  2. Rational choice model - Wikipedia

    en.wikipedia.org/wiki/Rational_choice_model

    Individuals make no difference to the outcome, “much as single molecules make no difference to the properties of the gas" [citation needed] (Herbert, G). This is a weakness of rational choice theory as it shows that in situations such as voting in an election, the rational decision for the individual would be to not vote as their vote makes ...

  3. Occam's razor - Wikipedia

    en.wikipedia.org/wiki/Occam's_razor

    Therefore, to the same natural effects we must, as far as possible, assign the same causes." [20] [21] In the sentence hypotheses non fingo, Newton affirms the success of this approach. Bertrand Russell offers a particular version of Occam's razor: "Whenever possible, substitute constructions out of known entities for inferences to unknown ...

  4. Expected utility hypothesis - Wikipedia

    en.wikipedia.org/wiki/Expected_utility_hypothesis

    He proposed that a nonlinear function of the utility of an outcome should be used instead of the expected value of an outcome, accounting for risk aversion, where the risk premium is higher for low-probability events than the difference between the payout level of a particular outcome and its expected value. Bernoulli further proposed that it ...

  5. Causal analysis - Wikipedia

    en.wikipedia.org/wiki/Causal_analysis

    Causal analysis is the field of experimental design and statistics pertaining to establishing cause and effect. [1] Typically it involves establishing four elements: correlation, sequence in time (that is, causes must occur before their proposed effect), a plausible physical or information-theoretical mechanism for an observed effect to follow from a possible cause, and eliminating the ...

  6. Von Neumann–Morgenstern utility theorem - Wikipedia

    en.wikipedia.org/wiki/Von_Neumann–Morgenstern...

    The lottery ′ is, in effect, a lottery in which the best outcome is won with probability (), and the worst outcome otherwise. Hence, if u ( M ) > u ( L ) {\displaystyle u(M)>u(L)} , a rational decision maker would prefer the lottery M {\displaystyle M} over the lottery L {\displaystyle L} , because it gives him a larger chance to win the best ...

  7. Risk aversion (psychology) - Wikipedia

    en.wikipedia.org/wiki/Risk_aversion_(psychology)

    Most theoretical analyses of risky choices depict each option as a gamble that can yield various outcomes with different probabilities. [2] Widely accepted risk-aversion theories, including Expected Utility Theory (EUT) and Prospect Theory (PT), arrive at risk aversion only indirectly, as a side effect of how outcomes are valued or how probabilities are judged. [3]

  9. Rational expectations - Wikipedia

    en.wikipedia.org/wiki/Rational_expectations

    Lucas’ paper “Expectations and the Neutrality of Money” expands on Muth's work and sheds light on the relationship between rational expectations and the monetary policy. The paper argues that when individuals hold rational expectations, changes in the money supply do not have real effects on the economy and the neutrality of money holds.
