Do climate sceptics exist?

by John Quiggin on July 25, 2016

June 2016 was the hottest month globally since records began in 1880, and marks the fourteenth record month in a row. For the great majority of people who’ve been following scientific findings on climate, there’s no great surprise there. There is very strong evidence both for the existence of a warming trend due mainly to emissions of carbon dioxide, and for the occurrence of a peak in the El Nino/Southern Oscillation index. Combine the two, and a record high temperature is very likely.

But suppose you were a strongly sceptical person, who required more evidence than others to accept a scientific hypothesis, such as that of of anthropogenic climate change. Presumably, you would treat the evidence of the last couple of years as supporting the hypothesis. Perhaps this supporting evidence would be sufficient that you would regard the hypothesis as confirmed beyond reasonable doubt, perhaps not, but either way, you would be more favorably inclined than before. And, if you were a public commentator, willing to state your views honestly, you would say so.

Does such a sceptic exist? I haven’t seen one, although I follow the debate fairly closely. In fact, in the 25 years or so in which I’ve been following the issue, I can only recall one instance of someone described as a “sceptic” changing their view in the light of the evidence. And of course, his fellow sceptics, who’d been promising that his research would reveal massive errors in the temperature record, immediately decided that he’d never really been one of them. In any case, while Muller was and remains a scientific sceptic, he’s no longer a climate sceptic.

Operationally, it’s clear that the term “climate sceptic” means someone whose criteria for convincing evidence are those set out by the Onion.

I’d be happy to be proved wrong (by counterexample), but as far as I can see, if the ordinary usage of the term “sceptic” is applied, the world population of genuine climate sceptics is zero.

Nuclear math doesn’t add up

by John Quiggin on July 20, 2016

Writing in the National Review, Robert Bryce< of the Manhattan Institute criticises the Democratic Party platform for omitting any mention of nuclear power, and accuses the Democrats of failing to “do the math”. Unfortunately, although he throws some numbers about, he doesn’t do any math to support his key conclusion

But even if we doubled the rate of growth for wind and solar — and came up with a perfect method of electricity storage (which of course, doesn’t exist) — those renewables aren’t going to replace nuclear energy any time soon
So, I’ll do the math for him.

Anti-militarism

by John Quiggin on July 4, 2016

100 years after the Battle of the Somme, it’s hard to see that much has been learned from the catastrophe of the Great War and the decades of slaughter that followed it. Rather than get bogged down (yet again) in specifics that invariably decline into arguments about who know more of the historical detail, I’m going to try a different approach, looking at the militarist ideology that gave us the War, and trying to articulate an anti-militarist alternative. Wikipedia offers a definition of militarism which, with the deletion of a single weasel word, seems to be entirely satisfactory and also seems to describe the dominant view of the political class, and much of the population in nearly every country in the world.

Militarism is the belief or desire of a government or people that a country should maintain a strong military capability and be prepared to use it aggressively[^1] to defend or promote national interests

Wikipedia isn’t as satisfactory (to me) on anti-militarism, so I’ll essentially reverse the definition above, and offer the following provisional definition

Anti-militarism is the belief or desire that a military expenditure should held to the minimum required to protect a country against armed attack and that, with the exception of self-defense, military power should not be used to promote national interests

I’d want to qualify this a bit, but it seems like a good starting point.

The Schengen option ?

by John Quiggin on June 28, 2016

Like most people outside Britain (and, it seems, like most British people, politicans and pundits as well as voters) I hadn’t paid a lot of attention to the detailed implications of a Leave vote until it actually happened. Now that it has happened, the details matter. In particular, it seems that Boris Johnson and other leaders of the Leave campaign (though presumably not UKIP) are hoping to promote either the “Switzerland” or “Norway” options. I thought I’d check on the implications of these options for migration policy and AFAICT, both Norway and Switzerland are Schengen visa countries. So, on the face of it, those Leavers who supported continued market access on the Norway/Switerland model have voted for removal of existing controls on migration rather than the imposition of new ones.

I assume that Johnson and others have in mind a negotiation in which Britain (or England) gets the market access bits of the Norway/Switzerland options, while maintaining the existing opt-outs negotiated as an EU member. But why should the EU offer this? In particular, if Scotland becomes independent and joins the EU, the Scots will presumably want to maintain free access to England, while the rest of the EU would be unlikely to allow Scotland to remain under English border controls. In any case, the whole logic of the EU position is that Britain should not be able to pick and choose.

