Recent Work

Working on an out-of-equilibrium model of trading both from an analytical angle, deriving asymptotic results, and numerical angle. This poster from ECCS 2009 gives a general introduction to the questions/structure of the model, approaching things from a "complexity" rather than "economics" viewpoint which may be good or bad depending on who you are. The key distinctive features of the model are:

“Zero” information: contrary to most economic models we assume agents do not know much about other agents. In particular they do not know other agent’s utility functions or bundles; they make and receive offers.

Cautious Trading: Given agent’s lack of information they do not act in anticipation of uncertain future utility, they will only make trades which immediately improve their situation.
