The zombie economics of austerity in Australia (updated again)

February 16th, 2012 128 comments

Yesterday’s Fin ran a piece from Stephen Kirchner and Robert Carling of the Centre for Independent Studies, under the headline “Give austerity a chance” which was a pretty accurate summary of the contents. It’s paywalled, but you may be able to read it by clicking here. The piece relies almost exclusively on the work of Alberto Alesina and his colleagues, promoting the zombie idea of expansionary austerity. As I pointed out here, the most influential of these pieces by Alesina and Ardagna, is riddled with errors, at least as it applies to Australia.

Although Kirchner is a blogger himself, he and his co-author could be forgiven for missing my post. But Alesina’s work is probably the most-refuted piece of economic analysis put out (though never published in a peer-reviewed journal) in recent decades. It’s been demolished not only by the usual suspects like Krugman and DeLong (and me), but by the Economist, the IMF and even by one of Alesina’s own co-authors, Roberto Perotti.

Charitably assuming that Kirchner and Carling had managed to miss just about every publication on the question of austerity in the last year, could they not have spent 30 seconds with Google before hitting “Send”? A search on Alesina+austerity reveals a torrent of criticism, none of which they mention.

It is hard to know which is worse – the possibility that Kirchner and Carling, presented by the CIS as expert economists, were ignorant of all this, or the alternative hypothesis that they knew it and decided not to mention it. Either way, it’s an appalling breach of elementary standards of research.

I’m pretty sure the facts have been brought to the attention of Kirchner and Carling. The honest thing to do would be to write to the Fin pointing out that the work on which they relied was, at best, highly controversial. If Kirchner, Carling and the CIS are unwilling to do this, we can draw the conclusion that they cannot be trusted in anything they write.

Update Sinclair Davidson at Catallaxy has a lengthy reply, but the sole substantive criticism is that contrary to my parenthetical remark, Alesina and Ardagna did finally publish a peer-reviewed paper in 2010. But the work that was actually influential was done back in the 1990s. I’ll republish my blog post pointing out what a shoddy job that paper in describing developments in Australia. Davidson’s piece is notable for the lack of any substantive defence of Alesina’s work, and also for this , offered in response to my observation that the research in question had been comprehensively demolished by the IMF among many others

Fancy that – cutting edge research into a highly politicised aspect of public policy is “controversial”. Does Quiggin think AFR readers are so dumb they wouldn’t realise that?

So, next time you read an opinion piece from the CIS you can safely assume the caveat lector “This research is probably discredited, the authors almost certainly know it, but, if so, they’re not going to tell you”.

No one expects opinion pieces to be “fair and balanced”, but if you are going to rely on work that has been subject to serious and credible criticism, you should at least point out the main criticisms and (if possible) say briefly why you think they don’t stand up. As an example, Wilkinson and Pickett’s The Spirit Level produces some striking evidence of relationships between inequality and bad social outcomes.. This work has been subject to a lot of criticism, not fatal in my view, but enough that it needs to be mentioned. I did this when I cited the work in Zombie Economics and then at greater length here

Further update While still not disputing any of the substantive points I’ve raised, Davidson digs deeper on the question of whether the original Alesina and Ardagna work was published in a peer-reviewed journal. The work was published in Economic Papers, which does not take unsolicited submissions. Rather the editors commission pieces, or you can propose a piece to them. That is, this is, as the webpage says, a policy forum, not an academic journal. Standard practice for publications of this kind is for the editors to approve (or return for revision, or, very rarely, reject) the pieces they’ve commissioned. This isn’t peer-review in the normal sense. I’ve always assumed that Economic Papers follows the standard practice in this respect, but Davidson is welcome to check it out, if he cares enough.

As a PS, I couldn’t resist checking a 700-comment thread on the US elections. I shouldn’t link, but I will. While there is plenty of not-so-innocent amusement to be had, what struck me was that most of the commenters appear to be creationists – the handful holding up the flag for evolution are getting hammered.

Expansionary austerity: some shoddy scholarship (repost)

February 10th, 2012 37 comments

I’ve just read ‘Tales of Fiscal Adjustment’ by Alesina and Ardagna, which appears to be the founding text for the idea of expansionary austerity. The level of scholarship, at least as it applies to Australia (which is their first illustration) is exceptionally poor, to the extent that it requires a rescuscitation of the ancient Internet tradition of Fisking. I’m going to quote excerpts from their text (about 50 per cent of the total), and intersperse them with my comments.

