“For the proposition that supply creates its own demand, I shall
substitute the proposition that expenditure creates its own income”
JM Keynes Collected Writings, Volume XXIX, p. 81
G20 Finance Ministers met in Huangzhou, China recently and refused appeals from both the IMF and the OECD for “urgent collective policy action” that focussed “fiscal policies on investment-led spending”. Instead the world’s finance ministers concluded that “it's every country for themselves”.
Keynes’s simple proposition is compelling: that expenditure will expand national (and international) income (including tax income) and thereby reduce the deficit. But it is a proposition that is anathema to OECD politicians, their friends in the finance sector and their advisers. Instead they adhere stubbornly to the antiquated classical economics embodied in Say’s Law.
Rather than relying on expenditure or investment, the British 2010-2015 Coalition government and then the 2015 Conservative government placed excessive reliance on monetary policy to revive aggregate demand for goods and services. The consequences were predictable. Loose monetary policy enriched those that owned assets – stocks and shares, bonds or property. The evidence of this grotesque enrichment is clearest in London. According to the FT (20 Feb 2016) the owners of South Kensington residential properties have seen “substantial capital appreciation – 45 % over the past five years and a remarkable 155% since 2006.” And as the Bank of England concluded back in 2012 in its paper on the Distributional Effects of Asset Purchases” (i.e. QE)
“the benefits from these wealth effects will accrue to those households holding most financial assets.”
By contrast fiscal consolidation (austerity) has since 2010 hurt those that do not own assets – i.e. those who live by hand or by brain, or who are dependent on welfare, and do not benefit from the rent generated by the ownership of assets. Now, the British government is set to impose the largest fiscal consolidation of all OECD countries . Worryingly, it proposes to do so at a time of global economic and financial fragility.
But the British government has not been alone in pursuing policies that enrich the already rich, while contracting wider economic activity. Over-reliance on central bankers and monetary policy, coupled with deflationary and contractionary fiscal policy is the cause both of ongoing weakness in OECD countries and of the slow but inexorable decline in world trade since 2011.
We need to recall that global fiscal consolidation was actively promoted by the OECD back in 2011. OECD economists set a target of a debt-to-GDP ratio equal to 60% of GDP by 2025 in their 2011 paper: “Fiscal consolidation: targets, plans and measures.” In a paragraph headed, 'Renewed growth will not be enough to stabilise debt', the OECD economists argued: 
“Economic growth may reduce some of the deficit, but will not be sufficient to stop mounting debt levels in many countries. The OECD has estimated the fiscal surpluses required from 2011 onwards to stabilise debt-to-GDP ratios by 2025. The consolidation requirements are substantial but vary considerably. According to this model, Japan, for example, will require a primary surplus of 3.7% of GDP in 2025 to stabilise the debt ratio. Assuming a deficit of 5.5% of GDP in 2010, Japan therefore needs a consolidation of 9.2% of potential GDP by 2025.
Using the same calculation, tightening by more than 8% of GDP is called for in the United States, with Ireland, Poland, Portugal, the Slovak Republic and the United Kingdom all requiring consolidation of 5-7 percentage points of GDP by 2025. In the OECD area, an improvement of more than 5% of GDP from the current fiscal position is required to stabilise the debt-to-GDP ratio.” (My emphasis)
What followed from the launch of fiscal consolidation targets in 2011 was wholly predictable. According to the Trade and Development Report of 2015 , between 2012 and 2014, the rate of growth of world trade slowed to between 2 and 2.6 per cent – growth rates significantly below the average annual rate of 7.2 per cent during the 2003-2007 pre-crisis period. In 2014 world merchandise trade at current prices grew at even lower rates (only 0.3 per cent) due to the significant fall in prices of major commodities.
This slow-down in trade was then exacerbated by the October, 2013 decision of the US’s Federal Reserve to end “life support” for the US finance sector and the wider economy, and to “taper” its purchase of assets (bond-buying) under its programme of Quantitative Easing. This led as expected, to a further weakening of the US economy, which in turn lowered demand for commodities from emerging markets, most notably, China.
