In this work, two models for legal and illegal financiers are presented. The aim of the financiers are different: a bank try to minimize the defalt probabilityof the funded company, while the illegal financier aims to bring the company to bankruptcy and, at the same time, to obtain the maximum...

The aim of this article is to offer a simple framework for estimating the benefits and costs of anti-ML regulation, based on a prudent estimation of the economic value of worldwide money laundering. Using the multiplier model of the relationship between criminal markets revenues and money...

The aim of this paper is to propose a model of money laundering and an economic analysis model of money laundering by usury. The first one is an evolution of a model already present in the literature and the difference is in the way to evaluate the advantage for a criminal to reinvest the...

We develop a general theoretical model to compare two different policymakers both facing tax evasion. Policymakers differs in that they aim to maximize either the fiscal revenues (<InlineEquation ID="IEq1"> <EquationSource Format="TEX">$$T$$</EquationSource> </InlineEquation>) as in a social-democracy as, e.g., Sweden, or the GDP as in a capitalistic country as, e.g., the USA.

This paper discusses region wealth size distributions, through their member cities aggregated tax income. As an illustration, the official data of the Italian Ministry of Economics and Finance has been considered, for all Italian municipalities, over the period 2007-2011. Yearly data of the...

The yearly aggregated tax income data of all, more than 8000, Italian municipalities are analyzed for a period of five years, from 2007 to 2011, to search for conformity or not with Benford's law, a counter-intuitive phenomenon observed in large tabulated data where the occurrence of numbers...

After deriving a model describing the law of evolution of innovators and imitators the article focuses on their relationships under two different scenarios: prey-predator, in which innovators are regarded as preys, and competing species. Analytic results show that among the feasible equilibria...

Markov chain theory is proving to be a powerful approach to bootstrap highly nonlinear time series. In this work we provide a method to estimate the memory of a Markov chain (i.e. its order) and to identify its relevant states. In particular the choice of memory lags and the aggregation of...