Solar rises, nuclear falls

January 5th, 2012 119 comments

My piece for the National Interest is now up. It ran under the headline “The end of the nuclear renaissance”, but that’s only half the story and probably the less interesting half. The real news of 2011 was the continued massive drop in the price of solar PV, which renders obsolete any analysis based on data before about 2010. In particular, anyone who thinks nuclear is the most promising candidate to replace fossil fuels really needs to recalibrate their views. There’s a case to be made for nuclear as a backstop option, but it’s not nearly as strong as it was even two years ago.

Occupied interview

November 1st, 2011 28 comments

A week or so ago I did an interview by Skype videolink with Taryn Hart of Occupied Media, talking about the issues raised by Occupy Wall Street. It’s now available online. I never watch myself on video, but I did listen to the whole thing and, allowing for a fair number of ums, ahs, and circumlocutions, I think the questions gave me the chance to state my ideas, and in some cases to work out on the spot what I thought about various issues.

Tea Party didn’t mind bailing out Wall Street, only Main Street

October 19th, 2011 21 comments

My Fin column from last week is over the fold. It’s mainly about the Occupy Wall Street protests, but in this post I want to stress a misleading comparison with the Tea Party. It’s often suggested that the Tea Party arose in response to the bailout of Wall Street, and until I checked, I had somewhat accepted this claim, even if it was obvious that the protest served the interest of its supposed targets.
In reality, though, there is no truth at all to this claim. To quote from the article

The first Tea Party protests were held in February 2009, shortly after the inauguration of President Obama, and four months after the Bush Administration bailed out the banks. The event that did most to drive the Tea Party protests was a rant delivered by journalist Rick Santelli from the floor of the Chicago Mercantile Exchange. To the cheers of traders, Santelli denounced bailouts, but not the bailout of the financial sector. His ire was directed against attempts to help struggling homeowners refinance mortgages taken out during the real estate bubble.

I used to see the Tea Party as having had some genuine elements, but co-opted by Wall Street and the Repubs. Now, it’s clear that Repub activists ran the show from day one. Some individual participants may have been sucked in by anti-bailout rhetoric but the organizers were on the side of the 1 per cent all along.

Time for a new tailor

August 17th, 2011 19 comments

It’s rare to take on Paul Krugman in an argument and win, and I agree with him most of the time anyway (these two facts are correlated!). So, this is the first time, and will probably be the last, when I can claim a win in such an argument.

Krugman has long criticised the eurozone on the grounds that it is not an optimal currency area and that the European Central Bank must therefore pursue an unsatisfactory “one size fits all” policy, too contractionary for economies that are doing badly and too expansionary for those that are doing well. Back in February, I argued that in fact ECB policy was “One size fits nobody” and that even Germany was vulnerable to its contractionary effects.

The latest statistics suggest that German growth was already stalling then. Today, Krugman is also pointing to a “one size fits none” policy.

At this point, it’s time for a suit of clothes, and that means a new tailor. And, in that respect, the bad news may have a silver lining.

My evidence on the carbon price

August 15th, 2011 44 comments

Last week I appeared, by videolink, before the Senate Committee on New Taxes, to talk about the government’s carbon price and compensation package. I made some dot points, over the fold.

The inquiry was interesting, with one Senator insisting that the carbon price was different from the GST because, under the GST, businesses could claim their inputs and therefore didn’t have to pay anything. I tried to suggest that this was only true for businesses that didn’t add any value (it is, after all, a value added tax), but to no avail.

Inequality is bad for (almost) everyone

August 12th, 2011 30 comments

Yves Smith, whose Naked Capitalism blog is essential reading, is guestblogging for Glenn Greenwald this week. Her latest post sums up a lot of evidence on the adverse effects of inequality, and includes a reference to a post of mine. In summary, the huge growth of inequality in the US has harmed everyone below the 90th percentile of the income distribution in the obvious way – they get a smaller share of a cake that isn’t growing very fast, and has been shrinking since the crisis began

But even people above that level, but outside the top 1 per cent are worse off in important ways. They’ve maintained or increased their share of national income, but they aren’t rich enough to insulate themselves fully from the adverse consequences of living in a highly unequal society. Yves sums up a bunch of the evidence on thsi.

