Declining electricity consumption in Australia

July 25th, 2013 68 comments

I missed this when it came out a few weeks ago, but the Australian Energy Market Operation (AEMO) has released new forecasts of electricity demand to 2020. The forecasts represent a further reduction on the big cuts in estimated demand made between 2011 and 2012. In 2011, the medium forecast was for nearly 250 000 GWH by 2020, up from 200 000 in 2010. The latest medium forecast is 211 000 GWh for 2020, and the low forecast stays below 200 000 out to 2022-23. These forecasts would be even lower if it were not for three large export LNG projects in Queensland.

Even more striking is the forecast for residential and commercial consumption per persom. In much of the debate around energy issues, it is assumed that increases in living standards must go hand in hand with higher consumption of all forms of energy. But AEMO, assuming moderate rates of economic growth, is predicting that consumption per person will drop to 6000 KwH per year by 2020. In 2005, it was around 7200 KwH, so that’s a drop of more than 15 per cent. Over that time, income per person is likely to rise by around 30 per cent.

The AEMO measures don’t include rooftop solar, but they do include large-scale renewable energy (wind and grid-connected PV). Current policy calls for an additional 20 000 GWh of large-scale renewables by 2020, which would imply a significant reduction in energy-related CO2 emissions over the next decade.

Of course, a lot of this is the fortuitous result of high electricity prices, driven mainly by distribution costs. But it’s certainly an impressive demonstration that lower energy consumption does not mean lower living standards.

Why gold is different from Bitcoins

June 6th, 2013 35 comments

I have a new piece out in the National Interest, explaining why gold, unlike Bitcoins, will remain valuable for many years to come. In essence, gold has an intrinsic value derived from its industrial and decorative uses, and this value is enhanced by the demand for gold as a store of value, and by the belief (mistaken in my opinion, and certainly not an option I would favor) that gold-backed currencies may be restored.

By contrast, in my view, this piece by Robert Murphy misses the crucial distinction. Monetary demand can enhance intrinsic value, but it can’t make an intrinsically worthless asset valuable. He also fails to state the crucial point about fiat money. The “fiat” comes from the fact that a state can demand taxes can declare (“fiat”) that its money is acceptable in payment of those obligations. Hence, as long as the state can enforce its demands, its money has real value.

Some electricity links

April 30th, 2013 21 comments

The Australia Institute has a report out making the point that the growth in the administrative and marketing costs of electricity companies, following the reforms of the 1990s, has added more to electricity prices than has the carbon price.

Also, the Centre for Policy Development has a nice piece on solar PV coming out soon. Look for it.

Finally, here’s a piece I wrote for the The Economic and Labour Relations Review in 2001. Conclusion over the fold. I think it stacks up pretty well, certainly compared to the gushing praise for reform that was commonplace at the time.

The Bitcoin Bubble and a Bad Hypothesis

That’s the title of my latest piece at The National Interest. The blurb sums it up pretty well. Under the efficient-markets hypothesis, a worthless digital currency should have never gotten off the ground.

The good news

March 14th, 2013 58 comments

Discussions about reducing CO2 emissions often have a dismal tone, saying that we can’t reduce emissions without a drastic reduction in living standards. Sometimes the inference is that we should do nothing, other times that we should embrace drastically lower living standards (but probably won’t). Most people share this intuition to some extent, particularly as regards activities like driving, that seem central to a modern lifestyle. So, it’s striking to see what’s been happening to per capita gasoline consumption in the US


There’s a lot going on here: prices, fuel economy regulations, ethanol and general cultural shifts which have reduced distances driven. But the big point is that this drastic decline has happened with only modest policy measures, and without any obvious impact on living standards (US living standards haven’t done well in the 2000s, but for entirely different reasons). Looking ahead, Obama’s fuel economy regulations and sustained high prices should drive US gasoline consumption much lower.

Starting as I mean to go on (updated)

March 13th, 2013 125 comments

As I said in my last post, I’m giving as good as I get from now on, and today I seem to be getting plenty

Over at Catallaxy (Google it if you want), Sinclair Davidson is complaining about my Australian Laureate Fellowship (total budget, including lots of postdocs, PhD students etc, $2 million over 5 years) as an imposition on the taxpayer. Sinclair also receives a taxpayer funded salary of at least $150K. The standard assumption is that 30 per cent of a professorial salary is for research, the rest for teaching, administration, community service and so on. By contrast, I’m funded 100 per cent for research, my own and that of my students and collaborators. So, let’s see who is goofing off on the taxpayer dollar.

