Former classic economic theories mainly strengthened the concept of the ‘homo economicus’, who strongly behaves economical and rational. Nowadays however, some argue this supports not the reality, and so academic research progressed. For this, laureate Kahneman et al developed the prospect theory which is assumed to describe people’s economical behaviour better than traditional theories.
Therefore the essay elaborates on the concept of behavioural finance and econom-ics as well as it checks, whether the homo economicus has mutated to this. How-ever, although there is criticism, the hypothesis is humans are bounded rational and therefore only conditioned able to be described as homo economicus.
To gain insight, a brief introduction on theory, homo economicus and recent ob-servations of efficiency in human action and rationality is given. Later the concept of behavioural finance and economics is brought in and findings in human behav-iour are discussed together with examples from heuristics, economical framing and anomalies. Finally, an assessment of essay and hypothesis sums all up.

Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)
This essay aims to explore the concept of behavioural finance and economics, examining whether the traditional model of 'homo economicus' has evolved into this new framework. The paper will analyze the limitations of the classical economic model and its reliance on rationality, highlighting the findings of behavioural finance and economics that suggest human decision-making is often influenced by emotions, biases, and heuristics.
- Evolution of economic thought from classical models to behavioural finance and economics
- Impact of cognitive psychology on economic decision-making
- The role of heuristics, framing effects, and anomalies in human economic behaviour
- Limitations of the 'homo economicus' model in light of empirical observations
- Exploring the concept of bounded rationality and its implications for economic decision-making
Zusammenfassung der Kapitel (Chapter Summaries)
The introduction sets the stage by outlining the limitations of the traditional economic model, which assumes individuals are perfectly rational and self-interested. It introduces the concept of behavioural finance and economics as a more realistic approach that acknowledges the influence of psychology and emotions on economic decision-making.
Chapter 2 delves into the historical evolution of economic thought, tracing the shift away from psychology in the neo-classical period and the re-emergence of psychological considerations in the development of behavioural finance and economics. It explores key observations and methodologies used in this new field, including experimental studies and brain imaging techniques.
Chapter 3 explores the key findings of prospect theory, a central framework within behavioural finance and economics. It examines various heuristics, framing effects, and anomalies that influence human decision-making, providing insights into the ways in which people deviate from purely rational behavior.
