A Price Theory of Multi-Sided Platforms
I develop a general theory of monopoly pricing of networks. Platforms use insulating tariffs to avoid coordination failure, implementing any desired allocation. Profit-maximization distorts in the… Expand
Stability and Competitive Equilibrium in Trading Networks
We introduce a model in which agents in a network can trade via bilateral contracts. We find that when continuous transfers are allowed and utilities are quasi-linear, the full substitutability of… Expand
Matching in Networks with Bilateral Contracts
We introduce a model in which firms trade goods via bilateral contracts which specify a buyer, a seller, and the terms of the exchange. This setting subsumes (many-to-many) matching with contracts,… Expand
Patent Trolls: Evidence from Targeted Firms
We develop a theoretical model of, and provide the first large-sample evidence on, the behavior and impact of non-practicing entities (NPEs) in the intellectual property space. Our model shows that… Expand
A Theory of Intergenerational Mobility
We study the link between market forces, cross-sectional inequality, and intergenerational mobility. Emphasizing complementarities in the production of human capital, we show that wealthy parents… Expand
To Groupon or not to Groupon: The profitability of deep discounts
We examine the profitability and implications of online discount vouchers, a relatively new marketing tool that offers consumers large discounts when they prepay for participating firms’ goods and… Expand
Big Data and Big Cities: The Promises and Limitations of Improved Measures of Urban Life
New, “big” data sources allow measurement of city characteristics and outcome variables higher frequencies and finer geographic scales than ever before. However, big data will not solve large urban… Expand

We show that in the presence of admissions reserves, the effect of the precedence order (i.e., the order in which different types of seats are filled) is comparable to the effect of adjusting reserve… Expand
To Groupon or Not to Groupon: The Profitability of Deep Discounts
We examine the profitability and implications of online discount vouchers, a relatively new marketing tool that offers consumers large discounts when they prepay for participating firms' goods and… Expand
Strategy-proofness, investment efficiency, and marginal returns: an equivalence
TLDR
It is shown that under the Kelso--Crawford (1982) worker-optimal stable mechanism (with discrete transfers), workers are incentivized to make approximately efficient human capital investments before entering the labor market (conditional on the actions of firms). Expand
