Liquidity Formation and Preopening Periods in Financial Markets

This paper studies the role of preopening periods in financial markets. Because no transaction occurs during these preopening periods, their economic significance could be questioned. We model a market where costly participation and asymmetric information prevent latent liquidity to be expressed. We show that introducing a preopening period enhances liquidity and welfare. At equilibrium, risk-averse insiders use the preopening period to attract latent liquidity by communicating their trading needs and/or their private information concerning an asset’s valuation. This communication avoids market breakdown because it induces savings on the cost of market participation, and because it reduces the adverse selection risk borne by the liquidity providers. We provide implications of our analysis for the estimation of transaction costs and for the design of financial markets.
