    Convergence rates for density estimators of weakly dependent time series

    Full text link
    Assuming that (Xt)t∈Z(X_t)_{t\in\Z} is a vector valued time series with a common marginal distribution admitting a density ff, our aim is to provide a wide range of consistent estimators of ff. We consider different methods of estimation of the density as kernel, projection or wavelets ones. Various cases of weakly dependent series are investigated including the Doukhan & Louhichi (1999)'s η\eta-weak dependence condition, and the ϕ~\tilde \phi-dependence of Dedecker & Prieur (2005). We thus obtain results for Markov chains, dynamical systems, bilinear models, non causal Moving Average... From a moment inequality of Doukhan & Louhichi (1999), we provide convergence rates of the term of error for the estimation with the \L^q loss or almost surely, uniformly on compact subsets

    Optimality of the Child fiscal declaration by non-married couples

    Since 1995, fiscal law requires that un-married couples declare each of their children on only one of their two separate fiscal declarations. Thereby, their choice can be the result of an optimization, since the reduction each child implies depends on the family income. Fiscal simulation models generally assume that such an optimization takes place. It is interesting to see whether this assumption is supported by existing data. Such an examination can also contribute to forecasting what would be the impact of a full individualization of personal income tax, or contribute to the understanding of collective decision processes within households. Using the data from INSEEs 1997 Fiscal Revenue Survey, we provide an empirical study of this optimization, which leads to some stylized facts about household behavior. We observe that the fiscal optimum is reached by about three out of four un-married couples. This certainly does not result from a random choice. Indeed, the latter would lead to far more non-optimal couples. The losses that non-optimal couples incur are relatively weak. Three types of explanations can be given for this non-optimality : complex household structures (a former union or a large number of children), complex earning structures (non-wage earnings), or, mechanically, the level of earnings themselves.fiscal policy, household taxation, personal income tax

    Dependent Lindeberg central limit theorem and some applications

    Get PDF
    In this paper, a very useful lemma (in two versions) is proved: it simplifies notably the essential step to establish a Lindeberg central limit theorem for dependent processes. Then, applying this lemma to weakly dependent processes introduced in Doukhan and Louhichi (1999), a new central limit theorem is obtained for sample mean or kernel density estimator. Moreover, by using the subsampling, extensions under weaker assumptions of these central limit theorems are provided. All the usual causal or non causal time series: Gaussian, associated, linear, ARCH(∞\infty), bilinear, Volterra processes,......, enter this frame

    Un illustré sous l'Occupation : Le Téméraire

    No full text
    During the Occupation, the journals for children represented an ideological stake by no means insignificant. In the unoccupied Zone, the surroundings of Pétain encouraged the publication of newspapers most of them belonging to the catholic sphere of influence. In the occupied France, some journals survived until their publication stopped in spring 1942. In 1943, Le Téméraire, was given permission for publication. In spite of what as been written on the subject, it is not a german newspaper but a paper tolerated by the Germans and which was conceived by Jacques Bousquet, Abel Bonnard's private secretary. Le Téméraire was in a position until 1944 and thanks to the impression of 150 000 copies and a good presentation, the newspaper exercised a great influence over children. And yet, Le Téméraire propagated a militaristic ideology which was considered as authoritarian and sometimes racist. Then from reading clubs which looked neutral Jacques and his friends tried to set up an organisation for the youth.Pendant l'Occupation, les illustrés pour enfants ont constitué un enjeu non négligeable. En Zone libre, l'entourage de Pétain a encouragé la parution de journaux dont la majorité appartenait à la mouvance catholique. En Zone occupée, les illustrés cessent de paraître en 1942, mais en 1943 Le Téméraire obtient l'autorisation de paraître. Malgré ce qui a été écrit à ce sujet, ce n'est pas un journal allemand mais toléré par les Allemands, qui a été conçu par Jacques Bousquet, directeur de cabinet d'Abel Bonnard. En situation de monopole jusqu'à 1944, avec un tirage de 150 000 exemplaires et une bonne présentation, Le Téméraire exerça une influence certaine sur les enfants. Or il distillait une idéologie militariste, autoritaire et parfois raciste. Jacques Bousquet et ses amis ont aussi tenté de mettre sur pied une organisation de jeunesse à partir de clubs de lecteurs d'apparence anodine...Ragache Gilles.

    L’énigme de la croissance du PIB irlandais en 2015 : tentatives de réponse / Irish GDP Growth in 2015: A Puzzle and Propositions for a Solution

    In July 2016, the Irish statistical institute significantly revised GDP annual growth in 2015 from 7% to 26%. This revision does not correspond to a similar increase in employment nor in the accumulation of new physical capital, but to the relocation of preexisting intangible assets by multinationals to Ireland. This article provides a comprehensive depiction of the effects of these relocations on the Irish GDP and balance of payments in 2015. We question the need to change the accounting standards defining the macroeconomic aggregates and the framework for economic analysis. We conclude that an effort to adapt and revamp the standards of national accounts is thus necessary to achieve a consistent recording of multinationals’ transactions, crucially by clarifying the concept of economic ownership over production and intellectual property and then by facilitating its implementation.En juillet 2016, l’institut de statistique irlandais a revu fortement à la hausse la croissance annuelle du PIB pour l’année 2015, de 7% à 26%. Cette révision ne correspond pas à une hausse de l’emploi ni à une accumulation de capital physique, mais à la relocalisation d’actifs immatériels existants en Irlande par des multinationales. L’article présente de façon détaillée l’effet de ces relocalisations sur le PIB et la balance des paiements irlandais en 2015. Nous questionnons la nécessité de modifier les normes comptables qui définissent les agrégats macroéconomiques ou le cadre de l’analyse économique. Nous concluons à la nécessité d’un effort pour adapter et réviser les normes de la comptabilité nationale afin d’appréhender les transactions internationales des multinationales, particulièrement en clarifiant le concept de propriété économique de la production et des produits de la propriété intellectuelle, puis en facilitant sa mise en oeuvre.Khder Marie-Baïanne, Montornès Jérémi, Ragache Nicolas.
