How Labour should deal with the Fiscal Responsibility Act

By Michael Burke

Jeremy Corbyn and John McDonnell are frequently in advance of many of their supporters on economic matters, including their supporters in academia and economic commentators. They are correct to argue against permanent budget deficits and in favour of the central role of public investment as the path out of the crisis, identify People’s Quantitative Easing as a useful policy tool, and to question the ‘independence’ of the Bank of England. They have faced unwarranted and confused criticism on all of these from some on ‘the left’.

The recent indicators point to a slower pace of economic activity and the Tory government is about to embark on Austerity Mark II, in nominal terms exactly the same level of cuts and tax increases as the £37 billion George Osborne announced in 2010. As the Tories have little popularity (the second lowest popular share of the vote for any government) it has been necessary for this project that there is a pretence that this not a return to austerity, after the boost to consumption that helped the Tories get re-elected. So, there was the fiction that recently there was a ‘One Nation’ Tory Budget, that Osborne was ‘stealing Labour’s ideas’ and similar nonsense.

Politically it is crucial for the Tories that there is no opposition to the latest version of cuts, as this would show the blantant falsity of the claim that the Tories have a commanding parliamentary majority and that There Is No Alternative. This necessity explains why the other Labour leadership candidates were so wrong to give the Tories a free pass on welfare cuts.

However the election of Jeremy Corbyn and the appointment of John McDonnell as Shadow Chancellor changes the previous situation in which Labour did not in fact challenge the Tories' central economic policies. Now the Tory tactic is to set a series of political traps for the new team in the hope of detaching them from either, or both, the majority of the population or their base of supporters. This is taking place primarily on the area of foreign affairs and the military. But on the economic front this will be the introduction of an amendment to the Fiscal Responsibility Act. This proposed Act precludes borrowing in normal circumstances/over the course of the cycle not only for current government expenditure but also for investment. It also commits future governments to run budget surpluses when the economy is growing, to be overseen by the Office for Budget Responsibility.

Labour’s response

Initially, George Osborne hoped that by announcing the new law and holding it over to the autumn that it would dominate the Labour leadership campaign. That has failed spectacularly. Instead it is possible to turn the tables on Osborne and use the debate and vote to set out clear differences with him.

To achieve this it is necessary to approach these questions soberly and intelligently. To paraphrase a remark by Trotsky, the appropriate economic policy is not at all automatically derived from the policies of George Osborne, simply bearing only the opposite sign to him – this would make every madcap pundit an economics guru. It is necessary for Labour to put forward a positive economic policy based on a correct economic theory.

Labour should formulate its own policy and pose that sharply in contrast Osborne’s. It must be based on a clear understanding of the difference between consumption and investment. Investment is the chief motor of economic growth, with the latter in turn being the chief determinant of the population’s living standard. Therefore the way to ‘grow the economy out of the crisis’, as Jeremy Corbyn and John McDonnell have correctly put it, is to increase the economy’s level of investment. As the private sector has failed to do this the state should step in. This should be expressed in a policy to increase state investment, and to create National Investment Bank – which should finance both state and private investment.

The key question is where the savings equivalent to such investment should come from, and this in turn relates to the current expenditure in the budget. Current expenditure can be financed in one of two fundamental says. It can be financed by borrowing, but in that case this reduces the proportion of the economy devoted to savings/investment, which is undesirable as it will slow economic growth and therefore the increase in living standards. Or consumption can be financed by taxation, in which case it merely means privately financed consumption is being replaced by government financed consumption (either government final expenditure or transfer payments) in which case the level of investment is not being reduced and growth will not be reduced.

It therefore follows that for a coherent and sustainable policy current government expenditure should be financed out of taxation, in particular on higher incomes and luxury consumption, and not out of borrowing.

Expressed in terms of budget deficits and borrowing his means that the aim should be for a balanced current budget over the business cycle, but reserving the right to borrow for state investment. This is the correct position expressed by John McDonnell. This therefore means that an amendment to Osborne’s Bill expressing that position, of no deficit over the cycle for current expenditure but permitting borrowing for investment, should be moved by Labour. This will establish its position clearly.

