Propensity
Score Methods for Causal Inference in Experimental and Observational
Studies: This research program generalizes and improves
propensity score methods, which allow researchers to obtain reliable
estimates of causal effects in a variety of settings. Supported by
the NSF grant, SES-0550873. |
Matching
Methods for Causal Inference in Experimental and Observational
Studies: This research program develops various
matching methods, which allow researchers to compare units that are
similar to each other except for the key causal variables of
interest. Supported by the NSF grant, SES-0550873. |
Design and
Analysis of Randomized Experiments and Program
Evaluation: This research program develops
statistical tools for efficiently designing and analyzing
randomized experiments in political science and public policy.
Supported by the NSF grant, SES-0752050. |
Identification of Causal
Mechanisms via Causal Mediation Analysis:
This research program develops statistical analysis and
research design strategies for identifying causal
mechanisms in addition to causal effects. Supported by
the NSF grant, SES--0918968. |
Elicitation of Truthful Answers to
Sensitive Survey Questions: This research program
develops new statistical models to analyze survey experiments for
eliciting truthful answers to sensitive questions such as racial
prejudice and support for militant groups. Supported by the NSF
grant, SES-0849715 and the IGC grant, RA-2010-12-013. |
