When government needs more revenue than is available from a pollution tax rate equal to marginal environmental damage, our intuition tells us to raise the tax on the clean good above zero and to raise the tax on the dirty good above that first-best Pigouvian rate. Yet new results suggest that...

A carbon tax has been widely discussed as a way of reducing fossil fuel use and mitigating climate change, generally in a static framework. Unlike standard goods that can be produced, oil is an exhaustible resource. Parts of its price reflects scarcity rents, i.e., the fact that there is limited...

This paper develops a micro-founded city systems model with an endogenous number of cities to explore whether local governments establish the optimal city size when production processes involve environmental pollution. Our analysis delivers two key insights. First, if an optimal scheme to...

In this paper, we assess the distributional impact of introducing a carbon tax in Poland. We apply a two-step simulation procedure. First, we evaluate the economy-wide effects with a dynamic general equilibrium model. Second, we use a microsimulation model based on household budget survey data...

There is a consensus among economists that a carbon tax is the best approach for addressing the effects of CO2 emissions on the global climate. However, past international agreements on climate change instead specify caps on emissions (a quantity target) for each country. This paper explores...

We review the optimal pattern of carbon emission abatements across countries in a simple multi-country world. We model explicitly the fact that the atmosphere is a public good. Within this framework we establish conditions for it to be necessary for optimality that the marginal cost of abatement...

A two-region model is presented in which an imperfectly competitive firm produces a good with increasing returns at the plant level, and in which shipping costs exist between the two markets. Production of the good causes local pollution, and regional governments can levy pollution taxes or...

We present an integrated framework to understand the emissions impact of unilateral overlapping policies within a carbon-pricing system. "Internal carbon leakage" captures emissions displacement within the system (e.g., due to greater product imports from a neighbouring country). The waterbed...

Environmental federalism refers to the debate over the "optimal" level of government at which to delegate environmental policymaking. Although this issue receives widespread attention across the globe, opinions run the gamut. The diversity of views plays out in practice as well as different...
