A market impact game is concerned with a model for competing traders whose trading strategies can impact the prices of an asset. Knowledge of the strategies of competitors can then affect the strategic decisions of each trader. In this talk, we consider Nash equilibria between traders in a simple model with transient price impact and study a number of their qualitative features. For instance, we analyze whether adding transaction costs can have a stabilizing effect on the system and whether increasing the trading frequency will decrease equilibrium costs.
The talk is based on joint work with X. Luo, E. Strehle, and T. Zhang.
