If you are interested in a career in finance or that touches finance (legal, regulatory, corporate, public policy), this course will give you a useful perspective. We will survey the players and current landscape of the global markets as the world continues to evolve from the financial crisis. We will discuss the sweeping change underway at the policy level by regulators and legislators around the world and this will include guest-lecturer perspectives on where the greatest opportunities exist for students entering or touching the world of finance today. The course will also review, in a non-technical way, the basics of the financial derivatives and other quantitative techniques that are a core part of the global capital markets. Elements used in grading: Class Participation, Attendance, Final Paper.
