L'imposition optimale du revenu : une application au cas français

Abstract: [fre] Nous nous intéressons à l'imposition du revenu, entendue dans un sens très large puisque nous y incluons l'impôt négatif que constitue le versement de subventions accordées sous conditions de revenu. Dans le barème actuel, les taux marginaux d'imposition ont un profil en U. La progressivité de l'impôt se traduit par des taux élevés au sommet de la distribution des revenus. Mais le caractère d'allocation différentielle du RMI fait aussi apparaître des taux égaux à l'unité au bas de la distribution. Bien e… Show more

“…When labor supply, L, is observed, the simplest way to proceed would consist of assimilating productivity with observed hourly wage rates, and then using econometrically estimated values for the labor supply elasticity, ε, which, without loss of generality, might even be specified as a function of productivity, w (as it has been done in previous work on applied optimal income tax, see Diamond, 1998, Salanié, 1998, or d'Autume, 2001. This is the first approach pursued below.…”

“…For instance, under what condition would it be optimal for the marginal tax rate curve to be U-shaped [see Diamond (1998) and Saez (2001) for the US and Salanié (1998) for France]? Or could it be optimal to have 100 per cent effective marginal tax rates at the bottom of the distribution as implied by some minimum income programs [see Piketty (1997), d'Autume (2001, Choné and Laroque (2005) and Bourguignon and Spadaro (2000) in the case of France and other European countries]? Such questions were already addressed in the early optimal taxation literature and in particular in Mirrlees (1971) on the basis of arbitrary parametric representations of the distribution of individual abilities.…”

“…For a given elasticity of labour supply e, the underlying skill distribution has a Pareto index equal to a = 2:25 (1 + e) and a density f ( ) = K= 1+a . Regarding the elasticity of labour supply, we choose e = 0:2 as in d 'Autume (2000). Hence, a = 2:7:…”

“…Le critère maximin est quant à lui utilisé dans, par exemple, Atkinson [1975], Kanbur et Tuomala [1994], d'Autume [2001 et Boadway et Jacquet [2008]. 5 Nous adoptons ici l'hypothèse standard de la littérature appliquée qui s'intéresse à l'égalité des opportunités.…”
