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...

We analyze the compliance costs of individual taxpyers resulting from the German income tax. using survey data that has been raised between December 2008 and April 2009, we find evidence for a considerably higher cost burden of self-employed taxpaxers. Taxable income and the demand for external...

What are the implications of (endogenous) directed technical change for the design of redistributive income taxes? I study this question in a Mirrleesian economy augmented to include endogenous technology development and adoption choices by firms. Under certain conditions, any progressive tax...

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...

We analyse attempts to implement personalised regulation in the form of sin licenses (O'Donoghue and Rabin 2003, 2005, 2007) to correct the distortion in the consumption of a harmful good when consumers suffer from varying degrees of self-control problems. We take into account the possibility...

We analyze personalized regulation in the form of sin licenses to correct the distortion in the consumption of a harmful good when consumers suffer from varying degrees of self-control problems. We take into account preference uncertainty, which generates a trade-off between flexibility and...

We study the effects of different tax reporting mechanisms in experi-mental double auction markets in the laboratory. The sales tax is paidby the seller, and we compare market outcomes in a no-tax conditionto cases where (i) tax evasion is impossible, (ii) taxes can be evaded butthere is an...

In this paper we present a life-cycle model with human capital investment during working life through training and provide a novel empirical test of human capital theory. Using a sizable pension reform which shifts the retirement age between two adjacent cohorts by three years, we document...
