Option à 2+2 ECTS

Summary: This course will present the different types of financial crises and bubbles on financial markets, and the theoretical and empirical around them, to better understand the triggers and consequences of financial crises. The class will help understand how financial analysts assess the evolution of certain asset prices, create specific indicators as early warnings of potential crises, as well as the actual and possible regulatory responses. It will also present recent financial innovations and question their impact on financial stability.

The goal of the class will be to use those analytical tools to be able to assess, like professional analysts, recent market events or chosen examples. Each class will develop a skill that will be use in the final analytical paper, where each student will choose among recent questions linked to market evolution, how to answer professionally and clearly.

Skills to develop:

• Problematize an economic question on recent financial markets evolution and contextualize it socially, historically and within the academic literature.
• Think like an economist to reach a deeper understanding of how a financial innovation can impact the financial system as a whole and evaluate potential solutions/regulation if needed.
• Learn how to use evidence, in combination with economic theory and research design, to ask questions about how data change your understanding of the issue at stake.
• Analyze multi-dimensional economic datasets and present descriptive statistics them clearly.
• Communicate professionally on a research outcome in front of various audiences.
