Today's Oxfam report says increasing inequality increases inequality

We suspect that Oxfam might want to think a little bit more about this part of their report today:

Research carried out for Oxfam by the London School of Economics, to be published later this year, shows empirical evidence that poverty rates tend to be higher when inequality is higher and increases in income inequality are associated with increases in income poverty rates.

Err, yes, we suppose so.

Poverty in the UK is a relative measure. Less than 60% of median household income adjusted for household size (and often after housing costs). This is a measure of inequality, not one of poverty.

Thus the actual information content of that coming report is that increasing inequality increases inequality.

Err, yes, we suppose so really.


A first stab at explaining the surging money supply

Allister Heath is getting worried over the surging money supply. It's entirely possible that he's right to worry as well. What follows is not *the* way to think about this. It is, rather, *a* way to walk through the basics of the subject.

Think of the equation MV = PQ. Money times the velocity of circulation equals prices times quantity demanded. One way to think of monetary policy is that to try to gee up the economy we try to increase V - we do this by lowering the interest rate. Thus, hopefully, Q increases. Similarly, if P is rising, that is we've got inflation, raise interest rates so as to reduce V and thus stop the rise  in P.

Again, please note that proper monetary economists will have conniption fits at this explanation. We're really trying perhaps too hard to make it simple.

We can also simplify what we mean by "money supply". M in that equation should be thought of as M0 in the national statistics. Notes and coins and central bank reserves sorta stuff. And MV can be thought of as M4, which is M0 plus all the stuff the banking system does, loans and debts and credit and so on. Again, not right but useful as an aide memoire.

Which brings us to the recent unpleasantness. Interest rates were already near or at rock bottom. But we could see that V was plummeting. We were really rather worried about a very deep recession (Q falling) and or deflation (P falling). And the solution there is to create lots more M so that MV doesn't shrink.

Which is one way of describing what QE was and is. The Bank of England makes up some more money and goes and buys stuff with it. Simple because it has made more M0, thus MV is larger than it would be if V fell but there was no increase in M.

All of which is great. But there will come a time when V returns to something like normal. and what we don't want to have is some great overhang of M which when timesed by that now resurgent V leads to massive increases in P - because it won't turn up as Q rising 20% a year, that's for sure. That's where the so far at least unmet predictions of QE causing galloping inflation come from. It presupposes that V returns to normal, of which there's no sign yet. Or, as Heath worries, perhaps there is:

Lilico provides context for this. The 14.7pc rate of increase is a new record for this statistical series, launched in 2009. Looking at an earlier and closely comparable statistical series, the strongest rate of growth in recent history was in 2006, at the height of the pre-crash madness, when the money supply surged by 12.8pc, a jump now widely understood to have been scandalously out of control.

There are other possible explanations for this. But the above is, while a scandalously simplified explanation, a possible one. Our whole aim in doing QE was to protect the economy against that fall in V. The reason it was QE rather than going out and spending the cash is because we wanted to be able to reverse the increase in the money supply (and QE has increased M0 a number of times, it's not just a small percentage increase) if, as and or when, V recovered to more normal levels.

Thus, if V has or is recovering in order to avoid that galloping increase in P we will want to reduce M. That is, reverse QE. The Bank of England will, assuming that this is the right explanation of course, sell the gilts they have and cancel the money they collect from doing so. Or, perhaps, simply not replace maturing gilts as they currently do, thus reducing their stock of gilts over time - this will have the same effect on M as the government will have to issue new gilts to the public to replace those maturing that the Bank holds. 

That is, if the money supply is booming because matters monetary are getting back to normal then the answer is for matters monetary to get back to normal. QE was a response to extraordinary times and if they're leaving the stage then so should QE.


Just what is the problem with grammar schools?

We find the current furore over grammar schools to be puzzling, difficult to understand.

Take this in the Observer. They note, correctly, that Upper Bavaria has an astonishingly low youth unemployment rate of only 3.4%. They credit, correctly, the education system:

Germany’s much-admired dual education system (in which apprentices are trained jointly by employers and at specialist vocational schools) has grown in Upper Bavaria, not because it was seen as the more responsible thing to do, but because companies, unable to “buy in” a fully trained-up workforce, often had to mould the workers they needed themselves.

