A closer look at the Kerry-Lieberman cap-and-trade proposal
As with the Waxman-Markey bill (H.R. 2454), passed by the House of Representatives last June, there is now some confusing commentary in the press and blogosphere about the allocation of allowances in the new Senate proposal — the American Power Act of 2010 — sponsored by Sens. John Kerry (D-Mass.) and Joseph Lieberman (I-Conn.). As before, the mistake is being made of confusing the share of allowances that are freely allocated versus auctioned with (the appropriate analysis of) the actual incidence of the allowance value, that is, who ultimately benefits from the allocation and auction revenue.
In this essay, I assess quantitatively the actual incidence of the allowance value in the new Senate proposal, much as I did last year with the House legislation. I find (as with Waxman-Markey) that the lion’s share of the allowance value — some 82 percent — goes to consumers and public purposes, and only 18 percent accrues to covered, private industry. First, however, I place this in context by commenting briefly on the overall Senate proposal, and by examining in generic terms the effects that allowance allocations have — and do not have — in cap-and-trade systems.
The American Power Act of 2010
You may be wondering why I am bothering to write about the Kerry-Lieberman proposal at all, given the conventional wisdom that the likelihood is very small of achieving the 60 votes necessary in the Senate to pass the legislation (particularly with the withdrawal of Sen. Lindsay Graham (R-S.C.) from the former triplet of Senate sponsors). Two reasons. First, conventional wisdoms often turn out to be wrong (although I must say that the vote count on Kerry-Lieberman does not look good, with the current tally according to Environment & Energy Daily being 26 Yes, 11 Probably Yes, 31 Fence Sitters, 10 Probably No, and 22 No). Second, if the conventional wisdom turns out to be correct, and the 60-vote margin proves insurmountable in the current Congress, then when the Congress returns to this issue — which it inevitably will in the future — among the key starting points for Congressional thinking will be the Waxman-Markey and Kerry-Lieberman proposals. Hence, the design issues do matter.
The American Power Act, like its House counter-part, is a long and complex piece of legislation with many design elements in its cap-and-trade system (which, of course, is not called “cap-and-trade” — but rather “reduction and investment”), and many elements that go well beyond the cap-and-trade system (sorry, I meant to say the “reduce-and-invest” system). Perhaps in a future essay, I will examine some of those other elements (wherein there is naturally both good news and bad news), but for today, I am focusing exclusively on the allowance allocation issue, which is of central political importance.
Before turning to an empirical examination of the Kerry-Lieberman allowance allocation, it may be helpful to recall some generic facts about the role that allowance allocations play in cap-and-trade systems.
The role of allowance allocations in cap-and-trade systems
It is exceptionally important to keep in mind what is probably the key attribute of cap-and-trade systems: the particular allocation of those allowances which are freely distributed has no impact on the equilibrium distribution of allowances (after trading), and therefore no impact on the allocation of emissions (or emissions abatement), the total magnitude of emissions, or the aggregate social costs. (There are some caveats, about which more below.) By the way, this independence of a cap-and-trade system’s performance from the initial allowance allocation was established as far back as 1972 by David Montgomery in a path-breaking article in the Journal of Economic Theory (based upon his 1971 Harvard economics PhD dissertation). It has been validated with empirical evidence repeatedly over the years.
Generally speaking, the choice between auctioning and freely allocating allowances does not influence firms’ production and emission reduction decisions (although it’s true that the revenue from auctioned allowances can be used for a variety of public purposes, including cutting distortionary taxes, which can thereby reduce the net cost of the program). Firms face the same emissions cost regardless of the allocation method. When using an allowance, whether it was received for free or purchased, a firm loses the opportunity to sell that allowance, and thereby recognizes this “opportunity cost” in deciding whether to use the allowance. Consequently, the allocation choice will not — for the most part — influence a cap’s overall costs.
Manifest political pressures lead to different initial allocations of allowances, which affect distribution, but not environmental effectiveness, and not cost-effectiveness. This means that ordinary political pressures need not get in the way of developing and implementing a scientifically sound, economically rational, and politically pragmatic policy. With other policy instruments — both in the environmental realm and in other policy domains — political pressures often reduce the effectiveness and/or increase the cost of well-intentioned public policies. Cap-and-trade provides natural protection from this. Distributional battles over the allowance allocation in a cap-and-trade system do not raise the overall cost of the program nor affect its environmental impacts.
