Un Test de la Stabilite Structurelle des Parametres Estimee Par la Methode des Moments Generalisee (Mmg) Est Presente. le Test Est Predictif, Base Sur L'examen de Previsions Sur un Sous-Echantillon le Test S'applique Sur une Grande Variete de Modeles D'inference Dynamiques, Modeles D'equations...

In This Paper We Present and Implement an Econometric Test of Both Negative Semi-Definiteness of the Matrix of Compensated Price Effects and of the Negative Quasi-Definiteness of the Matrix of Uncompensated Price Effects. This Test Allows Us to Evaluate Two Alternative Characterizations of...

Seasonal Effects in Qualitative Responses of Monthly Business Surveys, Modeled with Log-Linear Probability Methods, Can Be Extracted Like in Linear Regression Or Some Time Series Models by Using Dummy Variables. There Is Another Route to Extract the Seasonal Effect, Which Is to Unique to...

We Present Several Small-Sample Results on the Distribution of Residuals and Estimators of the Disturbance Variance in Econometric Models. We Consider General Linear and Nonlinear Models with Stochastic Regressors and Possibly Nonlinear Restrictions on the Parameters. These Include...

This Paper Gives Non-Uniform Bounds on the Tail Areas of the Permutation Distribution of the Usual Student's T Statistic When the Observations Are Independent with Symmetric Distributions. As Opposed to Uniform Bounds, Non-Uniform Bounds Depend on the Observed Sample. It Is Shown That the...

This Paper Shows That Rindskopf's Parameterization Technique Is Not an Acceptable Solution to the Heywood Problem, Especially, If One Is Interested in Standard Errors and T-Statistics for the Parameter Estimates of a Linear Structural Model. Simple Alternative Solutions Are Proposed and...
