Module 1: Core Concepts of Prospect Theory
Definition and Framework: Prospect Theory, introduced by Daniel Kahneman and Amos Tversky in 1979, contrasts with traditional utility theory by incorporating psychological factors into the understanding of decision-making under risk. It suggests that individuals do not always act rationally in pursuit of expected utility maximization.
Loss Aversion: This principle illustrates that losses typically affect individuals more than gains of a similar size. Research indicates that losses are perceived as 1.5 to 2 times more impactful than gains, leading to prioritization of loss avoidance in decision-making processes.
Framing Effects: The manner in which choices are presented, or 'framed', can significantly influence decisions. This demonstrates that individuals' choices can vary substantially depending on the context of the information provided, further complicating the rational decision-making model.
Module 2: Historical Context and Background
Emergence in the 1970s: Prospect Theory arose during a time of paramount change in economic thought, highlighting discrepancies in traditional models of decision-making. Economists began to recognize that human behavior often deviates from the rational actor model espoused by expected utility theory.
Cognitive Psychology Influence: The integration of cognitive psychology into economics was pivotal. It shed light on how psychological factors such as biases and heuristics influence decision-making, highlighting the limitations of classical economic assumptions.
Behavioral Economics Foundation: Prospect Theory is a cornerstone of behavioral economics, demonstrating that rationality is often a myth. This field emphasizes the inconsistencies in human behavior when faced with uncertainty, enriching the understanding of market dynamics.
