in order to reduce or raise money supply and influence interest rates
2
 Reserve asset requirements: banks are required by central bank as a matter of policy to keep a
certain proportion of its liabilities at the central bank (or on its own but in liquid assets)
2

AD2
Real output
Multiplier effect explains how a change in AD will have far-reaching impact on equilibrium
national income
2
When there is a trigger e.g. a cut in taxes or increased government expenditure, companies will
need to increase production to meet the extra demand
2
On the graph, this is the movement from AD1 to AD2, which increases output from Y1 to Y2 and
the price level from P1 to P2
2
But if supply is inelastic (SRAS3), output increase will not reach Y2 but Y3, thus only aggravate
inflation (new price level will be P3)
2
Also with increased demand the central bank may raise interest rates, thus curtail borrowing by
firms to expand or increase supply
2
QUESTION 7
(a)
Transactions with foreign countries:
 Money supply increases with increases in foreign reserves
1
 So, exports and capital inflows raise money supply
1
 So, imports and capital outflows reduce money supply
1
Government transactions:
 Government deposits at the central bank or sale of Treasury bills for expenditure financing have
the same impact of reducing money supply because liquidity is withdrawn from circulation 1
 The converse is true with the purchase of Treasury bills

Cost-push inflation occurs when firms increase prices to protect margins after facing a rise in the
cost of production
2
When production costs soar, the supply curve shifts inward from AS1 to AS2 and the price goes
up to P2 from P1
2
This causes aggregate demand to fall to Q2 from Q1
2
Causes:
o Rising cost of imports or imported inflation
1
o Rising labour costs

o Higher indirect taxes

The standard Keynesian consumption function is presented as:
C = a + cYd (where C is consumption and Yd is disposable income)
2
Consumer spending rises with income
2
Rise in spending is at a rate below that of income
2
‘a’ is autonomous expenditure, where real disposable income is zero but one still consumes out
of savings (i.e. dis-saving). It is the intercept.
2
‘c’ is the marginal propensity to consume, which falls between 0 and 1. It is the slope of the
consumption function
