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 be the Lie group given by the semidirect product of and

not the , are bounded from the Hardy space to . We also show

are not.Comment: This paper will be published in the "Annales de l'Institut Fourier
Heat maximal function on a Lie group of exponential growth
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
In the half-space , we consider the
Hermite-Schr\"odinger equation ,
with given boundary values on .
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
