Residential Segregation and the Demand for Schooling
Job Market Paper
This paper studies how schools affect where families choose to live. Using administrative data from New Zealand, I estimate a dynamic model of residential choice and benchmark the results against the standard reduced form approach. In a simplified counterfactual, I show that schools reduce segregation in part because families experience a disutility of changing schools when moving houses.

What Drives the Efficiency in Ridesharing Markets?
with Vinayak Iyer
This paper studies a ridesharing company in Austin, Texas to understand how centralized dispatching and dynamic (surge) pricing improve upon traditional taxicabs. We show how existing inefficiencies in a decentralized transportation market are solved by these two features and evaluate alternate pricing and matching rules that can improve outcomes.

Lunches for Loyalty: The Effect of Direct-to-Physician Advertising in New Drug Markets
I study how pharmaceutical companies advertise to physicians when releasing products in a new drug class. This is relevant for two reasons. First, physician detailing is primarily concentrated in newer drugs. Second, there is large uncertainty regarding the efficacy of newer drugs, leaving potentially large scope for influencing physician prescribing behavior. I focus on the case of a novel class of anti-diabetic medications, which experienced a gradual introduction of new products and information shocks to our understanding of their risks and efficacy.
Cutoff from Support: The Effects of Losing Cash Welfare
with Lucas Husted
We evaluate a policy reform in Michigan, which unexpectedly removed over 16,000 families from TANF. Using a difference-in-difference framework, we find families affected increase their employment, but become poorer as they are unable to offset the loss of welfare benefits.
The Efficiency Effects of Drug Acquisitions from Access to Sales Representatives
with Kritika Goel
We document novel evidence on an important source of efficiency from drug acquisitions: access to the marketing networks of an acquiring firm. We focus on 13 drug acquisitions by 11 firms in 2015-2016. Using transaction-level data on physician detailing, we document patterns in the data consistent with the presence of efficiencies in network size.
