Stretching the Net: Multidimensional Regularization (Econometric Theory, 2021)


"Stretching the Net: Multidimensional Regularization", forthcoming at Econometric Theory


In the paper I derive asymptotic risk (expected loss) results for shrinkage estimators with multidimensional regularization in high-dimensional settings.

I show that as the number of parameters to estimate grows the empirical loss converges to the oracle-optimal risk.

"Predictor selection for synthetic controls." arxiv

This paper proposes the use of a sparse synthetic control procedure that penalizes the number of predictors used in generating the counterfactual to select the most important predictors. We derive, in a linear factor model framework, a new model selection consistency result and show that the penalized procedure has a faster mean squared error convergence rate.
