Much of the literature on externalities has considered taxes and direct regulation as alternative policy instruments. Both instruments may in practice be imperfect, reflecting informational deficiencies and other limitations. We analyse the use of taxes and regulation in combination, to control...

Alcohol consumption is associated with costs to society due to its impact on crime and health. Tax can lead consumers to internalise these externalities. We study optimal corrective taxation in the alcohol market. We allow for the fact that the externality generating commodity (ethanol) is...

This paper presents a theoretical gravity model of trade in which foreign aid is considered as a transfer instead of being part of the trade cost, as it has been previously done in the related literature. We argue that the usual specification leads to invalid out-of-sample predictions, biased...

A substantial amount of aid to developing countries is given to the government, or goes through the budget, meaning it should have an impact on government fiscal behaviour (particularly on government spending). The few existing cross-country empirical studies on the effects of aid on government...

The main argument of this paper is that there is considerable heterogeneity in the way aid can shape tax performance in developing countries: through behavioural effects, donor conditionality, recipient policy reform and technical assistance; and these effects are country-specific. We investigate...

Past research on aid and growth is flawed because it typically examines the impact of aggregate aid on growth over a short period, usually four years, while significant portions of aid are unlikely to affect growth in such a brief time. We divide aid into three categories: (1) emergency and...
