Query: Estimating Heterogeneous Causal Effects of High-Dimensional Treatments:
  Application to Conjoint Analysis   Estimation of heterogeneous treatment effects is an active area of research
in causal inference. Most of the existing methods, however, focus on estimating
the conditional average treatment effects of a single, binary treatment given a
set of pre-treatment covariates. In this paper, we propose a method to estimate
the heterogeneous causal effects of high-dimensional treatments, which poses
unique challenges in terms of estimation and interpretation. The proposed
approach is based on a Bayesian mixture of regularized regressions to identify
groups of units who exhibit similar patterns of treatment effects. By directly
modeling cluster membership with covariates, the proposed methodology allows
one to explore the unit characteristics that are associated with different
patterns of treatment effects. Our motivating application is conjoint analysis,
which is a popular survey experiment in social science and marketing research
and is based on a high-dimensional factorial design. We apply the proposed
methodology to the conjoint data, where survey respondents are asked to select
one of two immigrant profiles with randomly selected attributes. We find that a
group of respondents with a relatively high degree of prejudice appears to
discriminate against immigrants from non-European countries like Iraq. An
open-source software package is available for implementing the proposed
methodology.
