Abstract
We believe that the main problem in European
economies post the GFC is lack of demand, which in turn is dampening productivity
and putting a lid on supply-side efforts. Macroeconomic policy can indeed
contribute to explain and solve the productivity puzzle, especially in the
absence of expansionary fiscal policies. We believe that government creation of
narrow money is a more appropriate tool for economic stimulus than QE; and that channeling such funds into research-intensive areas (high on human capital,
low on capital expenditures) has the highest potential to raise productivity in
the long term.
Introduction
This note is focused on the productivity puzzle of the UK. We will focus
on the residual of Solow’s model, TFP ≅ GDP/h worked. A recent Q-Bulletin by the BoE (Barnett, Batten, Chiu, Franklin, & SebastiĆ”-Barriel, 2014 Q2) acknowledges that
the:
- Labour
productivity growth in the United Kingdom has been particularly weak since the
start of the crisis.
- The
recent strength in hiring and modest pickup in productivity growth suggests
that spare capacity within firms is unlikely to explain much of the current
weakness.
- Factors
related to the nature of the financial crisis are likely to be having a
persistent impact on the level of productivity.
We completely agree with these
findings, and indeed believe that the circumstances around and reactions to the
Global Financial Crisis (GFC) bear explanatory power.
Backdrop
The financial industry
represented, and still does, a bigger proportion of the domestic economy in the
UK than it does in most other developed economies (at both sides of the
Atlantic). This obviously exacerbated the drop in economic activity during 2008-09.
Given the fortunes of the industry since then (increases in capital standards
and more stringent regulation), it’s not aided in the recovery either.
On the other hand, the UK
benefits from having its own currency. The GBP depreciated significantly against
all major currencies. Ceteris paribus
this improved competitiveness and foreign demand for British products and
services abroad, having a stimulative effect.
Unfortunately this demand was not
expected to come from the Euro-zone, the UK’s biggest trading partner. In 2010
Greece lost access to the markets, and it was followed by Portugal and Ireland.
The Troika was created to bridge these countries back to the financial markets,
implementing deep cuts that would enhance the supply-side and improve
competitiveness. The crisis heightened in 2011 and 2012 with the cuts that
ensued, pushing the Govs. of Spain and Italy towards insolvency.
The UK elected a new government
and also implemented austerity policies. (VAT rose from 17.5 pct to 20 pct; CGT
rose; there were welfare cuts, and Whitehall spending restraint. Fortunately
the cuts weren’t as deep as announced.) The rationale behind these was maybe
best articulated by the Chancellor, in the 2014 January WEF debate at Davos on
“The Future of Monetary
Policy” were Osborne shared stage with Summers, et al.
The UK Government perceived and responded
to the crisis very much as its stranded euro-zone neighbours. ‘Fiscal space’ was
perceived from an accounting point of view; and fiscal discipline was the only medicine
to fight off budget deficits and minimise the chances of recreating a Greek
tragedy.
This was in stark contrast to the
US and Japan, whose policymakers seemed to be more focused on the real economy.
Fiscal space was seen through the prism of idle econ-resources, especially
employment. Stimulating them would pay-off by itself by growing the tax-base. (And idea that Summers later developed with
DeLong (Summers & DeLong, 2012), highlighting that
by 2030 the Debt/GDP ratio would have been lower, had a bigger stimulus package
(deficit) been implemented. Data were run on the Fed’s model).
Future fiscal burdens were understood to be areas of
under-investment / under-maintenance in the economy, such as poorly maintained
infrastructure (which will require real assets in the future to be maintained.
Hence competing with other real projects).
We believe that the pro-cyclical and pro-austerity behaviour
of the UK Government, coupled with the depressed economy of the Eurozone are at the core
of the output and TFP loss from the pre-crisis trends.
Fiscal multipliers, Hysteresis, and the MMT
The best data we had on fiscal multipliers came from the natural
experiment post the Great Depression and WWII. Even if it was difficult to have
accurate measures of the fiscal multiplier (during recessions), most analyses
put it above 0.5. (Therefore discarding Ricardian
equivalence, and crowding-out counter-arguments.)
Today, it is clear that the level
is significantly above 1 (Blanchard & Leigh, 2013), and with the
zero-lower bound constraint we believe that the case for state intervention
mitigating the business cycle by counteracting economic downturns has been
reinforced. We further believe that
hysteresis, or inverse Say’s Law, is already detectable in the British economy:
Lack of demand is creating lack of supply.
This idea was introduced by DeLong and Summers: Fiscal Policy in a Depressed Economy (2012), and was further
contextualized by in Martin Wolf’s The
Shifts and the Shocks (2014). To note:
If companies don’t hold prospects of selling new products and services,
they will not develop the capabilities required to produce them. They are much
more likely to hoard cash and/or reward equity-holders. As companies invest
less in R&D and in building future capabilities, potential output
decreases. (And indeed, estimates of potential GDP have decreased throughout
the world since the GFC.)
