We derive expressions for the first-order bias of the MLE for a Poisson regression model and show how these can be used to adjust the estimator and reduce bias without increasing MSE. The analytic results are supported by Monte Carlo simulations and three illustrative empirical applications.

The firm size distribution is considered as Pareto distribution. In the present paper, we show that the Pareto distribution of firm size results from the spillover network model which was introduced in Konno (2010).

A simple model of the distribution of wealth is presented. In such a model the distribution of wealth follows a Pareto type II distribution whose parameters depend on the growth rates discussed in the book. Compared to previous studies of the asymptotic distribution of wealth in economies...
