Macroeconomic Analysis with Machine Learning and Big Data

What's New?

July 10: We will have Dr. Jiequn Han to teach a guest lecture on Mean Field Games (MFG) and Heterogeneous Agent Model in Continuous Time (HACT) on July 18.

July 10: The lecture notes on Statistical Model in Macroeconomics (I) taken by @胡裕民 and @杨路 have been uploaded.

July 8: Instructions for the final project have been uploaded here.

July 5: The lecture notes on unsupervised learning taken by @黄冠华 have been uploaded.

July 4: The presentation schedule has been uploaded here. Please refer to the slides of the first lecture for instructions. You can find a sample presentation here, but please note that it was a 15-minute presentation. A 30-minute presentation would have about 20 pages of slides.

July 4: The lecture notes this morning taken by @黄冠华 and @郑重 have been uploaded.

Course Description

We introduce emerging opportunities in macroeconomics due to the recent booming of big data and the development of machine learning. We will systematically discuss relevant existing work (e.g. state space models, heterogeneous agent models, reduced-form macro models) and a series of recent work. The course will be based on lecture notes by instructors and relevant papers.
