As ever, the problem with Richard Murphy is that he has no knowledge of the subject under discussion

This is just a lovely example of what's so wrong with the various pronouncements of Richard Murphy, the confused soul behind Corbynomics:

And this opens up the space for him to suggest a wealth tax, in his imaginary budget. “It was inconceivable in the past. But as a result of the work that the Tax Justice Network has done opening up the world’s secrecy jurisdictions, now if people move their assets offshore, we can find them again.” He has other specific proposals – a tax to replace national insurance, which was designed around jobs that don’t exist any more, and “we would need to explore new taxes for the 21st century, which are largely untried. A progressive consumption tax, so people with very few transactions would have very low tax. We have to discourage conspicuous consumption, which is eating up our planet.”

He's just entirely unaware of all the other stuff that people have been thinking about economics and tax. The progressive consumption tax for example: it's generally thought of as a very good idea indeed. But not because it would reduce consumption, as he seems to assume. Rather, because it would make the future richer: that is, it would over time encourage more consumption.

The essential insight behind it is that investment increases the future size of the economy, consumption might provide that short term boost to demand, but investment is what really grows economies. And we also know that if you tax something then you get less of it: thus the progressive consumption tax aims to not tax investment, capital, or the returns to either.

What really happens is that anyones' savings end up inside a giant ISA or IRA style vehicle. Any additions to savings are not taxed in any manner. Any returns to such savings or investments that are reinvested are not taxed. Any income which is consumed, or any drawing down of savings which is then consumed (or, obviously, returns to capital which are then consumed) are taxed in much the same manner that income tax works now, at rising, progressive, rates.

The observant will note that this is not compatible with a wealth tax. Even the half awake will note that the effect of such a system is to not tax wealth. In fact, the entire point is to not tax wealth, but to allow it to roll up while invested so as to increase the wealth and income of the future society: and thus to increase the consumption opportunities of that future.

And this is the basic problem with all of Murphy's ideas. Other people too have thought about these various points and problems. And Murphy's entirely unaware, startlingly ignorant in fact, of the evidence found, logic used and conclusions reached by those others. Turning on the free money tree of Peoples' QE is monetisation of government spending and we know how that turns out. Capital allowances are in the tax system for good reason: because we tax businesses on their profits, not their turnover. A certain amount of both tax avoidance and tax evasion are going to be there simply because a society without either will have no liberty. And the point and purpose of a progressive consumption tax is so that we do not tax wealth, rather than that we do: and it is to make the future richer, encouraging more future consumption too.

It is this that really grates. Not just that we disagree with Murphy's assumptions and between dislike and abhor his suggestions, but that he proceeds without noting that tens of thousands of very clever people have ploughed these same furrows over the centuries. And he's simply flat out ignorant of the truths they have uncovered.

Recent books in the ASI's pile

The ASI receives more books than it can get round to giving a full review of, but here are some particular interesting recent ones you might want to check out.

• Imaginary Cities by Darran Anderson

Describing itself as a work of 'creative non-fiction' it's a wide-ranging thesis on the city. Get it if you love their wonderful twitter account.

• The Routledge Handbook of International Education and Development by Simon McGrath & Qing Gu (eds)

Probably one to look at in the library, given the price, this handbook seems to be the most authoritative work from practitioners and experts in the area; a more scholarly take on The Beautiful Tree.

• The Moral Case for Fossil Fuels by Alex Epstein

I'm really glad this book exists.

• Free Market Fairness by John Tomasi

Tyler Cowen says this is 'one of the very best philosophical treatments of libertarian thought, ever' and what can I add to that?

• The Long Process of Development: Building Markets and States in Pre-industrial England, Spain and their Colonies by Jerry F. Hough & Robin Grier

The list of reviews on the back is very impressive: Dani Rodrik, Mike Munger, Lant Pritchett, Tyler Cowen, and the topic is hugely interesting.

Some ideas do take a long time to be discovered, don't they?

Owen Paterson is telling us all about a lovely new idea:

For the past 50 years the environmental movement has been in thrall to a simple, powerful and utterly wrong idea: that the best way to save the planet is to curtail human activity, whether in the form of breeding, building, burning or business. Anybody who suggests a different strategy – that economic activity is not just compatible with environmental benefits, but vital to creating and improving them – has been howled down.

But that is changing, and a new idea is gaining ground, under the term “Ecomodernism”. The key idea behind Ecomodernism is that the more technology human beings adopt, the more they can decouple from dependence on the natural environment and live lives that are prosperous but green. The great Green Blob that dominates the public and NGO sector, whose reactionary tendencies I referred to when I left office as Environment Secretary last year, still refuses to recognise this.