Here’s Sinclair: two journal articles\, and zero working papers in the last five years. On my arithmetic, allowing 30 per cent of salary for research, that’s a rate of over $100k per publication.
Here’s me 29 journal articles and 36 working papers in the same period. That’s about $30k per publication, without allowing for material produced by the postdocs and PhD students funded by my grant.

Those aren’t exhaustive lists of publications by any means, but I doubt that the relativities would change if we had a more complete list, including books, reports and so on. Adjusting for journal quality, as perceived by the profession, would make the difference even sharper.

Updated With their usual affinity for conspiracy theories, commenters here at and Catallaxy are suggesting that my current Fellowship is a favor from my Labor mates (readers here will be aware of my slavish devotion to our PM, which has, it seems, finally paid off). Of course, the great thing with conspiracy theories is that, the longer you look, the more conspirators you find. I’m sure the Catallaxians will be unsurprised to discover that this is, in fact, my fifth fellowship of this kind (the publication count above refers to my previous one), and that the previous four were all awarded by the Howard government.

Further update Sinclair Davidson has responded with a more complete list of his publications, including quite a few that appear neither on the IDEAS database (because it doesn’t include low-grade journals like Agenda and Policy nor on his personal webpage at RMIT. As I said above, it doesn’t change the relativities.

Yet further update Davidson has managed to convince the ever-gullible Andrew Bolt that pieces in Policy (not even ranked as a peer-reviewed journal by the ARC ranked C by the ARC), Agenda (ranked B) and a bunch of CIS/IPA publications constitute a stellar publication record. There’s nothing wrong with publishing in magazines like these (I do plenty of it), but it’s supposed to be a by-product of academic research, not a substitute for it. Bolt (innumerate, and out by two orders of magnitude on the impact of emissions policy), also repeats his claim that I’m the math-challenged one.

If there were still magazine stands, I’d be all over them today. Three pieces of mine have (coincidentally) come out on in the last day or so, in fairly disparate publications

* In Aeon (a new British “digital magazine of ideas and culture, publishing an original essay every weekday”), I have a followup to my first essay there, which argued the case for a Keynesian utopia, with a drastic reduction in market working hours. In my follow-up, I look at the environmental sustainability of the idea. The tagline for the essay “For the first time in history we could end poverty while protecting the global environment. But do we have the will? ”

* Continuing on the utopian theme, Jacobin magazine has published The Light on the Hill, a reply to Seth Ackerman’s piece on market socialism

* And, at The National Interest, a piece with the self-explanatory title, Will Banks Finally Be Brought to Heel?

While I’m plugging my own work, I thought some readers might be interested in this paper on financial liberalisation and asset bubbles, written in the leadup to the global financial crisis. There’s not much I would change now, and it’s still a pretty good summary of how I think about the financial bubble that created the crisis. The linked working paper version is from 2004, and it eventually appeared in the Journal of Economic Issues, the main journal of the institutionalists who carry on the tradition started by Veblen and Commons in early C20. Not surprisingly, given this obscure outlet, it hasn’t had a lot of attention.


January 14th, 2013 28 comments

My essay in (the new and exciting) Aeon magazine looking at Keynes’ suggestion that we could achieve decent living standards for all with an average of 15 hours a week of market work has had mostly favorable responses. But Kevin Vallier at the Bleeding Hearts Libertarian blog has now written a lengthy response and he doesn’t like it. Unfortunately, that’s about all I can say, since he throws a lot of adjectives (sectarian, morally impoverished and so on) at me without actually spelling out an objection.

Vallier’s response is in three parts. The first is a lengthy and fairly accurate, though hostile, summary of my general political position. He doesn’t offer a substantive criticism, but snipes about semantics Vallier objects, for example, to my “derisive” use of the term “market liberalism’ to describe “the sum total of pro-market economic thought that has had some influence over the last fifty years”. In fact, as I said in Zombie Economics, I picked the term precisely to avoid the pejorative connotations of the more commonly used “neoliberalism”[1]. What does Vallier propose here? I can’t spell out “the sum total of pro-market economic thought that has had some influence over the last fifty years” every time I want to refer to the ideas I’m criticising. In essence, I think he is upset that, by giving any name to the dominant ideas of recent decades, I am pointing out that they represent an ideology, with a history, rather than a set of timeless truths.

