On valid descriptive inference from non-probability sample
Statistical Theory and Related Fields, 2019 We examine the conditions under which descriptive inference can be based directly on the observed distribution in a non-probability sample, under both the super-population and quasi-randomisation modelling approaches.

Confronting Model Misspecification in Macroeconomics [PDF]
We estimate a Markov-switching mixture of two familiar macroeconomic models: a richly parameterized DSGE model and a corresponding BVAR model. We show that the Markov-switching mixture model dominates both individual models and improves the fit ...

Uncertainty quantification for misspecified machine learned interatomic potentials
npj Computational MaterialsThe use of high-dimensional regression techniques from machine learning has significantly improved the quantitative accuracy of interatomic potentials. Atomic simulations can now plausibly target quantitative predictions in a variety of settings, which ...

Acknowledgement Misspecification in Macroeconomic Theory [PDF]
We explore methods for confronting model misspecification in macroeconomics. We construct dynamic equilibria in which private agents and policy makers recognize that models are approximations.

International Journal of Finance &Economics, EarlyView.ABSTRACT This study investigates how ESG rating divergences and climate transition risks jointly influence portfolio performance. Using a newly constructed composite Environmental (E) score derived from principal component analysis (PCA) across three leading ESG providers (Eikon, RobecoSAM, Sustainalytics), we build industry‐adjusted portfolios for 389
