Who should be licensed to use the road?

John Quiggin101 Comments

I’ve seen a number of interesting things in relation to road safety lately, some of which have caused me to revise my thoughts.

First, there’s the question of retesting for older drivers. This seemed self-evidently desirable to me, based on data showing very high fatality rates per km driven and that in most collision involving older (75+) drivers they are at fault. However, a Twitter discussion (must work out how to do Storify!) following this Background Briefing showed that things aren’t nearly so clear-cut. The fatality evidence isn’t really helpful, since it just reflects the fact that an accident is more likely to be fatal to an older person than to a younger one. The differential hazard is far greater for falls, which suggests that forcing older people out of cars may not be beneficial. And overall, the evidence on the benefits of testing appears to be mixed at best (the Monash expert quoted in BB overstates the case a bit, in my view).

More directly relevant to me (at least for the next decade or two) there are some suggestions regarding cyclist: a one-meter clearance requirement for cars , relaxation of abolition of helmet laws and requirements for licensing, rego and third-party insurance. The first is obviously sensible, the big issue being enforcement. On the third, I agree in principle with licensing and TPI, the main problem being what to do about children. Registration seems undesirable until we have a proper system of road pricing.

On helmets, I’m genuinely ambivalent, particularly after witnessing a head impact accident this morning (no injury, thanks to helmet). I would always use a helmet, but I’m not happy about the claim that Australia should have different helmet laws than Europe because our roads are more dangerous, and our drivers more aggressive. Granted that this is true we need to change these conditions. The obvious first step would be to reduce the current 60/50 speed limits for suburban streets and subarterial roads respectively to 50/40. This would greatly benefit road users (including both cyclists and older drivers) who can’t or don’t want to travel at or near existing speed limits. The welfare cost of slightly lower limits would, in my view, be trivial. I have zero sympathy for those (echoing smokers and polluters of all kinds) who want their convenience to justify imposing risks on others.

The other point though relates to those aggressive drivers. Whereas the evidence on older drivers is weak, there is ample evidence that aggressive driving, manifested particularly in traffic violations, is associated with higher crash risk, as is at-fault involvement in a previous crash. The current points system is absurdly lenient in this respect. The 12 point allowance lets drivers be convicted over a serious offence (running stop lights, speeding in a school zone etc) every year without any restriction on driving, and the suspension period for violators is only few months. I’d suggest a lifetime allowance of 24 points, with permanent restrictions thereafter, as well as reducing the three year allowance to 8 points, and increasing suspension periods.

The restrictive treatment of drivers at the older and younger ends of the age spectrum contrasts sharply with the treatment of a drivers license as a natural right for the 25-75 group, to be withdrawn only in extreme cases. In my view, aggressive drivers should be taken off the road to make them safer for the rest of us, including non-motorists and those whose reflexes aren’t sharp enough to cope with the high-speed high-risk driving of others.

Peak euphemism? #Ozfail

John Quiggin79 Comments

We’ve been used to imagining the global supply of euphemisms as limitless, but if Dennis Shanahan keeps at it, the world will be running short by the time the Abbott government leaves office. In a single column (Google it) he manages to refer to “accusations of broken promises”, “the shift on the Gonski education promise”, “the repudiation of Labor’s Gonski education promises”, “The management of the Gonski “unity ticket” on education funding”, ” accusations of broken promises” (again), “The readjustment of expectations on Gonski” “the painful Gonski process” and “a cusp of credibility”. Given his leader’s penchant for three word slogans, perhaps a three-letter word starting with “L” might be what Shanahan is reaching for here.

Peak aluminium?

John Quiggin76 Comments

The announcement that Rio Tinto is to close its alumina refinery at Gove struck me for a number of reasons, starting with the fact that members of my family are affected by it. First up it’s worth noticing what’s mentioned (the high dollar and low aluminium price, which flows through to bauxite and alumina) and what isn’t (the carbon tax and legislation for its removal). Having claimed that he was going to save industries like alumina and aluminium smelting from the carbon tax “wrecking ball”, Abbott is now shown up, once again, as a fraud[1].