On the basis of an admittedly perfunctory search, I haven’t been able to find more than passing discussion of this question. Can anyone point me to more comprehensive analysis?

Reaping the Whirlwind

by John Quiggin on June 26, 2016

I’ve been trying to make sense of the Brexit (or rather E-exit) vote in terms of the “three-party system” analysis I put forward a while back. The result, over the fold, is a piece in Inside Story, an Australian magazine.

The key point is, that, in the absence of a coherent left alternative, neoliberalism (hard and soft) is being overwhelmed by a tribalist backlash. Writing this, I realise it might be construed as criticism of Corbyn for failing to develop and propose such an alternative in the referendum campaign. That would be a bad misreading. The context of the referendum meant that it was always going to be a choice of evils: between the racism and bigotry that animated so much of the Leave campaign, and the neoliberalism of both the Cameron government and the EU. The option of a social democratic, or even soft neoliberal, EU was not on the ballot.

Look what they’ve done to my song, Ma

by John Quiggin on May 31, 2016

My discussion of intellectual property inevitably raised questions about my argument that property rights are not natural rights, but are socially constructed and, in the modern world, exist only as part of the legal structures created and enforced by states. The “moral rights” of artists over their creative works has been raised as a suggested counterexample. In fact, this example reinforces my original argument. Two cases arise, both of interest:

In the United States, the moral rights of artists were effectively unrecognised by law until accession to the Berne Convention 1989, and remain extremely limited. The result is that, once an artist has sold the rights to her work, she has no control over its subsequent use, unless she can make a case separate from moral rights, for example that use in an advertisement misrepresents the artist as endorsing the product. So, for example, it’s perfectly legal to use London Calling to advertise Jaguars, or to clip Fortunate Son to fit a jingoistic ad for jeans. Moral rights are widely recognised, and may generate social opprobrium for those who violate them (as with other misuses of property rights) but they have no legal standing.

In France and other European countries, artists have inalienable moral rights over their work, to prevent misuse of the work by the initial or later purchasers. This is not a property right, but a constraint on property rights. To the extent that moral rights are recognised after the fact, they constitute a taking from the purchaser of the property right. To the extent that they are recognised when artists sell rights to their work, they (like any restriction on alienation of property) represent a constraint on the property rights of the artist. Melanie Safka recognised this, in an ironic fashion, in her classic Look what they’ve done to my song, Mawhen she wrote

It’ll be all right ma, maybe it’ll be okay
Well, if the people are buying tears
I’ll be rich someday, ma

Coming back to the general issue, property rights and (perceived/socially accepted) natural rights have features that mean they tend to coincide in some ways and conflict in others. Most obviously, they are both associated with the general feeling of rightful possession, so that a system of property rights is more stable when it coincides with natural rights. On the other hand, natural rights are mostly perceived as inalienable and indivisible, while property in its ideal form is infinitely transferable and divisible. Moral rights for artists are a classical example of the clash between inalienability and unfettered property rights but the same clash arises at every point in the production process.

Trump and tribalism

by John Quiggin on May 23, 2016

Watching the rapid consolidation of the Republican Party around the candidacy of Donald Trump, I’ve tried to make sense of this in terms of the “three party system” analysis I presented a few months ago. I saw the Republicans as the “hard neoliberal” party relying on the votes of (white Christian) tribalists and making symbolic gestures in their direction, but largely ignoring them, particularly if their interests came into conflict with those of big business.

What’s become clear since then, I think, is that the Republican Party apparatus (politicians and party officials) is more tribalist than this analysis suggested. Faced with the prospect of electing their hated tribal enemy, Hillary Clinton, as President, the vast majority look like backing Trump (some, but not all of them, holding their nose as they do so).

From a hard neoliberal viewpoint, this makes no sense. Clinton’s Democratic Leadership Council background is that of the stereotypical soft neoliberal. Her candidacy is the best chance of maintaining the long-running alternation in office between the hard and soft variants of neoliberalism. Admittedly, she will be pulled to the left by the general shift exemplified by the Sanders insurgency, but she is unlikely to do anything that would fundamentally undermine capitalism. By contrast, a Trump takeover of the Republican Party would be a disaster for neoliberalism (which does not mean it would be good for the left). That would be the inevitable result of a Trump victory. Even a creditable defeat, which would be blamed on the old establishment, could leave the tribalists in control of the organization.

