Contenu
This course will focus on methods in time series econometrics designed to handle “big data.”
We will talk about univariate predictive regressions with many regressors, discussing various dense and sparse regularization techniques, such as principal components, ridge, lasso and others. We will discuss Bayesian inference in the context of these regressions and explore the connection between Bayesian shrinkage and regularization.
The course will then cover some of the most popular multivariate econometric models for big data. We will talk about dynamic factor models, looking at different estimation techniques, including Bayesian. The course will also cover Bayesian VARs, detailing in particular how they can be used to deal with mixed-frequency and irregularly sampled data. We will discuss applications of these models and methods to nowcasting and forecasting in macroeconomics and finance.
We will also touch on machine learning for macroeconomic forecasting, if time permits.

Méthodes d'enseignement
This is an advanced course based mostly on the papers listed below. Students are expected to engage actively in the class, read the material ahead and participate in discussions.
The expectation is that the class will be taught in person, subject to the evolving situation with Covid-19.

Modes d'évaluation

des acquis des étudiants
For the evaluation students will prepare and present in class an extended "discussion" of a relevant paper to be chosen in agreement with the teacher of the course. The final grade is awarded based on the presentation.
What does "discussion" mean exactly? Academic conferences often feature a discussant, who speaks after the presenter of a paper. They generally summarise the paper and provide in depth comments on the paper being presented, highlighting the key contributions as well as the drawbacks and issues with the paper.