In fact, the political process of states, districts, sectors, firms, and interest groups fighting for their share of the pie (free allowance allocations) serves as the mechanism whereby a political constituency in support of the system is developed, but without detrimental effects to the system’s environmental or economic performance. That’s the good news, and it should never be forgotten.
But, depending upon the specific allocation mechanisms employed, there are several ways that the choice to freely distribute allowances can affect a system’s cost. Here’s where the caveats come in.
Some important caveats
First, as I said above, auction revenue may be used in ways that reduce the costs of the existing tax system or fund other socially beneficial policies. Free allocations forego such opportunities.
Second, some proposals to freely allocate allowances to electric utilities may affect electricity prices, and thereby affect the extent to which reduced electricity demand contributes to limiting emissions cost-effectively. Waxman-Markey and Kerry-Lieberman both allocate a significant number of allowances to local (electricity) distribution companies, which are subject to cost-of-service regulation even in regions with restructured wholesale electricity markets. Because the distribution companies are subject to cost-of-service regulation, the benefit of the allocation will ultimately accrue to electricity consumers, not the companies themselves. While these allocations could increase the overall cost of the program if the economic value of the allowances is passed on to consumers in the form of reduced electricity prices, if that value is instead passed on to consumers through lump-sum rebates, the effect can be to compensate consumers for increased electricity prices without reducing incentives for energy conservation. (There are some legitimate behavioral questions here about how consumers will respond to such rebates; these questions are best left to ongoing economic research.)
Third, “output-based updating allocations” can be useful for addressing competitiveness impacts of a climate policy on particularly energy-intensive and trade-sensitive sectors, but these allocations can provide perverse incentives and drive up the costs of achieving a cap if they are poorly designed. This merits some explanation.
An output-based updating allocation ties the quantity of allowances that a firm receives to its output (production). Such an allocation is essentially a production subsidy. While this affects firms’ pricing and production decisions in ways that can, in some cases, introduce unintended consequences and increase the cost of meeting an emissions target, when applied to energy-intensive trade-exposed industries, the incentives created by such allocations can contribute to the goal of reducing emission leakage abroad.
This approach is probably superior to an import allowance requirement, whereby imports of a small set of specific commodities must carry with them CO2 allowances, because import allowance requirements can damage international trade relations. The only real solution to the competitiveness issue is to bring key non-participating countries within an international climate regime in meaningful ways, an obviously difficult objective to achieve. (On this, please see the work of the Harvard Project on International Climate Agreements.)
Is the Kerry-Lieberman allowance allocation a corporate give-away?
Perhaps unintentionally, there has been some potentially misleading coverage on this issue. At first glance, about half of the allowances would be auctioned and about half freely allocated over the life of the program, 2012-2050. (In the early years, the auction share is smaller, reflecting various transitional allocations that phase out over time.) But looking at the shares that are auctioned and freely allocated can be very misleading.
Instead, the best way to assess the real implications is not as “free allocation” versus “auction,” but rather in terms of who is the ultimate beneficiary of each element of the allocation and auction, that is, how the value of the allowances and auction revenue are allocated. On closer inspection, it turns out that many of the elements of the apparently free allocation accrue to consumers and public purposes, not private industry. Indeed, my conclusion is that over the period 2012-2050, less than 18 percent of the allowance value accrues to industry.
