Recently a blind source separation model was suggested for spatial data together with an estimator based on the simultaneous diagonalization of two scatter matrices. The asymptotic properties of this estimator are derived here and a new estimator, based on the joint diagonalization of more than two...

In this paper, we use a differentiated-products setup to assess the impact on competition of a merger between Greif and Rheem South Africa. Both parties are active in the industrial packaging products sector. The parties’ activities overlap, among others, in the production of large steel drums. Our...