That phrase, Great Green Blob, needs a bit of work before it's going to become a propagandistic rallying cry we think. And while we obviously agree with the basic thought, given that we've said as much ourselves repeatedly, we're not quite sure it's a new idea. Not just because we've said it before, but because it's in the very foundational document of the whole global warming movement. That document being the special Report on Emissions Scenarios, the economic models that tell us how many people there will be, at what level of wealth, using what technologies, thus giving us the emissions levels that can be fed into those computer models.

And here is what the SRES says about a richer, higher tech, world:

In the A1 scenario family, demographic and economic trends are closely linked, as affluence is correlated with long life and small families (low mortality and low fertility). Global population grows to some nine billion by 2050 and declines to about seven billion by 2100. Average age increases, with the needs of retired people met mainly through their accumulated savings in private pension systems.

The global economy expands at an average annual rate of about 3% to 2100, reaching around US$550 trillion (all dollar amounts herein are expressed in 1990 dollars, unless stated otherwise). This is approximately the same as average global growth since 1850, although the conditions that lead to this global growth in productivity and per capita incomes in the scenario are unparalleled in history. Global average income per capita reaches about US$21,000 by 2050. While the high average level of income per capita contributes to a great improvement in the overall health and social conditions of the majority of people, this world is not necessarily devoid of problems. In particular, many communities could face some of the problems of social exclusion encountered in the wealthiest countries during the 20 th century, and in many places income growth could produce increased pressure on the global commons.

Energy and mineral resources are abundant in this scenario family because of rapid technical progress, which both reduces the resources needed to produce a given level of output and increases the economically recoverable reserves. Final energy intensity (energy use per unit of GDP) decreases at an average annual rate of 1.3%. Environmental amenities are valued and rapid technological progress "frees" natural resources currently devoted to provision of human needs for other purposes. The concept of environmental quality changes in this storyline from the current emphasis on "conservation" of nature to active "management" of natural and environmental services, which increases ecologic resilience.

A richer world is a greener world: exactly what Paterson is saying. But this isn't anything new at all, the SRES is a quarter century old. It is also, as above, the document that feeds into the whole IPCC process. It's not just that this is a possibility, this is an assumption that has been made before we ever started worrying about Flipper boiling alongside that last ice floe.

To our mind this is the most important part of it. If one abandons this assumption that this richer world will be that greener world then one must abandon all of the research that is based upon this assumption. Which means, really it does mean, each and every piece and part of the current global warming hypothesis. Because that entire edifice has indeed been built upon this assumption: the other economic models, for example the A2 one upon which the Stern Review is based, show that a less rich world is also a less green one.

And what's really lovely about these models is that if we follow the B2 path, less globalisation, more localisation, much slower economic growth, essentially the Green manifesto, then the outcome is even worse. And these are not some rogue models: they are the very assumptions that the entire structure is built upon.

How'd'ye like them apples?

The housing crisis has a simple solution: build, baby, build

Over at the IB Times I've written about the government's housing targets (not worth the paper they're written on, basically), and why we want to concrete over the green belt – well, at least some of it:

By freeing up green belt land the supply of housing could grow enough to let prices fall considerably. All of this would actually require very little green belt land to be built on – less than 1.5% of it would give us the space we'd need to build an extra 1.4 million new homes. We could build one million homes around London on just 3.7% of the capital's green belt.

Could the private sector do it? It already has – during the 1930s housing boom, private construction rose from 133,000 houses per year in 1934-45 to 279,000, in just one year – and these houses were affordable. If you come, they will built it.

The cost of extra infrastructure could be more than covered by capturing "planning gain", with the government buying green belt land, reclassifying it and selling it at the market rate to the private sector, keeping the gains for itself.

Trimming the edges of the green belt would suffice, but I'd like to go further. Much of the countryside is worth protecting, but much of the green belt itself is not. It doesn't provide amenity to anyone who doesn't live there already, it's bad for the environment, and it makes housing cripplingly expensive.

Read the whole thing. I've tried to make it as comprehensive as possible, as a useful 'cut out and keep' piece to send to people who haven't thought about how easily we could solve the housing crisis.

