In this article, we propose a statistical model for the purpose of identifying a subgroup that
has an enhanced treatment effect as well as the variables that are predictive of the subgroup …

We provide a solution to the informed-principal problem in the independent private values
setting with monetary transfers. The principal's private information creates signaling …

Markov regime-switching models are very common in economics and finance. Despite
persisting interest in them, the asymptotic distributions of likelihood ratio-based tests for …

Empirical evidence suggests that workers care about the mission of their job, in addition to
their wage. This paper studies how organizations can choose a mission to attract …

Testing for regime switching when the regime switching probabilities are specified either as
constants ('mixture models') or are governed by a finite-state Markov chain ('Markov …

We study the econometrics of an asymmetric Tullock contest model with incomplete
information. Identification results are established for parameters in the asymmetric contest …

We show that, in environments with independent private values and transferable utility, a
privately informed principal can implement a contract that is ex-ante optimal for her. As an …

This paper develops the likelihood ratio-based test of the null hypothesis of a M0-component
model against an alternative of (M0+ 1)-component model in the normal mixture panel …
