Asymptotic and finite-sample properties of estimators based on stochastic gradients Panos Toulis and Edoardo M. Airoldi University of Chicago and Harvard University Panagiotis (Panos) Toulis is an Assistant Professor of Econometrics and Statistics at University of Chicago, Booth School of Business (panos.toulis@chicagobooth.edu). A sequence of estimates is said to be consistent, if it converges in probability to the true value of the parameter being estimated: ^ → . The article investigates the finite sample properties of estimators for spatial autoregressive models where the disturbance terms may follow a spatial autoregressive process. Furthermore, we consider broad classes of estimators such as the k-class estimators and evaluate their promises and limitations as methods to correctly provide finite sample inference on the structural parameters in simultaneous equations. The estimator ^ is normally distributed, with mean and variance as given before: ^ ∼ (, −) where Q is the cofactor matrix. We consider broad classes of estimators such as the k-class estimators and evaluate their promises and limitations as methods to correctly provide finite sample inference on the structural parameters in simultaneous equa-tions. have higher variance than other matching estimators, and Hirano, Imbens, and Ridder (2003) show that reweight- First of all, under the strict exogeneity assumption the OLS estimators ^ and ... (0, σ 2 I n)), then additional properties of the OLS estimators can be stated. Introduction. The finite sample properties of the estimators are investigated by means of Monte-Carlo simulations depending of the sample size, the weights matrix, the presence of cross-equation correlation and the nature of the instruments. perspective of the exact finite sample properties of these estimators.

Finite-Sample Properties of the 2SLS Estimator During a recent conversation with Bob Reed (U. Canterbury) I recalled an interesting experience that I had at the American Statistical Association Meeting in Houston, in 1980. In most cases, however, exact results for the sampling distributions of estimators with a finite sample are unavailable; examples include maximum likelihood estimators and most nonparametric estimators. An empirical example illustrating the different estimators is proposed. Unbiasedness, relative efficiency and MSE-criterion Unbiasedness.

Propensity Score Reweighting and Matching Estimators Matias Busso IDB, IZA John DiNardo Michigan, NBER Justin McCrary Berkeley, NBER March 20, 2013 Abstract Fro lich (2004) compares the finite sample properties of reweighting and matching estimators of average treatment effects and concludes that reweighting performs far worse than even the simplest matching estimator. In particular we investigate the finite sample behavior of the feasible generalized spatial two‐stage least squares (FGS2SLS) estimator introduced by Kelejian and Prucha (1998), the maximum likelihood (ML) … Kocherlakota (1990b). 70, University of New England, Armidale. On Finite Sample Properties of Alternative Estimators of Coefficients in a Structural Equation with Many Instruments ∗ T. W. Anderson † Naoto Kunitomo ‡ and Yukitoshi Matsushita § July 16, 2008 Abstract We compare four different estimation methods for the coefficients of a linear structural equation with instrumental variables. However, their statistical properties are not well understood, in theory. However, all of these relate to the case of non-stochastic covariates, and it is this last assumption that we relax in this paper. The Finite Sample Properties of Sparse M-estimators with Pseudo-Observations Benjamin Poignard, Jean-David Fermaniany September 25, 2019 Abstract We provide nite sample properties of general regularized statistical criteria in the presence of pseudo-observations. A number of results relating to the finite-sample properties of the MLE (and some other estimators) for the logit model have also been established. New Evidence on the Finite Sample Properties of Propensity Score Matching and Reweighting Estimators Matias Busso IDB, IZA John DiNardo Michigan, NBER Justin McCrary Berkeley, NBER January 30, 2009 Abstract Currently available asymptotic results in the literature suggest that matching estimators have higher variance than reweighting estimators. Maximum-likelihood estimators have no optimum properties for finite samples, in the sense that (when evaluated on finite samples) other estimators may have greater concentration around the true parameter-value.
