This paper studies the design of sin taxes when firms exercise market power. We outline an optimal tax framework that highlights how market power impacts the efficiency and redistributive properties of sin taxation, and quantify these effects in an application to sugar-sweetened beverage...

This paper concerns international coordination of environmental taxation.The main contribution of the paper is to provide a frame-work for dynamiccost benefit analysis of environmental tax reforms in a global economy withtransboundary environmental problems. We show that the welfare effects...

We estimate the marginal external congestion cost of motor-vehicle travel for Rome, Italy, using a methodology that accounts for hypercongestion (a situation where congestion decreases a road's throughput). We show that the external cost - even when roads are not hypercongested - is substantial,...

Despite favourable ecological and economic results, many developing countries have not yet adopted an integrated pesticide management (IPM). Given rising marginal costs and diminishing marginal benefits from IPM technology transfer, an optimal control framework is used to identify optimal rates...

We analyze various normatively determined distributions of language rights in multilingual settings. A general model for the analysis of language rights over time in a model with overlapping generations is set up. This model is then first used to find efficient allocations of rights in the...

Contrary to the case considered in literature, the experience of developing countries indicates that the tariff reforms have not been revenue neutral due to the heavy dependence of developing countries on trade taxes and pervasive tax evasion. In contrast to the plausibility of a welfare loss...
