Journal articles

Journal article | Economic Inquiry
We investigate state‐dependent effects of fiscal multipliers and allow for endogenous sample splitting to determine whether the U.S. economy is in a slack state.
Journal article
This paper studies inference of preference parameters in semiparametric discrete choice models when these parameters are not point-identified and the identified set is characterized by a class of conditional moment inequalities.

Working papers

Cemmap Working Paper CWP43/21
We provide novel bounds on average treatment effects (on the treated) that are valid under an unconfoundedness assumption.
Cemmap Working Paper CWP33/21
This paper describes three methods for carrying out non-asymptotic inference on partially identified parameters that are solutions to a class of optimization problems.

In this paper, we estimate the time-varying COVID-19 contact rate of a Susceptible-Infected-Recovered (SIR) model.
Cemmap Working Paper CWP31/20
We investigate whether growing up in a socialist country affects the development of competitiveness by comparing three Korean groups in South Korea, born and raised in three countries with distinct institutional environments: South Korea, North Korea, and China.
Cemmap Working Paper CWP30/20
We consider both l0-penalized and l0-constrained quantile regression estimators.

Cemmap Working Paper CWP18/20
Datasets that are terabytes in size are increasingly common, but computer bottlenecks often frustrate a complete analysis of the data.
Cemmap Working Paper CWP19/20
We investigate identification of causal parameters in case-control and related studies.
