Economic Theory is a peer-reviewed academic journal that focuses on theoretical economics, particularly social choice, general equilibrium theory, and game theory. Mathematically rigorous articles are also published in the fields of experimental economics, public economics, international economics, development economics, and industrial organisation.
The journal is the official journal of the Society for the Advancement of Economic Theory. Both the society and the journal were founded by Charalambos D. Aliprantis, Edward C. Prescott, and Nicholas C. Yannelis.
At its inception, the journal only published quarterly, but in recent years it has begun to release issues monthly, with 3 issues constituting a volume.
