[Endogenous and exogenous estrogens].
Presse medicale (Paris, France : 1983), 2019 Before menopause, women are protected from the risk of hypertension and atherosclerosis by endogenous estrogens. Estrogens have a vasoprotective role, while progesterone seems to have a neutral effect. Exogenous estrogens used in menopausal treatment have vascular effects.

Weak exogeneity in partially nonstationary models
This paper is dedicated to analysing the conditions for weak exogeneity in partially nonstationary models. After adopting a particular identification regime which is based on a triangularization of the parameters of the cointegration relations, we show ...

An Automatic Test of Super Exogeneity
We develop a new automatically-computable test for super exogeneity, using a variant of general-to-specific modeling. Based on the recent developments of impulse saturation applied to marginal models under the null that no impulses matter, we select the

Testing for Exogeneity in Nonlinear Threshold Models [PDF]
Most work in the area of nonlinear econometric modelling is based on a single equation and assumes exogeneity of the explanatory variables. Recently, work by Caner and Hansen (2003) and Psaradakis, Sola, and Spagnolo (2004) has considered the possibility

Testing a conditional form of exogeneity
We give two new approaches to testing conditional exogeneity. This condition ensures unconfoundedness and identification of structural effects. Our approaches permit the presence of treatment effects under the null, thereby complementing methods of ...