But, in the likelihood an amendment of this type were to fall, although some other parties may vote for it, then Labour should vote against the entire bill – as it excludes borrowing for investment. (In fact the level of state borrowing for investment currently should be considerable, up approximately 3-5% of GDP). Labour should explain its position of voting against the bill as a whole because of the defeat of its amendment.

In this way, Labour’s approach would be very clear. It is not in favour of public borrowing to fund current expenditure and is in favour of borrowing to fund investment. As a balanced budget law does not allow that investment, Labour would be opposed to the Tory policy.

Labour should not support the Bill without this amendment as this would preclude borrowing to invest and leave the economy at the mercy of a private sector which has achieved only chronic under-investment. Neither should it simply oppose the Bill without offering an alternative, especially not on the spurious grounds that any public sector surplus should be ruled out because it ‘obliges the private sector to run a deficit’. Sometimes the private sector, or at least the business component should be obliged to run down its savings, if it is hoarding cash and refusing to invest. Many countries accumulate budget surpluses in their sovereign wealth funds, to be used for investment at a later date. This is what should have occurred with the windfall of North Sea oil, rather than wasting it on consumption in the ‘Lawson Boom.’

In taking a clearly different approach, Labour's new leadership will be able to demonstrate it has an entirely different policy to the Tories based on increasing investment to increase prosperity.

