This paper studies optimal non-linear income taxation in an empirically plausible model with labor supply responses at the intensive (hours, effort) and the extensive (participation) margin. In this model, redistributive taxation gives rise to a previously neglected trade-off between two aspects...

This paper calibrates the full social optimal inheritance tax rate derived by Piketty and Saez (2013) and shows that different assumptions on the form of the social welfare function lead to very different optimal inheritance tax rates, ranging from negative (under a utilitarian criterion) to...

Many OECD countries such as the USA, the UK or Switzerland are concerned with the affordability of utility services and the distributional consequences inherent in the pricing strategy of basic goods and services, such as electricity. However, the effectiveness of the electricity tariff as a...

Does significant market power or the presence of large rents affect optimal income taxation, calling for greater redistribution due to tainted gains? Or perhaps less because of an additional wedge that distorts labor effort? Do concerns about inequality have implications for antitrust,...

I study the optimal taxation of robots and labor income. In the model, robots substitute for routine labor and complement non-routine labor. I show that while it is optimal to distort robot adoption, robots may be either taxed or subsidized. The robot tax exploits general-equilibrium effects to...

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 optimal nonlinear income tax schedule when taxpayers earn multiple incomes and differ along many unobserved dimensions. We derive the necessary conditions for the government's optimum using both a tax perturbation and a mechanism design approach, and show that both methods produce...

This paper studies the aggregate and distributional implications of introducing consumption taxes into an otherwise deterministic version of the standard neoclassical growth model with income taxes only and heterogeneity across agents. In particular, the economic agents differ among each other...

This paper deals with tax policy responses to charitable giving, defined in terms of voluntary contributions to a public good, to which the government also contributes through public revenue; the set of tax instruments contains general, nonlinear taxes on income and charitable giving. In addition...

This paper examines optimal policy in a macroeconomic model with collateral constraints. Binding collateral constraints yield inefficient competitive equilibrium allocations because they distort the optimal utilization of real resources. I identify the set of policy instruments that can be used...
