Item Enablers and Barriers in FinTech Adoption: A Systematic Literature Review of Customer Adoption and Its Impact on Bank Performance(MDPI, 2025-09-03)The rise of financial technology (FinTech) has generated substantial research on its adoption by customers and the associated implications for traditional banks. This systematic review addresses two questions: (1) What factors enable or hinder consumer adoption of FinTech? (2) How does consumer adoption of FinTech affect the performance of traditional banks? Following the PRISMA guidelines, we screened and analyzed 109 peer-reviewed articles published between 2016 and 2024 in Scopus and Web of Science. The findings show that adoption is driven by economic incentives, digital infrastructure, personalized services, and institutional support, while barriers include limited literacy, perceived risk, and regulatory uncertainty. At the bank level, adoption enhances operational efficiency, customer loyalty, and revenue growth but also generates compliance costs, cybersecurity risks, and competition. Consumer adoption studies primarily employ the Technology Acceptance Model (TAM) and the Unified Theory of Acceptance and Use of Technology (UTAUT), often extended with trust and privacy constructs. In contrast, bank performance research relies on empirical analyses with limited theoretical grounding. This review bridges behavioral and institutional perspectives by linking consumer-level drivers of adoption with organizational outcomes, offering an integrated conceptual framework. The limitations include a restriction of the retrieved literature to English publications in two databases. Future work should apply longitudinal, multi-theory models to deepen the understanding of how consumer behavior shapes bank performance.Item Leveraging fine-grained mobile data for churn detection through Essence Random Forest(Springer Nature, 2021-04-29)The rise of unstructured data leads to unprecedented opportunities for marketing applications along with new methodological challenges to leverage such data. In particular, redundancy among the features extracted from this data deserves special attention as it might prevent current methods to benefit from it. In this study, we propose to investigate the value of multiple fine-grained data sources i.e. websurfing, use of applications and geospatial mobility for churn detection within telephone companies. This value is analysed both in substitution and in complement to the value of the well-known communication network. What is more, we also suggest an adaptation of the Random Forest algorithm called Essence Random Forest designed to better address redundancy among extracted features. Analysing fine-grained data of a telephone company, we first find that geo-spatial mobility data might be a good long term alternative to the classical communication network that might become obsolete due to the competition with digital communications. Then, we show that, on the short term, these alternative fine-grained data might complement the communication network for an improved churn detection. In addition, compared to Random Forest and Extremely Randomized Trees, Essence Random Forest better leverages the value of unstructured data by offering an enhanced churn detection regardless of the addressed perspective i.e. substitution or complement. Finally, Essence Random Forest converges faster to stable results which is a salient property in a resource constrained environment.Item Toward Decision Support for Telecom External Data Monetization: A Study of the Value of Network- and Personality-Based Metrics for Third-Party Businesses(Mary Ann Liebert, 2022-04-01)The big data revolution has led to unprecedented opportunities for data sharing between industries. Telephone companies offer specific data involving rich information not only about the customer's behavior but also regarding his/her relationship with other customers and with third-party businesses. This article addresses the following research question: Might telecom data help to improve the prospective selection of third-party businesses? By answering this question, we expect to offer support for two specific investment decisions: on the one hand, the decision of the telecom operator to invest in the new market of the external data monetization for third-party business; on the other hand, the decision of third-party businesses to buy such customer profiling extracted from telecom call data records (CDRs). Using complex data treatments and more than one million models, the article addresses the challenges and opportunities in collecting and analyzing telecom data from two European telephone companies for improving the prospective selection processes of 36 third-party businesses. This improvement relies on new features extracted from the CDR, among which behavioral variables are considered as Personality Proxy variables and network-based variables. The results highlight that Personality Proxy variables are useful to support smaller niche businesses. For these businesses these variables are predominant and they can be directly implemented. In addition, the study shows that network analysis-based variables have the potential to be more beneficial to large companies since the value of network analysis continuously increases with the number of third-party business clients identified.Item Alternatives for Telco Data Network: The Value of Spatial and Referral Networks for Churn Detection(Taylor & Francis, 2021-07-03)The value of communication network has received significant attention in the literature on churn prediction, while little is known about the potential business value of alternative networks. This knowledge would help telephone companies to make timely strategic decisions in our evolving economic environment where traditional communication technologies are declining. This study assesses to which extent two alternative networks might (1) structurally substitute this network and (2) complement this network for churn prediction within telephone companies.Item Chief strategy officers: Contingency analysis of their presence in top management teams(Wiley, 2014-03)Drawing upon contingency theory, we analyze the antecedents and performance consequences of chief strategy officer ( CSO ) presence in top management teams ( TMTs ). We argue that strategic and structural complexity affects the decision to have a CSO in the TMT and its effect on firm performance. The results of a sample of S&P 500 firms over a five‐year period reveal that diversification, acquisition activity, and TMT role interdependence are positively associated with CSO presence. However, we also find that the structural choice to have a CSO in the TMT does not significantly affect a firm's financial performance. This first systematic analysis of CSO presence informs research on CSOs and contributes to the emerging literature on TMT structure . Copyright © 2013 John Wiley & Sons, Ltd.