The second part of Vallier’s response is a summary of the main argument of my essay, but so brief that a reader who didn’t follow the link would have a very limited idea of what I was saying. The third part criticises me for advocating “coercion” against people who want to work hard and make money. Vallier doesn’t say what he means by this. The obvious incorrect inference, drawn by quite a few of his readers, is that I’m advocating statutory limits on hours of paid work[2]. However, he doesn’t seem to mean that. Rather, he seems to object to high income earners being required to pay taxes to support people who don’t work.

But this raises a puzzle. The only policy proposal I discuss in any detail is that for a guaranteed minimum income. But Vallier supports this – in fact, it’s pretty much the central distinction between Bleeding Heart Libertarians and the regular Republican+legal drugs kind.[3] So, is he inferring (correctly) that I’d propose a higher minimum than the BHLs? Or something else? I really don’t know.

More than a hacktivist

January 13th, 2013 23 comments

Many of you will have heard by now of the tragic death, by suicide, of Aaron Swartz, who was facing felony charges for an alleged attempt to distribute academic articles free of charge. It’s probably inevitable, as Henry Farrell says at Crooked Timber, that coverage of Aaron Swartz’ tragic death will focus narrowly on the story of Aaron as persecuted hacker. My main debt to him is almost entirely outside the tech sphere in which he made such big contributions. Early on in my blogging career, I came across the rightwing myth, that bans on DDT, inspired by Rachel Carson cost millions of lives. In fact, this was one of my first encounters with the rightwing parallel universe with which we are all familiar nowadays. At the time, most people hadn’t woken up to this, and the DDT myth was promulgated with great success. Tim Lambert and I spent years fighting the myth, ending up with this piece in Prospect. Along the way, we discovered the surprising fact that the myth was originally pushed by the tobacco industry, as a flank attack on public health bodies like WHO, which were trying to fight tobacco, and had (quite correctly) scaled back use of DDT, after early campaigns were defeated by the growth of resistance.

A crucial piece of the puzzle came from Aaron, who pointed out the central role of Roger Bate, an all-purpose anti-science activist based at the American Enterprise Institute (he’s largely moved on from DDT these days and is now fighting “counterfeit”, that is, unlicensed, versions of patented drugs). The DDT myth lives on in various corners of the blogosphere and still pops up from time to time in the mainstream media, but it’s now at least as easy to find refutations.

I honestly can’t imagine how someone could pack so much achievement into 26 years. Aaron’s loss is a tragedy for all of us, and the vindictive campaign against him by the Massachusetts prosecutors office (whose head, Carmen M. Ortiz, is regularly mentioned as being destined for higher office) was a crime.

Who are the criminals here?

January 12th, 2013 20 comments

I’m not a big fan of hoaxes, but the Whitehaven coal hoax (or rather, the reaction to it) has certainly provided plenty of teachable moments. Media stories are still calling it a $300 million hoax (while throwing stones at online reporting H/T Megan), and suggesting that Mums and Dads are big losers. Now we have some actual data, showing that clients of Morgan Stanley and Macquarie gained from the trades made during the hoax while those of Citigroup and UBS lost. [1]

Given the claim that hoaxes like this might destroy faith in the stock market, it’s worth looking at the track record of some of these banks. Looking just at the last few months, we have:

Morgan Stanley fined over Facebook IPO, 19/12/12
Citi fined $2 mln over Facebook IPO October 2012
Deutsche Bank, UBS Convicted by Milan Judge for Fraud Role

UBS in particular has a rap sheet so long that Bloomberg news recently published a call for it to be shut down

By comparison with these global titans, Macquarie Bank looks pretty good, despite being well-known as a sharp-elbowed practitioner of regulatory arbitrage
Regulator eyes millionaires factory

It’s now clear that this systematic criminality is part and parcel of modern financial markets, and that nothing can or will be done about it. After HSBC got a slap on the wrist for a long-term money laundering operation on behalf of drugdealers, dictators and terrorists, the US Department of Justice openly admitted that the big banks are not only too big to fail, but too important to be subject to the law. Modest fines are just a cost of doing business, exactly as they are for other businesses that routinely operate at the edge of, or outside the law.

