I am a Ph.D. student in Economics at NYU. Recently, I have been working with machine learning and economic forecasting, but I am interested in Econometrics as a broad field.

Estimation of Multi-Unit Double Auctions (Link)
Estimating market power is an essential, if not complicated, task for market designers. This is rendered even harder when there are few sellers and few buyers in a given market. This research aims to allow for the distinction of market power from both the demand and supply sides simultaneously. I propose a bootstrap-based procedure to estimate multi-unit, two-sided auctions in which all agents can submit elastic price schedules. I use this methodology to estimate the private values of all agents in the Italian electricity market. The results suggest that buyers and sellers both have market power. An earlier version of this paper was awarded a student research prize and this paper is being expanded with Quang Vuong.
Solving and Estimating Finite-Time, Dynamic Discrete Choice Models with Deep Learning (Link)
Empirical evidence shows that deep learning performs well in situations where the curse of dimensionality is computationally prohibitive. This situation is common when solving finite-time, dynamic discrete choice models because they feature infinite dimension state-space, and also because of the nonstationary nature of these problems. I show how to approximate policy functions of those models with deep neural networks. These methods reduce the complexity of the problem, simplifying the computation process when closed-form solutions are not available.
