Analysis of industrial dynamics: A note on the relationship between firmsʹ size and growth rate

In this paper it is shown that, under the Marshall and Olkin [Marshall, A.W., Olkin, I., 1967. A Multivariate Exponential Distribution. American Statistical Association Journal, pp. 30–44.] conditions, it is possible to prove the appearing of two stylized facts in industrial dynamics: Pareto shape (firmsʹ size) and Laplace distribution (firmsʹ growth rates).