Perhaps the clients of these firms are unaware of these facts. If so, this event might help to inform them. If not, they can scarcely complain about something as trivial as a hoax press release.

fn1. Apparently Morgan Stanley bought about $2.6 million of shares, which would imply a profit of around $500k, a significant sum, but several orders of magnitude below the $300 million quoted

Krugman on 2013 vs 1958 macro

January 10th, 2013 44 comments

At the recent American Economic Association meeting in San Diego, Brad DeLong chaired a panel on ” Stimulus or Stymied?: The Macroeconomics of Recessions“, and has posted a transcript. Paul Krugman was there and picked up my claim that macroeconomics has, on balance, gone backwards since 1958. I’ve extracted his section here. Lots of useful stuff, but I’d stress this:

the whole basis on which we constructed monetary policy during the Great Moderation, which is that stabilizing inflation and stabilizing output are the same thing, is all wrong: you can have a sustained period of low but not negative inflation consistent with an economy operating far below its potential productive capacity. That is what I believe is happening now. If so, we are failing dismally in responding to this economic crisis. This is in contrast to what some central bankers are saying—that we have done well because inflation has stayed relatively stable.

To push this a bit further, I’d argue that there will be no real recovery as long as central banks continue to treat the inflation-targeting polices of the (spurious) Great Moderation as the pre-crisis normal to which we should strive to return

How effective is fiscal policy: Guest post from Roger Farmer (crosspost at CT)

January 8th, 2013 14 comments

Roger Farmer, professor of economics at UCLA, has sent a response to my post on the fiscal multiplier, which is over the fold. I’ll make some substantive points in comments, but I’d like to start by saying that this is a good example of a discussion to which blogs are ideally suited. Contributions from people like Roger who have something important to say, but not the time or inclination for a regular blog, make it even better.

The state of macroeconomics: it all went wrong in 1958

January 5th, 2013 35 comments

Much of the recent discussion in the “state of macroeconomics” has concerned the question

* Is macroeconomics making progress?
* If not, when did it stop?

I’m not going to survey the whole debate, but I will point to a good contribution from Robert Gordon (linked by JW Mason in comments to a previous post). Gordon argues that 1978-era New Keynesian macro is better than the DSGE approach dominant today. That implies 30 years of retrogression.

My own view is even more pessimistic. On balance, I think macroeconomics has gone backwards since the discovery of the Phillips curve in 1958 [1][2]. The subsequent 50+ years has been a history of mistakes, overcorrection and partial countercorrections. To be sure, quite a lot has been learned, but as far as policy is concerned, even more has been forgotten. The result is that lots of economists are now making claims that would have been considered absurd, even by pre-Keynesian economists like Irving Fisher.

The big issues in macroeconomics: the fiscal multiplier

January 4th, 2013 39 comments

The biggest theoretical issue in macroeconomics is “what causes unemployment”. As discussed in the last post, the classical answer, that unemployment is caused by problems in labor markets, is obviously wrong as an explanation of the simultaneous emergence of sustained high unemployment in many different countries. Unemployment is a macroeconomic problem.

The central macroeconomic policy issue, then, is “what, if anything, can macroeconomic policy do to move the economy back to full employment”. If you accept that, under current conditions of zero interest rates, there’s not much positive that can be done with monetary policy[1], and you stay within the bounds of mainstream policy debate, this question can be restated as “how effective is expansionary fiscal policy” or, in Keynesian terms, “how large is the fiscal multiplier in a depression”.

The big issues in macroeconomics: unemployment

January 3rd, 2013 30 comments

Following up my previous post, I want to look at the main areas of disagreement in macroeconomics. As well as trying to cover the issues, I’ll be making the point that the (mainstream) economics profession is so radically divided on these issues that any idea of a consensus, or even of disagreement within a broadly accepted analytical framework, is nonsense. The fact that, despite these radical disagreements, many specialists in macroeconomics don’t see a problem is, itself, part of the problem.

I’ll start with the central issue of macroeconomics, unemployment. It’s the central issue because macroeconomics begins with Keynes’ claim that a market economy can stay for substantial periods, in a situation of high unemployment and excess supply in all markets. If this claim is false, as argued by both classical and New Classical economists, then there is no need for a separate field of macroeconomics – everything can and should be derived from (standard neoclassical) microeconomics.

