Intended Learning Outcomes (ILO)
KNOWLEDGE AND UNDERSTANDING
The objective of this course is to introduce the main econometric methods and techniques used in empirical finance. This is an ambitious task that brings together different type of knowledge: finance theory, statistics, programming. You learn how to use software, in particular the R software, to specify, estimate and simulate model of financial data to be used for asset allocation, risk measurement and risk management. The teaching strategy is based on providing inputs to students that are supposed to active elaborate them to produce their knowledge. The choice of inputs and the mapping of inputs into knowledge is the students’ responsibility. The course is designed to give opportunities. The decision of how many opportunities to take and how to take them is left to course participants.
APPLYING KNOWLEDGE AND UNDERSTANDING
 Apply econometric techniques to assset allocation and risk measurement.
Teaching methods
 Facetoface lectures
 Exercises (exercises, database, software etc.)
DETAILS
The main inputs provided to the students are references, slides, notes, draft R codes and exercises designed to provide challenges that stimulate learning. The empirical applications are based on databases freely available on the web. Students are expected to download and install the R and Rstudio packages on their PC at the beginning of the course.
Assessment methods
Continuous assessment  Partial exams  General exam
