Fairley, K., Fornwagner, H. and Okbay, A. (2024). Brains, hormones, and genes: Introduction to the special issue on the biological foundations of economic decision-making Journal of Economic Psychology, 100:1--11.

The Journal of Economic Psychology's previous Special Issue related to biology - the Special Issue on Decision Neuroscience by Smith and Huettel (2010) - was released over a decade ago. Since then, technological advances have led to better data availability and methodologies across various scientific fields. New techniques and biomedical measures, such as brain stimulation and genotyping, have become more accessible to researchers. Therefore, we found it timely to organize a Special Issue on the Biological Foundations of Economic Decision-Making. The Introduction to this Special Issue will provide an overview of the latest research findings in this field and the selected papers for this Special Issue. The different contributions are grouped into three main subtopics, namely Neuroeconomics, hormones and neuroendocrine signaling, and studies utilizing genetic information.
