GOALS OF THE COURSE
At its core, economics is the study of how to best allocate scarce resources. The way in
which those scarce resources should be optimally allocated over time is the focus of the
sub-field of economics known as finance, which has become both popular and
sophisticated over the past two decades. The costs and benefits of financial decisions are
often challenging to evaluate since they are spread out over months or years and are not
known with certainty. The goal of this course is to develop and apply the main tools of
modern finance in order to understand the crucial role of financial markets and financial
decision making in the economy.
We will pay special attention to theories of how assets are priced, including the pricing of
financial derivatives such as options and futures. We will also examine the possible
explanations for the recent financial market turmoil, including events in the mortgage
markets, bond markets and stock markets around the world.
BY THE END OF THIS COURSE, YOU SHOULD BE ABLE TO:
• Explain the ways in which financial markets can contribute (or not) to economic
efficiency and the transfer of risk
• Analyze the principles that underlie optimal portfolio strategies
• Understand the theory of options pricing and its various applications
• Explain the role of the “no arbitrage” condition
• Evaluate hedging strategies
• Describe the development of asset securitization and the risks it may pose, as in the
case of certain mortgage-backed securities
• Use models of securities prices in discrete time
• Understand the limits of the efficient markets hypothesis (EMH)
• Use the capital asset pricing model (CAPM) and its extensions to value securities and
understand the limitations of the theory
• Explain the key insights of “behavioral finance” along with its critique of traditional
finance
• Articulate the possible explanations for the ongoing turmoil in global financial
markets, including the markets for mortgages, mortgage-backed securities, bonds, and
stocks
