Die Konsolidierung der Staatsfinanzen nach der gegenwärtigen Finanz- und Wirtschaftskrise wird eines der zentralen wirtschaftspolitischen Themen der nächsten Jahre sein: Die Regelungen zur "Schuldenbremse" sehen für den Bundeshaushalt bis 2016 einen annähernd ausgeglichenen Haushalt vor, und...

Gegenstand dieses Beitrags ist eine quantitativ orientierte Diskussion einiger Wirkungen einer Umstrukturierung des Steuersystems anhand der neuesten und wesentlich erweiterten Version des Konstanzer aggregierten Ungleichgewichtsmodells für die westdeutsche Volkswirtschaft für den Zeitraum von...

A common assumption in the optimal taxation literature is that the social planner maximizes a welfarist social welfare function with weights decreasing with income. However, high transfer withdrawal rates in many countries imply very low weights for the working poor in practice. We reconcile...

This paper examines the implications of habit formation in private and public consumption for the Pareto-efficient provision of public goods, based on a two-period model with nonlinear taxation. If the public good supply is time-invariant, the presence of habit formation generally alters the...

How much information should governments reveal to consumers if consumption choices have uninternalized consequences to society? How does an alternative tax policy compare to information disclosure? We develop a price theoretic model of information design that allows empiricists to identify the...

We study the optimal design of student financial aid as a function of parental income. We derive optimal financial aid formulas in a general model. For a simple model version, we derive mild conditions on primitives under which poorer students receive more aid even without distributional...

Are reforms towards individual taxation politically feasible? Are they desirable from a welfare perspective? We develop a method to answer such questions and apply it to the US federal income tax since the 1960s. Main findings are: As of today, Pareto-improvements require a move away from joint...
