Until 2009, the United Kingdom operated a system of worldwide taxation. Taxation of foreign income was deferred until repatriated as dividends, leaving UK-owned multinational firms the possibility of avoiding UK taxation by delaying dividend payments and keeping earnings abroad. In 2009, the UK...

In this paper we estimate labor force participation responses for married women in Sweden using population-wide register data and detailed information about individuals' budget sets. For identification we exploit a reform in the system for housing allowances in 1997 which affected participation...

We analyze Pareto-efficient tax breaks for work-related expenses in a Mirrleesian environment. Individuals are heterogenous in their ability. In addition to a labor-leisure choice, they decide how to spend their money between normal consumption and work-related goods. We derive an efficiency...

We analyze Pareto-efficient tax deduction rules for work-related expenses. Pareto efficiency dictates a strict rule for marginal deductions along the income distribution. An immediate implication is a recipe for designing Pareto-improving reforms. We apply our theory and simulate a...

This paper provides necessary and sufficient conditions for the existence of Pareto-improving tax reforms. The conditions can be expressed as sufficient statistics and have a wide range of potential applications in public finance. We discuss one such application in detail: the introduction of...

We analyze Pareto-efficient tax deduction rules for work-related expenses. Pareto efficiency dictates a strict rule for marginal deductions along the income distribution. An immediate implication is a recipe for designing Pareto-improving reforms. We apply our theory and simulate a...

We analyze Pareto-efficient tax deduction rules for work-related expenses (e.g. housekeeping services, child care or elderly care). Pareto efficiency dictates a tight rule for how the rate of deductibility should vary with income and expenditures. An immediate implication is a recipe for...

Motivated by the EU Commission s suggested company tax reforms, this paper investigates how cross-border loss offset and formulary apportionment of a consolidated tax base affect the investment and transfer pricing behaviour of a multijurisdictional firm, and how they affect the behaviour of...