The only groups where the #NeverTrump analysis seems to hold sway are the business donor class and the remnants of the rightwing intelligentsia (hard to believe they were carrying all before them only 20 years ago). The donors obviously have no interest in throwing money at someone like Trump. As for the intelligentsia, even if they were willing to embrace Trump, it’s obvious he has no use for any but the most total hacks, and not even many of those.

A bit out of order, this is another draft extract from my book-in-progress, Economics in Two Lessons. It’s part of the chapter on income distribution, meant to follow the section on unions, and precede the Australia-US data point and the discussion of corporate profits. After this, I plan to conclude the “predistribution” part of the chapter with a discussion of intellectual “property”, then move on to “redistribution” through taxation and public expenditure.

As always, encouragement is welcome, constructive criticism even more so.

Over the fold, another extract from my book-in-progress, Economics in Two Lessons. Encouraging comments appreciated, constructive criticism even more so.

Predistribution and profits

As we’ve seen in previous sections, the social constructions of property rights and institutions surrounding employment makes a big difference to the determination of wages and working conditions. These social constructions affect ‘predistribution’, the distribution of income and wealth that arises before the effects of taxes and public expenditure are taken into account.

Predistribution is equally relevant to the other big source of personal income: profit derived from private businesses and corporations. Without legal structures designed specifically to protect businesses from the risks of failure, profits would be far less secure, and the difficulty of establishing and running a business much greater. Corporate profits are not a natural outcome of a market society, but the product of specific structures of property rights introduced to promote corporate enterprise.

The risks of running a business in the 18th century, and well into the 19th, were substantial and personal. There was no such thing as bankruptcy: a business failure meant debtors prison, where debtors could be held until they had worked off their debt via labor or secured outside funds to pay the balance.

After a brief and disastrous experiment in the early years of the 18th century (the South Sea Bubble), joint stock companies were also viewed with grave suspicion.

The prevailing view was Quoted in John Poynder, Literary Extracts (1844), vol. 1, p. 268. [1]

Corporations have neither bodies to be punished, nor souls to be condemned; they therefore do as they like.

This is often misquoted as

“Did you ever expect a corporation to have a conscience, when it has no soul to be damned, and no body to be kicked?

Adam Smith was similarly scathing, though with more of a focus on the principal-agent problem

The directors of such [joint-stock] companies, however, being the managers rather of other people’s money than of their own, it cannot well be expected, that they should watch over it with the same anxious vigilance with which the partners in a private copartnery frequently watch over their own…. Negligence and profusion, therefore, must always prevail, more or less, in the management of the affairs of such a company.

Exceptions were made only for specially authorised quasi-governmental ventures like the East India Company, focused on foreign trade. In general, limited liability companies were not permitted in Britain or most other countries. The partners in a business were jointly liable for all its debts.

These same rules applied in Britain’s American colonies and continued to prevail in the United States until the middle of the 19th century. The introduction of personal bankruptcy laws put an end to debtors prison, greatly reducing the risks of running a business. The creation of the limited liability company was an even more radical change.

These changes faced vigorous resistance from advocates of the free market. David Moss, in When All Else Fails, his brilliant history of government as the ultimate risk manager, describes how the advocates of unlimited personal responsibility for debt were overwhelmed by the needs of business in an industrial economy. The introduction of bankruptcy and limited liability laws took much of the risk out of starting and operating a business.

By contrast, in Economics in One Lesson, Hazlitt doesn’t mention limited liability or personal bankruptcy and seems to assume (like most defenders of the market) that these are a natural feature of market societies. More theoretically inclined propertarians have continued to debate the legitimacy of bankruptcy and limited liability laws, without reaching a conclusion.

This debate over whether bankruptcy and corporation laws are consistent with freedom of contract is really beside the point. The distribution of income and wealth is radically changed both by the existence of these institutions and by the details of their design. In particular, the massive accumulations of personal wealth made possible by capital gains from share ownership would simply not exist. Perhaps there would be comparable accumulations of wealth derived in some other way, but the owners of that wealth would be different people.

A crucial policy question, therefore, is whether current laws and policies relating to corporate bankruptcy and limited liability have promoted the growth of inequality and contributed to the weak and crisis-ridden economy that has characterised the 20th 21st century. The combination of these factors has produced absolute stagnation or decline in living standards for much of the US population and relative decline for all but the top few per cent.