Rachel Nolan on the case for privatisation

December 2nd, 2012 60 comments

During the long debate over the Bligh government’s sale of public assets, I was frustrated by the government’s refusal to mount a serious case in favour of the sales. The official argument, that the money gained from the sale of income-earning assets could be used to finance the building of schools and hospitals was such obvious nonsense that even strong advocates of privatisation like Henry Ergas were willing to sign a letter I organized pointing this out and calling for a proper debate. Now finally, former Transport Minister Rachel Nolan has given us some idea of what the government was really thinking.

Nolan has a piece in Quarterly Essay (paywalled, but there is a summary from Laura Tingle here), in which she laments that Australians “have little philosophical grasp of the (rightful) diminution of governmental power which deregulation has brought” . She retails some anecdotes of being besieged by “rent-seekers” wanting her to direct Queensland Rail in various ways[1], and complains about constituents wanting her to fix various things outside her control.

The Great Oil Fallacy

November 27th, 2012 117 comments

That’s the headline for a piece I published in The National Interest last week. Opening paras

Among the unchallenged verities of U.S. politics, the most universally accepted is that of the crucial strategic and economic significance of oil, and particularly Middle Eastern oil. On the right, the need for oil is seen as justifying an expanded and assertive military posture, as well as the removal of restrictions on domestic drilling. On the left, U.S. foreign-policy is seen through the prism of “War for Oil,” while the specter of Peak Oil threatens to bring the whole system down in ruins.
The prosaic reality is that oil is a commodity much like any other. As with every major commodity, oil markets have some special features that affect supply, demand and prices. But oil is no more special or critical than coal, gas or metals—let alone food.

This piece expands on my earlier argument that the US has no national interest at stake in the Middle East, just a set of mutually inconsistent sectional interests and policy agendas. I don’t talk about climate change explicitly, but we’ll never have a sensible debate about climate change until oil is demystified.

In which I agree with Megan McArdle (crosspost from Crooked Timber)

November 23rd, 2012 20 comments

For quite a while, I’ve been arguing that the simultaneous occurrence of sustained depression in most developed countries provides fairly conclusive evidence that both new classical macroeconomics and standard versions of real business cycle theory cannot explain actual macroeconomic outcomes. That argument is directed both against US-based economists like Casey Mulligan and Narayana Kocherlakota, who are trying to explain the US experience in terms of problems specific to the US labor market[1] and to European advocates of austerity who blame the crisis in peripheral European countries on (mostly falsely) alleged government profligacy in those countries.

An immediate implication, drawn out here by Paul Krugman, is that the success or otherwise of the limited stimulus undertaken by the Obama Administration should be assessed by comparison to the performance of other countries, most of which undertook less stimulus, returned to austerity faster, and have experienced correspondingly weaker growth (as some Oz tweeps are pointing out, he might have mentioned Australia, which undertook a big stimulus and avoided recession altogether).

But, as Megan McArdle snarks here, there’s an implication more appealing to Republicans. If Obama can’t be blamed for a global recession, neither can Bush. Although McArdle’s argument isn’t watertight (the US is big enough that US actions have a big effect on the world as a whole), the conclusion is broadly correct. There’s plenty of blame to go around for the Global Financial Crisis and the subsequent depression, and the Bush Administration deserves only a small share. Bush’s main contribution was to introduce unfunded tax cuts at a time when the budget should have been in surplus, thereby reducing the fiscal space available for stimulus when the crisis came. But, given the weakness of the stimulus and the ferocity of the political response, it’s not clear that was a binding constraint in any case.

The primary culprit is market liberal economics, which may be considered both as a set of ideas with its own internal logic and as an expression of the class interests of those who benefit from the finance-dominated form of capitalism that produced the crisis and has prevented any recovery. My book Zombie Economics is a critique of market liberalism considered as an economic theory, showing how market liberalism produced the crisis. Colin Crouch’s Strange Non-Death of NeoLiberalism gives more of the class interpretation, explainign why these discredited ideas remain dominant.