In the short run, the obvious policy implication is that the RBA needs to be firmer in pushing the dollar down. It was, I think, a mistake to hose down talk of direct intervention, as was done recently. Given our declining terms of trade, we should be closer to $US0.80 than $US0.90 now, and heading down further.

The bigger question of interest, though, is the future of aluminium. The big story of the past 10-20 years has been the massive growth of production in China, driven by cheap coal-fired power and lots of subsidies. That’s driven prices down to historically low levels (inflation-adjusted, probably record lows). Production in Australia is now clearly uneconomic, but even the Chinese are losing billions.

Declining prices have driven steady growth in demand for aluminium. Since the supply of recycled aluminium is dependent on past production, there has been a multiplied effect on demand for primary aluminium, which is the big driver of greenhouse gas production in this industry.

The general assumption (as with most trends) has been that these trends will continue indefinitely. But it’s clear that prices have to rise just to cover costs, and will rise further as China starts to price the local and carbon costs of coal-fired electricity. Moreover, in technological terms, aluminium is definitely a 20th century commodity. Its inherent properties of lightness and strength gave it great advantages, but it is now being displaced in advanced uses by carbon fibre and in some basic uses by lightweight steels.

So, it seems to me quite plausible that aluminium demand could stabilise over the next decade or two, with the result that most demand can be met by recycling rather than energy-intensive production of primary aluminium from bauxite (via alumina).

Note: I topic-banned regular commenter Hermit from talking about aluminium smelters, as it become an idee fixe. The ban is lifted for this post.

fn1. Has any new PM ever been shown up so comprehensively in such a short time? Not in my memory, which goes back to Harold Holt, and includes some shockers.

Hockey or Turnbull

John Quiggin38 Comments

The election that brought Abbott and the LNP to power is so three months ago, and the Christmas plotting season is nearly upon us, so it’s time for some good old-fashioned leadership speculation, with the Libs as the target this time around. According to Laura Tingle, most of the interest in the business community is in Turnbull. I think that would be a bridge too far for the Liberals, having dumped him once. So, my money would be on Hockey as the replacement if Abbott keeps messing things up as he has done almost continuously since taking office. While the accuracy of my political judgements is pretty variable, this one from a year ago is looking fairly good.

Hockey has indeed backed off the surplus, showing more good sense than Abbott. I’m nearly alone in this view, but I think he is under-rated. Not a towering intellect, but still among the stronger performers on the LNP front bench.

Crikey goes Godwin on tiny uninhabited islands

John Quiggin18 Comments

The usually sensible Crikey team has gone off the deep end (in an editorial sent out as email, can’t find it on their site) on the Australian government’s response to the recent dispute between China and, among others, the US over a group of “tiny uninhabited islands” (even the name is disputed). The longstanding policy of Australian governments, very sensibly, has been to avoid getting between the US and China on issues like this, of which there are a huge number, involving many parties and incomprehensible claims. Crikey not only endorses Julie Bishop’s abandonment of this policy, but uses the loaded term “appeasement” to describe opponents. So, a refusal to get involved in a game of posturing and sabre-rattling that has gone on, in one form or another, since 1949, is equivalent to selling out the Czechs to Hitler.

Crikey draws a comparison with Kevin Rudd’s willingness to take the Chinese leadership to task over human rights abuses, a willingness criticised by Bishop at the time. To see how absurd this is, you need only ask whether Chinese dissidents, who mostly endorsed Rudd’s speech (some thought it did not go far enough) are going to welcome our support for the anti-China position in this territorial dispute. The answer is obvious: for the most part, Chinese democrats fully support the government position on these issues.

The idea that, having just ignored human rights issues in Sri Lanka, the Abbott government has suddenly developed a concern with these issues in China is equally absurd.