Finally, there are those in the top 1 per cent of the income distribution, now pulling in 25 per cent of all income. Members of this group can, if they choose, ignore the collapse of the society outside their gated communities, and focus on enjoying the wealth they extract from it. On recent evidence, that’s what they (or at least their political representatives) are doing, while also managing a very effective set of divide and rule tactics for the rest of the population.

What to do about the ratings agencies

August 7th, 2011 66 comments

S&P’s decision to downgrade US Treasury bonds from AAA to AA+ has elicited various reactions, some of which I’ll doubtless repeat here. Obviously, S&P has no particular expertise (apparently it couldn’t even get the arithmetic right) and based on its historical and continuing performance, its opinions ought to carry no particular weight with anybody (they say so themselves, when under pressure over obvious cases of misrating, asserting that they are merely offering an opinion).

On the other hand, it’s also pretty obvious (and even more so after the Repubs successful use of the debt ceiling to force Obama to abandon any call for tax increases along with the cuts they both wanted) that the US has some fairly intractable problems in dealing with its (technically quite manageable, but still substantial) public debt. Finally, as I said last time I discussed this, a decision of this kind (including a decision to maintain AAA ratings) is inherently political

There are two reasons why S&P’s choice of rating matters more than, say, my own opinions on the matter
* First, a lot of investors still pay attention to ratings agencies, for whatever reason
* Much more importantly, agency ratings are embedded in global regulations concerning prudent management of investment. If a second major agency were to join S&P in downgrading, large numbers of institutions would be debarred, under existing rules, from investing in Treasury bonds

That’s clearly unsustainable, so what will happen?

Believing Barry O’Farrell could cost you “up to” 100 IQ points

August 4th, 2011 25 comments

The NSW government has released a a frothing at the mouth press release claiming that a carbon price will devastate the economy. As Mary McCarthy would say, every single word in it is a lie, including “a” and “the”. Top billing has to go to that old favorite of shonky advertisers “up to”, as in a carbon price will ” force up electricity prices for NSW households by up to $498 a year.” The Commonwealth Treasury modelling, which I’ve checked, gives an average cost increase of $3.30 or about $170 a year.

Although the analysis is attributed to NSW Treasury, they apparently weren’t hackish enough for the government, which had to go to Frontier Economics to get the answers they wanted. I’m waiting to see the report, but in the meantime, my reactions to the press statement are over the fold

Don’t look at the bank behind the curtain

July 17th, 2011 19 comments

The political impregnability of Rupert Murdoch and NewsCorp has always been one of those facts about the world that seemed regrettable but eternal. By contrast, the ability of the banks to emerge from their near-destruction of the world economy richer and more politically powerful than ever before certainly took me by surprise when it happened (partly motivating my change in title from “Dead Ideas” to “Zombie Economics”). John Emerson pointed out the other day that the head of risk management at Lehman Brothers, arguably the most egregious individual failure among the thousands of examples, was just appointed to a senior position at the World Bank.

But now it seems there is just a chance that the curtain might be swept away from even these wizards. The emerging theme in commentary is the corrupt culture of impunity represented by the press hacking scandal, MP expenses and the banks (here’s UK Labour leader Ed Miliband pulling them all together).

If Labor could tie the Conservative-Liberal austerity package to the protection of the systemically corrupt banking system, they would have the chance to put Nu Labour behind them (I noticed Blair has already credited Brown with killing the brand). Instead of putting all the burden on the public at large, they could force those who benefited from the bubble to pay for the cleanup. The two main groups are the creditors who lent irresponsibly, counting on a bailout and should now take a long-overdue haircut and high-income earners who benefited, either directly or indirectly, from the huge inflation in financial sector income.

I know it seems hopelessly naive to think the banks could ever be brought to heel. But they were, for decades after the Depression. And as impregnable as they look today, Newscorp looked just as impregnable three weeks ago, as did the CPSU and the apartheid regime in South Africa thirty years ago.

Of course this spring moment won’t last long. But perhaps there is enough momentum that it won’t be exhausted by Murdoch alone.

How to create a world-class university

July 11th, 2011 37 comments

The Grattan Institute is advertising a lecture on “How to create a world-class university” by Andrew Hamilton, VC of Oxford and previously Provost at Yale. As the ad says, “Hamilton has been a leader in two universities that are world class by any measure”.

