Quantum model of strategic decision-making in Prisoner's Dilemma game: quantitative predictions and new empirical results
Abstract
The Disjunction effect introduced in the famous study by Shafir and Tversky (1992) and confirmed by several following studies remains one of key 'anomalies' for the standard model of the Prisoner's Dilemma game. In the last 10 years, new approaches have appeared that explain this effect with the use of quantum probability theory.
But the existing results do not allow parameter-free test of these models. This paper introduces a general quantum model of Prisoner's Dilemma game as well as a new experimental design that enables to test the main quantitative and qualitative predictions of this model.
Main findings of the experi-ment support the viability of the quantum model and challenge the classical solution concept of the Prisoner's Dilemma game.
