This paper studies measuring the average effects ß of X on Y in a structural system with random coeffi cients and confounding. We do not require (conditionally) exogenous regressors …
economics.ucr.edu/wp-content/uploads/2019/10/Chalak-paper-for-10...PDFThe method of indirect least squares (ILS) using a proxy for a discrete instrument is shown to identify a weighted average of local treatment effects. The weights are nonnegative if and …
This paper demonstrates the extensive scope of an alternative to standard instrumental variables methods, namely covariate&based methods, for identifying and es& timating effects of …
www.kchalak.com/s/Identification-with-Conditioning-Instruments...PDFWe study the structural identification of causal effects with conditioning instruments within the settable system framework. In particular, we provide causal and predictive conditions …
This note examines the robustness of two quantile treatment effect estimands to a perturbation away from the common effect assumption. The first estimand Q Y 1 − Y 0 ( τ ) is the τ -…
Endogeneity and simultaneity have been at the heart of econometrics since the 1930’s–40’s.“Simultaneity” refers to the case in which the econometric model simultaneously determines …
Local governments often seek credit ratings from multiple agencies for external financing. Rating shopping and catering, the incentives of the rating agencies, and the career incentives …
The Gini-Frisch bounds partially identify the constant slope coefficient in a linear equation when the explanatory variable suffers from classical measurement error. This paper …
