In the Editors view, the formal mathematical expression of economicideas is of vital importance to economics. Such an expression can determine whether a loose economic intuition has a coherent, logical meaning. Also, a full formal development of economic ideas can itself suggest new economic concepts and intuitions.

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 should have real economic content. The economic ideas should be interesting and important. These ideas may pertain to any field of economics or any school of economic thought. The economic ideas may be well-known, provided they are expressed and developed in a novel way.