The debate on 'deficit spending': The framework for Corbynomics

By Michael Burke
There is a debate among anti-austerity economists and supporters of the Jeremy Corbyn leadership of the Labour Party on balanced budgets and related matters. The debate was prompted by Shadow Chancellor John McDonnell’s commitment to eliminating the budget deficit and was sparked into life by this SEB piece, The need to clarify the left on budget deficits- confusions of so-called ‘Keyenesianism’. It was met with this reply from PRIME economics, ‘Living within our means’: deficits and the business cycle.
The debate relates to fundamental issues of economics and economic policy. It leads to what policy framework a radical, anti-austerity party (or government) should adopt. In the course of a constructive debate we should aim to arrive at some greater clarity on this important issue.
The debate
The original SEB piece began with the argument that the main factor accounting for growth is investment. This has long been the position in classical economics from Adam Smith, who called it an ‘increase in stock’, to Marx, who used the term ‘development of the productive forces’. Keynes pointed out that the ‘General Theory’ was primarily concerned with how to regulate the investment function in order to achieve growth and prevent slumps*. Modern usage speaks of an ‘increase in productive capacity’.  However, the logic of this classic position has now been demonstrated by the highest point of modern econometric analysis, most especially through Vu Minh Khuong’s masterly study The Dynamics of Economic Growth .
All output requires inputs. Consumption is not an input and therefore cannot lead economic growth. All economic activity depends first on production (of a good or service).  It is not possible to consume that which does not already exist, either through nature’s abundance, or through the production process.
The decisive inputs for output are the level of fixed investment and the amount and quality of labour. Vu Minh Khuong’s study shows that, taken together these account for about 90% of all growth in the advanced industrialised countries, with fixed investment playing the predominant role (57% of all growth in the advanced economies).
Consumption cannot logically be input to growth. Consumption takes place only after the production process is complete, and is highly dependent for its own growth on the growth of output. It has a dependent, subordinate role in relation to output.
There are also only two ultimate destinations for output. It can either be consumed or invested. Since investment is the sole factor of these two which can raise the level of output, it follows that the greater proportion of output devoted to investment, the greater the potential growth of that output. The opposite also applies. The greater proportion of output devoted to consumption, the lower the potential growth of output. There is no such thing as ‘consumption-led growth’ (or its near cousin, ‘wage-led growth’ as wages too are a consequence of output, and the struggle between classes over its distribution).
A farmer’s crop in one year is ten bags of wheat. If she and her family consume all ten bags, there is no seed to sow for next year’s harvest. If she retains two bags to sow next year the crop will be the same. But if she can reserve 3 bags to so next year the crop will be 50% bigger, all other things being equal. By increasing the proportion of output devoted to investment, total output rises in the following year and so can the level of consumption. The increasing complexity of economic activity does not alter these fundamental relationships between investment, growth in output and consumption.
This relates to the debate on balancing the budget. If a radical, anti-austerity government simply borrows or creates money to fund consumption, it will provide no boost to long-term growth. This is merely a stimulus to spending or consumption. This may be needed when consumption has fallen dramatically but cannot be a feature of a medium-term economic policy.  If on the other hand, the same government borrows to invest in the productive capacity of the economy then the economy is capable of sustainable expansion.  This in turn can lead to economic growth and the growth in consumption. Therefore such a government or economic policy framework, which we can call Corbynomics, should aim at increasing the level of borrowing for investment and aim at eliminating borrowing for consumption in favour of borrowing for investment.
Unfortunately, the PRIME piece does not deal with this substance of the original argument. Instead, there is agreement that there is only consumption or investment, and no logically separate category of ‘government’. It agrees on the need for public investment.  It also agrees that there can be money creation to fund public spending.
But it is hopelessly confused in treating the central argument. This is that there is only consumption or investment, and of these two only the latter can contribute to growth. Instead, it accuses the original piece of containing:
‘the classical economists’ error of assuming there is a fixed amount of money which if used for purpose (a) cannot be used for purpose (b)’.
This is false and somewhat foolish. Consumption and investment are different functions. ‘Money’ or more accurately output, cannot be used for both functions simultaneously.  Money is a medium of exchange used to purchase a good or service, and this can only be for consumption or investment. (Money as capital can also be, and frequently is hoarded. This is the situation currently and which is why the state must lead an investment recovery.) Furthermore, the proportions between consumption and investment are decisive for growth.
If Nominal GDP (Y ) is 100, and Consumption  (C) is 85 and Investment (I) is 15.
The ratio between the two is approximately 5.5 : 1 (This is the position in the US economy currently. In the British economy it is close to 6.5 : 1).
If Y remains at 100 but C is increased to 90, then I must fall to 10. Contrary to the assertion of the PRIME article the two must sum to 100. But the ratio between them has adversely altered in terms of subsequent growth.
The PRIME piece may be confused between proportions and levels. This is not clear but is implied in the digression on the desirability of public services such as the NHS, education and so on.  Neither SEB nor, more importantly, John McDonnell favours cuts to spending in these areas, indeed both would seek to raise them. But the PRIME piece seems to suggest that this is what is stake in the debate and this is a confusion of its own.
To clear up this confusion: C cannot add to Y. This is because, if C = Y, then I must equal zero. As a consequence Y cannot grow. Nor can C grow, because it is based on Y and follows it. But if Y is 100 and C is 75 and I is 25, then the ratio between the two changes from 4.5 or 5 to 3. And, all other things being equal  the growth in Y will increase in following years by approximately 2%, from which it would be possible to increase C and I.
No-one in this debate wants government spending on public goods and services to decline, or the pay that is necessary to provide them nor the entitlements to social protection. That is the austerity policy.
But it is only possible to launch a sustainable increase in public services if there is economic growth, and this depends on investment. The principal policy aim should instead be aimed at driving up I at the optimal sustainable rate. This is the main factor (along with improving the quality of labour via education and training) which can lead to a rise in average living standards. Therefore the requirement to increase I is the basis for all serious discussion on People’s QE, government borrowing, taxation, wasteful spending such as Trident, and so on.  The determining role of investment in creating growth and prosperity explains the role and importance of borrowing to invest.
It is not possible to shop your way to riches. Neither is it possible to borrow your way to fund consumption. This is effectively what has been encouraged in the Western economies over a prolonged period. It has led to economic slump and stagnation.
As for the current budget deficit, this was £66 billion in 2014 while the revenue form Corporation Tax was £42 billion. It would be possible, for example, to have a graduated rise in this tax rate alone to halve the current budget, while still leaving the rate below that of the US, Germany, Japan and other industrialised countries.
But the main driver of the decline in the current budget would be growth itself, which, as the PRIME piece agrees, would generate tax revenues and lower government outlays. The disagreement lies in identifying how that growth is to be generated.

