    Redistribution, Occupational Choice and Intergenerational Mobility: Does Wage Equality Nail the Cobbler to His Last?

    The classical Roy-model of selection on the labor market is extended in order to analyze intergenerational mobility. This is done by linking ability uncertainty to family background. I derive implications for the allocation of talent and for background dependent earnings patterns within occupations and show that a very compressed wage structure can cause negative sorting of people with family background in the occupation with low returns to ability. I also study the effects of income redistribution on mobility and talent allocation. It is found that a redistributive welfare system either reduces vertical mobility or enhances it at the cost of a shrinking proportion of people choosing the occupation with high returns.Intergenerational mobility; Occupational choice; Allocation of talent; redistribution

    Boundedness from H^1 to L^1 of Riesz transforms on a Lie group of exponential growth

    Let GG be the Lie group given by the semidirect product of R2R^2 and R+R^+ endowed with the Riemannian symmetric space structure. Let X0,X1,X2X_0, X_1, X_2 be a distinguished basis of left-invariant vector fields of the Lie algebra of GG and define the Laplacian Δ=(X02+X12+X22)\Delta=-(X_0^2+X_1^2+X_2^2). In this paper we consider the first order Riesz transforms Ri=XiΔ1/2R_i=X_i\Delta^{-1/2} and Si=Δ1/2XiS_i=\Delta^{-1/2}X_i, for i=0,1,2i=0,1,2. We prove that the operators RiR_i, but not the SiS_i, are bounded from the Hardy space H1H^1 to L1L^1. We also show that the second order Riesz transforms Tij=XiΔ1XjT_{ij}=X_i\Delta^{-1}X_j are bounded from H1H^1 to L1L^1, while the Riesz transforms Sij=Δ1XiXjS_{ij}=\Delta^{-1}X_iX_j and Rij=XiXjΔ1R_{ij}=X_iX_j\Delta^{-1} are not.Comment: This paper will be published in the "Annales de l'Institut Fourier

    Let G be the Lie group R^2\rtimes R^+ endowed with the Riemannian symmetric space structure. Let X_0, X_1, X_2 be a distinguished basis of left-invariant vector fields of the Lie algebra of G and define the Laplacian \Delta=-(X_0^2+X_1^2+X_2^2). In this paper, we show that the maximal function associated with the heat kernel of the Laplacian \Delta is bounded from the Hardy space H^1 to L^1. We also prove that the heat maximal function does not provide a maximal characterization of the Hardy space H^1.Comment: 18 page

    Tournaments and Unfair Treatment

    This paper introduces the negative feelings associated with the perception of being unfairly treated into a tournament model and examines the impact of these perceptions on workers’ efforts and their willingness to work overtime. The effect of unfair treatment on workers’ behavior is ambiguous in the model in that two countervailing effects arise: a negative impulsive effect and a positive strategic effect. The impulsive effect implies that workers react to the perception of being unfairly treated by reducing their level of effort. The strategic effect implies that workers raise this level in order to improve their career opportunities and thereby avoid feeling even more unfairly treated in the future. An empirical test of the model using survey data from a Swedish municipal utility shows that the overall effect is negative. This suggests that employers should consider the negative impulsive effect of unfair treatment on effort and overtime in designing contracts and determining on promotions.Unfair treatment; tournaments

    On the boundary convergence of solutions to the Hermite-Schr\"odinger equation

    Full text link
    In the half-space Rd×R+\mathbb{R}^d \times \mathbb{R}_+, we consider the Hermite-Schr\"odinger equation iu/t=Δu+x2ui\partial u/\partial t = - \Delta u + |x|^2 u, with given boundary values on Rd\mathbb{R}^d. We prove a formula that links the solution of this problem to that of the classical Schr\"odinger equation. It shows that mixed norm estimates for the Hermite-Schr\"odinger equation can be obtained immediately from those known in the classical case. In one space dimension, we deduce sharp pointwise convergence results at the boundary, by means of this link.Comment: 12 page
