forward, backward, and stepwise confounding variable selection estimate the ATE compared to spike-and-slab Bayesian variable …. Overall, results suggest that Bayesian variable selection is more appealing in smaller sample sizes than frequentist variable …

We ask whether Bayesian estimation creates a potential estimation bias as compared with standard estimation techniques … treat each in turn as the true model and create Bayesian estimates of it under priors from the true model and its false … alternative. The Bayesian estimation of macro models may thus give very misleading results by placing too much weight on prior …

This paper studies semiparametric versions of the classical sample selection model (Heckman (1976, 1979)) without exclusion restrictions. We extend the analysis in Honor'e and Hu (2020) by allowing for parameter heterogeneity and derive implications of this model. We also consider models that...

We propose a blended approach which combines identification via heteroskedasticity with the widely used methods of sign … external instruments can prove necessary when the conditions for point identification through heteroskedasticity are not met … and offers a natural solution to the labeling problem inherent in purely statistical identification strategies. As a …

Contrary to claims in studies on financial economics, a sparse database often obscures the identification of parameters … in macroeconomic models. These identification problems originate from the poorly defined mapping between a structural … model and reduced-form parameters. Hence, researchers rely on prominent estimation methods, such as Bayesian approaches …
