Dagenais (1999) and Lucchetti (2002) have demonstrated that the naive GMM estimator of Grogger (1990) for the probit model with an endogenous regressor is not consistent. This paper completes their discussion by explaining the reason for the inconsistency and presenting a natural solution....

The inference in probit models relies on the assumption of normality. However, tests of this assumption are not implemented in standard econometric software. Therefore, the paper presents a simple representation of the Bera-Jarque-Lee test, that does not require any matrix algebra. Furthermore,...

Weak identification is a well known topic for linear multiple equation models. However, little is known whether this problem also matters for probit models with endogenous covariates. Therefore, the behaviour of the usual z-statistic in case of weak identification is analysed in a simulation...

Zusammenfassung Bisherige Studien für Gesamtdeutschland haben ermittelt, dass mehr als die Hälfte der Haushalte, die zum Bezug von Sozialhilfe berechtigt sind, diesen Anspruch nicht geltend machen. Dies widerspricht der Intuition. Das Ziel unserer Studie ist deshalb zum einen, mit Hilfe des...
