In a series of experiments, we investigate the sources of errors in economic decisions under risk. The first source is a “strength of preference” effect. Error rates increase and response times become longer as choice difficulty increases, in analogy with well-known psychophysical effects in perceptual discrimination tasks. The second source of errors reflects the presence of mental shortcuts capturing heuristics or behavioral rules, which interact with and modify the gradual effects arising from the strength of preference. The interaction of qualitatively different decision processes delivers testable hypotheses on errors and response times. Specifically, whenever decision processes are in conflict (prescribe different responses), error rates increase and errors are faster than correct responses. If different processes are in alignment, however, errors are slower than correct responses. These predictions become a test for the presence of multiple decision processes in economic decision making.
Carlos Alós-Ferrer graduated in Mathematics at the University of Valencia (Spain) and received his Ph.D. in Economics at the University of Alicante (Spain) in 1998. After his Ph.D. he moved to Vienna (Austria) as Assistant Professor, conducting research on game theory and mathematical economics. He became associate professor at the University of Salamanca (Spain) in 2002 and moved back to Vienna as associate professor in 2004, before becoming a full professor in Konstanz (Germany) in 2005. He became increasingly interested in “Psychoeconomics,” defined as the confluence of psychology, economics, and neuroscience to study human decision making. In 2012 he moved to the University of Cologne (Germany) as full professor of microeconomics. From 2012 to 2018, he was the speaker of the interdisciplinary Research Unit “Psychoeconomics,” funded by the German Research Foundation (DFG). In 2018, he joined the University of Zurich as Professor of Decision and Neuroeconomic Theory. Professor Alós-Ferrer has remarkable publications in the fields of economics, psychology, and neuroscience. His studies are published in journals like Journal of Economic Theory, Games and Economic Behavior, Management Science, Economic Theory, Journal of Economic Psychology, Judgement and Decision Making, Journal of Neuroscience, Psychology, and Economics, and Frontiers in Psychology.
