Abstract:
Neuroeconomics is an emerging multidisciplinary field that examines the brain
mechanisms underlying economic decision-making by combining tools from
neuroscience, economics, and psychology. While economics traditionally studies
how limited resources are allocated, neuroscience provides powerful
measurement techniques to analyze brain activity. Therefore, neuroeconomics is
a new research area that should be further investigated. The Author conducted the
study with three main objectives. They are (1) synthesize the current knowledge
in neuroeconomics, (2) identify gaps in the existing literature, and (3) suggest
possible research directions to address these gaps. A SLR (systematic literature
review) was used for the research and PRISMA (Preferred Reporting Items for
Systematic Reviews and Meta-Analyses) rules were followed in the selection,
analysis, and reporting of the articles. The databases utilized to look for the papers
were Lens.org and Scopus from year 2005 to year 2025. The search phrase and
criterion were "neuroeconomics" & “neuroscience”. 50 articles are included in
the final review. After that, the results for analysis were produced using programs
of Vosviewer and Biblioshiny. Results show that neuroeconomics focuses on how
different brain regions evaluate subjective value, influence social and financial
decision-making, and interact with emotions and cognitive biases. Neuroimaging
techniques such as fMRI (functional magnetic resonance imaging) have been
used. Thematic analysis revealed seven research clusters: AI & Behavioral
Sciences, Emotional & Social Cognition, Computational & Motivational
Neuroscience, Neural Mechanisms of Value, Strategic & Neurofinance,
Technology & Decision Utility, and Neuroethics & Psychological Approaches.
Research gaps exist in diagnostic imaging, evoked potentials, subjective value,
and artificial intelligence, emphasize the need for deeper investigation in these
areas. This paper highlights the need for broader database coverage and proposes
integrating more diverse methodologies in future research. By linking
neuroscience with economic theory, neuroeconomics offers valuable
contributions to consumer research, finance, and policymaking.
