Census crowdsource (repost)

John Quiggin8 Comments

In 2012, I crowdsourced an analysis of the census results, looking at the extent to which the increase in religion was driven by changes in stated affiliation from religious to non-religious, as opposed to the demographic replacement of older more religious cohorts by younger, less religous ones. A couple of wrinkles on this

* I didn’t mention immigration last time. It appears (unsurprisingly) that those born overseas are more likely to be religious, but less likely to be Christian, than the Australian born.

* As the ABS notes

The religious pattern of those under 18 is most similar to the 35-49 year olds, suggesting the form may be completed with their parents’ beliefs.

It seems likely that when they report for themselves, these young people will be more like the 19-34 age group. It’s hard to say whether we should call this an affiliation change or a cohort effect.

I’d like to ask again for a crowdsourced analysis. It may be useful to read the comments thread to my previous request.

Are the Nationals a political party?

John Quiggin15 Comments

I’ve made this point before, but I’m constantly reading articles about the rising share of “protest” votes going to “minor parties” in which the set of minor parties excludes the National Party. The reason is, of course, that the Nationals are a long-established party which, with a few state-level exceptions, operates in permanent coalition with the Liberals.

But, for all practical purposes, the same is true of the Greens. Roughly speaking, Labor and the Greens are in the position the Liberals and Nationals (and previously the Country Party) were for most of the 20th century. They fight three-cornered contests, often bitterly, and do a lot of agonising about preference swaps, coalitions and so on. But, when push comes to shove in terms of forming governments, they almost always line up together, whether in a coalition, with a formal agreement, or with informal support.

The most important difference between the two is that the Greens get more votes from a wider range of electorates. The difference that drives the spurious analysis of “protest parties” is that the coalition between Labor and the Greens is less formal and more fractious than that between the Liberals and Nationals.

If you count Labor and the Greens as a coalition, then the rise of protest parties in Australia appears primarily as a crackup of the political right. We’ve seen a profusion of rightwing protest parties, with only
the Xenophon group in the centre, and nothing much at all on the left. That differs from the situation in some other countries, where social democratic parties have embraced austerity and collapsed (Greece, Netherlands) or where the established leadership has been pushed aside (UK and possibly soon US also). I have some ideas about this, but I’ll have to write about them later.

But, coming back to the main point, a consistent analysis should treat both the Nationals and Greens as minor parties, or else neither of them.

Technology to the Rescue ?

John Quiggin38 Comments

There’s been a fair bit of buzz about an article in New York Magazine with an apocalyptic picture of climate change over the next century. I’ll for a more complete response later. But as it happens, I was already thinking about a much more optimistic post.

From the Climate Change Authority, of which I was a Member until recently, here’s a set of emissions trajectories consistent with a 67 per cent probability of limiting warming to 2 degrees.

There’s a pretty good case to be made that we are on the blue trajectory, and that, with decent political outcomes, we will be able to go below it and hold warming to the Paris aspirational target of 1.5 degrees. That would still have plenty of negative effects, for example on coral reefs, but it would not be an existential threat to humanity.

The points that are critical in the blue trajectory are a peak in emissions, right about now and a drop to zero net emissions by 2050. The first looks to have been achieved. As for the second, we are already seeing commitments to this goal from developed countries and jurisdictions, and there’s every reason to think it can be achieved at low cost.

As an economist, this is about the outcome I would have expected given a global commitment to an emissions trading scheme with a carbon price on a rising trajectory to $US100/tonne or so. In fact, we’ve seen nothing of the kind. There has been no real global co-ordination, and where carbon prices have been imposed, they have been low and limited in scope.

Instead, we’ve had a series of favorable technological surprises of which the most striking have been the plummeting cost of solar photovoltaics, and advances in battery technology allowing both low-cost electricity storage and affordable electric vehicles. There’s no reason to think these advances have run out, or that any of the remaining problem areas (air transport, cement manufacture and so on) will prove insuperable.

Not the way to bring down a government

John Quiggin31 Comments

According to the Sydney Morning Herald, Labor is launching court action with the objective of having a government minister disqualified from holding his seat in Parliament.

The opposition believes Assistant Health Minister David Gillespie may have an indirect financial interest in the Commonwealth – grounds for disqualification from office under section 44(v) of the constitution [which bans anyone who “has any direct or indirect pecuniary interest in any agreement with the Public Service of the Commonwealth”

As revealed by Fairfax Media in February, the Nationals MP owns a small suburban shopping complex at in Port Macquarie and one of the shops is an outlet of Australia Post – a government-owned corporation.

This is an absurd technicality, and I hope the High Court throws the case out. The Parliament is full of people on both sides whose main interest in holding office is in building up contacts for their future careers as lobbyists, bank sinecurists or both. If we can’t do something about this disgraceful situation, the idea of disqualifying someone for an obviously honest transaction with no potential for corruption adds insult to injury.

Expertise and punditry (updated)

John Quiggin19 Comments

I concluded my post “Against Epistocracy” with the question “Who gets to decide who is well-informed? And who gets to decide who gets to decide?”. This is, I think, a fatal flaw in any system proposing to replacing democracy with rule by a well-informed elite, or any kind of putative aristocracy. But even in a democratic system, we have to make decisions about who should decide things. In many cases, we would like to call on expert advice, and that brings us back to the question “who, if anybody, is an expert on a given topic”. I don’t have a complete answer, but I think it’s helpful to distinguish between experts and pundits or, better, between expertise and punditry.

Update: I just saw this review of The Death of Expertise: The Campaign Against Established Knowledge and Why it Matters by Tom Nichols which is obviously relevant. A crucial requirement for a successful defence of expertise is that we avoid defending authority based on mere punditry.
