To contact me:

Alex Zimper moved Sept 2011 from Wits to the University of Pretoria. He holds a PhD in Economics from the University of Mannheim and he has previously worked at the Universities of Cape Town, Leicester, and Johannesburg. 

He started out as a specialist on iterative solution-concepts for strategic games, but his current research interests concern topics in Economic Theory in the broadest sense. He does not believe that there is one big truth out there but rather that classical as well as bounded-rationality approaches provide us with structures that may improve—within their respective limits—our understanding of reality.

His most recent work is on plausible refinements of Roy Radner’s rational expectations equilibrium, existence and uniqueness of an equilibrium price function in a Lucas fruit-tree economy with ambiguous beliefs, over- and under-reaction in asset markets, and optimal liquidity provision under demand deposit schemes. His work in decision theory mainly concerns dynamically inconsistent behaviour arising from ambiguity attitudes and, in particular, Bayesian learning modelled within non-additive probability spaces.
