This paper presents a quantitative approach to measure market efficiency based on the waiting-time distribution. We use the spread between two classes of ordinary shares of Royal Dutch Shell Plc, and two listings of Australia and New Zealand Banking Group Limited to observe market inefficient states. We find that the parameter of the waiting-time distribution provides a quantitative measure of the market inefficiency and can be used as a short-term market efficiency indicator. This approach can be applied to liquid financial markets and has clear implications for the investors, hedgers, regulators and policymakers.
