This book presents a thorough overview of contemporary investing challenges and analyses how behavioral and neuroeconomics research can inform our understanding of the investment landscape today. It brings forward an original conceptual framework – the Triadic system (Deterministic-Stochastic-Divine) to analyse our understanding of rational behaviour. Combining economic theory with practical insights and applications, the book explores major obstacles to rational, informed investing, and how psychological biases shape financial and emotional decisions. Integrating perspectives from behavioral finance and neuroeconomics into the domain of personal finance, the book both advances research in this emergent field while outlining practical long-term wealth management strategies. Chapters consider topics such as the role of social media bombardment on investment decisions, postmoney theory and the concept of ‘buying life, buying health’, traditional investment planning versus the speed of fintech platforms, and the multifaceted impact of AI on investing. This will be a fascinating read for academics working on corporate finance and asset management, behavioral finance and economics, and artificial intelligence, as well as professionals working in these related areas.
