This paper studies difference-in-differences (DiD) setups with repeated cross-sectional data
and potential compositional changes across time periods. We begin our analysis by deriving …

This study considers various semiparametric difference-in-differences models under
different assumptions on the relation between the treatment group identifier, time and …

This article considers a Mann–Whitney test of distributional effects in a multivalued
treatment. Specifically, we first show that, under the unconfoundedness condition, the …

In many observational studies, the treatment assignment mechanism is not individualistic, as
it allows the probability of treatment of a unit to depend on quantities beyond the unit's …

Propensity score matching (PSM) is a pseudo-experimental method that uses statistical
techniques to construct an artificial control group by matching each treated unit with one or …

Partial mean with generated regressors arises in several econometric problems, such as the
distribution of potential outcomes with continuous treatments and the quantile structural …

Semiparametric efficient estimation of various multi-valued causal effects, including quantile
treatment effects, is important in economic, biomedical, and other social sciences. Under the …

This paper provides evidence on the likelihood of formal finance usage among innovative
small and medium enterprises (SMEs) operating in ASEAN countries. To this end, the SMEs …

This article provides a general estimation and inference framework to study how different
levels of program participation affect participants' outcomes. We decompose differences in …

In experimental design and causal inference, it may happen that the treatment is not defined
on individual experimental units, but rather on pairs or, more generally, on groups of units …
