Biography
Spyros is Professor in Economics and Director of the DREAM Research Centre. He has held academic positions at the University of Southampton (Lecturer and Associate Professor) and City, University of London (Senior Lecturer, Reader and Head of Department). He received his PhD from the University of Rochester in 2008, his MSc from the University of Warwick in 2002 and his BSc from the Athens University of Economics and Business in 2001, all in Economics.
His main research focuses on the role that uncertainty, information and bounded perception have on single- and multi-agent decision making. He examines under which conditions speculative trade occurs and whether information is valuable, in three different settings: when traders have a bounded perception of their uncertainty due to their unawareness, when they are dynamically and time inconsistent, and when they are not financially sophisticated enough to formulate complex trading strategies. He also studies when information is valuable and whether markets aggregate and reveal information through their price mechanism.
Spyros has been awarded an ESRC grant as PI that runs between 2021 and 2024, , and a French grant as Co-I, on the forecasting efficiency of prediction markets. The aim is to understand under which conditions the prediction markets (and financial markets more generally) are an effective tool in aggregating information. The aim is to study prediction markets theoretically and experimentally, but also to collaborate with firms in implementing them on-site and testing their effectiveness. You can find more information about the project at calimantic.com.
His work has been published in journals such as the Review of Economic Studies, Journal of Economic Theory, Games and Economic Behavior, and Economic Theory, among others. He is Director of the Durham Research in Economic Analysis and Mechanisms (DREAM) and he co-organises the Virtual Seminars in Economic Theory (VSET), the Durham Economic Theory Conference and the Makris Symposium in Economic Theory (MSET).