Crisis hasn’t gone away. Corbynomics will be increasingly necessary

By Michael Burke

One of the most widely repeated falsehoods about the British economy is the assertion that it is growing strongly and that the crisis is over. This is not borne out by even a perfunctory economic analysis but it serves a political purpose. In the first instance the assertion was important in order to blunt any criticism of renewed Tory austerity policies, which will begin again earnest with the Comprehensive Spending Review in December. Now that Jeremy Corbyn has won the leadership of the Labour Party the same falsehood is pressed into slightly different service- with the idea that his policies represent a threat to the current recovery, or are at least unnecessary.

In reality, the extremely limited upturn in output is already giving way to renewed weakness. UK industrial production and manufacturing fell in July. Monthly data can be erratic but this is the second consecutive fall for industrial production and manufacturing peaked in March, shown in Fig. 1 below.
Fig.1 Industrial production and manufacturing index from April 2013 to July 2015
Source: ONS
This is not the boom that is repeatedly claimed. The recovery to date is primarily based on consumption not investment. Since the beginning of the recession to the 2nd quarter of 2015 consumption has risen by £70bn, a modest rise of 5%. But investment has risen by just £4bn, a cumulative rise of just 1.3% over 7 years, less than 0.2% annually.

In terms of output and investment, the notion of a boom amid austerity is entirely misplaced. There is only stagnation. In fact, the levels of industrial production and manufacturing are effectively unchanged since the Coalition took office in May 2010, despite inheriting a mild recovery. In May 2010 the index levels of industrial production and manufacturing were 100.2 and 97.6 respectively. In the most recent data they were 99.2 and 100.6. The trends in output are shown in Fig.2 below. They clearly show that under austerity production has stagnated.
Fig.2 Output trends from January 2008 to July 2015
Far from a boom the current economic situation is best characterised as stagnation. In one form or another this also characterises the Western economies as a whole. Since the recession began in the OECD as a whole, the average annual level of GDP growth has been under 1%. Consumption has risen by US$2.5 trillion over that time. But Gross Fixed Capital Formation has declined by $200bn over the same period.

For the British economy, this continued reliance on consumption holds a particular threat. The relative weakness of investment and hence the relative weakness of productivity is a chronic one in Britain. The current crisis has deepened these severe long-term problems. Output has fallen back to levels last seen in the 1980s, as shown in Fig.3 below. This represents a combination of both the long-term weakness of manufacturing and the decline in the output of North sea oil, a financial windfall that has been almost entirely wasted.  
Fig. 3 Industrial production over the long-term
As it is not possible to consume that which is not already in existence, consumption must follow output. It cannot lead it. As the output of the British economy is experiencing both a structural and a cyclical decline, its increased consumption has been funded by its surplus on ‘financial services’, the money British banks extort from the rest of the world, and on increasing indebtedness.

As the revenue from financial services has now also gone into decline, so the resources for consuming without producing are increasingly through borrowing. The broadest measure of Britain’s overseas borrowing requirement is the balance on the current account. The current account includes both the trade balance and the balance on all current payments , primarily company dividends and interest payments by borrowers. Any deficit on the total current account must be met by increased borrowing from overseas (or asset sales to overseas). The latest 3 quarters have seen the worst current account deficits as a proportion of GDP since records began, as shown in Fig.4 below.  
Fig.4 Current account blance as a proportion lof GDP

The financing of this deficit depends on the willingness of overseas investors to buy UK assets. It is impossible to predict the precise point or catalyst for them to stop doing so. But what is known is that the British economy has faced a number ‘balance of payments’ crises before when the relative level of overseas borrowing was far lower. One possible way of reducing the current account deficit is to impose higher savings rates on the household sector, raising the taxes and reducing the wlefare transfers to them from government, which is one effect of renewed austerity. But even austerity Mark II will be unable to close the current account gap of this magnitude entirely.

