Book excerpt: We develop and test a model that provides improved estimates of the bid-ask spread's cost components: order processing, adverse selection, and inventory control. The model incorporates three unique features: (1) a dealer's response to inventory imbalances is not static but depends on the size of the imbalance and the dealer's aversion to inventory risk; (2) active inventory management by a dealer will result in a stationary stochastic process for inventory; and (3) inventory management will influence the adverse selection cost component. We estimate the spread's components using intraday data for NYSE/AMEX and NASDAQ stocks. We also examine the impact of our model's features on the cost estimates. The results suggest inventory costs are higher and order processing costs are lower than previously reported.
