Debt, Money and Mephistopheles: How do we get out of this mess? Adair Turner Cass Business School 6 February 2013
Monetary policy and macro-demand: Two issues Targets: - Inflation rates or price levels - Nominal GDP growth rates or levels Tools to achieve targets: - Fiscal or monetary or macro-prudential - Interest rates or QE or credit easing - Helicopter money 1
Devilish money creation: Faust Part II “All this activity degenerates into inflation, destroying the monetary system because the money rapidly loses its value” Jens Weidman , Money Creation and Responsibility , September 2011 2
Money finance as normal procedure: Friedman and Simons “ The powers of the government to inject ‘Under the proposal, government expenditures would be financed entirely by purchasing power through expenditure and to tax revenues or the creation of money, that withdraw it through taxation, i.e. the powers of is, the issue of non-interest bearing expanding and contracting issues of actual securities… The chief function of the money and other obligations more or less monetary authority [would be] the creation serviceable is money – are surely adequate to of money to meet government deficits and price level control. the retirement of money when the … in other words, the monetary rules should government has a surplus” be implemented entirely by, and in turn should largely determine, fiscal policy.” Milton Friedman, A Monetary and Fiscal Henry Simons, Rules and Authorities in Framework for Economic Stability , America Monetary Policy , The Journal of Political Economic Review, Vol 38, June 1948 Economy, Vol 44, No. 1, February 1936 3
Helicopters and old bottles: Friedman and Keynes “ Let us suppose that one day a helicopter flies over this community and drops an additional $1000 in bills from the sky, which is, of course, hastily collected by members of the community” Milton Friedman, The Optimum Quantity of Money, Chapter 1, (1969) “ If the Treasury were to fill old bottles with bank notes, bury them at suitable depths in disused coal mines… and leave it to private enterprise on tried principles of laissez faire to dig the notes up again… there need be no more unemployment… and the real income of the country… would then become a good deal greater than it actually is.” John Maynard Keynes, The General Theory, Chapter 10, Section 6 (1936) 4

Levers and effects Fiscal policy: deficits or Prices surpluses Monetary policy: Aggregate - Interest rates Nominal Demand - QE - Forward guidance = Nominal GDP Central Bank private credit support: - US “credit easing” Real - UK “FLS” output Macro-Prudential Macro-Prudential policy: policy: - Bank capital and - Bank capital and liquidity 6 liquidity standards
Levers and effects O.P.M.F. Fiscal policy: Prices deficits or surpluses Monetary policy: Aggregate - Interest rates - QE Nominal - Forward guidance Demand Central Bank private credit support: - US “credit easing” - UK “FLS” Real output Macro-Prudential policy: - Bank capital and liquidity standards 7
Levers and effects Prices Aggregate Nominal Demand Real output Division determined by • Spare capacity in labour or physical capital • Flexibility of price setting processes in labour or product markets 8
The “independence” assumption O.P.M.F. Fiscal policy Prices Monetary Aggregate policy Nominal Demand Central Bank private credit support Real Division of the effect between output Macro-Prudential Macro- prices and real output is policy: Prudential independent of the tools used to - Bank capital and stimulate nominal demand 9 liquidity standards
Possible contraventions of “independence” Unconventional monetary O.P.M.F. policy or O.P.M.F. create expectations of future price Fiscal policy effects? Monetary Prices policy Aggregate Nominal Demand Central Bank Real private credit output Supply enhancement? support Macro- Fiscal expenditure or credit support targeted to achieve Prudential supply increase as well as demand? 10 10
“ The essence of [the] proposal is that it uses automatic adaptations to the current income stream to offset, at least in part, changes in other segments of aggregate demand and to change appropriately the supply of money. Under the proposal, government expenditures would be financed entirely by tax revenues or the creation of money, that is, the issue of non-interest bearing securities… The chief function of the monetary authority [would be] the creation of money to meet government deficits and the retirement of money when the government has a surplus” Milton Friedman, A Monetary and Fiscal Framework for Economic Stability , America Economic Review, Vol 38, June 1948 11 11
Friedman’s 1948 proposal: a simple illustration Suppose: Nominal GDP = 100 and money supply = 50 Sensible aim is to grow nominal GDP at 4% per annum, allowing for 2% real growth and 2% inflation Then: Equilibrium money supply growth might be around 4% Appropriate increase in money supply is achieved by running fiscal deficit of 2% of GDP, financed entirely by money Money supply grows by 2 (=4% for 50) 12 12
Two simplifying assumptions Stable relationship between money supply and money GDP (constant velocity) All money is base money: no fractional reserve banks; no private money creation “A reform of the monetary and banking system to eliminate both the private creation or destruction of money and discretionary control of the growth of money by the central bank authority” (Friedman, 1948) 13 13
From fractional reserve to 100% reserve banking Fractional Reserve Banking 100% Reserve Banking Central Bank Commercial Money Central Bank Money Commercial Banks supply supply Banks A L A L Notes & Notes & Notes Coins Coins & A L coins Notes & Reserves Deposits Reserves Deposits Reserves Reserves & bank coins deposits & bank deposits Loans Deposit money = Reserves at central bank Deposit money = Multiple of reserves at central bank Total money supply = Base money Total money supply = Multiple of base money 14 14
Laissez faire economics and the banking exception “ in the very nature of the system, banks will flood the economy with money substitutes during booms and precipitate futile effects at general liquidation afterward” “private initiative has been allowed too much freedom in determining the character of our financial structure and in directing changes in the quantity of money and money substitutes.” Henry Simons, Rules versus Authority in Monetary Policy , Journal of Political Economy, Vol 44, February 1936. 15 15
Arguments for fractional reserve banks: Up to a point Some private credit and money creation, may: • Abolishing fractional reserve banks Be essential to optimal almost certainly not optimal mobilisation of savings • But good argument for dramatically Facilitate welfare enhancing increasing smoothing of consumption − The fraction of liquid reserves across life cycle and/or − The fraction of capital resources See Adair Turner “Monetary and Financial Stability: Lessons from the Crisis and from some old Economics Texts” , South Africa Reserve Bank, November 2012. 16 16
Two (lost) insights of early laissez faire writers Banking is special: arguments for laissez faire in other sectors of the economy are not applicable Monetary and financial stability are closely interlinked 17 17

Three drivers of financial instability Debt contracts create specific risks Real economy leverage, Unregulated bank credit and private credit creation dynamics, and money creation is inherently unstable credit/asset price cycles are Lending secured against real assets can crucial macro-economic be strongly pro-cyclical variables, and phenomena 19 19
