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.     

Responding to negative online reviews: The effects of hotel responses on customer inferences of trust and concern

Our research examines the perceptions and evaluations of prospective customers toward an online negative review and any accompanying hotel response. The study explores two main issues: whether the presence (versus absence) of an organizational response to negative customer reviews affects the inferences potential consumers draw about the target business, and which aspects of responses affect their impressions. We test the effects of four variables associated with a response: source of response, voice of responder, speed of response, and action frame on two outcomes variables (i.e., customer concern and trust inferences). The provision of an online response (versus no response) enhanced inferences that potential consumers draw regarding the business's trustworthiness and the extent to which it cares about its customers. Using a human voice and a timely response yielded favorable customer inferences. Inferences did not vary with response source or action frame. Implications are drawn for effective management of negative online reviews.     

Another look at long memory in common stock returns

We apply the modified rescaled range test to the return series of 1,952 common stocks. The results indicate that long memory is not a widespread characteristic of these stocks. But logit models of the event of a test rejection reveal that rejections are linked to firms with large risk-adjusted average returns. The maximal moment of a return distribution is also found to influence the event of a rejection, but not in a way suggestive of moment-condition failure. Evidence suggestive of survivorship bias is also uncovered. We conclude that there is some evidence consistent with persistent long memory in the returns of a small proportion of stocks.     

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.     

The influence of guarantees,active requests to voice and failure severity on customer complaint behavior

Anecdotal evidence suggests that service guarantees and requests by service workers to complain encourage customers to voice following failure, while holding negative word of mouth and exit at bay. However, empirical support for these tactics is limited. To address this deficiency, we conducted an experiment examining the influence of these devices on customer complaint behavior (CCB) across restaurant failures of varying severity. Findings suggest that offering a guarantee, regardless of it being unconditional or combined, encourages voice. Failure severity had the strongest influence on CCB, and it interacted with both active request and guarantee type in influencing exit. Theoretical and managerial implications of the findings are discussed.     

Government Deposit Insurance and the Diamond-Dybvig Model

The apparent banking market failure modeled by Diamond and Dybvig [1983] rests on their inconsistently applying their sequential servicing constraint to private banks but not to their government deposit insurance agency. Without this inconsistency, banks can provide optimal risk-sharing without tax-based deposit insurance, even when the number of type 1 agents is stochastic, by employing a contingent bonus contract. The threat of disintermediation noted by Jacklin [1987] in the nonstochastic case is still present but can be blocked by contractual trading restrictions. This article complements Wallace [1988], who considers an alternative resolution of this inconsistency.
