New Text data is inherently high-dimensional, which makes machine learning regularization techniques natural tools for its analysis. In a new paper with Bryan Kelly and Alan Moreira, we develop an economically-motivated high dimensional selection model that can improve machine learning from text in particular and from sparse counts data more generally. We apply this framework to backfill central financial variables to historical periods using newspaper coverage, and find that it substantially improves out-of-sample fit relative to alternative state-of-the-art approaches.

New How much would investors pay to receive investment-relevant information? In a paper coauthored with Ohad Kadan forthcoming at RFS, we derive a general expression for the value of information to a price-taking investor in a dynamic environment and provide a framework for its estimation. To illustrate, we estimate values of leading macroeconomic indicators (GDP, employment, etc.) and rank them. Using variations in option prices we find that a consumer-investor with conventional preference parameters would pay 3 to 5 basis points of her wealth for a one-time private peek into these indicators.

New Hub-and-spoke regulation, where a central regulator with legal power over firms delegates monitoring to local supervisors, can improve information collection, but can also lead to agency problems and capture. In a new paper with Yadav Gopalan and Ankit Kalda, we document that following the closure of a US bank regulator's field offices, the banks they previously supervised distribute cash, increase leverage, and increase their risk of failure, more than similar banks in the same time and place.
