Institutional traders consider liquidity in addition to prices when they trade. Their large trades create price impacts, which incur the risks of slippage and unfavourable market conditions that adversely affect their profit. We propose a generic framework to model the market price of liquidity risk. By setting the framework's parameters appropriately, we obtain different closed-form solutions of price impact function and the market price of liquidity risk. One particular price impact function is concave with respect to the order flow. We also find a proportional relationship between illiquidity and volatility. These features of our model are qualitatively consistent with existing empirical evidence. (joint work with Christopher Ting)
