The perceived credibility of quality labels: a scale validation with refinement

In this paper, we present quality labels as signals that reduce problems that arise under asymmetric information. We propose to closely scrutinize the concept of signal credibility, which is a key determinant of signalling effectiveness. In order to assess the perceived credibility of a quality label, we offer a revisited version of a scale originally proposed by Larceneux. The data used in this paper involve three different labels and were collected using self‐report surveys administered to 602 respondents. Based on findings from a variety of reliability and validity tests, the scale demonstrates good psychometric properties. Both theoretical and managerial implications are discussed, along with limitations and future research directions.
