In 2002 we published a paper in which we used state space time series methods to analyse the teenage employment-federal minimum wage relationship in the US (Bazen and Marimoutou, 2002). The study used quarterly data for the 46 year period running from 1954 to 1999. We detected a small, negative...

The marketing literature often argues that the random coefficient logit model gives more realistic results than the homogeneous logit. The purpose of this paper is to show that the random coefficients logit improves upon, but does not completely solve the problems of the homogeneous logit. We...

We explore practical methods of carrying out Lagrange Multiplier tests for variance components in two models in which the derivatives needed for the test are identically zero at the restricted estimates, the random effects probit model and the stochastic frontier model. The techniques are...
