Abstract
The very first paper published in the Journal of Mathematical Economics, “Subjectivity and correlation in randomized strategies”, by Aumann, proposes a new approach to strategic form games by taking account of an extraneous space of states of the world, on which every player has a subjective probability distribution and private information. We review some of Aumann’s results as well as some properties and extensions of the best known by-product of his seminal paper, the “correlated equilibrium”.
期刊介绍：
The primary objective of the Journal is to provide a forum for work in economic theory which expresses economic ideas using formal mathematical reasoning. For work to add to this primary objective, it is not sufficient that the mathematical reasoning be new and correct. The work must have real economic content. The economic ideas must be interesting and important. These ideas may pertain to any field of economics or any school of economic thought.
