Which antecedents contribute most to the loyal behaviour of online second-hand market shoppers?

In the last 15 years, online sales of second-hand products have grown substantially due to changes in the economy, increasing interest in sustainability and the new opportunities offered by the alternative markets. However, little is known about the antecedents of customer retention in this particular online market. To this effect, the aim of this research is to bring new insights about what retains shoppers and creates loyal behaviour in this market by presenting a loyalty model based on expectancy-value theory and building on Olsen's satisfaction-loyalty model.

To achieve the above-mentioned purpose, a survey comprised of 507 respondents who had purchased second-hand products via an online platform during 2020 was used to test the model.

The results validate both the satisfaction-loyalty model and the mediator role of the fulfilment of expectations between perceived quality and satisfaction. The results also indicate that customer fulfilment of expectations depends only on the perception of product quality. Perceived product quality was also the dimension that most influenced satisfaction, followed by perceived vendor quality. Last, the dimensions that contributed most to loyal behaviour were satisfaction with the vendor and with the website.

The originality of this research lies in the validation of the unique satisfaction-loyalty model for online second-hand purchases. The value of this research is that it adds knowledge about effective strategies for platform owners and sellers to enhance customer satisfaction and loyalty in online second-hand markets.
