Jérémy Fouliard (LBS) – “Answering the Queen : online machine learning and financial crises”, joint work with Hélène Rey (LBS)
Abstract: Predicting systemic financial crises has been elusive. It is however a key input for macroprudential policy. We consider the framework of sequential predictions, also called online machine learning, to predict systemic financial crises in a panel of 7 countries. Since there is no consensus on the origins of financial crises, we optimally aggregate a class of reference forecasters using 4 types of aggregation rules. We can predict crisis periods 3 years in advance out-of-sample with remarkable accuracy. We report for each country the subset of variables that appear the most frequently in our best forecasting models.