There can be little doubt that this is the case. As recently as the 1970s, a corporate bankruptcy was the last resort for insolvent companies, typically leading to the liquidation of the company in question. As well as being a financial disaster, and a source of shame for all those involved. For this reason, nearly all major companies sought to maintain an investment-grade credit rating, indicating a judgement by ratings agencies that bankruptcy was, at most, a fairly remote possibility.

Since that time, bankruptcy has become a routine financial operation, used to avoid inconvenient liabilities like pension obligations to workers and the costs of cleaning up mine sites, among many others. The crucial innovation was “Chapter 11”, introduced in the Bankruptcy Reform Act of 1978.

The intended effect of Chapter 11 was that companies could reorganise themselves while going through bankruptcy, and re-emerge as going concerns. The (presumably) unintended effect was that corporate managers ceased to be scared of bankruptcy. This was reflected in the spectacular growth of the market for ‘junk bonds’, that is, securities with a high rate of interest reflecting a substantial probability of default. Once the preserve of fly-by-night operations, junk bonds (more politely called ‘high-yield’) became a standard source of finance even for companies in the S&P 500.

At the same time, legislative changes and the growth of global capital markets greatly enhanced the benefits of corporate structures, while eliminating many of the associated costs and limitations. At the bottom end of the scale, the ‘close corporation’ with only a handful of shareholders, became the standard method of organising a small business. This process was aided by a long-series of pro-corporate legislative changes and court decisions (notably in Delaware, which has long led the way in this process, and where vast numbers of US companies are incorporated). At the top end, the rise of global financial markets from the 1970s onwards allowed the creation of corporate structures of vast complexity, headquartered in tax havens and organised to resist scrutiny of any kind.

At the behest of these corporations, governments have negotiated agreements supposedly designed to ensure that corporate profits are not taxed twice in different jurisdictions. In reality, using a combination of complex corporate structures and governments (notably including those of Ireland and Luxembourg) eager to facilitate tax avoidance in return for a small slice of the proceeds, the effect has been to ensure that most global corporate profits are not taxed even once in the countries where they are earned.

What can be done to redress the balance that has been tipped so blatantly in favor of corporations. The obvious starting point is transparency. Havens of corporate secrecy, from Caribbean islands to US states like Delaware must be made to reveal he true ownership of corporations, in the same way that tax havens like Switzerland, used mostly by wealthy individuals, have been forced to disclose the ownership of previously secret accounts.

The use of complex corporate structures to avoid tax is a much more difficult problem to tackle. Some measures are being taken to attack what is called “Base Erosion and Profit Shifting’, but past experience suggests that slow-moving processes of this kind will at best keep pace with the development of new forms of avoidance and evasion. It’s necessary to re-examine the whole structure of global taxation agreements. Instead of focusing on the need to avoid taxing corporate profits twice, the central objective should be to ensure that they are taxed at least once, in the place where they are actually generated.

More generally, though, the idea that corporations are a natural part of the economic order, with all the human rights of individuals, and none of the obligations needs to be challenged. Limited liability corporations are creations of public policy, useful to the extent that they promote the efficient use of capital but dangerous to the extent that they facilitate gross inequalities of income and opportunity.

Why is global finance so profitable ?

by John Quiggin on May 9, 2016

In a recent post, I asserted that

activities like tax avoidance/evasion and regulatory arbitrage aren’t peripheral flaws in a financial system primarily concerned with the efficient global allocation of capital. They are the core business, without which the profits of the global financial sector would be a tiny fraction of the $1 trillion or so now reaped annually
As I’m working on income distribution issues my long-running book project, this seems like a good time to see if this claim can be backed up by hard numbers.

First up, here’s my source for the $1 trillion number (actually $920 billion). As a plausibility check, I’ve tried to estimate the total size of the global financial sector. Various sources, including Wikipedia estimate that the banking and insurance sector accounts for 7-8 per cent of US gross product. Extrapolating to world gross product of about $80 trillion that would give around $6 trillion for the total size of the sector. The US is almost certainly more financialised than the world as a whole. Still, the profit number looks about right. A trickier question is whether the rents accruing to managers and top professional in the sector should be counted as part of profits. I’d guess that these rents account for at least another $1 trillion, but I have no real idea how to test this – suggestions welcome.

