ABSTRACT:  In this paper, we propose a statistical model to characterize the null hypothesis of the random product size for multi-product exporters. It serves as a benchmark to test the empirical facts and model predictions about multi-product exporters. Our contribution is to show that a number of stylized facts characterizing multi-product exporters and used to motivate such theories as core-competencies, productivity being a driver of both scope and scale, and economies of scope among others, are spurious. The benchmark model provides alternative moments to test the validity of these theories.
