(Incidentally, the July Snowmass presentations regarding Integrated Assessment models of the effects of such emission-reduction policy plans, which I plugged in my preceding blog post, are now accessible to the public.)

But issues of competitiveness and how to address it have risen to the top in the climate change policy debate among politicians.      The Lieberman-Warner bill - would have required the president to determine what countries have taken comparable action to limit GHG emissions;  for imports of covered goods from covered countries, the importer would then have had to buy international reserve allowances – equivalent to a tariff.  (The same with some of the bill’s competitors such as the Bingaman-Specter “Low Carbon Economy Act” of 2007.) 

In theory, there is a possible legitimate role for border adjustments in facilitating a multilateral regime such as the Kyoto Protocol.  One might think of penalties on carbon-intensive imports:

1.      as sanctions to apply pressure on non-participants,

2.      as a calibrated “countervailing duty” to equalize a distortion that will otherwise see carbon-intensive activities migrate to less-regulated countries (a phenomenon known as leakage)   or

3.      as political reassurance to domestic firms worried about their international competitiveness.

If designed properly, they need not necessarily be inconsistent with the WTO (World Trade Organization).    There are precedents, most importantly (and most ironically) the famous/infamous shrimp/turtle case.

But U.S. politicians are unlikely to do it properly.   They may be unaware that the US is more likely to end up as the target of such tariffs than as the enactor – to end up as the defendant, rather than as the prosecutor.   The European Union is way ahead of us in cutting back GHG emissions under the Kyoto protocol, and its EC Directive earlier this year had similar language calling for penalties aimed at shirking competitors.   That’s us.  The difference between their provisions for dealing with shirkers and ours is that their system is already in operation, while for the time being, we are the shirkers.  So US politicians had better look before they leap on this one.

The Brookings Institution had a conference in June that was well-focused on this set of policy issues, organized by Lael Brainard.  Interested readers can link to the papers at Climate Change, Trade and Competitiveness: Is a Collision Inevitable ?    Mine was titled  “Addressing the Leakage/Competitiveness Issue In Climate Change Policy Proposals,” in the panel on Proposals to Deal with Leakages.   

 The issues are reminiscent of larger fears on the part of anti-globalizers — that the WTO and free trade are obstacles to environmental regulation more generally — fears that I think are largely misplaced.   With well-designed multilateral policies, we can work to protect the global environment while simultaneously preserving the economic advantages of free trade.

I am also working on a broader project to address the design of climate change policy architecture as part of the HPICA initiative at Harvard directed by Joe Aldy and Rob Stavins.

Ten years ago this summer, President Clinton’s Council of Economic Advisers, of which I was a Member, responded to requests from the Congress, which was then under Republican control, to explain in analytical terms what would be the economic effects of the Kyoto Protocol on climate change that had just been negotiated among the members of the UN Framework Convention on Climate Change.  Our response was a document called the Administration Economic Analysis.   It relied on some of the leading Integrated Assessment Models, and showed that the costs of Kyoto could be relatively low provided international trading of emission permits were freely allowed, and provided developing countries participated in the system.    Not zero costs, as wishful thinking by some techno-optimists would have it.  Not prohibitive costs, as some skeptics would have it.   But moderate costs — relatively low if measures could be implemented sensibly.

Integrated Assessment Models are designed to assess both the economic costs and the environmental benefits of action to reduce emissions of greenhouse gases.   For 15 years, the Energy Modeling Forum (EMF), under the leadership of John Weyant at Stanford University, has periodically brought together the modelers to compare results and exchange ideas.   It was gratifying when we discovered that the economic model we had used to estimate costs was near the middle of the pack of ten leading academic models according to the EMF, in terms of the estimated impact on energy costs  for example, contrary to suspicions that we must have low-balled the estimates.

Exactly ten years ago, in August 1998, I attended the Energy Modeling Forum’s annual workshop in Snowmass, Colorado, Climate Change Impacts and Integrated Assessment.   My assignment then was to explain the Administration Economic Analysis to this group.  Unlike most American economists, I believe that something along the lines of the Clinton-Gore version of Kyoto offers the most promising path to address the problem of Global Climate Change.
