Unions appear to have an aversion to wage disparities among their members, leading to wage compression. This paper analyses the consequences of this for income tax policy. In a two-sector general equilibrium model we highlight the tradeoff between correcting the resource misallocation created by...

The authors provide a broad overview of economic aspects of commodity taxation, focussing in particular on theory and on policy applications in OECD countries. Some major papers in public economics have discussed whether these taxes should be levied at a uniform rate, or whether different...

The incidence and efficiency losses of taxes have usually been analysed in isolation from public expenditures. This negligence of the expenditure side may imply a serious misperception of the effects of marginal tax rates. The reason is that part of the marginal tax may in fact be payment for...

Addressing extensive labour supply responses, the literature has established a case for larger transfers to the working poor than to even poorer non-working people. This paper casts new light on this result. I argue that the result hinges crucially on the labour supply responses of people in...

Non-linear income taxes and linear commodity taxes are analysed when people differ with respect to ability, high-skilled agents have heterogeneous preferences, and neither individual abilities nor preferences are observable. The paper highlights how informational constraints may motivate...

A strong case for public provision of certain private goods has been established for an economy in which individuals have homogeneous preferences but differ in skill levels. There has been a critique of this model/mechanism arguing that heterogeneous preferences at a given skill level would...

In 1999 the EU abolished duty-free on intra-EU travel, whilst other countries still retain duty-free shopping for international travellers. We address several aspects of duty-free trade, including effects on consumption, revenue and price-setting. From a global perspective we identify the...

When a public good is excludable it is possible to charge individuals for using the good. We study the role of prices on excludable public goods using an extension of the Stiglitz-Stern version of the Mirrlees optimal income tax model. Our discussion includes both the case where the public good...
