Presenter: Jelani Nelson- Dimensionality Reduction Via Sparse Matrices

January 28, 2015

|

12:00PM - 1:30PM EST

Presenter: Jelani Nelson Abstract: This talk will discuss sparse Johnson-Lindenstrauss transforms, i.e. sparse linear maps into much lower dimension which preserve the Euclidean geometry of a set of vectors. Both upper and lower bounds will be presented...

Presenter: David Deming- The Value of Postsecondary Credentials in the Labor Market: An Experimental Study

December 3, 2014

|

12:00PM - 1:30PM EST

Presenter: David Deming 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...

Presenter- Devin Caughey- Bayesian Population Interpolation and Lasso-Based Target Selection in Survey Weighting

November 5, 2014

|

12:00PM - 1:30PM EST

Presenter: Devin Caughey 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...

Presenter- Margaret McConnell- To Charge or Not to Charge: Evidence from a Health Products Experiment in Uganda

October 29, 2014

|

12:00PM - 1:30PM EDT

Presenter: Margaret McConnell 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...

Presenter- Victor Chernozhukov- Gaussian Approximations, Bootstrap, and Z-estimators when p >> n

October 22, 2014

|

12:00PM - 1:30PM EDT

Author: Victor Chernozhukov 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...

Presenter Teppei Yamamoto- Design, Identification, and Sensitivity Analysis for Patient Preference Trials

12:00PM - 1:30PM EDT

Authors: Dean Knox, Teppei Yamamoto, Matthew A. Baum, and Adam Berinsky 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...
