Practical Applications of Price Discovery: The Economic Function of a Stock Exchange

Abstract

Everybody knows that the function of a stock exchange is to bring buyers and sellers together. But there is another function that is underappreciated and yet is vitally important. It is price discovery, and regulators and exchanges need to pay more attention to it, according to the authors of this research.

In this Practical Applications report and accompanying video interview, co-authors Nazli Sila Alan and Robert Schwartz detail their research on NYSE and NASDAQ intraday volatility.
