“A growing body of empirical analyses […] demonstrate a strong positive link between the functioning of the financial system and long-run economic growth […] better developed financing systems ease external financing constraints facing firms”
Ross Levine: Finance and Growth: Theory and Evidence. Handbook of Economic Growth, 2005
Positive correlation between growth and:
• Liabilities of financial system ÷ GDP
• Bank credit to private enterprise ÷ GDP
• Turnover of equity markets ÷ market capitalisation

Banks take

from savers and
lend it to
borrowers
Banks lend money to ‘entrepreneurs/ businesses’, thus allocating funds between alternative investment projects

“With very few exceptions, the banks’ primary business
consisted of non- mortgage lending to companies in 1928
and 1970. By 2007 banks in most countries had turned
primarily into real estate lenders. The intermediation of
household savings for productive investment in the
business sector – the standard textbook role of the
financial sector – constitutes only a minor share of the
business of banking today.”
Oscar Jordá, Moritz Schularick and Alan Taylor

Debt overhang : the unavoidable choice?

Sustained low growth and low inflation – debt burdens never
decline
Debt erosion via ultra low
interest rates
But leads to new debt creation
Debt write-off, default and
restructuring
But has disruptive / depressive
effect

The Dilemma
Pre-crisis path of nominal GDP growth
Pre-crisis path of credit growth
4% - 5%
10% - 15%
If central banks had raised interest rates to slow credit growth…. this would presumably mean slower nominal GDP growth?
We seem to need Ċ ˃ NGḊP to ensure adequate NGḊP… but this produces financial instability and post-crisis recession
2% real growth
2% inflation

• But not because excessive money growth is a robust forward indicator of inflation
• But because excessive credit growth and level are forward indicators of crises, debt overhang, post crisis depression and deflation

- and creates debt overhang which traps us in slow growth
Most debt is not needed to drive growth
But what if maximum growth is not a desirable objective?

Growth in already rich countries: a possible position
21
• Growth in average per capita GDP has diminished potential to deliver human welfare
• Human ingenuity plus economic freedom will produce rise in productivity and thus growth
• Different forms of growth have different potential to increase human welfare
Maximising growth should not be the
objective
But economic freedom is valuable
in itself and will produce growth
Public policy needs to ensure that - the harmful impacts
of growth are minimised- The positive impacts
maximised

Growth and debt
Debt is an apparently low risk claim on future money income
Both the private credit creation system and the public political process can create “too much debt” relative to future prospective money income
This can leave economics stuck in a debt overhang trap
This problem is more likely to be severe if future money growth prospects
Are reduced for bad reasons
Should be reduced for good reasons
22
If maximum growth is not the objective, we should be
even more wary of
accumulating excessive
debt

Policy implications: escaping the debt overhang
Ultra-loose monetary policy can only ultimately work by reigniting private credit growth
Fiscal policy could stimulate the economy and could be skewed to more sustainable ends
… but appears blocked by public debt sustainability concerns
Money finance of fiscal deficits is the always available option

The case for monetisation
25
The price level should be controlled by “expanding and
contracting issues of actual money…[and]… monetary rules
should be implemented and in turn should largely determine fiscal
policy.” Henry Simons (1936)
“Government expenditures would be financed exclusively by tax revenues or the
creation of money.… the chief function of the monetary authority [should be] the creation of
money to meet government deficits and the retirement of money when the
government has a surplus.” Milton Friedman (1948)
“A tax cut for households and businesses that is explicitly coupled with incremental BoJ purchases of
government debt, so that the tax cut is in effect financed by money creation.. [with it clear that].. much or all of the increase in the money stock is viewed
as permanent”.Ben Bernanke (2003)
