Modeling Decisions Under Risk and Ambiguity with Quantum-Like Models

Holger Dietrich

Abstract: Research on human decision making under risk and ambiguity shows devia[1]tions between theory and reality. Recent research focused on finding possible reasons (be[1]havioral economics) for each deviation and suggesting new approaches (using heuristics) instead of investigating different probability theories. I want to test if a new probability theory, quantum probability, could solve some of the actual problems of decision theory jointly. Therefore, I evaluate a new subjective expected utility model using the data from Choice Prediction Competition 2015 (CPC, 2015). My aim is ex ante prediction of be[1]havior for a broad range of settings
