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 CWP32/20
In this paper, we estimate the time-varying COVID-19 contact rate of a Susceptible-Infected-Recovered (SIR) model.
Cemmap Working Paper CWP30/20
We consider both l0-penalized and l0-constrained quantile regression estimators.

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.

We consider both l0-penalized and l0-constrained quantile regression estimators.

We investigate state-dependent effects of fiscal multipliers and allow for endogenous sample splitting to determine whether the US economy is in a slack state.

Cemmap Working Paper CWP19/20
We investigate identification of causal parameters in case-control and related studies.
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.
Journal article
We compare two groups of the non-student Korean population—native-born South Koreans (SK) and North Korean refugees (NK)—with contrasting institutional and cultural backgrounds. In our experiment, the subjects play dictator games under three different treatments in which the income source ...
Cemmap Working Paper CWP69/19
We set up an econometric model of persuasion and study identification of key parameters under various scenarios of data availability.