That education system is dual in another manner too:

 The Gymnasium is designed to prepare pupils for higher education and finishes with the final examination Abitur, after grade 12, mostly year 13. The Realschule has a broader range of emphasis for intermediate pupils and finishes with the final examination Mittlere Reife, after grade 10; the Hauptschule prepares pupils for vocational education and finishes with the final examinationHauptschulabschluss, after grade 9 and the Realschulabschluss after grade 10.

Perhaps not dual then but there's a definite separation into academic and vocational streams - streams which go to different schools. And this is a much-admired system which leads to a 3.4% youth unemployment rate.

Yet mention grammars in Britain, the equivalent of those gymnasium (and common across much of central Europe too) and we are discussing the very devil, encouraging the destruction of all that is good and holy in our society.

We don't understand it. Our assumption is that it must have something to do with left wing politics - we find that's the usual explanation for beliefs entirely at variance with reality.


How to make public policy these days

The TL:DR version of how to influence public policy these days. Ride hobby horse, spout piffle, invent targets then shout loudly.

You might think we are joking but sadly not. For this is exactly what is happening over sugar.

The hobby horse is, as we have mentioned many a time, the insistence that it is sugar which is causing all that obesity out there. This cannot be true given that calorie intake and sugar intake are both down on the levels of the past. It cannot be rising consumption which is the cause as consumption hasn't been rising.

The spout piffle part is to insist that it is:

 Many believe sugar is the biggest contributor to the obesity epidemic crippling the NHS, and the results, published on Friday, reignited criticism of the failure by the government to take a stronger line in its childhood obesity strategy.

It isn't, as we've been saying. The inventing targets:

Britons are advised that sugar should account for no more than 5% of daily calories, but from 2012-14, the average was 13.4% for those aged between four and 10, 15.2% among 11- to 18-year-olds, 12.3% for adults under 65 and 11.1% for those aged 65 and over, the national diet and nutrition survey (NDNS) found.

This is a particularly cute one because the target itself, that 5%, was only invented after the period being described. It was only invented last year:

Dietary sugar should account for no more than 5% of daily calories consumed, half the previous recommended limit, the UK’s official nutrition advisers have said.

Note again, it's not just that the target is entirely pulled from some nether region it's that it didn't even exist, let alone apply to, the time period being examined. And then finally the shouting louder:

The Action on Sugar chairman, Graham MacGregor, a professor of cardiovascular medicine at Queen Mary University of London, said: “Today’s NDNS data shows that children are still consuming almost three times more sugar than the daily maximum recommendation. Theresa May must urgently rethink her pathetic childhood obesity plan that lacks restrictions on the marketing of, and promotions on, products high in saturated fat, sugar and salt.

“The strategy must include the implementation of the soft drinks industry levyand a mandatory reformulation programme, as the failed responsibility deal has already proven that a voluntary system does not work.”

We're not meeting an invented target, one that we've only just invented, which shows that compulsion is required to get everyone doing as we wish.

We really don't think this is a sensible way to run a country if we're honest. If it were possible we'd insist these campaigners spend more time with their train sets - there is at least an acknowledged role for the Fat Controller there. In the absence of that being possible we feel they should best be left to howl in the wilderness - and certainly not taken seriously.


Two particularly stupid views of trade in one morning

It's rare to be treated to two pieces of stupidity about trade on the same day but here we are, the event has happened. And sadly the people in error are people who do have at least some modicum of power over our lives. 

The error being made is to be mercantilist. To think that it is the exports which are the purpose of trade, the exports which make us rich. This is, as we all know, precisely the view which Adam Smith railed against that 240 years ago and Adam Smith was right. Both in what he said and in said railing. For it is, of course, the imports which make us rich, the reason we trade is to gain access to those imports.

Here is Liam Fox:

“If you want to share in the prosperity of our country, you have a duty to contribute to the prosperity of our country,” he is reported as saying, hinting that companies that do not take advantage of new export opportunities could face sanctions.

Clearly thinking that it is exporting which makes Britain rich:

He added: “We’ve got to change the culture in our country. People have got to stop thinking about exporting as an opportunity and start thinking about it as a duty — companies who could be contributing to our national prosperity but choose not to because it might be too difficult or too time-consuming or because they can’t play golf on a Friday afternoon.”

Again, exporting being equated with increasing the wealth of the nation. From the other side of the Channel we have M. Macron who is an odds on runner for the French Presidency:

British-based financial institutions must be prevented post-Brexit from selling their services in the eurozone, Emmanuel Macron, the likely progressive left candidate for the French presidency has told the Guardian.

