Text As Data in Economics

Applied Machine Learning and Big Data Analysis - MSc in Advanced Economics - ENS de Lyon

This website gathers resources for the two 3h-lectures on Text As Data in Economics of the Applied Machine Learning and Big Data Analysis as part of the MSc in Advanced Economics at ENS de Lyon.

Text data are ubiquitous. Recent methodological and technological developments now allow to study these data systematically, enabling economists to investigate new questions and to quantify concepts that were previously difficult to measure.

This course thus aims to provide an overview and understanding of:

• Why text data is useful in economics research and what research questions it enables to address
• A typical empirical workflow for text analysis
• How to concretely implement these analyses in Python
• An overview of the recent developments in the field
• How this section relates to the rest of the class
