We develop and estimate a model of jointly optimal income taxes for different types of income. Compared to standard optimal tax formulas, optimal schedular income tax rates additionally depend on cross-elasticities between tax bases capturing fiscal externalities. We discuss two applications:...

Several recent studies show that the elasticity of taxable income (ETI) is not a sufficient statistic for the welfare costs of taxation due to factors such as taxbase shifting. This paper provides an additional argument demonstrating the non-sufficiency of the ETI, namely tax deductions....

The elasticity of taxable income (ETI) is often interpreted as a sufficient statistic to assess the welfare costs of taxation. Building on the conceptual framework of Chetty (2009), we show that this assertion does no longer hold for tax systems with deduction possibilities if (i) deductions...

Das vorliegende Gutachten untersucht die Auswirkungen einer Neuordnung des deutschen Ertragsteuersystems nach dem Vorschlag von Joachim Mitschke (2004) auf Steueraufkommen, Beschäftigung und Wirtschaftswachstum. Grundlage der Analyse ist das Steuer-Transfer-Simulationsmodell FiFoSiM des...

In dieser Studie werden die Verteilungseffekte der Steuerpolitik in der 19. Legislaturperiode untersucht. Im ifo Mikrosimulationsmodell ifo-MSM-TTL werden Be- und Entlastungen verschiedener Haushaltstypen und Einkommensgruppen sowie die Veränderung der Ungleichheits- und Armutsmaße durch...
