Abstract A family of probability densities, which has proved useful in modelling the size distributions of various phenomens, including incomes and earnings, human settlement sizes, oil-field volumes and particle sizes, is introduced. The distribution, named herein as the double Pareto-lognormal or dPlN distribution, arises as that of the state of a geometric Brownian motion (GBM), with lognormally distributed initial state, after an exponentially distributed length of time (or equivalently as… 
The Normal-Laplace Distribution and Its Relatives
The normal-Laplace (NL) distribution results from convolving independent normally distributed and Laplace distributed components. It is the distribution of the stopped state of a Brownian motion with
To be consistent with Extreme Value Theory the pricing of excess-of-loss reinsurance contracts should be based on Pareto type distributions. In this context, two recent Pareto type distributions are
Geometrically stopped Markovian random growth processes and Pareto tails
Many empirical studies document power law behavior in size distributions of economic interest such as cities, firms, income, and wealth. One mechanism for generating such behavior combines
Tail behavior of geometrically stopped random growth processes and wealth distributions
Many empirical studies document power law behavior in size distributions of economic interest such as cities, firms, income, and wealth. One mechanism for generating such behavior combines iid
Log-growth distributions of US city sizes and non-Lévy processes
We study whether the hypothesis that the log-population of US cities follows a Levy process can be rejected or not. The result seems to be rejection. As a consequence, the cited process seems not
An Interpolating Family of Size Distributions
We introduce a new five-parameter family of size distributions on the semi-finite interval $[x_0, \infty), x_0 \geqslant 0$, with two attractive features. First, it interpolates between power laws,
From Pareto to Weibull – A Constructive Review of Distributions on ℝ +
Power laws and power laws with exponential cut-off are two distinct families of distributions on the positive real halfline. In the present paper, we propose a unified treatment of both families by
The accumulative law and its probability model: an extension of the Pareto distribution and the log-normal distribution
It is shown that the resulting accumulative distribution has properties that are akin to both the Pareto distribution and the log-normal distribution, which leads to a broad range of applications in modelling and fitting real data.
The power-law distribution in the geometrically growing system: Statistic of the COVID-19 pandemic
The power-law distribution is ubiquitous and its mechanism seems to be various. We find a general mechanism for the distribution. The distribution of a geometrically growing system can be


A New Model Of Income Distribution: The Pareto-Lognormal Distribution
To describe the distributions of personal income, many models have been suggested as alternatives to the Pareto distribution. This paper is not intended to review the whole literature about such a

The family of continuous type distributions such that the logarithm of the probability (density) function is a hyperbola (or, in several dimensions, a hyperboloid) is introduced and investigated. It

On the Rank-Size Distribution for Human Settlements
An explanation for the rank-size distribution for human settlements based on simple stochastic models of settlement formation and growth is presented. Not only does the analysis of the model explain
Dynamic Models for File Sizes and Double Pareto Distributions
The Recursive Forest File model, a new, dynamic generative user model that combines multiplicative models that generate lognormal distributions with recent work on random graph models for the web, explains the behavior of file size distributions, and may be useful for describing other power law phenomena in computer systems as well as other fields.

Application of Generalized Hyperbolic Lévy Motions to Finance
In standard mathematical finance, Brownian motion plays the dominating role as driving process for modelling price movements. In order to achieve a better fit to real-life data it is, however,
