报告摘要：
Researchers often include many covariates in their linear regression models to control for confounders in empirical research in economics, statistics and social sciences. It is also common practice in empirical work to use cluster-robust standard errors. In this project, we develop inference methods that are robust to the presence of many covariates and to clustering. We find that when the number of included covariates grows at the same rate as the sample size, the commonly used Liang-Zeger and HC-k cluster robust standard errors are invalid in general. We propose cluster robust standard error formulas that are robust to the inclusion of possibly many covariates from different approaches and apply the standard errors under different setups. Simulation evidence supporting our theoretical results is also provided.
