Abstract:
This paper examines the stabilizing role of a market maker who acts as both a liquidity trader and an active investor under the framework of bounded rationality. It does so by developing a stochastic dynamic asset price and market maker inventory model with heterogeneous agents changing their strategies asynchronously. Analysis of the corresponding deterministic model shows that the stabilizing role of the market maker is often limited and subtle, and can even destabilize a market when speculators are active.
The analysis also shows that, as an active investor, the market maker may have some incentive to destabilize the market. Numerical analysis of the stochastic model further demonstrates that the model is able to generate most of the stylized facts of asset returns and empirical patterns for market maker inventories observed in financial markets.