Mulligan talks his book

November 8th, 2012 24 comments

Before engaging in another round with Casey Mulligan, I’d like to say that, while I find most of his arguments implausible, I don’t think he’s silly for making them. Given the position he’s trying to defend, these are the best arguments available. And that position is widely shared, not only by economists much more famous than Mulligan but by lots of governments and policymakers. Most mainstream opponents of Keynesianism are committed, one way or another, to the view that persistent high unemployment must be caused by problems in labour markets. But it’s much easier to talk in vague general terms about rigidities and structural imbalances than to present an operational explanation for the sustained high US unemployment of the last four years. Mulligan at least makes the attempt, which is more than most of the New Classical/Chicago/Real Business Cycle school have done, and necessary if there is to be any progress in the debate.

Replying to my criticism of his NY Times column, Mulligan suggests that I should have read his book. Perhaps so, but the column is presented as a critique of Krugman’s book, not a plug for Mulligan’s, and I responded in that light. His latest post mentions a couple of points where he draws on the book, but for the moment I’m going to continue to rely on data published elsewhere.

Mulligan responds to my points in reverse order, which makes sense, because his response to my central point is by far his weakest. The big difficulty for an explanation of post-2008 unemployment based on US welfare policies (unemployment insurance and food stamps) is that many other countries with radically different labor markets and policy responses experienced a big and sustained increase in unemployment at exactly the same time, following the global financial crisis of late 2008. In particular, lots of countries introduced austerity policies involving sharp cuts in the kinds of benefits Mulligan is criticising. Mulligan’s response to this evidence is handwaving. First he says that I haven’t calculated the implied changes in marginal tax rates, although its pretty obvious that most of them will be reductions. Then he resorts to US exceptionalism, saying

Finally, if marginal tax rates were found to be constant in Estonia (the only specific country that Professor Quiggin points to), does that mean that marginal tax rates do not matter in the U.S.? Please let me know so I can notify American economists that Estonia is our ideal laboratory, and notify policymakers that they can safety hike marginal tax rates to 100 percent without noticeable consequences.

That’s pretty startling for someone representing a school of thought which usually treats economic laws as having the same universal applicability as those of physics.

To try and make sense of an argument like Mulligan’s you’d have to start with the financial crisis as a global shock, then claim that, if only governments had sat on their hands, recovery would have been rapid. Instead, the argument would run, governments acted to alleviate the lot of the unemployed and thereby made things worse. That would be a coherent explanation for simultaneous and sustained increases in unemployment – the only difficulty is that it’s directly contrary to the facts.

It’s worth making the distinction here between changes and levels. Lots of European countries have high marginal tax rates and generous unemployment benefits, relative to the US. But, in many of the worst hit countries, benefits have been greatly reduced. By contrast in the US, benefits are very low but at least some have been increased. If, like Mulligan, you want to argue in terms of changes, then Europe should have seen reductions in unemployment (which was previously higher than the US). In reality, there is very little correlation between labor market policies and changes in unemployment. What has mattered has been exposure to the initial financial sector shock and/or subsequent austerity policies, exactly as Keynesian analysis would predict.

Food stamps cause global depression?

November 2nd, 2012 60 comments

Chicago is about as close to the American heartland as you can get and still be in a major city (the infamous Heartland Institute is located there, for example), but even so, I’d expect a professor at the University of Chicago to be aware that the USA is not the only country in the world. That’s not true, apparently, of Casey Mulligan, who claims that the continued weakness of employment in the US is due to policies introduced in 2008 and 2009, which ” greatly enhanced the help given to the poor and unemployed — from expansion of food-stamp eligibility to enlargement of food-stamp benefits to payment of unemployment bonuses — sharply eroding (and, in some cases, fully eliminating) the incentives for workers to seek and retain jobs, and for employers to create jobs or avoid layoffs.”

Mulligan’s claims about US policy are dubious at best (see over fold), but there’s a much more critical problem with his argument. If US unemployment is caused, not by a demand shock but by the mistaken policies of the Obama Administration, why did unemployment move in the same way, and at the same time, in many different countries? Did Iceland expand its food stamp program? Does Estonia pay unemployment bonuses? Sadly, no. And while many countries adopted Keynesian policies in the immediate aftermath of the Wall Street meltdown, others did not, and most have now switched to the disastrous policy of austerity. An even clearer demonstration is given by the Great Depression, where nearly all governments pursued austerity policies after 1929 (Mark Blyth’s soon-to-appear Austerity: The History of a Dangerous Idea tells the story)>

This isn’t just a problem for Mulligan. The simultaneous occurrence of a sustained increase in unemployment in many countries, with different institutions and policies undermines any explanation of unemployment that works at the national level. That includes all forms of New Classical Economics, in which unemployment arises from labor market “distortions”, as well as Real Business Cycle theories (except if you stretch the idea of a technology shock to the point where “technology” effectively means “aggregate demand”).

