Inference in linear regression models with many covariates and heteroskedasticity

Cattaneo, Matias D.; Jansson, Michael; Newey, Whitney K. - 2017

The linear regression model is widely used in empirical work in Economics, Statistics, and many other disciplines …. Researchers often include many covariates in their linear model specification in an attempt to control for confounders. We give … inference methods that allow for many covariates and heteroskedasticity. Our results are obtained using high …

Matchings with lower quotas: Algorithms and complexity

Arulselvan, Ashwin; Cseh, Ágnes; Groß, Martin; … - 2017

We study a natural generalization of the maximum weight many-to-one matching problem. We are given an undirected … maximum weight many-to-one matching satisfying two sets of constraints: vertices in A are incident to at most one matching … upper quota. This problem, which we call maximum weight many-to-one matching with lower and upper quotas (WMLQ), has …