Still, if we take his experience as representative the obvious answer to the question is of how to create a world-class university is “found it in 1700, or preferably earlier”. Hamilton may have some significant achievements, but the creation of a world class university doesn’t appear to be among them.

That’s a snark, but it conceals a serious point. The fact is that (with a handful of marginal exceptions) the leading universities in most developed countries, including the US, UK and Australia, are those that were leading universities in 1900. There is very little evidence to suggest that anything done by a vice-chancellor or provost can achieve more than marginal improvements in the relative ranking of a new university. Conversely (and I won’t name the Australian examples I have in mind) even spectacularly bad management can’t do much to damage a university that has been around for 100 years or more.

That in turn means that common assumptions about the benefits of competition in the university sector are almost entirely wrong. In the absence of effective market mechanisms by which well-run firms prosper and grow while badly-run firms shrink and die, competition is essentially meaningless.

The expansion of competition between Australian universities has led to huge spending on marketing and advertising, and the growth of a large supporting bureaucracy, but it’s done nothing to improve standards.

Carbon tax – instant reax

July 10th, 2011 48 comments

The proposed carbon tax is a substantial improvement on the heavily compromised emissions trading scheme agreed between the Rudd government and the Opposition under Malcolm Turnbull. Although there is substantial compensation for emissions-intensive industry it is temporary and based on historic emissions level, so that the incentive to reduce emissions is not compromised. The design of the compensation package for households is also welcome.

The government has avoided the temptation to pretend that everyone will be better off, and has taken the reasonable position that high income households do not need to be compensated for the introduction of necessary reforms. This has permitted the very welcome measure of raising the income tax threshold and thereby taking more than a million low-income workers out of the income tax system.

While the primary focus of the package is, correctly, on the imposition of a price on carbon emissions, there are a range of supporting measures designed to encourage energy efficiency and innovation. On the whole, these seem more carefully designed than the measures introduced under previous governments.

Giving up on the Murray Darling Basin

June 3rd, 2011 15 comments

The Risk and Sustainable Management Group, which I lead at the University of Queensland, launched our Annual Report for 2010 last night (link to large PDF coming soon). I’ll quote from the Foreword

As 2009 drew to a close, it seemed reasonable to expect that 2010 would see a resolution of the Australian political debate over the two environmental issues central to the work of the Risk and Sustainable Management Group: climate change and the management of the Murray–Darling Basin.

In the event, neither of these issues was resolved. The bipartisan agreement in support of an emissions trading scheme collapsed, and the policy was abandoned by the government. Following the August 2010 election, the government restated its support for a carbon price, but the main short-term focus was on the idea of a carbon tax.

Developments in water policy were equally confused. Under the Water Act 2007, passed by the Commonwealth Parliament with bipartisan support, the Murray Darling Basin Authority (MDBA) was required to produce a plan for the sustainable management of the Basin. The release of the Basin Plan was delayed by the election. The MDBA produced a Guide to the Proposed Basin Plan in October 2010 which met with a very hostile response, with copies of the Guide being burned at public meetings of irrigators. The Draft Plan is still under development.

I’m feeling a bit more hopeful about carbon prices than when I wrote that. Labor, Greens and the Independents seem to be holding together, and the public debate shows some increasing recognition that Abbott is an opportunistic hack and that while preferring prejudice to science may make for good talkback radio, it is not a good basis for public policy.

By contrast, the situation regarding the Murray Darling Basin has gone from bad to worse to pretty much hopeless. We had everything needed for a plan that made just about everyone better off: more water for the environment, a good deal for farmers who wanted to switch out of irrigation, no compulsory acquisition, and enough spare money sloshing into country towns to more than offset any reduction in agricultural output. Instead, the process was spectacularly mishandled, most notably by the Murray Darling Basin Authority, who managed to scare everyone into thinking the government was about to confiscate their water. That handed power back to the most reactionary irrigator lobby groups who just want to stay on the old, unsustainable, path as long as possible, while extracting as much money as they can from the public purse. The release yesterday of the Windsor Report suggests that they will get their wish. The central point of the report is that the government should abandon all “non-strategic” purchases of water, while pouring even more money into so-called “water-saving” schemes, which will cost 5-10 billion while delivering little if any additional water.

