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...

The German tax system allows tax deductibility of costs of studying either as special expenses or as work-related tax deductions. However, filing tax returns and utilizing tax deductibility of costs of studying are hampered if benefits are not obvious, if costs are not automatically accounted...

A recent wave of literature, partly motivated by presidential campaign tax reform plans, analyzes tax expenditure limitation proposals. These reforms are often advanced not only, or even primarily, because they reduce distortions caused by favoritism for some types of expenditures over others....
