Fleming-Viot processes : two explicit examples

The purpose of this paper is to extend the investigation of the Fleming-Viot process in discrete space started in a previous work to two specific examples. The first one corresponds to a random walk on the complete graph. Due to its geometry, we establish several explicit and optimal formulas for the Fleming-Viot process (invariant distribution, correlations, spectral gap). The second example corresponds to a Markov chain in a two state space. In this case, the study of the Fleming-Viot particle system is reduced to the study of birth and death process with quadratic rates.Comment: 17 pages, 1 figure. arXiv admin note: substantial text overlap with arXiv:1312.244

Risk Management for Targeting Customs Controls in Developing Countries: A Risky Venture for Revenue Performance?

Customs authorities in developing countries are often reluctant to forgo systematic inspections for fear of risking revenue loss. Such physical inspections, however, impede rather than facilitate trade. Control selectivity is therefore a key issue in customs administration reform. This paper shows how a sophisticated risk management method can facilitate trade by automatically and rationally selecting transactions, with the end result of actually enhancing revenue performance.trade facilitation, fiscal revenues, risk management, moral hazard, customs controls

Résurgence du mouvement antiprohibitionniste

Recently, one could witness a resurgence of the debate on the drug policy, a debate that many thought passé since the late seventies. Adding to the already existing arguments against the international conventions and the national drug laws the negative experience of 15 years of repression and the fait accompli of the lost «war against drugs», the new movement, an international one, has become openly anti-prohibitionist
