Opinion dynamics in finance and business: a literature review and research opportunities

Abstract: Opinion dynamics is an opinion evolution process of a group of agents, where the final opinion distribution tends to three stable states: consensus, polarization, and fragmentation. At present, the opinion dynamics models have been extensively studied in differrent fields. This paper provides a review of opinion dynamics in finance and business, such as, finance, marketing, e-commerce, politics, and group decision making. Furthermore, identified research challenges have been proposed to promote the future rese… Show more

“…Possible research directions may lie in a larger volume of media input (e.g., adding video sources) in sentiment analysis; updating baseline natural language processing model to perform more robust text preprocessing; applying neural networks in label training; extending samples in terms of holding period; transaction-fees; opinion dynamics (Zha et al 2020) and, user reputation research.…”

“…The popularity of the topic is also demonstrated by the number of recent review articles on opinion dynamics [ 1 , 2 , 3 , 4 , 5 , 6 , 7 ]. Most opinion models can be classified into one of two main families: continuous or discrete opinion models [ 2 , 3 , 4 , 5 ]. The second family is dominated by models with binary opinions; however, some multi-state models have also been proposed [ 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 ].…”

“…Opinion evolution is a process of fusion of agents’ opinions, in which agents interact with their friends and continuously update their opinions to reach a consensus, polarization (two conflicting or different opinions) or fragmentation (several clusters of different opinions) in the final stage [ 4 , 5 , 55 ]. Suppose that during the opinion evolution process, each agent is not only influenced by his/her friends in the network, but also maintains his/her own opinions to some extent.…”

“…The opinions can be interpreted as support in campaign [ 37 ], brand awareness in marketing [ 1 ] and market share in business [ 32 ]. In these cases, the benefits of both contestants are closely related to the collective opinion of all agents [ 5 ]. Suppose that each contestant is rational economic man, and the only thing he/she cares about is competing for the opinions of all agents to maximize the consensus and thus maximize his/her benefits.…”