First, let’s looks at the elements which will accrue to consumers and public purposes. Next to each allocation element is the respective share of allowances over the period 2012-2050:
I. Cost Containment
a. Auction from cost containment reserve, 3.1 percent
II. Indirect Assistance to Mitigate Impacts on Energy Consumers
b. Electricity local distribution companies, 18.6 percent
c. Natural gas local distribution companies, 4.1 percent
d. State programs for home heating oil, propane, and kerosene consumers, 0.9 percent
III. Direct Assistance to Households and Taxpayers
e. Allowances auctioned to provide tax and energy refunds for low-income households, 11.7 percent
f. Allowances auctioned for universal tax refunds, 22.3 percent
IV. Other Domestic Priorities
g. State renewable and energy efficiency programs, 0.6 percent
h. State and local agency programs to reduce emissions through transportation projects, 1.9 percent
i. Grants for national surface transportation system, 1.9 percent
j. Auctioned allowances for Highway Trust Fund, 1.9 percent
k. Domestic adaptation, 1.0 percent
l. Rural energy savings (consumer loans to implement energy efficiency measures), 0.1 percent
V. International Funding
m. International adaptation, 1.0 percent
VI. Deficit Reduction
n. Allowances auctioned for deficit reduction, 7.4 percent
o. Remaining allowances auctioned to offset bill’s impact on deficit, 6.1 percent
Next, the following elements will accrue to private industry, again with average (2012-2050) shares of allowances:
I. Allocations to Covered Entities
a. Energy-intensive, trade-exposed industries, 7.0 percent
b. Petroleum refiners, 2.2 percent
c. Merchant coal-fired electricity generators, 2.2 percent
d. Generators under long-term contracts without cost recovery, 0.9 percent
II. Technology Funding
e. Carbon capture and sequestration incentives, 3.8 percent
f. Clean energy technology R&D, 0.7 percent
g. Low-carbon manufacturing R&D, 0.3 percent
h. Clean vehicle technology incentives, 0.3 percent
III. Other Domestic Priorities
i. Manufacturing plant energy efficiency retrofits, 0.1 percent
j. Compensation for early action emissions reductions prior to cap’s implementation, 0.1 percent
The bottom line? Over the entire period from 2012 to 2050, 82.6 percent of the allowance value goes to consumers and public purposes, and 17.6 percent to private industry. Rounding error brings the total to 100.2 percent, so to be conservative, I’ll call this an 82/18 percent split.
Moreover, because some of the allocations to private industry are — for better or for worse — conditional on recipients undertaking specific costly investments, such as investments in carbon capture and storage, part of the 18 percent free allocation to private industry should not be viewed as a windfall.
I should also note that some observers (who are skeptical about government programs) may reasonably question some of the dedicated public purposes of the allowance distribution, but such questioning is equivalent to questioning dedicated uses of auction revenues. The fundamental reality remains: The appropriate characterization of the Kerry-Lieberman allocation is that about 82 percent of the value of allowances go to consumers and public purposes, and 18 percent to private industry.
Comparing the Kerry-Lieberman 82/18 split with recommendations from economic analyses
The 82-18 split is roughly consistent with empirical economic analyses of the share that would be required — on average — to fully compensate (but no more) private industry for equity losses due to the policy’s implementation. In a series of analyses that considered the share of allowances that would be required in perpetuity for full compensation, Bovenberg and Goulder (2003) found that 13 percent would be sufficient for compensation of the fossil fuel extraction sectors, and Smith, Ross, and Montgomery (2002) found that 21 percent would be needed to compensate primary energy producers and electricity generators.
In my work for the Hamilton Project in 2007, I recommended beginning with a 50-50 auction-free-allocation split, moving to 100 percent auction over 25 years, because that time-path of numerical division between the share of allowances that is freely allocated to regulated firms and the share that is auctioned is equivalent (in terms of present discounted value) to perpetual allocations of 15 percent, 19 percent, and 22 percent, at real interest rates of 3, 4, and 5 percent, respectively. My recommended allocation was designed to be consistent with the principal of targeting free allocations to burdened sectors in proportion to their relative burdens, while being politically pragmatic with more generous allocations in the early years of the program.
So, the Kerry-Lieberman 82/18 allowance split (like the 80/20 Waxman-Markey allowance split) turns out to be consistent — on average, i.e. economy-wide — with independent economic analysis of the share that would be required to fully compensate (but no more) the private sector for equity losses due to the imposition of the cap, and consistent with my Hamilton Project recommendation of a 50/50 split phased out to 100 percent auction over 25 years.
The path ahead
Going forward, many observers and participants in the policy process may continue to question the wisdom of some elements of the Kerry-Lieberman proposal, including its allowance allocation. There’s nothing wrong with that.
But let’s be clear that, first, for the most part, the specific allocation of free allowances affects neither the environmental performance of the cap-and-trade system nor its aggregate social cost.
Second, we should recognize that the legislation is by no means a corporate give-away. On the contrary, 82% of the value of allowances accrue to consumers and public purposes, and some 18% accrue to covered, private industry. This split is roughly consistent with the recommendations of independent economic research.
Finally, it should not be forgotten that the much-lamented deal-making for shares of the allowances for various purposes that took place in the deliberations leading up the announcement by Senators Kerry and Lieberman was a good example of the useful, important, and fundamentally benign mechanism through which a cap-and-trade system provides the means for a political constituency of support and action to be assembled, without reducing the policy’s effectiveness or driving up its cost.
