概要 This study theoretically and empirically investigates how Knightian uncertainty about stock returns influence brokerage commissions via investors’ stock demand. We model a stock market wherein oligopolistic brokers mediate financial transactions among uncertainty-averse investors. We find that a deterioration of fundamentals about stock returns reduces the equilibrium commission, whereas an increased uncertainty raises it. Based on panel data for Canada, Japan, the United Kingdom, and the United States from 2010:Q4 to 2021:Q4, we present empirical results that support our theoretical findings.
