Key Concepts

St. Petersburg Paradox

This is a classical problem in probability and decision theory, where a game with an infinite expected monetary payoff contradicts what people are actually willing to pay to play it. It highlights the limitations of relying solely on expected value calculations and has been influential in the development of concepts like risk aversion and utility theory.

Two Envelope Paradox

This is another decision-making puzzle where two envelopes contain different amounts of money, and reasoning appears to always favor a switch between them, creating a seemingly endless loop of indecision. It raises questions about the validity of simplistic expected value computations, particularly in cases involving uncertainty and improper probability assessments.

Expected Value Limitations

Both paradoxes expose how standard expected value calculations can lead to counterintuitive or paradoxical conclusions, especially when dealing with outcomes that are unbounded or involve infinite sums. This realization has been crucial in refining economic and probabilistic models to better mirror realistic decision-making scenarios.

Utility Theory and Risk Aversion

In response to these paradoxes, utility theory introduces the concept of diminishing marginal utility, where the subjective value of money decreases with increasing wealth. This adjustment helps explain why individuals do not act on the infinite expected payoffs suggested by naive calculations, aligning theoretical predictions more closely with observed behavior.
