Seminar Why does government debt matter? What can be done about it?
09 Money & Banking English for economics: Geoff Cockayne 2011
What is money? • medium of exchange • store of value • inflation, commoditisation of money • unit of account • elimination of ‘cash’?
Why do we trust money? • backed by gold • UK = £22bn (Telegraph 2011), money supply = £1,500 bn (Bank of England 2011) • government fiat • control of inflation
Classification of money (simplified) • M0 • Notes and coins • M1 • M0 + ‘on demand’ deposits • M2 • M1 + time deposits
Where does money come from? • central bank purchases government bonds: M2 • payment is deposited with private banks: M1/2 • banks lend and issue currency as required: M0/1/2 • money supply determined by demand
How government controls money supply • central bank purchases gov’t bonds • recorded as loan in bank’s accounts • increased M2 • reduced interest rates • increased consumer borrowing The price of bonds is the interest rate. The price (value) of money is 1/inflation.
Exchange rates • increased demand for Chinese goods = increased demand for RMB • increased demand for RMB = increased price of RMB • i.e. more $ required to buy RMB
Is the RMB undervalued? • RMB/$ appreciation since 2000 ≈ 20%.
Is the RMB undervalued? US goods purchases are matched by Chinese bond purchases
International trade • benefits all societies • absolute advantage • comparative advantage • specialisation
