Within this course you will learn about price formation and liquidity in securities markets. You will discover the determinants of market depth and security trading. In particular, the course focuses on price formation and liquidity in securities markets. The main issues covered are how to measure trading costs; how security prices, their liquidity and speed of price discovery are jointly determined, and how order flow affects prices; what are the determinants of market depth; how security trading is organized and regulated and how it has been reshaped by algorithmic and high frequency trading; how the organization of security trading affects trading costs and informational efficiency.
This module presents the subject of the course and its main concepts: liquidity and price discovery, and basic notions of trading in securities markets.