Opportunity knocks

October 12th, 2012 18 comments

I’m very interested in ways of increasing leisure, so when I saw mention of The Four-Hour Workweek, I naturally rushed to check it out. It turns out to be about “Outsourcing your Life” by hiring a fleet of remote executive assistants from India, to handle your email, pay your bills, run interference between you and your wife (really! ) and generally to replicate the archetypal “office wife” secretary, right down to the 1950s gender stereotypes.

That wasn’t what I had in mind at all, but just after seeing the link, I got an email asking about a presentation I gave last year, and which I had totally forgotten. It only took me a few seconds to find it (one reason I don’t want a remote EA), and to recall that it’s an improved version of this old blog post which reads as if it was written just before I joined Crooked Timber. But I haven’t got around to turning into an article and probably never will.

September 5th, 2012 29 comments

… unless you expect to be in for one term at most. Having announced that Queensland is on the verge of defaulting on its public debt, as in Greece and Spain, and sacked thousands of public servants, Campbell Newman is now proposing to build a brand-new office tower in the Brisbane CBD, to be financed by the sale of up to 20 other buildings including heritage assets. Apart from the economics, this is a direct breach of the LNP promise, crucial to its election victory, not to undertake asset sales before the next election. The project is being sold as “self-financing”, but this claim appears to rely almost entirely on rosy scenarios and magical ponies.

Proposals like this make sense of one of the more puzzling features of the Costello Commission of Audit, namely its insistence that the capital expenditure projections of the previous government were unsustainably low. The projections appeared reasonable on the assumption that, in straitened times, there wouldn’t be any major new initiatives, as opposed to maintaining and modestly extending existing infrastructure. But, obviously Costello understood that Campbell Newman (like Anna Bligh) was not the kind of Premier who could forgo lots of TV appearances in a hard hat. In this context, it’s worth re-examining his record as Lord Mayor which involved buying short-term popularity at the expense of long term debt – exactly the opposite of what he now says Queensland needs

Prog rock epiphany

August 26th, 2012 28 comments

Over at Slate, Dave Weigel has a series on progressive rock for which he admits a fondness, while quoting a description of it as the “single most deplored genre of postwar pop music.”. Thanks to the playing of Mike Oldfield’s Tubular Bells at the Olympics opening ceremony, there’s even talk of a revival. As it happens, this album played a significant role in my life – in fact, it was something of an epiphany, which changed my views on all kinds of things, though not in the same way as for Weigel.

Singularity review repost

August 22nd, 2012 40 comments

The discussion of my repost on the silliness of generational tropes produced a surprising amount of agreement on the main point, then a lot of disagreement on the question of technological progress. So, I thought I’d continue reprising my greatest hits with this review of Kurzweil’s singularity post, which I put up in draft from at Crooked Timber and my own blog, producing lots of interesting discussion.  Again, seven years old, but I don’t see the need to change much – YMMV

How to solve the solar storage problem

August 22nd, 2012 130 comments

Australians installed more domestic rooftop solar PV in 2011 than in any other country in the world. Despite sharp cuts in subsidies, that seems likely to continue, and raises the question of how this will effect patterns of electricity demand and in particular the capacity of the electricity system to meet peak demand. I just ran across an interesting infographic prepared by a consulting group called Exigency management which puts the question into sharper focus . Under current conditions, demand peaks around noon, remains high through the afternoon, then has another peak in the early evening, as people come home and turn on airconditioning or heating. Widespread takeup of home solar PV will increase supply at the noon peak and even more in the afternoon, but drop off as evening approaches. The result, in the absence of any other changes, will be a system with a demand trough in mid-afternoon followed by a much sharper evening peak.

What can be done about this? The first point to observe is that the demand projection is under current pricing rules. Any sensible system, faced with a demand pattern like this would set peak prices to cover the actual demand peak, not the one that prevailed under a 20th century coal-based system. But, price incentives alone aren’t satisfactory in the absence of some way of storing energy. There’s been lots of discussion of more-or-less exotic solutions, but there’s a much simpler answer.