Is tax avoidance/evasion and regulatory arbitrage a big enough activity to account for a substantial share of a trillion dollars a year? Gabriel Zucman estimates that there’s $7.5 trillion stashed in tax havens, of which around $6 trillion is untaxed. He estimates the tax avoided at $200 billion . I’ll estimate that half of that ($100 billion) is creamed off in financial sector, mostly as profits or rents. That implies a profit margin of a bit under 2 per cent, which seems reasonable.

Tax evasion by wealthy individuals is only a small part of the story. Legal tax avoidance is almost certainly more important. Most of that involves companies, but it’s important to distinguish between “close” corporations, which hide the activities of an individual or family and large global corporations. I don’t have any idea how to measure the cost of avoidance through close corporations. As regards global corporations, Zucman estimates that “a third of U.S. corporate profits, or $650 billion, are purportedly earned outside the country, with a cost to the US of $130 billion a year . Extrapolating to the world as a whole, that would be at least $500 billion. Again, assuming the financial sector creams off half of the sum, we get $250 billion (the fact that the finance sector itself accounts for around 40 per cent of all corporate profits means there’s a problem of recursion that I haven’t worked through)

Then there’s manipulation of exchange rate and bond markets. I have no idea how to measure this, but given that the notional volume of trade in some of the markets concerned is measured in the hundreds of trillions, it seems plausible that the profits and rents from market-rigging must be at least in the tens of billions.

These are probably the biggest scams, but there’s also regulatory arbitrage, privatization (a huge source of rent over recent decades), domestic tax avoidance and more.

Adding them up, I’d suggest that $500 billion a year is a low-end estimate for the profits and rents associated with various forms of anti-social financial sector activity.

There’s lots of potential error around these numbers, but the order of magnitude seems reasonable to me. As against the claim that the explosion in financial sector activity and profits over the past 40 years has been driven by the benefits of a more efficient allocation of capital by rational markets, the claim that it’s all about tax-dodging and socially unproductive arbitrage seems pretty plausible.

Obviously, the social cost of a financial system devoted to undermining tax and regulatory systems far exceeds the profits earned from the activity. That’s true of any kind of socially destructive, but privately profitable, activity. But the problem is greater in the case of financial sector activity because of the disastrous effects of financial crises.

Rubin gets it right

by John Quiggin on May 7, 2016

Crises upend all kinds of assumptions, and the crisis in the Republican Party is no exception. Who would have thought, for example, that the National Review crowd might end up voting for the Libertarian candidate while lots of self-described libertarians are backing Trump.

At least as surprising to me is that, among all the attempts from establishment Repubs to understand the disaster that has befallen them, the most insightful and accurate (that is, the closest to my own analysis) has come from Jennifer Rubin at the Washington Post, someone I’ve never before taken seriously. Unlike nearly all the NeverTrumpers she accepts the obvious implication of the fact that around half the Republican electorate has gone for Trump’s tribalism

The GOP discovered (in part, through Sen. Ted Cruz’s collapse despite perfect mechanical execution) that there is no majority supporting the Reagan agenda. Certainly, Cruz was a politician of limited talent and imagination, but if he could not sell the “three-legged stool” to the masses, perhaps there are no masses receptive to that sort of stuff. Even in a GOP primary, there is no majority looking to roll back gay rights or give huge tax breaks to upper-income Americans.
Second, she nails the role of climate change denialism in the intellectual collapse of the political right
Along with all of this, conservatives have to end their intellectual isolation and self-delusions. They need to stop pretending that climate change is not occurring (the extent and the proposed solutions can be rationally discussed) or imagining that there is a market for pre-New-Deal-size government. Conservatives must end their infatuation with phony news, crank conspiracy theories, demonization of well-meaning leaders and mean rhetoric
Contrast that with, say, Will and Krauthammer, who denounce Trump in extreme terms, but peddle lunatic conspiracy theories themselves.

In this context, I was struck by this piece headlined The outlandish conspiracy theories many of Donald Trump’s supporters believe. Despite the headline and the spin in the text, the data reported in the article shows that Trump supporters are only marginally more likely than Cruz and Kasich voters to accept the standard set of Republican conspiracy theories. To give a fairly typical example,

Fifty-two percent of his supporters said [the claim that vaccines cause autism] was possibly or definitely true, compared to 49 percent of those who supported Cruz and 45 percent of those who supported Kasich
These differences are barely outside the likely margin of error in a poll of this kind. The differences between groups of Repub voters on any given issue are far smaller than the differences arising from more or less extreme conspiracy theories (for example, only about 20 per cent of each group think that the Sandy Hook shootings were faked).