We believe that economists solved this puzzle a long time ago. Fallacies
of composition, and specifically “The
paradox of thrift” are nothing new to Keynesians and Monetarists,
and its solutions are also easier than enhancing the supply-side.
In particular, for a country that
is leaking currency and demand (jobs) abroad through significant current
account deficits, it is very difficult to keep full employment. In fact, using the sectoral balance sheet: (I-S) + (G-T) + (X-M) = 0 (Fetherson, Godley & Cripps); full employment will
only be possible if either the private sector or the public sector
accommodates. Hence, if the trade deficit is higher than the contribution
(deficit) of the Government to the economy, the private sector must be
dissaving, leveraging up its portfolio.
“In the real world, there is no deposit multiplier mechanism that imposes quantitative constraints on banks’ ability to create money in this fashion. The main constraint is banks’ expectations concerning their profitability and solvency.”
Quote from (McLeay, Radia, & Thomas, 2014).
Since all new money is created as
a by-product of lending by banking
institutions, and it is not limited or constrained on deposits (Money
Multiplier from Monetary Base to M2 through RRR is not factual (McLeay, Radia, & Thomas, 2014), (Keister, Martin, & McAndrews, 2008)), the system is very
exposed to rising asset prices (especially real estate), creating too much
money and inducing the private sector to lever up its portfolio. Hence,
Quantitative Easing, which mainly stimulates demand by the ‘wealth effect’ of lower
rates at the end of the yield curve, just reinforces a trend that decreasing
interest rates initiated in the late 1970s.
If Governments insist on running balanced budgets throughout the cycle,
private debt has to grow faster than GDP for demand to be in line with
potential growth, and that’s a fundamentally destabilizing process (Turner, 2015).
Modern capitalism is biased
towards financing real estate financing rather than financing entrepreneurs,
SMEs, or PPP; which bodes badly for TFP. Additionally, as per Piketty, the nature of the distribution of income and
spending between capital and labour, and among labour (and across the world) is
not conducive to sustaining aggregate demand. (Higher savings rate among those
most able to support demand (Piketty, 2014))
Henceforth, for countries running
current account deficits and output gaps, such as the UK, we believe that
permanent money creation by the State (‘high powered’, or ‘narrow’ money) is
the best solution to sustain GDP –which could have second order effects on TFP
by simplifying the financial services industry and its money creation process.
Releasing unquantifiable amounts of human capital now absorbed by the Dodd-Frank
act and other regulations).
The Entrepreneurial State
If minimising output gaps is the low-hanging fruit in order to increase TFP,
to achieve meaningful and sustainable improvements of the standard of living
over time, we believe that further nudging by the state could have beneficial effects.
Besides smoothing the business cycle, we believe that the state should
play a role in minimising loss of applied knowledge and know-how. This builds
on Kenneth J. Arrow’s 1962 “Learning by Doing”. More recent work by Stiglitz & Greenwald (2014) suggests that market
economies alone typically do not produce and transmit knowledge efficiently. Adoption
and diffusion of knowledge takes place within institutions; and bigger firms
are more stable, and therefore better at preserving it than smaller.
Similarly, Mazzucato’s “The Entrepreneurial State” (2012) defends that
the state should regain a more central role in the economy, targeting areas of
the economy where the expected return on invested capital is higher. As an
example, the US Government through DARPA (at the DoD), ARPA-E (DoE) and NIH created
the foundations for the technologies behind the internet, the smartphones’ Artificial
Intelligence systems, and a myriad of other technologies in Tech, Green-Tech
and Healthcare, respectively.
The tech hubs born in California and Boston owe most of their successes
to these programs she argues; but additionally, there are important
externalities to these efforts in R&D: an important proportion of the
benefits are not purely economic and/or captured by the companies that develop
the technologies commercially. They benefit the environment, and/or communities
at large, sometimes at almost zero additional costs.
Conclusion
We believe that having a vibrant economy –growing at full capacity– underpinned by state institutions that aren’t scared to respond boldly and counter-cyclically to negative shocks, minimises loss of applied knowledge in the economy, and spurs investments in R&D and technology-enhancement projects.
Bigger corporations generally are more efficient than small:
productivity is correlated with organization size. But research activities are often
more fruitful and efficient at smaller institutions: more nimble and able to
adapt to the new technologies, apply them in new areas, and develop them
commercially.
We believe that the government should take a leading role in paving the
way an R&D intensive economy comprising both small and big companies; while
allowing some degree of market consolidation in mature industries where
innovation is difficult to come by.
The retail banking industry is an excellent case in point: the UK
Government has encouraged competition and an increase in the number of banks for
years. However, an improvement in the customer’s service is much more likely to
come from the Fintech startups recently originated in London than from
duplicating roles at corporate offices.
