....estigious journal "Computational Management Science", the study explores the growing concerns and potential solutions of algorithmic bias and collusive practices on digital marketplaces. According to Dipankar Das, Assistant Professor at GIM, Current digital marketplaces often use ranking algorithms that prioritise revenue generation. "This has led to serious issues such as manipulated customer....

.... reviews, platform self-preferencing, and opaque search result algorithms. As a result, genuine sellers face limited visibility, market competition becomes distorted, and consumers are exposed to misleading product information," Das said. "The algorithm developed is a potential option to bring transparency and fairness to product rankings. By explicitly modelling the competitive dynamics between....