Grattan on Growth

John Quiggin52 Comments

I’ve been asked a few times about the Grattan Institute’s new report Balancing budgets: tough choices we need. It’s a substantial piece of work, and isn’t driven by a partisan agenda or special interest lobbying. On the other hand, I disagree strongly with the implicit criterion for policy design. This is nowhere spelt out, but the analysis is clearly driven by the following rule: seek policies that maximize GDP growth, subject to the constraint that the poorest (bottom 20 per cent of) households should not be made worse off.

This is most evident in the recommendation to remove the GST exemption for fresh food and use some of the proceeds to compensate the poorest 20 per cent of households. Let’s compare this with the alternative of raising income tax rates for high income earners (say, the top 20 per cent). By design, neither proposal has much net effect on the poorest 20 per cent. But the food tax falls mostly on the middle 60 per cent of households, since the top 20 per cent don’t spend much more on fresh food than the middle income group. It’s true that the cost of raising money through income tax is higher (Grattan uses an estimated cost of 25 per cent of the gross revenue) than for a food tax (5-10 per cent). But let’s spell this out a bit. Suppose you need to raise $500 in net revenue (roughly speaking what you’d get from the food tax for a household spending $100 a week). Would it be better to impose the tax on Gina Rinehart (in which case, taking account of the economic costs of collecting the tax, you’d have to raise an extra $100 or so compared to the food tax) or on one of her employees. If you regard Rinehart as an extreme example, take the choice between taxing a university professor (definitely in the top 20 per cent) or a campus worker such as a gardener or cleaner (not in the top 20 per cent, but normally not in the bottom 20 either, since this group consists almost entirely of people on pensions and benefits).

The fact is that Howard’s tax cuts, mostly carried on by Labor, used the temporary proceeds of the mining boom to permanently increase the after-tax income of the top 20 per cent. That’s the biggest single cause of the budget problems identified by the Grattan Institute, and the first thing that needs to change if we are to fix those problems.

How word targets help creative procrastination

John Quiggin21 Comments

I think I’ve written before about creative procrastination, but I can’t immediately find it, so I’ll restate my idea here. Whenever you have an urgent deadline, the desire to procrastinate becomes irresistible. Rather than trying to resist it, the optimal response is to succumb, but to have a list of necessary but non-urgent tasks at hand (as I’ve argued before, there’s no need to prioritise non-urgent tasks. Just divide them into those you are going to do, and those you aren’t, then do them in whatever order suits). Now, the guilt induced by the deadline should stop you goofing off on FB, killing boars or whatever, so the desire to procrastinate will force you to tackle the jobs on your list. Then, as the deadline approaches you will finish the job. This works even better if (as is usually the case) an extension of the deadline is possible, but you can conceal this knowledge from yourself until the last possible moment. That way, you get a second round of creative procrastination, plus you have enough time to do the main job properly.

That’s all revision. My new idea for today links this to my long-standing advocacy of word targets. I try to write 500 to 750 words of new material every day. 500 words a day might not sound much, but if you can manage it 5 days a week for 40 weeks a year, you’ve got 100 000 words, which is enough for half a dozen journal articles and a small book. So, that’s my target. If I haven’t written enough one day, I try to catch it up the next day and so on.

And here’s the link. If you’re involved in a big project like a book, or a PhD, there aren’t really any deadlines. But, if you make a rule of being caught up on your word target at the end of the week, you create an automatic deadline for yourself. While doing your best to avoid dealing with this deadline, you create an automatic opportunity for creative procrastination, during which you can deal with admin tasks, write blog posts, sort out your reference system and so on.

Obviously, everyone is different. But this has certainly worked for me and, as a by-product, for you, my readers (at least, those of you who don’t just come here to get annoyed at whatever lefty nonsense I’m banging on with today). In the past 10 years, WordPress tells me, I’ve written over 5000 blog posts, while still keeping up the supply of books and journal articles for which I earn my living, and, I hope, managing to keep plenty of time for family and friends.
