Empirical Evidence Concerning the Finite Sample Performance of EL-Type Structural Equation Estimation and Inference Methods AgEcon
Mittelhammer, Ronald C.; Judge, George G.; Schoenberg, Ron.
This paper presents empirical evidence concerning the finite sample performance of conventional and generalized empirical likelihood-type estimators that utilize instruments in the context of linear structural models characterized by endogenous explanatory variables. There are suggestions in the literature that traditional and non-traditional asymptotically efficient estimators based on moment equations may, for the relatively small sample sizes usually encountered in econometric practice, have relatively large biases and/or variances and provide an inadequate basis for estimation and inference. Given this uncertainty we use a range of data sampling processes and Monte Carlo sampling procedures to accumulate finite sample empirical evidence concerning...

Hedonic Housing Prices and Agricultural Pollution: An Empirical Investigation on Semiparametric Models AgEcon
Bontemps, Christophe; Simioni, Michel; Surry, Yves R..
The objective of this paper is to assess the impact on property values of agricultural pollution using alternative semiparametric hedonic price models. The proposed model specifications are made up of two parts: a partially linear component for house characteristics and a non (semi) parametric form to represent the non linear influence of agricultural pollution. A general-to-specific search procedure is adopted to select the best model specification. An application of theses parametric models to rural townships indicates that pollution resulting on livestock operations have a significant nonlinear impact on house prices.