Perhaps there is a way back from this but I can’t see it at present. For the next couple of years, at least, I plan to give up (or at least scale down) my work on the Basin and focus on more tractable problems like stabilising the global climate, saving the Great Barrier Reef and fixing financial markets.

UK leading the way

May 30th, 2011 19 comments

The announcement by the UK government (Conservative-LibDem coalition) that it would aim to reduce CO2 emissions by 50 per cent, relative to 1990 levels, by 2025 has had a significant impact on the Australian debate and is likely to have a greater impact as time goes on.

In part this reflects the fact that, understandably if not entirely justifiably, Australians pay a lot more attention to news and ideas from the UK and US than from, say, France or Germany. The British announcement cuts the ground from under many of the claims being made by the denial/delusion/delay lobby in Australia.

* The idea that “Australia risks getting out in front of the world” is obviously false. Even assuming we get a carbon tax, leading on to an emissions trading scheme later this decade, we will be a decade or so behind the UK and other EU countries, which introduced an ETS in 2005

* The view that it is impossible, in a modern economy to reduce emissions substantially without a radical reduction in economic activity is obviously not shared by the UK government which (unlike the critics) has actually done the analytical work required to show that large reductions can be achieved at very little economic cost, and is now implementing the required policy. I’ve demonstrated this point over and over on this blog, and the negative responses have amounted to little more than “La, la, I’m not listening”, but hopefully a practical demonstration will have more effect

* As part of the longstanding intellectual trade with the UK, we get a regular flow of delusionist speakers like Lord Monckton out here (fair’s fair, we did send them Clive and Germaine after all). Demolition jobs like this one, from a leading British Tory, might make their audiences a bit more sceptical

What is central bank independence? (Updated)

Linking to Bennett McCallum with some puzzlement a while back, Brad DeLong asked why a higher inflation target could be seen as undermining central bank independence. I’m with McCallum on the analysis, but not on the policy conclusion. A higher inflation target would reduce central bank independence, and a good thing too.

Swan on Keynesian policy

April 11th, 2011 27 comments

Wayne Swan has a Fabian Essay defending the Keynesian credentials of the Rudd and Gillard government. The central argument is sound enough

if we are going to be Keynesians in the downturn, we have to be Keynesians on the way up again. That means a speedy return to surplus.

But there are a couple of big problems. The first is one of timing. The 2009-10 Budget, which included a large deficit as a Keynesian stimulus, proposed a return to surplus by 2015-16. This was seen at the time as quite ambitious – most developed countries have no obvious path back to surplus.

Nevertheless, by May 2010, with economic conditions much stronger than expected, it seemed as if the government had not been ambitious enough and the target date was brought forward to 2012-13.

Over the past year, however, the economic news, both locally and globally, has mostly been bad, with natural disasters producing short-term shocks, and the US and Europe mired in heavy debt and sluggish recovery. The economy has slowed a bit and tax revenue has fallen short of expectations. Unsurprisingly, on the government’s current policy settings, the return to surplus would be delayed, though probably still ahead of the original 2015-16 target.

From a Keynesian point of view, that’s exactly what should happen. Although the slowdown isn’t enough to justify an active fiscal stimulus, the standard Keynesian prescription would be to allow the automatic stabilizers to work, smoothing the path back to full economic recovery. Unfortunately, that’s not what the government is doing.

Financial transactions tax letter

April 5th, 2011 12 comments

From my incoming email

Groups across the world are inviting economists who are qualified by post-graduate degree (Master or PhD) to sign a letter in support of a financial transactions tax (see below). The goal is 1000 signers by Friday, April 8th.
Economists can sign the open letter by entering their details in the comments box at this link: or emailing euderzo@oxfam.org.uk.

Last year, 350 economists from all over the world signed a letter in support of a financial transactions tax, and over the past year there has been significant political movement towards implementing the FTT in Europe and some other countries. The campaign for the so-called ‘Robin Hood Tax’ is now hugely popular in many countries (www.robinhoodtax.org). The French have made an FTT a priority for their presidency of the G20 and there is a real chance of a breakthrough in the coming six months.

I’ve also had some contact with the organizers who would like some Australian academic economists (I take this to mean having an academic position in an Australian econ department) who would state their support as a group. If any of my readers fall into that category, please email me.