This is the same mistake. It is to think that the British companies doing the exporting are the beneficiaries of such exports. When nothing is further from the truth. Those who benefit are the consumers who get to enjoy the imports. for that is why we do this trade thing - in order to gain access to those things which Johnny Foreigner does better or cheaper than we do. And that's the only reason we do trade too.

It gets worse:

But Macron insisted:

“The financial passport is part of full access to the EU market and a precondition for that is the contribution to the EU budget. That has been the case in Norway and in Switzerland. That is clear.” The proposal would be rejected outright by British Eurosceptics.

The insistence is that being able to sell to people is a privilege, one that a government must pay for so that businesses may do so. But this is incorrect - the benefit is to those who may buy the imports.

By not grasping the most basic point about trade M. Macron is threatening to hold the people of the European Union hostage unless some gelt is paid to the Brussels bureaucracy. He really is shouting that he'll make Europeans poorer unless the Brits give him some money. Such is the lunacy one is driven to by not understanding the basics of trade.

It has been 240 years now since the Wealth of Nations was published. We'd really rather hoped that people had grasped the point by now.

Re-dressing old wounds: The unintended consequences of NHS prescription regulations

Re-dressing old wounds: The unintended consequences of NHS prescription regulations

The current system for exempting certain patients from paying for their NHS prescriptions is discriminatory, unjust and unfit for purpose.  The high cost of prescription medication deters many patients from engaging consistently with treatment, increasing their risk of adverse outcomes such as strokes and heart attacks. 

When Bevan introduced the NHS in 1948, his intentions were clear and noble: nobody in this country should suffer from a treatable illness or ameliorable impairment because they were too poor to afford care. 

Why Europeans really do need American healthcare

Psychiatrist and blogger Scott Alexander has been on a tear lately about the price of pharmaceuticals in America, in particular the EpiPen, a common device used to treat people who have had severe allergic reactions. The EpiPen’s price has been hiked by about 400% since 2007, which left-wing website Vox blames America’s lack of price controls for but Scott blames on America’s cronyish regulation:

Let me ask Vox a question: when was the last time that America’s chair industry hiked the price of chairs 400% and suddenly nobody in the country could afford to sit down? When was the last time that the mug industry decided to charge $300 per cup, and everyone had to drink coffee straight from the pot or face bankruptcy? When was the last time greedy shoe executives forced most Americans to go barefoot? And why do you think that is?

It’s a fascinating piece and worth reading in full.

But what I’m really interested in is a part of his follow-up piece where he looks at rates of pharmaceutical innovation in the US, compared to countries with price controls:

1. Golec & Vernon (2006) say that as a result of European drug price regulation, “EU consumers enjoyed much lower pharmaceutical price inflation, however, at a cost of 46 fewer new medicines introduced by EU firms [over a 19 year period].”
2. Eger and Mahlich (2014) find that among pharmaceutical companies, “a higher presence in Europe is associated with lower R&D investments. The results can be interpreted as further evidence of the deteriorating effect of regulation on firm’s incentives to invest in R&D.”
So by my count, there are eight-and-a-half studies concluding that price regulation would hurt new drug innovation, and one-half of a study concluding that it wouldn’t. I’ve tried to eliminate all the studies sponsored by the pharmaceutical industry from this list, but I might have missed some.

Scott also cites an impressive-looking RAND Corporation paper which tries to project the consequences of government price-caps in healthcare.

In the short-term, things get better – drugs are cheaper. Great! But in the longer-term, things get worse. Much worse. Innovation declines and life expectancies fall in both the US and Europe.

Which makes me think that, as bad as the US system is in many ways, there’s a very important silver lining. All that money and intellectual property protection create much, much bigger incentives for healthcare innovation in the US than in Europe.

And that allows those of us in price-controlled countries to get something like the best of both worlds: cheap(er) drugs, but lots of research for new drugs, funded by our less fortunate friends in the United States. In a very important sense, it looks as if we’re free riding on American healthcare spending.

None of which is to say that the US system isn’t a dog’s dinner. Read Scott’s posts to get a flavour of that. But it does make smug posts and charts like the one above, which laugh at the nutty Americans and their wild, wasteful overspending, look quite silly. Without Americans spending all that money on healthcare, those of us living in price-controlled European systems would be living shorter lives, too.

