One of the most exciting recent developments in financial research is the availability of new administrative, private sector and micro-level datasets that did not exist a few years ago. The unstructured nature of many of these observations, along with the complexity of the phenomena they measure, means that many of these datasets are beyond the grasp of econometric analysis. Machine learning (ML) techniques offer the numerical power and functional flexibility needed to identify complex patterns in a high-dimensional space. However, ML is often perceived as a black box, in contrast with the transparency of econometric approaches. This article demonstrates that each analytical step of the econometric process has a homologous step in ML analyses. By clearly stating this correspondence, our goal is to facilitate and reconcile the adoption of ML techniques among econometricians.
