Preferences, Prisoners And Private Information: Was Socrates Rational At His Trial?, Brishti Guha

Research Collection School Of Economics

Using concepts from game theory, political economy, law and economics and the economics of asymmetric information, we describe the economics of one of the most famous trials in history—that of the Athenian philosopher Socrates.

Our analysis sheds some light on institutional efficiency in trials that followed the classical Athenian pattern.

Consumers are rational in using the advertising search rule, since the lowest-cost firm advertises the most and also selects the lowest price. Even though the advertising equilibrium facilitates productive efficiency, we establish conditions under which firms enjoy higher expected profit when advertising is banned. Consumer welfare falls in this case, however. We next analyze a dynamic …
