2023 Denis Sargan Econometrics Prize

Denis Sargan EctJ Prize v4-01

The RES is pleased to announce that the 2023 Denis Sargan Econometrics Prize has been awarded to Alexander Kreiss (Leipzig University) for the article ‘Inference in regression discontinuity designs with high-dimensional covariates,’ with Christoph Rothe (University of Mannheim).

The prize-winning paper was published in the May 2023 issue of The Econometrics Journal. You can read the full article Free to View here.

The Prize was awarded for the following reasons:

  • The article considers the extension of the local linear regression-discontinuity estimator to high-dimensional settings, in which the number of covariates may increase with the sample size.
  • To this end, it proposes to first select a small number of covariates using a lasso variant of the standard local linear regression-discontinuity estimator and then apply the standard estimator with only the selected covariates.
  • It demonstrates that, under an assumption that only a small number of covariates is particularly important (‘approximate sparsity’), this two-step estimator has asymptotic properties that are similar to those of the standard estimator in the low-dimensional case.
  • It demonstrates its implementation and practical usefulness in simulations and an empirical application.

The 2023 Denis Sargan Econometrics Prize winner Alexander Kreiss said:

“The award of the Sargan Prize came as a complete surprise to me. Having our work recognized in this way is a great motivation for my future scientific projects, in particular for challenging projects with unknown outcomes which require a lot of effort. I am very grateful to the RES and The Econometrics Journal for awarding the prize and publishing our work. I am also grateful to Christoph Rothe who introduced me to causal inference using Regression Discontinuity Designs and who initiated this project on high-dimensional covariates in such models.”

The Prize is awarded for the best unsolicited article published in The Econometrics Journal in a given year by anyone who is within five years of having received their doctorate. The Prize may be awarded for articles coauthored with senior researchers, provided that the junior author(s) contributed at least equally. In those cases, the Prize is only given to the eligible, junior author(s).

The  2023 Denis Sargan Econometrics Prize will be presented to Alexander Kreiss on 26 March at the gala dinner of the annual Royal Economic Society Conference in Belfast.
