The main goal of the course is to introduce the students to the basic concepts and theories that have been developed in recent years for markets’ microstructure. More specifically, the subjects the course will study:
- The distinction of markets into primary and secondary and into markets of organized or over-the-counter mechanisms
- The theory of formation of prices and trading volumes, the concept of equilibrium and efficiency in a securities market
- The price spread and the concept of liquidity of a market and the “central” role of the central market maker
- The strategic behavior of investors and its effect on prices
- The categories of the orders and their properties
- The information asymmetry and the way it is modelled

- Autonomous work
- Team work
- Work in inter-scientific environment
