Rational Expectations and Depth of Reasoning 

Strategic interaction is very important in many areas of human (and non-human) behaviour. Economists are particularly interested in the type of strategic interaction that arises in financial markets, where there are large numbers of agents, whose success in decision-making depends crucially on the correctness of their beliefs regarding the strategies adopted by other agents. The “standard guessing game”, sometimes called the “beauty contest game”, provides a very useful means of observing strategic interactions in a controlled setting. It can be played with any number of players (two or more).

The most popular framework for the analysis of data from such an experiment is the “level-k” model. This model assumes the co-existence of agents with different “levels of reasoning”. Level-0 agents are assumed to choose their actions randomly; Level-1 gents are assumed to believe that all other agents are Level-0, and to best-respond  to this belief; Level-2 agents assume all others are Level-1; and so on.

The limit of this process is the fully rational Level agent whose behaviour corresponds to the Nash-equilbrium prediction. 


Using Econometric methods, we analyse data from a Guessing Game experiment administered by a newspaper on its readership. The key result is that the most advanced reasoners tend to over-estimate the proportion of the population who are of similar mind. This is interpreted as a manifestation of the Dunning-Kruger effect.