Therefore the British economy is facing a series of interrelated crises, of production, slow growth and unsustainable borrowing. In reality they are key products of a single crisis- the crisis of weak investment. Contrary to the Tory propagandists, the supporters of austerity and their apologists, the crisis of the British economy has not at all gone away. As a result Corbynonics, a state-led increase in investment, is vital to end it.

The need to clarify the left on budget deficits - confusions of so called 'Keynesianism'

By John Ross
John McDonnell, the new Shadow Chancellor, has created something of a stir by his firm opposition to budget deficits to cover current expenditure – writing ‘let me make it absolutely clear that Labour under Jeremy Corbyn is committed to eliminating the deficit and creating an economy in which we live within our means.’ The so called ‘Keynesian’ left has attempted to make a point of defending budget deficits, presenting this as a hallmark of the left. These latter views are politically damaging because they are economically false. Neither do they derive from Keynes but from the confused views of academic pro-capitalist economics. John McDonnell is entirely correct on this point to oppose borrowing to cover current expenditure over the course of the business cycle.

The following article, originally published as ‘A damaging confusion in Western economics books - which followers of Keynes and Marx should correct’ deals with this issue from a fundamental economic point of view. A more comprehensive treatment of the issue, presented in a less technical fashion, can be found in my article ‘Deng Xiaoping and John Maynard Keynes’.

Hopefully John McDonnell’s firm stance on the budget deficit will help the left to adopt the positions of Keynes and Marx and abandon the confused ideas on budget deficits that were wrongly presented under the name of ‘Keynesianism’.

* * *

Economics textbooks, particularly when discussing Keynes, frequently contain an elementary economic confusion - it should be made explicit this is a confusion in the textbooks and is not stated by Keynes. A typical example may be taken as Mankiw’s Principles of Economics, but numerous other examples could be cited as the confusion is widespread.1 This elementary economic  confusion is expressed in the following formula

Y = C + I + G + NX

In this widely used formulation Y = GDP, C is private consumption, I is private investment, G is government spending, and NX is net exports. For a closed economy, which can be considered here as trade is not relevant to the issues analysed, this becomes.

Y = C + I + G

From this it is typically argued that if there is a shortfall in private consumption C, private investment I, or both, then this can, or should, be compensated for by an increase in government spending G. This allegedly constitutes a ‘Keynesian’ policy. The fundamental confusion is that there exists no category ‘government spending’ G which is neither consumption nor investment – government spending is necessarily used for either investment or consumption. In short the correct formula is expressed as

Y = Cp + Cg + Ip + Ig

Where Cp is private consumption, Cg is government consumption, Ip is private investment and Ig is government investment.

Keynes himself is clear on the distinction writing:
‘loan expenditure’ is a convenient expression for the net borrowing of public authorities on all accounts, whether on capital account or to meet a budgetary deficit. The one form of loan expenditure operates by increasing investment and the other by increasing the propensity to consume.2

This formula clearly distinguishes Cg and Ig as indicated above.

For Marxists it should be noted that this distinction is also made clear in Marx’s categorisation of the economy into Department I (investment goods and services) and Department II (consumption goods and services).

The attempt in economics textbooks to introduce a third category G which is neither used for consumption nor investment is a piece of economic nonsense which should be stopped.

A key reason the lack of clarity created by introducing the confused term G is practically economically significant is the consequence for the structure of the economy when is there is unspent private saving, including non-invested company saving – i.e. private saving is not being transformed into private investment, and the government steps in to maintain demand. There are then two possibilities.
  • If non-invested private saving is used by the government for investment, that is Ig increases, there is no change in the economy’s overall level of investment – private investment is simply replaced by government investment.
  • If, however, the non-invested private savings is instead used by the government to fund consumption, that is Cg increases, then the percentage of consumption in the economy rises and the percentage of investment falls.
The use of an economically confused term G therefore obscures the choice being made for the economy’s overall investment level by whether there is an increase in government investment Ig or an increase in government consumption Cg.

