We consider a model with a population consisting of earners and retired persons; elderly care is publicly provided. There is one big city, where congestion effects and agglomeration forces are at work, and a number of small villages. We show how the externalities related to population mobility...

In most countries, average income varies with age. In this paper we investigate if and how it is possible to enhance the redistributive mechanism by relating tax payments to age. Using an OLG model where some individuals are low skilled all their life while others are low skilled when young but...

This paper concerns optimal nonlinear labor income taxation in an economy with union wage setting and endogenous hours of work. The purpose is to study the determinants of tax progression. We show that the optimal degree of progression of the labor income tax depends on the extent to which the...

The theory of forest management is applied by estimating a model of timber supply under nonlinear income taxation. Timber supply is derived from a two-period optimization problem, which provides a simple framework for dealing with intertemporal decisions. A contribution of the paper is to allow...
