α: calibrated so average coauthorship-adjusted count equals average raw count
We develop a model of a two‐sided asset market in which trades are intermediated by dealers and are bilateral. Dealers compete to attract order flow by posting the terms at which they execute trades—which can include prices, quantities, and execution speed—and investors direct their orders toward dealers who offer the most attractive terms. We characterize the equilibrium in a general setting, and we illustrate theoretically and numerically how the model can account for several important trading patterns in over‐the‐counter markets, which do not emerge from existing models.