The practical significance of this confusion is that modern econometrics shows that capital investment is the quantitatively most important factor in economic growth. Therefore reducing the proportion of the economy used for investment, other things being equal, will reduce the economic growth rate.

Both economic economic theory and practical results show that in a capitalist economy, not necessarily an economy such as China's, there is greater resistance to government spending on investment than on consumption - as state investment involves an incursion into the means of production, which in a capitalist economy by definition must be predominantly privately owned. This theoretical point is confirmed by the fact that state expenditure on consumption has historically risen as a proportion of GDP in most capitalist economies since the economic period following World War II while state expenditure on investment has in general fallen in the same period.

The acceptance of government expansion of consumption, but opposition to government investment, therefore has the consequence that when so called ‘Keynesian’ methods of running government budget deficits are used, and G rises, what in practice happens is that Cg rises but Ig does not. As the government is transferring non-invested private savings into consumption such so called ‘Keynesian’ intervention therefore has the effect of reducing the economy’s investment level – and therefore reducing the economic growth rate. This process is concealed by using the confused term G instead of its proper components Cg and Ig .

However, as already noted, it should be made clear that this confusion is in textbooks and not in Keynes himself. But followers of Keynes should point out this elementary and damaging confusion contained in many economic textbooks.

Corbynomics and crashes: investment versus speculation

By Michael Burke

Words matter. But in economic discussion as elsewhere they are frequently abused. In economic commentary one of the most frequent falsehoods is to describe speculative activity as investment. Stock market ‘investors’ are in fact engaged in speculative activity. There is no value created by this speculation. The claim made by its apologists that it provides for the efficient allocation of capital to productive enterprises is laughably untrue in light of both recent events and long-run history. In fact, a vast number of studies show that that there is an inverse correlation between the growth rate of an economy and the returns to shareholders in stock market-listed companies.

The chart below is just one example of these studies, Fig. 1. The research from the London Business School and Credit Suisse shows the long-run relationship between real stock market returns and per capital GDP growth. The better the stock market performance, the worse the growth in real GDP per capita. The two variables are inversely correlated.

The Economist found this result ‘puzzling’. But it corresponds to economic theory. The greater the proportion of capital that is diverted towards speculation and away from productive investment, the slower the growth rate will be, and the slower the growth in prosperity (per capita GDP).

Fig.1 Stock market returns and per capita GDP growth

This is exactly what has been happening in all the Western economies over a prolonged period. SEB has previously identified a declining proportion of Western firms’ profits devoted to investment. The uninvested portion of this capital does not disappear. Instead, it is held as cash in banks and the banks themselves use this to fund speculation and share buybacks by companies (which simply omits the banks as intermediaries in the speculation). The effects of this are so marked that some analysts believe ‘financialisation’ is the cause of the current crisis, when instead it is an extreme symptom of the decline in investment and the consequent growth of speculative activity.

Stock market crashes

It is now customary in the Western financial press to routinely ascribe all aspects of the Great Stagnation to some failing in China. So, China’s fractional currency devaluation has been identified as the culprit of the recent stock market plunges, even though the 3% devaluation of the Chinese RMB followed a 55% of the Japanese yen and a 27% decline in the Euro.

The claim that the crashes were caused by China’s currency move has no factual basis. Fig.2 below shows the closing level of the main US stock market index in August. The S&P 500 rose from 2,083 to 2,102 in the 4 days after the RMB’s 3.2% devaluation which finished on August 13 (first arrow).

On August 19 the Federal Open Markets Committee (FOMC) of the US central bank released the minutes of its most recent meeting (second arrow), which was widely interpreted as indicating a strong likelihood that interest rates would be increased in September. The prior closing level for the S&P500 was 2,097 and it fell sharply thereafter. Following speeches by a number of governors of the US Federal reserve (who vote on the FOMC) questioned the need for an increase in rates, and the market has recovered in response. Yet other speeches pointing once more to a rate rise led to stock market falls once more, and so on.

