The MFP illusion

John Quiggin23 Comments

Expanding on a post a little while ago, I have a piece in Inside Story arguing that multi-factor productivity, the Holy Grail of microeconomic reform for the last few decades, is a residual that is and should be equal to zero.

From getting the idea to publishing it took me a few weeks. That’s a huge contrast from last century when the best I could have hoped for is an article in a low-prestige journal, taking a year or more and reaching an audience of, at most, a few hundred.

That’s great for me, as I’m more interested in reaching a large intelligent public than in impressing my fellow economists (I have to do that to keep my job, of course, but it’s not my top priority). By contrast, the general direction of the profession has been towards fewer and fewer articles in an ever-narrower range of prestigious journals.

The end of fossil fuels: some data and quick calculations

John Quiggin44 Comments

The International Energy Agency recently released data showing that world coal production fell sharply in 2016, mainly because of big cuts in China. Looking at the graph, it appears that the peak in production was around 2013. The price of coal has experienced a “dead cat bounce” over the last year or so, essentially because China has been closing coal mines faster than it’s been closing or cancelling coal-fired power stations, but the picture tells the story for the future.

Global coal production (source IEA)

Until relatively recently, the decline of coal was the result of competition with gas, while new renewables weren’t even enough to cover the growth in demand. But a quick calculation shows that renewables will soon be taking out a bigger bite. Global electricity generation is currently about 20000 terawatt-hours (TWh) a year, growing at around 1.5 per cent, or 300TWh a year. Installations of solar PV and wind (I haven’t checked on hydro and other renewables) for 2017 look set to come in around 150 gigawatts (GW). Assuming 2000 hours of operation per year, that’s just enough to offset demand growth. So, any future growth in renewables must come directly at the expense of existing fossil fuel generation which in practice will almost always mean coal.

Turning to transport, regular commenter James Wimberley has an analysis of the prospects for peak gasoline (petrol) used in internal combustion engines. Summarising drastically, his best estimate for peak gasoline is 2032. Decarbonization requires an end to petrol-driven vehicle sales by around 2035. On this front, the good news is that quite a few countries, including the UK, France and India are pushing for an end by 2030.

Of course, all of this assumes that the attempts of Trump and Turnbull (along with likeminded culture warriors in Turkey, Poland and elsewhere) to bail out the dying coal industry come to nothing and also that Trump doesn’t manage to destroy the planet through nuclear war.

Lamest. PM. Ever.

So, we’ve wasted $100 million on a postal survey that won’t decide anything. It’s already evident that, even with a thumping majority for Yes, the bigots on the LNP backbench will fight all the way to protect the right to be a bigot. They are, in my view, playing a dangerous game here. The existing law gives lots of special privileges to religious organizations that are justified only on the basis that we all need to get along tolerantly. If that rationale ceases to apply, all those privileges are open to question.

Meanwhile, all the fine words about letting the people decide have gone out the window when it comes to indigenous recognition. Even though Abbott has gone along with Turnbull on the decision, I think, if he were still PM. he might have done better on this issue.

In any case, this confirms me in the view that Turnbull is the weakest Prime Minister in living memory. I thought that Billy McMahon was a competitor for the title until I discovered that he took the decision to kill off Australia’s foray into nuclear power (they’d actually excavated the site at Jervis Bay) over the opposition of the redoubtable Sir Phillip Baxter who saw the project as a step towards an atomic weapons capability. The cancellation of this project was a bigger achievement than Turnbull can claim in his 20-odd years in public life, encompassing the Republic referendum, the Murray-Darling fiasco, the downgrade of the NBN and his two years as Prime Minister.

Nuclear starts stop

A steady stream of negative evidence hasn’t shaken the faith of believers in nuclear energy. Many of them are under the impression that the failure of nuclear energy is specific to the developed world, where some combination of environmentalism and NIMBYism prevents the adoption of an obviously sensible solution. It is widely imagined that China, India and other countries are forging ahead. This idea was plausible until fairly recently, but the latest evidence suggests that nuclear power is in terminal decline. Globally, only four nuclear plants commenced construction between 1 January 2016 and 30 JUne 2017. China hasn’t started any new plants this year and is sure to miss the 58GW target set for 2020.

The problem, simply, is that while China’s problems with delays and cost overruns have been less severe than those in the developed world, the same patterns are evident. New nuclear plants simply can’t compete with renewables.

I don’t expect that this will have the slightest impact on the Australian and US right, who have long since ceased to regard evidence as relevant to anything. But, for anyone who is still open to evidence, this debate ought to be over.

Judaeo-Christian

John Quiggin36 Comments

My son Daniel pointed out to me a feature of Trump’s speech to the laughably named Values Voters summit which seems to have slipped by most observers. As summarized by Colbert King in the Washington Post

Telling a revved-up Values Voter audience that he is “stopping cold the attacks on Judeo-Christian values,” Trump suggested to the crowd, which already thinks a “war on Christianity” is being waged, that invoking “Merry Christmas” is a way of fighting back.

But “Happy Holidays” is exactly an expression of Judaeo-Christian values, coined to embrace the Jewish Hanukkah as well as Christmas. In this context, King’s suggestion that “Happy Holidays” is secular misses the point. The majority of secular Americans celebrate Christmas (happily mixing Santa Claus, carols, and consumerism). They say “Happy Holidays” as a nod to religious diversity among believers, not because they feel excluded from Christmas.

Insistence on “Merry Christmas”, by contrast, is a repudiation of the claim implicit in “Judaeo-Christian”, namely, that Jews and Christians have essentially the same beliefs and worship the same god, and that the differences between the two are ultimately less important than the commonalities. On any interpretation of Christianity in which all who reject Christ (including, I imagine, most of us here at CT) are damned, “Judaeo-Christian” is a much more pernicious version of political correctness than “Happy Holidays”.

I haven’t got to a proper analysis of this, so I’ll turn it over to commenters.

Pumped hydro

John Quiggin34 Comments

In my Conversation article on the Turnbull government’s plan to keep coal-fired electricity alive, I said that most of the opportunities for hydro-electric power had already been exploited. I was thinking of primary power generation, and in this respect, I maintain my view. However, I neglected the option of pumped storage, where water is pumped uphill when excess electricity is available, then run downhill through turbines to (re)generate the electricity when it is most needed.

My old university friend, Andrew Blakers, now with the Research School of Engineering at ANU emailed me to point out this study, looking at the large number of sites potentially available in Australia, more than enough to backup all the renewable energy we will be generating in the foreseeable future.

This isn’t just a theoretical proposition. The Kidston hydro storage project in the advanced stages of planning, will offer 2000MwH of storage combined with a co-located 270MW solar PV project. The same report mentions some big wind + storage projects.

Still, if Labor is silly enough to endorse Turnbull’s NEG idea, it’s hard to see any more progress being made.
