Applied Machine Learning in Economics and Finance (Seminar)

Modern empirical research in economics and finance uses computer intensive methods for the analysis of complex data sets. The estimates are based on algorithmic methods to cope with a whopping number of covariates and possible model specifications. The problem is prevalent e.g., in macroeconomic forecasting, in asset pricing and portfolio selection, and in the evaluation of causal treatment effects of public policies. Consequently, empirical studies in economics and finance rely more and more on machine learning techniques (e.g., lassoing, support vector machines, artificial neuronal nets).

The goal of this seminar is to acquaint students with the necessary toolbox of machine learning techniques. Students must write an empirical research paper in which a novel and/or advanced ML method is applied to shed more light on a real-world problem.

Time and Date

The seminar will take place as a block seminar on the following two days:

  • April 5-6, 2022, 08:15 – 18:00 in room D406

Prerequisites

Econometrics I and Advanced Econometrics (or equivalent). Participation in the courses Financial Econometrics and/or Topics in Advanced Econometrics is an advantage but not a prerequisite. We expect that students have a decent programming background in either MatLab, R or Python or at least willing to invest sufficient effort to learn one of these languages.