The fruitpickers lament

March 31st, 2011 52 comments

Way back in the 1970s, I spent a couple of short spells as an unemployed layabout, one of which was ended when I took a job as a fruitpicker, making (IIRC) $2 a day, which even then wasn’t food money (I wasn’t very good at it). Fortunately, the job included some basic accommodation and all the blackberries you could eat. And, even then the whinging from employers who claimed to be unable to get enough pickers was an old story.

Now, I see Tony Abbott is pushing the same line, wanting to stop dole payments in any district where there are (claimed to be) vacant fruitpicking jobs. After four decades of this stuff, we ought by now to have some actual evidence. So, I have a few questions

First, has there ever been occasion when significant volumes of fruit have gone unpicked because of a shortage of pickers? [1]

Second, has there been any occasion on which demand for fruitpickers has been enough that a person with no prior experience could make substantially more than the minimum wage (currently about $15/hour). ? [2]

And if, as I strongly suspect, the answer to both questions is No, what does that tell us about the expectations of the whinging employers. (I suggest, a ready supply of below-minimum wage workers, available on demand when needed, and ready to be sacked the moment they are not)

fn1 Not a strike, or some particular farmer so objectionable that all ir workers quit

fn2 I know that experienced pickers can do a bit better than this, but that’s not the relevant issue here.

What should the RBA be doing?

March 23rd, 2011 45 comments

My son called the other day to say I’d been mentioned in the Fin as a possible candidate for the the Board of the Reserve Bank. If I were a serious contender, this would be the cue for me to adopt a pose of grave silence on all policy issues, interspersed by gnomic observations to be pored over for their inner meaning. I’m not a serious contender (even if it’s nice to be thought of as someone who might be) so this seems to be a good time for unsolicited advice to whoever gets appointed.

In the short term, I’m pretty happy with the settings of macroeconomic policy. The Rudd government and the RBA got the monetary and fiscal stimulus right in 2009, and the move back to fiscal surplus and neutral settings for monetary policy has been paced appropriately (the government’s insistence on relying on spending cuts rather than scrapping the last stage of the tax cuts promised in 2007 was a big mistake in terms of budget policy, but that’s a different issue).

My concern is rather with longer-term issues arising from the GFC. First, it no longer makes sense to separate monetary and fiscal policy as sharply as was done in the pre-2007 period, given that, in any real emergency, the two will have to work together. That doesn’t imply doing away with central bank independence (we’ve had an independent central bank since the RBA was established) but it does imply a degree of co-ordination between RBA and Treasury more like the relationship that prevailed before the 1990s.

Second, the inflation targeting approach, based on Taylor rules, failed globally in the leadup to the crisis and during the crisis. An important lesson (which Stephen Bell and I, among others, pointed out before the crisis) is that low and stable inflation rates do not imply a stable economy. In fact, they may contribute to the growth of asset price bubbles (what Minsky terms the shift from hedge to speculative finance). There’s still a lot of room for discussion about what should replace inflation targeting, but full employment needs to be given more weight than in the past.

Third, the separation between monetary policy and prudential policy needs to be re-examined. Everything went well in Australia, but the problems overseas suggest we need to take another look at this.

Changing places

March 5th, 2011 67 comments

As long-term readers here will know, I argued for quite a few years that, of the possible ways of putting a price on carbon, an emissions trading scheme was preferable to a tax (I set out my position here). But following the collapse of the Rudd government’s ETS deal with Malcolm Turnbull, and Rudd’s ultimately disastrous failure to call a double dissolution on the issue, I changed my mind.

This was partly because of changed circumstances, and partly because of a reconsideration of the politics surrounding compensation. In both cases, the driving force was the massively complicated set of free permits, exemptions and cash handouts with which the final ETS was saddled, nearly all of these going to large-scale emitters. I had seen the possibility of a limited issue of free permits as an advantage of an ETS, but now I think it was actually a weakness. And in political terms, the inordinate complexity of the CPRS made a strong case for something simple and comprehensible, where everyone understood that consumers would ultimately pay the price of carbon. Unlike with emissions permits, everyone understands that a tax on producers will be passed on (partially in the short run, and totally in the long run) to consumers, and therefore that any offsets or compensation should be directed primarily at consumers.

So, I now think a carbon tax is the best short-run option. There’s even a case, which a plan to discuss later, for leaving the tax in place when we come to introduce an emissions trading scheme, which is still the desirable outcome in the long run.