The dirty little secret about GDP

An interesting point made in The Times about GDP:

For even GDP — the greatest, most definitive statistic of all — is really just a survey too. Forms are posted out to a selection of companies where they are filled in and sent or faxed back (“Informed estimates are sufficient for our needs”, says the bumf). Those figures go into a model and soon enough they become GDP. The size of Britain’s economy, the question of whether we are in or out of recession, the fate of governments — ultimately it all hangs on a questionnaire.

Well, yes, obviously it's a survey for as Hayek pointed out we cannot possibly gain enough information to really measure something as complex as an economy. There is the idea that we should move more to tax data - but the problem with that is that we know very well that people lie about taxes.

But there's actually something much more important than this. GDP isn't what we're interested in. It's a proxy, an interesting and useful proxy but a proxy all the same.

What we want to know is "How well off are the people?" We want to know this so that we can consider whether what we're doing makes them better off again or not. And our problem with GDP is that we're measuring things at market prices. What people actually pay for things.

Yet we know very well that this is not the price at which people actually value something. If a producer were able to price discriminate so that we each paid exactly what something was worth to us then it would be of course. And they attempt this. VW sells much the same car under the Skoda, VW, Audi and so on brands, each at a different price, in an attempt to do such price discrimination. But it doesn't work entirely.

The usual rule of thumb is that this consumer surplus, this value that we gain but which we don't have to pay for, is about equal to recorded GDP. So our consumption value is really some 200% of recorded GDP.

Which is where our problem comes in. Because the digital world would appear to be changing that multiplier. WhatsApp appears in GDP as something like $30 million, $50 million. There's no sales of it, no revenue from it, just the cost of the engineers working on it. And yet this is something that a billion people use for their telecoms needs, or some of them. The value in actual human value as consumption is obviously more than $100 million a year.

We must therefore remember not only that GDP is a proxy for what we really want to know but also that it's becoming an ever less reliable one.

Food of the Future: Chinese Food Security and the Opportunities of Brexit

Food of the Future: Chinese Food Security and the Opportunities of Brexit

The old adage – “the way to someone’s heart is through their stomach” - has never been more pertinent to global security. With the world’s population now exceeding 7.2 billion (an awful lot of stomachs to fill) we require a mind-boggling amount of food. In fact, farmers will need to grow as much food in the next fifty years as they did in the last 10,000 years combined. And at a time when one in eight people on the planet is already chronically malnourished, this is clearly an issue that isn’t going to be resolved purely by traditional production methods. Resources are particularly limited in high economic-growth regions such as China, a country that has to feed 22% of the world’s population but which is endowed with only 7% of the planet’s cultivable land. With so many increasingly vociferous middle-class mouths to feed, it is unsurprising that food security is rapidly becoming the most contentious issue in Chinese politics.

Inspired in part by India’s “Green Revolution”, China has been keen to expand their area of influence in the agrichemical sector, and have been investing heavily in their own research into genetically modified technologies. As with many aspects of China’s economy, however, their GM industry is dominated by state-owned companies, reflecting the government’s political objective of securing domestic food supply through improving agricultural productivity. 

What would it be like if the government really did run the economy?

It's very difficult indeed for us to map out exactly how it would all turn out if the government really were to run the economy in detail. Thus we need to try and find a comparator, somewhere that has two economic systems and we can observe the different outcomes.

We can of course think of the grand experiment that was the 20th century. Those places that had state socialism ran a race against those that used markets and the state socialism lost. But of course no one calls for such any more - at least we are continually assured.

But there are people calling for a democratic economy - that is, one where everything is decided through voting on committees. Others call for the bureaucratic economy, where the committees decide and there're even those absurdists who demand a Courageous State, where politicians decide each detail.

What we would like to find therefore is somewhere which has something like our market mix and right next to it something more like that state run and controlled economy so we can observe the different outcomes. Fortunately we have this - the United States. Government, planning, bureaucratic control, once again lose

Imagine if the government were responsible for looking after your best interests. All of your assets must be managed by bureaucrats on your behalf. A special bureau is even set up to oversee your affairs. Every important decision you make requires approval, and every approval comes with a mountain of regulations.

How well would this work? Just ask Native Americans.

The federal government is responsible for managing Indian affairs for the benefit of all Indians. But by all accounts the government has failed to live up to this responsibility. As a result, Native American reservations are among the poorest communities in the United States.

Hmm, perhaps government isn't the way to run life and the economy then?
