Arrow's impossibility theorem

Social Choice and Individual Values Kenneth Arrow's monograph ''Social Choice and Individual Values'' (1951, 2nd ed., 1963, 3rd ed., 2012) and a theorem within it created modern social choice theory, a rigorous melding of social ethics and voting theory with an economic flavor. ...
'' derives from his 1951 PhD thesis. In what he named the General Impossibility Theorem, he theorized that, unless we accept to compare the levels of utility reached by different individuals, it is impossible to formulate a social preference ordering that satisfies all of the following conditions: # Nondictatorship: The preferences of an individual should not become the group ranking without considering the preferences of others. # Individual Sovereignty: each individual should be able to order the choices in any way and indicate ties # Unanimity: If every individual prefers one choice to another, then the group ranking should do the same # Freedom From Irrelevant Alternatives: If a choice is removed, then the others' order should not change # Uniqueness of Group Rank: The method should yield the same result whenever applied to a set of preferences. The group ranking should be transitive. The theorem has implications for

Information economics

In other pioneering research, Arrow investigated the problems caused by asymmetric information in markets. In many transactions, one party (usually the seller) has more information about the product being sold than the other party. Asymmetric information creates incentives for the party with more information to cheat the party with less information; as a result, a number of market structures have developed, including
warranties In contract law, a warranty is a promise which is not a condition of the contract or an innominate term: (1) it is a term "not going to the root of the contract",Hogg M. (2011). ''Promises and Contract Law: Comparative Perspectives''p. 48 Cambri ...

Arrow analysed this issue for medical care (a 1963 paper entitled "Uncertainty and the Welfare Economics of Medical Care", in the American Economic Review); later researchers investigated many other markets, particularly second-hand assets, online auctions and insurance.
