“…Local misspecification has been used in a number of papers, which include, among others, Newey (1985), Berkowitz, Caner, and Fang (2012), Conley, Hansen, and Rossi (2012), Guggenberger (2012), and Bugni and Ura (2019), and has antecedents in the literature on robust statistics (see Huber and Ronchetti (2009), and references therein). Andrews, Gentzkow, and Shapiro (2017) considered this setting and note that asymptotic bias of a regular estimator can be calculated using influence function weights, which they call the sensitivity, and show how such calculations can be used for sensitivity analysis in applications (see also extensions of these ideas in Andrews, Gentzkow, and Shapiro 2020 and Mukhin 2018).…”
