Congress is likely to consider domestic climate change legislation during 2009, with a cap-and-trade system continuing to draw support from the Obama Administration and many leaders in Congress. Yet cap-and-trade regulations would take years for EPA to develop and implement, the desired price...

This paper investigates regional or international transfers as a means to prevent immigration into unemployment. We analyze a two-country model with free migration in which the rich country is characterized by minimum wage unemployment. Matching grants for investment in infrastructure are...

For any emission trading system (ETS) with quantity-based endogenous supply of allowances, there exists a negative demand shock, e.g. induced by abatement policy, that increases aggregate supply and thus cumulative emissions. We prove this green paradox for a general model and then apply it to...

Economic thought on climate policy as an instance of environmental regulation is strongly influenced by the principle of a uniform carbon price. Economists acknowledge that this principle breaks down in a second-best world with other distortions, such as taxes and market power in domestic and...

We analyze how a country pursuing a unilateral climate policy may contribute to a reduction in global CO2 emissions in a cost-effective way. To do so its system of energy taxes and subsidies must account for leakage of emissions from the domestic to the foreign economy. We focus on leakage...

Major carbon-pricing systems in Europe and North America involve multiple countries or states. Individual jurisdictions often pursue additional initiatives---such as unilateral carbon price floors, legislation to phase out coal, aviation taxes or support programs for renewable energy---that...

Using a discrete-continuous model that deals with both consumers' choice and usage of an environmentally differentiated product in a utility-consistent framework, this paper investigates welfare impacts of emission taxes, subsidies and ad valorem taxes/subsidies on a green market where consumers...

We analyze horizontal mergers when the acquirer holds a passive partial ownership stake (PPO) in the target firm prior to the merger. We show that a PPO reduces the minimal synergy level necessary to make a merger beneficial for consumers. It follows that an antitrust authority ignoring existing...
