### Compétences à acquérir

Students will be provided with the key insights of theoretical models to understand why decisions such as full versus partial insurance are taken. The overview of the basic models of investors’ behaviour shall also provide students with a fundamental knowledge of investment theory.At the end of the course students should be able to compare investments in different assets by evaluating the expected return to maturity and to calculate the return and variance of a portfolio. This knowledge should help the reading of the financial press and should make students aware that the ability of a successful financial advisor stems from understanding the underlying theoretical concepts of investment decisions.

### Description du contenu de l'enseignement

The aim of the course is to learn the key tools and concepts to analyse how decision makers choose from a set of feasible alternatives when the consequences or outcomes are uncertain. These analytical tools are then applied to real-life economic and financial decisions, like the purchase of insurance and the trading of financial assets in financial markets, to gain some insights on how those markets work.The course focuses on insurance and financial investment decisions. The decision of full insurance is compared to the decision of partial insurance and the conditions for the optimality of the two are considered, under both symmetric and asymmetric information.

After reviewing the types of financial markets and the types of assets traded, the course considers the measurement of return and risk of single assets and of a portfolio.

The Markowitz model is presented to illustrate how single investors choose their optimal portfolio.
