The recognition that contracts have a time dimension has given rise to a very abundant literature since the end of the 1980s. In such a dynamic context, the contract may take place over several periods and develop repeated interactions. Then, the principal topics of the analysis are commitment,...

In the presence of heteroskedasticity of unknown form, the Ordinary Least Squares parameter estimator becomes inefficient and its covariance matrix estimator inconsistent. Eicker (1963) and White (1980) were the first to propose a robust consistent covariance matrix estimator, that permits...

We consider a class of linear regression model with extreme distribution noise. We show by a mean of point process technique that the asymptotic distribution of the maximum is the same as the one of the max of the noise process, under specific conditions.
