Le Paradoxe de la redistribution de Walter Korpi et Joakim Palme (1998) postule que les États-providences qui ont des dépenses sociales moins ciblées redistribuent davantage. Ive Marx, Lina Salanauskaite et Gerlinde Verbist (2013) ont toutefois constaté que le paradoxe démontré grâce à une corrélation entre un indice de redistribution et un indice de ciblage des dépenses sociales n'était plus valide dans les années 2000. En reproduisant les corrélations, il apparaît que l'augmentation importante du ciblage dans des pays qui redistribuent beaucoup comme le Danemark et la Suède est la principale cause de la disparition de la corrélation entre redistribution et ciblage. Lors des crises économiques dans les années 1980 et 1990, les prestations maximales déjà relativement faibles ainsi que la volonté de maintenir les prestations minimums et les taux de remplacement de la part des partis sociaux-démocrates ont poussé les gouvernements danois et suédois à réduire les prestations maximales afin de limiter l’augmentation des dépenses, augmentant ainsi le ciblage des dépenses sociales tout en préservant le caractère universel des programmes. L’augmentation du ciblage des dépenses sociales n’a pas eu d’effets négatifs sur la redistribution particulièrement au Danemark où la redistribution a augmenté et les inégalités diminué entre la fin des années 80 et le milieu des années 2000.

We consider the following question: does market failure justify redistribution? We argue that the general answer to this question is no, in the sense that policies for correcting market failures do not aim at producing a "desirable" income distribution. This follows from the fact that, by construction, market failure is a deviation from "efficiency" that does not involve any notion of a desirable distribution of welfare (or income). However, there are special cases where a "corrective measure" involving redistribution can offset a market failure, so this can provide a form of efficiency- based justification for redistribution.

We compute the optimal non-linear tax policy for a dynastic economy with uninsurable risk, where generations are linked by dynastic wealth accumulation and correlated incomes. Unlike earlier studies, we find that the optimal long-run tax policy is moderately regressive. Regressive taxes lead to higher output and consumption, at the expense of larger after-tax income inequality. Nevertheless, equilibrium effects and the availability of self-insurance via bequests mitigate the impact of regressive taxes on consumption inequality, resulting in improved average welfare overall. We also consider the optimal once-and-for-all change in the tax system, taking into account the transition dynamics. Starting at the U.S. status quo, the optimal tax reform is slightly more progressive than the current system.

Ernst Zermelo presented an argument showing that there is no set of all sets that are members of themselves in a letter to Edmund Husserl on April 16th of 1902, and so just barely anticipated the same contradiction in Betrand Russell’s letter to Frege from June 16th of that year. This paper traces the origins of Zermelo’s paradox in Husserl’s criticisms of a peculiar argument in Ernst Schroeder’s 1890 Algebra der Logik. Frege had also criticized that argument in his 1985 “A Critical Elucidation of Some Points in E. Schroeder Vorlesungen über die Algebra der Logik”, but did not see the paradox that Zermelo found. Alonzo Church, in “Schroeder’s Anticipation of the Simple Theory of Types” from 1939, cricized Frege’s treatment of Schroeder’s views, but did not identify the connection with Russell’s paradox.