At last, now we know what's too expensive for renewable energy

An interesting article in The Guardian insisting that the Swansea tidal barrage should be junked. Not that they quite put it that way but that is what their argument means. What they're actually saying, these Green glitterati, is that the Hinkley C reactor should not go ahead:

So how do the operators, the French company EDF, expect Hinkley C – even if it can be built – to be economically viable? By extracting from the government a price guarantee of £92.50 per megawatt hour for the electricity it produces, index-linked for 35 years.

This is simply astronomical. It is more than twice the current wholesale price of electricity, and more than the government is now paying for solar power, whose costs are expected to fall greatly during the lifetime of the nuclear plant. Against current prices, the government’s guarantee represents a subsidy of over £1 billion a year.

OK, let's accept that that is too expensive. And that the usual argument, that prototypes always cost more doesn't really work here:

EDF argues that, as it learns from experience elsewhere, the cost of construction will come down. But the problem with the design is that these plants have to be built almost entirely on site, so each power station is, in effect, a one-off. The costs of technology fall when modular construction is possible: turning out identical units in a factory.

Fine, let us, as usual, accept their arguments at face value and then consider the implications of this. For example, Swansea:

Mandarins from the Department of Energy and Climate Change (DECC) and the Treasury are poring over the details before deciding whether it should be funded though a ‘contract for difference’ scheme.

The cost of lagoon power – a predicted £168 per MW/hour – is considerably higher than for offshore wind, or the £92.50 for nuclear.

If £92.50 is too high then £168 is definitely too high, isn't it? Thus, based upon the impeccable logic presented to us by Mssrs. Lynas, Monbiot and Goodall, the Swansea Barrage scheme is a dead duck, isn't it?

We look forward to these fine gentlemen making their opposition clear in due course. For, as they say:

Yes, we are still pro-renewables. But not at any price.

Putting the brakes on railway nationalisation

The new Labour Party leader Jeremy Corbyn wants to re-nationalise the railways? It is a political totem for the Left, of course. But is there an economic case too? The main economic argument made for nationalisation is that private providers have to make a profit, so a private service is necessarily more expensive. But this is untrue. Where there is competition, the need to make a profit is what drives improvement by pushing private providers to deliver better services cheaper. If they do not keep improving, they will lose business their competitors. In the case of rail, that means other companies who would be delighted to win franchises off them.

Remember too that investing in a service that has to keep improving in order to keep its customers is expensive. Investors quite reasonably expect a profit in return for giving up and risking their capital in such an enterprise. If the government did not generate the same profit, it would, in reality, be subsidising the industry – at taxpayers' expense. So there really is little or no 'saving' to be made.

Another argument is that a nation-wide service would reap economies of scale. But remember that there are diseconomies of scale too: large state industries are notoriously hard to manage. And any supposed economies would soon be eclipsed by inefficiencies when there are no competitors to keep the provider on its toes.

The old British Rail, of course, did not make profits at all; indeed, it made a large annual loss. It was inefficient and vastly overstaffed, and yet survived. As with other nationalised industries, the problem was that decisions were made politically.

In the first place, a nationalised industry has to compete for investment with other government departments and services. Spending decisions owe more to the political necessities of the moment (like elections) than long-term investment strategy. Second, politicians fear that cutting staff costs causes them political problems, while cuts in capital investment are barely noticed: the service just gets slowly less reliable. Third, the lack of competition in a nationalised service gives huge strike-threat power to the staff yet leaves service users with no power take their custom elsewhere. And the lack of competition means that there is no pressure to change, to adapt to customer needs, stay up to date, modernise and cut costs.

Even where, for practical reasons, competition is limited (as in railways), the public is better served by an independent regulator scrutinising private providers than a nationalised industry responsible only to ministers and Parliament. The independent regulator can fearlessly point out when things are not up to standard. The minister, being responsible for the provision of the service, will never admit to failures. And independent regulators can become highly expert on every aspect of the sector they regulate – transient ministers with many other responsibilities cannot.

Competition, of course, is the best regulator, and much can be done to improve competition in most industries that have been privatised, including railways. Competition opens each and every part of the service provision up to scrutiny – and potential replacement – by others.

Prior to 1992, just a couple of years before the rail industry was privatised, British Rail did not even bother to keep punctuality figures. Is there a more eloquent statement of the dismal nature of nationalisation?

Better information makes drugs markets work better: so why not legalise them to make them work even better?

