This project adapts online learning techniques to unstructured data, focusing on neural networks. We posit a non-parametric multi-armed bandit algorithm with context that uses a neural network for its underlying function approximation. We theoretically analyze and prove guarantees on the regret under this algorithm Read More

Globally, 1.5 billion people live off the grid, their only access to electricity often limited to operationally-expensive fossil fuel generators. Solar power has risen as a sustainable and less expensive option, but its generation is variable during the day and non-existent at night. Read More

I quantify the impact of trade secret protection on labor outsourcing, and consequently, on aggregate productivity. Read More

We show that financial reporting spurs consumer behavior. Using granular GPS data, we show that foot-traffic to firms’ commerce locations significantly increases in the days following their earnings announcements. Read More
