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...

Our framework covers models of income taxation, public-goods provision or publicly provided private goods. Politicians are vote-share-maximizers. They can propose any policy that is...

How do taxes in the financial sector affect economic outcomes? We analyze a simple general equilibrium model with financial intermediation.

We study the interdependence of optimal tax and expenditure policies. An optimal policy requires that information on preferences is made available. We first study this problem from a general mechanism design perspective and show that efficiency is possible only if the individuals who decide on...
