This paper builds two simple general equilibrium models to demonstrate the equivalence between the Pigovian tax and the combination of a presumptive tax and an environmental subsidy. A presumptive tax is a tax that is imposed under the presumption that all production uses a dirty technology or...

The standard theory that the first-best tax on pollution is equal to marginal environmental damages has been extended in two directions. First, many polluting activities are difficult to tax because they are not market transactions, and so recent papers have shown that the same effects can be...

The United States Government recently concluded a year-long process to develop a range of values representing the monetized damages associated with an incremental increase in carbon dioxide (CO2) emissions, commonly referred to as the social cost of carbon (SCC). These values are currently used...

One country that tries to reduce greenhouse gas emissions may fear that other countries get a competitive advantage and increase emissions ("leakage"). Estimates from computable general equilibrium (CGE) models such as Elliott et al (2010a,b) indicate that 15% to 25% of abatement might be offset...
