An Analysis of Bounded Rationality in Judicial Litigations : The Case with Loss/Disappointment Averse Plaintiffs

For psychologists, bounded rationality reflects the presence of cognitive dissonance and/or inconsistency, revealing that people use heuristics (Tversky and Kahneman (1974)) rather than sophisticated processes for the assessment of their beliefs.
