We theoretically express the Laffer tax rate on capital income as a function of the elasticities of capital income (the "direct" elasticity) and of labor income (the "cross" elasticity) with respect to the net-of-tax rate on capital income. We estimate these elasticities using salient capital...

We consider the problem of repeatedly choosing policies to maximize social welfare. Welfare is a weighted sum of private utility and public revenue. Earlier outcomes inform later policies. Utility is not observed, but indirectly inferred. Response functions are learned through experimentation....

Imperfect altruism between generations may lead to insufficient capital accumulation. We study the welfare consequences of taxing the rent on a fixed production factor, such as land, in this setting. We prove that taxing the rent is welfare-enhancing as it increases capital investment. This...

We analyze optimal taxation of labor and capital income in a life-cycle framework with idiosyncratic income risk. We provide a novel decomposition of labor income tax formulas into a redistribution and an insurance component. The latter is independent of the social welfare function and...

The total social benefits of college education exceed the private benefits because the government receives a share of the monetary returns in the form of income taxes. We study the policy implications of this fiscal externality in an optimal dynamic tax framework. Using a variational approach we...

We consider a two small open economies model with cross-border pollution that is generated from consumption. Within this framework we examine i) the non-cooperative equilibrium consumption taxes and compare them to when pollution is only local, ii) the cooperative equilibrium consumption taxes...

The European Commission is evaluating the performance of the common VAT, which has many shortcomings. The numerous exemptions and differentiated rate structures violate the logic and functionality of the VAT. The exemptions distort input choices and outsourcing policies. Reduced rates are...

We consider a government facing a constraint on the total consumption of a specific good with varieties, and formulate an optimal commodity tax problem under a consumption target. We obtain a uniform pricing result (similar to the familiar uniform taxation rule): setting the same consumer price...

We combine consumption generated cross-border pollution and public pollution abatement in a theoretical framework to examine the efficiency of the destination and origin principles of commodity taxation. The key result of our study is that with public pollution abatement, the non-cooperative...

To help first- or second-year graduate students in economics apply their theoretical training, this paper shows how to solve a simple and intuitive computable general equilibrium (CGE) model using a calculator. Because this simplified Harberger model uses Cobb Douglas functional forms for...