Fig.2 S&P500 Index
But this uncertainty over US rate increases is only the proximate cause of the crashes. This sharp fall is a stock market verdict that it cannot easily absorb higher US interest rates. The current valuations for the stock market are based on official short-term interest rates of 0.25% and a dividend yield on S&P500 stocks of 2.24%. Even if rates were only doubled to 0.5% the level of the stock market becomes much less attactive. If rates were to rise towards 2%, the risky stock market’s dividend yield looks extemely unattractive compared to risk-free short-term interest rates.

There is a spearate matter that the US economy does not look robust enough to absorb any significantly higher interest rates, but this hardly concerns stock market speculators. Fig. 3 below shows the pace of growth in US industrial production versus the same month a year ago. Production has slowed for a year and is down to a snail’s pace in the last 3 months, averaging less than 1.4% from the same period a year ago. The latest data show that the US economy is experiencing only modest growth, with GDP in the 2nd quarter just 2.6% higher than a year ago.

Fig.3 Growth In US Industrial Production

Despite the widespread hype about the British economy, the equivalent data on industrial production is growth of 1.5% for the latest 3 months compared to a year ago. For the Eurozone it is 1.2%. In China, industrial production has grown by 6.3% in the latest 3 months compared to the same period a year ago.

Corbynomics and crashes

Since 2010 the major central banks of the US, Japan, and the Eurozone have created US$4.5 trillion, Yen 200 trillion and €1.1 trillion in their respective Quantitative Easing programmes. The Bank of England has added £375bn of its own. Over the same period short-term official interest rates have been at or close to zero. Long-term interest rates have also plummeted. This has not led to a revival of investment in the advanced industrialised economies. After the short-lived stimulus in some Western economies to end the 2008-2009 slump, total fixed investment (Gross Fixed Capital Formation) has slowed to a crawl in the OECD as a whole, as shown in Fig.4 below.

Fig. 4 OECD GFCF, % change 1996 to 2013

Yet over the same period the main stock market indices in the OECD economies have soared. The stock markets and real GDP are inversely correlated. The S&P500 index has effectively doubled since 2011. The Eurofirst 300 has risen by 55%, the Nikkei 225 in Japan has risen by 125% (boosted by currency devaluation) and the FTSE100 has risen by 25% (a poorer performance held back by the predominance of weak international oil and mining stocks). Data for 2014 is not yet available but the total cumulative increased on OECD GFCF from 2011 may not have reached 10%.

Corbynomics is the policy of attempting to address an investment crisis with an increase in investment. Its critics repeatedly claim that this policy will cause financial turmoil. In light of recent events this assertion ought to cause a wry smile. At the very least, the most powerful central banks in the world have to reassess their intentions on policy simply because of the wild gyrations in the stock markets. These have been accompanied by further large movements in global currency exchange rates.

The reason stock markets are so febrile, and policy so easily blown off course is that a bubble is being created in financial assets because of the combination of monetary creation, ultra-low interest rates and weak investment. Capital that could be directed towards increasing the productive capacity of the economy is instead being used to finance speculation; the worst of both worlds. This policy has caused inflation in financial assets such stock markets, in house prices and (previously) in commodities prices. But continued economic stagnation means that deflation is now the greater risk in the OECD economies at the level of consumer prices.

Corbynomics addresses those risks because its aim is to raise the level of investment in the economy. By increasing the productive capacity of the economy through investment-led growth it overcomes the weakness of the economy. By redirecting the flow of capital from speculation towards investment, it deflates the speculative bubble. So, to take an obvious example, by building new homes it provides housing and employment while deflating the house price bubble.

The root of the objection to Corbynomics is the insistence that the private sector, private capital must be allowed to dominate the economy in its own interests. But the current Western economic model is a combination of shopping and speculation, leading to stagnation. Corbynomics is the antidote to these; prosperity through investment-led growth.
