We show in a model of over-the-counter trading that customers in equilibrium may choose to contact very few dealers to incentivize maximum liquidity provision—“less is more.” This happens when dealers’ liquidity supply is sufficiently elastic to competition. A social planner would mandate even fewer contacts than the market outcome, because customers induce excessive dealer competition. The model generates predictions that echo empirical evidence, yields implications for regulation and design of electronic platforms, and speaks to customers’ order splitting behavior and their trading costs.

Keywords: over-the-counter markets, dealers, trading connections, request-for-quote
