The first part of the course aims to provide a good knowledge of the core principles and topics of modern asset pricing theory. It presents key concepts, relations, and models of asset pricing to develop a sound understanding of the pricing of financial assets under realistic conditions of a multiperiod stochastic environment with incomplete markets. The Asset Pricing module covers various theories from the Stochastic Discount Factor Theory to the Consumption Capital Asset Pricing Model and discusses practical issues such as the equity premium puzzle. The second part of the course aims to provide the students with the basic principles of modern contract theory. The main concepts are discussed within a unified framework. After having introduced the basic model of symmetric information, the case of asymmetric information is discussed, in relation with the problems of moral hazard, adverse selection and signaling. The analytical tools developed are then used to analyze issues related to credit and insurance markets.
The course is in two parts: Financial Contracts and Asset Pricing. Please see the corresponding programs
Decision Theory and Behavioural Economics
Prerequisiti e modalità di esame
For the Financial Contracts model: Written exam (approximately 1 hour). The exam covers all the topics presented during lectures and it consists of a series of questions and exercises. The exam aims to verify that the course objectives have been achieved, that is: students have learnt the economic intuition of the models presented in the lectures and are able to apply the key concepts to practical cases.
For the Asset Pricing module: Written exam (approximately 1 hour and 30 minutes). The exam covers all the topics presented during lectures and it consists of a series of open-ended questions which may include calculations and/or explanation and/or technical analysis. The exam aims to verify that the course objectives have been achieved; i.e. that students have learned the theory, and know how to use it to explain price differences between different assets, and their determinants.
