Behavioural economics is a field of study that seeks to understand how psychological, social, and emotional factors influence economic decision-making. There are various synonyms for this term, such as behavioural finance, neuroeconomics, cognitive economics, and psychological economics. These fields all share a common goal of studying human behaviour in relation to economic decisions but may focus on different aspects of decision-making. For example, behavioural finance looks at how emotional factors such as fear and greed influence financial decision-making, while neuroeconomics uses brain imaging technology to understand how the brain processes economic decisions. Ultimately, each of these fields aims to provide a better understanding of human behaviour in the world of economics.
