| Tiivistelmä: | The central purpose of this paper is to develop a model of insider trading (i.e. , trading based on private information) in the context of an imperfectly competitive multi-security market with risk-neutral agents. Imperfect competition allows the authors to consider strategic behaviour, and a multi-security market lets them study the effect of a correlated environment on equilibrium. The authors employ the informational assumption that market makers can observe all order flows, and so portfolio diversification arises in this model for strategic reasons. |
