How can we control for latent discrimination in predictive models? How can we provably remove it? Such questions are at the heart of algorithmic fairness and its impacts on society. In this paper, we define a new operational fairness criteria, inspired by the well-understood notion of omitted...

This paper develops a strategy with simple implementation and limited data requirements to identify spatial distortion of supply from demand – or, equivalently, unequal access to supply among regions – in transportation markets. We apply our method to ride-level, multi-platform data from New...

Reclassification risk is a major concern in health insurance where contracts are typically one year in length but health shocks often persist for much longer. We use rich individual-level medical information from the Utah all-payer claims database to empirically study one possible solution:...

In vertical markets, eliminating double marginalization with a two-part tariff may not be possible due to downstream firms' risk aversion. When demand is uncertain, contracts with large fixed fees expose the downstream rm to more risk than contracts that are more reliant on variable fees. In...

Reclassification risk is a major concern in health insurance where contracts are typically one year in length but health shocks often persist for much longer. While most health systems with private insurers emphasize short-run contracts paired with substantial pricing regulations to reduce...

This paper develops a model of vertical markets with multiple upstream and downstream firms. Networks of vertical relationships, negotiated contract terms for those relationships, and downstream prices charged to end customers all arise endogenously. In addition, I provide an estimation...

We build a structural econometric model of pricing substitutes with menu costs and apply it to quasi-experimental data to estimate the share of physical menu costs (material and labor costs of price adjustment) in total menu costs. The data comes from the adoption of electronic shelf labels...
