Changes in the effect of credence cues on restaurant delivery service under different health risks

Abstract

Purpose

Due to increased health concerns, restaurant customers rely more on credible cues that indirectly represent health-related credence quality. To comprehensively understand the dynamics between credence cues and restaurant delivery with different infection risks, this study aims to investigate changes in cue utilization during the pandemic.

Design/methodology/approach

Data on delivery sales, brand and review rating between 2019 and the first half of 2020 were obtained from Meituan. Fixed-effects estimation was used to investigate 579,858 restaurant observations across 338 cities in China.

Findings

Health concerns significantly increased the use of restaurant delivery and the increased delivery sales remained steady even after infection risk was reduced. However, cue utilization in restaurant delivery substantially changed depending on inflection risk. In the pandemic-spreading period, the sales effect of the brand increased while that of review rating decreased. The decreased effect of review rating was recovered in the pandemic-flattening period, whereas the abnormal brand effect continued only when branded restaurants had a high rating.

Research limitations/implications

The findings demonstrate the selective and contextual nature of cue utilization in the restaurant delivery setting. These characteristics are also manifested in a health crisis from a credence cue perspective.

Practical implications

The findings demonstrate the selective and contextual nature of cue utilization in the restaurant delivery setting. These characteristics are also manifested in a health crisis from a credence cue perspective. Further, this study re-conceptualizes credence quality and cues, considering their roles in risk management. The findings help develop risk management strategies based on customers’ usage patterns of credence cues in health crises.

Originality/value

The dynamics between credence cues and restaurant delivery has not been comprehensively investigated, especially when infection risk changes. This study delivers theoretical and practical contributions about how to use credence cues in the restaurant business amid health crises.
