To study the economic and welfare consequences of alternative time paths towards net zero CO2e emissions, we develop a multi-sector dynamic computable general equilibrium model of an open economy with heterogeneity in abatement costs across sectors and firms and with adjustment costs in the...

We employ the footloose capital model to examine and compare how two countries decide on their emission permits non-cooperatively under domestic and international emissions trading in the presence of capital mobility. We find that even if two countries are symmetric and have the same carbon...

Tax competition for mobile capital can undermine the attempts of governments to redistribute income from rich to poor. I study whether international tax coordination can alleviate this problem, using a general equilibrium model synthesizing recent contributions to the tax competition literature....

This paper examines the case for internationally coordinated indirect taxes on aviation (as a source of general revenue-not (necessarily) as a source of development finance). The case for such taxes is strong: the tax burden on international aviation is currently limited, yet it contributes...

This article covers the legal requirements regarding the use of renewable fuel. It covers the environmental impacts of using ethanol, cellulosic ethanol, and biodiese as fuel. It discusses the subsidies provided to encourage the use of biofuel. It concludes that the existing programs to...

Nearly all countries tax the domestic consumption of alcoholic beverages. However, the rates of taxation, and the tax instruments used, vary enormously between countries. This paper provides estimates, for a wide range of high-income and developing countries, of the consumer tax equivalents...

The social cost of carbon is the central economic measure for aggregate climate change damages and functions as a metric for optimal carbon prices. Previous literature shows that inequality significantly influences the level of the social cost of carbon, but mostly neglects a major source of...

In this paper I sketch out the rough contours of the challenge faced by the WTO in dealing with non-tariff measures (NTMs) as seen from the economic theories of trade agreements. The key questions for the WTO - the answers to which largely dictate the choice between shallow and deep approaches...

In both Europe and the United States, there has been much recent debate regarding whether, in response to the 2008 financial crisis, one should enact a financial transactions tax (FTT) or a financial activities tax (FAT) – commonly viewed as mutually exclusive alternatives. This article...

Tax collection is vital to maintain fiscal sustainability. According to a World Bank report, developing economies average 15% of Gross Domestic Product (GDP) in tax collections which is lower than that in advanced economies i.e. 40%. This inability of the developing economies recognizes weak...
