摘要：We propose a multiplicity-robust estimation method for static or dynamic games. The method allows for distinct behaviors and strategies across markets by treating market-specific behaviors as correlated latent variables, with their conditional probability measure treated as an infinite-dimensional nuisance parameter. Instead of solving the intermediate infinite-dimensional optimization problem, we consider the equivalent finite-dimensional dual problem. This property allows for a practically f...

摘要：This article studies an insurance market on which privately informed consumers can simultaneously trade with several firms operating under a regulation that prohibits cross-subsidies between contracts. The regulated game supports a single equilibrium allocation in which each layer of coverage is fairly priced given the consumer types who purchase it. This competitive allocation cannot be Pareto-improved by a social planner who observes neither consumers' types nor their trades with firms. Publ...

摘要：In lower-income countries, the economic contractions that accompany lockdowns to contain COVID-19 transmission can increase child mortality, counteracting the mortality reductions achieved by the lockdown. To formalize and quantify this effect, we build a macrosusceptible-infected-recovered model that features heterogeneous agents and a country-group-specific relationship between economic downturns and child mortality and calibrate it to data for 85 countries across all income levels. We find ...

摘要：This article develops and estimates a dynamic oligopoly model to study the multilevel adoption of electronic medical records in U.S. hospitals. I find substantial competitive effects in the adoption process, and hospitals of the same adoption level compete more intensely than hospitals of different levels do. Counterfactual experiments suggest that competitive effects prompt hospitals to engage in preemptive adoption and greatly deter the second adopter in a duopoly market. By evaluating the g...
