Many economic panel and dynamic models, such as rational behavior and Euler equations, imply that the […]
We introduce a novel framework for individual-level welfare analysis. It builds on a parametric model for […]
The persuasion rate is a key parameter for measuring the causal effect of a directional message […]
Multivalued treatments are commonplace in applications. We explore the use of discrete-valued instruments to control for […]
This paper examines a commonly used measure of persuasion whose precise interpretation has been obscure in […]

We provide novel bounds on average treatment effects (on the treated) that are valid under an […]
This paper describes three methods for carrying out non-asymptotic inference on partially identified parameters that are […]

In this paper, we estimate the time-varying COVID-19 contact rate of a Susceptible-Infected-Recovered (SIR) model. Our […]
We investigate state-dependent effects of fiscal multipliers and allow for endogenous sample splitting to determine whether […]
We consider both l0-penalized and l0-constrained quantile regression estimators. For the l0-penalized estimator, we derive an […]
