We describe recent progress in several areas related to endogeneity, including: choice set formation and attention to attributes; interactions among decision-makers; respondents’ strategic behavior in answering stated preference choices; models of multiple discrete/continuous choice; distributions of willingness-to-pay; and methods for handling traditionally endogenous explanatory variables. 1 ...
Modern, high dimensional data has renewed investigation on instrumental variables (IV) analysis, primary focusing on estimation of the included endogenous variable under sparsity and little attention towards specification tests. This paper studies in high dimensions the Durbin-Wu-Hausman (DWH) test, a popular specification test for endogeneity in IV regression. We show, surprisingly, that the D...
Keyword: Quantile regression, endogeneity test, Hausman test. Mots clé de la conférence: Econométrie, Modèles semi et non paramétriques Abstract: In this paper we develop a test to detect the presence of endogeneity in di¤erent quantiles in the conditional distribution of a variable of interest. This Hausman test type is based on one estimator consistent only under no endogeneity at the examine...
Dynamic endogeneity occurs when the current values of a study’s independent variables are affected by past dependent variables, which can lead to biased estimates. Our analysis 80 empirical papers published in Journal International Business Studies uncovers cases inappropriate treatment dynamic endogeneity. simulations reveal factors that bias fixed effects estimator and highlight advantages di...
Researchers treated seed technology and crop yield as exogenous, thereby generating bias estimates. In practice, increases it’s stimulated by social capital other factors. This paper develops a choice model of maize-seed exogenously, then tested corrected for causality. A multistage sampling procedure was adopted using seven Agricultural Development Programme zones drawn from purposively select...
Abstract Background: Molecular imprinting is a method for synthesizing polymers with structure-selective adsorption properties with applications such as, selectivity binding, drug delivery systems and anti-bodies. The present study aims at optimizing the preparation of molecularly imprinted polymer (MIP) against l-phenylalanine, in order to increase phenylalanine-binding in Enzymatic Intestinal...
Sediment selectivity during transport may provide basic information for evaluating on-site and off-site impacts of the soil erosion. Limited information is, however, available on the selectivity of sediments in rill erosion, particularly in the rainfed furrows. Toward this, the sediment selectivity was investigated in three soil textures (loam, loamy sand sand clay loam) under 10% slope using 9...
We propose a new methodology for estimating the demand and cost functions of differentiated products models when demand and cost data are available. The method deals with the endogeneity of prices to demand shocks and the endogeneity of outputs to cost shocks, but does not require instruments for identification. We establish non-parametric identification, consistency and asymptotic normality of...
