Behavioral Economics: Prospect Theory and Loss Aversion
Behavioral economics examines how psychological factors influence economic decisions. Prospect theory, developed by Kahneman and Tversky, explains that people value gains and losses differently, often making decisions based on perceived gains rather than actual outcomes. Loss aversion, a key concept within prospect theory, suggests that individuals experience the pain of losses more intensely than the pleasure of equivalent gains, leading to risk-averse behavior and choices that deviate from traditional rational economic models.

❓ Frequently Asked Questions
What is prospect theory?
Prospect theory is a behavioral model of decision-making under risk. It suggests people evaluate outcomes relative to a reference point, weigh losses more heavily than gains (loss aversion), and distort probabilities rather than assess them objectively.
What is loss aversion?
Loss aversion is the tendency to feel the pain of losses more strongly than the pleasure of equivalent gains, influencing risk choices and how options are framed.
How does framing affect decisions?
Choices can shift depending on whether options are framed as gains or losses, even when the actual outcomes are the same.
How does prospect theory differ from traditional economic models?
Prospect theory accounts for human psychology by using a reference-point-based value function, loss aversion, and probability weighting, explaining why people deviate from purely rational choices.