Over at Quartz there's a fascinating piece where the economist meets the pot dealer. And the two discuss how the dark net, the use of Tor and illicit drugs markets on it, improve the markets for drugs. Now, of course, it's entirely possible to insist that drugs are fer' the devil and we should simply stamp it all out. And given that no human society yet has managed to do that that's probably not going to be successful. That idea also doesn't address our own belief that consenting adults should be allowed to ingest what consenting adults wish to ingest: it is, after all, their own body doing the ownership and we're all pretty sure these days that no one, not even the state, owns the body of a consenting adult other than that consenting adult. Given those two, it is therefore interesting to see what happens when dealers need to stand by their product and reputation is important:

The root cause of this market inefficiency is information asymmetry. You don’t know how good an illegal drug is until you consume it, and you can’t turn to the law to enforce agreements, return a substandard product, or complain to your dealer if he tries to rob you. That prevents price discovery and risk compensation, key features of a well-functioning market.

What makes the dark web a game-changer is that it has those features. Suppliers have detailed reviews on their product, the market is competitive, and people can shop around easily. Aspiring sellers struggle to get a foothold without a history of good reviews; sometimes they offer special deals and an easy exchange policy in return for good reviews. And the markets are global, so it’s possible to see prices in other countries. All this produces a well-behaved price distribution like the one you’d find in any functional, legal market.

Assuming that those are all features that we'd like to have where consenting adults do as consenting adults do, that's a good argument for the legalisation, not just the decriminalisation, of drugs. For while these illegal markets do work by reputation, just as brands do for many consumer items (and in exactly the same manner too) it is of course better to have such promises baked up by the usual resources of the civil law.

as above, some part of the opposition to the taking of drugs is simply this idea that people shouldn't. Which is a projection of personal desires onto the lives of other which we do not think has a part of a liberal society. Once that is over come then we want the provision of whatever it is to be as efficient and simple, with the greatest consumer protections, as possible. And given the way that these illegal markets are developing, we can see how they would continue to develop if legal. Towards being markets much like those for toothpaste and canned soup. Reliant upon reputation, delivery, quality, rather than who has the most and most violent thugs to control a particular territory.

We find it difficult to imagine why anyone would be against such beneficial developments quite frankly.

New ASI Paper: "Utility Gains: Assessing the Record of Britain’s Privatized Utilities"

A new Adam Smith Institute paper, “Utility Gains: Assessing the Record of Britain’s Privatized Utilities” assesses the various utility sales of telecoms, gas, water and electricity companies during the 1980's and 1990's and looks at how government, shareholders and customers fared since the privatisation process. The paper argues that the following benefits occurred for each stakeholder:

For the government – various general benefits accrued, such as a pronounced surge in investment. It benefited financially, both from one-off sales proceeds and from ongoing sizeable Corporation Tax receipts.

For shareholders, like pension funds, have generally done very well, with many privatizations – particularly the 12 RECs – heavily outperforming the FTSE 100. Privatized water stocks, too, have powered ahead. There are a few notable exceptions to this, such as Railtrack, British Energy and British Telecom.

For utility customers the financial benefits have been less tangible – in a period of massively rising wholesale prices there has been little to pass on. But investment has been much higher and much-needed improvements in customer service have been developed. Telecoms prices have actually fallen materially, while domestic gas, water and electricity prices have all risen sharply in real terms. However, domestic energy prices have risen mainly due to much higher wholesale gas costs – not because of private sector ownership.

The paper finds investment in utilities is now much higher than before privatization, especially in the electricity distribution and water sectors. In the latter case, substantial real price increases have helped finance this investment which had been woefully inadequate prior to privatization in 1989. Over the 25-year period, roughly £110 billion has been invested in the water sector, with the overwhelming majority of this sum being spent by the ten privatized water companies. Currently, over £4 billion per year is being invested.

The paper argues that the privatisation of utilities also created an innovation spike, specifically in the telecoms sector. Privatising British Telecom in 1984, it argues, created a new industry as the staid former Post Office subsidiary started to participate in an international marketplace, in which mobile telephony was developing at a rapid pace. Within a few years, Vodafone had become the pioneer of mobile telephony to such an extent that, by 1999, it had become the fourth most valuable company in history within just two decades of its founding. Had British Telecom remained state-owned, it is probable that the broadband rollout would have been delayed even further.

Misunderstanding why people tutor their children

The latest horror to assail our civilisation is apparently the idea that parents might hire tutors for their children. No doubt it's the upper middle classes deploying their superior financial resources to make sure that their own special little snowflakes get ahead in the race to grasp the great big brass ring that status and position offer in our society.

In those circumstances, it matters that an ethnic divide is opening up.

Quite right: if those with an enhanced melanin content are being held back by the privileges going to the melanin deficient then this is indeed something we should act upon. Do something about even. Perhaps we should ban private tutorials? Or possibly even reform the education system itself so that none is needed?

