Abstract-We study employers’ perceptions of postsecondary degrees using a field experiment. We randomly assign the sector and selectivity of institution to fictitious resumes and send them to real vacancy postings on a large online job board. According...

Abstract-In online social networks such as Facebook or Twitter users can advertise products and services by using appropriate labels to convey the content...
Abstract:We propose solutions to two important problems that have received relatively little attention in the field of survey weighting: the construction of population targets in the face of irregularly missing data, and the optimal selection of...
Abstract-In a field experiment in Uganda, we find that demand after a free distribution of three health products is lower than after a sale distribution. This contrasts with earlier work on insecticide-treated bednets, highlighting the importance of...
Abstract:We show that central limit theorems hold for high-dimensional normalized means hitting high-dimensional rectangles. These results apply even when p>> n. These theorems provide Gaussian distributional approximations that are not pivotal, but they...

Abstract: Social and medical scientists are often concerned that the external validity of experimental results may be compromised because of heterogeneous treatment effects. If a...
Abstract: Researchers and policy makers are often interested in estimating how treatments or policy interventions affect the outcomes of those most in need of help. This concern has motivated the increasingly common practice of disaggregating experimental...
Abstract: The microbial communities, or microbiomes, residing in the mammalian gut are inherently dynamic, changing due to many factors including host maturation, alteration of the diet, and exchange of microbes with the environment or other hosts. Recent...
Abstract: Advances in high-throughput laboratory and health information technologies are revolutionizing the disciplines of pathology and laboratory medicine. The ability to extract clinically actionable knowledge using computational methods from complex...
