# A NEW VARIANT OF THE MINORITY GAME - Asset Value Game and Its Extension

### Jun Kiniwa, Takeshi Koide, Hiroaki Sandoh

#### Abstract

A minority game (MG) is a non-cooperative iterated game with an odd population of agents who make bids whether to buy or sell. Based on the framework of MG, several kinds of games have been proposed. However, the common disadvantage in their characteristics is to neglect past actions. So we present a new variant of the MG, called an asset value game (AG), in which every agent aims to decrease a mean asset value, that is, an acquisition cost averaged through the past actions. The AG, however, is too simple to reproduce the complete market dynamics. So we further consider an improvement of AG, called an extended asset value game (ExAG), and investigate their features and obtain some results by simulation.