We would go with that second option ourselves: all taxpayers cough up for the current publicly funded education system so, yes, all should benefit from the best it has to offer. Except there's one little wrinkle to this:

From the age of 11, as many as 22% of UK children are seeing tutors. But there is a big gap between, on the one hand white children (20%) and, on the other, black children (47%) and Chinese children (48%).

It is not those pinkish hued upper middle classes who are giving their snowflakes a leg up. Given the population distribution in the country, with ethnic minorities largely concentrated into the inner cities, it's actually the people suffering under the yoke of the inner city school systems that are attempting to make up for the deficiencies of those inner city school systems.

The answer thus is not to ban private tutoring but to set off more than a few rockets under those running the inner city school systems.

Although we agree, that's always an unlikely conclusion to a Guardian article....

Getting the effect of cash entirely wrong

An amusing proof that it's possible to start from an interesting place and then fall over into complete nonsense. The point at issue being that the amount of cash floating around the British economy has increased in recent years. OK, well, why, and what, if anything, might we want to do about it?

The chief cashier of the Bank of England says that only about a quarter of the cash they put into circulation is used to buy and sell things. The rest of it is either shipped overseas – which we will put to one side for the moment – kept outside of the banking system ie (hoarded), or used to support the shadow economy (iestashed). In other words, not in circulation at all but stuffed under mattresses.

If you look at the trend growth of that cash “in circulation” over the last few years, it has accelerated past GDP growth as well as past the amount of money being taken out of ATM machines. And we also know that the use of cash in retailing has continued to fall steadily. That means the “cash gap”, between the small amount of cash that is used to support the needs of commerce and the large amounts of cash that are used for other purposes, has been growing. The interesting question is: why?

There are two pretty simple alternatives. If the amount of cash that is being hoarded has been growing, that would suggest people have lost confidence in formal financial services. Or, that they have so little knowledge of basic arithmetic that they are happy to have inflation eat away their store of value while forgoing the safety and security of bank deposits, no matter what value of the interest paid.

Well, no, not really, a bit of elementary economics would tell us that when interest rates are on the floor, as they have been "over the last few years", and inflation has been notable by its absence, then people will be more willing to hold cash, even just inert cash, than when they could have stuck it in the bank and got some interest to over the losses from inflation. So, actually, an increase in cash in circulation is just what we would have expected in recent years. And we've not even any evidence that this produces an increase in the financing of the grey or black economies: after all, our general analysis of monetary conditions currently is that the velocity of circulation has fallen. Meaning that we need more cash to finance the same amount of activity: just as we need more base money to finance the rest of the economy which is why QE.

So, the terrors are unproven. But what really boggles is this:

Charles and Jonathan estimate that the grey economy in the UK could have expanded by about 3% of UK GDP since the beginning of the current financial crisis. That means there are an awful lot of people not paying tax, and simple calculations will show that the tax lost that can be attributed to cash is vastly greater than the seigniorage earned by the Bank of England – the money the bank earns from issuing notes. Cash makes the government considerably worse off – and that means us.

It's that last phrase. We are not the government and the government is not us. It's not necessary to come over all entirely Mancur Olson to note this. If the government has insufficient money to defend the nation that might indeed impact us in a negative manner, if it's not got enough to finance Ed Miliband's pension then that's of less impact upon the rest of us.

And, clearly, if government is sucking less money out from our own economic activities to finance those of Ed Miliband then we are better off (even if Ed and Justine are not).

Another way of putting this is that it is not true that everything belongs to the government and we only get what is left after its exactions. Even if the grey and or black markets are expanding this does not make us worse off: it is, after all, difficult to see how an expansion of economic activity does make us worse off.

There is a deeper point behind all of this which is that there are those entirely seriously suggesting that in the near future the country should simply stop using cash. In order, so it is said, to crack down on the horrors that is tax evasion. Which is silly in one manner, because cash is simply a method of keeping score of who owes what to whom, as is all money. And if people are denied one method of doing so then another will be invented. But the part that horrifies us is this idea that the erasure of tax evasion would be worth the the erosion of the simple freedom to truck and barter as one wishes. Where all transactions, even the most minor, would be open to both the examination of the State and the payment of its tithe.

Yes, we really are saying that some level of tax evasion is the only outcome consistent with the maintenance of the general liberty. And we'd rather have that general liberty than we would the payment of the supposedly proper tithes, thank you very much.
