Elite economics PhD programs aim to train graduate students for a lifetime of academic research. This paper asks how advising affects graduate students' post-PhD research productivity. Advising is highly concentrated: at the eight highly-selective schools in our study, a minority of advisors do...

We develop and estimate a model of consumer search with spatial learning. Consumers make inferences from previously searched objects to unsearched objects that are nearby in attribute space, generating path dependence in search sequences. The estimated model rationalizes patterns in data on...

We study the propagation of nominal shocks in a dispersed information economy where firms learn from and respond to … information generated by their activities in product and factor markets. We prove the existence of a "Hayekian benchmark", defined … by conditions under which imperfect information has no effect on equilibrium outcomes. This occurs under fairly general …

What do machines learn, and why? To answer these questions we import models of human cognition into machine learning. We propose two ways of modeling machine learners based on this join: feasibility-based and cost-based machine learning. We evaluate and estimate our models using a deep learning...

Economics has long studied how consumers respond to the disclosure of information about firms. We study a case in which … the disclosed information is unrelated to the product or firm leadership, but which could still potentially affect … consumer patronage through the mechanism of repugnance, as described in Roth (2007). The information in this case concerns the …

Spending induced by health insurance is often called moral hazard and definitionally assumed to be inefficient. We adapt standard models and show that for those living "hand-to-mouth", the financing benefits of insurance cause a portion of moral hazard to be efficient. Although insurance's price...
