I shall be particularly concerned in this lecture with Arrow's path-breaking "impossibility theorem," for which Arrow managed to find, in line with his sunny temperament, a rather cheerful name: "General Possibility Theorem.

Pages 13 This preview shows page 10 - 13 out of 13 pages. Arrow’s impossibility theorem, or Arrow’s paradox demonstrates the impossibility of designing a set of rules based on Ordinal Voting for social decision making that would obey every ‘reasonable’ criterion required by society.. Arrow’s Impossibility Theorem For three or more candidates, the only procedure that satisfies the above four axioms is a dictatorship, in which the outcome of an election always agrees with a specified voter’s preferences.

RecapVoting ParadoxesPropertiesArrow’s Theorem Condorcet Condition If there is a candidate who is preferred to every other candidate in pairwise runo s, that candidate should be the winner While the Condorcet condition is considered an important Before tackling Arrow’s own Social Choice and Individual Values, you might try the easier Arrow’s Theorem: The Paradox of Social Choice (Yale, 1980) by Alfred MacKay who has an engaging analogy between aggregating preferences into a social choice rule and aggregating performances in decathlon events into an overall score. Presentation Suggestions: One often hears people say that Arrow proved “there are no good/fair election methods”. The latter refers to social welfare functions: that is, to rules that assign a transitive preference relation to each preference profile. Arrow’s original proof of his impossibility theorem proceeded in two Arrow’s Impossibility Theorem 219 13.4. Arrow Lecture Columbia University December 11, 2009 ... Like Amartya, I will talk about the Arrow impossibility theorem, but I will concentrate on its implications for voting and elections; I will leave aside its broader implications for social welfare.

Among the most important advances in the social sciences of the 20 th century is Kenneth Arrow’s Impossibility Theorem.The full explanation of this theorem first appeared in Arrow’s 1951 book, Social Choice and Individual Values.As explanations go, this one is especially beautiful in its rigor, yet highly technical and inaccessible to the general public.
