A political science model based on rational choice used to explain why citizens do or do not vote. The alternative equation is V = pB + D > C. Where for voting to occur the (P)robability the vote will matter "times" the (B)enefit of one candidate winning over another combined with the feeling of civic (D)uty, must be greater than the (C)ost of ...
The rational choice model, also called rational choice theory refers to a set of guidelines that help understand economic and social behaviour. [1] The theory originated in the eighteenth century and can be traced back to the political economist and philosopher Adam Smith . [ 2 ]
The mythological Judgement of Paris required selecting from three incomparable alternatives (the goddesses shown).. Decision theory or the theory of rational choice is a branch of probability, economics, and analytic philosophy that uses the tools of expected utility and probability to model how individuals would behave rationally under uncertainty.
Social choice theory is a branch of welfare economics that extends the theory of rational choice to collective decision-making. [1] Social choice studies the behavior of different mathematical procedures ( social welfare functions ) used to combine individual preferences into a coherent whole.
For example, from the viewpoint of rational choice theory, the expected gains of voting depend on (1) the benefit to the voter if their candidate wins and (2) the probability that one's vote will determine the election's outcome. [38] Even in a tight election the probability that one's vote decides the outcome is estimated at effectively zero. [40]
Election science combines the theoretical study of social choice theory (a branch of math and welfare economics) with empirical research dealing with the administration of elections (a branch of political science). The "butterfly ballot" used in Palm Beach County was suspected of causing Al Gore's supporters to accidentally vote for Pat Buchanan
Ranked-choice voting or RCV is a system that only some states and counties use, but there's a growing push to implement it in wider U.S. elections.
We will prove that any social choice rule respecting unanimity and independence of irrelevant alternatives (IIA) is a dictatorship. The proof is in three parts: We identify a pivotal voter for each individual contest (A vs. B, B vs. C, and A vs. C). Their ballot swings the societal outcome. We prove this voter is a partial dictator. In other ...
