Arrow’s Independence Condition and the Bergson—Samuelson Tradition

One of the most controversial and widely misunderstood components of Kenneth Arrow’s pathbreaking work on social choice (1951; 1963) is the condition of independence of irrelevant alternatives (IIA). It is thus not out of place on the occasion of Arrow’s 65th birthday to re-examine that condition and some related issues. These keywords were added by machine and not by the authors.
