We study the optimal observability of the tax base within the standard linear income tax problem, where observability is determined by the government’s investment into the accurate measurement of the tax base. We characterize the optimal level of observability and derive a new expression for...

Ausgehend vom bekannten Resultat von Atkinson und Stiglitz kommt man im Standardmodell der optimalen Besteuerung zum Schluss, dass eine Erbschaftssteuer ebenso wie andere indirekte Steuern keine Funktion hat, wenn eine optimale nichtlineare Einkommensteuer eingehoben wird. Beruecksichtigt man...

Given its significance in practice, piecewise linear taxation has received relatively little attention in the literature. This paper offers a simple and transparent analysis of its main characteristics. We fully characterize optimal tax parameters for the cases in which budget sets are convex...

The existing literature on optimal taxation typically assumes there exists a capacity to implement complex tax schemes, which is not necessarily the case for many developing countries. We examine the determinants of optimal redistributive policies in the context of a developing country that can...

Given its significance in practice, the piecewise linear tax system seems to have received disproportionately little attention in the literature on optimal income taxation. This paper offers a simple and transparent analysis of its main characteristics. -- Piecewise linear ; income ; taxation

Mirrlees' optimal income tax formula has never been proven rigorously, and it is hard to understand it in economic terms. We prove an analogous formula for an economy with finitely many persons. This is easy and allows a simple economic interpretation. Thereafter, Mirrlees' original formula is...
