Trading and Exchanges Chapter 14: Spread Components and What They Tell You (Part 2)
In Part 1 we covered dealer spreads, the two spread components (transaction costs and adverse selection), and why uninformed traders lose no matter what order type they use. Now Harris finishes the chapter with equally important stuff: what determines equilibrium spreads in real markets, how public traders compete with dealers, and what factors predict whether a given instrument will have wide or narrow spreads.