If there is one prediction that can safely be made it is that the Republican party of 2017 will be very different from that of 2015, before the Trump eruption. Whether it moves in the direction of sanity remains to be seen.

Pirates! (Militarism whack-a-mole #73)

by John Quiggin on May 2, 2016

Making the case against militarism is very reminiscent of climate denial whack-a-mole. Demolish one spurious argument, and you’re immediately presented with another. For example, my post showing that the economic benefits of “keeping sea lanes open” could not justify more than a trivial proportion of current naval expenditure, got hardly any substantive responses (apart from tiger-repelling rocks), but a great many saying “what about the pirates?”.

I’ve done the numbers on this one, and they look pretty clear-cut. There are a bunch of estimates on the web of the annual cost of piracy ranging from $1 billion to $16 billion a year.

This seems implausibly high. The amount actually stolen by pirates or paid as ransoms is far smaller, less than a billion a year at its peak, AFAICT. Looking in detail, there’s a fair bit of double counting here (both actual losses and the insurance premiums which offset them are counted, for example), and the high-end numbers typically include some estimate of the cost of naval deployments on anti-piracy patrols. In particular. Still, in the spirit of fair play, I’ll go with $10 billion.

Turning to the US Navy* budget, it’s currently over $150 billion a year. That supports a fleet of 272 “deployable battle force” ships, implying an annual cost of over $0.5 billion per ship. So, the annual cost of piracy is the same as the cost of about 20 ships. To put it another way, reducing the fleet by one ship, and scaling down anti-piracy operations accordingly would have to increase global piracy by 5 per cent to yield a loss to the global shipping industry greater than the savings to the US (I leave aside the question of why the global shipping industry is such an important recipient of US foreign aid).

Having played military whack-a-mole many times before I can anticipate the responses in my sleep. So, I’ll open the comments threads, resist the temptation to take part, and whack the inevitable moles in a later post.

  • The US spends more than other developed countries, but I don’t think the others get any more ship for their shilling, capability-adjusted.

** I’ve corrected some errors in the data I used in the original version. But the discussion made it pretty clear that the objections aren’t to the numbers but to the whole idea of weighing benefits and costs in anything to do with military expenditure.

A data point on minimum wages

by John Quiggin on April 28, 2016

I’m currently working on a section of my Economics in Two Lessons book dealing with minimum wages in the context of predistribution policies, so I thought I would compare Australia with the US, where the idea of a $15/hour minimum wage is currently a hot topic. In Australia there are two kinds of minimum wage. The PPP exchange rate is estimated at $A$1.30 = $US, which is fairly close to the market exchange rate at present, so I’ll give both $A and estimated $US equivalents

The standard minimum wage for workers aged 21 or over is $A17.29 hour ($US13.30) applying to employees under standard award conditions. These include four weeks annual leave, sick leave, employer contributions to pension plans and so on.

More comparable to the situation of US minimum wage workers are “casual” workers, employed on an hourly basis. Casual workers get a loading of at least 25 per cent, bringing the wage up to at least $A21.60 an hour ($US16.60), to compensate for the absence of leave entitlements. In addition, they have entitlements including:

  • “Penalty” rates for weekend and night work (usually a 50 per cent loading, 100 per cent on Sundays)
  • For workers employed on a regular basis, protection against unfair dismissal.

The policy question is: what impact have these high minimum wages had on employment and unemployment. That’s too big a question to answer comprehensively, but we can look at the obvious data points: the official unemployment rates (5.7 for Oz, 5.5 per cent US) and the 15-64 employment population ratios (72 per cent for Oz, 67 per cent US). So, it certainly doesn’t look as if the Australian labor market has been crippled by minimum wages.

Note: I’ll respond in advance to the widespread misconception that Australia is a special case due to mineral resources. Mining accounts for about 2 per cent of employment in Australia, and (because most mines are owned by multinationals) its contribution to Australian national income is also so, probably around 5 per cent.

  • Workers aged 18 get about 70 per cent of the adult minimum, equivalent to around $US11.50 for casuals. But the great majority of US minimum wage workers (about 80 per cent) are 20+.

Over the fold, an extract from my book-in-very slow-progress, Economics in Two Lessons. I’m getting closer to a complete draft, and I plan, Real Soon Now, to post the material so far in a more accessible form. But for the moment, I’ll toss up an extract which is, I hope, largely self-sufficient. Encouragement is welcome, constructive criticism even more so.
