Jackknife Instrumental Variable Inference
Federico Crudu, Giovanni Mellace, Zsolt Sándor
This paper introduces a class of jackknife-based test statistics for linear regression models with endogeneity and heteroskedasticity in the presence of many potentially weak instr…
On the Role of the Zero Conditional Mean Assumption for Causal Inference in Linear Models
Federico Crudu, Michael C. Knaus, Giovanni Mellace +1
Many econometrics textbooks imply that under mean independence of the regressors and the error term, the OLS parameters have a causal interpretation. We show that even when this as…
Bilinear form test statistics for extremum estimation
Federico Crudu, Felipe Osorio
This paper develops a set of test statistics based on bilinear forms in the context of the extremum estimation framework with particular interest in nonlinear hypothesis. We show t…
