We analyze the taxation of top personal incomes in Germany on the basis of an integrated data file of individual tax returns and a general household survey for the years 1992 2002. The unique feature of this integrated data set is that it includes all taxpayers in the top percentile of the gross income distribution. We show that despite substantial tax base erosion and significant reductions of...

We analyze the taxation of top personal incomes in Germany on the basis of an integrated data file of individual tax returns and a general household survey for the years 1992 – 2002 which includes all taxpayers in the top percentile of the gross income distribution. We show that the distribution of the tax burden is highly concentrated, and that German income taxation has remained effectively p...

"A common hypothesis regarding the distribution of income is that it tends to become more unequal in the initial and middle stages of economic development, in part because of demographic changes. However, previous studies of the effect of demographic changes on income distribution are not based on the underlying micro determinants of the income components." In the present paper, "the micro de...

PURPOSE We explored predictors of nutritional status change from 11 to 15 years of age by analyzing prospective data. METHODS We collected data at 11 and 15 years of age from individuals born in 1993 in Pelotas, Brazil. We assessed nutritional status using body mass index (BMI) for age in z-score according to the World Health Organization 2007 standards. Independent variables collected at 11 ...

In this paper we consider new upscaling and homogenization methods for the pressure equation that are less sensitive to the boundary condition assumptions than many other published methods. We start from the discretized pressure equation and rely on the construction of subproblems with signii-cantly fewer unknowns, describing the behaviour of the solution of the ne-grid problem in suitable subs...

The issue addressed in this paper is the optimal taxation of incomes earned tn the home economy, and of incomes earned abroad, when people can migrate. As a preliminary, the optimal taxation of home incomes when there is migration and no taxation of foreign incomes, is discussed. Then in a more general setting, we deal with optimal taxation of different kinds of labour when another kind of labo...
