future service failures. It indicates the need for further studies to improve the responsive of organisations to service problems.     

Service Recovery Efforts in Fast Food Restaurants to Enhance Repeat Patronage

Abstract

The purpose of this study is to: (a) identify service failure incidents; (b) identify service recovery efforts; and (c) determine the effects of resolution levels repeat patronage. Employee service behavior and monetary rewards were found to have a significant effect on resolution levels. The manager should provide guiding principles to improve service quality. Furthermore, mentoring and empowerment may improve employee service performance. Complete resolution leads to repeat patronage. The study found significant relationships between demographic characteristics with service failures and service recovery efforts. Lastly, there were significant relationships between the critical service failures and service recovery efforts and types of fast food restaurants.

Does delaying service-failure resolution ever make sense?

Conventional wisdom suggests that service providers should respond to their failures as quickly as possible. Some research, however, points out that delaying resolutions may produce highly desirable results. The study here investigates these competing views by examining under which conditions an immediate or a delaying resolution produces more positive consumer responses in term of re-patronage and negative word-of-mouth intentions. Based on the concept of service separation, this research identifies an interaction effect between service separation (separated service, non-separated service) and response timing (immediate response, delaying response) on consumers' post-consumption intention. This research also finds that the relationship between service separation-response timing interaction and consumer response is mediated by consumers' negative emotions. This study contributes to refining our understanding of consumer psychology in service recovery. Practically, the studies also enable service providers to better allocate their resources to recover different types of services' failure.
