What methods can be utilized to resolve endogeneity concerns in econometric models?
Instrumental variable approaches and natural experiments minimize endogeneity in econometric models and improve empirical research study. Endogeneity happens when an independent variable and the mistake term in a regression design are correlated, biassing price quotes. Important variables (IV), which involve recognizing an external variable that is correlated with the endogenous variable however not with the mistake term, are one technique utilized by econometricians to resolve this issue. IVs fix for measurement mistake, left out variables, reverse causality, and endogeneity.

Natural experiments utilize exogenous shocks or quasi-random variation in information to determine causal effects. Natural experiments can result from government policy changes or treatment randomization. These techniques require strong instrument validity presumptions and may not deal with simultaneous equations designs or cointegration tests. Hence, econometricians need to check alternative requirements and carry out level of sensitivity analyses to ensure design robustness.
