Asymptotic Bias of OLS in the Presence of Reverse Causality
نویسنده
چکیده
In this paper, I derive an expression for the asymptotic bias in the OLS estimator of the partial effect of a regressor on the dependent variable when there is reverse causality and all variables in the model are covariance stationary. I show that the sign of the asymptotic bias depends only on the signs of the bi-directional causal effects. JEL Codes: C10, C30.

A Note on Parametric and Nonparametric Regression in the Presence of Endogenous Control Variables
A Note on Parametric and Nonparametric Regression in the Presence of Endogenous Control Variables This note argues that nonparametric regression not only relaxes functional form assumptions vis-a-vis parametric regression, but that it also permits endogenous control variables. To control for selection bias or to make an exclusion restriction in instrumental variables regression valid, additiona...
متن کاملBias and MSE Analysis of the IV Estimator Under Weak Identification with Application to Bias Correction∗
We provide results on properties of the IV estimator in the presence of weak instruments, beginning with the derivation of analytical formulae for the asymptotic bias (ABIAS) and mean squared error (AMSE). We also obtain approximations for the ABIAS and AMSE formulae based on an asymptotic scheme; which, loosely speaking, requires the expectation of the first stage F-statistic to converge to a ...
متن کاملBank Lending Behaviour over the Business Cycle in Iran
This paper studies bank loans over the business cycles in Iran to determine the role of Iranian banks in stabilizing credit. By estimating the long-run relations using dynamic OLS and fully modified OLS estimators, the findings show that real bank lending is positively related to real GDP in the long-run providing evidences of the pro-cyclicality of bank lending in Iran. Hence, Iranian banking ...
متن کاملIV estimation with valid and invalid instruments
While 2SLS is the most widely used estimator for simuhaneous equation models, OLS may do better in finite samples. Here we demonstrate analytically that the for the widely used simultaneous equation model with one jointly endogenous variable and valid instruments, 2SLS has smaller MSE error, up to second order, than OLS unless the R , or the F statistic of the reduced form equation is extremely...
متن کاملIntegrated Modied OLS Estimation and Fixed-b Inference for Cointegrating Regressions
This paper is concerned with parameter estimation and inference in a cointegrating regression, where as usual endogenous regressors as well as serially correlated errors are considered. We propose a simple, new estimation method based on an augmented partial sum (integration) transformation of the regression model. The new estimator is labelled Integrated Modi ed Ordinary Least Squares (IM-OLS)...
