A permutation code preserving a double Eulerian bistatistic
Visontai conjectured in 2013 that the joint distribution of ascent and
distinct nonzero value numbers on the set of subexcedant sequences is the same
as that of descent and inverse descent numbers on the set of permutations. This
conjecture has been proved by Aas in 2014, and the generating function of the
corresponding bistatistics is the double Eulerian polynomial. Among the
techniques used by Aas are the M\"obius inversion formula and isomorphism of
labeled rooted trees. In this paper we define a permutation code (that is, a
bijection between permutations and subexcedant sequences) and show the more
general result that two -tuples of set-valued statistics on the set of
permutations and on the set of subexcedant sequences, respectively, are
equidistributed. In particular, these results give a bijective proof of
Visontai's conjecture

Claims Reporting and Risk Bearing Moral Hazard in Workers' Compensation : The Canadian Context
This paper explores the Canadian context of workers' compensation (WC) by replicating, with Canadian data, a study carried out by Butler and Worrall (1991). These authors were the first to develop a simple model to separate claims reporting and risk bearing moral hazard in WC. Risk bearing moral hazard reflects the workers' incentive to carry more risk and consequently experience more accidents when benefits rise, while claims reporting moral hazard mirrors workers' incentive to file a claim. The estimation of these two moral hazard effects leads to results quite different with Canadian data than with American data.
Ce texte explore les mécanismes canadiens d'indemnisations pour accidents du travail en reproduisant avec des données canadiennes l'étude de Butler et Worrall (1991). Ces auteurs furent les premiers à développer un modèle simple pour distinguer deux types de risque moral liés à l'indemnisation des accidents du travail : Le risque lié au comportement préventif et le risque lié à la déclaration d'accidents. Le premier est associé à la tendance des travailleurs de prendre plus de risque lorsque la générosité des indemnisations augmente, alors que le second est associé à leur propension à faire une réclamation lorsqu'ils ont un accident. L'estimation de ces deux types de risque moral, avec des données canadiennes, donne des résultats trés différents de ceux présentés par Butler et Worrall.Worplace Accidents, Workers'Compensation, Moral Hazard, Accidents du travail, indemnisations, risque moral