The Fed’s taper began in December 2013. Its decision was followed almost immediately by a steep fall in emerging market currencies and stock markets in mid-January, 2014. These in turn were followed by dramatic and ongoing falls in commodity prices, including oil. The ending of ‘life support’ led to a fall in US and then OECD-wide demand for goods and services from these emerging markets. A consequence was the build-up of gluts of steel, cement, autos, rubber and other goods in China and other emerging markets. These gluts in turn deflated prices at a global level, and led to turmoil and growing trade imbalances in emerging markets. Policy-makers like the UK Chancellor, and commentators in for example, the Financial Times were slow to react to the worldwide fall in prices, attributing the falls to the oil price alone, and calling the phenomenon “good deflation.”
As “deflationary tides (lap) at the shores of countries around the world”  members of the economic establishment are belatedly waking up to the huge threat posed by this relatively unknown, and widely misunderstood phenomenon.
Deflationary policies gradually, but inexorably increase the value of money (credit or debt) above the present value of goods and services – which is why they are favoured by the financial services sector. As Keynes once famously argued (in his Tract on Monetary Reform (1923)):
“Deflation, as we have already seen, involves a transference of wealth from the rest of the community to the rentier class and to all holders of titles to money; just as inflation involves the opposite. In particular it involves a transference from all borrowers, that is to say from traders, manufacturers, and farmers to lenders, from the active to the inactive.”
In some parts of the financial establishment complacency has now been replaced by scarcely contained panic, as expressed for example by the Washington-based Institute for International Finance - the elite club for private bankers:
“Vulnerabilities make the global economy highly fragile, susceptible to being tipped into synchronized downturn.” 
The OECD, the Economist, the Financial Times, the IMF and other cheerleaders for monetary radicalism and fiscal consolidation have recently made dramatic U-turns and expressed visible alarm at the threat posed by global deflationary pressures, high levels of private debt (including in China) weak economic growth, the risk of banking failures (as the cost of debt and therefore default risks rise relative to the deflation of prices and incomes); and of the possibility of renewed financial crises and a “synchronised downturn”.
The IMF argues :
“near-term fiscal policy should be more supportive where appropriate and provided there is fiscal space, especially through investment that boosts both the demand and the supply potential of the economy.” At the same time the global financial and economic establishment – as represented by the IMF, the OECD and even the Economist - belatedly acknowledge that central bankers have exhausted the monetary policy tools (or “ammo”) at their disposal.
However, G20 finance ministers at their recent Summit in Hangzhou, China, were far less concerned. Indeed they allowed the UK Chancellor to hijack their final statement with a reference to Britain’s domestic problems over a forthcoming referendum. For those who could find it buried under the Brexit news coverage, the G20 communiqué was upbeat about the economic outlook, and divided over the need for co-ordination or collective action. They recognised the “challenges” facing the global economy, but nevertheless
“expect activity to continue to expand at a moderate pace in most advanced economies, (while) growth in key emerging market economies remains strong."
Such shrug-of-the-shoulders complacency is worrying, given the divisions that exist at global level. As Bloomberg reported:
“With the U.K. mulling spending cuts, Japan planning a sales tax increase, Germany’s finance minister warning debt-funded growth just leads to “zombifying” economies, and the U.S. constrained by a lame duck president and Republican-controlled Congress, it may fall to China to ratchet up the fiscal firepower.” (Bloomberg, 27 February, 2016.)
However China faces big challenges too. It is a nation with large numbers of poor people, and with levels of private debt that exceed US debt levels as a share of GDP. China cannot therefore be expected – to once again - singled-handedly drive the recovery of much richer, austerity-fixated OECD economies.
So while the international club of bankers is worried that “vulnerabilities make the global economy highly fragile, and susceptible to being tipped into synchronized downturn”  - G20 finance ministers refused to bury both their differences, and their obsession with austerity - to synchronise their response to this “highly fragile” global economy.
Their confidence in austerity is surely misplaced. For as Mark Carney, governor of the Bank of England noted recently, the British Chancellor expects “the largest fiscal consolidation in the OECD” to lead to a decline in the structural deficit of around 1 percentage point a year over the next four years. This after the deficit has only fallen by 1/3 of a percentage point on average over the last three years - despite a massive fire sale of UK taxpayer-owned assets.
So, expect very little global leadership or co-ordination from our elected politicians. They remain captured by contractionary, deflationary economic theory and policies; policies which serve the interests of the rentier – the titleholders of money. Policies which threaten to tip the global economy once more into a “synchronised downturn”.
